    Abstract: A node is provided that includes a home base station collocated with a local gateway (L-GW) providing access to a local Internet Protocol (IP) network. The node performs an establishment procedure with a security gateway (SeGW), and discriminates a packet. The node uses a first interface configured at the L-GW and a second interface which is configured between the home base station and a gateway for the home base station. The first and second interfaces are tunneled through a same IP security (IPsec) tunnel opened between the home base station and the SeGW. The home base station for the first interface uses a first IP address that is either same as or different from a second IP address used by the home base station for the second interface. The node uses either distinct ranges of Tunnel Endpoint Identifiers (TEIDs) or the first and second IP addresses to discriminate the packet.

    Abstract: Method for performing an rSRVCC procedure from UTRAN/GERAN to E-UTRAN/HSPA, comprising steps of: —receiving, a first network entity, a first message from a UE before an rSRVCC handover procedure from URTAN/GERAN to F-E-UTRAN/HSPA involving the UE, the first message containing a pre-allocated transport address to be used for voice after the rSRVCC handover, —sending a second message, during the rSRVCC handover procedure of a voice call, to a second network entity, the second message comprising information related to the transport address of the UE to give an instruction to send the voice media of the call to that transport address.

    Abstract: Disclosed are devices and methods for provisioning of voice and other CS-domain services. A first server (22) comprises a call reception block (221) configured to receive an incoming voice call, from a first user equipment; a transmitting block (222) configured to send, in response to the reception of the incoming voice call, a paging request to a second server; a service request reception block (223) configured to receive, from the second server, an SGs service request message, and; a trigger block (224) configured to use the SGs service request message as a trigger to send an indication of user alerting to the first user equipment when the SGs service request message indicates that a second user equipment was in Connected mode.
