Abstract
A method and arrangement in a Radio Network Controller (RNC) for monitoring radio link (RL) synchronization for each RL as soon as it is added to a User Equipment's (UE's) Active Set. When a new RL is added, each RL in the Active Set sends an Active Set Update Complete message to the RNC. When the RNC determines that a Radio Link Restore Indication message is not received from the Target NodeB serving the new RL, the RNC starts an initRlSyncT timer set for a defined time period and monitors incoming messages to determine whether the Radio Link Restore Indication message is received for the new RL before the initRlSyncT timer expires. If so, the method ends; but if not, the RNC instructs associated NodeBs and the UE to remove the new RL from the UE's Active Set.
