Abstract:
The invention relates to a method for traversing a NAT device residing in a backhaul IP network. A home cellular base station (HeNB) and a collocated local gateway (L-GW) providing access to a local IP network are connected to a mobile operator's packet core network through the NAT device. The method comprises the steps of opening an IPsec tunnel between the home cellular base station (HeNB) and a security gateway (SeGW) via the NAT device, and of tunneling two interfaces through the same IPsec tunnel, wherein a first interface is an interface whose local endpoint is the home cellular base station (HeNB) and whose remote endpoint is a node residing in the operator's packet core network, and a second interface is an interface whose local endpoint is the local gateway (L-GW) and whose remote endpoint is a node residing in the operator's packet core network. The invention also relates to a node comprising a home cellular base station (HeNB) and a collocated local gateway (L-GW).
Abstract:
Method for allowing a mobile terminated communication to a destination device (2) through at least one mobile communication network (10) from a source entity (1) located in a public IP address network (9). The method comprises: a subscriber server (3) of the mobile communication network receiving an IP address ("D") of the destination device from a node (4) of the mobile communication network, and the subscriber server updating a DNS record containing a static unique identifier of the destination device stored in an authoritative DNS server (5) reachable via the public IP address network, with said destination device IP address.

Abstract:
Disclosed is a method of controlling a session in a serving server taking charge of the control plane within a mobile communication network. The control method may include receiving, by the serving server, a tracking area update (TAU) request message of a terminal from a target base station; retrieving, by the serving server, a previous server that has taken charge of the control plane for the terminal; receiving, by the serving server and from the retrieved previous server, a context response message comprising information indicating that a session for the terminal had been established to be passed through a path over the nodes within a fixed network different from a mobile communication network; deciding, by the serving server, whether gateway relocation is needed; releasing, by the serving server, the established session; transmitting, by the serving server, an accept message comprising information for the processing result to the terminal through the target base station; and establishing, by the serving server a session passing through a path over the nodes within a fixed network different from a mobile communication network based on the information.
Abstract:
MSC server enhanced for rSRVCC from UTRAN/GERAN to E-UTRAN/HSPA, comprising: - a reception block (10) configured to receive an rSRVCC capability indication from a user equipment; - a decision block (11) configured to determine whether rSRVCC is allowed for a given call based on the rSRVCC capability indication received; and - a transmitting block (12) configured to send to a Radio Access Network (RNS/BSS), when rSRVCC has been determined as allowed, an rSRVCC possible indication indicating that a rSRVCC is possible.
Abstract:
According to the present description, data of a user can be detoured (offloaded) to a wired network such as a public communication network even through a home (e) Node B. In addition, when the data of the user is detoured (offloaded) to the wired network such as the public communication network even through the home (e) Node B, a local IP access (LIPA) service can be selectively supported according to the user or a UE.
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 setting, and the control signal having the encapsulated MTC data is sent between a network and a terminal, thereby optimising network resource efficiency and reducing the wireless channel load.
Abstract:
A Mobility Management Entity (MME) comprises at least one entity or layer having Mobile Switching Center (MSC) functionality to support a Short Messaging Service (SMS) between a network and a mobile station by employing Machine-to-Machine (M2M) or Machine Type Communication (MTC) protocols. A first state machine entity or layer that supports relay functions to perform forwarding of SMS messages to the mobile station. A second state machine entity or layer that supports connection functions with at least an HSS/HLR (Home Subscriber Server / Home Location Register), and with an SMS-SC (Short Messaging Service -Service Center) or GMSC/IWMSC (Gateway MSC / Interworking MSC).
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 E- 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.
