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 serving gateway support node for a radio telecommunications network, in which the serving gateway support node is arranged to control at least one serving gateway to connect user equipment to a packet-based network via a home gateway and is also arranged to cause each serving gateway to hand over the connections between the user equipment and the packet-based network to other serving gateways while maintaining the user equipment's connection to the packet-based network as the user equipment roam throughout the radio telecommunications network, in which the serving gateway support node is arranged to detect a loss of connectivity The serving gateway support node is arranged to re-establish the connection from the user equipment to the packet-based data network via a serving gateway and a home gateway without interrupting the connection of the user equipment to the packet-based network.

摘要： A serving gateway support node (9) for a radio telecommunications network (1), in which the serving gateway support node (9) is arranged to control at least one serving gateway (7) in the radio telecommunications network (1) to connect user equipment (2) to a packet-based network (4) via a home gateway (8) and is also arranged to cause each serving gateway (7) to hand over the connections between the user equipment (2) and the packet-based network (4) to other serving gateways (7) in the radio telecommunications network (1) whilst maintaining the user equipment's (2) connection to the packet-based network (4) as the user equipment (2) roam throughout the radio telecommunications network (1), in which the serving gateway support node (9) is arranged to detect a loss of connectivity between the user equipment (2) and the home gateway (8) or between the serving gateway support node (9) and a serving gateway (7), the serving gateway support node (9) is arranged to re-establish the connection from the user equipment (2) to the packet-based data network (4) via a serving gateway (7) and a home gateway (8) without interrupting the connection of the user equipment (2) to the packet-based network (4). The radio telecommunications network (1) may be a GPRS or LTE (Long Term Evolution) network, and the serving gateway support node (9) may be a mobile management entity (MME).

摘要： A technique for preventing voice announcements in a group call is provided. If any voice activity precedes a B-answer signal on a call to a party, that party is not added to the group call. This approach guarantees that no voice announcements will be added to the group call. With this approach, all subscribers are allowed to use voice mail systems, but subscribers currently forwarding messages to a voice mail system will not be connected to group calls.

摘要： A technique for preventing voice announcements in a group call is provided. A VM tone begins a voice announcement of a voice mail system. Parties that cause the VM tone to be transmitted are not added to the group call. This approach guarantees that no voice announcements will be added to the group call. With this approach, all subscribers are allowed to use voice mail systems, but the subscribers currently forwarding messages to voice mail will not be connected to group calls.
