Abstract
The invention discloses a method and a device for processing the motion state of a mobile terminal, which are used for solving the technical problem that a UE judges the motion state of a user terminal incorrectly in the state of quick motion. The method and the device for processing the motion state of the mobile terminal take the times of changing cells in a certain time as a judgment criterion, wherein under the condition that an RRC is idle, the times of changing the cells comprise the times of reselecting the cells and the times of selecting the cells which are triggered by the user terminal entering a service area from an OOS state; and under the condition that the RRC is connected, the times of changing the cells comprise the times of switching the cells and the times of reestablishing the RRC connection successfully. The method and the device for processing the motion state of the mobile terminal improve the statistical method for the times of changing serving cells and make the motion state of the UE more accurate.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of processing method and device of motion state of mobile terminal.
Background technology
When user terminal (UE) away from former Serving cell gradually near the Target cell time, the process of gravity treatment or switching can take place, the incident assessment that reselection evaluation and triggering are switched all has certain duration, when the UE translational speed is very fast, may have little time to trigger gravity treatment/switching and cause the quality of Serving cell sharply to descend, thereby fall the phenomenon of net or call drop.Therefore the translational speed of UE is divided into a plurality of grades, when translational speed is high, reduces the evaluation time of gravity treatment/switching, accelerate gravity treatment/switching of UE.
(Long Term Evolution, LTE) in the system, the mobile status of UE is divided into three kinds: normal state, middling speed mobile status, high-speed moving state at Long Term Evolution.Idle state (RRC IDLE) down the gravity treatment number of times that takes place in certain hour of the differentiation of mobile status divide different grades.Connected state (RRC CONNECTED) down the number of times that switches in certain hour of the differentiation of mobile status divide different grades.
Under RRC IDLE attitude, if adjacent area service quality is good, then the sub-district gravity treatment can take place, if cover bad zone but just in time enter a block signal in the fast moving process, sub-district 4 as shown in Figure 1 and the regional location between the sub-district 5, then can cause UE to enter out of reach (Out Of Service, OOS) state, after continuing to move to the good zone of service quality, the flow process of cell selecting can take place, according to present statistical method, cell selecting this time can not be counted in the middle of the statistics that is used for grade classification, thereby can influence the accuracy that the UE mobile status is judged.
Under RRC CONNECTED attitude, when the UE fast moving, when causing also not having enough time to switch, Radio Link is failed, thereby trigger the flow process of RRC connection reconstruction, Serving cell also may become in the RRC process of reconstruction, but according to present statistical method, reconstruction can not be counted in the middle of the statistics that is used for grade classification, thereby also can influence the accuracy that the UE mobile status is judged.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of processing method and device of motion state of mobile terminal, be used to solve UE under high-speed motion state, Serving cell in the mobile status of UE is changed the not statistical uncertainty true of number of times, thereby influence is to the technological deficiency of the accuracy of UE mobile status judgement.
