Example Embodiment

[0096] In the base station gateway, the base station gateway method for implementing base station handover, and the data processing method in the embodiment of the present invention, the RNL control signaling analysis processing module is set in the home base station gateway, which passes RANAP (RadioAccess Network Application Part, radio access network application part) Realize the function of the mobile anchor point, so that the user equipment can realize simple and fast handover of the signaling process between the home base stations under the jurisdiction of the home base station gateway.

[0097] Different from the traditional method of improving indoor coverage, the home base station is a small wireless base station placed indoors, and its access technology can be GSM, UMTS or even LTE. 3GPP is currently discussing the standardization of home base stations.

[0098] Before describing the embodiments of the present invention in detail, the multi-cell CSG scenario is first desc...

Abstract

The invention provides a base station gateway, a method of the base station gateway for realizing base station switching, and a data processing method, wherein the base station gateway comprises a storage module, an analysis module, a judgment module, a switching control module and a forwarding module, wherein the storage module stores first marks of at least two household base stations; the analysis module uses the protocol of an application part of a wireless access network to analyze a switching request message sent from a source household base station and acquire a second mark of a target household base station; the judgment module searches the storage module, judges whether the second mark is one of the first marks or not, and acquires a judging result; the switching control module interacts with the source household base station and the target household base station when the second mark is one of the first marks, and uses the protocol of the application part of the wireless access network to realize the switching from the source household base station to the target household base station; and the forwarding module forwards the switching request message to a core network when the second mark is not one of the first marks. The base station gateway of the embodiment of the invention reduces the processing pressure of the core network, and reduces the time of switching processing.

Description

technical field [0001] The present invention relates to the handover technology in UMTS (Universal Mobile Telecommunications System, namely global mobile communication system) and LTE (Long Term Evolution, long-term evolution) network, especially a kind of base station gateway, base station gateway realizes the method and data processing method of base station handover . Background technique [0002] According to statistics, nearly 70% of the traffic is generated by indoor places. From the current 2G / 2.5G network operation experience, mobile users spend 60% of their time indoors. Due to the joint influence of factors such as high data rate, long-distance transmission, and the penetration and fading of wireless signals by buildings, a good network Coverage, especially indoor coverage, is increasingly concerned by operators and manufacturers. [0003] Femtocell (femtocell base station) technology is a solution to expand the indoor coverage of mobile communications. It is sui...
