Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration and explanation only, not limitation. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic flow diagram of a 5G terminal during cell handover. In a 5G communication network, the first terminal 110 and the second terminal 150 are both 5G terminals and are both managed by the core network device 130.
As shown in fig. 1, the method specifically includes the following steps.
Step 101, after the first terminal 110 completes the last call service, the first terminal 110 executes a Fast return (Fast return) instruction, and returns to the 5G SA network, at this time, the first terminal 110 executes a mobility Registration procedure, and initiates a Registration Request (Registration Request) to the access network device 120.
It should be noted that, at this time, the first terminal 110 does not carry the PDU activation Request (uplink-Data-status) in the Registration Request, and does not have a Data Radio Bearer (DRB).
Step 102, the access network device 120 forwards the Registration Request to the core network device 130.
According to the specification of the protocol No. 23.502 in 3GPP, the access network device 120 does not actively create a PDU session without obtaining an indication of the first terminal 110.
It should be noted that, if the first terminal 110 desires to switch to a cell with better Signal quality, but there is no PDU session and DRB, the access network device 120 cannot perform co-channel handover on the first terminal 110, which results in increased co-channel Interference, so that the Signal to Interference plus Noise Ratio (SINR) of the first terminal 110 during moving is reduced (for example, the SINR is reduced from-9 dB to-14 dB).
In step 103, the second terminal 150 sends a call request to the second access network device 140, and wishes to establish a call service with the first terminal 110.
Step 104, the second access network device 140 forwards the call request sent by the second terminal 150 to the core network device 130.
In step 105, after obtaining the Registration Request of the first terminal 110, the core network device 130 receives the call Request sent by the second terminal 150 and forwarded by the second access network device 140. At this time, according to the description of 5.3.5.2 section in the protocol No. 38.331 in 3GPP, the core network device 130 requires to establish a PDU session with a Channel Quality Indication (CQI) of 5, but since the SINR of the first terminal 110 is reduced during the moving process and the first terminal 110 does not have the PDU session, the first terminal 110 cannot be switched to a cell with better signal Quality, and thus the first terminal 110 cannot serve as a called terminal to establish a call service with the second terminal 150. I.e. normal call flow cannot be completed (steps 106 and 107).
It should be noted that, at this time, the first terminal 110 is in the connection state, and according to the description of the reestablishment (4 a. Up requested) flow in the uplink connection state in section 4.2.3.3 of the protocol 23.502 in 3GPP and the step 12 to step 22 in the user Triggered Service Request flow (UE Triggered Service Request) in section 4.2.3.2 of the protocol 23.502. Step 12, the amf sends an N2 request to a New Radio (NR) device; in step 13, the NR device needs to complete a Radio Resource Control (RRC) reestablishment (RRC connection configuration) process, and then sends an N2 request response (request ack) message to the AMF. Steps 12 to 13 are steps 106 to 107 in the present application.
According to the requirement of the protocol 38.413, at this time, the N2 request message is a PDU session resource setup request (PDU session resource setup request), and when the NR device receives a PDU setup request issued by an Authentication Management Function (AMF) entity, the RRC reestablishment fails because there is no PDU session.
Fig. 2 is a flowchart illustrating a calling method in an embodiment of the present application, where the method is applicable to a terminal. As shown in fig. 2, the following steps are included.
Step 210, when the first terminal in the moving process is in the connected state and the first terminal does not have a protocol data unit session, changing the connected state to the idle state in response to a context release message sent by the AMF.
For example, when the first terminal is in a connected (connected) state, the first terminal moves from the first location to the second location, and the first terminal does not have a PDU session at this time, and if the signal quality of the first terminal deteriorates, the 5G SA network device cannot adjust the first terminal to a location with good signal quality because there is no PDU session resource. At this time, the context release message of the AMF is received, and the state of the first terminal can be changed from the connected state to an idle (idle) state, so that the first terminal can re-establish a connection with the network side device, thereby improving the communication quality of the first terminal.
In some specific implementations, changing the connection state to the idle state in response to a context release message sent by the authentication management function entity AMF includes: receiving a context release message sent by the AMF, wherein the context release message comprises a terminal state change identifier; and changing the connection state into the idle state according to the terminal state change identifier.
The terminal state change identifier is used for instructing the first terminal to change its connection state, for example, from a connected state to an idle state.
