Method and apparatus for managing communication faults

摘要

A system that incorporates teachings of the present disclosure may utilize, for example, a method involving receiving from a first communication device a service request while providing back-up services to an out-of-service network element, detecting a deficiency in call state information to process the service request, transmitting to the first communication device an error message that prevents termination of an active Internet Protocol (IP) communication path between the first communication device and a second communication device, and receiving from the first communication device a request for an alternate IP communication path for communicating between the first and second communication devices which resolves the deficiency in call state information. Additional embodiments are disclosed.

主权项

1. A first communication device, comprising:
memory including machine readable instructions; and a processor to execute the instructions to perform operations including:
transmitting a first session initiation protocol message that traverses a call signaling path of a communication network to establish a first communication session for communicating with a second communication device, a plurality of network devices in the call signaling path each storing call state information related to the first communication session, the call state information including a first conversation identifier and a first dialog identifier;after a failover network device has replaced one of the plurality of network devices in the call signaling path, transmitting a request message including the first dialog identifier; andin response to receiving an error message from the failover network device indicating that the failover network device has a deficiency associated with the first dialog identifier of the request message, transmitting a second session initiation protocol message over the call signaling path to establish a second communication session with the second communication device while maintaining the first communication session with the second communication device, the second session initiation protocol message including a second dialog identifier to resolve the deficiency of the failover network device.
