Description

Method, device and system for activating/deactivating secondary cell

The invention relates to the technical field of communication, in particular to a method, a device and a system for activating/deactivating a secondary cell.

Background

Currently, in order to increase the transmission rate of a wireless network and enhance the user experience, the third Generation Partnership project (3 rd Generation Partnership project, 3 GPP) proposes cell network enhancements. Specifically, the method comprises the following steps: a plurality of small base stations using high-frequency-band carriers are added in a macro network formed by macro base stations using low-frequency-band carriers, and a User Equipment (UE) is provided with services jointly through a cell managed by the macro base station and a small cell managed by the small base stations.

In general, in the process of implementing small cell network enhancement, a Macro base station (Macro evolved Node B, MeNB) is used as a Master base station (Master eNB), and a small base station is used

(Small eNB, SeNB) as a Secondary base station (Secondary eNB). The Primary base station may manage a plurality of cells, one of the cells may be selected as a Primary Cell (PCell) of the UE, and one or more other cells may be selected as secondary cells of the UE

(Secondary Cell, SCell). The secondary base station (referred to herein as a "small base station") manages a plurality of small cells, one or more of which may be selected as the secondary cells of the UE. The primary cell mainly establishes a Radio Resource Control (RRC) connection for the UE when establishing an initial connection or switching a serving secondary cell, and provides parameters related to security and mobility management for the UE; the serving secondary cell refers to a secondary cell serving the UE. The secondary cell is mainly responsible for transmitting user plane data for the UE. It should be noted that the secondary cell of the UE may include: a serving secondary cell of the UE, and secondary cells other than the serving secondary cell of the UE (i.e., secondary cells in a secondary cell list configured for the UE) that can provide service for the UE. In a densely deployed network of secondary cells, the serving secondary cell of the UE is frequently updated when the UE moves at a medium-high speed. The procedure of updating the serving secondary cell of the UE may be: the UE measures the signal quality of the secondary cells in the secondary cell list configured for the UE to obtain a measurement result; when the measurement result for a certain secondary cell meets the reporting condition, a Random Access (RA) process is actively initiated to a secondary base station managing the secondary cell to request the secondary base station to activate the secondary cell for the secondary base station, so as to provide service for the UE. In the above process of updating the serving secondary cell of the UE, the UE actively initiates an RA procedure to the secondary base station, which may cause the UE to access an unsuitable cell on one hand and may cause a large RRC signaling overhead on the other hand.

For example, the embodiments of the present invention may be applied to a wireless network System, for example, a Long Term Evolution (LTE) System and a Universal Mobile Telecommunications System (UMTS); the method is particularly suitable for the wireless network systems under the scene of updating the serving secondary cell of the UE when the UE moves at medium and high speed.

The secondary cell of the UE may include: serving secondary cells of the UE and/or secondary cells in a secondary cell list configured for the UE.

Step 101 may specifically include the following cases:

1) The UE determines that a trigger condition to deactivate a serving secondary cell of the UE is satisfied. In this case, the "secondary cell of the UE" is the serving secondary cell of the UE.

2) The UE determines that a trigger condition is satisfied to activate a secondary cell in a secondary cell list configured for the UE. In this case, the "secondary cell of the UE" is a secondary cell in a secondary cell list configured for the UE.

3) The UE determines that a trigger condition to deactivate a serving secondary cell of the UE and a trigger condition to activate a secondary cell in a secondary cell list configured for the UE are satisfied. In this case, the "secondary cell of the UE" is the serving secondary cell of the UE and the secondary cells in the secondary cell list configured for the UE. It should be noted that, the triggering condition for activating and/or deactivating the secondary cell of the UE and the obtaining method thereof, and how the UE determines that the triggering condition is satisfied, are not limited in the embodiments of the present invention.