Step 220, determining the wake-up period of the first terminal.
For example, a time interval for retransmitting the paging message by the second terminal is obtained (for example, 2 times of paging message is transmitted in 1 second), and then the wake-up period of the first terminal may be adjusted to be 4 times of the time interval for retransmitting the paging message by the second terminal (that is, the wake-up period of the first terminal is 2 seconds), so that the first terminal can be woken up in the set period, thereby reducing the power consumption of the first terminal and prolonging the standby time.
Step 230, in response to the paging request sent by the second terminal, establishing a call connection with the second terminal according to the idle state and the wake-up period.
In some implementations, establishing a call connection with the second terminal according to an idle state and a wake-up cycle in response to a paging request sent by the second terminal includes: receiving a paging request transmitted by a second terminal and forwarded by an AMF (advanced metering framework) in an awakening period, wherein the first terminal is in an idle state; and establishing a call connection with the second terminal according to the call request, wherein the call connection comprises the PDU session and the data radio bearer.
It should be noted that, at this time, the first terminal may autonomously establish a call connection with the second terminal, which has PDU session resources, because the first terminal is in an idle state, and the call connection is established on a data radio bearer, which can ensure that a call service between the first terminal and the second terminal is successfully completed, and improve the communication quality of the first terminal.
In this embodiment, when the first terminal is in a connected state during a moving process and the first terminal does not have a protocol data unit session, the connected state is changed to an idle state in response to a context release message sent by an authentication management function entity device, so that the first terminal can establish a call connection with the second terminal according to the idle state in an awake period and complete a call service, thereby ensuring normal operation of the call service, improving a terminal call success rate in a 5G SA network, and improving user experience.
Fig. 3 is a flow chart illustrating a calling method in another embodiment of the present application. The calling method can be applied to a terminal, as shown in fig. 3, and includes the following steps.
And 310, sending a same-frequency switching report event to the AMF according to the event report identifier.
For example, when the AMF receives an intra-frequency handover report event (e.g., an A3 event), it may determine that the signal quality of a neighboring cell of the current cell is better than the signal quality of the current message, and determine that the first terminal needs to perform intra-frequency handover, that is, the neighboring cell performs communication service for the first terminal, so as to ensure that the communication service of the first terminal is performed normally.
In some specific implementations, in a case that the first terminal is in a connected state during the moving process and the first terminal does not have a protocol data unit PDU session, before the step of changing the connected state to an idle state in response to a context release message sent by an authentication management function entity AMF, the method further includes: and sending a network measurement message to the AMF according to the periodic reporting identifier, wherein the network measurement message comprises the first signal quality of the current cell and the second signal quality of the neighboring cell of the current cell, and the current cell is a cell for providing communication service for the first terminal.
It should be noted that, according to the network measurement message received regularly, the AMF may also know the first signal quality of the current cell and the second signal quality of the neighboring cell of the current cell. Through the first signal quality and the second signal quality, the communication condition of the first terminal can be monitored in real time, and better communication service is provided for the first terminal in time.
Step 320, when the first terminal in the moving process is in the connected state and the first terminal does not have the protocol data unit session, changing the connected state to the idle state in response to the context release message sent by the AMF.
Step 330, determining a wake-up period of the first terminal.
Step 340, responding to the paging request sent by the second terminal, and establishing a call connection with the second terminal according to the idle state and the wake-up cycle.
It should be noted that steps 320 to 340 in this embodiment are the same as steps 210 to 230 in the previous embodiment, and are not described again here.
In this embodiment, a same-frequency handover report event is sent to the AMF through an event report identifier; or, the network measurement message is sent to the AMF according to the periodic reporting identifier, so that the AMF can improve the communication quality of the first terminal according to the obtained related information, the first terminal can obtain better communication service, and the user experience is improved. And under the condition that the first terminal is in a connection state in the moving process and does not have a Protocol Data Unit (PDU) session, the first terminal can respond to a context release message sent by the AMF to change the connection state into an idle state, and respond to a paging request sent by the second terminal, and can establish call connection with the second terminal in an awakening period of the first terminal, thereby ensuring the normal operation of a call service and improving the call success rate of the terminal.
Fig. 4 is a flowchart illustrating a call method of a terminal in an embodiment of the present application. The method can be applied to an authentication management function entity device, as shown in fig. 4, and comprises the following steps.
