For ease of description, this method is illustrated as continuously.However, certain parts of this method can be held in other agreements or parallel Row (for example, simultaneously).This method may include following steps.
In S11, base station can determine whether user equipment (User Equipment, UE) meets the touching of measurement neighboring community Clockwork spring part.
In general, it is to fast move UE or UE to be located at service that the trigger condition of UE satisfaction measurement neighboring community, which includes UE, (serving) cell (i.e. the cell of base station control) edge.If UE meet in the two any one can be judged as it is full The trigger condition of foot measurement neighboring community.
UE is divided into according to the movement speed of UE and is fast moved and the mobile two kinds of UE of usual speed.No matter which kind of UE is in place Neighboring community is all probably moved to when serving cell edge, it is therefore desirable to be prepared for switching and be surveyed before carrying out cell switching Amount.In addition, for fast moving UE, if the measurement before the edge of serving cell just notifies that it carries out cell switching, UE have The coverage area that serving cell may have just been left before switching is completed leads to such as measurement delay, measurement report failure and cuts The generation for the problems such as changing unsuccessfully.For the appearance for avoiding this case, base station can be when judgement UE be in and fast moves state i.e. Think that the UE needs to carry out measurement before cell switching.
In S12, when UE meets the trigger condition of measurement neighboring community, base station can send measurement notice and first to UE The information of beam set.
