摘要： Embodiments of the invention include a method for providing UE session resilience performed in a first PDN-GW that is coupled to a second PDN-GW, which are both in a PDN-GW pool. The method provides UE session resilience by allowing the first PDN-GW to provide connectivity for UE sessions previously serviced by the second PDN-GW after the second PDN-GW becomes non-operational. The first PDN-GW recognizes that the second PDN-GW failed and then activates a plurality of standby UE sessions. Each standby UE session is a backup UE session corresponding to a previously active UE session serviced on the second PDN-GW. Each standby UE session is associated with a UE device and a network resource identifier of an APN slice. The first PDN-GW transmits a message to a SGW that is servicing the UE sessions that indicates that the SGW should direct traffic previously bound for the second PDN-GW to the first PDN-GW.

摘要： A method in a server for controlling the distribution of messages from a plurality of clients among a plurality of processing means, including the steps of: establishing whether a message received on an interface board of the server is addressed using a normal identity specific for the client that sent the message and, if yes, then: using a first algorithm to map the normal identity to a load index in a first mapping means; and, mapping the load index to one of the plurality of processing means using a mapping table provided in the interface board. If the message is addressed using an internal identity generated in the server, rather than the normal identity specific for the client that sent the message, then: using a second algorithm to map the internal identity to a load index in a second mapping means; and, mapping the load index to one of the plurality of processing means using the mapping table provided in the interface board.

摘要： A pool of functional server nodes in a packet data network, and method of transferring a given mobile terminal from a current functional server node to a target functional server node in the pool. An interface enables each functional server node to control any, or a number of, radio network control nodes. When a transfer is desired, the pool selects the target functional server node and initiates a transfer of control responsibility for the given mobile terminal's connections from the current functional server node to the selected target functional server node. The control responsibility is then transferred to the selected target functional server node without interrupting service to the given mobile terminal.

摘要： Communication sessions are each homed on one of a plurality of line cards in a network element. Packets received by the network element are processed on the home card before being transmitted to a subscriber device, such as a mobile phone or laptop computer. When a packet is received by the network element, it is not necessarily received by the line card that serves as a home card for the respective session. The packet is switched within the network element from the receiving line card, i.e., the trunk card, to the home card. The network element identifies the home card by performing a lookup in a table duplicated on all the line cards using the least significant bits of the IP address in the packet. Using these bits to organize the table limits the size of the table and balances load among the line cards.
