Abstract
Abstract A mobile cellular communications system and method are disclosed, which limit access of private network cells only to mobile subscribers of those private networks. In cells belonging to the public network, only information about the public cells is broadcast on the public system information control channels. This public cell information is thus the only cell information that the non-subscribers' terminals are able to receive. When a mobile terminal belonging to a subscriber of one or more private networks surfaces in a public cell, the public network transmits a radio link control message to that mobile terminal, which contains information about the candidate cells for selection associated with the private network(s). The private network transmits system information via the private cell to a subscribing mobile terminal about the private and public cells' neighboring cells. Consequently, the subscribing mobile terminal will regard the public network cells and private network cells as integral parts of the overall cellular system.
