Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart illustrating a user residing method according to an embodiment of the present invention.
As shown in fig. 1, the user residing method includes steps S101 to S103.
Step S101, sending a capability matching message to a base station, enabling the base station to determine a base station decision based on the capability matching message and the base station capability of the base station and sending the base station decision to a core network.
When the core network needs to judge whether the terminal is supported to provide the voice and/or voice fallback service, the capability matching message can be sent to the base station, so that the base station determines a base station decision according to the capability of the base station, determines whether the base station has the capability of providing the voice and/or voice fallback service for the terminal, and sends the obtained base station decision to the core network, and the core network can conveniently determine a network decision according to the base station decision.
The base station capability of the base station includes whether the base station supports providing Voice (Voice over New Radio, 5G System Voice service) and/or Voice Fallback (EPS Fallback, Evolved Packet System Voice Fallback) service to the terminal. The base station decides whether the base station has the capability of providing voice and/or voice fallback service to the terminal.
It should be noted that the base station in this application is not necessarily a specific base station, and may be a set of base stations accessible to the terminal or a set of base stations near a cell accessed by the terminal.
In one embodiment, the user residing method further includes: and sending the capability matching message to the base station, so that the base station acquires the wireless capability information of the terminal based on the capability matching message.
In one embodiment, the capability matching message includes wireless capability information of the terminal.
The wireless capability information includes a support capability of the terminal for a voice service (VoNR), that is, whether the terminal supports the voice service.
If the core network stores the wireless capability information of the terminal, the wireless capability information of the terminal is carried when the core network sends a capability matching message to the base station; if the wireless capability information of the terminal is not stored in the core network, the base station initiates capability information query to the terminal after receiving the capability matching message sent by the core network, so as to obtain the wireless capability information of the terminal, and the base station determines a base station decision according to the capability of the base station and the wireless capability information of the terminal.
In one embodiment, sending a capability matching message to a base station, enabling the base station to determine a base station decision based on the capability matching message and a base station capability of the base station, includes: and sending a capability matching message to the base station, so that the base station determines a base station decision by utilizing the wireless capability information of the terminal and the base station capability of the base station based on the capability matching message.
After obtaining the wireless capability information of the terminal, the base station determines a base station decision by using the wireless capability information of the terminal and the base station capability of the base station based on the capability matching message sent by the core network.
In a specific implementation process, when the base station determines a decision of the base station, when the terminal supports the voice service and the base station also supports the voice service provided for the terminal, the base station considers that the base station can provide the voice service for the terminal, and when the base station supports the voice fallback service provided for the terminal, the base station considers that the base station can provide the voice fallback service for the terminal. That is, the base station may provide the voice service to the terminal only when the terminal and the base station support the voice service at the same time, and for the voice fallback service, the base station may provide the voice fallback service to the terminal as long as the base station supports the voice fallback service.
When the base station sends the base station decision to the core network, the base station decision can be fed back to the core network in the capability matching response message. In the specific implementation process, the IMS Voice Support Indicator cell in the capability matching response message may be expanded, or a dedicated cell may be newly added.
Step S102, receiving a base station decision, and determining a network decision based on the base station decision, the network configuration of the core network and the terminal configuration of the terminal.
Wherein the network decides whether the core network has the capability of providing the voice and/or voice fallback service to the terminal. After the core network receives the base station decision, the network decision can be determined according to the base station decision, the network configuration of the core network and the terminal configuration of the terminal.
In an embodiment, the base station decision comprises a first base station decision and a second base station decision. The first base station decides whether the base station has the capability of providing the voice service for the terminal, and the second base station decides whether the base station has the capability of providing the voice fallback service for the terminal.
The network decision includes a first network decision and a second network decision. The first network decision is whether the core network has the capability of providing the voice service for the terminal, and the second network decision is whether the core network has the capability of providing the voice fallback service for the terminal.
Determining a network decision based on a base station decision, a network configuration of a core network and a terminal configuration of a terminal, comprising: the first network decision is determined based on the first base station decision, and the second network decision is determined based on the second base station decision, the network configuration of the core network and the terminal configuration of the terminal.
Since the network decision includes a first network decision and a second network decision, the first network decision and the second network decision need to be determined separately when determining the network decision.
In an embodiment, determining the first network decision based on the first base station decision comprises: and if the first base station decides that the base station has the capability of providing the voice service for the terminal, determining that the core network also has the capability of providing the voice service for the terminal.
