Description

Wireless communication method, device and system

Technical Field

The present application relates to the field of communications technologies, and in particular, to a wireless communication method, apparatus, and system.

Background

During the usage of the terminal, during the data and service processing, high-rate data transmission may be performed, which may cause an Overheating (Overheating) problem for the terminal.

In the prior art, in order to solve the problem of overheating of the terminal, when overheating is detected, the terminal may automatically limit the communication capability, and then automatically shut down and start up, so as to perform communication with the limited communication capability. At this time, since the communication capability of the terminal is lowered, the above overheating problem can be solved.

However, in the prior art, when the overheating problem is solved, after the communication capability of the terminal is limited, the terminal needs to be powered off and powered on, which may cause interruption of the service, and further seriously affect the communication process and the user experience.

Disclosure of Invention

The application provides a wireless communication method, a wireless communication device and a wireless communication system, which are used for solving the problems of shutdown and poor user experience of a terminal when the overheating problem of the terminal is processed.

It should be understood that the method in the embodiment of the present application may be executed by a wireless communication apparatus, which may be a complete computer of a computing device, or may be a part of a device in the computing device, for example, a chip related to a wireless communication function, such as a system chip, a communication chip. The System Chip is also called a System on Chip (SoC) Chip. Specifically, the wireless communication apparatus may be a terminal such as a smartphone, and may also be a system chip or a communication chip that can be provided in the terminal. The communication chip may include one or more of a radio frequency processing chip and a baseband processing chip. The baseband processing chip is sometimes also referred to as a modem (modem) or baseband processor. In physical implementation, the communication chip may be integrated inside the SoC chip or may not be integrated with the SoC chip. For example, the baseband processing chip is integrated in the SoC chip, and the radio frequency processing chip is not integrated with the SoC chip.

In a first aspect, the present application provides a wireless communication method applied to a terminal, where the terminal is configured with a Master Cell Group (MCG) and a Secondary Cell Group (SCG), and the method includes:

when the terminal enters an overheating state, sending an auxiliary cell group failure information (SCGfailureinformation) message to the network equipment; receiving a first Radio Resource Control (RRC) reconfiguration (rrcreeconfiguration) message from a network device, wherein the first RRC reconfiguration message is used for instructing to release a secondary cell of a terminal; and releasing the secondary cell of the terminal according to the first RRC reconfiguration message.

It should be understood that the terminal may complete the primary cell group service and the secondary cell group service in the dual-link state, but during the data and service processing, high-rate data transmission may be performed, which may cause overheating of the terminal. In order to solve the overheating problem, whether the terminal is in an overheating state is detected, when the terminal is determined to be in the overheating state, the terminal sends an SCG failure information message to the network equipment, and after the network equipment receives the failure message of the auxiliary cell group, the network equipment needs to send a release instruction to the terminal so as to indicate the terminal to release the auxiliary cell; the terminal receives a first RRC reconfiguration message sent by the network equipment, wherein the first RRC reconfiguration message is used for indicating to release one or more auxiliary cells in the auxiliary cell group configured by the terminal, so that the terminal releases the auxiliary cells.

It should be understood that in a fourth generation mobile communication network (4th-generation, 4G) network system, the RRC reconfiguration message, referred to as an "RRC connection reconfiguration (rrcconnectionreconfiguration) message"; in a fifth generation mobile communication network (5th-generation, 5G) network system, the RRC reconfiguration message is referred to as an "RRC reconfiguration (rrcrconfiguration) message".

The terminal can release the auxiliary cells according to the first RRC reconfiguration message, and the service volume of the terminal can be reduced due to the release of at least one auxiliary cell in the auxiliary cell group; and then reduce the consumption of terminal, reduce the temperature of terminal, avoid the terminal to be in overheated state for a long time.

With reference to the technical solution provided in the first aspect, in a possible implementation manner, the secondary cell group failure information message carries a failure type parameter (failureType), and the failure type parameter is used to indicate that the number of times of radio link control retransmission reaches the maximum number of times.

It should be understood that, in order for the network device to instruct the terminal to release the secondary cell, the terminal needs to indicate through the failure type parameter, and the number of times of radio link control retransmission reaches the maximum number may be indicated through the failure type parameter. In one example, the SCG failure information message may be referred to in a third generation partnership project (3 GPP) protocol specification (e.g., 3GPP TS36.331 V6.2.2). In the section of 3GPP TS36.331 V6.2.2, the failure type parameter is denoted by "failureType-r 12".

With reference to the first aspect or the technical solution provided in any one of the possible embodiments of the first aspect, in a possible embodiment, the first RRC reconfiguration message carries a release parameter; releasing the secondary cell of the terminal according to the first RRC reconfiguration message specifically includes: and releasing all the secondary cells of the terminal according to the first RRC reconfiguration message.

It should be understood that the first RRC reconfiguration message is used to instruct the terminal to release one or more secondary cells in the secondary cell group configured by the terminal. The first RRC reconfiguration message comprises a release parameter or a secondary cell group configuration parameter, wherein the release parameter is used for indicating the release of the secondary cell group, and the secondary cell group configuration parameter is used for indicating the release of part of secondary cells in the secondary cell group. The first RRC reconfiguration message includes a release (release) cell or a setup (setup) cell, where the setup cell carries a secondary cell group configuration cell, and the secondary cell group configuration cell is a sub-cell of the setup cell. For example, the first RRC reconfiguration message may refer to 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2).

The first RRC reconfiguration message is used to instruct to release the secondary cell group of the terminal, that is, the first RRC reconfiguration message is used to instruct to release each secondary cell in the secondary cell group. At this time, the first RRC reconfiguration message carries a release parameter, for example, the release parameter is the release information element; the release parameter is used to indicate the release of the secondary cell group. For example, referring to the 3GPP protocol specification (e.g., 3GPP TS36.331 V6.2.2), if the release parameter is set to a preset value, the release information element indicates that the secondary cell group is released, and the preset value may be 0 or 1.

Further, the terminal releases the secondary cell group.

With reference to the first aspect or the technical solution provided by any one of the possible embodiments of the first aspect, in a possible embodiment, the first RRC reconfiguration message includes a secondary cell group configuration cell, where the secondary cell group configuration cell carries a secondary cell list parameter to be released, and the secondary cell list parameter to be released is used to indicate an index of a secondary cell to be released; releasing the secondary cell of the terminal according to the first RRC reconfiguration message specifically includes: and releasing the secondary cell corresponding to the index of the secondary cell to be released in the secondary cell group configured by the terminal according to the first RRC reconfiguration message.

