  • System and method for session restoration at geo-redundant gateways
    Patent number: 8913484
    Abstract: A method and system for managing a backup service gateway (SGW) associated with a primary SGW, comprising periodically receiving from the primary SGW at least a portion of corresponding UE session state information, the received portion of session state information being sufficient to enable the secondary SGW to indicate to an inquiring management entity that all user sessions associated with a group of mobile devices supported by the primary SGW are in a live state; and in response to a failure of the primary SGW, assuming management of IP addresses and paths associated with the primary SGW and causing each UE supported by the failed primary SGW to reauthorize itself to the network.
    Type: Grant
    Filed: March 18, 2012
    Date of Patent: December 16, 2014
    Assignee: Alcatel Lucent
    Inventors: Vachaspati P. Kompella, Satyam Sinha, Praveen Vasant Muley, Sathyender Nelakonda
  • System and method for session resiliancy at geo-redundant gateways
    Patent number: 8908528
    Abstract: A method, system and apparatus for managing a backup service gateway (SGW) associated with a primary SGW, the backup SGW periodically receiving from the primary SGW at least a portion of corresponding UE session state information and in response to a failure of the primary SGW, assuming management of IP addresses and paths associated with the primary SGW, and in response to receiving control or data plane traffic associated with a UE, generating a Downlink Data Notification (DDN) message adapted to inform an MME that the UE is in a live state.
