摘要:
The present disclosure presents a method of providing information by a subscriber information server for machine type communication (MTC) monitoring. The method may include: receiving information on a monitoring related timer for any MTC device from an MTC related server; adjusting one of the monitoring related timer and a periodic access or location update related timer based on the other timer when there is information on the periodic access or location update related timer for the MTC device; and transmitting information on the adjusted timer to the MTC related server or a monitoring node.

The present invention relates to a method and an apparatus for supporting a proximity service (ProSe) of a first network entity in a wireless communication system. More particularly, the present invention comprises the steps of: a first network entity receiving a request for location information related to a first terminal; transmitting a paging message to the first terminal when the first terminal is in an idle state; receiving a first response message corresponding to the paging message; and transmitting a second response message corresponding to a service request on the basis of the first response message.

A wireless communication system is disclosed. More particularly, access network selection scheme in a wireless communication system are disclosed. A method for selecting an access network by a user equipment (UE) may comprise: determining whether at least one cellular access network is overloaded; determining whether at least one wireless local area network (WLAN) access network is overloaded; determining priorities for the at least one cellular access network and at least one WLAN access network; and selecting one access network among the at least one WLAN access network based on information for access network selection, if the at least one WLAN access network is determined to have a higher priority than the at least one cellular access network, and if each the at least one cellular access network is determined to be overloaded and each of the at least one WLAN access network is determined to be overloaded.

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.

A method for adjusting a timer value for a device includes determining, by a home subscribing server (HSS), a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum time period, wherein the timer value for the RAU or the TAU is determined to be a smaller value than the maximum time period, wherein the maximum time period is related to a loss of a connectivity indicating the device is no longer possible to be signaled, and delivering, by the HSS, information regarding the determined timer value for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

A method is provided for determining an access based on policy. A user equipment (UE) receives a plurality of policies including a wireless local area network (WLAN) selection rule from a plurality of access network discovery and selection functions (ANDSFs) at a plurality of public land mobile networks (PLMNs). The UE receives specific information from at least one PLMN of the plurality of PLMNs. The UE selects a policy among the plurality of policies based on the specific information if there is no user configuration The selected policy is used to select a WLAN access. The plurality of PLMNs include a home PLMN (H-PLMN) and a visited PLMN (V-PLMN).
摘要:
A method of controlling an access, which is controlled by a Mobility Management Entity (MME) of a control plane in a visited network; and the MME therefore are discussed. The method according to one embodiment includes receiving an access request message or an update request message requested by a roaming user equipment (UE) from a Home (e)Node B; and determining Closed Subscriber Group (CSG) information among first CSG information and second CSG information based on predefined priority information when the first CSG information conflicts with the second CSG information. The predefined priority information indicates that the first CSG information takes precedence over the second CSG information. The method further includes transmitting an accept message based on the determined CSG information via the Home (e)Node B. The first CSG information is CSG-related information defined in a home network and the second CSG information is CSG-related information in the visited network.

The present invention relates to a wireless communication system, and more particularly, to a paging method and apparatus for an IMS service. A method which supports paging to provide an internet protocol multimedia subsystem (IMS) service to a terminal in a network node in accordance with an embodiment of the present invention may include the steps of: receiving downlink data forwarded to the terminal; when there is a determination to apply differentiated paging to the downlink data, adding information indicating that the differentiated paging is applied, to a message including the downlink data; and transmitting the message including information indicating that the differentiated paging is applied, to another network node.

One embodiment of the present specification provides a method for selecting or reselecting a relay for a proximity service. The method comprises the steps of: receiving, by user equipment (UE) which is to receive a relay service, synchronization signals from a plurality of other UEs capable of operating as relays; and receiving, by the UE, announce messages from the plurality of other UEs capable of operating as the relays. Here, the announce messages from each of the other UEs can contain relay type information on whether to support a UE-to-network relay service, packet data network (PDN)/access point name (APN) information, and service/group information. The method further comprises the steps of: generating, by the UE, a candidate relay list on the basis of the relay type information, the PDN/APN information, and the service/group information within the announce messages received from the plurality of other UEs; and selecting or reselecting, by the UE, one of the other UEs within the candidate relay list in consideration of relay type, PDN/APN, and service/group information necessary for a service of the UE.

The present description discloses a public land mobile network (PLMN) selection method. The PLMN selection method comprises the steps of: running a first timer if a first request message has been transmitted multiple times to a first network node in a first PLMN, but a response message has not been received; selecting a second PLMN after the first timer has been started; and maintaining, without stopping, the first timer, which has been run for the first PLMN, even if a second request message has been sent to a second network node in the second PLMN, and an acceptance message for same has been received, wherein the retransmission, by reselecting the first PLMN, of the first request to the first network node in the first PLMN can be prevented until the first timer has expired.