It should be appreciated that the first RRC reconfiguration message is used to indicate that a portion of the secondary cells in the secondary cell group are released, i.e., the first RRC reconfiguration message indicates that not all of the secondary cells in the secondary cell group are released, but rather indicates that a portion of the secondary cells in the secondary cell group are released. In one example, the first RRC reconfiguration message carries a secondary cell group configuration cell indicating a list parameter of each secondary cell to be released; the list parameter is used to indicate an index of the secondary cell that needs to be released, which may be a cell identifier, for example, a secondary primary cell configuration (spCellConfig) field in a secondary cell group configuration cell, which may indicate an index of the secondary cell, which is a cell identifier. For example, referring to 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2), in the new wireless network architecture, the secondary cell group configuration information element is represented by "nr-SecondaryCellGroupConfig-r 15".

By releasing the appointed auxiliary cell, the terminal temperature can be reduced while the continuity of the service is ensured, and the terminal exits from the overheating state as soon as possible.

With reference to the technical solution provided in the first aspect, in a possible implementation manner, after releasing the secondary cell of the terminal according to the first RRC reconfiguration message, the method further includes: a first RRC reconfiguration complete (rrcreeconfigurationcomplete) message is sent to the network device.

It should be understood that the first RRC reconfiguration complete message is used to confirm that the RRC reconfiguration is complete, and the first RRC reconfiguration complete message is used to characterize that the terminal has released the secondary cell. In 4G network systems, the RRC reconfiguration complete message is called "RRC connection reconfiguration complete (rrcconnectionreconfiguration complete) message"; in the 5G network system, the RRC reconfiguration complete message is an "RRC reconfiguration complete (rrcconfigurationcomplete) message".

With reference to the first aspect or any one of the possible implementations of the first aspect, in a possible implementation, the method further includes: receiving a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises a measurement configuration cell which carries a measurement object, the measurement object comprises a first cell and other cells, and the first cell and an auxiliary cell released by the terminal adopt the same communication system; and sending a measurement report (MeasurementReport) message within a preset time length after the terminal is overheated, wherein the measurement report message carries the measurement results of other cells but does not carry the measurement result of the first cell.

It should be understood that, in order to prevent the terminal from repeatedly exiting from the overheat and entering the overheat state, it is necessary that the terminal does not add the first cell adopting the same communication scheme as the secondary cell released by the terminal within a preset time period after exiting from the overheat state, where the first cell may be the previously released secondary cell or another cell adopting the same communication scheme as the secondary cell released by the terminal.

And the network equipment indicates a measurement object, wherein the measurement object comprises a first cell and other cells, and the first cell and an auxiliary cell released by the terminal adopt the same communication system. Optionally, if the network device deletes the measurement related parameter, resulting in that there is no measurement related parameter in the terminal, the network needs to issue the measurement related parameter.

The terminal can periodically measure the cells within the preset time length to obtain the measurement result of each cell; then, if the measurement result of the first cell meets the reporting standard, the terminal adjusts the measurement result of the first cell to be not in accordance with the reporting standard, so that the measurement result related to the released secondary cell is not sent to the network device within a preset time period, that is, the first measurement report message sent to the network device does not carry the measurement result of the previous first cell, but carries the measurement results of other cells, where the other cells may be cells in which the secondary cell released by the terminal adopts different communication systems; the network device does not instruct the terminal to add the first cell. The terminal cannot add the first cell within the preset time, so that the traffic of the terminal within the preset time after the terminal is overheated is reduced, and the terminal cannot enter an overheating state again. .

It should be understood that, in order to further prevent the terminal from repeatedly exiting from the overheat state and entering the overheat state, it is necessary that the terminal does not add the first cell adopting the same communication system as the secondary cell released by the terminal within a preset time period after exiting from the overheat state. In the above process, in the interaction process between the terminal and the network device, the terminal can release the auxiliary cell without powering off or powering on, so that the service of the terminal is not interrupted, and the terminal can still communicate.

In addition, in order to enable the terminal to exit from the overheat state, the terminal may not add the first cell adopting the same communication scheme as the secondary cell released by the terminal within another preset time after entering the overheat state, where the first cell may be the previously released secondary cell or another cell adopting the same communication scheme as the secondary cell released by the terminal. Therefore, the terminal does not add the first cell in another preset time, the service volume is ensured to be reduced in the preset time, and the temperature of the terminal can be reduced.

With reference to the first aspect or the technical solution provided by any one of the possible embodiments of the first aspect, in a possible embodiment, before the terminal releases the secondary cell, the terminal is in an evolved universal terrestrial radio access new radio dual connectivity (endec) state, where the secondary cell in the secondary cell group is the new radio cell.

Or before the terminal releases the secondary cell, the terminal is in a new radio E-uplink dual connectivity (NEDC) state of the evolution, wherein the secondary cell in the secondary cell group is the evolved universal roadbed radio access cell.

Or, before the terminal releases the secondary cell, the terminal is in a New Radio Dual Connection (NRDC) state, where the secondary cell in the secondary cell group is a New Radio (NR) high frequency cell.

It should be understood that the terminal provided herein is suitable for any of the above DCs. The method of the present application can be implemented when the terminal is in any of the above DC states to solve the overheating problem of the terminal.

With reference to the first aspect or the technical solution provided in any one of the possible embodiments of the first aspect, in a possible embodiment, when the terminal enters an overheat state, sending a secondary cell group failure information message to the network device specifically includes: when the temperature of the terminal is greater than a preset threshold value, sending a failure information message of the auxiliary cell group to the network equipment; wherein the temperature of the terminal is determined by sensing information of a sensor of the terminal.

It should be understood that, determining whether the terminal is in an overheated state, the temperature of the terminal may be detected by a sensor; the sensor can be built in the terminal, or the sensor is externally connected with the terminal; the terminal may then obtain sensing information detected by the sensor, the sensing information being indicative of the temperature of the terminal. Then, the terminal determines whether the terminal is in an overheated state according to the temperature detected by the temperature detecting unit. For example, when the acquired temperature is determined to be equal to or higher than a preset threshold, the state of overheating is determined, or when the temperatures in the continuous preset time are determined to be equal to or higher than the preset threshold, the state of overheating is determined.

In addition, whether the terminal is in an overheating state can be determined through the processing process of the service. For example, if it is determined that the transmission tasks of the data fail within a continuous time, it is determined that the terminal is in an overheat state.

