The structural representation of a kind of Inter-Cell Interference Coordination device that Fig. 2 provides for the embodiment of the invention two.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
The schematic flow sheet of a kind of inter-cell interference coordination method that Fig. 1 provides for the embodiment of the invention one, as shown in Figure 1, described method comprises:
101, determine the high interference business of high interference Physical Resource Block and described high interference Physical Resource Block correspondence, described high interference business is the current loaded service of described high interference Physical Resource Block;
102, whether the quality of service QoS grade that detects described high interference business reaches the default professional corresponding standard QoS grade of described high interference, if then do not send to adjacent base station and disturb the overload alarm.
Wherein, the executive agent of present embodiment can be the Inter-Cell Interference Coordination device, and described Inter-Cell Interference Coordination device can be arranged on the base station.In actual applications, the base station is described traffic assignments Physical Resource Block, and stores the corresponding relation of the sign of described service identification and described Physical Resource Block according to the service request that comprises professional service identification.Therefore, in the present embodiment, described Inter-Cell Interference Coordination device can be determined the current loaded service of described high interference Physical Resource Block according to the sign corresponding service sign of each Physical Resource Block of current storage in its base station, place behind definite high interference Physical Resource Block.
Optionally, in a kind of embodiment of present embodiment, after whether the quality of service QoS grade that detects described high interference business described in 102 reaches the default professional corresponding standard QoS grade of described high interference, can also comprise:
If the QoS grade of described high interference business does not reach the professional corresponding standard QoS grade of described high interference, then send the alarm of described interference overload to described adjacent base station.
Wherein, describedly send the alarm of described interference overload to described adjacent base station and specifically can comprise: by X2 interface, send the alarm of described interference overload to described adjacent base station.
Concrete, the alarm of described interference overload can include but not limited to the sign of described high interference Physical Resource Block.Described adjacent base station is adjusted self edge customer corresponding physical Resource Block according to the alarm of described interference overload and is specifically as follows, described adjacent base station is according to the described interference overload alarm that receives, avoid the Physical Resource Block that himself has like-identified is distributed to the edge customer that is in its edge customer in himself base station and described base station overlapping covered, thereby avoid presence of intercell interference.Its relevant concrete scheme does not repeat them here.
In this embodiment, if high interference Physical Resource Block loaded service does not reach preset requirement because presence of intercell interference influences its quality of service, then carry out the scheme of Inter-Cell Interference Coordination, effectively improve the low excessively situation of quality of service that causes because of presence of intercell interference.
In actual applications, the state of Physical Resource Block mainly comprises uplink state and downstream state.Further, if the current state of described Physical Resource Block is uplink state, then be used for judging whether it is the parameter of high interference Physical Resource Block, be that the uplink interference parameter mainly comprises: high interference indication (High Interference Indication, be called for short HII) parameter and overload indication (Overload Indication is called for short OI) parameter; If the current state of described Physical Resource Block is downstream state, then be used for judging whether it is the parameter of high interference Physical Resource Block, it is that descending interference parameter mainly comprises: narrow emission power indication (Relative Narrowband TX Power is called for short RNTP).Concrete, if the currency of arbitrary above-mentioned parameter greater than its corresponding preset threshold value, determines that then described Physical Resource Block is the high interference Physical Resource Block.
Concrete, in above-mentioned arbitrary execution mode, because the signal that the object of presence of intercell interference is generally between the Cell Edge User disturbs, then optional, described definite high interference Physical Resource Block specifically can comprise:
Obtain the current state of edge customer corresponding physical Resource Block;
If the current state of described Physical Resource Block is uplink state, then obtain the currency of the uplink interference parameter of described Physical Resource Block;
If the currency of arbitrary described uplink interference parameter, determines then that described Physical Resource Block is described high interference Physical Resource Block greater than default described uplink interference parameter corresponding threshold;
If the current state of described Physical Resource Block is downstream state, then obtain the currency of the descending interference parameter of described Physical Resource Block;
If the currency of described descending interference parameter, determines then that described Physical Resource Block is described high interference Physical Resource Block greater than default described descending interference parameter corresponding threshold.
Wherein, described edge customer is the user who is in the edges cover zone of base station.The described current state of obtaining edge customer corresponding physical Resource Block can be for obtaining or regularly obtain the current state of described edge customer corresponding physical Resource Block in real time.
Need to prove, the concrete grammar of described definite high interference Physical Resource Block includes but not limited to above-mentioned execution mode, its method of determining the high interference Physical Resource Block also can be the method that other determines the high interference Physical Resource Block, and present embodiment does not limit it at this.
