As LTE (Long Term Evolution, Long Term Evolution) technology develops rapidly, GSM (Global System For Mobile, global system for mobile communications) business can gradual atrophy, can be increasingly in the market share that following GSM is occupied It is few, especially in world developed area.

In order to comply with above-mentioned development trend, while GSM frequency spectrums are utilized in maximum efficiency, industry proposes the general of frequency spectrum share Read, i.e., when gsm service demand is smaller, vacate a part of GSM frequency spectrums to LTE network, or UMTS (Universal MobileTelecommunication System, UMTS) network user use.With GSM network and LTE Exemplified by network spectrum shares (abbreviation GL frequency spectrum shares), common GL frequency spectrum shares need just to have planned GO when arranging net (GSM Only) region, GL frequency spectrum shares region and GL shared buffers region (Buffer Zone), wherein each region is to original The service condition of GSM frequency spectrums is as follows：

1) for GO regions, GSM cell in the region can be with whole GSM frequencies that normal use operator possesses Spectrum；

2) for GL frequency spectrum shares region, whole GSM frequency spectrums that operator possesses are divided into continuous two parts, and one Part is that the GSM cell that basic frequency spectrum is reserved in the region uses, and another part is shared frequency spectrum, is sold in the region LTE cells use；

3) for GL shared buffers region, the GSM cell in the region can only use to be protected in GL frequency spectrum shares region Leaving the width of the GSM portions of the spectrum that GSM cell uses and buffer area for spatially needs to reach 3~5 station spacings, so as to Ensure the performance of the LTE cells in GL frequency spectrum shares region.

In a kind of existing frequency spectrum share scene, GSM frequency spectrums, which sell flow, can specifically include：

1) BSC (Base Station Controller, base station controller) from network management entity obtain buffer area and GL frequency spectrum shares region；

2) BSC detects the GSM cell traffic total amount in buffer area and GL frequency spectrum shares region；

If 3) the GSM cell traffic total amount in buffer area and GL frequency spectrum shares region is less than thresholding, BSC is then slow by closing The part GSM carrier frequency for rushing region and GL frequency spectrum shares region vacates frequency spectrum to be shared；

4) BSC notifies network management entity GSM to share frequency spectrum；

5) LTE cells in network management entity activation GL frequency spectrum shares region, and complete supporting S1 interfaces and X2 interface and match somebody with somebody Put；If LTE bases frequency spectrum in GL frequency spectrum shares region be present, network management entity can also notify LTE to be used by CA modes Shared frequency spectrum.

GSM frequency spectrums recovery stream can specifically include：

1) under in GSM, warp-wise LTE shares frequency spectrum state, the GSM in BSC monitoring buffer areas and GL frequency spectrum shares region Cell telephone traffic total amount；

2) if the traffic total amount of buffer area and GL frequency spectrum shares region GSM cell meets that frequency spectrum reclaims condition, BSC then leads to Know that network management entity carries out frequency spectrum recovery；

3) network management entity deactivates LTE cells, and deactivates supporting S1 interfaces and X2 interface.

The above-mentioned problems of the prior art is that buffer area can not use shared bandwidth resources, reduce wireless network The utilization rate of frequency spectrum, currently existing scheme meet situation with the GSM cell traffic total amount in buffer area and GL frequency spectrum shares region To decide whether to reclaim the shared frequency spectrum in GL frequency spectrum shares region.However, the recovery action be related to buffer area and All GSM cell and LTE cells in GL frequency spectrum shares region, flexibility is short of, and when existing scheme is for GL frequency spectrum shares Some GSM cells in buffer area traffic congestion occur but the GSM cell traffic in buffer area and GL frequency spectrum shares region Total amount do not trigger frequency spectrum recovery condition when, network will not active accommodation these there is the GSM cell of traffic congestion so that The communication conditions of localized network cannot slowly improve and then influence Consumer's Experience.
