ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates to the routing of calls in a communications network. In particular, this invention is directed to the updating of a subscriber's current telephone number in response to a revertive call being placed by a subscriber from a particular location.
2. Description of Related Art
Communications systems exist in which a first party may attempt to contact a system subscriber at several locations. If the subscriber cannot be reached, the system may then send a page to the subscriber's pager and wait for the subscriber to place a revertive call into the system. The system may then bridge the first party's call to the subscriber.
However, if a subscriber is consistently at different locations which may be unpredictable, the subscriber will have to constantly make revertive calls in response to pages relayed by the system instead of having the calls directly routed. Thus, there is currently no convenient method for a subscriber to update his or her location, so that repetitive revertive calls from the same location may be avoided.
SUMMARY OF THE INVENTION
A method and apparatus is provided for updating the telephone number in a subscriber's profile to the telephone number of the subscriber's current location based on a revertive call. When a revertive call is received by a system from a subscriber, the subscriber's number is identified and compared to a default number in the subscriber's profile. The call is connected and the system checks whether the telephone number is the same as the number stored in the subscriber's profile. If the subscriber's number is different than the number stored in the subscriber's profile, after the call is terminated, the system queries the subscriber as to whether the subscriber would like to have calls forwarded to his or her current telephone number for a particular length of time. If the subscriber indicates that he or she would like to have calls forwarded to his or her current telephone number for a particular period of time, the subscriber's telephone number will be stored in the subscriber's profile so that all future pages or calls will be forwarded to that number, thus obviating the need for the subscriber to constantly place revertive calls from the same location.
