Abstract:
1. A method, comprising: receiving communications from a user device on a first network to initiate a session with a second network; receiving, from a network device on the second network, state information for the user device associated with the session, wherein the state information comprises service route information and identification information for the user device, and wherein the state information is received in the first network on a gateway that includes a user plane application, which is configured to maintain the state information for the session including having the service route information associated with the user device identification information; communicating with the network device through a network interface, wherein the network device includes a network application to be used in conjunction with the session; receiving, on the gateway, a service route request from the network device to recover the service route information associated with the user device identification information, wherein the request is triggered when the network application attempts to re-initialize after a failure associated with the network application; and communicating the service route information associated with the user device identification information from the gateway to the network application, wherein the network application is configured to continue the session for the user device by using the service route information and without needing to establish a new session for the user device.
