Method and system for establishing single tunnel of user plane and base station subsystem thereof

Abstract

The embodiment of the invention discloses a system for establishing a single tunnel of a user plane by a base station subsystem and a packet area network, which comprises the base station subsystem, SGSN and GGSN, wherein the base station subsystem is coupled with the SGSN of the packet area network through an enhanced control plane interface eIuPS-C of the packet area network Iu; the base station subsystem is coupled with the GGSN of the packet area network through an enhanced user plane interface eIuPS-U of the packet area network Iu; and the base station subsystem establishes the single tunnel of the user plane between the eIuPS-C interface and the GGSN. Correspondingly, the embodiment of the invention also discloses a method for establishing the single tunnel of the user plane by the base station subsystem and the packet area network, a system and a method for establishing the single tunnel of the user plane by the base station subsystem and a system architecture evolution network and the base station subsystem. The implementation of the embodiment can reduce the time delay of the user plane of the packet area network/system architecture evolution network and improve the transmission efficiency.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 200810028185.1 and the title of the invention "Method, system and base station subsystem for establishing a user plane single tunnel" submitted to the China Patent Office on May 20, 2008, the entire content of which Incorporated in this application by reference. technical field [0002] The present invention relates to the field of electronic communication, in particular to a method and system for establishing a user plane single tunnel and a base station subsystem thereof. Background technique [0003] GPRS (General Packet Radio Service, General Packet Radio Service) is a second-generation mobile communication network based on packet switching. In the third generation mobile communication system, GPRS has evolved into a UMTS PS (Universal Mobile Telecommunications System Packet Switch, Universal Mobile Telecommunications System Packet Switch) domain. Such as figure 1 ...

Problems solved by technology

[0013] The inventor finds out when realizing the present invention, as image 3 A kind of GSM / GPRS user plane protocol stack shown, because what the Gb interface user plane protocol adopts is SNDCP (Subnetwork Dependence Converge Protocol, subnetwork-related convergence protocol), and BSC does not process the user plane, the traditional GSM / GPRS network architecture and In the network system combining the packet domain network, single tunnel cannot be realized, and the same problem also exists in the network system combining the traditional GSM / GPRS network architecture and the SAE network (System Architecture Evolution, system architecture evolution)
