Embodiment

The scheme of the embodiment of the present invention is by determining the Broadcast Control Channel (BCCH of the Serving cell resident with terminal, Broadcast Control Channel) the identical and Base transceiver Station Identity Code (BSIC of frequency, Base transceiver Station Identity Code) different specific cells, determine the co-channel interference source of base station according to the BCCH frequency of specific cell and BSIC, can determine accurately and rapidly the co-channel interference source of base station.

Below in conjunction with Figure of description, embodiments of the present invention is further illustrated, but the present invention is not limited to the following examples.

Embodiment mono-:

As shown in Figure 1, in the embodiment of the present invention one, the method in definite co-channel interference source comprises the following steps:

Step 101: base station sends the BCCH frequency of the resident Serving cell of this terminal to terminal;

Step 102: the co-channel interference source of this base station is determined in base station according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report, or base station notifies the BSIC of the specific cell of the BCCH frequency of Serving cell and described terminal to report to the Centralized Controller being connected with this base station.

Wherein, specific cell be identical from the BCCH frequency of Serving cell and with the BSIC of Serving cell different community.

Wherein, the cell parameter information such as the BCCH frequency of the community of base station and BSIC can be by the unified configuration of the Centralized Controller being connected with this base station.Particularly, base station can send the cell ID (CI that comprises above-mentioned Serving cell to Centralized Controller, Cell Identity) cell parameter configuring request, Centralized Controller is receiving after the cell parameter configuring request of this base station transmission, can be this Serving cell configuration BCCH frequency and BSIC, and store the corresponding relation of BCCH frequency, BSIC and the cell ID of this Serving cell.Base station is receiving after the BCCH frequency and BSIC that Centralized Controller is this Serving cell configuration, and BCCH frequency and the BSIC of this Serving cell can be set.

It should be noted that, the Centralized Controller in embodiment of the present invention scheme can connect multiple base stations, and is cell allocation BCCH frequency and the BSIC of base station, is illustrated in figure 2 the schematic diagram that Centralized Controller is connected with multiple base stations (as 1～base station, base station 6).Wherein, have stronger interference for fear of the minizone of same base station, Centralized Controller is that the BCCH frequency of multiple cell allocation of a base station is all not identical.But, because frequency resource is limited, Centralized Controller is that the BCCH frequency of the cell allocation of two base stations may be identical, but for Liang Ge community, two base stations, the BCCH frequency of above-mentioned two cell allocation is identical if, be the BSIC difference of above-mentioned two cell allocation, ensure that Centralized Controller is that BCCH frequency and the BSIC of cell configuration of base station is unique.Centralized Controller, after being the cell configuration BCCH frequency and BSIC of base station, can be stored the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of this base station.Alternatively, Centralized Controller can be handed down to each base station by the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of the each base station being connected with self.

It should be noted that, if BCCH frequency and the BSIC of the community of the base station being connected with Centralized Controller upgrade, this base station need be notified to Centralized Controller upgrading BCCH frequency and the BSIC of Hou community, is up-to-date with the corresponding relation of the BCCH frequency, BSIC and the cell ID that ensure to store in Centralized Controller.If Centralized Controller detects the base station being connected with self and disconnects, the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of this base station is deleted.

Alternatively, base station is before sending cell parameter configuring request to Centralized Controller, can first intercept BCCH frequency and BSIC that the community of adjacent base station is used, and the BCCH frequency that the community of the adjacent base station listening to is used and BSIC notify to Centralized Controller, the cell allocation BCCH frequency that is this base station as Centralized Controller and the reference information of BSIC.For example, after BCCH frequency and BSIC that Centralized Controller uses in the community that receives the adjacent base station that base station listens to, can be the BCCH frequency that the cell allocation of this base station is different with the community of the adjacent base station listening to, disturb to reduce adjacent area.

