Handling of Measurement Configuration Upon Conditional Mobility Execution

A method for conditional mobility in a radio access network (RAN), wherein the method is performed by a user equipment (UE) and comprises:

• receiving, from one or more RAN nodes, one or more mobility-related messages comprising:
• a first indication of a mobility operation,
• a second indication of a triggering condition for the mobility operation,
• a second measurement configuration related to the triggering condition, and
• a third measurement configuration related to one or more target cells, to be applied after execution of the mobility operation;
• based on the second measurement configuration, detecting fulfillment of the triggering condition with respect to a particular one of the target cells and executing the mobility operation towards the particular target cell;
• and
• subsequently performing and reporting third measurements in the particular target cell based on the third measurement configuration.

A method for conditional mobility of a user equipment (UE) in a radio access network (RAN), wherein the method is performed by a source RAN node and comprises:

• sending, to a target RAN node, a request to accept a mobility operation related to the UE;
• receiving, from the target RAN node, a confirmation of the mobility operation, the confirmation including a third measurement configuration related to one or more target cells served by the target RAN node, the third measurement configuration to be applied by the UE after an execution of the mobility operation;
• determining a second measurement configuration related to a triggering condition for the mobility operation;
• and
• sending, to the UE, a mobility-related message comprising:
• a first indication of the mobility operation;
• a second indication of the triggering condition;
• the second measurement configuration;
• and
• the third measurement configuration,
• wherein the second and third measurement configurations include respective measurement configurations for each target cell that is a candidate for the mobility operation indicated by the first indication.

A method for conditional mobility of a user equipment (UE) in a radio access network (RAN), wherein the method is performed by a target RAN node and comprises:

• receiving, from a source RAN node, a request to accept a mobility operation related to the UE, the request including a first measurement configuration for the UE;
• based on the first measurement configuration, determining a third measurement configuration for the UE in relation to one or more target cells served by the target RAN node, wherein the third measurement configuration is to be applied by the UE after execution of the mobility operation;
• sending, to the source RAN node, a confirmation of the mobility operation, the confirmation including the third measurement configuration;
• and
• receiving, from the UE, measurements made in a particular one of the target cells based on the third measurement configuration.