102, sending an activation/deactivation request message to the master base station in case that said determination satisfies said trigger condition; wherein the activation/deactivation request message is used for the primary base station to determine one or more secondary cells activated and/or deactivated by the UE. Illustratively, the master base station is typically a macro base station serving the UE. The activation/deactivation request message may contain one of the following pieces of information:

1) Information of secondary cells requesting activation and/or deactivation; the information of the secondary cell requesting activation and/or deactivation may be the number or frequency information of the secondary cell requesting activation and/or deactivation, or may be the information shown in table 1 in embodiment 1.

2) And the secondary serving base station of the UE no longer provides the indication information of the service for the UE.

3) And the serving secondary base station of the UE does not activate the indication information of other secondary cells for the UE any more.

4) And the serving secondary base station of the UE deactivates the indication information of all secondary cells managed by the serving secondary base station. Optionally, the activation/deactivation request message may specifically be: a Media Access Control (MAC) Control Element (CE) message, or an RRC message, or a Physical (PHY) layer message. It should be noted that, in specific implementation, the activation/deactivation request message may also be a new message or carried in other messages.

And 104, updating the serving secondary cell of the UE according to the information of the one or more secondary cells activated and/or deactivated for the UE.

Exemplarily, the one or more secondary cells activated and/or deactivated by the UE are set as: m secondary cells activated for the UE (where m secondary cells refer to secondary cells in a secondary cell list configured for the UE) and n serving secondary cells deactivated for the UE, where m and n are integers, and m > 1, and n > K, then step 104 may specifically be: and the UE activates the m secondary cells according to the m secondary cells activated for the UE and/or deactivates the n serving secondary cells according to the n serving secondary cells deactivated for the UE, thereby realizing the updating of the monthly good service secondary cells of the UE. Prior to activation, the m secondary cells are not serving secondary cells for the UE; after activation, the m secondary cells become the good-service secondary cells of the UE. Similarly, prior to deactivation, the n-month good secondary cell is a month good secondary cell of the UE; after deactivation, the n secondary serving cells are not the serving secondary cell for the UE. In an embodiment of the present invention, before step 101, the method may further include:

a) And measuring the signal quality of a secondary cell in a secondary cell list configured for the UE and/or the signal quality of a serving secondary cell of the UE to obtain a measurement result.

And 3, measuring the signal quality of the secondary cell in the secondary cell list of the UE to obtain a first measurement result, and measuring the signal quality of the serving secondary cell of the UE to obtain a second measurement result. In this case, the "determining that the measurement result satisfies a trigger condition for activating and/or deactivating the secondary cell of the UE" may specifically be: determining that a difference between the first measurement and the second measurement is greater than or equal to a third threshold. For example, the first threshold, the second threshold, and the third threshold may each be a specific value or a range of values. When the thresholds are a range of values, for example, the first threshold is a range of values, the measurement result being less than or equal to the first threshold means that the measurement result is less than or equal to the smallest value in the range of values. The specific numerical value or the numerical range can be set according to actual needs or experience.

It should be noted that the UE may report the measurement result based on the RLM or the measurement result based on the CQI measurement to the primary base station, and certainly, the measurement result may not be reported. Optionally, the activation/deactivation request message may further include information of the range of the signal quality of the measurement result.

In the scheme, the UE can realize the updating of the monthly good service sub-cell of the UE without initiating an RA process to the sub-base station, so that compared with the prior art, the scheme can avoid the UE from accessing the unsuitable cell on one hand, and can also reduce RRC signaling overhead on the other hand.

EXAMPLE III

In this embodiment, a method for activating/deactivating a secondary cell is described from the perspective of a serving secondary base station side, where the UE described in this embodiment may be the UE described in the first embodiment and the embodiment, the primary base station described in this embodiment may be the primary base station described in the first embodiment and the second embodiment, and the secondary base station described in this embodiment may be the secondary base station described in the first embodiment and providing a service to the UE. In this embodiment, the actions performed by the user equipment side and the related explanations may refer to the first embodiment, which is not described again in this embodiment.

