Currently, in the current mechanism of LTE, the mobile status of user terminal (UE) is divided into three kinds of high speed, middling speed and low speed, i.e., High mobile status (High-mobility state), medium mobile status (Medium-mobility state) and normal shifting Dynamic state (Normal-mobility state).

When UE is in Idle state, number of the judgement based on cell reselection of several mobile status, the specific method is as follows：

1) mobile status detection criteria：

Medium mobile status：In T_CRmaxIn period, cell reselection number is more than N_{CR_M}, but it is not above N_{CR_H}。

High mobile status：In T_CRmaxIn period, cell reselection number is more than N_{CR_H}。

Otherwise, if the criterion of medium mobile status is detected, UE enters medium mobile status；

Otherwise, if in time T_CRmaxHystInterior, the criterion of high or medium mobile status is not detected, then UE enters normal mobile state；

Wherein, T_CRmax：The time of cell reselection/switching times is executed for assessing UE.

N_{CR_M}：UE enters the cell reselection/switching times reached needed for medium mobile status.

N_{CR_H}：UE enters the cell reselection/switching times reached needed for high mobile status.

T_CRmaxHyst：UE needs the additional assessment time met before entering normal mobile state.

And it is similar with the UE of idle state to the mobile status judgment mode of the UE of connection status, there is the following different：

1) switching times are used to replace cell reselection number；

2) the judgement parameter provided in dedicated signaling is provided, rather than in system message, it is as follows：

Include parameter T in the system broadcasts of the current persistent districts UE_CRmax,N_{CR_H},N_{CR_M}And T_CRmaxHyst, for the free time UE mobile status detection when state；Include parameter T in the dedicated signaling of UE_CRmax,N_{CR_H},N_{CR_M}And T_CRmaxHyst, for carry out Mobile status detection when connected state.

Above-mentioned judgement parameter T_Crmax、N_{CR_M}、N_{CR_H}、T_CRmaxHystCan then above-mentioned movement speed grade be used as to judge auxiliary Information, user judge the movement speed grade of user terminal.
