Mobile communications

A base station controller (BSC) personal communications network (PCN), which can for example be based on GSM, has associated with it a local PSTN network and is such that local calls between mobile subscribers and the local PSTN network can be made without involving a remote mobile-services switching centres (MSC), thereby permitting a cheap local call tariff to be employed whilst preserving the interfaces e.g. the GSM Abis and A interfaces. The BSC is intelligent and includes a BSC function, a local MSC function and a location register which slaves mobile subscriber location information from the MSC location registers.