As shown in fig. 3, the method includes:

a serving secondary base station determines activation/deactivation indication messages for User Equipment (UE); wherein the activation/deactivation indication message contains at least one of the following information: the indication information that the serving secondary base station no longer provides service for the UE comprises indication information that the serving secondary base station no longer activates other secondary cells for the UE, and indication information that the serving secondary base station deactivates all secondary cells managed by the serving secondary base station. For example, the embodiment of the present invention does not limit the trigger condition for the serving secondary base station to determine the activation/deactivation indication message for the UE. The method specifically comprises the following steps:

1) When the serving secondary base station does not provide service for the UE any more, the serving secondary base station determines an activation/deactivation indication message for the UE; in this case, the activation/deactivation indication message includes indication information that the serving secondary base station does not activate other secondary cells for the UE any more;

2) When the serving secondary base station does not activate other secondary cells for the UE any more, the serving secondary base station determines an activation/deactivation indication message for the UE; in this case, the activation/deactivation indication message includes indication information that the serving secondary base station no longer activates other secondary cells for the UE;

3) When the serving secondary base station deactivates all secondary cells managed by the serving secondary base station, the serving secondary base station determines an activation/deactivation indication message for the UE; in this case, the activation/deactivation indication message contains indication information that the serving secondary base station deactivates all secondary cells managed by the serving secondary base station.

Sending the activation/deactivation indication message to the UE, wherein the activation/deactivation indication message is used for enabling the UE to send an activation/deactivation request message to a main base station, and the activation/deactivation request message is used for enabling the main base station to update a service secondary cell of the UE. It should be noted that, the process of updating the serving secondary cell of the UE by the primary base station through the activation/deactivation request message may refer to relevant parts of embodiment two, and details are not repeated here. In the method for activating/deactivating the secondary cell provided by the embodiment of the invention, the secondary serving base station transmits an activation/deactivation indication message to the UE, so that the UE transmits an activation/deactivation request message to the main base station; the activation/deactivation request message is used to cause the primary base station to update the serving secondary cell of the UE. In the scheme, the UE can realize the updating of the service secondary cell of the UE without initiating an RA process to the secondary base station, so that compared with the prior art, the scheme can avoid the UE from accessing the unsuitable cell on one hand, and can also reduce RRC signaling overhead on the other hand.

The method is explained. Example 1

In this embodiment, the secondary cell list configured for the UE includes a secondary cell 1, a secondary cell 2, and a secondary cell 3, and the serving secondary cell of the UE is: serving secondary cell a, serving secondary cell B. The secondary cell 1, the secondary cell 2, and the secondary cell 3 are secondary cells managed by the secondary base station a, and the serving secondary cell a and the serving secondary cell B are secondary cells managed by the (serving) secondary base station B. As shown in fig. 4, the method includes:

UE carries out RRM measurement on the signal quality of secondary cells in a secondary cell list configured for the UE to obtain a first measurement result based on RRM; and performing RRM measurement on the signal quality of the serving secondary cell of the UE to obtain a second measurement result based on RRM. For example, in a specific implementation, the primary base station or the secondary base station may configure the secondary cell list for the UE, in this embodiment, the primary base station is taken as an example to configure the secondary cell list for the UE, and a specific configuration process may refer to steps 400.1 to 400.4 described below. Step 401 specifically includes: the UE respectively measures the signal quality of a secondary cell 1, a secondary cell 2 and a secondary cell 3 to obtain a first measurement result; and measuring the signal quality of the serving secondary cell A and the serving secondary cell B to obtain a second measurement result. Herein, the "first measurement result" specifically includes: a first measurement result for secondary cell 1, a first measurement result for secondary cell 2, a first measurement result for secondary cell 3; similarly, the second measurement result specifically includes: a second measurement result for serving secondary cell a, a second measurement result for serving secondary cell B. In a specific implementation, the UE may perform step 402 after the signal quality of all the secondary cells in the secondary cell list configured for the UE and the serving secondary cell of the UE are measured, or may alternatively perform step 401 and step 402, specifically, perform step 402 1 time when 1 first measurement result and 1 second measurement result are obtained. The present embodiment will be described with reference to the former as an example.

