Abstract
An apparatus, method and computer program is described including sending an addition request from a master node of a dual connectivity mobile communication system to a target secondary node of the dual connectivity mobile communication system, wherein each addition request includes information relating to a maximum number of primary secondary cells that can be prepared for primary secondary cell change by said target secondary node; and receiving a response to the addition request from the target secondary node indicating how many primary secondary cells have been prepared by said target secondary node in response to said addition request.
Claims24
An apparatus, comprising means for performing:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
- sending an addition request from a master node of a dual connectivity mobile communication system to a target secondary node of the dual connectivity mobile communication system, wherein the addition request includes information relating to a maximum number of primary secondary cells that can be prepared for primary secondary cell change with said target secondary node;
- and
- receiving a response to the addition request from the target secondary node, wherein said response indicates how many primary secondary cells have been prepared with said target secondary node in response to said addition request.
An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
- receiving an addition request from a master node of a dual connectivity mobile communication system at a target secondary node of the dual connectivity mobile communication system, wherein the addition request includes information relating to a maximum number of primary secondary cells that can be prepared for primary secondary cell change with said target secondary node;
- determining which of one or more available primary secondary cells of the target secondary node to prepare for primary secondary cell change;
- and
- sending an indication to the master node indicating how many primary secondary cells have been prepared with said target secondary node in response to said addition request.
An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
- sending a change required message from a source secondary node to a master node of a dual connectivity mobile communication system, wherein the change required message provides information relating to a maximum number of primary secondary cells that can be prepared for primary secondary cell change with a target secondary node.