Step 410, acquiring a network measurement message reported by the first terminal.
The first terminal is a terminal in a connected state in the moving process, and the first terminal is a terminal without a Protocol Data Unit (PDU) session. The network measurement message may include the signal quality of the current cell where the first terminal is located, and may also include the signal quality of neighboring cells of the current cell, so as to determine whether the signal quality obtained by the first terminal is optimal.
Step 420, in response to the same frequency handover report event sent by the first terminal, determining to send a context release message to the first terminal according to the network measurement message.
For example, when the signal quality of the neighboring cell is better than that of the current cell, the first terminal may send a same-frequency handover report event, so that the AMF knows that the first terminal wants to be able to handover to the neighboring cell with better signal quality, and at this time, the AMF sends a context release message to the first terminal, so that the first terminal changes the connection state to an idle state, so that the first terminal can establish a call connection with the second terminal in its wake-up period, and complete a call service.
In some specific implementations, determining to send a context release message to a first terminal according to a network measurement message in response to a same-frequency handover report event sent by the first terminal includes: receiving a same-frequency switching report event sent by a first terminal, wherein the same-frequency switching report event is used for representing that the first terminal expects to be switched from a current cell to an adjacent cell of the current cell; extracting a first signal quality of a current cell in the network measurement message, wherein the current cell is a cell providing communication service for the first terminal; extracting a second signal quality of the neighbor cell in the network measurement message; comparing the first signal quality with the second signal quality to obtain a comparison result; and sending a context release message to the first terminal under the condition that the comparison result is that the first signal quality is greater than the second signal quality.
For example, the threshold of the preset signal quality (for example, the preset signal carrier level is used to represent the preset signal quality) is-100 dBm, and if the first signal quality is-120 dBm, and the second signal quality is-90 dBm, the second signal quality is significantly higher than the first signal quality, and the first signal quality is lower than the preset signal quality threshold, at this time, it indicates that the current cell cannot provide a normal communication service for the first terminal, the AMF sends a context release message to the first terminal, so that the first terminal can switch its state (for example, the first terminal switches the state of the first terminal from a connected state to an idle state according to the context release message), so that the AMF performs cell switching on the first terminal, and improves the communication quality of the first terminal.
In some implementations, after determining to send a context release message to the first terminal according to the network measurement message in response to an intra-frequency handover report event sent by the first terminal, the method further includes: acquiring a Protocol Data Unit (PDU) session and a data radio bearer of a first terminal; and switching the first terminal from the current cell to an adjacent cell according to the PDU session and the data radio bearer, wherein the adjacent cell provides communication service for the first terminal, and the current cell and the adjacent cell are in the same frequency band.
It should be noted that, when the first terminal switches the state of the first terminal from the connection state to the idle state according to the context release message, if the first terminal receives the paging request sent by the second terminal in its wake-up period, the first terminal will normally establish a call connection with the second terminal, so that the first terminal has PDU session resources and data radio bearers, and when the AMF learns that the first terminal has PDU session resources and data radio bearers, the AMF can quickly switch the first terminal from the current cell to the neighboring cell, and the neighboring cell provides communication service for the first terminal, so as to improve the communication quality of the first terminal. And the current cell and the adjacent cell are in the same frequency band.
In this embodiment, a network measurement message reported by a first terminal is obtained; responding to a same-frequency switching report event sent by a first terminal, determining to send a context release message to the first terminal according to a network measurement message so as to enable the first terminal to change a connection state into an idle state, completing a calling service with a second terminal according to the idle state and an awakening period of the first terminal, ensuring normal operation of the calling service between the first terminal and the second terminal, improving the calling success rate of the terminal, switching the first terminal from a current cell to an adjacent cell according to PDU (protocol data unit) conversation and data radio bearer, and providing communication service for the first terminal by the adjacent cell so as to improve the service quality of the first terminal and improve user experience.
Fig. 5 shows a block diagram of the terminal in the embodiment of the present application. As shown in fig. 5, the terminal specifically includes: an updating module 501, configured to, when a first terminal in a moving process is in a connected state and the first terminal does not have a protocol data unit PDU session, change the connected state to an idle state in response to a context release message sent by an authentication management function entity AMF; a wake-up period determining module 502, configured to determine a wake-up period of the first terminal; a call connection establishing module 503, configured to respond to a paging request sent by the second terminal, and establish a call connection with the second terminal according to the idle state and the wake-up period.

