Abstract
A mobile communication system in which a plurality of base stations and a plurality of core network nodes are distributed in a plurality of areas, wherein a source base station or a mobile station in a handover procedure of the mobile station transmits information for selecting a core network node to a target base station.
Claims6
A mobile station in a mobile communication system comprising a plurality of core network nodes, a source base station, and a target base station, the mobile station comprising:
- means for performing wireless communication with the source base station;
- means for performing handover from the source base station to the target base station;
- means for establishing a communication connection with the target base station which received a first identifier and a QoS information included in a handover request transmitted from the source base station,
- wherein the first identifier identifies one of the plurality of core network nodes to which the source base station is connected.
