First Claim
Patent Images
1. A method in a user equipment of reporting information for observing performance of random access in a cellular radio system, the method comprising:
- storing data needed to compute measurements that are to be reported and that are associated with a most recent random access procedure performed by the user equipment;
computing said measurements;
generating a measurement report for said measurements to include an indication of whether a contention has occurred during said most recent random access procedure;
receiving a direct request from a radio base station for said measurement report responsive to said most recent random access procedure being successful; and
transmitting the measurement report responsive to said request.

Abstract
A user equipment for obtaining data for observing performance related to Random Access in a cellular radio system is provided. The user equipment can connect to the system. In order to provide the network/system with data for observing the random access procedure the user equipment measures and stores data needed to compute measurements to be reported to the system. The user equipment further generates a measurement report, and transmits the measurement report based on a trigger event.

16. A user equipment configured to report data from which performance related to random access in a cellular radio system can be observed, the user equipment comprising:
a processor and a memory, said memory containing instructions executable by said processor whereby the user equipment is configured to; store data needed to compute measurements that are to be reported and that are associated with a most recent random access procedure performed by the user equipment; compute said measurements; generate a measurement report for said measurements to include an indication of whether a contention has occurred during said most recent random access procedure; receive a direct request from a radio base station for said measurement report responsive to said most recent random access procedure being successful; and transmit the measurement report responsive to said request. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
- 27. A radio base station configured to obtain data from a user equipment for observing performance related to Random Access in a cellular radio system, the radio base station comprising a transceiver configured to transmit to the user equipment a direct request for a measurement report responsive to the user equipment'"'"'s most recent random access procedure being successful, and, responsive to said request, receive from the user equipment reported data of measurements that have been performed by the user equipment and that are associated with said most recent random access procedure, wherein the reported data includes an indication of whether a contention has occurred during said most recent random access procedure.
