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: A method and apparatus for determining a multimedia broadcast multicast service (MBMS) interest in a wireless communication system is provided. A user equipment (UE) configures an MBMS threshold, and determines an MBMS interest by comparing a measurement result with the configured MBMS threshold. Only if the measurement result is higher than the configured MBMS threshold the UE determines a frequency, which corresponds to the MBMS interest, to be part of MBMS frequencies of interest.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) determines one random access configuration from a first random access configuration for a normal type of UE and a second random access configuration for a specific type of UE, and transmits a random access preamble based on the second random access configuration to an eNodeB (eNB) if the UE is a specific type of UE. Also, a method and apparatus for establishing, by a UE, a connection in a wireless communication system is provided. The UE transmits a connection request message including bandwidth related information to the eNB.

Abstract: A method and apparatus for configuring a buffer status report (BSR) for a public safety transmission or a vehicle-related (V2X) transmission in a wireless communication system is provided. A user equipment (UE) configures a device-to-device (D2D) logical channel corresponding to the public safety transmission or the V2X transmission, and triggers a proximity-based services (ProSe) BSR for the D2D logical channel. The UE accommodates the triggered ProSe BSR in a media access control (MAC) protocol data unit (PDU) if the MAC PDU can accommodate only one BSR MAC control element (CE).

Abstract: There is provided a method for determining priorities of services. The method may be performed by a user equipment (UE) and comprise: determining, by the UE, whether to prioritize a group communication (GC) service over a non-GC service, wherein the GC service is received through a multimedia broadcast multicast service (MBMS) bearer or through a unicast bearer; and transmitting, from the UE and to a network, an uplink message including an indicator for indicating that the GC service is prioritized over the non-GS service.

Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).
