Abstract

In a wireless mobile communications system, a method for transmitting and receiving a measurement report of a mobile terminal is provided. A network transmits a paging message to the mobile terminal for performing the measurement report or transmits a PDU (Protocol Data Unit) having segmented SDU (Service Data Unit). The mobile terminal transmits the measurement report upon receiving the paging message or the PDU having the segmented SDU, thereby utilizing a radio resource effectively.

Claims

1. A method of transmitting a measurement report of a mobile terminal in a wireless communications system, the method comprising:

receiving at least one PDU (Protocol Data unit) including a segmented SDU (Service Data Unit); and

determining whether or not to transmit the measurement report based on the segmented SDU included in the received at least one PDU,

wherein the measurement report is transmitted to a network when the segmented SDU cannot be reconfigured as a complete SDU into the at least one PDU or the measurement report is not transmitted to the network when the segmented SDU can be reconfigured as complete SDU into the at least one PDU, and

wherein the determining step is performed when the mobile terminal is in a specific state where the mobile terminal receives a downlink data including the segmented SDU while performing a DRX (Discontinuous reception).

2. The method of claim 1, wherein the at least one PDU is a MAC PDU and the segmented SDU is either a segmented MAC SDU or a segmented RLC SDU.

3. The method of claim 1, wherein the segmentation of the SDU is performed by a MAC (Medium Access Control) layer or a RLC (Radio Link Control) layer of a network.

4. The method of claim 1, wherein the at least one PDU is received via a HS-DSCH (High Speed Downlink Shared Channel).

5. The method of claim 1, wherein the measurement report is transmitted through a RACH (Random Access Channel).

6. A method of transmitting a measurement report of a mobile terminal, the method comprising:

receiving at least one PDU (Protocol Data unit) including a segmented SDU (Service Data Unit); and

selectively transmitting the measurement report to a network,

wherein the measurement report is transmitted to the network if the segmented SDU cannot be completely reconfigured or the measurement report is not transmitted to the network if the segmented SDU can be completely reconfigured, and

wherein the measurement report is transmitted when the mobile terminal is in a specific state that the mobile terminal receives a downlink data including the segmented SDU while performing a DRX (Discontinuous reception).
