Abstract: This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. A service level agreement (SLA) level may be obtained based on user information of a terminal, and further a user plane (UP) device corresponding to the terminal is determined based on the SLA level of the terminal. Thus, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.

Abstract: The present disclosure discloses example downlink buffer status feedback methods and apparatuses. One example method includes determining first information by a first node, where the first information indicates a downlink buffer status of a first bearer between the first node and a parent node of the first node. The first information is sent by the first node to a second node, where the first node is a relay node in a wireless relay communications system, and the second node is a parent node of the first node.

Abstract: This application provides example communication methods and example communications apparatuses, to implement bearer mapping for user data transmission. One example method is applied to a wireless backhaul system having a first network and a second network of different RATs. The example method includes obtaining, by a first management network element in the wireless backhaul system, information about a first radio bearer of a terminal in the first network, where the information about the first radio bearer is used to indicate the first radio bearer. The first management network element can then determine a mapping relationship between the first radio bearer and a second radio bearer based on the information about the first radio bearer, where the second radio bearer is a radio bearer of the first device in the second network.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
