However, in the existing method, for the SA (Standalone, independent networking), the solution is complicated and the equipment cost is high.

本实施例的方法可以适用于在5G SA独立部署，既不支持VoNR(Voice over NR，基于NR的语音)，且不支持EPS fallback的场景。The method in this embodiment can be applied to a scenario where the 5G SA is deployed independently, neither VoNR (Voice over NR, NR-based voice) nor EPS fallback is supported.
随着3GPP 5G标准的进一步加快，5G终端的语音解决方案也越来越受到业界的重视。由于5G网络的部署方案多样：NSA(Non-Standalone，非独立部署)、SA(Standalone，独立部署)，目前3GPP定义的5G语音方案依然是沿用4G时VoLTE(Voice over LTE，基于LTE的语音)的技术路线，采取基于IMS(IP Multimedia Subsystem，IP多媒体系统)的5G语音方案，即VoNR。然而在5G部署初期，很少有运营商愿意部署VoNR，一是因为部署成本较高，难度较大，因为这涉及到了NR、NGC(5G的核心网)以及IMS系统的对接及改造。而且，5G应用在初期应该是以数据业务为核心，语音业务很难带来收入增长，因此急需一种成本较低，但又能满足5G语音业务的语音解决方案。With the further acceleration of the 3GPP 5G standard, the voice solution of 5G terminals has received more and more attention from the industry. The deployment scheme of the 5G network is diverse: NSA (Non-Standalone, non-independent deployment), SA (Standalone, independent deployment). Currently, the 5G voice scheme defined by the 3GPP is still VoLTE (Voice over LTE, LTE-based voice) when 4G is used. The technical route is based on IMS (IP Multimedia Subsystem, IP Multimedia System) 5G voice solution, namely VoNR. However, in the early stage of 5G deployment, few operators are willing to deploy VoNR. First, because of the high deployment cost, it is difficult because it involves the docking and transformation of NR, NGC (5G core network) and IMS system. Moreover, the 5G application should be based on the data service at the beginning, and the voice service is difficult to bring revenue growth. Therefore, a voice solution with low cost but satisfying the 5G voice service is urgently needed.
本发明针对5G SA独立部署，即Option2部署方式，NR-RAN(5G无线接入网)不支持VoNR，但IMS系统支持VoIMS的情况下(即IMS域支持基于IMS的语音，但5G NR接入网不支持，但同一覆盖范围4G LTE接入网支持VoLTE)，5G系统不支持到4G系统的重定向及切换流程的情况下，5G UE通过重选流程重选到4G系统上发起VoLTE通话的终端、方法与系统。The present invention is directed to a 5G SA independent deployment, that is, an Option 2 deployment mode. The NR-RAN (5G radio access network) does not support VoNR, but the IMS system supports VoIMS (ie, the IMS domain supports IMS-based voice, but 5G NR access. The network does not support, but the same coverage 4G LTE access network supports VoLTE. If the 5G system does not support the redirection and handover process of the 4G system, the 5G UE reselects to the 4G system to initiate the VoLTE call through the reselection process. Terminal, method and system.

