摘要:
A notification method for informing a UE of an existence or absence of control information for an MBMS in a mobile communication system supporting the MBMS. In the method, the UE receives a notification indicator channel independently reporting the existence of the control information for the MBMS, confirms at least one notification indicator of the notification indicator channel, thereby confirming the existence of the control information relating to the requested MBMS. Further, a method is proposed, which can minimize an alarm due to other MBMSs.

摘要:
A method and apparatus for performing measurement by a User Equipment (UE) in a mobile communication system are provided. The UE has a Discontinuous Reception (DRX) mode for discontinuously receiving data and a continuous reception mode for continuously receiving data. The mobile communication system also has a serving cell where the UE is located, and a neighboring cell located near the serving cell. Signal strength of the serving cell is measured according to a period of the DRX mode. The signal strength measurement is continuously performed on the serving cell and the neighboring cell, if the measured signal strength of the serving cell is less than or equal to a particular threshold. The continuous signal strength measurement is stopped and signal strength of the serving cell is measured according to the period of the DRX mode, if the continuously measured signal strength of the serving cell is greater than the particular threshold.

A method and apparatus for increasing the success rate of a handover of a connected mode UE while minimizing the power consumption of the UE during DRX operation in a mobile communication system is provided. The method includes the steps of transmitting a cell change report to the serving base station, and then suspending the DRX operation to transition to an active mode; receiving a handover command message, and completing the handover to a target cell; checking if the handover command message includes a DRX resume command; waiting until a control message including the DRX resume command is received from the target base station; and after the control message including the DRX resume command is received, transitioning from the active mode to a sleep mode, and resuming the DRX operation.

A method and apparatus for controlling measuring the frequency of a new cell within a forbidden registration area when a User Equipment (UE) enters into the new cell in a mobile communication system are provided. If the UE recognizes the new registration area as forbidden, the UE does not measure the frequency of the current cell for a predetermined reference time, and searches for a suitable cell for a normal service by measuring other frequencies. If no suitable cell in the other frequencies is found, the UE removes a measuring limitation and searches for an acceptable cell for a limited service by measuring frequencies including frequency of the current cell.

A user equipment (UE) is provided which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.

A method and apparatus for DRX of a UE in a mobile communication system are provided, in which the UE receives setting information from a network, the setting information including a first DRX cycle length and a second DRX cycle length for a predetermined data service. Upon generation of uplink data, the UE transitions to a downloading phase in which active periods are set according to the first DRX cycle length.

A method and apparatus for detecting contention in an RA procedure in a mobile communication system is provided in which an L2/L3 message is received from a UE in uplink resources allocated to the UE by an RA preamble response message that was transmitted for an RA procedure initiated by the UE, a CR message associated the RA procedure is transmitted to the UE, if the L2/L3 message is an initial access message, and predetermined control information is transmitted to the UE on a downlink control channel without transmitting the CR message, if the L2/L3 message is not an initial access message.

A method and apparatus are provided for receiving system information during inter-cell movement of a user equipment (UE) in a network sharing (NS) system. The UE moves from a previous cell to a new cell. After the movement, the UE compares a public land mobile network (PLMN) identity indicating a PLMN to which the previous cell belongs, with a PLMN identity indicating a PLMN to which the new cell belongs. If the PLMN identity of the new cell is equal to the PLMN identity of the previous cell, the UE sets system information blocks that it has received and stored in the previous cell, as system information of the new cell. If the PLMN identity of the new cell is not equal to the PLMN identity of the previous cell, the UE receives system information blocks with ‘Area scopes Cell and PLMN’ from the new cell, considering that the system information for the previous cell will be invalid in the new cell.
