Abstract
The present interoperability system serves to pass presence and supervision information relating to a user's wireless station set between a cellular communication network and an enterprise communication network. The interoperability system functions to extend the services, such as call pick up, provided in the enterprise communication network to the cellular communication network based on the presence and supervision data provided by the interoperability system. The provision of ubiquitous call pick up service is accomplished by transmitting alert signals not only to the user's telephone line in the enterprise communication network to alert members of the call pick up group proximate to the user's office, but also to the user's wireless station set operating in the service area of the cellular communication network as well as members of the call pick up group also operating in the service area of the cellular communication network.
