Abstract

Disclosed is the radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to a method of transmitting an aggregated measurement report to a network in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from the Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

Claims

1. A method of performing a measurement report in wireless communication system, the method comprising:

receiving, from a network, a parameter indicating a measurement report configuration;

measuring a radio environment after receiving the parameter, wherein the measured radio environment is not yet reported to the network;

storing the radio environment measurement;

repeatedly performing the steps of measuring and storing until a certain condition is met;

aggregating at least two or more stored radio environment measurements; and

reporting the aggregated radio environment measurements to the network.

2. The method of claim 1, wherein a certain number of the most recently measured radio environments are only stored.

3. The method of claim 2, wherein the certain number is received from the network via a broadcast signaling or a dedicated signaling.

4. The method of claim 1, wherein the parameter indicating the measurement report configuration is received from the network periodically or non-periodically.

5. The method of claim 1, wherein the aggregated radio environment measurements are aggregated in an order of measuring time.

6. The method of claim 1, wherein the radio environment is measured in a RRC_IDLE mode.

7. The method of claim 1, wherein the received parameter indicates a total number of measurements that should be performed by a terminal.

8. The method of claim 7, wherein the certain condition is met when a total number of measuring steps performed by the terminal is equal to the total number of measurements indicated in the received parameter.

9. The method of claim 8, further comprising:

establishing a RRC (radio resource control) connection with the network after the certain condition is met.

10. The method of claim 1, wherein the measured radio environment represents at least one of a radio quality for a cell providing a service, a radio quality for a neighboring cell, a cell identity, closed subscriber group (CSG) membership information, and broadcast information of other cell.

11. The method of claim 1, wherein the measured radio environment is specific information among broadcast information of a cell, and the specific information is instructed by the network to be read.

12. The method of claim 1, wherein the radio environment measurements are aggregated with information indicating a time and place for a corresponding measurement.

13. The method of claim 1, wherein the aggregated radio environment measurement is reported based on a radio environment measurement report condition.

14. The method of claim 13, wherein the radio environment measurement report condition is at least one of a network'"'"'s indicated number, absolute time, a network demand, a periodical timer, a terminal memory usage and a position of terminal.
