[0046] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0047] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0049] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0050] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0051] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] As mentioned above, under the mechanism where the terminal can only obtain whether the 5G network supports voice services but cannot perceive the voice solutions supported by the 5G network, if the 5G terminal temporarily enters a specific environment where the 4G signal is poor but the 5G signal is good, the E-UTRAN will be disabled for 12 minutes and the 5G network will be notified. Even if the terminal has moved to an environment with a good 4G signal within 12 minutes, the terminal will not be able to fall back to 4G within 12 minutes. If the network or terminal can only use the EPS Fallback solution, the terminal will not be able to initiate calls within 12 minutes.

[0053] Moreover, with the development of VoNR in the future, EPS Fallback will be phased out. At this time, if the terminal cannot perceive the network capability, it will cause technical problems that the terminal that does not support VoNR cannot use audio and video services.

[0054] In response to the above technical problems, the present disclosure proposes a technical solution for delivering 5G voice capabilities, in which NR can automatically notify the AMF entity of the 5G voice capabilities it supports, or the AMF entity configures the 5G voice capabilities supported by NR; when the AMF entity registers a 5G user, in the registration accept message returned to the terminal, the parameters of the 5GS network feature support message are extended according to the 5G voice capabilities of NR, and the 5G voice capabilities supported by the network are delivered to the terminal.

[0055] In this way, the terminal can determine the voice solution and optimize the audio and video service processing mechanism according to the voice capability of the network. Thus, the technical problem of being unable to make calls for 12 minutes when the terminal E-UTRAN is disabled is solved; the connection rate of 5G audio and video services is improved to meet the real-time communication needs of 5G users. For example, the technical solution of the present disclosure can be implemented through the following embodiments.

[0056] Figure 1a A flow chart showing some embodiments of the voice communication method of the present disclosure.

[0057] like Figure 1aAs shown, in step 110a, the AMF entity determines the voice capability information of the NR, where the voice capability information is used to indicate whether the NR supports at least one of VoNR or EPS.

[0058] In some embodiments, the AMF entity receives voice capability information sent by NR; the AMF entity updates and stores the voice capability information corresponding to NR.

[0059] In some embodiments, the AMF entity receives an access network configuration update (RAN CONFIGURATION UPDATE) message sent by the NR, and the access network configuration update message includes voice capability information. For example, the access network configuration update message is generated according to the update of the voice capability switch setting in the NR, and the voice capability information is included in the voice capability parameter added to the access network configuration update message, and the voice capability switch setting includes a support switch setting for at least one of VoNR or EPS.

[0060] In some embodiments, the VoNR and EPS Fallback switch settings related to voice capabilities in NR are updated. For example, NR determines the network 5G voice solution through switch settings, and the switch change parameter values ​​of NR may include: 11 indicates that both VoNR and EPS Fallback are supported; 01 indicates that only EPS Fallback is supported; 10 indicates that only VoNR is supported; 00 indicates that neither VoNR nor EPS Fallback is supported; the AMF entity responds successfully and updates the voice capabilities corresponding to the stored NR.

[0061] In some embodiments, the NR voice capability transfer module updates the NR voice capability to the AMF entity by extending the parameter Voice Capability in the RAN CONFIGURATION UPDATE message. For example, the newly added parameter VoiceCapability value is as follows: 11 indicates that both VoNR and EPS Fallback are supported; 01 indicates that only EPS Fallback is supported; 10 indicates that only VoNR is supported; 00 indicates that neither VoNR nor EPS Fallback is supported; the AMF entity responds successfully and updates the voice capability corresponding to the stored NR.

[0062] In some embodiments, the AMF entity configures voice capability information for NR based on the 5G network conditions.

[0063] For example, the voice capability of NR can also be determined by configuration. A new NR voice capability configuration function is added in the AMF entity, which can be configured for a single NR or set as a default value based on the 5G network situation. For example, at this stage, it is set to support EPS Fallback by default. After all NRs in the entire network support VoNR, it will be set to support VoNR and EPS Fallback by default.

[0064] In step 120a, when the terminal initiates a registration request to the NR, the AMF entity sends voice capability information to the terminal so that the terminal performs voice communication according to the voice capability information.

