Mobile communication control method, base station controller, base station and system

This application claims priority to Chinese Patent Application No. 200810067711. 5, entitled "Mobile Communication Control Method, Base Station Controller, Base Station and System", all of which are submitted to the Chinese Patent Office on June 6, 2008. The content is incorporated herein by reference.

TECHNICAL FIELD The present invention relates to the field of wireless communication technologies, and in particular, to a mobile communication control method, a base station controller, a base station, and a system. Background technique

In a mobile communication system, such as Global System for Mobile Communications (GSM), as shown in FIG. 1, a typical GSM network structure may generally include: a mobile station 101 (MS, Mobile Station), a base station. 102 (BTS, Base Transceiver Station), Base Station Controller 103 (BSC, Base Station Contrailer), Mobile Switching Center 104 (MSC, Mobile Switching Center). The MS communicates with the BTS through the Um interface, the BSC and the BTS communicate through the Abis interface, and the MSC and the BS C communicate through the A interface. A base station typically includes a base station including a transceiver (TRX, Transceiver), also called a carrier frequency, for receiving and processing signals of the terminal.

The carrier frequency generally refers to a network element that can serve the full-rate traffic channel of 8 full-duplex communications. If no slow frequency hopping is used, one carrier frequency usually serves one RF carrier, and the carrier frequency can also serve two carriers. A carrier frequency can provide full-rate traffic channels for 16 full-duplex communications. The carrier frequency also provides a channel between the uplink and downlink signals in the antenna feeder system and the baseband portion, and assumes the control function of a part of the wireless interface. The carrier frequency can usually include: baseband control, medium RF, and power amplifier. At present, the energy saving and consumption reduction of base stations has become an issue of increasing concern. Therefore, how to reduce the power consumption of the carrier frequency and thus reduce the energy consumption cost of operators has become the focus of various manufacturers in the industry. Some existing methods for reducing the power consumption of the carrier frequency are static. The method used is usually to reduce the power consumption of the base station by manually turning off the TRX power of some base stations, for example, by manually issuing commands in the BSC. The control base station operates the TRX to put the carrier frequency into the power saving mode. When it is considered that the TRX needs to be activated in a certain period of time, the BSC manually issues a command to activate the carrier frequency to work in a normal state. This manual method is time-consuming and labor-intensive, and cannot be processed in real time, and turning off the power of the TRX during a certain period of time may also affect the service, such as when there is a sudden large traffic access or When the data service is accessed, the carrier frequency cannot be started in time by manual means, which may result in the call drop or the data service cannot be completed, which affects the user experience.

In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be described in detail below with reference to the embodiments and drawings. The illustrative embodiments of the present invention and the description thereof are intended to explain the present invention, but are not intended to limit the invention. A mobile communication control method according to Embodiment 1 of the present invention, as shown in FIG. 2, includes the following steps: Step 201: Acquire a number of occupied channels of a carrier frequency;

The technical solution provided by this embodiment, when referring to a GSM network shown in FIG. 1, is described by taking GSM as an example: the base station controller can obtain the channel usage of the carrier frequency in the base station under the base station controller, for example, The base station controller can acquire the number of channels (or the number of idle channels) occupied by a certain carrier frequency in the base station. A base station may be composed of a plurality of cells, each cell serving a certain area and a certain number of users, and the cell is composed of a plurality of carrier frequencies, but usually at least one carrier frequency is configured. By analyzing the channel usage of the carrier frequency in the base station, the traffic volume and data traffic carried by the cell in which the carrier frequency is carried can be obtained.

Step 202: Detect whether the number N of occupied channels of the carrier frequency is zero;

If it is detected that the occupied channel number N of the carrier frequency is equal to zero, then step 203 is performed;

If the number of occupied channels N of the carrier frequency is not equal to zero, the method flow in this embodiment may end; of course, the method flow in this embodiment may not end, for example, the base station controller may continue to detect and acquire the carrier frequency of the base station. If the channel condition data is occupied, go to step 201, or continue to detect the occupied channel condition data of the base station carrier frequency according to a preset time period, and then go to step 201, so that real-time acquisition of each carrier frequency in the base station can be realized. Channel usage.

