Abstract

The invention discloses a method for eliminating ABS (almost blank subframe) circumvention and a device thereof. The method comprises the following steps: when a user terminal configures ABS circumvention, the user terminal records signal intensity A0 of an interference cell and/or signal intensity B0 of an interfered cell; the user terminal measures signal intensity Ak of the interference cell and/or signal intensity Bk of the interfered cell; when a difference between the signal intensity A0 and the signal intensity Ak reaches a threshold AS, and/or a difference between the signal intensity Bk and the signal intensity B0 reaches a threshold BS, the user terminal eliminates the ABS circumvention. In an embodiment of the invention, the user terminal records the signal intensity of the interference cell and/or the signal intensity of the interfered cell after configuration of the ABS circumvention, according to the recorded signal intensity, the user terminal determines whether to leave an interference area or not and determines to eliminate the ABS circumvention after leaving the interference area, thus measuring and scheduling behaviors before configuration of the ABS circumvention can be recovered.

Description

Eliminate the method and apparatus that ABS evades
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus that a kind of ABS of elimination evades.
Background technology
Along with the requirement of growing data rate and business load, traditional covering with the macro base station individual layer provides the method for access can not satisfy the demands.The employing layering covers, and in hot zones or some lower powered base stations of indoor deployment, for example Home eNodeB (Home eNodeB), Pico (little) base station, Femto (little) base station, Relay (relaying) can be good at addressing this is that.This lower powered base station is a kind of base station equipment that is applied under family's indoor environment, working environment or the little overlay environment of other focus, can make operator that high data rate, attractive business more cheaply are provided more.
But there is certain restriction the Femto base station to the Member Users who inserts, and non-Member Users can not insert; If non-Member Users gets into the coverage of this Femto base station; Then non-Member Users need dispose ABS (Almost Blank Subframe, near-space white chessman frame) and evade, to continue to stay the base station that can insert; Otherwise can cover cavity (Coverage Hole) owing to the low power base station signal gets into by force, cause non-Member Users not work.If Pico base station and macro (grand) base station is in frequently, the UE the Pico base station under may receive the interference of macro signal of base station and cisco unity malfunction, and UE need dispose ABS equally to be evaded and solve interference problem.Wherein, UE configuration ABS evades and refers to UE and only on the ABS of network notice, measuring and transfer of data.
For example, UE1 belongs to macro base station among Fig. 1, and the Femto base station only can authorization of service CSG (Close Subscriber Group, Closed User Group) user.When UE1 is positioned at the coverage of Femto base station; Because UE1 is not the CSG user's (being that UE1 is non-Member Users) who authorizes; Even the Femto signal strength signal intensity is higher than the signal strength signal intensity of macro base station far away; UE1 also can't switch to the Femto base station and will receive the strong jamming from the Femto base station, thereby causes the non-constant of channel condition of UE1, even can't work.Solve above-mentioned interference problem through evading in the prior art at UE1 configuration ABS.Because there is strong jamming the Femto base station to macro base station, can use ABS to evade in the Femto base station, between macro base station and Femto base station, coordinate sub-frame allocation by network side.UE1 configuration ABS evades, and only on the ABS of network notice, measures and transfer of data.Because the Femto base station stops the scheduling of data field on ABS, only send the CRS signal, thereby can not produce strong jamming to UE, UE can normally measure original Serving Cell (Serving cell), i.e. macro base station, and keep with the normal of former Serving cell and be connected.
For the interference problem of Pico base station and macro base station, adopt the ABS Hedging mechanism to solve equally.The UE that for example belongs to the Pico base station receives macro base station disturb after, UE configuration ABS evades, and only on the ABS of network notice, measures and transfer of data.Because macro base station stops the scheduling of data field on ABS, therefore, UE can avoid receiving the interference of macro base station.
As shown in Figure 2; Be in harmonious proportion Femto base station, macro base station and conflicted though ABS evades scheme with interference between the Pico base station; Make that UE is able to operate as normal under the strongly disturbing situation is being arranged originally; But owing to carried out the restriction on the time domain subframe, UE can be scheduled and the chance of measuring will reduce greatly in this case.If UE leaves interference region, for example, the UE that belongs to macro base station leaves the coverage of Femto base station, and then UE no longer is interfered.But UE can not eliminate ABS automatically and evades in the prior art, use ABS evade scheme after UE will only on ABS, measure and transfer of data always, cause UE can't recover normal and measure and the scheduling behavior.
