Abstract: A communication method and a communications apparatus are disclosed. The method is performed by a control plane function entity and includes: obtaining a correspondence between address information of a user plane function entity and a user plane capability supported by the user plane function entity; receiving a request message from an application server, where the request message is used to request to establish a session for a first service and includes service information of the first service, and the service information includes at least one of broadcast area information and service type information; determining address information of a target user plane function entity based on the correspondence and the service information; and establishing a session connection to the target user plane function entity based on the address information.

Abstract: Embodiments of the present invention relate to the communications field and provide a bearer setup method, apparatus, and system. The method includes: receiving, by an MME, indication information, where the indication information is used to indicate a bearer type that is set up for UE; and setting up, by the MME, a bearer for the UE according to the indication information. By means of the method, indication information used to indicate a bearer type that is set up for UE is received, and different types of bearers are set up for the UE according to the indication information, so that an MME can adjust the bearer type in real time as required and set up different types of bearers for the UE, thereby efficiently transmitting sharply fluctuated data, and lowering loss of a network and the user equipment while improving user experience.

Abstract: A data transmission method provided in embodiments of the present application includes: determining, by a mobility management entity MME, that user equipment UE changes from an unreachable state to a reachable state; sending, by the MME, a request message to a serving gateway SGW; receiving, by the MME, downlink data sent by the SGW; and sending, by the MME, the downlink data to the UE. In this way, when the UE changes to a reachable state for downlink data, the MME requests the SGW to send the downlink data, and the MME then sends the downlink data to the UE, thereby avoiding loss of the downlink data caused by delivery of the downlink data to the UE that is in an unreachable state, and improving real-time accuracy of transmission.

Abstract: The present disclosure relates to Vehicle to Everything (V2X) message communication methods and apparatus. One example method performed by a terminal includes sending a quality of service QoS request message to a network device, receiving QoS information of the terminal that is sent by the network device based on identification information of the terminal, obtaining, based on the QoS information, a QoS parameter corresponding to a message identifier of a to-be-sent V2X message, obtaining, based on the obtained QoS parameter, a radio resource used to send the to-be-sent V2X message, and sending the to-be-sent V2X message by using the obtained radio resource.

Abstract: Embodiments provide a data processing method and device. A PCRF entity obtains subscription information of remote UE, and determines a QoS rule of relay UE according to the subscription information and service QoS of the remote UE, and the PCRF entity sends the QoS rule of the relay UE to a PGW, where the QoS rule is used by the PGW to modify or establish a bearer of the relay UE, and the bearer of the relay UE is used by the relay UE to forward data of the remote UE, thereby ensuring the service QoS of the remote UE.
