Embodiment Construction

[0028] The basic idea of ​​the present invention is to introduce a direct interaction interface between the wireless access nodes of the 2G system and the wireless access nodes of the 4G system, for example, the interface between eNodeB and BSC, which is called IUR-Y in this paper Interface, through this new interface, the interoperable signaling interaction between the 2G system and the 4G system can be simplified as Figure 4 shown. The interoperability between the 4G system and the 2G system can be completed directly through the new interface (IUR-Y), which reduces the signaling interaction between the RAN and the CN, and reduces the signaling load of the radio access network and the core network; at the same time, it also It shortens the interoperability delay between systems, improves the success rate of interoperability, and enhances user experience.

[0029] In order to make the technical principles, features and technical effects of the technical solution of the prese...

Abstract

The invention provides a base station controller (BSC). The BSC possesses a first interface used to carry out information interaction with an evolution base station (eNB) of a long-term evolution (LTE) system. The invention also provides the evolution base station (eNB). The eNB possesses a second interface used to carry out information interaction with a BSC of a second generation of wireless communication system. According to the invention, through introducing a new interface between the BSC and the eNB, interoperation of the LTE and a 2G system can be performed directly through the new interface. Through the interface, high-efficient interaction of correlation information between the two systems is realized. Simultaneously, a data processing load generated to a core network is reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a device for realizing interaction between a 2G access network and a 4G access network. Background technique [0002] At present, 3GPP radio access network has multiple standards, such as 4G access network represented by E-UTRAN (Evolved Universal Terrestrial Radio Access Network) and GSM / EDGE wireless access network The 2G access network represented by GSM EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network) exists at the same time, providing wireless access services for user equipment (UE). [0003] figure 1 Shown is a schematic diagram of a network architecture in which E-UTRAN and GERAN coexist. The wireless access node in E-UTRAN is a base station (eNodeB), and the wireless access node in GERAN is a base station controller BSC. Among them, there is an X2 interface between eNodeBs in the E-UTRAN, which is used for signaling interaction and ...
