Patent ID: 8731563

Claim:
A method for reporting a mobility state of a mobile terminal comprising: A User Equipment (UE) in an idle state evaluating its own mobility state based on a first evaluation parameter sent by an evolved Node B (eNodeB) through system broadcast before the UE enters into a Radio Resource Control (RRC) connection state, and obtaining an evaluated first determination result; and the UE reporting the first determination result to the eNodeB through a RRC connection setup complete message during setting up a RRC connection; wherein the UE evaluating its own mobility state based on the first evaluation parameter and obtaining the first determination result comprises: the UE obtaining a number of times for the UE to change cells in preset time periods of T CRmax of a third timer and T CRmaxHyst of a fourth timer, respectively, and comparing the obtained number of times with a preset second lower limit time N CR M and second upper limit time N CR H ; when the number of times for the UE to change cells in the time period of T CRmax is greater than the N CR M and less than or equal to the N CR H , determining that the UE is in a medium speed mobility state; when the number of times for the UE to change cells in the time period of T CRmax is greater than the N CR H , determining that the UE is in a high speed mobility state; and when the number of times for the UE to change cells in the time period of T CRmaxHyst is less than or equal to the N CR M , determining that the UE is in a normal mobility state.
