Abstract
For monitoring and handling a radio link failure in inactive state, a method detects the radio link failure at a mobile communication device in the inactive state. The method further mitigates the radio link failure.
Claims17
A method comprising:
- detecting, by use of a processor, a radio link failure (RLF) at a mobile communication device in an inactive state;
- mitigating the RLF by:
- terminating uplink transmission;
- assigning a lowest frequency priority to a current frequency, wherein the assignment expires after a specified time interval;
- reselecting a base station;
- in response to a Non-Access Stratum (NAS) event, transmitting a Radio Resource Control (RRC) Connection Re-establishment Request message;
- and
- completing an RRC Connection Re-establishment procedure.

An apparatus comprising:
- a processor performing:
- detecting a radio link failure (RLF) at a mobile communication device in an inactive state;
- mitigating the RLF by:
- terminating uplink transmission;
- assigning a lowest frequency priority to a current frequency, wherein the assignment expires after a specified time interval;
- reselecting a base station;

6 more elements
A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
- detecting a radio link failure (RLF) at a mobile communication device in an inactive state;
- mitigating the RLF by:
- terminating uplink transmission;
- assigning a lowest frequency priority to a current frequency, wherein the assignment expires after a specified time interval;
- reselecting a base station;
- in response to a Non-Access Stratum (NAS) event, transmitting a Radio Resource Control (RRC) Connection Re-establishment Request message;
- and
- completing an RRC Connection Re-establishment procedure.
