Abstract: Method and network entities for providing good performance for voice in multiRAB connection for services of a CS+PS call setup (31) without high throughput necessity but providing good throughput for the services needing it. A differentiation of the multiRAB configuration (bearer type, mobility parameters and channel switching timers), based on service detection, is performed either in the RAN either in the CN indicating eventually this detection to the RAN. If the detected service needs high bit rate/throughput (35), the RNC reconfigures the multiRAB configuration (37) so that a bearer type providing high throughput is allocated to said service and the RNC reassigns mobility and channel switching parameters to maximise this throughput and the radio resources. If the service does not require high throughput (34), the RNC configures a bearer type and parameters for mobility and channel switching as specified by the standards to provide good performance (36), low dropped call rate.