Alternatively, base station can inform the geographical location information of self to Centralized Controller by cell parameter configuring request, and Centralized Controller can be determined the particular location of the base station at the place, community that cell ID is corresponding.Wherein, the geographical location information of base station can acquire by the global positioning system (GPS, Global Positioning System) being arranged in base station.

Alternatively, base station can be under the control of Centralized Controller and intervening, the BCCH frequency of complete independently community and the configuration of BSIC, its specific implementation can be: base station is determining and need to, for the cell configuration BCCH frequency of self with when BSIC, send the cell parameter configuring request of the cell ID that comprises this community to Centralized Controller; Centralized Controller is receiving after the cell parameter configuring request of this base station transmission, and the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of each base station that self is stored is handed down to this base station; This base station, receiving after the corresponding relation of BCCH frequency, BSIC and cell ID that Centralized Controller issues, is this cell configuration BCCH frequency and BSIC, and wherein, BCCH frequency and BSIC that base station is cell configuration are unique.Afterwards, base station can report Centralized Controller by the corresponding relation of BCCH frequency, BSIC and cell ID of the community that has configured BCCH frequency and BSIC.

In step 101, the i.e. community of this terminal access, Serving cell that terminal is resident.Base station arranges after BCCH frequency and BSIC in this Serving cell that is configured to according to Centralized Controller, the BCCH frequency of this Serving cell can be sent to the terminal that resides in this Serving cell.Particularly, base station can be notified the BCCH frequency of Serving cell to terminal by a special signaling, determines the community identical with the BCCH frequency of this Serving cell with indicating terminal.Terminal, receiving after the BCCH frequency of this Serving cell, can be determined the community identical with the BCCH frequency of this Serving cell.

If the identical community of terminal BCCH frequency that determine and Serving cell is specific cell, be that the BSIC of community that terminal BCCH frequency that determine and Serving cell is identical is different with the BSIC of Serving cell, represent the current adjacent cell use BCCH frequency identical with Serving cell that have, and the signal strength signal intensity of this adjacent cell is greater than the signal strength signal intensity of Serving cell, this specific cell of determining is the adjacent cell identical with the BCCH frequency of Serving cell, namely the co-channel interference source of base station.This is because for a BCCH frequency, terminal only can detect the signal strength signal intensity Qiang community that uses this BCCH frequency.

If the Bu Shi specific cell, community that terminal BCCH frequency that determine and Serving cell is identical, be that the BSIC of community that terminal BCCH frequency that determine and Serving cell is identical is identical with the BSIC of Serving cell, represent the current adjacent cell use BCCH frequency identical with Serving cell that do not have, even if or have adjacent cell to use the BCCH frequency identical with Serving cell, the signal strength signal intensity of this adjacent cell is less than the signal strength signal intensity of Serving cell, and this adjacent cell is less to the interference of Serving cell.

In order to find out the adjacent cell identical with the BCCH frequency of Serving cell (being co-channel interference source) efficiently, base station can send to the terminal at the edge in Serving cell the BCCH frequency of this Serving cell.This is because the terminal searching at the edge in Serving cell is larger to the possibility of the adjacent cell identical with the BCCH frequency of Serving cell.

Particularly, base station can be selected the terminal at the edge in above-mentioned Serving cell in the following manner:

Mode one: the terminal of selecting newly to switch to this Serving cell.

Mode two: select descending incoming level value to be less than the terminal of first threshold.

Wherein, descending incoming level value be less than downstream signal that base station that first threshold represents that terminal receives sends a little less than, terminal is subject to adjacent cell serious interference, the edge of terminal in Serving cell.

Mode three: select uplink receiving level value to be less than the terminal of Second Threshold.

Wherein, uplink receiving level value is less than Second Threshold, and a little less than representing that upward signal that the terminal that receives of base station sends, terminal is subject to adjacent cell serious interference, the edge of terminal in Serving cell.

