Abstract: There is provided a method for a network fault recovery. The method may be performed by a policy and charging rule function (PCRF) node and comprise: transmitting, to a traffic detection function (TDF), a first request for monitoring a session initiation protocol (SIP) based signal to be routed over a first internet protocol (IP) version based network, if a fault of the first IP version-based network is detected; receiving, from the TDF, a report indicating that the SIP based signal is detected; transmitting a first indication for initiating a IP connectivity access network (IP-CAN) session termination procedure to a packet data network gateway (P-GW). Here, the first indication may include a cause value indicating a reactivation is requested such that the P-GW enables a user equipment (UE) to perform a detach procedure and then a reattach procedure.

Abstract: A method and a network entity for controlling a service in charge of a control plane in a network are discussed. The method according to an embodiment includes receiving subscription information including an indicator related to a selected internet protocol (IP) traffic offload (SIPTO). The method further includes triggering a re-establishment of the SIPTO when a movement of a user equipment from an (e)Node B to a Home (e)Node B is detected; allowing the SIPTO excluding a SIPTO at the local network based on an access point name (APN) when the indicator indicates that the SIPTO is allowed and the SIPTO at the local network is excluded; and allowing the SIPTO including the SIPTO at the local network based on the APN when the indicator indicates that the SIPTO is allowed and the SIPTO at the local network is included.

Abstract: Disclosed are a serving node relocating method in a wireless communication system and a device for same. In detail, a method for relocating, by a first serving node, a serving node in a wireless communication system can include: receiving a tracking area update (TAU) request message from a terminal; transmitting an update location request to a home subscriber server (HSS), when the first serving node having received the TAU request message is different from a second serving node that is an old node; and transmitting an update location message to a service capability exposure function (SCEF), when the first serving node is different from the second serving node that is the old node and a connection for transmitting/receiving non-internet protocol (non-IP) data via the SCEF is configured in the terminal.

Abstract: A method of controlling a backoff timer at a user equipment (UE) configured for dual priority, the method includes transmitting a non access stratum (NAS) request message without an access point name (APN) including a low priority indicator set to a first value to a network node, wherein the first NAS request message without the APN is an attach request message transmitted along with a packet data network (PDN) connectivity request without the APN; receiving a reject message for the NAS request message from the network node, and wherein a cause in the reject message is set to insufficient resources; setting the low priority indicator to a second value; and initiating a new attach procedure without the APN, while a session management (SM) backoff timer is running, wherein the first value of the low priority indicates that the UE is configured for NAS signaling low priority.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and a device for cancelling a device trigger. The method for cancelling a device trigger in a wireless communication system, according to one embodiment of the present invention, can comprise the steps of: receiving a cancellation request for a first trigger message in a network node; and transmitting a second trigger message to the terminal if the first trigger message has been transmitted to the terminal and the cancellation request indicates a replacement request. The second trigger message can include information which indicates that the cancellation of the first trigger message has been requested.

Abstract: An example of the present disclosure provides a method of selecting access. The method of selecting access may include the steps of: selecting a first access point name (APN) that does not support IP flow mobility and seamless offload (IFOM) according to a first setting related to APN-based routing; checking a preferred flag when wireless local area network (WLAN) access for the IFOM is selected according to a second setting related to routing resulting in a collision between the first setting and the second setting; and using any one of the first setting and the second setting according to the preferred flag.
