Abstract:
A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.
