Abstract
A method and apparatus of reporting logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives Minimization of Drive Tests (MDT) configuration from a base station and starts a validity timer upon receiving the MDT configuration. The user equipment in an RRC idle mode logs measurements based on the MDT configuration to collect logged measurements while the validity timer is running. When the validity timer is expired, the user equipment discards the MDT configuration.
Claims14
A method of reporting logged measurements of a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, by a user equipment (UE), a Minimization of Drive Tests (MDT) measurement configuration message;
- upon receiving the MDT measurement configuration message, initiating, by the UE, a release of current MDT measurement configuration message;
- upon receiving the MDT measurement configuration message, starting, by the UE, a validity timer;
- and
- performing, by the UE, a logging of measurement while the UE is in a Radio Resource Control (RRC) idle mode based on the MDT measurement configuration message while the validity timer is running;
- when the validity timer is stopped, discarding, by the UE, the MDT measurement configuration message.
An apparatus of reporting logged measurements in a wireless communication system, the apparatus comprising:
- a radio frequency unit for transmitting and receiving radio signals;
- and
- a processor operatively coupled with the radio frequency unit and configured for:
- receiving a Minimization of Drive Tests (MDT) measurement configuration message;
- upon receiving the MDT measurement configuration message, initiating a release of current MDT measurement configuration message;
- upon receiving the MDT measurement configuration message, starting a validity timer;
- and
- performing a logging of measurement while the UE is in a Radio Resource Control (RRC) idle mode based on the MDT measurement configuration message while the validity timer is running;
- when the validity timer is stopped, discarding the MDT measurement configuration message.
