It is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Embodiment one:
The embodiment of the present invention one provides a kind of interference adjacent area and determines method, as shown in Fig. 2, it is the embodiment of the present invention one
The flow diagram of the method, the method can comprise the following steps that
Step 201: obtaining the signal level of each neighboring community for its place main serving cell that terminal receives.
Specifically, in embodiment of the present invention, the executing subject of each step can be RNC (Radio Network
Controller, radio network controller) or network side equipments, the embodiment of the present invention such as base station this is not limited in any way.
Further, the network side equipment can obtain the end by way of carrying out information exchange with the terminal
The signal level of each neighboring community of main serving cell where terminating the terminal received.Wherein, the signal level is available
The intensity of the signal received in description wireless communication system.Such as, when the wireless communication system is TD-SCDMA system,
The signal level may refer to RSCP (Received Signal Code Power, received signal code power) value, when described
When wireless communication system is TD-LTE system, the signal level may refer to RSRP (Reference Signal
Receiving Power, Reference Signal Received Power) value, the embodiment of the present invention is not limited in any way this.
Further, it should be noted that the targeted scene of the embodiment of the present invention is usually that corresponding neighboring community is
The scene of multiple (being more than or equal to 2), the embodiment of the present invention do not repeat this.
Step 202: the signal level for each neighboring community that will acquire is ranked up according to the height of signal level.
Specifically, can sequence according to the sequence of signal level from low to high or from high to low it is each adjacent small to what is got
The signal level in area is ranked up, and the signal level after being sorted, the embodiment of the present invention does not repeat this.
Further, it is assumed that each neighboring community (Cell1 for itself place main serving cell (Cell0) that terminal receives
~Cell6) signal level it is as shown in table 1, then in this step 202, if according to the sequence of signal level from low to high to obtaining
The signal level of each neighboring community (Cell1~Cell6) got is ranked up, then the signal level after obtained sequence can
To indicate are as follows:
-84dBm、-83dBm、-82dBm、-81dBm、-80dBm、-79dBm。
Step 203: minimum signal level is chosen from the signal level after sequence as initial signal level to be compared.
Specifically, it will again be assumed that each neighboring community (Cell1 for itself place main serving cell (Cell0) that terminal receives
~Cell6) signal level it is as shown in table 1, then in this step 203, selected initial signal level to be compared can for-
84dBm (signal level of adjacent area Cell6).
Step 204: judging the absolute of the difference of the signal level to be compared chosen and secondary low-signal levels adjacent thereto
Whether value is less than predetermined threshold value, if it is not, 205 are thened follow the steps, if so, thening follow the steps 206.
Wherein, the reception error that is generated when the predetermined threshold value can be according to the terminal received signals level and it is pre-
First it is arranged.For example, if the reception error that generates of when terminal received signals level is 1dB, the predetermined threshold value
Value range can be (0,10dB), i.e., the described predetermined threshold value concretely 3dB, 5dB or 6dB etc..More preferably, in order to not
While the accuracy of interfered cell determined by reducing, the complexity of information processing is reduced, the predetermined threshold value can be set
It is set to relatively high numerical value, such as can set (5,10dB), the embodiment of the present invention for the value range of the predetermined threshold value
This is not limited in any way.
Specifically, in this step 204, it is assumed that itself main clothes in place that the predetermined threshold value is 6dB, terminal receives
Be engaged in cell (Cell0) each neighboring community (Cell1~Cell6) signal level it is as shown in table 1, and assume it is selected to than
Be -84dBm compared with signal level, then can determine selected signal level to be compared and secondary low-signal levels adjacent thereto (-
The absolute value (1dB) of difference 83dBm) is less than predetermined threshold value.
Step 205: giving up selected signal level to be compared, and judge adjacent with selected signal level to be compared
Secondary low-signal levels whether be the highest signal level of level, if it is not, 207 are thened follow the steps, if so, going to step
209。
Step 206: retaining selected signal level to be compared, and judge adjacent with selected signal level to be compared
Secondary low-signal levels whether be the highest signal level of level, if it is not, 208 are thened follow the steps, if so, going to step
209。
For example, it is assumed that itself place main serving cell that the predetermined threshold value is 6dB, terminal measurement receives
(Cell0) signal level of each neighboring community (Cell1~Cell6) is as shown in table 1, and assumes selected signal to be compared
Level is -84dBm, then in this step 206, can retain selected signal level (- 84dBm) to be compared.Also, due to
The adjacent secondary low-signal levels (- 83dBm) of selected signal level (- 84dBm) to be compared are not the highest signal of level
Level, thus, the operation of step 208 can be continued to execute.
Step 207: using the secondary low-signal levels adjacent with selected signal level to be compared as new letter to be compared
Number level, and go to step 204.
Step 208: by the sum of selected signal level to be compared and secondary low-signal levels adjacent thereto as new
Signal level to be compared, and go to step 204.
For example, it is assumed that itself place main serving cell (Cell0) that the predetermined threshold value is 6dB, terminal receives
The signal level of each neighboring community (Cell1~Cell6) is as shown in table 1, and assume selected signal level to be compared be-
84dBm can be by selected signal level (- 84dBm) to be compared and secondary low signal adjacent thereto then in this step 208
The sum of level (- 83dBm) continues to execute the operation of step 204 as new signal level to be compared.
Step 209: terminating this operation, and using neighboring community corresponding to the signal level finally retained as described in
The interference adjacent area of main serving cell.
Further, it should be noted that by least one is adjacent small corresponding to the signal level finally retained
After area is as the interference adjacent area of the main serving cell, the method may also include that
The main service is determined according to the signal level of the signal level of the interference adjacent area and the main serving cell
The signal-to-noise ratio of cell.Due at this point, identified interference adjacent area is more accurate compared with the prior art, so that according to determining
The signal-to-noise ratio of main serving cell that is calculated of signal level of interference adjacent area more meet reality, accuracy is higher.
Further, below by each neighboring community of itself the place main serving cell (Cell0) received with terminal
For the signal level of (Cell1~Cell6) is as shown in table 1, and the predetermined threshold value is 6dB, to institute of the embodiment of the present invention

Come) value, obtain 23.244*10-9Then mw is scaled -76.336dBm again, that is, can determine new letter to be compared
Number level is -76.336dBm.
Later, can calculate | (- 76.336dBm)-(- 80dBm) | value, obtain 3.664dB.Due to 3.664dB < 6dB, because
This, at this point, the new signal level (- 76.336dBm) to be compared need to be retained, and can by the new signal level to be compared (-
76.336dBm) and the sum of secondary low-signal levels (- 80dBm) adjacent thereto are as signal level to be compared newly.That is, can incite somebody to action
The sum of (- 84dBm), (- 83dBm), (- 82dBm), (- 81dBm) and (- 80dBm) is as new signal level to be compared.

80dBm conversion) value, obtain 3.324*10-8Then mw is scaled -74.782dBm again, that is, can determine new
Signal level to be compared be -74.782dBm.
Later, can calculate | (- 74.782dBm)-(- 79dBm) | value, obtain 4.218dB.Due to 4.218dB < 6dB, because
This, at this point, the new signal level (- 74.782dBm) to be compared need to be retained, also, due at this point, with the letter to be compared newly
