Technical field

 The current wireless spectrum resources are very tight. However, when using wireless services, there will still be tides. That is, taking a cell as an example, there is a high amount of traffic in a part of the day, so the spectrum utilization rate is high, and in another part. Time traffic is low, even 0, resulting in a large amount of spectrum idle.

 In order to make full use of the idle spectrum resources in a certain period of time, a dynamic spectrum sharing scheme is proposed. FIG. 1 is a schematic diagram of a method for dynamic spectrum sharing in the prior art. As shown in FIG. 1, the main work of the method is shown. The principle is: acquiring the traffic volume of each GSM cell, and recording the GSM cell with the traffic volume less than 0.2, and the time period of the traffic volume of the GSM cell being less than 0.2. Then, the intersection of the shared time periods between the GSM cells with the traffic less than 0.2 is taken, and the GSM cell is geographically displayed, and the obtained cells are connected together to form a slice. Finally, the intersection is obtained according to the shared time period and the maximum is obtained. The shared area is the shared area (area A in Figure 1).

 In addition, interference estimation is performed on each GSM cell in the shared area, that is, which shared spectrum of the base station cannot be used by GSM, UMTS, or LTE, and the cell under the base station is used as a BufferZone (as shown in FIG. 1). The area B), where the BufferZone is used to prevent the base stations or terminals in any two cells between the area A and the area C from interfering with each other to affect the service quality.

 2 is a flowchart of Embodiment 1 of a method for processing a shared cell according to the present invention. As shown in FIG. 2, the processing method of the shared cell provided by this implementation includes:

 Step 101: Monitor and acquire the traffic volume of each cell, and use the cell with the traffic volume less than the preset threshold as the shared cell.

 Specifically, the operation support system (OSS) monitors the traffic situation of each cell in the coverage of the base station by using the base station controller, and acquires the traffic volume of each cell. When the traffic volume of the cell is less than the advance When the threshold is set, the above cell is used as a shared cell. In addition, the threshold value in the embodiment of the present invention is an empirical value, which can be set according to actual conditions, and no limitation is imposed herein.

 Step 102: If the spectrum of the corresponding interfering cell of the shared cell has been released, the idle spectrum of the shared cell is shared to UMTS or LTE.

Specifically, the so-called shared cell is that the spectrum in the shared cell is idle. At this time, after the spectrum of the corresponding interfering cell of the shared cell has been released, and in other communication systems, such as UTMS or When the LTE task is busy, the shared cell can release its idle spectrum for use by other communication systems with busy services to ensure the service quality of other communication systems.

 In an actual application, at least one interfering cell with no spectrum released may exist in the interfering cell corresponding to the shared cell. If the idle spectrum of the shared cell is shared with the UTMS or the LTE, communication interference may occur, and therefore, the sharing must be guaranteed. The spectrum of all the interfering cells corresponding to the cell has been released, and the idle spectrum of the shared cell can be shared to the UTMS or LTE.

 The processing method of the shared cell provided by the embodiment of the present invention obtains the traffic volume of each cell by real-time monitoring, compares the traffic volume of each cell with a preset threshold, and compares the traffic volume with the preset traffic amount. The cell with the threshold is used as the shared cell.

 Specifically, when the shared cell shares its own idle spectrum to the UMTS or the LTE, the hopping sequence MA of the spectrum is first adjusted to determine the shared frequency of the shared cell, that is, which spectrums in the shared cell are idle and can be shared. For UMTS or LTE, to ensure the quality of communication services.

 Preferably, the method may further include:

 Step 103: The interfering cell of the shared cell is used as a buffer cell of the shared cell.

 In this embodiment, when a cell is a shared cell, and the spectrum of the corresponding interfering cell of the shared cell is released, the interfering cell corresponding to the shared cell is used as a buffer cell of the shared cell, where The spectrum in the cell is not available to any communication network to ensure the quality of service between the shared cell and the base station or terminal in other cells than the shared cell and the interfering cell.

In addition, when the traffic volume of the buffered cell is less than the preset threshold, and the spectrum of the interfering cell corresponding to the buffered cell is released, the buffered cell is used as the shared cell. It should be noted that when If the traffic of the buffered cell is less than the preset threshold, and the spectrum of at least one of the interfering cells corresponding to the buffered cell is not released, the buffered cell may release its own idle spectrum, but the idle spectrum Cannot be shared for use by other network communication systems, ie UTMS or LTE cannot use the free spectrum released by the above buffered cells.

 Step 202: Calculate, according to the measurement result of each cell, an interference cell corresponding to each cell, and store each cell and an interference cell corresponding to each cell in a database.

 In an actual application, the OSS separately sends an instruction for measuring the traffic condition of the cell to each cell. Taking a cell as an example, the base station in the cell obtains each user equipment in the cell according to the measurement of the traffic condition of the cell. Equipment, referred to as UE, receives the signal strength of the neighboring cell, and obtains the maximum signal strength from the signal strength of the neighboring cell received by each UE, and carries the maximum signal strength in the reported measurement result. Further, OSS The base station transmit power in the neighboring cell of the cell, the transmit power of each user equipment in the cell, and the interference level threshold of each user equipment in the cell and the base station in the neighboring cell of the cell and the maximum signal Intensity, performing interference estimation on the cell, and acquiring an interference matrix corresponding to the cell, where the interference matrix includes an interference cell corresponding to the cell.

 In addition, the OSS may acquire the cells in the coverage of each base station and the interfering cells corresponding to each cell, and store each cell and the interfering cell corresponding to each cell in a certain format to the database. The above database may be set in the OSS. Inside.

 Step 203: Monitor and acquire the traffic volume of each cell, and use the cell with the traffic volume less than the preset threshold as the shared cell.

 Step 204: If the spectrum of the interfering cell corresponding to the shared cell has been released, share the idle spectrum of the shared cell to UMTS or LTE.

 In this embodiment, the query database can obtain the interfering cell of the shared cell, and then determine whether the spectrum of the interfering cell corresponding to the shared cell has been released.

The processing method of the shared cell provided by the embodiment of the present invention, by sending a measurement request, and reporting the measurement result by each cell, and measuring the measurement result of each cell and the interference cell corresponding to each cell The storage is stored in the database according to a certain storage format. Therefore, when monitoring the traffic volume of each cell to determine the shared cell, the interfering cell of the shared cell can be obtained by querying the database, and the spectrum of the interfering cell corresponding to the shared cell is determined to be released. When the idle spectrum of the shared cell can be shared