However, in the technical solutions shown in fig. 5 to fig. 6, since the terminal needs to actively trigger the network device to reconfigure the terminal, both the network device and the terminal need to have the capability of supporting terminal deployment, and if the network device or the terminal does not support the capability, the problem of overheating of the terminal cannot be solved in time. In addition, in the technical solutions shown in fig. 5 to fig. 6, the related information of the overheat protection function is placed in the auxiliary information of the user equipment, but there are multiple network systems and multiple types of network equipment at present, and such a configuration is not supported, in which case the overheat problem of the terminal cannot be solved.

As shown in fig. 7, the wireless communication method includes:

701. and when the terminal is in an overheated state, sending a failure information message of the auxiliary cell group to the network equipment.

In one example, the secondary cell group failure information message carries a failure type parameter, where the failure type parameter is used to indicate a Radio Link Control (RLC) to control the number of retransmissions to reach a maximum number.

In one example, step 701 specifically includes: when the temperature of the terminal is greater than a preset threshold value, sending a failure information message of the auxiliary cell group to the network equipment; wherein the temperature of the terminal is determined by sensing information of a sensor of the terminal.

It should be understood that the execution main body of the present embodiment may be a terminal, or a processor in the terminal, or a controller in the terminal, or a chip inside the terminal. The present embodiment is described with an execution subject as a terminal.

As can be seen from the foregoing description, the network device may provide a master cell group service and a slave cell group service for the terminal, and further provide a dual-link communication service for the terminal. The terminal can complete the service of the main cell group and the service of the auxiliary cell group in the double-link state; at this time, the terminal may be configured with a master cell group consisting of at least one master cell and a secondary cell group consisting of at least one secondary cell.

Illustratively, the method of the present embodiment is adapted to dual-link modes of endec, NEDC, NRDC, and the like.

The present embodiment is applicable to the scenario shown in fig. 1, and as shown in fig. 1, the network device in the present embodiment is a network device providing a secondary cell group service.

For another example, fig. 13 is a schematic view of an application scenario three provided by the present application, and as shown in fig. 13, a network device in an LTE network provides a secondary cell group service for a terminal, and a network device in an NR network provides a primary cell group service for the terminal, at this time, the terminal performs communication under NEDC. In the scenario shown in fig. 13, the network device in this embodiment is a network device in an LTE network; the terminal is in a NEDC state and is configured in a main cell group and an auxiliary cell group; wherein, the auxiliary cells in the auxiliary cell group are evolved universal roadbed wireless access cells; the primary cell in the primary cell group is a new radio cell. Alternatively, in fig. 12, the network device integrates the NR network and the LTE network, and may provide the terminal with the secondary cell group service in the LTE network and provide the terminal with the primary cell group service in the NR network. In the scenarios and network systems shown in fig. 13 and 12, before step 703, the terminal is in the endec state, and the terminal is configured with a master cell group and a secondary cell group; wherein, the auxiliary cells in the auxiliary cell group are evolved universal roadbed wireless access cells; the primary cell in the primary cell group is a new radio cell.

For another example, fig. 14 is a schematic view of an application scenario provided by the present application, as shown in fig. 14, a network device in an NR high frequency network provides a secondary cell group service for a terminal, and a network device in an NR low frequency network provides a primary cell group service for the terminal, where the terminal performs communication under NRDC. In the scenario shown in fig. 14, the network device in the present embodiment is a network device in an NR high frequency network. Or, fig. 15 is a schematic view of an application scenario five provided by the present application, and as shown in fig. 15, a network device integrates an NR high frequency network and an NR low frequency network, and can provide a secondary cell group service for a terminal in the NR high frequency network and provide a primary cell group service for the terminal in the NR low frequency network. In the scenarios and network systems shown in fig. 14 and 15, before step 703, the terminal is in NRDC state, and the terminal is configured with a master cell group and a secondary cell group; wherein, the auxiliary cells in the auxiliary cell group are NR high-frequency cells; and the main cell in the main cell group is an NR low-frequency cell.

The terminal may determine whether it is in an overheat state, and there are various ways to determine whether it is in an overheat state, for example, as described below.

(1) Whether the terminal is in an overheated state is determined through sensing information of a sensor in the terminal.

A temperature detection unit is arranged in the terminal, or the terminal is externally connected with a temperature measurement unit which is used for detecting the temperature of the terminal in real time; in one example, the temperature detecting unit is a sensor, the sensor detects the temperature of the terminal, and the terminal can acquire sensing information detected by the sensor, wherein the sensing information represents the temperature of the terminal. Then, the terminal determines whether the terminal is in an overheated state according to the temperature detected by the temperature detecting unit.

For example, when the acquired temperature is determined to be greater than or equal to a preset threshold, determining that the temperature is in an overheating state; and when the acquired temperature is determined to be smaller than the preset threshold value, determining that the temperature is not in an overheating state.

For another example, when the temperatures in the continuous preset time are determined to be greater than or equal to the preset threshold, the state of overheating is determined; and when the temperatures in the continuous preset time are determined to be less than the preset threshold value, determining that the temperature is not in the overheating state, or when the temperatures in the continuous preset time are determined to be not greater than or equal to the preset threshold value, determining that the temperature is not in the overheating state.

For another example, the temperatures within the continuous preset time are acquired, and the temperature average value of the temperatures within the continuous preset time is obtained; if the average temperature value is determined to be greater than or equal to the preset threshold value, determining that the temperature sensor is in an overheating state; and if the temperature average value is smaller than the preset threshold value, determining that the temperature average value is not in an overheating state.

(2) The external equipment informs whether the terminal is in an overheat state.

The terminal is connected with an external device, and the external device has a function of measuring the temperature of the terminal. Then, the external device determines whether the terminal is in an overheated state according to the measured temperature. The external device may notify the terminal that it is in an overheated state. For example, a message is sent to the terminal indicating that the terminal is in an overheat state.

For example, when the external device determines that the acquired temperature is greater than or equal to a preset threshold, it is determined that the terminal is in an overheat state. For another example, when the external device determines that the temperatures within the continuous preset time are all greater than or equal to the preset threshold, it is determined that the terminal is in an overheat state. For another example, the external device obtains temperatures within a continuous preset time, obtains a temperature average value of the temperatures within the continuous preset time, and determines that the terminal is in an overheat state if the temperature average value is greater than or equal to a preset threshold value.

(3) And determining whether the terminal is in an overheating state or not through the service processing process.

The terminal can determine whether the service is successfully processed or not in the process of processing the service, and when the service processing is determined to be failed, the terminal is determined to be in an overheating state.

For example, the terminal transmits data, and if it is determined that the current transmission task of the data fails, it is determined that the terminal is in an overheated state.

