摘要:
The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for performing or supporting machine-type communications (MTC). A method for a terminal to establish a connection to a server according to one embodiment of the present invention comprises the steps of: receiving a triggering message including a triggering identifier from a network; and a step of requesting a data connection to the server using the triggering information contained in the triggering message. The triggering identifier can be set to a predetermined value for distinguishing the triggering message from other types of messages.

In a first embodiment, a specific UE is enabled to copy all or a portion of one or more or media in an ongoing session with a remote end to another UE, so that the media can be shared by many UEs. In a second embodiment, when a specific UE shares all or a portion of media in an ongoing session with another UE, the shared media may be controlled.

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)NodeB. 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)NodeB, a local IP access (LIPA) service can be selectively supported according to the user or a UE.
摘要:
The present invention relates to a method for controlling an overload of a network, which may be generated due to a service request of a terminal in a mobile communication system of machine type communication (MTC). The invention controls a network overload and efficiently use network resources, by requesting activation of a particular MTC function to the network on the basis of information on changes in unnecessary MTC functions, without allowing a terminal to request (for example, attach request) the unnecessary MTC functions.

The present invention relates to a wireless communication system, and more particularly, a method and apparatus for accessing via a local network are disclosed, A method for transmitting local network selected Internet protocol traffic offload (SIPTO) indication information, according to one embodiment of the present invention, comprises the steps of: generating from a first network node local network SIPTO packet data network (PDN) connection indication information with respect to a PDN connection of a user equipment (UE); and transmitting the local network SIPTO PDN connection indication information to the UE, wherein the local network SIPTO PDN connection indication information can express whether the PDN connection of the UE is a local network SIPTO PDN connection.

The present invention provides a method for supporting mobility of selected IP traffic offload (SIPTO) by a server undertaking a control plane in a mobile communication network. The method can comprise the following steps: receiving a handover request message for a terminal receiving a SIPTO service by means of a source base station to a target base station; deciding whether to deactivate the SIPTO service; performing a process for disconnecting a public data network connection (PDN) for the SIPTO, based on the decision; and transmitting to the terminal via the source base station a message including information for reactivating the SIPTO after the handover, according to the decision.

The present invention relates to a method for controlling traffic congestion of MTC devices in a mobile communication system which provides a machine type communication (MTC) service. The method of the present invention is configured in that a core network node (for example, MME, MSC, SGSN, etc.) performs scheduling and rescheduling procedures on data communication traffic for user equipment (that is, MTC deices) using subscription information and congestion control information of the user equipment; and generates a resultant “recalculated time interval” parameter and transmits the parameter to the user equipment, thereby efficiently distributing the amount of data communication (that is, traffic) concentrated to a specific time slot, and thus controlling traffic congestion or network overload.

A method for interworking messages of heterogeneous, and which includes acquiring a temporary identifier of the sending terminal when the sending terminal is a terminal that subscribes in an IP multimedia subsystem (IMS) without a mobile communication global unique number, in which the temporary identifier is an identifier used for transmitting a short message during an IMS registration valid period of the sending terminal; receiving a session initiation protocol (SIP) based message transmitted by the sending terminal from an IMS based session controller; acquiring a temporary identifier of a receiving terminal based on an SIP based identifier of the receiving terminal encapsulated in the SIP based message; and generating a short message service (SMS) based message based on the received SIP based message, the temporary identifier of the receiving terminal, and the temporary identifier of the transmitting terminal.

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.

In order to perform SIPTO@LN for PDN connections, MME performs: receiving, from a HeNB, information about one or more GWs, said information comprising an IP address of each local GW and at least one among APN-specific information for said one or more local GWs and/or a non-APN-specific indication for said one or more local GWs; initiating, based on subscription data and the received information about a particular local GW among said one or more local GWs, deactivation of one or more PDN connections by sending to UE a NAS Deactivate Bearer Request message indicating that reactivation is required for said one or more PDN connections; and selecting, in response to a reactivation attempt by the UE and based on said subscription data and the received information about said particular local GW, said particular local GW to allow SIPTO@LN to be performed via said particular local GW.