The UE determines whether the difference between the first measurement result and the second measurement result is greater than or equal to a third threshold 402.

If yes, go to step 403, otherwise, end. For example, when the first measurement result and/or the second measurement result includes a plurality of first measurement results, the determination result of step 402 is considered to be yes as long as the difference between 1 of the first measurement results and 1 of the second measurement results is greater than or equal to the third threshold. Note that, in order to keep consistent with the description in the first embodiment, in the present embodiment, the concept of the third threshold is used without referring to the first threshold.

The UE sends an activation/deactivation request message to the primary base station, the activation/deactivation request message containing information of the secondary cell requesting activation and/or deactivation. For example, it is assumed that in the present embodiment, the second measurement result for the serving secondary cell a is smaller than the second measurement result for the serving secondary cell B, the first measurement result for the secondary cell 1 is larger than the second measurement result for the serving secondary cell B, and the first measurement result for the secondary cell 2 and the measurement result for the secondary cell 3 are both smaller than the second measurement result for the serving secondary cell a. According to this assumption, the information of the secondary cell requesting activation and/or deactivation may be information requesting activation of the secondary cell 1; information requesting deactivation of the serving secondary cell a may also be requested; it is also possible to activate secondary cell 1 for the request and to request information to deactivate serving secondary cell a. In this embodiment, the information of the secondary cell requesting activation and/or deactivation is: the information "requesting activation of secondary cell 1 and deactivation of serving secondary cell a" is explained as an example. In this embodiment, the activation/deactivation request message is a MAC CE message. In specific implementation, the MAC CE message may be designed in the manner according to table 1: TABLE 1

Wherein, C0-C7 represents 8 bits, 5 bits of CO-C4 in total can be respectively corresponding to secondary cell 1, secondary cell 2, secondary cell 3, secondary cell a of monthly good service and secondary cell B of monthly good service, and "1" is used for activating the secondary cell, and "0" is used for deactivating the secondary cell; in this case, the 5 bits can be specifically expressed as: 10001. Optionally, the activation/deactivation request message may further include information of a range in which the signal quality of the measurement result is located, and it should be noted that the measurement result in this embodiment specifically includes: a first measurement result and a second measurement result. In a specific implementation, the Bit information of one or more bits in the MAC CE message may be used to indicate the range of the signal quality of the measurement result. Referring to table 2, there is an example of information indicating a range in which the signal quality of the measurement result is located with Bit information of 2 bits: TABLE 2

Bit information Signal quality (X)

00 X < A

01 A <X < B

10 B<X < C

11X > C wherein the specific value of a < B < C, A, B, C can be set according to actual needs or experience.

And 404, determining one or more secondary cells activated and/or deactivated for the UE by the main base station according to the information of the secondary cells requested to be activated and/or deactivated. Illustratively, according to the example in step 403, step 404 may specifically be: and the primary base station activates the secondary cell 1 according to the request, requests the information of deactivating the service secondary cell A, and determines one or more secondary cells activated and/or deactivated by the UE according to the conditions of the secondary cell 1, the load of the service secondary cell A and the like. The determined one or more secondary cells activated and/or deactivated for the UE may be: activating a secondary cell 1 for the UE, or: deactivating the serving secondary cell A for the UE, and may further be: secondary cell 1 is activated for the UE and the serving secondary cell eight is deactivated. In this embodiment, the determined one or more secondary cells activated and/or deactivated for the UE are: the example of activating secondary cell 1 for the UE and deactivating serving secondary cell a "is described. Optionally, the activation/deactivation request message may further include information of a range in which the signal quality of the measurement result is located, in this case, step 404 may specifically be: and the main base station determines one or more secondary cells activated and/or deactivated by the UE according to the information of the secondary cells requested to be activated and/or deactivated and the information of the range of the signal quality of the measurement result.

