Abstract: A method and system for measuring a service transmission status of a user equipment is provided. A first service station transmits a first data packet for a user equipment; the first service station determines at least one second service station that transmits a second data packet for the user equipment; and the first service station instructs the at least one second service station to measure a service transmission status of the user equipment, where the first data packet and the second data packet are different data packets of a same service of the user equipment or data packets of different services. According to the method and system, a service transmission status of a user equipment can be measured in a multi-station transmission scenario.

Abstract: A handover method, an access network device, and a terminal device are provided. A handover method comprising: receiving by an access network device, a change instruction message, wherein the change instruction message is used to instruct the access network device to instruct a terminal device to perform an update, generating, by the access network device, an update message, wherein the update message is used to instruct the terminal device to perform an update; and sending by the access network device, the update message to the terminal device. Based on a handover procedure initiated by the second core network device, the connection between the terminal device and the second core network device may be switched to the connection between the terminal device and the first core network device without switching of the access network device, so that a network communication requirement is efficiently met.

Abstract: This application provides a communication method and a communications apparatus. A terminal in an inactive state receives a paging message, and content in the paging message is determined. When the content includes a first identity of the terminal, the terminal sends a first request message to a first access network device, where the first request message carries a non-access stratum (NAS) identifier of the terminal. When the content includes a second identity of the terminal and an identity of an anchor access network device, the terminal sends a second request message to the first access network device. The second identity of the terminal identifies the terminal on the anchor access network device, and the identity of the anchor access network device identifies the anchor access network device in an access network. The communication method of is application can adapt to a communication requirement of a terminal in an inactive state.

Abstract: The present invention discloses a method and device for maintaining service continuity. The method for maintaining service continuity includes: receiving, by a base station, a first notification, which is sent by an MCE, for stopping scheduling of an MBMS service; and notifying, by the base station, user equipment of MBMS service scheduling stop information, and continuing to schedule the MBMS service. In this way, a service interruption time that is caused when UE receives a service after an MCE stops scheduling of the service can be effectively reduced.

Abstract: The present disclosure relates to a cell multicast service processing method and a device. The method may include receiving, by a first base station, a multicast service session start message sent by a multicast coordination entity. The method may also include sending, by the first base station, a multicast service session start failure message or a multicast service session start response message to the MCE, where the multicast service session start failure message indicates that a multicast service fails to be started for all the cells that are managed by the first base station and for which a multicast service session is to be started, and the multicast service session start response message includes an identifier of a cell for which a multicast service is successfully started among the cells that are managed by the first base station and for which a multicast service session is to be started.