Step 203: Turn off the RF part power supply of the carrier frequency.

In this embodiment, determining whether to turn off the radio frequency power supply of the carrier frequency according to the condition of the carrier frequency idle channel, for example, when all channels of the carrier frequency are idle and not occupied (this may occur at night) Of course, during a certain period of the day, the traffic volume or data traffic may also be low, causing all the carriers of the carrier frequency to be idle and unoccupied. That is, when the number of occupied channels of the carrier frequency is zero, the base station controls The controller can issue a control command to enter the power-saving working mode and turn off the power supply of the radio frequency component of the carrier frequency.

With the mobile communication control method provided in this embodiment, the radio frequency power supply of the carrier frequency is turned off by using the idle working time of the carrier frequency, thereby reducing the power consumption of the carrier frequency without affecting the service. This method can also be used in wireless access communication systems of different standards, such as Universal Mobile Telecommunications System (UMTS), such as Code Division Multiple Access (CDMA), such as Time Division-Synchronous Code (TD-SCDMA, Time Division-Synchronous Code) Division Multiple Access), and other wireless access communication systems that need to adjust carrier frequency power switches to reduce power consumption based on traffic and data traffic. Embodiment 2:

Step 303: Turn off the power supply of the radio frequency component of the carrier frequency;

The step 303 can adopt the technical solution provided in step 203 in the first embodiment.

Step 304: Obtain an occupied channel number N of the cell where the carrier frequency is located;

Step 305: Determine whether the number N of occupied channels of the cell in which the carrier frequency is located meets a preset condition. In this step, the following may specifically include:

For example, the preset condition may be: The base station controller finds that the channel occupancy of the cell where the carrier frequency is located has reached full load by detecting statistics, and it can be said that all channels under the cell where the carrier frequency is located are already occupied, and there is no idle. Channel for new traffic or data service access;

For example, in another implementation scenario, the preset condition may be: The base station controller finds that the number of channels occupied by the cell where the carrier frequency is located has reached a preset value by detecting statistics.

If the preset condition is met, the process proceeds to step 306; if the preset condition is not met, the method flow in this embodiment may end; the method flow in this embodiment may not end, for example, the base station controller may continue to obtain Channel occupancy of the cell, step 304, or the base station control The device may continue to acquire the channel occupancy of the cell according to a preset time period, and the process may be continued.

304, in this way, real-time access to the channel usage of the cell where the carrier frequency is located can be realized.

To facilitate understanding and disclosure of the communication control method provided by the embodiment of the present invention, two specific practical application scenarios are as follows:

Usually, a single carrier frequency (a case where one carrier is supported per carrier, a full-rate traffic channel providing 8 full-duplex communication per carrier) can provide 8 channels, and the carrier frequency can be accessed at most 8 times at the same time. A user can fill up to 8 channels at a full load; a cell can usually be configured with multiple carrier frequencies, for example, one cell is configured with 2 carrier frequencies, so that the cell has a total of 16 channels, and if only 8 channels are occupied, Then, one of the carrier frequencies can be turned off, for example, at least the radio frequency part of the power supply can be turned off; if the number of channels to be used by the cell exceeds eight, another carrier frequency needs to be turned on; of course, it can also be set, when If one of the carrier frequency channels in the cell is already full, another carrier frequency is turned on, so that the channel for the newly accessed service can be provided in time.

When a single carrier frequency supports dual carriers, this carrier frequency can also be called double-density carrier frequency, then a dual-density carrier frequency can provide 16 full-duplex communication full-rate traffic channels, at the same time. 16 users are connected, and the full load is 16 channels; a cell can usually be configured with multiple carrier frequencies, for example, one cell is configured with 2 dual-density carrier frequencies, so that the cell has a total of 32 channels, if only occupied If there are 16 channels, then one of the carrier frequencies can be turned off, such as turning off at least the RF power of the carrier frequency; if the number of channels that the cell needs to use exceeds 16, you need to open another one; of course, you can also set When the channel of one carrier frequency in the cell has all occupied, another carrier frequency is turned on, so that the channel for the newly accessed service can be provided in time.