图2为本实施例方法的一种应用场景图，当5G UE的“UE usage setting，UE使用设置”设置为“Voice centric，以语音为中心”，但在接入5G网络过程中收到网络传来的“IMSvoice over PS session not supported，不支持PS会话的IMS语音”(根据初始条件，网络不支持VoNR，也不支持EPS fallback)后，则终端设备会发现当前5G系统不支持VoNR和EPSfallback，从而自主重选到其他接入网如4G，3G以保证语音优先。FIG. 2 is a schematic diagram of an application scenario of the method according to the embodiment. When the UE usage setting of the 5G UE is set to “Voice centric, voice-centric”, but the network is received during access to the 5G network. After the "IMSvoice over PS session not supported, IMS voice does not support PS session" (the network does not support VoNR or EPS fallback according to the initial conditions), the terminal device will find that the current 5G system does not support VoNR and EPSfallback. Therefore, the independent re-election to other access networks such as 4G, 3G to ensure voice priority.
在一种示例中，5G UE在5G/4G覆盖区域下开机，在开机过程中扫描各个小区频点信息，接收小区系统消息，并选择小区驻留。正常流程，5G小区优先级大于4G小区，因此，终端设备驻留在5G小区，将该5G小区记为第一小区。In an example, the 5G UE is powered on in the 5G/4G coverage area, scans the frequency information of each cell during the boot process, receives the cell system message, and selects the cell camp. In the normal process, the 5G cell priority is greater than the 4G cell. Therefore, the terminal device resides in the 5G cell, and the 5G cell is recorded as the first cell.
其中，该系统消息包括语音指示标识和N个第二小区的频点信息。该语音指示标识用于指示所述第一小区所属的网络不支持语音呼叫业务。The system message includes a voice indication identifier and frequency point information of the N second cells. The voice indication identifier is used to indicate that the network to which the first cell belongs does not support voice call service.
例如，该语音指示标识为“IMS Voice over LTE supported duringreselection，在重选期间支持LTE的IMS语音”，即指满足前面所述前提条件的情况下，UE在附着在5G小区后会收到此业务标识，则代表5G终端设备和网络设备都支持在5G上通过重选到4G来实现VoLTE，从而进行语音业务。For example, the voice indication identifier is “IMS Voice over LTE supported during reselection, and IMS voice is supported during reselection”, that is, if the foregoing preconditions are met, the UE will receive the service after attaching to the 5G cell. The identification means that the 5G terminal equipment and the network equipment support VoLTE on the 5G by reselecting to 4G, thereby performing voice service.
S102、根据所述语音指示标识和所述N个第二小区的频点信息，对所述N个第二小区进行测量。S102. Perform measurement on the N second cells according to the voice indication identifier and the frequency information of the N second cells.
具体的，当终端设备从5G小区的系统消息读到网络带有“IMS Voice over LTEsupported during reselection”标识后，获取该5G小区不支持语音呼叫业务。Specifically, after the terminal device reads the system message of the 5G cell and the network has the IMS Voice over LTE supported during reselection identifier, the 5G cell does not support the voice call service.
这样，终端设备根据系统消息中携带的N个第二小区的频点信息，对这N个第二小区进行测量，获得这N个第二小区的测量值。In this way, the terminal device performs measurement on the N second cells according to the frequency point information of the N second cells carried in the system message, and obtains the measured values of the N second cells.
可选的，为了保证测量的准确性，则上述S102中对所述N个第二小区进行测量，包括：Optionally, in order to ensure the accuracy of the measurement, the N second cells are measured in the foregoing S102, including:
根据预设的测量周期，周期性地测量所述N个第二小区的网络信息。例如，周期性的对N个4G小区发起测量，获得N个4G小区的小区信息，如网络质量，小区ID，频点信息等。The network information of the N second cells is periodically measured according to a preset measurement period. For example, periodically, measurement is performed on N 4G cells, and cell information of N 4G cells, such as network quality, cell ID, frequency information, and the like, are obtained.
可选的，上述测量的周期可根据功耗和起呼的及时性折中，选择一个较为合理的值，如2s，即如果每2s测量一次异系统(例如4G)的小区信息，即可以省电，又可以在UE发起呼叫时准确的判断当前邻区的信号质量从而发起重选，重选成功率高。Optionally, the period of the foregoing measurement may be based on a compromise between power consumption and the timeliness of the call, and select a reasonable value, such as 2s, that is, if the cell information of the different system (for example, 4G) is measured every 2s, the province information may be saved. In addition, when the UE initiates a call, it can accurately determine the signal quality of the current neighboring cell to initiate reselection, and the reselection success rate is high.
可选的，终端设备还可以实时对N个第二小区进行测量，或者，终端设备在空闲时对N个第二小区进行测量。Optionally, the terminal device may also perform measurement on the N second cells in real time, or the terminal device performs measurement on the N second cells when idle.
S103、若检测到语音呼叫业务时，根据所述N个第二小区的测量结果，向目标小区发送重选请求，其中，所述目标小区为所述N个第二小区中的一个小区，所述重选请求用于请求接入所述目标小区。S103. If a voice call service is detected, send a reselection request to the target cell according to the measurement result of the N second cells, where the target cell is one of the N second cells, where The reselection request is used to request access to the target cell.
具体的，终端设备在5G网络下驻留后，当终端设备进行语音业务时，终端设备根据上述步骤N个第二小区的测量结果，从N个第二小区中选择一个第二小区作为目标小区。接着，向该目标小区发送重选请求，用于请求接入该目标小区，以在该目标小区内进行语音业务。这样实现在5G SA独立部署，既不支持VoNR，且不支持EPS fallback的场景下，语音业务的正常进行，进而提供了语音业务的可靠性，提高用户语音体验。Specifically, after the terminal device is camped on the 5G network, when the terminal device performs the voice service, the terminal device selects a second cell from the N second cells as the target cell according to the measurement result of the N second cells in the foregoing step. . Then, a reselection request is sent to the target cell for requesting access to the target cell to perform voice service in the target cell. In this way, the 5G SA is deployed independently, and the voice service is not supported in the scenario of the EPS fallback. The voice service is reliable and the voice experience is improved.

Frequency point information, the system of the first cell is higher than the standard of the second cell, and the voice indication identifier is used to indicate that the network to which the first cell belongs does not support voice call service; and according to the voice indication identifier And measuring, by the frequency information of the N second cells, the N second cells; if the voice call service is detected, sending a reselection to the target cell according to the measurement result of the N second cells a request, where the target cell is one of the N second cells, and the reselection request is used to request access to the target cell. In this way, the 5G SA is deployed independently, and the voice service is not supported in the scenario of the EPS fallback. The voice service is reliable and the voice experience is improved.