Fig. 7 shows a block diagram of the components of the call system in the embodiment of the present application. As shown in fig. 7, includes: 5G terminal 710, 5G access network device 720, 5G core network device 730. The core network device 730 includes: authentication management function entity device 731. The Access Network device 720 may be AN Access Network (AN) device, and the authentication management function entity device 731 may be AN AMF.
Fig. 8 is a flowchart illustrating a working method of the call system in the embodiment of the present application, and as shown in fig. 8, the method specifically includes the following steps.
After the terminal 710 of step 801,5G completes the last call service, the 5G terminal 710 executes a Fast return (Fast return) instruction to return to the 5G SA network. At this time, the 5G terminal 710 performs a mobility registration procedure, and initiates a registration request to the 5G access network device 720.
It should be noted that, at this time, the 5G terminal 710 does not carry the PDU activation request information in the registration request, and does not have a DRB.
Step 802,5G the access network device 720 forwards the registration request sent by the 5G terminal 710 to the 5G core network device 730.
Step 803,5G the core network device 730 receives the registration request from the 5G terminal 710 and receives the call request from the calling terminal.
It should be noted that the calling terminal also forwards the call request sent by the calling terminal through the 5G access network device 720, so that the 5G terminal 710 can establish a call service with the calling terminal.
Step 804,5G reports the identifier according to a preset period, and sends a network measurement message to the AMF731 in the 5G core network device 730 through the 5G access network device 720.
The network measurement message includes a first signal quality of a current cell where the 5G terminal 710 is located and a second signal quality of a neighboring cell of the current cell.
Step 805,5G, the terminal 710 sends a co-frequency handover report event to the AMF731 according to the preset event report identifier, so that the AMF731 determines whether the 5G terminal 710 needs to perform co-frequency handover.
The same-frequency handover reporting event may be an event of a same-frequency system, or an event between two systems using different frequency bands, for example, an A3 event, where the signal quality of the neighboring cell is better than that of the current cell.
Step 806, the amf731 extracts a first signal quality of the current cell and a second signal quality of the neighboring cell from the received network measurement message, and compares the first signal quality and the second signal quality to know that the signal quality of the neighboring cell is better than the signal quality of the current cell; meanwhile, the AMF731 also receives an A3 event reported by the 5G terminal 710, and it can be known from the A3 event that the 5G terminal 710 wants to be able to switch to a neighboring cell with better signal quality to operate.
In some implementations, to ensure the communication quality of the 5G terminal 710, the AMF731 issues a handover command to handover the 5G terminal 710 from the current cell to the neighboring cell.
In step 807, the amf731 sends a context release message to the 5G access network device 720, so that the 5G access network device 720 forwards the context release message to the 5G terminal 710, and at the same time forwards the call request initiated by the calling terminal, which is received in step 803, to the 5G terminal 710, so that the 5G terminal 710 can establish a call connection with the calling terminal.
The context release message includes a terminal state change identifier, so that the 5G terminal 710 can change its own state, which is beneficial to completing subsequent call services.
Step 808,5G terminal 710 changes its state from connected (connected) to idle (idle) according to the terminal state change identifier in the context release message.
Step 809,5G the terminal 710 starts a paging procedure, that is, within the wake-up period, in response to the call request initiated by the calling terminal received in step 807, a call connection is established with the calling terminal to complete the call service.
Wherein the call connection includes a PDU session and a DRB.
In this embodiment, when the first terminal is in a connected state during moving and the first terminal does not have a PDU session, the state of the 5G terminal is changed by receiving a context release message sent by the AMF, so as to avoid that the 5G terminal is dragged to death in the current cell and cannot be switched to a neighboring cell with better signal quality due to no PDU session and DRB, and thus the call request of the calling terminal cannot be responded, resulting in a call failure. When the state of the 5G terminal is changed from the connection state to the idle state, the 5G terminal can establish call connection with the calling terminal according to the idle state in the awakening period, and complete the call service, so that the normal operation of the call service is ensured, the terminal call success rate under the 5G SA network is improved, and the user experience degree is improved.
It is to be understood that the above embodiments are merely exemplary embodiments that are employed to illustrate the principles of the present application, and that the present application is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the application, and these changes and modifications are to be considered as the scope of the application.
