Cell reselection or switching and cause serving cell radio channel state drastically decline occur RLF produce fall net or call drop phenomenon.
In order that the UE for obtaining mobile status preferably adapts to fast-changing wireless environment, the shifting that mobile status is used to reflect UE is introduced
Dynamic speed speed.UE mobile status one is divided into three kinds：Normal mobile state (normal-mobility state), middling speed
Mobile status (medium-mobility state), high-speed moving state (high-mobility state).Base station, which passes through, is
System broadcast message (idle (IDLE) state) or RRC (Radio Resource Control, wireless heterogeneous networks) proprietary signaling (connect
Connect state) by for judging that the series of parameters of mobile status is sent to UE.It is right in certain time length that UE can be based on the judgement parameter
The cell change number undergone is counted to estimate its mobile status, and cell change number includes cell reselection number
(IDLE states) and switching times (connected state).IDLE states UE can adjust corresponding cell reselection phase according to the mobile status of its estimation
Related parameter；Connected state UE can be adjusted according to the mobile status of its estimation and be triggered relevant parameter for the measurement event of switching, work as UE
Translational speed can be reduced when higher cell reselection or for switching measurement event trigger the assessment time, accelerate cell reselection or
Switching is completed.
HetNet (Heterogeneous Network, heterogeneous network) refers to that low power nodes are placed on macro base station by cloth and covered
In cover area, the heterogeneous system of the different node types with covering is formed.LPN (Low Power Node, low power nodes) is wrapped
Include micro-base station (Micro), femto base station (Pico), RRH (Remote Radio Head, long distance wireless connection), via node

Point be exactly in heterogeneous network each cell coverage area difference in size it is very big.
Disposed under heterogeneous network, while all kinds low power nodes, and the footprint size difference of cell is very
It is different.By UE only considers undergone cell change number to move state estimation in the prior art, without considering to be passed through
The cell type and arrangement situation gone through, it is thus possible to cause small by what is undergone on mobile route with the UE of constant speed movement
Area's type is different and detects different mobile status, namely UE can not accurately move state estimation, it is impossible to well
Adapt to the change of current radio channel conditions.Specifically, it is mobile under the intensive network environment of Femto/Pico cell arrangements
In UE more frequently cell reselection or Femto cells (cell) or Pico cell will be switched to.According to prior art
Mobile status estimate, then UE may mistake detection its be in high-speed moving state.The high-speed mobile shape that then UE estimates according to it
State reduces cell reselection relevant parameter Treselection or the measurement event for switching triggers relevant parameter
TimeToTrigger values, mobile robustness is reduced, cause to cut caused by the ping-pong effects of switching or switching are too early
Change unsuccessfully.
