Abstract: 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.
