Abstract:
A wireless communication system is disclosed. More particularly, access network selection scheme in visited network in a wireless communication system are disclosed. A method for selecting a Wireless Local Area Network (WLAN) access network by a user equipment (UE) in a visited network may comprise: determining, by the UE, if a selected WLAN access network in the visited network is available; updating, by the UE, a WLAN selection policy with a list of excluded WLAN access network, if the selected WLAN access network in the visited network is not available; and re-determining, by the UE, if there is an available WLAN access network in the visited network based on the updated WLAN selection policy.
Abstract:
A method for enabling a Machine Type Communication (MTC)-InterWorking Function (IWF) to trigger a MTC group in a wireless communication system according to one embodiment of the present invention comprises a step of transmitting a triggering request to a network node. The network node for receiving the triggering request determines success of the triggering request according to group-triggering-related information comprising information on whether the triggering request is transmitted in MTC group units.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for processing a NAS signaling request. A method for performing a non-access stratum (NAS) signaling process by means of a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of receiving a first message that includes information indicating a network failure from a network node of a first network; a step of starting a timer relating to a network selection; and a step of selecting a second network from among network candidates excluding the first network during the operation of the timer relating to a network selection.
Abstract:
The present invention provides a method for processing paging from a server managing mobility in a mobile communication network. The method comprises: receiving from a network node a notification with respect to downlink data to be relayed to user equipment; transmitting a paging signal with respect to the user equipment to one or more base stations; receiving a context request with respect to the user equipment from a different server; recognizing that the paging will fail if the context request with respect to the terminal is received before receiving a reply to the paging; relaying a context reply to the different server depending on the recognition; and transmitting a processing request message with respect to the downlink data to the network node.
Abstract:
An embodiment of the present invention relates to a method for supporting a voice service for a network terminal in a wireless communication system. The method includes transmitting an update location request (ULR) message to a home subscriber server (HSS) by a serving node, wherein if the serving node may not evaluate an IP multimedia subsystem (IMS) voice over PS session-supported indication value for the terminal, the ULR has no information on homogeneous support of IMS voice in a PS session.
Abstract:
The present invention relates to a wireless communication system. More particularly, disclosed are a network-initiated control method and an apparatus for providing a proximity service (ProSe). A method for supporting ProSe between a plurality of terminals at a network node of a wireless communication system according to one embodiment of the present invention comprises: a step of acquiring base ProSe information from one or more of the plurality of terminals or from one or more of other network nodes; a step of allowing the network node to detect whether ProSe is enabled between the plurality of terminals based on the acquired base ProSe information; and a step of transmitting information indicating whether ProSe is allowed or not to one or more of the plurality of terminals.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and device for providing a proximity service. According to one embodiment of the present invention, the method for providing a proximity service (ProSe) for user equipment in a wireless communication system may include: transmitting ProSe capability related information on the user equipment to a network node; receiving information on the provision of a ProSe related network from the network node; determining the ProSe usage of the user equipment based on the ProSe capability related information on the user equipment and/or the received information on the provision of a ProSe related network; and transmitting the determination result of the ProSe usage of the user equipment to the network node.
Abstract:
The present invention relates to a method for enabling a MTC (machine type communication) IWF (interworking function) to perform a trigger request in a wireless communication system. The method includes transferring, to a first serving node, the trigger request and information related to retrying the trigger request which includes information on whether to retry if the transferring of the trigger request fails, wherein if the information on whether to retry indicates retrying, the retrying of the trigger request is assigned to the first serving node.
Abstract:
A method of supporting a user equipment (UE) to UE (UE-to-UE) communication by a network in a wireless communication system, the method includes transmitting a system information block associated with the UE-to-UE communication, wherein the system information block contains a period parameter indicating a periodicity at which a relay UE transmits discovery announcement, wherein the system information block contains a high threshold value and a low threshold value, wherein the relay UE is not allowed to transmit the discovery announcement if a reference signal received power (RSRP) measured by the relay UE is above the high threshold value, and wherein the relay UE is not allowed to transmit the discovery announcement if the RSRP measured by the relay UE is below the low threshold value.
Abstract:
A method and a user equipment (UE) configured for dual priority for controlling a backoff timer are discussed. The method according to an embodiment includes transmitting a first 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; receiving a reject message for the NAS request message from the network node; initiating a session management (SM) backoff timer in response to the reject message; and transmitting a second NAS request message including the low priority indicator set to a second value to the network node while the SM backoff timer is running. The first value of the low priority indicator indicates that the UE is configured for NAS signaling low priority. The second value of the low priority indicator indicates that the UE is not configured for NAS signaling low priority.
