As shown in Figure 5, the present embodiment provides the disturbance coordination method in a kind of Long Term Evolution LTE system, comprises the following steps:
Near S301: have base station eNB monitors after other eNB, obtain the type of other eNB the distance of definite other eNB and this base station eNB;
Wherein, this base station eNB is determined the distance of other eNB and this base station eNB by technology such as global position system GPS technology or LBS (Location Based Service, shift position service).
S302: this base station eNB, after the judgement type of other eNB is different with the type of this base station eNB, compares the distance of described other eNB and this base station eNB and predetermined threshold value;
By comparing the distance of other eNB and this base station eNB, can judge whether UE under this base station eNB management is interfered or whether this base station eNB has disturbed the UE under other eNB, if distance is less than predetermined threshold value, can judge this base station is interference source or disturbed side.
S303: if when described distance is less than predetermined threshold value, enable ABS function.
Wherein, if described distance is less than predetermined threshold value, this base station eNB further judges that the UE under this eNB can be subject to the interference of other eNB, or this base station eNB can be disturbed the UE of other eNB management; Because the transmitting power of macro base station is much larger compared with LPN (as micro-(Pico) community, Home eNodeB (femto) community etc.), and power is also different separately in each community, and interference will be caused to low power community in powerful community.For example, if macro base station monitors other LPN, macro base station can disturb the UE under other base stations, and if LPN monitors macro base station, LPN can be subject to the interference of macro base station.

2, there is X2 interface: can mutually notify by the LOAD INFORMATION message in X2 interface the configuring condition of two base station ABS subframes.
Below, in an application example, the interference scene while take Macro eNB and Femto eNB mixed networking is example, eNB and UE, with GPS function, are described in further detail above-described embodiment:
One, Femto eNB disturbs the descending interference scene of non-CSG (Closed Subscriber Group, closed user group) Macro eNB UE
Non-CSG Macro UE swarms into Femto eNB coverage, and owing to cannot being switched to Femto eNB, thereby Femto eNB can produce descending interference to this UE, need to enable ABS and avoid interference, and specifically comprises the following steps:
S401:Macro UE utilizes GPS to orient near Femto eNB, gets Femto relevant information, comprises distance, base station type etc., and UE passes to service Marco eNB by this information;
S402:Macro eNB receives after the GPS information that Femto is relevant, according to default distance threshold, judge whether UE is interfered, if judgement is interfered, Macro eNB side is enabled ABS function, that is, Macro eNB dispatches non-CSG Macro UE and uses pre-configured ABS subframe transmission downlink data;
S403: S402 is corresponding with step, Femto eNB utilizes GPS to orient Macro UE, obtains the relevant information of this UE, comprises distance, affiliated service station etc., according to predeterminable range thresholding, judge whether can this UE be produced and be disturbed, if produced, disturb, Femto eNB side be enabled ABS function,, Femto eNB vacates this pre-configured ABS subframe, that is, the UE of Femto eNB management does not send downlink data in described ABS subframe.
Two, Macro eNB disturbs the descending interference scene of Femto eNB UE
When Femto eNB is nearer apart from Macro eNB, the signal of Macro is comparatively strong, can cause stronger interference to Femto user descending, now also needs to enable ABS function and avoids interference, and specifically comprises the following steps:
S501:Macro eNB utilizes GPS to orient near Femto eNB, gets the relevant information of this Femto, comprises distance, type etc.;
S502:Macro eNB judges whether to cause interference to the UE under this Femto according to this information, if can cause interference, Macro eNB side is enabled ABS function.
S503: corresponding with S502, Femto eNB utilizes GPS to orient Macro eNB, gets the relevant information of Macro, comprise distance, type etc., according to this information Femto, judge whether to be subject to the interference from Macro, if can be interfered, Femto eNB side is enabled ABS function.
The principle of enabling ABS function is, disturb source side to vacate an ABS subframe, the side of being disturbed is used this ABS subframe, scheduling UE is used this ABS subframe to send downlink data, in this application example, disturbing source side is Macro eNB, so in step S502, Macro eNB vacates an ABS subframe; The side of being disturbed is Femto eNB, so in step S503, Femto eNB is used this ABS subframe, scheduling UE is used this ABS subframe to send downlink data.
From above-described embodiment, can find out, with respect to prior art, disturbance coordination method, base station and system in the LTE system providing in above-described embodiment, adopt brand-new mode to judge interference scene, changed the dependence to UE or eNB measurement capability, and what utilize is comparatively general GPS technology, has evaded because measurement data is forbidden the false judgment of bringing.