Mode four: select descending incoming level value to be greater than the terminal that the 3rd threshold value and descending quality of reception value are greater than the 4th threshold value.

Wherein, descending incoming level value is greater than the 3rd threshold value and descending quality of reception value is greater than the 4th threshold value, and the effect of the downstream signal that expression terminal reception base station sends is poor, and terminal is subject to adjacent cell serious interference, the edge of terminal in Serving cell.

Mode five: select uplink receiving level value to be greater than the terminal that the 5th threshold value and uplink receiving mass value are greater than the 6th threshold value.

Wherein, uplink receiving level value is greater than the 5th threshold value and uplink receiving mass value is greater than the 6th threshold value, and the effect of the upward signal that expression base station receiving terminal sends is poor, and terminal is subject to adjacent cell serious interference, the edge of terminal in Serving cell.

Mode six: the interference level value of selecting up idle frame to record is greater than the terminal of the 7th threshold value.

Because terminal can not send data at idle frame, therefore, the signal that base station receives at idle frame is interference signal, and the received signal level value recording at idle frame is interference level value.The interference level value that base station records at idle frame is greater than the 7th threshold value and represents that base station is subject to adjacent cell serious interference, and according to the processing of uplink downlink approximately equal principle, terminal is subject to adjacent cell serious interference, the edge of terminal in Serving cell.

Particularly, above-mentioned terminal can be the mobile terminal that carries out circuit switching (CS, Circuit Switched) business (as speech business).Wherein, above-mentioned descending incoming level value and descending quality of reception value can obtain from the measurement report of terminal to report, and uplink receiving level value and uplink receiving mass value can obtain from the measurement report of base station.

Wherein, incoming level value is specially the value of received signal level (RXLEV, Received Signal Quality), reflection be the power of the signal that receives.Incoming level value is larger, represents that the power of the signal receiving is larger.Quality of reception value is specially the grade point of received signal quality (RXQUAL, Received Signal Quality).Quality of reception value is larger, and the error rate is higher, represents that signal quality is poorer.For example, when RXQUAL=3, the error rate is 0.8%～1.6%; When RXQUAL=4, the error rate is 1.6%～3.2%.

Above-mentioned first threshold～seven threshold value all can be set according to actual conditions, for example, can determine according to demodulation ability, the residing wireless environment etc. of hardware.In a specific embodiment, can set first threshold for-95dBm, Second Threshold for-90dBm, the 3rd threshold value for-75dBm, the 4th threshold value be that 5(is that the error rate is 3.2%～6.4%), the 5th threshold value for-70dBm, the 6th threshold value are 5, the 7th threshold value is-90dBm.

It should be noted that,, in the time selecting in the manner described above the terminal at the edge in above-mentioned Serving cell, can adjudicate by the measurement report based on instantaneous base station, also can adjudicate by the measurement report based in Preset Time section.For example, in mode two as example, can select current descending incoming level value to be less than the terminal of first threshold, also can be chosen in the terminal that the interior descending incoming level value of Preset Time section is all less than first threshold, the mean value that also can be chosen in descending incoming level value in Preset Time section is less than the terminal of first threshold, and the scheme of the embodiment of the present invention does not limit this.

Alternatively, the terminal at the edge in Serving cell also can be selected according to the covering radius of the distance between terminal and base station and the resident Serving cell of terminal in base station.For example, can select distance between base station to be greater than a predeterminable range threshold value and be less than the terminal of the covering radius of Serving cell.

Base station is being selected after terminal, can send by special signaling the BCCH frequency of Serving cell to terminal, determines the community identical with the BCCH frequency of this Serving cell with indicating terminal.

