Abstract
The present disclosure relates to a method, in a mobility function (MF) node. The method comprises receiving (S1) information about a mapping to a property, of each of a plurality of radio bearers of a radio device for carrying data traffic between the radio device and a first radio access network (RAN). The method also comprises determining (S2) based on the received (S1) information, that at least one of the radio bearers can be handed over to a second RAN. The method also comprises initiating (S3) a handover command to the radio device instructing the radio device to hand over the at least one radio bearer to the second RAN.
Claims15
A method, in a mobility function (MF) node, in a communication network, the method comprising:
- receiving information about a mapping to a property, of each of a plurality of radio bearers of a radio device for carrying data traffic between the radio device and a first radio access network (RAN);
- determining, based on the mapping, that at least one of the radio bearers can be handed over to a second RAN;
- and
- initiating a handover command to the radio device instructing the radio device to hand over the at least one radio bearer to the second RAN.
A mobility function (MF) node for a communication network, the MF node comprising:
- a communication interface configured for communicating with one or more nodes of at least a first radio access network (RAN);
- processing circuitry;
- and
- a storage unit storing instructions executable by said processing circuitry whereby said MF node is operative to:
- receive information about a mapping to a property, of each of a plurality of radio bearers of a radio device for carrying data traffic between the radio device and the first RAN;
- determine, based on the mapping, that at least one of the radio bearers can be handed over to a second RAN;
- and
- initiate a handover command to the radio device instructing the radio device to handover the at least one radio bearer to the second RAN.