[0065] In some embodiments, the AMF entity extends the 5G system network feature support parameter (5GS network feature support) in the registration reception message according to the voice capability information; the AMF entity sends the extended registration reception message to the terminal.

[0066] For example, the voice capability transfer module of the AMF entity extends the 5GS network feature support parameter according to the 5G voice capability of NR in registration accept, and transfers the 5G voice capability supported by the network to the terminal; the terminal stores the 5G network voice capability.

[0067] Figure 1b Flowcharts showing other embodiments of the voice communication method of the present disclosure.

[0068] like Figure 1b As shown, in step 110b, the terminal determines the support status of NR for at least one of VoNR or EPS based on the voice capability information of NR sent by the AMF entity.

[0069] In some embodiments, the terminal determines whether the NR supports EPS fallback; if the NR supports EPS fallback, the terminal determines whether the E-UTRAN is in a deactivated state.

[0070] For example, when a user initiates a call, the voice optimization module of the terminal checks that the 5G network voice capability only supports EPSFallback; if it determines that the terminal is in E-UTRAN disable state, it automatically enables E-UTRAN.

[0071] In step 120b, the terminal communicates according to the determination result.

[0072] In some embodiments, when NR does not support EPS fallback, the terminal falls back to the E-UTRAN or CS domain for communication; when NR supports EPS fallback and E-UTRAN is in a disabled state, E-UTRAN is enabled for communication.

[0073] In some embodiments, the terminal sends a registration request to the NR to notify the NR to enable E-UTRAN for communication.

[0074] For example, the status is updated to RAN, and S1 mode is set to supported in the 5GMM (5GS mobility management) capability parameter, indicating that the terminal supports 4G network and letting the network know that the terminal has enabled E-UTRAN.

[0075] In this way, the EPS fallback can be guaranteed to be successful, thereby ensuring that the calling party or the called party will not be unable to connect due to the EPS fallback failure.

[0076] In some embodiments, when a user initiates a call, the terminal initiates a call request to a P-CSCF entity or a BAC. For example, the terminal initiates a call request INVITE to the P-CSCF entity or the BAC.

[0077] In the above embodiment, NR automatically updates its voice capability to 5GC, and can transmit the 5G voice capability supported by the network to the terminal; the terminal optimizes the processing mechanism according to the voice capability of the network to improve the connection rate of 5G audio and video services.

[0078] Figure 2a A signaling diagram showing some embodiments of the voice communication method of the present disclosure.

[0079] like Figure 2a As shown, in event 1, the VoNR and EPS Fallback switch settings related to voice capabilities in NR are updated.

[0080] In event 2, the NR voice capability delivery module updates the NR voice capability to the AMF entity by extending the parameter Voice Capability in the RAN CONFIGURATION UPDATE. For example, the newly added parameter Voice Capability value is as follows: 11 indicates that both VoNR and EPS Fallback are supported; 01 indicates that only EPS Fallback is supported; 10 indicates that only VoNR is supported; 00 indicates that neither VoNR nor EPS Fallback is supported.

[0081] In event 3, the AMF entity responds successfully and updates the voice capabilities corresponding to the stored NR.

[0082] For example, NR voice capability can also be configured by adding NR voice capability configuration function in AMF entity. It can be configured for a single NR, or the default value can be set according to the 5G network situation. For example, at the current stage, it is set to support EPSFallback by default; after all NRs in the network support VoNR, it is set to support VoNR and EPS Fallback by default.

[0083] In some embodiments, the voice capability delivery module of the AMF entity extends the 5GS network feature support parameter according to the 5G voice capability of NR in registration accept, and delivers the 5G voice capability supported by the network to the terminal; the terminal stores the 5G network voice capability.

[0084] For example, the 5GS network feature support parameter extension is as follows Figure 2b shown.

[0085] Figure 2b Schematic diagrams showing some embodiments of the voice communication method of the present disclosure.

[0086] like Figure 2b As shown in FIG. 1 , VoNR and EPS Fallback are newly added fields, and a value of 1 indicates that they are not supported, and a value of 0 indicates that they are not supported. For example, VoNR and EPS Fallback can be set in octet 4 (the fourth octet).

