Redundancy mechanisms in a push-to-talk realtime cellular network
First Claim

1. A system that facilitates data communication, comprising:
- a first redundant core delivery system that processes and delivers data related to realtime voice over a cellular carrier; and
a second redundant core delivery system that interconnects to the first core delivery system such that stored data can be synchronized therebetween;
wherein the first and second core delivery systems are configured in an active-active configuration;
wherein if the first redundant core delivery system fails, services associated with the first redundant core delivery system are managed by the second redundant core delivery system such that if the first redundant core delivery system is restored after failure, the services associated with the first redundant core delivery system are automatically rerouted to the first redundant core delivery system from the second redundant core delivery system.

Abstract
Redundant mechanism in a push-to-talk (PTT) realtime architecture. Redundancy is provided in core delivery systems, which are employed for the emulation of “walkie-talkie” service with circuit switched duplex calls in the carrier network. The disclosed architecture provides for geographic and/or realtime mated redundancy. In one implementation, realtime redundancy is offered in an active-active scenario, although other scenarios are possible. Similarly, redundancy is provided in a roaming gateway implementation of the PTT network.

13. A system that facilitates data communication, comprising:
-
a first roaming gateway system for processing and delivery of data related to realtime voice over a cellular carrier; and a second roaming gateway system interconnected to the first roaming gateway system in an active-active configuration such that the second roaming gateway system automatically handles the services of the first roaming gateway system when the first roaming gateway system fails; wherein the first and second roaming gateway systems connect redundantly to a mated pair of gateway STP devices to control traffic distribution between the first and second roaming gateway systems. - View Dependent Claims (14)

15. A method that facilitates data communication, comprising:
-
generating a first redundant core delivery system that processes and delivers data relating to realtime voice over a cellular carrier, wherein the data is stored in a first subscriber database of the first core redundant delivery system; generating a second redundant core delivery system that interconnects to the first redundant core delivery system, the second redundant core delivery system comprises a second subscriber database of stored data; interfacing both the first and second core delivery systems to each other; configuring the first and second redundant core delivery systems in an active-active configuration; synchronizing the first and second subscriber databases when both the first and second core delivery systems are operational; identifying a failure in either the first core delivery system or second core delivery system, wherein if a failure of the first core delivery system is identified, re-routing services associated with the first core delivery system to the second core delivery system; restoring the first core delivery system after failure thereof; re-routing services from the second core delivery system back to the first core delivery system; and re-synchronizing the first and second subscriber databases. - View Dependent Claims (16, 17, 18, 19, 20)
