Abstract

A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal connected to a mobile access network. A first Radio Access Bearer RAB is obtained, and the multimedia session is started by communicating media over the first RAB. Simultaneously with the media communication, a quality of communicated media is monitored and evaluated. If the monitored quality is deemed unacceptable, a media-adapted second RAB is obtained, and the session is continued over the second RAB. Thereby, it is not necessary to delay the communication of media by waiting for the second RAB to be obtained.