For another example, the terminal transmits data, and if it is determined that the data transmission tasks fail within the continuous time, it is determined that the terminal is in an overheated state.

When the terminal is determined to be in the overheating state, the processor of the terminal can transmit a cause value inside, and the cause value represents that the terminal is in the overheating state; the cause value is an internal protocol flow of the terminal, and can be referred to the introduction of 3GPP technical specifications (e.g., 3GPP TS38.331 V5.3.10.3).

When the terminal is determined to be in an overheat state, the terminal sends an auxiliary cell group failure information message to the network equipment; for example, when the temperature of the terminal is greater than a preset threshold, a secondary cell group failure information message is sent to the network device, or when the transmission task continuously fails, a secondary cell group failure information message is sent to the network device. The failure information message of the auxiliary cell group carries failure type parameters; a failure type parameter indicating a cause value of a secondary cell group failure. In one example, a failure type parameter is used to indicate that the number of radio link control retransmissions reaches a maximum number. In one example, the secondary cell group failure information message may also carry other failure type parameters, such as a timer, a random access failure, and a secondary cell group handover failure.

In one example, the SCG failure information message may be referred to in 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2). In the section of 3GPP TS36.331 V6.2.2, the failure type parameter is denoted by "failureType-r 12".

In this step, the secondary cell group failure information message may indicate that at least one secondary cell in the secondary cell group is abnormal, and the network device may indicate whether the terminal goes to the abnormal secondary cell according to the secondary cell group failure information message.

702. Receiving a first RRC reconfiguration message from the network equipment, wherein the first RRC reconfiguration message is used for indicating to release the secondary cell of the terminal.

In one example, the first RRC reconfiguration message carries a release parameter.

In another example, the first RRC reconfiguration message includes a secondary cell group configuration (secondary cell group configuration) cell, where the secondary cell group configuration cell carries a secondary cell list parameter to be released, and the secondary cell list parameter to be released is used to indicate an index of the secondary cell to be released.

It should be understood that, after receiving the secondary cell group failure message, the network device needs to send a release instruction to the terminal, so as to indicate that the terminal can release the secondary cell.

In this embodiment of the present application, after step 701, the network device sends a first RRC reconfiguration message to the terminal. In one example, in a 4G network system, an RRC reconfiguration message, referred to as an "RRC connection reconfiguration message"; in the 5G network system, the RRC reconfiguration message is still referred to as "RRC reconfiguration message". Thus, when the embodiment is applied to the 4G network system, the step is "the network device sends the first RRC connection reconfiguration message to the terminal"; when this embodiment is applied to a 5G network system, this step is still "the network device sends the first RRC reconfiguration message to the terminal".

The first RRC reconfiguration message is used to instruct the terminal to release one or more secondary cells in the secondary cell group configured by the terminal. The first RRC reconfiguration message comprises a release parameter or a secondary cell group configuration parameter, wherein the release parameter is used for indicating the release of the secondary cell group, and the secondary cell group configuration parameter is used for indicating the release of part of secondary cells in the secondary cell group.

For example, the first RRC reconfiguration message includes a release cell or a setup cell, where the setup cell carries a secondary cell group configuration cell, and the secondary cell group configuration cell is a sub-cell of the setup cell. For example, the first RRC reconfiguration message may refer to 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2).

The first RRC reconfiguration message, specific embodiments of which include the following.

(1) In the first embodiment, the first RRC reconfiguration message is used to instruct to release the secondary cell group of the terminal, that is, the first RRC reconfiguration message is used to instruct to release each secondary cell in the secondary cell group. At this time, the first RRC reconfiguration message carries a release parameter, for example, the release parameter is the release information element; the release parameter is used to indicate the release of the secondary cell group. For example, referring to the 3GPP protocol specification (e.g., 3GPP TS36.331 V6.2.2), if the release parameter is set to a preset value, the release information element indicates that the secondary cell group is released, and the preset value may be 0 or 1.

(2) In a second embodiment, the first RRC reconfiguration message is used to instruct to release part of the secondary cells in the secondary cell group, that is, the first RRC reconfiguration message instructs not to release all the secondary cells in the secondary cell group, but to release part of the secondary cells in the secondary cell group. At this time, the first RRC reconfiguration message carries a setup cell, and the setup cell is used for indicating to release part of the auxiliary cells in the auxiliary cell group; also, in order to facilitate the terminal to determine which secondary cells to release, the setup cell also carries a release object, which includes the secondary cell instructed to release, e.g., the setup cell also carries the cell identity of the secondary cell instructed to release. In one example, the first RRC reconfiguration message carries a secondary cell group configuration cell indicating a list parameter of each secondary cell to be released; the list parameter is used to indicate an index of the secondary cell to be released, which may be a cell identifier, for example, a secondary primary cell configuration field in a secondary cell group configuration cell may indicate an index of the secondary cell, which is a cell identifier. For example, referring to 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2), in the new wireless network architecture, the secondary cell group configuration information element is represented by "nr-SecondaryCellGroupConfig-r 15".

703. And releasing at least one secondary cell according to the first RRC reconfiguration message.

Exemplarily, when the first RRC reconfiguration message carries the release parameter, the first RRC reconfiguration message is used to instruct to release the secondary cell group of the terminal, and the terminal may release the secondary cell group after step 702, that is, release all secondary cells of the terminal; and then the terminal enters a single link state, and all auxiliary cell group services are released.

Or when the first RRC reconfiguration message includes the secondary cell group configuration cell, the first RRC reconfiguration message is used to instruct to release part of the secondary cells in the secondary cell group, and the terminal may release part of the secondary cells; the terminal is then still in the dual link state, but has released part of the secondary cell group traffic. In one example, since the secondary cell group configuration cell carries the list parameter of the secondary cell to be released, when the first RRC reconfiguration message includes the secondary cell group configuration cell, in this step, the terminal may determine the index of the corresponding secondary cell to be released according to the list parameter, and further determine which secondary cells need to be released; then, the secondary cell corresponding to the index of the secondary cell to be released is released.

In both cases, the traffic of the terminal can be reduced; because the traffic of the terminal is reduced, the temperature of the terminal can be reduced, and the problem of overheating of the terminal is solved.

