System for providing interoperability of call pickup service in a proprietary enterprise communication network and a cellular communication network
First Claim
1. An interoperability system connected to an enterprise communication network and a public communication network for providing call pick up service to a user'"'"'s wireless station set which is located in the coverage area of a one of said enterprise communication network and said public communication network, and which is a member of a call pick up group comprising at least one additional station set, comprising:
- presence server means for storing user data representative a service location of a user wireless station set;
query means for exchanging said user data with at least one of said enterprise communication network and said public communication network; and
call pickup means, responsive to said user data and the presence of a call directed to said user wireless station set, for transmitting an alert signal to at least one of said additional station sets.

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.
