Repeat dialing in wireless networks to busy called parties
View Patent ↗A wireless network is disclosed that provides repeat dialing to busy called parties. The wireless network includes an originating MSC system that serves a calling party, and a terminating MSC system that serves a called party. The calling party initiates a call to the called party through the originating MSC system, and the terminating MSC system determines that the called party is busy on another call. The originating MSC system then receives a repeat dialing instruction from the calling party and transmits a repeat dialing indicator to the terminating MSC system. The terminating MSC system identifies when the called party becomes available in substantially real time. When available, the terminating MSC system attempts to set up a call between the called party and the calling party.
1. A system comprising:
a terminating Mobile Switching Center (MSC) system operable to serve a mobile called party;
the terminating MSC system further operable to receive a call setup message to set up a call to the mobile called party, and to determine that the mobile called party is busy;
the terminating MSC system further operable to monitor the availability of the mobile called party to identify when the mobile called party becomes available, and to page the mobile called party responsive to identifying that the mobile called party has become available to immediately attempt to set up the call to the mobile called party at the terminating side when the mobile called party becomes available to implement repeat dialing.
2. The system of claim 1 wherein:
the terminating MSC system is further operable to monitor the availability of the mobile called party to identify when the mobile called party becomes available in real-time.
3. The system of claim 1 wherein:
the terminating MSC system is further operable to monitor the availability of the mobile called party responsive to receiving a repeat dialing indicator from an originating side of the call to activate repeat dialing for the call.
4. The system of claim 3 wherein:
the terminating MSC system is further operable to receive a RoutingRequest invoke message that includes the repeat dialing indicator.
5. The system of claim 1 wherein the mobile called party is on another call.
6. The system of claim 1 wherein the mobile called party does not subscribe to call waiting.
7. A method comprising:
receiving a call setup message in a terminating Mobile Switching Center (MSC) system to set up a call to a mobile called party that is served by the terminating MSC system;
determining, in the terminating MSC system, that the mobile called party is busy;
monitoring, in the terminating MSC system, the availability of the mobile called party to identify when the mobile called party becomes available; and
paging the mobile called party with the terminating MSC system responsive to identifying that the mobile called party has become available to immediately attempt to set up the call to the mobile called party at the terminating side when the mobile called party becomes available to implement repeat dialing.
8. The method of claim 7 wherein monitoring the availability of the mobile called party comprises:
monitoring the availability of the mobile called party to identify when the mobile called party becomes available in real-time.
9. The method of claim 7 wherein monitoring the availability of the mobile called party comprises:
monitoring the availability of the mobile called party responsive to receiving a repeat dialing indicator from an originating side of the call to activate repeat dialing for the call.
10. The method of claim 9 further comprising:
receiving, in the terminating MSC system, a RoutingRequest invoke message that includes the repeat dialing indicator.
11. The method of claim 7 wherein the mobile called party is on another call.
12. The method of claim 7 wherein the mobile called party does not subscribe to call waiting.
13. A system comprising:
a switching system at a terminating side of a call from a calling party to a mobile called party, the switching system operable to receive a call setup message for the call, to determine that the mobile called party is busy, to monitor the availability of the mobile called party to identify when the mobile called party becomes available, to transmit a page to the mobile called party responsive to determining that the called party becomes available, and to attempt to set up the call to the mobile called party responsive to receiving an answer to the page from the mobile called party.
14. The system of claim 13 wherein:
the switching system is further operable to monitor the availability of the mobile called party to identify when the mobile called party becomes available in real-time.
15. The system of claim 13 wherein:
the switching system is further operable to monitor the availability of the mobile called party responsive to receiving a repeat dialing indicator from the calling party to activate repeat dialing for the call.
16. The system of claim 15 wherein:
the switching system is further operable to receive a RoutingRequest invoke message that includes the repeat dialing indicator.
17. The system of claim 13 wherein the mobile called party is on another call.
18. The system of claim 13 wherein the mobile called party does not subscribe to call waiting.
