摘要:
The present disclosure relates to methods and arrangements for re-establishing packet data transfer between a radio base station and a wireless device following radio link failure, the radio base station having pre-configured wireless device information. The RBS receives a request for re-establishment of the radio link from the wireless device. One or more DRBs are selected for re-establishment based on the pre-configured wireless device information. The RBS transmits a radio link re-establishment response to the wireless device comprising information about the selected one or more DRBs. The selected one or more DRBs are re-established upon receipt of a re-establishment confirmation from the wireless device, whereupon packet data transfer is resumed.
