101 :Base station obtains the interference measurements for the different system interference that terminal is subject to, the interference that the other systems outside current access system that wherein different system interference sign terminal is subject to are caused, interference volume is characterizes the physical quantity of different system interference intensity, and interference measurements include the current service sector of terminal and the interference measurements of adjacent sectors；The communication system of different systems can produce different system interference, such as global system for mobile communications when reusing frequency spectrum resource（Global System for Mobile Communications, GSM), WCDMA（Wideband Code-Division Multiple Access, WCDMA), time division SCDMA (Time-Division Synchronous Code-Division Multiple Access, TD-SCDMA), worldwide interoperability for microwave accesses（Worldwide Interoperability for Microwave Access, WiMax), Long Term Evolution（Long Term Evolution, LTE) etc., two or more coexistence of communication systems and when reusing frequency spectrum, then different system each other, such as in gsm system and LTE system, GSM systems are different system for LTE system, and LTE system is different system for gsm system.Interference volume, to characterize the physical quantity of different system interference intensity, is specifically that can refer to such as the received signal code power in WCDMA system（Received Signal Code Power, RSCP), received signal strength indicator（Received Signal Strength Indication, RSSI) etc., or such as the Reference Signal Received Power in LTE system（Reference Signal Receiving Power, RSRP), Reference Signal Received Quality (Reference Signal Received Quality, RSRQ) etc..

The method that base station obtains the interference measurements of different system interference that terminal is subject to can be：Base station sends the instruction of the first interferometry to the terminal for needing to evade different system interference, it is desirable to which the interference volume of terminal-pair current access system is measured.Terminal is received after the first interferometry instruction of base station transmission, can immediately or at regular intervals after, start measurement, obtain the interference measurements of current service sector and adjacent sectors.Terminal is completed after measurement, and by measurement result reporting base station, base station can obtain the interference measurements of terminal.The method that base station obtains the interference measurements of different system interference that terminal is subject to can also be：If the current service sector and adjacent sectors of terminal provide service for same base station, the interference volume of current service sector and adjacent sectors belonging to the direct measurement terminal of base station, for example, what base station was covered small divides into 3 sectors, that is sector 0, sector 1 and sector 2,120 degree of scope is covered each by per sector, the terminal current moon, good business sector was sector 0, and adjacent sectors are sector 1 and sector 2.Base station can obtain the interference measurements on this 3 sectors with direct measurement.The method that base station obtains the interference measurements of different system interference that terminal is subject to can also be：Base station can obtain interference measurements by the way of being combined by terminal measurement report and base station direct measurement.Such as the interference volume of the current service sector of base station direct measurement terminal, other base station also sends the instruction of the second interferometry to terminal, it is required that being reported after the interference volume of terminal measurement adjacent sectors, the current service sector of terminal and the interference measurements of adjacent sectors can be obtained using the method base station.

MSIn difference is δ MSI1, δ MSI2... ... δ MSIn, and δ MSI1, δ MSI2... ... δ MSIn and threshold value are compared；To S MSIi, (l i n, i are positive integer）It is compared with threshold value, if 5 MSK are less than, threshold value is invalid, i-th adjacent sectors of judgement are not the interference sector of the terminal；If 5 MSK are set up less than threshold value, the interference sector that i-th of adjacent sectors is the terminal is adjudicated；

103:Court verdict of the base station according to interference sector, is that terminal distribution can avoid the transfer resource of different system interference, wherein can avoid the transfer resource of different system interference includes：Base station can be subtracted different system on current service sector and interference sector using the transfer resource in frequency range by the transfer resource of terminal distribution.

Base station is that the method that terminal carries out resource allocation can be：Different system in terminal current service sector uses frequency range fO, and different system interference can be caused to terminal, To avoid this interference, base station can not be the transfer resource at f0 frequency ranges in terminal distribution current system；Terminal adjacent sectors, sector 1 is that the different system in interference sector, sector 1 uses frequency range fl, and different system interference can be caused to terminal, and to avoid this interference, base station can not be the transfer resource at fl frequency ranges in terminal distribution current system；Terminal adjacent sectors, sector 2 is not interference sector, and different system uses frequency range in sector 2, and the interference caused to terminal can be ignored, and base station can be the transfer resource at terminal distribution current system Mid Frequency.

301 :Base station sends the instruction of the first interferometry to terminal, it is desirable to which terminal-pair RSCP is measured；The instruction of first interferometry can be but not limit RRC measurement instructions, base station sends RRC measurement instructions to terminal, optionally, the present embodiment designated terminal in RRC measurement instructions is measured using RSCP as interference volume, but can specify other physical quantitys as interference volume during implementing.RSCP is the physical quantity that WCDMA carries out channel quality assessment, terminal accesses WCDMA system, signal intensity that can not be directly to terminal current service sector and the GSM systems of adjacent sectors is measured, in order to assess the different system interference that GSM signals are caused to terminal, the RSCP of WCDMA system can be measured as the physical quantity for assessing GSM signal intensities.

