摘要： A method for a user equipment (UE) connecting to a network includes: if second connection is to be executed by means of a second access, determining whether or not first connection has been previously executed by means of a first access; and, if the first connection by means of the first access has been executed and the second connection by means of the second access is determined to be an addition, transmitting a connection request message comprising identification information of a control plane (CP) function node. The identification information of the control plane (CP) function node could have been obtained during the first connection by means of the first access. Both the first connection by means of the first access and the second connection by means of the second access can be managed by means of the control plane (CP) function node.

摘要： Data-off can be activated in a user equipment. If a packet data network gateway receives a downlink packet to be transmitted to the user equipment in which data-off has been activated, the packet data network gateway transmits to the user equipment, or blocks, the downlink packet for the user equipment by using a filter associated with a data-off exception service.

摘要： Disclosed are a method and apparatus for transmitting downlink data in a wireless communication system. More specifically, a method for transmitting downlink data to a user equipment (UE) in a wireless communication system comprises receiving, by a Mobile Management Entity (MME), a Downlink Data Notification message from a Serving Gateway (S-GW); and in case the MME detects that a UE is in a sleep mode, transmitting, by the MME, a response message for indicating buffering of downlink data to the S-GW, wherein the response message includes buffering time of the downlink data, and the buffering time is a time period until the UE is expected to switch from the sleep mode to a reachable state.

摘要： A method is provided for performing network selection and traffic routing. A user equipment (UE) receives an Access Network Discovery and Selection Function (ANDSF) rule including an Inter-System Routing Policy (ISRP) rule or an Inter-Access Point Name (Inter-APN) Routing Policy (IARP) rule. The UE receives, from a base station, radio access network (RAN) assistance information. The RAN assistance information received from the base station is used to evaluate the ISRP rule or the IARP rule of the ANDSF rule. The UE evaluates whether the ISRP rule or the IARP rule of the ANDSF rule is valid or not by using the RAN assistance information. The UE selects one of the RAN assistance information and the ANDSF rule including the ISRP rule or the IARP rule.

摘要： One disclosure of the present specification provides a method for performing a multimedia telephony (MMTEL) service in a machine type communication (MTC) device. The method can comprise the steps of: receiving, from an upper layer, an indication in which a mobile orienting (MO) MMTEL service is initiated; setting a special call type for the MMTEL service in a call type field within a request message for performing the MMTEL service; and transmitting the request message to a lower layer, wherein, when the request message is transmitted to the lower layer, if the MMTEL service is initiated, the MTC device does not transmit an extended access barring (EAB) application indication to the lower layer or can transmit, to the lower layer, an indication commanding the EAB to be skipped, even if the EAB is set.