[0087] Figure 3a A signaling diagram showing some embodiments of the calling communication flow of the present disclosure.

[0088] like Figure 3a As shown, in event 1, the user initiates a call.

[0089] In event 2, the terminal voice optimization module checks the 5G network voice capability to only support EPS Fallback. If the terminal does not support EPS Fallback, the terminal returns to the E-UTRAN or CS domain; if the terminal supports EPS Fallback, it enters event 3.

[0090] In event 3-4, if it is determined that the terminal is in E-UTRAN disable state, E-UTRAN is automatically enabled.

[0091] In event 5, the status is updated to the RAN and the S1mode in the 5GMM capability is set to supported.

[0092] In event 6, the terminal initiates a call request INVITE to the P-CSCF entity or BAC.

[0093] Figure 3b A signaling diagram showing some embodiments of the called party communication flow of the present disclosure.

[0094] like Figure 3b As shown, in event 1, the terminal receives a called request INVITE sent by the P-CSCF entity or the BAC.

[0095] In event 2, the terminal voice optimization module checks the 5G network voice capability to only support EPS Fallback. If the terminal does not support EPS Fallback, the terminal returns to the E-UTRAN or CS domain; if the terminal supports EPS Fallback, it enters event 3.

[0096] In event 3-4, if it is determined that the terminal is in E-UTRAN disable state, E-UTRAN is automatically enabled.

[0097] In event 5, the status is updated to the RAN and the S1mode in the 5GMM capability is set to supported.

[0098] In the above embodiment, a voice capability delivery module is added in NR to update its voice capability to AMF according to the VoNR and EPS Fallback switch settings.

[0099] Add a voice capability delivery module in the AMF entity to configure the voice capabilities of the relevant NR; when the 5G user registration returns registration accept to the terminal, according to the 5G voice capability of NR, expand the 5G network message parameter 5GS networkfeature support and expand the parameters in 5GS network feature support to carry the 5G voice solution; deliver the 5G voice capabilities supported by the network to the terminal;

[0100] A new voice capability optimization module is added to the terminal. According to the voice capability optimization processing mechanism of the network, the problem of being unable to make calls for 12 minutes when the terminal E-UTRAN is disabled is solved, thereby improving the connection rate of 5G audio and video services.

[0101] When the terminal temporarily enters a specific environment where the 4G signal is poor but the 5G signal is good, E-UTRAN is disabled for 12 minutes and the 5G network is notified; if the network or the terminal only supports EPS Fallback, the terminal automatically enables E-UTRAN when initiating or receiving a call request INVITE, notifies NR, and sets the S1 mode in the 5GMM capability IE to support.

[0102] If the network only supports VoNR and the terminal only supports EPS Fallback, the terminal will fall back to the E-UTRAN or CS domain when voice demand occurs.

[0105] In some embodiments, the voice communication device 4a further includes: a receiving unit 43a, configured to receive voice capability information sent by NR; wherein the determining unit 41a updates and stores the voice capability information corresponding to NR.

[0106] In some embodiments, the receiving unit 43a receives an access network setting update message sent by the NR, where the access network setting update message includes voice capability information.

[0107] In some embodiments, an access network setting update message is generated based on an update of a voice capability switch setting in NR, the voice capability information is included in a voice capability parameter added to the access network setting update message, and the voice capability switch setting includes a support switch setting for at least one of VoNR or EPS.

[0108] In some embodiments, the receiving unit 43a configures voice capability information for NR according to the 5G network conditions.

[0109] In some embodiments, the sending unit 42a extends the 5G system network feature support parameters in the registration reception message according to the voice capability information, and sends the extended registration reception message to the terminal.

[0112] In some embodiments, the determination unit 41b determines whether the NR supports EPS fallback; if the NR supports EPS fallback, determines whether the E-UTRAN is in a deactivated state.

[0113] In some embodiments, when NR does not support EPS fallback, the communication unit 42b falls back to the E-UTRAN or CS domain for communication; when NR supports EPS fallback and E-UTRAN is in a disabled state, E-UTRAN is enabled for communication.

[0114] In some embodiments, the communication unit 42b sends a registration request to the NR, informing the NR to enable E-UTRAN for communication.
