移动体通信系统
摘要：
CSG小区(闭合用户群小区：Closed Subscriber Group cell)是许可加入者利用的小区。为了接收CSG小区的服务，虽然有必要将CSG‑ID通知给移动终端，但在来自non‑CSG小区的电波未到达的状况下，无法获得服务。提供一种移动体通信系统，包含CSG小区及non‑CSG小区各自中设置的基站，使用在许可CSG小区的利用时发行的CSG‑ID，访问CSG小区，其中，CSG小区中设置的基站参照通知的移动终端的识别信息，将来自移动终端的跟踪区域更新请求发送给核心网络，核心网络判断该移动终端是否被许可利用CSG小区，在被许可时，发送许可对移动终端分配无线资源的信号和CSG‑ID。移动终端使用CSG‑ID来访问CSG小区。
摘要（英）：

A closed subscriber group (CSG) cell is a cell that allows use of subscribers. In order to receive the service by the CSG cell, a CSG-ID is required to be notified to a user equipment, which cannot be obtained in a situation outside the reach of radio waves from a non-CSG cell. In a mobile communication system including base stations respectively provided to a CSG cell and a non-CSG cell in which access is made to the CSG cell with the use of a CSG-ID issued in a case where use of the CSG cell is allowed, the base station provided in the CSG cell refers to the notified identification information of a user equipment and then transmits a tracking area update request from the user equipment to a core network, and the core network determines whether the user equipment is allowed to use the CSG cell and, in the case where the use is allowed, transmits a signal for allowing assignment of radio resources to the user equipment and the CSG-ID. The user equipment accesses the CSG cell with the use of the CSG-ID.
