Abstract
New Radio (NR) RRC includes an RRC_INACTIVE state, which introduces ambiguities in the network's knowledge of UE behavior. A mechanism is introduced for handling parameters received when a UE enters RRC_INACTIVE or RRC_IDLE upon the UE attempting to resume an RRC connection and, as a response, receiving a Release or Suspend message. The timer associated to the mobilityControlInfo (equivalent to T320) is stopped and associated parameters are discarded upon receiving RRC Release or Suspend. Information received in a Release or Suspend message is discarded upon receiving RRC Release or RRC Suspend.
Claims7
A method of managing Radio Resource Control (RRC) states, performed by a wireless device operative in a wireless communication network, the method is characterized by:
- while in an RRC_INACTIVE state, and performing activities associated with dedicated cell reselection priority information stored at the wireless device, sending an RRC message to the network requesting to enter an RRC_CONNECTED state;
- receiving, in response to the RRC message requesting to enter an RRC_CONNECTED state, an RRC message from the network directing the wireless device to enter an RRC_IDLE state or to remain in RRC_INACTIVE state;
- and
- in response to the received RRC message and if the received RRC message does not include dedicated cell reselection priority information,
- discarding the stored dedicated cell reselection priority information;
- and
- discontinuing the activities associated with the dedicated cell reselection priority information;
- wherein performing activities associated with dedicated cell reselection priority information comprises performing cell reselection according to dedicated priorities while a validity timer of the cell reselection priority parameter is running.
A wireless device operative to manage Radio Resource Control (RRC) states, while operative in a wireless communication network, the wireless device adapted to:
- while in an RRC_INACTIVE state, and performing activities associated with dedicated cell reselection priority information stored at the wireless device, send an RRC message to the network requesting to enter an RRC_CONNECTED state;
- receive, in response to the RRC message requesting to enter an RRC_CONNECTED state, an RRC message from the network directing the wireless device to enter an RRC_IDLE state or to remain in RRC_INACTIVE state;
- and
- in response to the received RRC message and if the received RRC message does not include dedicated cell reselection priority information,
- discard the stored dedicated cell reselection priority information;
- and
- discontinue the activities associated with the dedicated cell reselection priority information;
- wherein performing activities associated with dedicated cell reselection priority information comprises performing cell reselection according to dedicated priorities while a validity timer of the cell reselection priority parameter is running.
