The present invention relates to a method of operating a radio access node (10) adapted to handle multiple bearers, a related radio access node (10), a method of operating a network control node (36) adapted to control the radio access node (10) handling multiple bearers, a communication system adapted to control multiple bearers, a computer program and a computer program product. Multiple bearers comprise a first packet switched bearer related to a voice service and at least one second packet switched bearer. Upon change of an operative condition for a first packet switched bearer a transfer of a voice service is initiated (S10) from the first packet switched bearer to a circuit switched bearer. This is followed by a decision (S12) on initiation of a handover for the second packet switched bearer, parallel to the transfer of the voice service, from a first packet switched access to a second packet switched access based on bearer control information indicating possibility of a parallel handover. The bearer control information is either pre- configured at the radio access node (10) or received from the network control node (36). |
