Methods for Cancelling or Update of Conditional Mobility Procedures

A method, performed by a first network node in a radio access network (RAN) for mobility of a user equipment (UE) served by a second network node in the RAN, the method comprising:

• receiving, from the second network node, a request for a mobility procedure for the UE in relation to at least one candidate target cell associated with the first network node;
• determining if the UE can be accepted for the requested mobility procedure and, if the UE can be accepted, allocating resources to support mobility of the UE;
• transmitting, to the second network node, a response that includes a configuration for the mobility procedure and that indicates the UE can be accepted unless a cancelling message is subsequently received from the second network node;
• determining that the configuration is no longer valid;
• and
• transmitting, to the second network node, an indication that the configuration is no longer valid.

• transmitting the configuration to the UE;
• receiving, from the first network node, an indication that the configuration is no longer valid;
• and
• reconfiguring the UE based on the indication.