The terminal that receives the BCCH frequency of the Serving cell that base station issues is being determined behind the community identical with the BCCH frequency of Serving cell, can directly the BSIC of the community of determining be reported to base station, and not judge that whether the BSIC of the community of determining is different from the BSIC of Serving cell; The BSIC of the community that also can determine in definite this terminal be that the BSIC(BSIC of community that definite this terminal is determined of specific cell is different with the BSIC of Serving cell) after, the BSIC of the community of determining is reported to base station, if the BSIC of the community that terminal is determined is not the BSIC of specific cell, do not report the BSIC of the community of determining.Wherein, the community that terminal is determined is the identical community of terminal BCCH frequency that determine and Serving cell.

Based on this, if terminal is being determined behind the community identical with the BCCH frequency of Serving cell, directly the BSIC of the community of determining is reported to base station, base station is receiving after the BSIC of terminal to report, whether the BSIC that needs the community of determining that judge terminal to report is that the BSIC(of specific cell judges that whether the BSIC of terminal to report is different from the BSIC of Serving cell), if so, perform step 102; Otherwise, determine the co-channel interference source of not finding base station, can return to step 101.

If terminal is only after the BSIC that determines the community that this terminal is determined is the BSIC of specific cell, just report the BSIC of the community of determining, base station is receiving after the BSIC of the community of determining of terminal to report, directly execution step 102, if the BSIC of the community of determining of terminal to report is not received in base station in Preset Time section, determine the co-channel interference source of not finding base station, can return to step 101.

Alternatively, no matter terminal is the BSIC that directly reports the community of determining, or terminal is the BSIC that just reports the community of determining after the BSIC of specific cell at the BSIC that determines the community determined of this terminal, base station is receiving after the BSIC of the community of determining of terminal to report, whether the BSIC that all judges the community of determining of terminal to report is the BSIC of specific cell, if so, perform step 102; Otherwise, determine the co-channel interference source of not finding base station, can return to step 101.

Alternatively, base station is being selected after terminal, can add the BCCH frequency of Serving cell resident terminal to BA2(BA:BCCH Allocation, BCCH distributes) send to terminal by slow associated control channel (SACCH, Slow Associated Control Channel) in table.

Terminal, receiving after the BA2 table that base station issues, can detect the community identical with the BCCH frequency of Serving cell, determines the community identical with the BCCH frequency of Serving cell.

It should be noted that, in BA2 table except the BCCH frequency that comprises Serving cell, also can comprise other BCCH frequencies, terminal is receiving after the BA2 table that base station issues, can detect the each BCCH frequency in BA2 table, and report BCCH frequency, BSIC and the incoming level value of the strongest Liu Ge of signal strength signal intensity community.Wherein, for a BCCH frequency, terminal only can detect the signal strength signal intensity Qiang community that uses this BCCH frequency.Therefore, in order to ensure that terminal can report BCCH frequency and the BSIC of the community identical with the BCCH frequency of Serving cell, in the BA2 table that base station issues to terminal, comprise at most 6 BCCH frequencies, and the BCCH frequency that comprises Serving cell in this BA2 table.

Particularly, terminal is being determined behind the community identical with the BCCH frequency of Serving cell, the position of the BCCH frequency of corresponding with service community in the BA2 table that can issue in base station, fill in the BSIC of the community that BCCH frequency that determine and Serving cell is identical, and the BA2 table after filling in is reported to base station by SACCH channel, the BCCH frequency of the community that terminal to report BCCH frequency that determine and Serving cell is identical and the corresponding relation of BSIC.Alternatively, the BSIC of the community that terminal is only determined in definite this terminal is that the BSIC(BSIC of community that definite this terminal is determined of specific cell is different with the BSIC of Serving cell) time, just report the BCCH frequency of the community of determining and the corresponding relation of BSIC.

Wherein, the BCCH frequency of terminal to report is specially absolute frequency point number (ARFCN, Absolute Radio Frequency Number).

