摘要： 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.

摘要： 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.

摘要： A session bundle allocation capability enables dynamic allocation of bundles of sessions being handled by a network element to modules of the network element (e.g., modules such as processing modules configured to perform one or more of traffic processing, traffic switching, and like functions). A bundle of sessions may be allocated by associating a plurality of sessions to form thereby a bundle of sessions, and assigning the bundle of sessions to a processing module group including one or more processing modules configured for processing traffic for the sessions of the bundle of sessions. A bundle of sessions may have a bundle identifier associated therewith and may be migrated from a first processing module group to a second processing module group by changing a mapping of the bundle identifier from being associated with the first processing module group to being associated with the second processing module group.
