In a building, a mobile communications network 15 operates a plurality of short reach RF base stations 20-n, preferably Bluetooth, to establish communication with authorised terminals 22, 26, located in an area of interest serviced by the base stations 20-n. The network 15 connects authorized terminals, located within the area, to each other. The base stations 20-n are provided within the building and use the in-building wiring infrastructure, such a telephone lines or a LAN 25, to connect to a central data processing centre 30 having a mobility manager 34. The processing centre 30 monitors the location of authorised terminals within the building, determining whether or not they are mobile and validating their identity and associated access rights, for establishing voice, data and video communications. The processing centre 30 can also re-direct fixed line incoming communications to the appropriate mobile terminal 22, 26, as instructed, e.g. a mobile user within the building is paged about an incoming call, for example, via organiser 26 and an appropriate response is made, e.g. call sent to voicemail or to the nearest desk telephone 23. The network also enables authorized terminals to communicate with an outside communication network, e.g. a WAN, PSTN, LAN. A further invention concerning the handover of in-progress calls in a short reach network, drops calls that have been put on hold during handover if a predetermined time period has expired. |
