ADAPTING QOS FOR A RADIO BEARER HAVING TWO ASSOCIATED QOS BY MEANS OF A UE INDICATION

摘要

The present disclosure relates to a method performed in a UE radio device4Connected to a communication network1comprising a core network (CN)5and a Radio Access Network (RAN)2, e.g. eNB, where there is a communication bearer between the radio device and the CN via the RAN comprising a radio bearer11between the radio device and a RAN node3 of the RAN. The purpose of the method is to adapt a Quality of Service (QoS) of the communication bearer, and in particular of the radio bearer, depending on whether critical data or non-critical data is being transmitted. The UE sends to the eNB an indication of which QoS shall be applied to the radio bearer. The method comprises, to the CN, sending a request for a first QoS to be associated with the communication bearer. The method also comprises exchanging data over the radio bearer in accordance with the first QoS of the communication bearer. The method also comprises, to the RAN, sending by the UE radio device an indication that a second QoS, lower than the first QoS, should be used for the radio bearer. The method also comprises exchanging data over the radio bearer in accordance with the second QoS.
