Abstract:
Systems and methods of directing a mobile user to a redirect server when the mobile user experiences session startup failure thereby reducing repeated attempts to establish a session during session startup failure. A first request is received in packet gateway to create a mobile session in a mobile network for a mobile device. A second request is transmitted to a server, the second request associated with an inquiry regarding a status of the mobile device. A call failure indication is received from the server for the mobile device. An indication of call success is transmitted to a serving gateway, and a redirect session is created such that the mobile device is directed to a redirect sever during the redirect session, thereby reducing repeated attempts to establish a session during session startup failure.
