Abrégé
(EN) The embodiment of the invention discloses a communication method and related equipment. The communication method is applied to a wireless access network system. The wireless access network system comprises a CU, at least one DU and a GW, and the method comprises the steps that the GW receives a first interface establishment request message which is sent by a first DU and comprises an identifier ofthe first DU and an identifier of at least one serving cell, and the at least one serving cell is managed by the first DU; the GW sends a second interface establishment request message comprising theidentifier of the GW and the identifier of the at least one serving cell to the CU; the GW receives a first interface establishment response message which is sent by the CU and comprises an identifier of at least one activated cell, wherein the at least one activated cell is contained in at least one serving cell; and the GW sends a second interface establishment response message comprising the identifier of the at least one activated cell to the first DU. By adopting the method and the equipment, the signaling overhead of the CU is expected to be reduced.
(ZH) 本申请实施例公开了一种通信方法及相关设备,其中该通信方法应用于无线接入网系统中,无线接入网系统包括CU、至少一个DU和GW,其中方法包括:GW接收第一DU发送的包括第一DU的标识和至少一个服务小区的标识的第一接口建立请求消息,至少一个服务小区由第一DU管理;GW向CU发送包括GW的标识和至少一个服务小区的标识的第二接口建立请求消息;GW接收CU发送的包括至少一个激活小区的标识的第一接口建立响应消息,至少一个激活小区包含于至少一个服务小区中;GW向第一DU发送包括至少一个激活小区的标识的第二接口建立响应消息。采用本申请,以期减少CU的信令开销。
