Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for utilizing a sequence number for two kinds of security functions in a wireless communications system. SOLUTION: The method includes the steps of: using a first sequence number in a first protocol entity as a parameter of a first security function; and using the first sequence number in a second protocol entity as a parameter of a second security function.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for detecting local NACKs, in a wireless communication system. SOLUTION: In the method for detecting local NACKs in wireless communication system, a local NACK signal is generated at the HARQ transmission end, when the HARQ transmission end relinguishes HARQ transmission due to expiration of timer.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for handling uplink data upon handover in a wireless communications system. SOLUTION: The method includes a content that upon handover of user equipment from a source base station to a target base station, the source base station transmits a message to the target base station. The message indicates values of sequence numbers of missing packets among packets transmitted from the user equipment to the source base station and a sequence number of a last received packet which the source base station receives from the user equipment.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of constructing packets that improves an existing packet format to allow many PDUs to be transmitted per logic channel per TTI, thereby enhancing the transmission efficiency of high-priority service data. SOLUTION: The method of constructing packets in a wireless communications system includes a step, wherein a plurality of group packet data units PDUs, corresponding to a logic channel, are concatenated at a transmission time interval TTI, and a plurality of data description signals are added to a transmission PDU during the TTI, where the plural data description signals, respectively correspond to the group PDUs and are fully or partially identical.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus of handling the variable of a RLC reset procedure during receiver-side-only reestablishment in a radio communications system. SOLUTION: The method includes resetting of a reset state variable, used for counting the number of times a reset PDU for RLC reset procedure initiation has been transmitted by an RLC entity, during receiver-side-only reestablishment.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for handling packets at a user end in a wireless communications system. SOLUTION: The method includes steps for: activating an HARQ procedure; receiving a first packet and decoding the first packet successfully; receiving a second packet following the first packet; and decoding the second packet if the second packet is the retransmission of the first packet.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for stopping a HARQ process which reduce signal transmissions of a network end and save radio resources in a radio communications system. SOLUTION: The method comprises: a step of receiving the message of a primary absolute grant which directs the stop of the first HARQ process; a step of making the first HARQ process stop; a step of starting all the HARQ processes, when all the HARQ processes are stopped, and when a secondary grant function is started; and a step of updating a transmission parameter by AG value specified by the secondary absolute grant (AG) message.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus of handling point-to-multipoint (p-t-m) MBMS services in order to prevent a wireless communications system from wasting system resource and power. SOLUTION: The method includes the step of adding an instruction into a message used for carrying information of the p-t-m MBMS service when the message is transmitted to a receiving terminal via a dedicated channel.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and related apparatus for stopping a point-to-multipoint (p-t-m) MBMS service by adding a step of releasing resources (RB) for receiving the p-t-m MBMS at a receiving terminal, deleting a channel for transmitting service data to surely stop reception of the service data so as to save system resources and power of the receiving terminal. SOLUTION: The method includes the following steps of deactivating the p-t-m MBMS service by the receiving terminal, updating a variable corresponding to the p-t-m MBMS service after the receiving terminal accomplishes a leaving session of the p-t-m MBMS service, and releasing a resource that is used for receiving the p-t-m MBMS service by the receiving terminal.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of managing media files received under different transmission modes and a media playback apparatus to solve various problems of conventional techniques. SOLUTION: The method of managing media files includes: receiving a media file; retrieving media information from the media file regardless of what transmission mode is used when the media file is received; and modifying a media information record corresponding to the media file according to the retrieved media information.
