Monitoring of radio link synchronization in a user equipment's active set

A Radio Network Controller (RNC) configured to monitor radio link (RL) synchronization in a user equipment's active set having a plurality of RLs, the RNC comprising:

• a non-transitory memory for storing computer program instructions;
• a processor coupled to the memory and configured to control the RNC when executing the computer program instructions, wherein the processor controls:
• a RL addition unit configured to add a new RL to the user equipment's active set;
• a confirmation unit configured to detect that the new RL did not synchronize within a defined time period;
• and
• a RL removal unit configured to remove the new RL from the user equipment's active set in response to the confirmation unit detecting that the new RL did not synchronize within the defined time period.

A computer program product comprising software instructions stored on a non-transitory, computer-readable medium in a Radio Network Controller (RNC), wherein when the software instructions are executed by one or more processors, the RNC is caused to monitor radio link (RL) synchronization in a user equipment's active set having a plurality of RLs by performing the following:

• adding a new RL to the user equipment's active set;
• detecting that the new RL did not synchronize within a defined time period;
• and
• removing the new RL from the user equipment's active set in response to detecting that the new RL did not synchronize within the defined time period.
