Mobile communication network

一个根据一个已经建立的协议(例如GSM)构造的公众移动通信网络，包括一个仅一被选择组移动台(18)可以接入的专用网络部分。该被选择组移动台(18)有一个与公众网络标识号码不同的专用网络标识号码，该专用网络部分的一个基站收发器(16，26)在其广播控制信道上广播该专用网络标识号码。一个移动交换中心(2)禁止公众用户移动台(8)经过该专用网络部分进行登录，而该专用用户移动台(18)被允许登录至整个网络。 A public mobile communications network is configured in accordance with an established protocol which includes a private network portion to which only a selected set of mobile stations have access. The selected set of mobile stations has a private network identity code which is different from a public network identity code. A base transceiver station of the private network portion broadcasts the private network identity code on its broadcast control channel. A mobile switching center prevents public subscriber mobile stations from registering via the private network portion, while the private subscriber mobile stations are allowed to register over the entire network.
