A user equipment (UE) receives, from a radio access network (RAN), conditional configuration information including (i) a configuration related to a base station or a cell, and (ii) a condition to be satisfied before the UE applies the configuration (2102). The UE determines a procedure to which the conditional information pertains (2104). The UE applies, during the determined procedure, the configuration if the condition is satisfied (2106).

A method and apparatus for cell update while in a Cell_FACH state are disclosed. After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.

The present invention discloses methods and systems for selecting at least one SIM card for data communication at a wireless communication device which is capable of housing a plurality of SIM cards. When a switching condition is satisfied, the wireless communication device selects a second SIM card group, and disconnects one or more connections established using any non-second group SIM card. Non-second group SIM cards are SIM cards that are not in the second SIM card group. A selected SIM card from the second SIM card group is then used for data communications. The steps are repeated until (i) the switching condition is no longer satisfied, (ii) no more SIM cards selected from the second SIM card group can be used for data communications or (iii) no more connection is made using non-second group SIM cards

In a terminal roaming steering method, a steering protocol supported by a terminal and a second AP are determined, and the terminal is steered, based on the steering protocol supported by the terminal, to roam from a first AP to the second AP.

Provided is a method and apparatus for performing a Wireless Fidelity (WiFi) handoff through coordination in a wireless communication system. A first access point (AP) device that transmits a first Bluetooth Low Energy (BLE) advertising packet sets a transmission period identically for the first BLE advertising packet and a second BLE advertising packet, determines transmission timings of the first BLE advertising packet and the second BLE advertising packet, transmits a setting message comprising information about the set transmission period of the second BLE advertising packet and information about the determined transmission timing of the second BLE advertising packet to the second AP device, transmits the first BLE advertising packet to a terminal, and performs a WiFi connection with the terminal, based on a determination by the terminal.