When the first base station decides that the base station has the capability of providing the voice service for the terminal, determining that the core network also has the capability of providing the voice service for the terminal; otherwise, when the first base station determines that the base station does not have the capability of providing the voice service for the terminal, it is determined that the core network does not have the capability of providing the voice service for the terminal.
That is, whether the core network has the capability of providing the voice service to the terminal or not only needs the base station to feed back that the base station has the capability of providing the voice service to the terminal.
In an embodiment, determining the second network decision based on the second base station decision, the network configuration of the core network, and the terminal configuration of the terminal includes: and if the second base station decides that the base station has the capability of providing the voice fallback service for the terminal and is configured with the N26 interface and/or the terminal has the capability of switching the attachment, determining that the core network has the capability of providing the voice fallback service for the terminal.
The network configuration of the core network comprises the N26 interface configuration of the core network, and the terminal configuration of the terminal comprises the handover attachment capability of the terminal.
And when the second base station decides that the base station has the capability of providing the voice fallback service for the terminal, determining whether an N26 interface exists in the core network, and when the N26 interface exists, determining that the core network has the capability of providing the voice fallback service for the terminal.
And when the second base station determines that the base station has the capability of providing the voice fallback service for the terminal, determining whether the terminal has the switching attachment capability, and when the terminal has the switching attachment capability, determining that the core network has the capability of providing the voice fallback service for the terminal.
And when the second base station decides that the base station has the capability of providing the voice fallback service for the terminal, if the core network does not have the N26 interface and the terminal does not have the capability of switching the attachment, determining that the core network does not have the capability of providing the voice fallback service for the terminal.
That is, whether the core network has the capability of providing the voice fallback service to the terminal, in addition to requiring the base station to feed back that the base station has the capability of providing the voice fallback service to the terminal, the core network needs to have an N26 interface or the terminal has a handover attachment capability.
Step S103, the network decision is sent to the base station and the terminal, so that the terminal determines a resident network based on the network decision, and the base station provides voice and/or voice fallback service for the terminal based on the network decision.
After obtaining the network decision, the core network sends the network decision to the base station and the terminal respectively, so that the terminal determines the resident network based on the network decision, and the base station provides voice and/or voice fallback service to the terminal.
In an embodiment, please refer to fig. 2, fig. 2 is a flowchart illustrating sub-steps of a user residing method according to an embodiment of the present invention. Step S103 includes: s1031, sending the first network decision and the second network decision to the terminal, and enabling the terminal to determine a resident network based on the first network decision and the second network decision; s1032, the second network decision is sent to the base station, so that the base station provides voice and/or voice fallback service for the terminal based on the second network decision.
For the terminal, after receiving the network decision, for the terminal with the terminal type of voice center, if the core network feedback does not support IMS voice over PS session (support the capability of voice carried over PS), that is, does not support VoNR and EPS Fallback service, the current 5G network capability is selected to be closed, and other suitable networks are selected to reside, for example, a 4G network is selected to reside. If the core network feedback supports the IMS voice over PS session, the current network can be normally resided.
For the base station, after receiving the network decision, if the core network feedback does not support the EPS Fallback, the base station attempts to provide the VoNR service to the terminal, and cannot trigger the EPS Fallback service, and the base station side also needs to consider reserving enough resources for the terminal with the terminal type of voice center to prevent the admission failure due to insufficient resources. And if the core network feedback supports the EPS Fallback, the base station tries to provide the VoNR or EPS Fallback service for the terminal.
In the user residing method provided in the above embodiment, the base station determines the base station decision based on the capability matching message and the base station capability of the base station by sending the capability matching message to the base station, and sends the base station decision to the core network, after the core network receives the base station decision, the network decision is determined based on the base station decision, the network configuration and the terminal configuration, and finally the core network sends the network decision to the base station and the terminal, so that the terminal determines the residing network based on the network decision, and the base station provides the voice and/or voice fallback service for the terminal based on the network decision, wherein the base station decision and the network decision respectively determine whether the base station and the core network have the capability of providing the voice and/or voice fallback service for the terminal. Whether the base station has the capability of providing the voice and/or voice fallback service for the terminal is inquired from the base station, whether the core network has the capability of providing the voice and/or voice fallback service for the terminal is comprehensively judged by combining network configuration and terminal configuration, so that the base station and the terminal are respectively informed, the terminal determines a resident network based on network decision, and the base station provides the voice and/or voice fallback service for the terminal based on the network decision, and the voice service can be normally carried out.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another user residing method according to an embodiment of the present invention.