Based on this, the BSIC of specific cell can, from the corresponding relation of the BCCH frequency of terminal to report and BSIC, be determined in base station.Particularly, the BSIC that the BCCH frequency identical with the BCCH frequency of Serving cell is corresponding can be searched in base station from the BA2 table of terminal to report, and whether the BSIC that judgement finds is different from the BSIC of Serving cell, if different, performs step 102; Otherwise, determine the co-channel interference source of not finding base station, can return to step 101.

If terminal is only after the BSIC that determines the community that this terminal is determined is the BSIC of specific cell, just report the BCCH frequency of the community of determining and the corresponding relation of BSIC, the BSIC that the BCCH frequency identical with the BCCH frequency of Serving cell is corresponding can be searched in base station from the BA2 table of terminal to report, if can find, perform step 102; Otherwise, determine the co-channel interference source of not finding base station, can return to step 101.

In step 102, the co-channel interference source that base station is determined according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report in base station, specifically comprises:

The cell ID corresponding to BSIC of the BCCH frequency of Serving cell and the specific cell of terminal to report, according to the corresponding relation of BCCH frequency, BSIC and cell ID, determined in base station, and determines the co-channel interference source of the Wei Gai base station, community that this cell ID is corresponding.The corresponding relation of BCCH frequency, BSIC and the cell ID of the community of the each base station wherein, being connected with Centralized Controller is handed down to each base station in advance by Centralized Controller.

Alternatively, the BSIC of the BCCH frequency of base station Ke Jiang Serving cell and the specific cell of terminal to report notifies to the Centralized Controller being connected with base station.Particularly, base station can send to Centralized Controller the Location Request of the BSIC of the specific cell of the BCCH frequency that comprises Serving cell and terminal to report.Centralized Controller is receiving after the Location Request of base station transmission, can determine according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report the co-channel interference source of base station.Particularly, Centralized Controller can be according to the corresponding relation of BCCH frequency, BSIC and cell ID, determine the cell ID corresponding to BSIC of the BCCH frequency of Serving cell and the specific cell of terminal to report, and determine the co-channel interference source that community corresponding to this cell ID is base station.

With two concrete examples, the scheme of the embodiment of the present invention is described below.

As shown in Figure 3, in embodiment of the present invention scheme, the concrete application flow of the method in definite co-channel interference source comprises the following steps:

Step 301: base station powers on, sends cell parameter configuring request to Centralized Controller.

Wherein, in cell parameter configuring request, comprise the cell ID of the Serving cell of base station, alternatively, in cell parameter configuring request, also comprise the geographical location information of base station.

Step 302: Serving cell configuration BCCH frequency and BSIC that Centralized Controller is this base station.

Particularly, Centralized Controller can send cell parameter configuration response to base station, and wherein, in cell parameter configuration response, comprising Centralized Controller is BCCH frequency and the BSIC of the Serving cell configuration of this base station.

After being the Serving cell configuration BCCH frequency and BSIC of base station, Centralized Controller is stored the corresponding relation of BCCH frequency, BSIC and the cell ID of the Serving cell of this base station.Alternatively, Centralized Controller can be stored the corresponding relation of the geographical location information of BCCH frequency, BSIC, cell ID and the base station of the Serving cell of this base station.

Step 303: base station arranges BCCH frequency and the BSIC of Serving cell according to the configuration of Centralized Controller.

Step 304: the terminal at the base station selected edge in Serving cell.

Step 305: the BCCH frequency of Serving cell is sent to the terminal of selecting by base station.

Step 306: terminal is determined the community identical with the BCCH frequency of Serving cell, reports the BSIC of the community of determining.

The BCCH frequency of the community of wherein, determining is identical with the BCCH frequency of Serving cell.

Step 307: base station judges whether the BSIC of the community of determining of terminal to report is the BSIC of specific cell, if so, goes to step 308; Otherwise, go to step 310.

Wherein, base station judges whether the BSIC of the community of determining of terminal to report is the BSIC of specific cell, namely base station judges that whether the BSIC of the community that the BCCH frequency of terminal to report is identical from the BCCH frequency of Serving cell is different with the BSIC of Serving cell, if different, represent that the community that terminal is determined is the adjacent cell identical with the BCCH frequency of Serving cell, the namely co-channel interference source of base station.

