Method and system for realizing direct interface between access network nodes

Abstract

The disclosure provides a method and a system for implementing a direct interface between access network nodes. The method includes: establishing, by an access network node, a direct interface with a proxy node (300); exchanging, by the access network node, information with an access network node managed by the proxy node through the established direct interface (301). By establishing a direct interface between access network nodes and performing a direct interface flow through a proxy node, the disclosure simplifies the establishment and maintenance of the direct interface on the premise that the handover speed is increased and the signaling load of a core network is decreased, thereby reducing the complexity of the establishment and maintenance of the direct interface.

Description

technical field [0001] The invention relates to communication technology between access network nodes in a wireless communication system, in particular to a method and system for realizing direct interface between access network nodes. Background technique [0002] Femtocells are small, low-power base stations that are deployed in indoor places such as homes and offices. Insufficient coverage of cellular wireless communication systems. The advantages of femtocells are affordable, convenient, low power output, plug and play, etc. [0003] In a home base station system, a home base station user is connected to a core network through a home base station access network (H(e)NB AN, Home(e)NodeB Access Network). figure 1 It is a schematic diagram of the HeNB framework structure under the LTE system, figure 2 It is a schematic diagram of the HNB framework structure under UMTS, such as figure 1 and figure 2 As shown, H(e)NBAN consists of a home base station (H(e)NB) and a hom...

AI Technical Summary

Problems solved by technology

[0007] For densely distributed base stations such as home base stations, since the number of home base stations with direct interfaces may be large and the home base stations have the characteristics of plugging and unplugging at any time, the number of direct interfaces between home base stations will become large, and their establishment and maintenance will get complicated

As a user equipment, a femtocell usually has low hardware capabilities due to cost considerations, and the establishment and maintenance of too many direct interfaces will affect the performance of the femtocell
