Abstract
A network node receives (101) from a user equipment (UE), an indication of a mobility state of the UE. The network node utilizes (102) the mobility state of the UE to adapt a time to trigger (TTT) value for use in improved handover operation. Depending on the embodiment, the network node may also track handover failures (such as failures due to missing handover commands) and handover ping pongs and use this information to determine a TTT value that achieves a reduction in either a number of handover failures due to missing handover commands or a number of handover ping pongs or possibly both.
Claims20
A method comprising:
- receiving, by a network node from a user equipment (UE), an indication of a mobility state of the UE;
- utilizing, by the network node, the mobility state of the UE to adapt a time to trigger (TTT) value for use in improved handover operation.
A method comprising:
- sending, by a network node to a user equipment (UE), a request indication for mobility state information;
- receiving, by the network node from the UE in response to the request indication, an indication of a mobility state for the UE.
A method comprising:
- performing by a user equipment (UE) one of detecting the fulfillment of event A3 or receiving from a network node a request indication for mobility state information;
- sending, by the UE to the network node in response to the step of performing, an indication of a mobility state for the UE.
