摘要： Disclosed are a communication method and apparatus, to effectively manage a first multicast/broadcast session and improve network resource utilization. According to the method, when UE that has joined a first multicast/broadcast service and is in a radio resource control inactive state determines that an access network device changes to a first access network device, or when a terminal device determines that a cell changes to a cell of the first access network device, the terminal device may send at least one of a first message, a second message, a third message, a ninth message, or a tenth message to the first access network device. Correspondingly, the first access network device may learn, based on at least one of the first message, the second message, the third message, the ninth message, or the tenth message, that the terminal device moves to a coverage area of the first access network device to receive the first multicast/broadcast service, to effectively create a first multicast/broadcast session or update context of the first multicast/broadcast session.

摘要： This application provides a load balancing method, including: After an application network element fails to send a message related to a policy session to a source policy control network element, the application network element sends a first request message to a binding support network element, where the first request message is used to query a target policy control network element that serves the policy session, and the target policy control network element and the source policy control network element belong to a same policy control network element set. In this method, after failing to send the message related to the policy session to the source policy control network element, the application network element sends the first request message to the binding support network element. In this way, the application network element may send the message related to the policy session to the target policy control network element, to implement load balancing between policy control network elements.

摘要： A communication method and apparatus are provided, to implement combined deployment and selection of a plurality of network functions in a 5G architecture. This helps reduce deployment costs and complexity. In this application, a requesting network function sends a first network function type to a network repository function. The network repository function receives the first network function type from the requesting network function. The network repository function sends a profile of a first network function corresponding to the first network function type to the requesting network function. The requesting network function receives the profile of the first network function corresponding to the first network function type from the network repository function. The profile of the first network function includes a first indication, the first indication indicates combined deployment of the first network function and a second network function, and the first network function and the second network function have different network function types.

摘要： This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A first communication apparatus obtains service area information of a first service, where the service area information indicates a service area that supports transmission of the first service in a first transmission manner in a first network; and sends first information if a target cell of a terminal device is not in the service area, where the first information is for establishing a first transmission path, and the first transmission path is for sending data of the first service to the terminal device in a second transmission manner in the first network; or skips sending first information if a target cell is in the service area. According to the foregoing method, the first communication apparatus may determine, based on the service area information of the first service, whether the target cell is in the service area, and then perform different processing based on whether the target cell is in the service area, to facilitate sending of the data of the first service to the terminal device in an appropriate manner.

摘要： This application provides a communication method, a communications apparatus, and a communications system. The method includes: A first network element receives identity information of a terminal from a second network element, where the identity information includes an identity of the terminal or an identity of a group of the terminal; the first network element obtains, based on the identity information, type information of a serving network corresponding to the identity information; and the first network element sends application programming interface API information of the first network element based on the type information. In this method, after receiving the identity information of the terminal that is sent by the second network element, the first network element obtains the type information of the serving network corresponding to the identity information, and sends the API information or the type information of the serving network to the second network element based on the type information of the serving network, so that the second network element can select an available API based on the API information or the type information of the serving network and invoke the available API, thereby avoiding an API invoke error, ensuring an API invoke success rate, and improving user experience.

摘要： This application provides a configuration update method and apparatus. The method includes: if determining that a configuration of a terminal needs to be updated, first determining, by a mobility management network element, whether the terminal has a target service; and if determining that the terminal has the target service, sending, by the mobility management network element, a configuration update message to the terminal, and forgoing, by the mobility management network element, triggering a signaling connection release procedure. This helps avoid interrupting execution of the target service, because the signaling connection release procedure is not triggered.
