Communication method and related equipment

Abstract

The embodiment of the present application discloses a communication method and related equipment, wherein the communication method is applied in a wireless access network system, and the wireless access network system includes a CU, at least one DU, and a GW, wherein the method includes: the GW receives a first DU The sent first interface establishment request message includes the identification of the first DU and the identification of at least one serving cell, and the at least one serving cell is managed by the first DU; the GW sends the first interface including the identification of the GW and the identification of the at least one serving cell to the CU. Two interface setup request messages; the GW receives the first interface setup response message including the identifier of at least one activated cell sent by the CU, and the at least one activated cell is included in the at least one serving cell; the GW sends a message including the at least one activated cell to the first DU The identified second interface establishes a response message. This application is adopted to reduce the signaling overhead of the CU.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and related equipment. Background technique [0002] In a fifth generation mobile communication system (5th generation mobile networks, 5G), a base station may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU). Among them, the CU and the DU are connected through the F1 interface. In the CU-DU separation scenario, the F1 interface is used to transmit signaling between the CU and the DU. In this way, an F1 interface is established between the CU and each DU that establishes a connection with it. When a CU establishes a connection with a large number of DUs, the signaling overhead of the CU will be huge. For example, the CU needs to regularly detect the operation of each DU. state, activation / deactivation of each DU leading to establishment / release of the F1 interface, etc. [0003] In this...

In this way, an F1 interface is established between the CU and each DU that establishes a connection with it. When a CU establishes a connection with a large number of DUs, the signaling overhead of the CU will be huge. For example, the CU needs to regularly detect the operation of each DU. state, the activation / deactivation of each DU leads to the establishment / release of the F1 interface, etc.