As shown in fig. 3, the user dwell method includes steps S201 to 204.
Step S201, receiving a registration request sent by the terminal.
For the 5G terminal supporting IMS voice, after the terminal is started, a proper 5G cell is selected according to protocol regulations for initial access, and a registration request is sent to a core network, and after the core network receives the registration request sent by the terminal, the core network starts to judge the supporting capability of the core network for providing the voice and/or voice fallback service.
Wherein the registration request includes a service type of the terminal and a terminal configuration. The service type of the terminal includes voice priority (voice center) and data priority (data center), and in the present scheme, the service type of the terminal may be voice priority. The terminal configuration includes a Handover Attach capability (Handover Attach capability) of the terminal.
In the specific implementation process, the UE's usage setting cell may be set as "voice center" to inform the core network that the terminal needs to preferentially ensure that the voice service can be performed normally. And the 5GMM capability cell fills out whether to support the Handover Attach according to the actual capability of the terminal.
Step S202, sending a capability matching message to the base station, enabling the base station to determine a base station decision based on the capability matching message and the base station capability of the base station and sending the base station decision to a core network.
After receiving a registration request sent by a terminal, a core network sends a capability matching message to a base station so that the base station determines a base station decision according to the capability of the base station, determines whether the base station has the capability of providing voice and/or voice fallback service for the terminal, and sends the obtained base station decision to the core network.
Step S203, receiving the base station decision, and determining the network decision based on the base station decision, the network configuration of the core network and the terminal configuration of the terminal.
Step S204, the network decision is sent to the base station and the terminal, so that the terminal determines a resident network based on the network decision, and the base station provides voice and/or voice fallback service for the terminal based on the network decision.
After the network decision is obtained, the core network sends the network decision to the base station and the terminal respectively, so that the terminal determines a resident network based on the network decision, and the base station provides voice and/or voice fallback service for the terminal based on the network decision.
In an embodiment, please refer to fig. 4, where fig. 4 is a schematic flow chart illustrating a network decision sending method according to an embodiment of the present invention. The step of sending the network decision to the base station and the terminal specifically includes: s2041, sending a request response message to the terminal based on the registration request and the network decision, and informing the terminal of a second network decision of the core network; s2042, sending a context establishment request message to the base station, and informing the base station of a second network decision of the core network.
After the core network obtains the network decision, the core network sends a request response message to the terminal based on the registration request sent by the terminal so as to inform the terminal of the first network decision and the second network decision of the core network. In the specific implementation process, whether the IMS voice over PS session is supported or not may be filled in a 5GS network feature support cell in the request response message. And filling support can be carried out when the VoNR or EPS Fallback service is supported, or else, the filling support is not supported.
In addition, after obtaining the network decision, the core network sends a context establishment request message to the base station, and feeds back the second network decision, that is, the decision result of the EPS Fallback, to the base station. In the specific implementation process, the Redirection for Voice EPS Fallback cell can be multiplexed, and the dedicated cell can also be newly added.
In the user residing method provided in the above embodiment, the base station determines the base station decision based on the capability matching message and the base station capability of the base station by sending the capability matching message to the base station, and sends the base station decision to the core network, after the core network receives the base station decision, the network decision is determined based on the base station decision, the network configuration and the terminal configuration, and finally the core network sends the network decision to the base station and the terminal, so that the terminal determines the residing network based on the network decision, and the base station provides the voice and/or voice fallback service for the terminal based on the network decision, wherein the base station decision and the network decision respectively determine whether the base station and the core network have the capability of providing the voice and/or voice fallback service for the terminal. Whether the base station has the capability of providing the voice and/or voice fallback service for the terminal is inquired from the base station, whether the core network has the capability of providing the voice and/or voice fallback service for the terminal is comprehensively judged by combining network configuration and terminal configuration, so that the base station and the terminal are respectively informed, the terminal determines a resident network based on network decision, the base station provides the voice and/or voice fallback service for the terminal based on the network decision, and the terminal is provided with the voice or voice fallback service, so that the voice service can be normally carried out.
