Abstract
A mobile communications network comprises a PCN network (60-64) including a plurality of radio cells under the jurisdiction of an MSC (mobile-services switching center). One or more of said cells comprise a fixed base (60, 61) for a mobile subscriber (71). Location information regarding the fixed bases being stored in a fixed location register (FLR). When the mobile subscriber roams into such a fixed base location (60, 61) a respective service type is provided. In particular, the fixed base may be a business site (60) with a PABX network. When the mobile subscriber roams into the business site, calls involving him are routed via the PCN network or rather the base station controller (BSC) thereof, which is intelligent in that it has MSC functionality located thereat. Thus a mobile phone can act as a desk phone, with all the same services provided, whilst the mobile subscriber is within the business fixed base.
