[0172] 1. After the radio resource connection control between the UE and the CPS is established, the UE sends an attach request message to the eNode B.

[0173] 2. The eNode B forwards the UE's attach request to the CPS, and the CPS knows which eNodeB the message comes from, and thus obtains the address information of the eNode. The CPS can learn the address information of the eNodeB through two methods: learn from the signaling bearer (similar to the method learned from the underlying message above); add the IE (information element) such as the address of the eNodeB to the signaling, and after the CPS reads learn.

[0174] 3. Other processes, such as authentication and encryption, UE initiates IMS (International Mobile Subscriber Identity) registration, activates PDP context, etc., are irrelevant to the present invention and are omitted.

[0175] 4. The MME sends a RAB (radio access bearer) assignment message to the CPS, requesting to establish a radio access bearer.

Abstract

The present invention discloses a tunnel establishing and releasing method in the evolution network architecture. The said evolution network architecture is composed of some logical entities: an evolution base station eNode B, a control face server CPS, a mobile management entity MME, and a user face entity UPE. The method includes: when a user device UE is in the network attachment process or entering an activation state from an idle state, any one side of the eNode B and UPE obtains the address information of the other side; then their own address information will be sent to each other through the signaling interface, thus building the tunnel. when the UE has finished the network attachment process or entering an idle state from an activation state, any one side of the eNode B and UPE inform the other party to release the tunnel through the signaling interface between them, the other party releases the related resources after it receives the notice. Application of the present invention can effectively establish and release the data transmission tunnel to ensure the correct transmission of the business data.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for establishing and releasing a tunnel in an evolved network architecture. Background technique [0002] UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) is a third-generation mobile communication system that uses the WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) air interface technology, and the UMTS system is also commonly referred to as WCDMA communication. system. The UMTS system adopts a structure similar to the second generation mobile communication system, including a radio access network (RAN, Radio Access Network) and a core network (CN, Core Network). Among them, RAN is used to handle all wireless-related functions, while CN is used to handle all voice calls and data connections in the UMTS system, and to implement switching and routing functions ...