The primary base station updates the monthly good secondary cells of the UE according to the one or more secondary cells activated and/or deactivated for the UE 405. Illustratively, according to the example in step 404, this step 405 specifically includes: secondary cell 1 is activated and the serving secondary cell a is deactivated.

The main base station sends an activation/deactivation command to the UE, wherein the activation/deactivation command comprises information of one or more secondary cells activated and/or deactivated for the UE; the UE updates the serving secondary cell of the UE according to the information of the one or more secondary cells activated and/or deactivated for the UE. The primary base station sends an activation/deactivation command to the secondary base station managing the updated secondary cell, the activation/deactivation command containing information of one or more secondary cells activated and/or deactivated for the UE; and the secondary base station updates the serving secondary cell of the UE according to the information of the one or more secondary cells activated and/or deactivated for the UE.

Illustratively, the updated secondary cells are serving secondary cell a and secondary cell 1, as illustrated in step 404. Step 407 is specifically: the primary base station sends an activation/deactivation command to the secondary base station a, the activation/deactivation command being used to instruct the secondary base station a to activate the secondary cell 1, and sends an activation/deactivation command to the secondary base station b, the activation/deactivation command being used to instruct the secondary base station b to deactivate the serving secondary cell a.

In a specific implementation, the main base station may first execute step 406 and then execute step 407, may first execute step 407 and then execute step 406, and may also execute step 406 and step 407 at the same time.

As can be seen from the above description, before the step 401-. Optionally, before step 401, the method may include a process in which the primary base station configures a secondary cell list for the UE. Referring to fig. 5, another method for activating/deactivating a secondary cell according to an embodiment of the present invention is provided:

400.1 the primary base station sends a secondary cell configuration request message to the secondary base station in preparation for configuring dual connectivity for the UE.

Here, the "secondary base station" is generally one or more secondary base stations adjacent to the primary base station, and may include the "secondary base station managing the updated secondary cell" described in step 407 above. It should be noted that, for the sake of clarity and simplicity of fig. 5, "secondary base station" in step 400.1 and "secondary base station managing updated secondary cell" in step 407 are collectively described as "secondary base station" in fig. 5. The secondary cell configuration request message is used for requesting the secondary base station to configure the secondary cell for the UE and indicating that the configured secondary cell can be autonomously decided by the main base station to be activated. Optionally, the secondary cell configuration request message may include an identification of a secondary cell that the primary base station desires to configure for the UE.

And 400.2, the secondary base station configures one or more secondary cells for the UE according to the secondary cell configuration request message and sends a secondary cell configuration response message to the main base station. The secondary cell configuration response message may include an identifier of one or more secondary cells that the secondary base station configures for the UE and that can be autonomously determined by the primary base station to activate; in addition, when the secondary cell configuration request message includes the identity of the secondary cell that the primary base station desires to configure for the UE, the secondary cell response message may be only one piece of acknowledgement information.

400.3, the main base station sends RRC reconfiguration message to the UE after receiving the secondary cell configuration response message.

The RRC reconfiguration message includes a secondary cell list (or may also be referred to as a SCells list) and measurement configuration information, where the measurement configuration information includes information that instructs the UE to perform RRM measurement on the secondary cells in the secondary cell list configured for the UE, but does not report RRM-based measurement results to the master base station.

