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 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.
