Abstract
An apparatus and method in a telephone communications system that provide for redirecting a call by an adjunct processor, utilizing a control message. The control message contains various directives for current or subsequent execution by a telephone switching center, which can assume a function of a mobile switching center in a wireless communications system or a landline switching center in a landline telephone system. Directives in the control message instruct the telephone switching center to redirect a call contingent upon subsequent call events that can occur.
Claims19
A telephone communications system, said communications system supporting a call with a telephone unit, said telephone communications system including an adjunct processor connected to a telephone switching center, said telephone communications system comprising:
- means for said adjunct processor to instruct said telephone switching center to conditionally redirect said call if one of a plurality of call event types subsequently occurs, each call event type associated with a designated telephone number;
- means, responsive to said instructing means, for detecting a subsequent occurrence of one of said plurality of call event types at said telephone switching center;
- and
- means, responsive to said detecting means, for redirecting said call to said designated telephone number over said telephone switching center.
A method for supporting a call with a mobile subscriber unit in conjunction with an adjunct processor for use in a wireless communications system, said adjunct processor connected to a mobile switching center, said mobile subscriber unit located within a region served by said mobile switching center, said method comprising the steps of:
- instructing said mobile switching center to conditionally redirect said call by said adjunct processor if one of a plurality of call event types subsequently occurs, each call event type associated with a designated telephone number;
- detecting a subsequent occurrence of one of said plurality of call event types by said mobile switching center, responsive to said step of instructing;
- and
- redirecting conditionally said call to said designated telephone number, responsive to said step of detecting, by said mobile switching center.
A method for supporting a voice mail service with a mobile subscriber unit and a party leaving a voice mail entry in conjunction with an adjunct processor for use in a wireless communications system, said adjunct processor connected to a mobile switching center and associated with a designated telephone number, said party associated with an initial redirection telephone number, said mobile subscriber unit located within a region served by said mobile switching center, said method comprising the steps of:
- instructing said mobile switching center to conditionally redirect a call by said adjunct processor if one of a plurality of call event types subsequently occurs, each call event type associated with said designated telephone number;
- redirecting unconditionally said call to said initial redirection telephone number, preceding conditionally redirecting said call and responsive to said step of instructing;
- detecting a subsequent occurrence of one of said plurality of call event types by said mobile switching center, responsive to said step of instructing;
- and
- redirecting conditionally said call to said designated telephone number, responsive to said step of detecting, by said mobile switching center.