For example, the network device in the NR network provides the secondary cell group service to the terminal, and the network device in the LTE network provides the primary cell group service to the terminal. When the terminal downloads the service based on the NR network provided by the network equipment, the average processing speed is V1; when the terminal downloads the service based on the LTE network provided by the network equipment, the average processing speed is V2; within the duration T1, the traffic volume of the terminal is (V1+ V2) × T1. By adopting the technical scheme provided by the embodiment, the terminal releases the auxiliary cell group, and the terminal only downloads the service based on the LTE network, so that the service volume of the terminal is V2 × T1 within the time duration T1. It can be seen that the terminal has (V1+ V2) × T1 under the dual link; after the terminal releases the auxiliary cell group, the traffic volume changes to V2T 1, and the traffic volume is obviously reduced; so that the amount of data processed by the terminal is reduced, thereby lowering the temperature of the terminal.

For another example, the network device in the NR network provides the secondary cell group service to the terminal, and the network device in the LTE network provides the primary cell group service to the terminal. When the terminal downloads the service based on the NR network provided by the network equipment, the average processing speed is V1; when the terminal downloads the service based on the LTE network provided by the network equipment, the average processing speed is V2; within the duration T1, the traffic volume of the terminal is (V1+ V2) × T1. By adopting the technical scheme provided by the embodiment, the terminal releases part of the auxiliary cells of the auxiliary cell group, the terminal downloads the service based on the LTE network, and the terminal downloads the service based on the NR network; at this time, when the terminal downloads the service based on the NR network provided by the network device, the average processing speed is V3, and V3 is smaller than V1; when the terminal downloads the service based on the LTE network provided by the network equipment, the average processing speed is still V2; thus, in the duration T1, the traffic volume of the terminal is (V2+ V3) × T1. It can be seen that the terminal has (V1+ V2) × T1 under the dual link; after the terminal releases part of the secondary cells of the secondary cell group, the traffic becomes (V2+ V3), and since V3 is smaller than V1, the traffic is reduced; so that the amount of data processed by the terminal is reduced, thereby lowering the temperature of the terminal.

In one example, after step 703, step 704 may also be included.

704. And sending a first RRC reconfiguration complete message to the network equipment.

Exemplarily, the terminal needs to inform the network device that the RRC reconfiguration is completed after the secondary cell is released, so that the terminal reports a first RRC reconfiguration complete message to the network device, where the first RRC reconfiguration complete message is used to confirm that the RRC reconfiguration is completed, and the first RRC reconfiguration complete message is used to characterize that the terminal has released the secondary cell. In one example, in a 4G network system, an RRC reconfiguration complete message, referred to as an "RRC connection reconfiguration complete message"; in the 5G network system, the RRC reconfiguration complete message is still referred to as "RRC reconfiguration complete message". Thus, when the present embodiment is applied to the 4G network system, the step is "the terminal sends a first RRC connection reconfiguration complete message to the network device"; when this embodiment is applied to a 5G network system, this step is still "the terminal sends a first RRC reconfiguration complete message to the network device".

In one example, after step 703 or step 704, step 705 may be further included.

705. And sending a measurement report message within a preset time length after the terminal is overheated, wherein the measurement report message carries the measurement results of other cells but does not carry the measurement result of the first cell, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

It should be understood that, in general, in the process of operating a terminal, a cell needs to be periodically measured to obtain a measurement result of the cell; in the obtained measurement results, if the measurement results meet the reporting standard, the terminal reports the measurement results of the corresponding cells to the network equipment; then, the network equipment selects the auxiliary cells meeting the conditions according to the measurement results reported by the terminal, and then instructs the terminal to add the auxiliary cells meeting the conditions to the auxiliary cell group. However, in this embodiment, in order to prevent the terminal from repeatedly exiting from the overheat and entering the overheat state, it is necessary that the terminal does not add the first cell adopting the same communication scheme as the secondary cell released by the terminal within the preset time period after exiting from the overheat state, where the first cell may be the previously released secondary cell or another cell adopting the same communication scheme as the secondary cell released by the terminal.

The terminal can detect whether the terminal exits from the overheating state in real time. There are various ways of determining whether to exit the overheat condition, such as described below.

(1) In the first mode, a temperature detection unit is configured inside the terminal, or the terminal is externally connected with a temperature measurement unit, and the temperature detection unit is used for detecting the temperature of the terminal in real time; in one example, the temperature detection unit is a sensor that detects a temperature of the terminal, and the terminal may acquire the temperature detected by the sensor. Then, the terminal determines whether the terminal exits the overheated state according to the temperature detected by the temperature detecting unit.

For example, when it is determined that the acquired temperature is less than a preset threshold, it is determined that the overheat state is exited; and when the terminal determines that the acquired temperature is greater than or equal to the preset threshold, determining that the terminal is still in an overheat state.

For another example, when the temperatures within the continuous preset time are determined to be less than the preset threshold, determining to exit the overheat state, or when the temperatures within the continuous preset time are determined not to be greater than or equal to the preset threshold, determining to exit the overheat state; when the temperatures in the continuous preset time are determined to be greater than or equal to a preset threshold value, determining that the temperature is still in an overheating state;

for another example, the temperatures within the continuous preset time are acquired, and the temperature average value of the temperatures within the continuous preset time is obtained; if the average temperature value is smaller than the preset threshold value, determining to exit from the overheating state; and if the average temperature value is determined to be greater than or equal to the preset threshold value, determining that the temperature is still in an overheating state.

(2) And in the second mode, the terminal is connected with an external device, and the external device has the function of measuring the temperature of the terminal. And then, the external equipment determines whether the terminal is in an overheating state or not according to the measured temperature. The external device may notify the terminal that it is in an overheated state.

For example, when the external device determines that the acquired temperature is less than the preset threshold, it is determined that the terminal exits from the overheat state. For another example, when the external device determines that the temperature within the continuous preset time and the average cell is equal to the preset threshold, it is determined that the terminal exits the overheat state. For another example, the external device obtains temperatures within a continuous preset time, obtains a temperature average value for the temperatures within the continuous preset time, and determines that the terminal is in an overheat state if the temperature average value is smaller than a preset threshold value.

(3) And in the third mode, the terminal can determine whether the service is successfully processed or not in the process of processing the service, and determines that the terminal exits from the overheat state when the service is successfully processed.

For example, the terminal transmits the designated data, and if the current transmission task of the data is determined to be successful, the terminal is determined to exit the overheat state.

For another example, the terminal transmits the designated data, and if the data transmission task in the continuous time is determined to be successful, the terminal is determined to exit from the overheat state.

In one example, the processor of the terminal may communicate internally a cause value that characterizes the terminal as exiting the over-temperature condition; the cause value is an internal protocol flow of the terminal, and can be referred to the introduction of 3GPP protocol specifications (e.g., 3GPP TS38.331 V5.3.10.3).

