1. A method, comprising:
- detecting, by a system comprising a processor, a failure in a first core delivery system associated with a voice over cellular carrier service; and
re-routing, by the system, services associated with the first core delivery system to a second core delivery system in response to detecting the failure in the first core delivery system, wherein the re-routing of the services is facilitated based on synchronizing a first subscriber data store associated with the first core delivery system and a second subscriber data store associated with the second 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.

8. A non-transitory computer-readable storage medium storing computer-executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:
-
identifying a failure in a first redundant core delivery system associated with voice over a cellular carrier; and processing data traffic associated with the first redundant core delivery system and a second redundant core delivery system by the second redundant core delivery system in response to services associated with the first redundant core delivery system being re-routed to the second redundant core delivery system after identifying the failure in the first redundant core delivery system. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system, comprising:
-
a memory to store instructions; and a processor, coupled to the memory, that facilitates execution of the instructions to perform operations comprising; processing and delivering a portion of first data traffic related to a voice over cellular carrier service that is associated with a first redundant core delivery system; and processing and delivering second data traffic related to the voice over cellular carrier service that is associated with a second redundant core delivery system, wherein the second redundant core delivery system interconnects to the first core delivery system, wherein stored data is synchronized between the first redundant core delivery system and the second redundant core delivery system, and wherein the second redundant core delivery system processes another portion of the first data traffic associated with the first redundant core delivery system and the second data traffic associated with the second redundant core delivery system in response to a re-routing of services associated with the first redundant core delivery system to the second redundant core delivery system performed in response to identification of a failure in the first redundant core delivery system. - View Dependent Claims (15, 16, 17, 18, 19, 20)
