Embodiment Construction

[0092] The present invention is not limited to the current so-called 3G system network, and can be applied to other network systems developed based on the 3G network architecture, as long as it meets the network architecture. However, in order to more conveniently and clearly illustrate the inventive point of the present invention, a 3G network is taken as an example below.

[0093]In the network architecture of 3G system evolution, since the eNode B and UPE are two user plane entities, when the UE is in the network attachment process or enters the active state from the idle state, it is necessary to establish a tunnel between the eNode B and the UPE to ensure that the UE Therefore, the core of the present invention lies in: using the control plane server CPS and the mobility management entity MME to perform signaling interaction, so that the eNode B and the UPE respectively obtain the address information of the other party through the CPS and the MME , so as to effectively es...

Abstract

The invention discloses a method to build and release channel in evolution network frame, wherein the network frame comprises: an evolution base station eNode B, a CPS, a MME, and a UPE. The relative method contains exactly: when UE enters activated state, eNode B interacts signaling with UPE through CPS and MME to build channel; or else when UE leaves activated state, eNode B interacts signaling with UPE through CPS and MME to cancel the channel. This invention can ensure business data transmission accurately.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a tunnel establishment and release method and device in an evolved network architecture. Background technique [0002] UMTS (Universal Mobile Telecommunications System, universal mobile communication system) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) air interface technology, and the UMTS system is usually called WCDMA communication system. The UMTS system adopts a structure similar to that of 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 realize the switching and routing functions with external networks. ...
