Abstract: The present disclosure relates to example service processing methods and devices. In one example method, a request message for setting up a Voice over Long Term Evolution (VoLTE) service for a user equipment (UE) in a packet switched (PS) domain is received by an Internet Protocol multimedia subsystem (IMS) core network device. The IMS core network device triggers a circuit switched fallback (CSFB) service of the UE after determining that the VoLTE service cannot be set up in the PS domain.

Abstract: Embodiments of the present disclosure disclose a circuit switched fallback method, a network device, and a system. The method includes: determining, by the network device, that a serving cell handover process of UE is ended; determining, by the network device, that before the serving cell handover process of the UE is ended, it has been determined that the UE needs to be moved to a second network supporting a circuit switched service; and moving, by the network device, the UE to the second network. According to the foregoing method, when CSFB triggered by a CS service initiated by UE conflicts with a serving cell handover process of the UE, the CS service of the UE can continue to be performed after completing the serving cell handover process of the UE. In this way, a success rate of establishing the CS service is increased.

Abstract: Embodiments of the present invention provide a call hold method and a terminal. The method includes: when an originating call of a terminal triggers a CS voice service, sending first indication information to an IMS sublayer by using a CC sublayer, so that the IMS sublayer detects whether an IMS voice session exists; sending signaling to a network if the IMS voice session exists, where the signaling is used to trigger a hold procedure of the INS voice session, so that the IMS voice session is in a hold state; and after the terminal completes establishment of a mobility management connection, establishing, according to second indication information, a second CS session corresponding to the IMS voice session, where the second CS session is in a hold state, thereby avoiding a case of session abnormality.
Abstract translation: 本发明的实施例提供一种呼叫保持方法和终端。 该方法包括：当终端的呼叫终端触发CS语音服务时，通过使用CC子层向IMS子层发送第一指示信息，使得IMS子层检测是否存在IMS语音会话; 如果IMS语音会话存在，则向网络发送信令，其中信令用于触发INS语音会话的保持过程，使得IMS语音会话处于保持状态; 在终端完成移动性管理连接的建立之后，根据第二指示信息，建立对应于IMS语音会话的第二CS会话，其中第二CS会话处于保持状态，从而避免会话异常的情况。

Abstract: A communication method includes sending, by a first data analytics network element, a first request to a service discovery network element. The first request requests information about a second data analytics network element. The first request includes one or more of information about distributed learning or first indication information. The information about distributed learning includes a type of distributed learning. The first indication information indicates a type of the second data analytics network element. The method also includes receiving, by the first data analytics network element, information about the second data analytics network element from the service discovery network element. The second data analytics network element supports the type of distributed learning.
