UE based on the measurement and reporting MDT after a crash radio link to the cellular radio access network

摘要

1. A method of communication by a user device (UE) (1) measurement information in the radio network (3), where the UE performs steps comprising making measurements to minimize operational test (MDT) for communication in a radio communication network, the method being characterized in that it comprises the steps of: detecting a failure at MDT measurement information message; failure to retain information MDT measurement, detect a radio link failure; initiate establishment or re-establishment of the radio link with the radio access network and inform the network rad iosvyazi of stored information measurement MDT; and transmitting a radio message of a radio link network failure (RLF), which also includes at least a portion of the stored information unreported MDT.2 measurements. A method according to claim 1, wherein when a re-initiating the radio link: the radio network is transmitted in a re-request message a radio resource control protocol (RRC); transmitting the report of the completion of the RRC connection re-specify the availability of reports RLF.3. A method according to claim 1, wherein the measurement information is information MDT MDT, measured during the stay in the UE mode MDT.4 immediate messages. A method according to claim 1, wherein the MDT measurement information is information MDT, measured during the stay in the UE mode MDT posts by registration zhurnalu.5. A method according to claim 1, wherein the RLF message includes information RLF, different from the stored information unreported MDT.6 measurements. A method for a network node (100) in a wireless communication network (3) comprising the steps of: receiving from the UE (1, 120) over a radio link, one or bo
