Abstract: Disclosed in the present specification is a method by which network nodes calculate an optimum path for virtualized service functions (SFs). The method can comprise the steps of: generating a service function chain (SFC), in which SFs are put in order, on the basis of subscriber information-based user policy information, session policy information, and SF state information; searching for an optimum SF set on the basis of the SFC so as to calculate an optimum service function path (SFP); and updating the SFP when any one of the subscriber information-based user policy information, session policy information, and SF state information is changed.

Abstract: 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.

Abstract: 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.

Abstract: A source BS may determine that handover of a UE to a target BS is needed and transmit a handover request message indicating a request of handover to the target BS to a network node to which the source BS is connected. The handover request message may include radio access network (RAN) type information indicating a target RAN and radio access technology (RAT) type information indicating a target RAT.

Abstract: 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.

Abstract: 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.

Abstract: One disclosure of the present specification provides a routing rule updating method for moving a specific IP flow to a specific access. The updating method can include a step of receiving a routing rule updating request message for network based IP flow mobility (NBIFOM) initiated by a network, wherein the routing rule updating request message can include: a routing rule for moving a specific IP flow of a user device from a first access to a second access; and a timer value calculated by the network. The timer value can be calculated by the network on the basis of at least one of subscriber information, load information and statistical information. The updating method can include the steps of: transmitting an acceptance message to the network in response to the routing rule updating request; and operating a timer according to the timer value.
