ABSTRACT:

TECHNICAL FIELD
This invention relates generally to wireless switching systems and, in particular, to telephone call management within such a system.
BACKGROUND OF THE INVENTION
In prior art business telecommunications switching systems, terminating ring groups are well known. A terminating ring group allows a group of telephones to be designated so that when one of the telephones receives an incoming call, all of the telephones in the group ring. Any of the telephones in the terminating ring group can then answer the incoming call. Upon one telephone answering the call, alerting is stopped to all of the other telephones in the terminating ring group. The prior art terminating ring groups had functioned well with wired telephone sets and wireless telephones where each wireless telephone is a second telephone set for a user. In addition, prior art terminating ring groups and their administration have functioned well for the traditional business environment where an employee is assigned a desk or a specific location and performs their principal work function at that telephone or location. The traditional environment is slowly changing. In the emerging business environment, individuals do not have a wired telephone but rather they have a wireless telephone which they carry with them at all times and which is their only telephone set. In addition, employees during the course of a day perform many functions at different locations.
SUMMARY OF THE INVENTION
The foregoing problems are solved, and a technical advance is achieved by an apparatus and method in which a wireless terminal is dynamically placed into a terminating ring group based on the location of the wireless telephone. Similarly, a wireless terminal is dynamically removed from a terminating ring group on the basis of the location of the wireless terminal. Advantageously, a wireless terminal can be excluded from joining a terminating ring group in a specific location.
Other and further aspects of the present invention will become apparent during the course of the following description and by reference to the accompanying drawing.
