Abstract:
The present invention relates to a method and apparatus for a first terminal to perform a proximity service (ProSe) in a wireless communication system. More specifically, the method comprises the steps of: a first terminal transmitting a Prose discovery request to a first network entity; and the first terminal receiving a ProSe discovery response from the first network entity, wherein the ProSe discovery response indicates a refusal of the ProSe if the first terminal and a second terminal area determined not to be in a proximity relationship during a previously configured temporal period.
Abstract:
The present invention relates to a method and an apparatus for managing a user equipment (UE), by a base station (eNodeB), in a wireless communication system supporting a proximity service (ProSe). More particularly, the method comprises the steps of: determining the connection state of a UE; and starting a radio resource control (RRC) inactivity timer when the connection state of the UE is idle, wherein the connection state is determined according to whether the UE performs infrastructure communication and whether the UE performs ProSe communication.
Abstract:
A method for a UE to perform public land mobile network (PLMN) selection associated with ProSe direct communication in a wireless communication system according to an embodiment of the present invention includes: selecting a PLMN; and registering with the PLMN, wherein the UE performs ProSe direct communication in the selected PLMN without executing PLMN selection any more, even if the UE fails to register with the selected PLMN, wherein ProSe direct communication in the selected PLMN is performed in a limited service state, wherein the UE is in the limited service state when the UE has not discovered a suitable cell, when the UE receives "PLMN not allowed" or when the UE receives "GPRS not allowed".
Abstract:
The present invention relates to a mobile communication system and, more particularly, to a method for monitoring the occurrence of an event of a machine type communication (MTC) service in a mobile communication system. In the method for performing MTC monitoring, among MTC features, in particular, when one or a plurality of particular events occur, the occurred events are detected, and when information regarding a corresponding MTC device of the detected event is transmitted to a network entity, the network entity checks stored information regarding the corresponding MTC device; compares the checked information and information regarding the corresponding MTC device of the event, and provides the comparison information or the event-related information to a server that manages and maintains the MTC device.
Abstract:
One embodiment of the present specification provides a method of attempting network access by user equipment (UE). The method comprises the steps of: acquiring, from an upper layer, information related to an application attempting network access when an application specific congestion control for data communication (ACDC) is configured; determining an ACDC category on the basis of the acquired information related to an application; and performing an ACDC test on the basis of the determined ACDC category, wherein a network access trial can be barred or allowed for each application according to the ACDC test.
Abstract:
One embodiment of the present specification provides a method for determining access on the basis of a policy. The method for determining access can comprise the steps for: receiving a plurality of policies including wireless LAN (WLAN) selection rules from a plurality of access network discovery and selection functions (ANDSFs) in a plurality of public land mobile networks (PLMNs); selecting any one of the plurality of policies on the basis of preset location-related criteria; and determining whether traffic of a user is delivered to a 3GPP access or detoured to a WLAN access, according to WLAN selection rules of the selected policy.
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.
