Route addressing method and system, source base station, target base station and gateway

Abstract

The invention discloses a route addressing method and system, a source base station, a target base station and a gateway. The method includes the steps that obtained HeNB GW self configuration relevant information is broadcasted at the target base station HeNB in an air mode, after a user terminal UE obtains the HeNB GW self configuration relevant information, the HeNB GW self configuration relevant information is reported to the source base station through a measurement report, and after a mobile management unit MME is routed to the HeNB GW according to the HeNB GW self configuration relevant information from the source base station, addressing on the target base station HeNB is achieved. With the route addressing method and system, the source base station, the target base station and the gateway, the route addressing problem caused after the HeNB GW is introduced in can be solved so that other base stations can be routed to the HeNB base station correctly.

Description

technical field [0001] The present invention relates to the addressing technology of the wireless communication network of the fourth generation mobile communication system, in particular to a method and system for routing addressing after deploying an evolved home base station (HeNB, Home evolved NodeB) gateway (GW) in an LTE network , source base station, target base station, gateway. Background technique [0002] The X2 self-establishment process in the LTE system includes the following: [0003] 1. After detecting a new base station cell, the user terminal (UE) in the connected state will report the cell information, such as the Evolved Wireless Access System Cell Global Identity (ECGI), to the serving base station. [0004] Here, for the convenience of description, the new base station is subsequently called the target base station, and the serving base station is subsequently called the source base station. [0005] 2. According to the type of the target base station...

Problems solved by technology

For the HeNB connected to the MME through the HeNB GW, since the MME cannot obtain the configuration information of the HeNB GW itself according to the existing message flow, when the MME receives the eNB CONFIGURATIONTRANSFER request message sent by the source base station, even if the message contains the target base station ID, but because the target base station HeNB is connected to the MME through the HeNB GW, it needs to go through the HeNB GW before it can be routed to the HeNB, so when the MME cannot obtain the