When the secondary cell configuration request message contains the identification of the secondary cell which the main base station expects to configure for the UE, the secondary cell list contains the secondary cell which the main base station configures for the UE. Generally, when the primary base station reconfigures the UE, the secondary cell list configured for the UE is updated accordingly, for example, when the primary base station is updated (i.e., a macro base station serving the UE is updated), the updated primary base station reconfigures the secondary cell list for the UE. In the method including step 400.3, step 401 specifically includes: and the UE carries out RRM measurement on the signal quality of the secondary cells in the secondary cell list configured for the UE according to the measurement configuration information to obtain a first measurement result based on RRM. 400.4, after the UE reconfigures according to the RRC reconfiguration message, the UE feeds back an RRC reconfiguration complete message to the main base station. It should be noted that, in a specific implementation, the UE may perform step 401 before, after, or during step 400.4, and the UE performs step 401 after performing step 400.4 is illustrated in fig. 5 as an example. In the method for activating/deactivating secondary cells provided in the embodiment of the present invention, when a difference between a first measurement result of signal quality of a secondary cell in a secondary cell list configured for a UE and a second measurement result of signal quality of a serving secondary cell of the UE is greater than or equal to a third threshold, the UE sends an activation/deactivation request message including information of the secondary cell requested to be activated and/or deactivated to a primary base station, so that the primary base station determines, according to the information of the secondary cell requested to be activated and/or deactivated, information of one or more secondary cells activated and/or deactivated by the UE, and notifies the UE and the secondary base station managing the updated secondary cell; the primary base station, the UE and the secondary base station managing the updated secondary cell update the serving secondary cell of the UE according to information of one or more secondary cells activated and/or deactivated for the UE, respectively. In the scheme, the UE can realize the updating of the service secondary cell of the UE without initiating an RA process to the secondary base station, so that compared with the prior art, the scheme can avoid the UE from accessing the unsuitable cell on one hand, and can also reduce RRC signaling overhead on the other hand.

Embodiment 2 in this embodiment, the good-service-monthly secondary cell of the UE is: a monthly good service secondary cell A, a monthly good service secondary cell B and a service secondary cell C, wherein the service secondary cell A and the service secondary cell B are secondary cells managed by the service secondary base station 1, and the service secondary cell C is a secondary cell managed by the service secondary base station 2. As shown in fig. 6, the method includes:

the serving secondary base station determines an activation/deactivation indication message for the UE 601. The activation/deactivation indication information includes indication information that the serving secondary base station no longer provides service for the UE, or indication information that the serving secondary base station no longer activates other secondary cells for the UE, or indication information that the serving secondary base station deactivates all secondary cells managed by the serving secondary base station.

The serving secondary base station sends an activation/deactivation indication message to the UE 602.

603, the UE sends an activation/deactivation request message to the main base station according to the activation/deactivation indication message.

When the activation/deactivation indication information contains the indication information that the serving secondary base station no longer provides service for the UE, the activation/deactivation request message contains the indication information that the serving secondary base station no longer provides service for the UE. Or, when the activation/deactivation indication information includes indication information that the serving secondary base station no longer activates other secondary cells for the UE, the activation/deactivation request message includes indication information that the serving secondary base station no longer activates other secondary cells for the UE. Or, when the activation/deactivation indication information includes indication information that the serving secondary base station deactivates all secondary cells managed by the serving secondary base station, the activation/deactivation request message includes indication information that the serving secondary base station deactivates all secondary cells managed by the serving secondary base station.

And 604, determining one or more secondary cells activated and/or deactivated for the UE according to the activation/deactivation request message.

For example, the one or more secondary cells determined to be activated and/or deactivated for the UE are: deactivating the information of the serving secondary cell A and the serving secondary cell B.

The primary base station updates the monthly good secondary cells of the UE based on the one or more secondary cells activated and/or deactivated for the UE 605. Illustratively, step 605 specifically includes: deactivating one or more serving secondary cells in accordance with the determined one or more secondary cells activated and/or deactivated for the UE. According to the example in step 604, step 605 specifically includes: deactivating the serving secondary cell A and the serving secondary cell B according to the determined one or more secondary cells activated and/or deactivated for the UE. It should be noted that, in this embodiment, the updating the serving secondary cell of the UE specifically includes: and updating the serving secondary cell of the UE by updating the serving secondary base station of the UE.