The terminal periodically measures the cells within a preset time length after determining that the terminal exits from the overheating state, and obtains the measurement result of each cell; then, if the measurement result of the first cell meets the reporting standard, the terminal adjusts the measurement result of the first cell to be not in accordance with the reporting standard, so that the measurement result related to the released secondary cell is not sent to the network device within a preset time period, that is, the first measurement report message sent to the network device does not carry the measurement result of the previous first cell, but carries the measurement results of other cells, where the other cells may be cells in which the secondary cell released by the terminal adopts different communication systems; the network device does not instruct the terminal to add the first cell. The terminal cannot be added with the first cell within preset time, so that the terminal is prevented from repeatedly exiting from an overheating state and then entering into an overheating state, the service volume is guaranteed to be reduced within the preset time, and the terminal cannot enter into the overheating state again. It should be noted that, in this process, if the measured measurement result of the first cell is not in compliance with the reporting standard, the terminal does not send the measurement result related to the released secondary cell to the network device within a preset time duration, that is, the first measurement report message sent to the network device does not carry the measurement result of the first cell before, but carries the measurement results of the other cells.

The method for sending the measurement report message within the preset time length may adopt the following several methods.

(1) A timer can be set, and the timer is provided with the preset duration; and the terminal starts a timer after entering an overheating state, and sends a measurement report message within the preset time length, wherein the measurement report message carries the measurement results of other cells but does not carry the measurement result of the first cell.

(2) And the protocol specifies a preset time length, and specifies that the measurement report message is sent within the preset time length after the overheating state exits, wherein the measurement report message carries the measurement results of other cells but does not carry the measurement result of the first cell.

The preset time length can be 0 or a positive number greater than 0; the value of the preset duration can be determined according to an empirical value.

Here, it is understood that the size of the preset time period is not limited, and may be preset by the system. In particular, the timer may be implemented by software, such as a piece of code or a program having a timer function. Alternatively, it may be implemented in hardware, such as a special hardware timer in the terminal baseband processor or system chip. Or, it can also be realized by combining software and hardware, for example, using a specific hardware timer in the terminal baseband processor or system chip, combining a code or program with counting function, counting for 1 time every time the hardware timer reaches the preset time, and when the product of the number of times and the hardware timer duration reaches the preset duration, terminating the above-mentioned inhibiting action, and recovering normal terminal capability reporting.

For example, when the first RRC reconfiguration message indicates to release the secondary cell group, in this step, the terminal periodically measures the cells within a preset time length after exiting the overheat state, and may detect the measurement result of the secondary cell in the secondary cell group and may also detect the measurement result of the primary cell in the primary cell group; if the measurement result of the auxiliary cell does not accord with the reporting standard, the first measurement report message sent by the terminal to the network equipment does not carry the measurement result of the auxiliary cell group, but carries the measurement result of the main cell which accords with the reporting standard; if the measurement result of the auxiliary cell meets the reporting standard, the terminal adjusts the measurement result of the auxiliary cell to the measurement result which does not meet the reporting standard, and then the first measurement report message sent to the network equipment does not carry the measurement result of the auxiliary cell group, but carries the measurement result of the main cell which meets the reporting standard. For example, the first measurement report message includes a measurement result (MeasResults) information element indicating a measurement result of the primary cell that meets the reporting criteria.

For another example, when the first RRC reconfiguration message indicates to release part of the secondary cells, in this step, the terminal periodically measures the cells within a preset time length after exiting the overheat state, and the terminal detects the measurement result of the secondary cells in the secondary cell group and may also detect the measurement result of the primary cell in the primary cell group; if the measurement result of the first cell is determined to be not in accordance with the reporting standard, a first measurement report message sent by the terminal to the network equipment does not carry the measurement result of the first cell, but carries the measurement result of the main cell in accordance with the reporting standard; if the measurement result of the first cell is determined to meet the reporting standard, the terminal adjusts the measurement result of the first cell into a measurement result which does not meet the reporting standard, and then a first measurement report message sent to the network equipment does not carry the measurement result of the first cell but carries the measurement result of the main cell which meets the reporting standard; and the first cell and the auxiliary cell released by the terminal adopt the same communication system. For example, the first measurement report message includes a measurement result cell, where the measurement result cell is used to indicate a measurement result of a primary cell meeting the reporting standard and a measurement result of another cell meeting the reporting standard, where the another cell may be another cell that uses a different communication system from the secondary cell released by the terminal.

In the above process, when the terminal measures each cell, the terminal may measure an event. Events, such as any one or more of the following: event B1(eventB1), event B2(eventB2), event a4, event a 5. In the NR network architecture, event B1 is referred to as event B1NR (eventB1-NR), and event B2 is referred to as event B2NR (eventB 2-NR).

In addition, in order to cool down the terminal within another preset time period so as to exit the overheat state, the terminal may not add the first cell adopting the same communication scheme as the secondary cell released by the terminal within another preset time period after entering the overheat state, where the first cell may be the secondary cell released previously or another cell adopting the same communication scheme as the secondary cell released by the terminal. Therefore, the terminal does not add the first cell in another preset time, the service volume is ensured to be reduced in another preset time, and the temperature of the terminal can be reduced. The another preset time length may be 0, or may be a positive number greater than 0; the value of the preset duration can be determined according to an empirical value.

In the embodiment, a terminal is configured with a main cell group and an auxiliary cell group, and when the terminal is determined to be overheated, an auxiliary cell group failure information message is sent to network equipment; therefore, the network equipment returns a first RRC reconfiguration message to the terminal, and the first RRC reconfiguration message indicates to release the secondary cell of the terminal; the terminal can release the auxiliary cells according to the first RRC reconfiguration message, and the service volume of the terminal can be reduced due to the release of at least one auxiliary cell in the auxiliary cell group; and then reduce the consumption of terminal, reduce the temperature of terminal, avoid the terminal to be in overheated state for a long time. In order to prevent the terminal from repeatedly exiting from the overheat state and entering the overheat state, the terminal is required not to add the first cell adopting the same communication system as the auxiliary cell released by the terminal within a preset time length after exiting from the overheat state. In the process, in the interaction process of the terminal and the network equipment, the terminal can release the auxiliary cell without powering off or powering on, so that the service of the terminal is not interrupted, the terminal can still communicate, and the user experience is improved. The above process provided by the embodiment of the present application still is that the network device actively triggers the terminal to complete the reconfiguration of the communication capability, and conforms to the configuration of the current and future 5G network systems and network devices.

