A scalable, multi-protocol mobile switching center in a wireless communications network provides communications control for digital and analog wireless communications devices including devices that operate according to GSM and IS-41 standards. The hardware and software architecture of the switching center is designed so that processing that is unique to a particular protocol is performed at the lowest possible level, and remaining processing can use generic procedures. The switching center incorporates a home location register and visitor location register that are used in conjunction with software applications to determine the protocol of mobile communications devices using the wireless communications network. The mobile switching center can be used to provide a large scale distributed wireless network or a small scale wireless network. The switching center can also be used as an adjunct to a private branch exchange to provide in-building wireless services and call control. Graphical user interfaces make the wireless communications network easy to maintain.

An interface engine that is communicatively connected to a packet-switched network and to a legacy circuit-switched network uses a call processing protocol, such as the session initiation protocol (SIP), for packet-switched network communications and uses a legacy signaling protocol, such as IS-41, for legacy circuit-switched communications. In response to a registration request initiated by a subscriber device on the packet-switched network, the interface engine obtains a service profile for the subscriber from a call processing system, such as a home location register (HLR), of the legacy circuit-switched network. Service parameters derived from the service profile and stored in a service database may be used to apply services on the packet-switched network for the subscriber device.

In accordance with the principles of the present invention utilizing the BLUETOOTH specification Cordless Telephony profile, incoming calls to a cell phone including a Gateway role can be routed to another piconet device (e.g., another cell phone including a Terminal role. Two cell phones with BLUETOOTH capability each include the Cordless Telephony Profile. The cell phone receiving the call acts as a PSTN cordless telephone Gateway cell phone via the cellular network, while the other cell phone acts as a cordless telephone Terminal cell phone. The cordless telephone Terminal cell phone then acts as an extension to the Gateway cell phone allowing both calls to the Gateway cell phone to be answered at the Terminal cell phone, and even allowing calls by the Gateway cell phone to be originated by the Terminal cell phone. Moreover, the present invention includes the ability for any one of a number of authorized Terminal devices (e.g., Terminal cell phone) to answer an incoming call to a Gateway cell phone "on the fly' after hearing the ringing at the Gateway cell phone. Telephone calls may be remotely initiated from the Terminal cell phone via the Gateway cell phone. Inexpensive or featureless Terminal devices can tap into advanced features of more expensive Gateway cell phones, without the need to implement the hardware and/or software for the features themselves in the Terminal device. An authorized terminal list identifies Terminal devices authorized to answer an incoming call to a Gateway cell phone, and may be expanded to include other feature enable/disable configuration. The present invention also provides an interface between devices having differing telephony standards, e.g., between an IS-41 cell phone acting as a Terminal and a GSM cell phone acting as a Gateway cell phone.
