A mobile cellular communications system and method are disclosed, which limit access to private network cells (114) only to mobile terminals that are used by subscribers to those private networks. In cells belonging to the public network, only information about the public cells (122) is broadcast on the public system information control channels. This public cell (122) information is thus the only cell information that the non-subscribers' mobile terminals are able to receive. When a mobile terminal belonging to a subscriber of one or more private networks surfaces in a public cell (122), 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) involved. The private network transmits system information via the private cell (114) to a subscribing mobile terminal about the private and public cells' neighboring cells (122). Consequently, the subscribing mobile terminal will regard the public network cells (122) and private network cells (114) as integral parts of the overall cellular system. Cells associated with private networks to which that mobile terminal's end user is a "non-subscriber" are thus "invisible" to that mobile terminal.