Fig. 8 is another wireless communication method according to an embodiment of the present disclosure. The wireless communication method can be used in the method of the embodiment of the present application, and can be executed by the terminal or a chip inside the terminal. As shown in fig. 8, the wireless communication method includes:

801. and when the terminal enters an overheating state, sending a failure information message of the auxiliary cell group to the network equipment.

803. And releasing the secondary cell of the terminal according to the first RRC reconfiguration message.

It should be understood that this step is referred to as step 703 shown in fig. 7, and is not described in detail.

804. And sending a first RRC reconfiguration complete message to the network equipment.

It should be understood that this step is referred to as step 704 shown in fig. 7, and will not be described in detail.

805. And receiving a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises a measurement configuration cell which carries a measurement object, the measurement object comprises a first cell and other cells, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

It should be understood that, the difference from the embodiment shown in fig. 7 is that the network device is required to indicate the measurement object, where the measurement object includes the first cell and other cells, where the first cell and the secondary cell released by the terminal use the same communication system. Optionally, if the network device deletes the measurement related parameter, resulting in no measurement related parameter in the terminal, the network needs to issue the measurement related parameter; wherein, the related measurement parameters are used for generating 'events'.

In an example, the network device sends a second RRC reconfiguration message to the terminal, where the second RRC reconfiguration message includes a measurement configuration cell, and the measurement configuration cell carries the measurement object, and optionally, the measurement configuration cell may also carry the measurement related parameter. For example, the measurement configuration information element includes a field (measObjectToRemoveList) indicating a measurement object and a field (reportConfigToAddModList) indicating a measurement related parameter of a cell.

In another example, the second RRC reconfiguration message is an RRC message, wherein the RRC message includes a measurement object (MeasObject) information element, a report configuration (reportConfig) information element; the measurement target cell is used for indicating the measurement object; the report configuration information element is used for indicating the measurement related parameters.

It should be understood that this step is referred to as step 705 shown in fig. 7, and will not be described in detail.

The technical effects of this embodiment are shown in fig. 7, and are not described again.

Fig. 9 is a diagram of another wireless communication method according to an embodiment of the present application. The wireless communication method can be used in the method of the embodiment of the present application, and can be executed by the terminal or a chip inside the terminal. As shown in fig. 9, the wireless communication method includes:

901. and when the terminal enters an overheating state, sending a failure information message of the auxiliary cell group to the network equipment.

For example, this step is referred to as step 701 shown in fig. 7, and is not described again.

902. Receiving a first RRC reconfiguration message from the network equipment, wherein the first RRC reconfiguration message is used for indicating to release the secondary cell of the terminal.

For example, this step is referred to as step 702 shown in fig. 7, and is not described again.

903. And releasing the secondary cell of the terminal according to the first RRC reconfiguration message.

For example, this step is referred to as step 703 shown in fig. 7, and is not described again.

904. And sending a first RRC reconfiguration complete message to the network equipment.

For example, this step is referred to as step 704 shown in fig. 7, and is not described again.

905. And receiving a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises a measurement configuration cell which carries a measurement object, the measurement object comprises a first cell and other cells, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

For example, this step is referred to as step 805 shown in fig. 8, and is not described again.

906. And sending a measurement report message within a preset time length after the terminal is overheated, wherein the measurement report message carries the measurement results of other cells but does not carry the measurement result of the first cell, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

907. And after the terminal exits from the overheat state, sending a measurement report message to the network equipment, wherein the measurement report message carries a measurement result of the first cell meeting the reporting standard, and the first cell and the auxiliary cell released by the terminal adopt the same communication system.

For example, the terminal may detect whether it exits the overheat state in real time. There are various ways to determine whether to exit the overheat state, which can be referred to the description of step 705 in fig. 7 and will not be described again.

After the terminal is determined to exit from the overheat state, the terminal normally measures the cell to obtain a cell measurement result; in the obtained measurement results, if the measurement results meet the reporting standard, the terminal reports the measurement results of the corresponding cell to the network device. Therefore, in this step, in order to add the previously released secondary cell again, the terminal periodically measures the cells, and may detect the measurement result of the secondary cell in the secondary cell group, and may also detect the measurement result of the primary cell in the primary cell group; determining whether the measurement result of the secondary cell meets the reporting standard, and determining that the measurement result release of the primary cell meets the reporting standard, where a measurement report message sent by the terminal to the network device may carry the measurement result of a first cell meeting the reporting standard, and may also carry the measurement results of other cells meeting the reporting standard, where the first cell may be a previously released secondary cell, or may be a cell that uses the same communication scheme as the secondary cell released by the terminal, and the other cells may be primary cells, or previously unreleased secondary cells.

In one example, the measurement report message includes a measurement result information element, where the measurement result information element is used to indicate a measurement result of the first cell meeting the reporting criteria and a measurement result of the primary cell meeting the reporting criteria, and the measurement result includes a cell identifier and a measurement parameter. For example, the second measurement report message may be referred to a 3GPP protocol specification (e.g., 3GPP TS36.331 V6.2.2).

In the above process, when the terminal measures each cell, the terminal may measure an event. For example, in the case that the terminal releases the secondary cell group, in this step, the terminal may measure event B1 and/or event B2; in the case where the terminal releases part of the secondary cells of the secondary cell group, the terminal may measure event a4 and/or event a5 in this step.

In this step, since the network device does not delete the measurement related parameters of the terminal and thus has the measurement related parameters in the terminal, this step may be directly performed after step 906.

Optionally, in another embodiment, in step 905, the second RRC reconfiguration message includes a measurement configuration cell, where the measurement configuration cell carries a measurement object and measurement related parameters, where the measurement object includes a first cell and other cells, and the first cell and a secondary cell released by the terminal use the same communication system. It should be understood that, if the network device deletes the measurement related parameters of the terminal, resulting in no measurement related parameters in the terminal, the second RRC reconfiguration message may also carry the measurement related parameters, where the measurement related parameters are used to generate an "event".

908. And receiving a third RRC reconfiguration message sent by the network equipment, wherein the third RRC reconfiguration message is used for indicating that a cell meeting the reporting standard is added.

Illustratively, after receiving the measurement report message of step 906, the network device sends a third RRC reconfiguration message to the terminal, where the third RRC reconfiguration message instructs the terminal to add a cell meeting the reporting standard, where the cell may be the first cell that indicates meeting the reporting standard, or may be a primary cell meeting the reporting standard. For example, the third RRC reconfiguration message may be referred to in 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2).

