Patent ID: 8364158

Claim:
A method for cell update comprising: when an User Equipment (UE) which is in a connected state in a cell under jurisdiction of a Source Radio Network Controller (SRNC) initiates a cell update to a cell under jurisdiction of a target home NodeB; the target home NodeB receiving cell update signaling sent by the UE; the target home NodeB sending signaling carrying cell update information to the SRNC through a home NodeB gateway; the target home NodeB receiving signaling carrying UE Context returned by the SRNC; and the target home NodeB allocating corresponding radio resources to the UE and sending a cell update confirmation message to the UE; or when an UE which is in a connected state in a cell under jurisdiction of a Source home NodeB initiates a cell update to a cell under jurisdiction of a target Radio Network Controller (TRNC); the TRNC receiving cell update signaling sent by the UE; the TRNC sending signaling carrying cell update information to the Source home NodeB through a home NodeB gateway; the TRNC receiving signaling carrying UE Context returned by the Source home NodeB; and the TRNC allocating corresponding radio resources to the UE and sending a cell update confirmation message to the UE; or when an UE which is in a connected state in a cell under jurisdiction of a Source home NodeB initiates a cell update to a cell which is under jurisdiction of a target home NodeB; the target home NodeB receiving cell update signaling sent by the UE; the target home NodeB sending signaling carrying cell update information to a source home NodeB through a home NodeB gateway; the target home NodeB receiving signaling carrying UE Context returned by the source home NodeB; and the target home NodeB allocating corresponding radio resources to the UE and sending a cell update confirmation message to the UE; wherein the target home NodeB sending the signaling carrying the cell update information to the source home NodeB through the home NodeB gateway comprises: when the target home NodeB and the source home NodeB belong to different home NodeB gateways, the target home NodeB sending the signaling carrying the cell update information to a home NodeB gateway to which the source home NodeB belongs through a home NodeB gateway to which the target home NodeB belongs, and the home NodeB gateway to which the source home NodeB belongs sending the signaling carrying the cell update information to the source home NodeB; or when the target home NodeB and the source home NodeB belong to the same home NodeB gateway, the target home NodeB sending the signaling carrying the cell update information to the source home NodeB through a home NodeB gateway to which the target home NodeB belongs; wherein a communication between the home NodeB gateways, or between the TRNC and the home NodeB gateway, or between the SRNC and the home NodeB gateway, is implemented via an interface established therebetween or the core network, the interface is an Asynchronous Transfer Mode (ATM) or IP transmission protocol architecture based interface.
