<p>A method for establishing an A interface user plane calling based on Internet Protocol (IP) bearing, includes: when the calling is established between Base Station Subsystem (BSS) and core network, Mobile Switching Centre Server (MSC Server) in the core network communicates with BSS and Media Gateway (MGW) in the core network respectively. When MSC Server obtains IP Transport Layer Information of one of the BSS and MGW, the information is sent to another. When both BSS and MGW obtain IP Transport Layer Information of the opposing side, it is completed to establish the A interface user plane linking. The invention realizes to exchange IP Transport Layer Information of user plane devices, and completes to establish the A interface user plane linking when the calling establishing is completed via interactive message of control plane.</p> |