Step 308: base station notifies the BCCH frequency of Serving cell and the BSIC of terminal to report to Centralized Controller.

Step 309: Centralized Controller is determined the co-channel interference source of base station according to the BSIC of the BCCH frequency of Serving cell and terminal to report, flow process finishes.

Particularly, Centralized Controller, according to the corresponding relation of BCCH frequency, BSIC and cell ID, is determined the BCCH frequency of Serving cell and the cell ID corresponding to BSIC of terminal to report, and determines the co-channel interference source that community corresponding to this cell ID is base station.

Step 310: the co-channel interference source of not finding base station is determined in base station, returns to step 304.

Alternatively, in step 302, Centralized Controller can be handed down to each base station by the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of the each base station being connected with self.Based on this, in step 308, the co-channel interference source of base station can directly be determined in base station according to the BSIC of the BCCH frequency of Serving cell and terminal to report, and does not need the BCCH frequency of Serving cell and the BSIC of terminal to report to report Centralized Controller.

Alternatively, in step 306, before the BSIC of the community that terminal to report is determined, can first judge whether the BSIC of the community of determining is the BSIC of specific cell, if so, report the BSIC of the community of determining; If not, do not report the BSIC of the community of determining.Based on this, in step 307, base station can not judge whether the BSIC of the community of determining of terminal to report is the BSIC of specific cell, and directly perform step 308, if the BSIC of the community of determining of terminal to report is not received in base station in Preset Time section, determine the co-channel interference source of not finding base station, return to step 304.

Alternatively, even if terminal only reports and the BCCH frequency BSIC identical and the different community with the BSIC of Serving cell of Serving cell, base station also can further judge whether the BSIC of the community of determining of terminal to report is the BSIC of specific cell.

As shown in Figure 4, in embodiment of the present invention scheme, another concrete application flow of the method in definite co-channel interference source comprises the following steps:

Step 401: base station powers on, sends cell parameter configuring request to Centralized Controller.

Step 402: Serving cell configuration BCCH frequency and BSIC that Centralized Controller is this base station.

Particularly, Centralized Controller can send cell parameter configuration response to base station, and wherein, in cell parameter configuration response, comprising Centralized Controller is Serving cell configuration BCCH frequency and the BSIC of this base station.

Step 403: base station arranges BCCH frequency and the BSIC of Serving cell according to the configuration of Centralized Controller.

Step 404: the terminal at the base station selected edge in Serving cell.

Step 405: base station is configured to the BCCH frequency of Serving cell in BA2 table, is handed down to the terminal of selecting.

Step 406: terminal is determined the community identical with the BCCH frequency of Serving cell, reports the BCCH frequency of the community of determining and the corresponding relation of BSIC.

The BCCH frequency of the community of wherein, determining is identical with the BCCH frequency of Serving cell.Particularly, in the BA2 table that terminal can issue in base station, the position of the BCCH frequency of corresponding with service community, fills in the BSIC of the community that BCCH frequency that determine and Serving cell is identical, and the BA2 table after filling in is reported to base station.

Step 407: base station judges whether the BSIC of the community of determining of terminal to report is the BSIC of specific cell, if so, goes to step 408; Otherwise, go to step 410.

Particularly, the BSIC that the BCCH frequency identical with the BCCH frequency of Serving cell is corresponding can be searched in base station from the BA2 table of terminal to report, and whether the BSIC that judgement finds is different from the BSIC of Serving cell, if different, goes to step 408; If identical, go to step 410.

Step 408: the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report is reported Centralized Controller by base station.

Alternatively, the BCCH frequency of the specific cell of terminal to report and the corresponding relation of BSIC are reported Centralized Controller by base station.

