1. A mobile communications system,comprising:
- a first plurality of mobile stations;
a second plurality of mobile stations different from said first plurality of mobile stations; and
a cellular communications network comprising;
a first network portion comprising a plurality of radio access cells, a second network portion comprising one or more radio access cells, and a single subscriber register configured to control network access for both said first and second plurality of mobile stations to said first and second network portions;
wherein said first plurality of mobile stations are configured to be able to register for service with said subscriber register in both said first and said second network portions, wherein said second plurality of mobile stations are configured to be able to register for service with said subscriber register in said first network portion but are prevented from registering for service with said subscriber register in said second network portion, and wherein said first plurality of mobile stations are configured to preferentially select to register for service with said second network portion rather than said first network portion.

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.

15. A method of operating a mobile communications system having a cellular communications network comprising a first network portion and a second network portion using a common radio interface protocol and a single subscriber register accessible by both network portions, a first plurality of mobile stations configured to register for normal service in both said first network portion and said second network portion, and a second plurality of mobile stations configured to register for normal service in said first network portion and prevented from registering for normal service in said second network portion, the method comprising:
-
transmitting a first network portion identity code to said second plurality of mobile stations in said first network portion;
transmitting a second network portion identity code to said first plurality of mobile stations in said second network portion; and
controlling network access for said first plurality of mobile stations and said second plurality of mobile stations to said first and second network portions with said single subscriber register, said first plurality of mobile stations preferentially selecting to register for service with said second network portion rather than said first network portion.

16. A method of operating a mobile communications system having a cellular communications network comprising a first network portion and a second network portion using a common radio interface protocol and a single subscriber register accessible by both network portions, a first plurality of mobile stations configured to register for normal service in both said first network portion and said second network portion, and a second plurality of mobile stations configured to register for normal service in said first network portion and prevented from registering for normal service in said second network portion, the method comprising:
-
transmitting a first network portion identity code to said second plurality of mobile stations in said first network portion;
transmitting a second network portion identity code to said first plurality of mobile stations in said second network portion; and
controlling network access for said first plurality of mobile stations and said second plurality of mobile stations to said first and second network portions with said single subscriber register, said first plurality of mobile stations displaying a first service indicator in response to being registered with said first network portion and a second, different, service indicator in response to being registered with said second network portion.
