Abstract: A method is presented for controlling timers in a wireless communication system. When an idle mode signaling reduction (ISR) function of a user equipment (UE) is activated in the UE, a periodic tracking area update (P-TAU) timer and a periodic routing area update (P-RAU) timer are started. The P-TAU timer and the P-RAU timer run in the UE for updating a Mobility Management Entity (MME) and a Serving General packet radio service Support Node (SGSN) independently. The ISR function is activated when an update message activating the ISR function is received by the UE. When the P-TAU timer expires and the UE cannot initiate a tracking area update (TAU) procedure as a mobility management backoff (MM-BO) timer is running, a deactivate ISR timer corresponding to a first type network is started. The MM-BO timer is a timer configured to start when a MM-BO time value is received in the UE.

Abstract: For Inter-APN routing flow distribution, a step of receiving, by a UE from a server, an Inter-System Routing Policy (ISRP) rule that comprises flow distribution rules for at least one of a For Flow Based flow distribution container used for IP Flow Mobility (IFOM), a For Service Based flow distribution container used for Multi-Access PDN Connectivity (MAPCON), a For Non-Seamless Offload flow distribution container used for Non-Seamless WLAN Offload (NSWO), and an Inter-APN routing flow distribution container, is performed. Here, the Inter-APN routing flow distribution container comprises information related to routing IP flows with respect to a plurality of APNs for using PDN connections to access multiple IP networks. Then a step of selecting, by the UE, among active/valid flow distribution rules in the received ISRP rule, a flow distribution rule having highest priority is performed.

Abstract: A method of processing data associated with mobility of a user equipment (UE) in a wireless network is described. A mobility management entity (MME) starts an activation procedure for a default bearer for a packet data network (PDN) connection associated with a local Internet protocol access (LIPA). If a base station rejects an establishment of the default bearer for the PDN connection associated with the LIPA due to a triggered handover, the MME transmits a PDN connection reject message including a cause value, and releasing a network resource allocated for the activation procedure.

Abstract: A method and a user equipment (UE) are described for controlling timers in a wireless communication system including a first type network communicating based on a number of orthogonal frequency-division multiplexing (OFDM) symbols and a second type network which is different from the first type network. An update message is received that activates an idle mode signaling reduction (ISR) function of the UE. If the ISR function is activated in the UE, a periodic tracking area updating (P-TAU) timer is started, which is used to periodically notify availability of the UE. If the P-TAU timer expires and a mobility management backoff (MM-BO) timer is running, a deactivate ISR timer corresponding to the first type of network is started. The MM-BO timer is configured to start when a MM-BO time value is received at the UE.
