BASE STATION AND METHOD IN MOBILE COMMUNICATION SYSTEM

摘要

The disclosed base station is provided with wireless communication units (82, 85) which perform wireless communication with a mobile device capable of communicating with both a first and a second mobile communication system, and network communication units (83, 84) which communicate with a switching station which manages the movement of the mobile device. If a line configuration command signal (Initial Context Setup Request) received from the switching station by a network communication unit is not the initial access to the switching station by the mobile device, then, after a line configuration response signal (Initial Context Setup Response) is transmitted to the switching station by the network communication unit, the wireless communication unit receives from the mobile device mobile device capability information (UE-UTRA-Capability) in the second mobile communication system.