302:Terminal receives the first interferometry instruction of base station transmission, and RSCP is measured, measurement result is obtained；

Terminal receives the first interferometry instruction of base station transmission, and starts to measure the RSCP of WCDMA system in sector 0, sector 1 and sector 2.The RSCP of terminal measurement sector 0, sector 1 and sector 2, obtains sector 0, sector 1 and sector

2 interference volume can be designated as RSCP0, RSCP1 and RSCP2 respectively.

303:Terminal reports interference measurements to base station；Terminal is completed after measurement, can be at once or according to the setting of system, measurements RSCP0, RSCP1 and RSCP2 will be disturbed at the T moment, by but be not limited to RRC measurement report messages and report base station, so as to which base station obtains interference measurements, wherein, in the present embodiment using can using but be not limited to the T moment of systematic parameter as the time of terminal report measurement results, numerical value can with but do not limit the index requests such as time delay, synchronization reasonably set according to system.

It is the band downlink in gsm system and WCDMA system, base station directly can not be measured to interference volume according to the scene setting of the present embodiment, thus base station obtains and disturbs the method for measurements can be with For by terminal measure and on.In addition, during implementing, when the scene of GSM systems and WCDMA system reuse frequency spectrum is two system reuse uplink band, the method that base station obtains interference measurements can directly measure for base station to interference volume.

304:Base station calculates RSCP0 and subtracts RSCP1 and RSCP2 difference for δ RSCP1 and 6 RSCP2 respectively, and 5 RSCP1 and δ RSCP1 are compared with threshold value, and judgement obtains interference sector；

Base station is obtained after interference measurements RSCP0, RSCP1 and RSCP2, and δ RSCP1 and δ RSCP2 can be designated as by RSCP0 is calculated respectively subtracting RSCP1 and RSCP2 difference.TH can be represented using symbol as threshold value using can use but not limit systematic parameter in the present embodiment, numerical value can with but do not limit the indexs such as the robustness disturbed according to system counter and reasonably set.

δ RSCP1 and threshold value Τ Η are compared, δ RSCP1 are obtained to set up less than Τ Η, illustrate suitable with the WCDMA signal intensities from sector 1 from sector 0, it will thus be seen that intersection of the terminal in sector 0 and sector 1, therefore judgement adjacent sectors 1 are the sector that different system interference is caused to terminal；

δ RSCP2 and threshold value Τ Η are compared, obtain δ RSCP2 invalid less than Τ Η, illustrate that the WCDMA signal intensities from sector 2 are much smaller than the WCDMA signals from sector 0, show that the different system interference that terminal is caused by the GSM signals from sector 2 is limited, it can ignore, sector 2 is not the sector that different system interference is caused to terminal.

Court verdict is：The different system interference that GSM signals from sector 1 cause can not ignore to the WCDMA signals of terminal, thus sector 1 is interference sector；GSM signals from sector 2 cause different system interference to ignore the WCDMA signals of terminal, and sector 2 is non-interference sector.

305:Court verdict of the base station according to interference sector, is that terminal distribution can avoid the transfer resource of different system interference.

GSM signals from sector 0 and sector 1 can be interfered to the WCDMA signals of terminal, need to avoid the transfer resource on the frequency spectrum that is used on this 3 sectors using gsm system when base station carries out resource allocation, as shown in Figure 3 d, concrete operation method is frequency spectrum usage mode：Frequency range in WCDMA system available for data transfer is 1940 ~ 1945MHz, because being disturbed by from GSM signals, need to avoid the frequency range that gsm system is used on sector 0 and sector 1, respectively 1940 ~ 1941MHz and 1942 ~ 1943MHz, the frequency range that GSM systems are used on sector 2 need not be avoided, is 1944-1945MHz, thus determine that terminal can carry out data transmission on frequency range 1941 ~ 1942MHz and 1943 ~ 1945MHz, the transfer resource that base station should be distributed in this frequency range is used for the downlink data transmission of the WCDMA systems of terminal.

In the present embodiment, WCDMA system extreme positions may be disturbed by the GSM signals from current service sector and 2 adjacent sectors, interference of the GSM signals of base station judgement sector 2 to terminal can be ignored, terminal can use gsm system and the reuse frequency spectrum of WCDMA system on sector 2 to carry out data transmission, without evading.Compare and the transfer resource in all reuse frequency ranges is avoided in the prior art, the scheme that the present embodiment is provided effectively raises the accuracy that different system interference is evaded when transfer resource is carried out on frequency spectrum is reused, and then lifts frequency language service efficiency.
