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.

Claims

1. A core network node in a mobile communication system comprising a target base station, a source base station, and a mobile station, the core network node comprising:

a unit which receives a first identifier from the target base station when the mobile station performs handover from the source base station to the target base station;

wherein the first identifier identifies the core network node to which the source base station is connected.

2. The core network node according to claim 1, wherein the first identifier is included in a message related to Path Switch.

3. A target base station in a mobile communication system comprising a source base station, a core network node, and a mobile station, the target base station comprising:

a unit which transmits a first identifier to the core network node when the mobile station performs handover from the source base station to the target base station;

wherein the first identifier identifies the core network node to which the source base station is connected.

4. The target base station according to claim 3, wherein the first identifier is included in a message related to Path Switch.