Step 409: Centralized Controller is determined the co-channel interference source of base station according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report, flow process finishes.

Step 410: the co-channel interference source of not finding base station is determined in base station, returns to step 404.

Alternatively, in step 402, Centralized Controller can be handed down to each base station by the corresponding relation of BCCH frequency, BSIC and the cell ID of the community of the each base station being connected with self.Based on this, in step 408, the co-channel interference source of base station can directly be determined in base station according to the BSIC of the BCCH frequency of Serving cell and terminal to report, and does not need the BCCH frequency of Serving cell and the BSIC of terminal to report to report Centralized Controller.

Alternatively, in step 406, before the BCCH frequency of the community that terminal to report is determined and the corresponding relation of BSIC, can first judge whether the BSIC of the community of determining is the BSIC of specific cell, if so, report the BCCH frequency of the community of determining and the corresponding relation of BSIC; If not, do not report the BCCH frequency of the community of determining and the corresponding relation of BSIC.Based on this, in step 407, the BSIC that the BCCH frequency identical with the BCCH frequency of Serving cell is corresponding can be searched in base station from the BA2 table of terminal to report, if can find, goes to step 408; If search less than, go to step 410.

Alternatively, even if terminal only reports and the BCCH frequency BCCH frequency identical and the different community with the BSIC of Serving cell of Serving cell and the corresponding relation of BSIC, whether base station also can further judge that whether the BSIC of the community of determining of terminal to report is that the BSIC(of specific cell is that base station judges identical BSIC corresponding to BCCH frequency of BCCH frequency that find and Serving cell from the BA2 table of terminal to report, different from the BSIC of Serving cell).

As shown in Figure 5, in the embodiment of the present invention two, the method in definite co-channel interference source comprises the following steps:

Step 501: terminal receives the BCCH frequency of the resident Serving cell of this terminal that base station sends;

Step 502: terminal is determined the community identical with the BCCH frequency of this Serving cell, and the BSIC of the community of determining is reported to base station.

Wherein, base station is receiving after the BSIC of the community of determining of terminal to report, can determine according to the BSIC of the specific cell of the BCCH frequency terminal to report of Serving cell the co-channel interference source of base station; Or the BSIC of the specific cell of the BCCH frequency terminal to report of Serving cell is notified to the Centralized Controller being connected with this base station, afterwards, Centralized Controller can be determined according to the BSIC of the specific cell of the BCCH frequency terminal to report of Serving cell the co-channel interference source of base station.Specific cell be identical from the BCCH frequency of Serving cell and with the BSIC of Serving cell different community.

Alternatively, terminal is after determining the community identical with the BCCH frequency of Serving cell, before the BSIC of the community of determining is reported to base station, the BSIC that the BSIC that can first determine the community that terminal BCCH frequency that determine and Serving cell is identical is specific cell.

If terminal is only after the BSIC that determines the community that this terminal is determined is the BSIC of specific cell, just the BSIC of the community of determining is reported to base station, base station is receiving after the BSIC of the community of determining of terminal to report, directly determines the co-channel interference source of base station according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report; Or the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report is notified to the Centralized Controller being connected with this base station.If the BSIC of the community of determining of terminal to report is not received in base station in Preset Time section, determine the co-channel interference source of not finding base station.

Alternatively, no matter terminal is the BSIC that directly reports the community of determining, or terminal is the BSIC that just reports the community of determining after the BSIC of specific cell at the BSIC that determines the community determined of this terminal, base station is receiving after the BSIC of the community of determining of terminal to report, whether the BSIC that all judges the community of determining of terminal to report is the BSIC of specific cell, if it is the BSIC of specific cell that the BSIC of the community of determining of terminal to report is judged in base station, determine the co-channel interference source of base station according to the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report, or the BSIC of the specific cell of the BCCH frequency of Serving cell and terminal to report is notified to the Centralized Controller being connected with this base station.
