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: The present invention relates to a mobile communication system, and more particularly relates to a method for transmitting a small-sized control signal (also known as “small data”) using a control plane in a MTC (machine-type communication) service in a mobile communication system. In the present invention, MTC data is encapsulated in an existing control procedure or control message or the like, on a control signal, without performing packet data bearer setup, and the control signal having the encapsulated MTC data is sent between a network and a terminal, thereby optimizing network resource efficiency and reducing the wireless channel load.

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 translation: 用于从UTRAN / GERAN到E-UTRAN / HSPA执行rSRVCC过程的方法，包括以下步骤：在从URTAN / GERAN到FE-UTRAN / HSPA的rSRVCC切换过程之前，从第一网络实体接收来自UE的第一消息 涉及所述UE，所述第一消息包含在rSRVCC切换之后用于语音的预分配传输地址，在语音呼叫的rSRVCC切换过程期间发送第二消息到所述第二网络实体，所述第二消息包括 与UE的传输地址相关的信息，以给出将呼叫的语音媒体发送到该传输地址的指令。

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.

Abstract: The invention relates to a home cellular base station (HeNB), comprising a radio interface (RI), to communicate with a user equipment (UE), a local interface (LI), to communicate with a local gateway (L-GW) providing access to a local IP network, a user plane interface (S1-U), to communicate with a serving gateway (SGW), and a control plane interface (S1-MME), to communicate with a control node (MME). The home cellular base station (HeNB) further comprises a selection module (SelMod) set to obtain a first correlation ID for enabling a direct user plane path between the home cellular base station (HeNB) and the local gateway (L-GW), the first correlation ID being obtained via the control plane interface (S1-MME) upon each establishment of a bearer providing access to the local IP network.The invention also relates to a control node (MME), to a home subscriber server (HSS), to a direct path enablement method, and to a PDN management method.

Abstract: A method and a user equipment (UE) for routing a data packet in a wireless communication network are discussed. The method according to an embodiment includes establishing, by the UE, a packet data network (PDN) connection via a 3rd Generation Partnership Project (3GPP) cellular network; obtaining, by the UE from an Access Network Discovery and Selection Function (ANDSF) server, a routing rule including information on an access point name (APN) and a priority of the APN, the APN identifying a packet data network (PDN) connection; and performing, by the UE, an offload function by selecting a gateway via the 3GPP cellar network based on the priority of the APN. The routing rule comprises identification information in the form of an IP 5-tuple allowing the UE to route the data packet.