In one example, the third RRC reconfiguration message includes a setup cell, where the setup cell is used to indicate that a secondary cell and/or a primary cell meeting a reporting standard is added; and establishing an auxiliary cell group configuration cell in the cell for indicating an auxiliary cell group parameter and a main cell group parameter, wherein the auxiliary cell group parameter comprises a cell identifier of the auxiliary cell, and the main cell group parameter comprises a cell identifier of the main cell. The auxiliary cell group configuration cell is a sub-cell of the establishment cell.

When the present embodiment is applied to the 4G network system, this step is "the terminal receives the third RRC connection reconfiguration message sent by the network device"; when this embodiment is applied to a 5G network system, this step is still "the terminal receives the third RRC reconfiguration message sent by the network device".

909. And adding the cells meeting the reporting standard according to the third RRC reconfiguration message.

Illustratively, the third RRC reconfiguration message indicates which secondary cells can be added, and the terminal can add the secondary cells indicated by the third RRC reconfiguration message, where the secondary cells meet the reporting criteria.

910. And sending a second RRC reconfiguration complete message to the network equipment.

Exemplarily, the terminal needs to inform the network device that the RRC reconfiguration is completed after the secondary cell is added, so that the terminal reports a second RRC reconfiguration complete message to the network device, where the second RRC reconfiguration complete message is used to confirm that the RRC reconfiguration is completed, and the second RRC reconfiguration complete message is used to confirm that the terminal has added the cell.

When the embodiment is applied to the 4G network system, the step is "the terminal sends a second RRC connection reconfiguration complete message to the network device"; when this embodiment is applied to a 5G network system, this step is still "the terminal sends a second RRC reconfiguration complete message to the network device".

In this embodiment, on the basis of the embodiment shown in fig. 7 or fig. 8, after determining that the terminal exits from the overheat state, the terminal sends a measurement report message to the network device, where the measurement report message carries a measurement result of the first cell meeting the reporting standard; and the terminal adds the cells meeting the reporting standard according to the third RRC reconfiguration message sent by the network equipment. Through the above process, the terminal recovers the normal auxiliary cell adding process after determining to exit from overheating, and can add the auxiliary cell released previously, thereby recovering the previous traffic and communication capacity.

Fig. 10 is a diagram of another wireless communication method according to an embodiment of the present application. The wireless communication method can be used in the method of the embodiment of the present application, and can be executed by the terminal or a chip inside the terminal. As shown in fig. 10, the wireless communication method includes:

1001. and when the terminal enters an overheating state, sending a failure information message of the auxiliary cell group to the network equipment.

1002. Receiving a first RRC reconfiguration message from the network equipment, wherein the first RRC reconfiguration message is used for indicating to release the secondary cell of the terminal.

1003. And releasing the secondary cell of the terminal according to the first RRC reconfiguration message.

1004. And sending a first RRC reconfiguration complete message to the network equipment.

1005. And receiving a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises a measurement configuration cell which carries a measurement object, the measurement object comprises a first cell and other cells, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

1006. And sending a measurement report message within a preset time length after the terminal enters and exits from overheating, wherein the measurement report message carries measurement results of other cells but does not carry the measurement result of a first cell, and the first cell and an auxiliary cell released by the terminal adopt the same communication system.

1007. And receiving a fourth RRC reconfiguration message sent by the network equipment after the preset duration, wherein the fourth RRC reconfiguration message is used for indicating to add the cell.

For example, if the terminal releases part of the secondary cells in the secondary cell group in step 1003, the terminal may add the secondary cells again in a blind addition manner. In this step, after step 1006, after the preset duration indicated in step 1006, the network device sends a fourth RRC reconfiguration message to the terminal, where the fourth RRC reconfiguration message indicates that the terminal adds the auxiliary cell group, or the fourth RRC reconfiguration message indicates that the terminal adds part of the auxiliary cells in the auxiliary cell group. For example, the fourth RRC reconfiguration message may refer to 3GPP protocol specifications (e.g., 3GPP TS36.331 V6.2.2).

In an example, the fourth RRC reconfiguration message includes a measurement configuration information element, where the measurement configuration information element is used to indicate a cell, and the cell may be a primary cell, a secondary cell released previously, or a communication system the same as that of the secondary cell released by the terminal. For example, the secondary cell group configuration cell in the measurement configuration cell is used to indicate a measurement object, and the measurement object may be a primary cell, or a previously released secondary cell, or a communication system that is the same as the communication system used by the secondary cell released by the terminal.

When the embodiment is applied to the 4G network system, this step is "receiving a fourth RRC connection reconfiguration message sent by the network device after a preset duration"; when this embodiment is applied to a 5G network system, this step is still "receiving a fourth RRC reconfiguration message sent by the network device after the preset duration".

1008. And adding the cell according to the fourth RRC reconfiguration message.

For example, the fourth RRC reconfiguration message indicates which cells may be added, and the terminal may add the cell indicated by the fourth RRC reconfiguration message, where the cell meets the reporting criteria or does not meet the reporting criteria.

1009. And sending a third RRC reconfiguration complete message to the network equipment.

Exemplarily, the terminal needs to inform the network device that the RRC reconfiguration is completed after the secondary cell is added, so that the terminal reports a third RRC reconfiguration complete message to the network device, where the third RRC reconfiguration complete message is used to confirm that the RRC reconfiguration is completed, and the third RRC reconfiguration complete message is used to confirm that the terminal has added the cell.

In this embodiment, on the basis of the embodiment shown in fig. 7 or fig. 8, after determining that the terminal exits from the overheat state, the terminal adds the secondary cell in a blind addition manner. Through the above process, the terminal recovers the function of normally adding the cell after determining to quit overheating, and can add the previously released auxiliary cell or the cell having the same network system as the auxiliary cell, thereby recovering the previous traffic and communication capacity.

Fig. 16 is a diagram of another wireless communication method according to an embodiment of the present application. The wireless communication method can be used in the method of the embodiment of the present application, and can be executed by a network device or a chip inside the network device.

1602. And sending an RRC reconfiguration message to the terminal, wherein the RRC reconfiguration message is used for indicating to release the secondary cell of the terminal.

In one example, the RRC reconfiguration message carries a release parameter; the RRC reconfiguration message is used to instruct to release all secondary cells of the terminal.

Or, in another example, the RRC reconfiguration message includes a secondary cell group configuration cell, where the secondary cell group configuration cell carries a secondary cell list parameter to be released, and the secondary cell list parameter to be released is used to indicate an index of the secondary cell to be released; and the RRC reconfiguration message is used for indicating the auxiliary cell corresponding to the index of the auxiliary cell to be released in the auxiliary cell group configured by the release terminal.
