Baseband power output with DO carrier frequency.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 is a schematic structural diagram of an embodiment of a base station control system of a CDMA system according to the present invention. As shown in FIG. 1, the control system includes: a base station operation and maintenance subsystem 10, a base station database subsystem 20, and a base station carrier frequency control subsystem 30; among them,

The base station operation and maintenance subsystem 10 is configured to set the working time of the IX and DO carrier frequencies that need to be converted to each other, and the IX and DO carrier frequencies that need to be converted, and synchronize the set data to the foreground base station database subsystem 20;

The base station database subsystem 20 is configured to synchronize the working times of the IX and DO carrier frequencies and the IX and DO carrier frequencies to the base station carrier frequency control subsystem 30;

The base station carrier frequency control subsystem 30 is configured to control the baseband power output of the IX and DO carrier frequencies according to the working time of the carrier frequency.

Specifically, the base station operation and maintenance subsystem 10 is configured to set the working time of the IX and DO carrier frequencies and the IX and DO carrier frequencies according to the characteristics of the commercial office traffic. For example, base station operation and maintenance subsystem 10 According to the IX daytime carrier frequency is busy, the traffic volume is large, and the DO carrier frequency is idle, the working time of setting the IX carrier frequency is the same as the time of the IX traffic volume, that is, the working time of setting the IX carrier frequency is daytime; For the DO carrier frequency is busy at night, the traffic is large, and the IX carrier frequency is idle, the working time of setting the DO carrier frequency is the same as the time of the large DO traffic, that is, the working time of setting the DO carrier frequency is night. Further, the base station operation and maintenance subsystem 10 can also limit the mutual conversion of the IX and DO carrier frequency working times to be incapable of overlapping, and if the settings overlap, prompting an input error. Further, the base station operation and maintenance subsystem 10 can simultaneously set a plurality of pairs of mutually converted IX and DO carrier frequencies. After the above setting is completed, the base station operation and maintenance subsystem 10 synchronizes the set data (i.e., the data including the IX and DO carrier frequencies and their working hours) to the base station database subsystem 20.

The base station carrier frequency control subsystem 30 is configured to control the baseband power output of the IX and DO carrier frequencies based on the I X and DO carrier frequency operating times synchronized by the base station database subsystem. Specifically:

The base station carrier frequency control subsystem 30 sets a carrier frequency on or carrier frequency off timer for each IX and DO carrier frequency under the base station according to the carrier frequency working period synchronized by the base station database subsystem 20, and controls the carrier frequency in the following manner. :

When the carrier frequency on timer expires, the carrier frequency baseband power is normally output; the overhead message is updated according to the state of the carrier frequency, and the terminal is notified to lock on the available carrier frequency.

When the carrier frequency off timer expires, the baseband power output of the carrier frequency is turned off; before the carrier frequency is turned from on to off, a frequency switching is initiated on the call of IX or DO on the carrier frequency to be turned off, so that the carrier frequency is to be turned off. The call is switched to other available carrier frequencies to ensure that the call will not be dropped after the carrier frequency is turned off.

2 is a flowchart of a method for controlling a base station of a CDMA system according to the present invention. As shown in FIG. 2, the base station control method of the CDMA system of the present invention includes the following steps:

Step S10, the base station operation and maintenance subsystem sets the IX and DO carrier frequencies and their working times that need to be converted, and synchronizes the set data to the foreground base station database subsystem;

Specifically, the base station operation and maintenance subsystem of the embodiment of the present invention can be used by the operation and maintenance personnel to set the IX and DO carrier frequencies and their working hours on which the mutual conversion needs to be performed. The base station operation and maintenance subsystem is used to set the working time of the IX and DO carrier frequencies and their IX and DO carrier frequencies according to the characteristics of the commercial office traffic. For example, the base station operation and maintenance subsystem is busy according to the IX daytime carrier frequency, the traffic volume is large, and the DO carrier frequency is idle. The working time of setting the IX carrier frequency is the same as the time of the IX traffic volume, that is, setting the IX carrier frequency. The working time is daytime; for the DO carrier frequency is busy at night, the traffic is large, and the IX carrier frequency is idle, the working time of setting the DO carrier frequency is the same as the time of the DO traffic, that is, setting the DO carrier frequency. The time is night. The base station operation and maintenance subsystem also limits the working time of the IX and DO carrier frequencies that are mutually converted and cannot overlap. If the settings overlap, the input error is prompted. Further, the base station operation and maintenance subsystem can simultaneously set multiple pairs of mutually converted IX and DO carrier frequencies. After the setup is complete, the base station operation and maintenance subsystem synchronizes the data to the base station database subsystem.

Step S20: The base station database subsystem synchronizes the IX and DO carrier frequencies and their working times to the base station carrier frequency control subsystem.

Step S30, the base station carrier frequency control subsystem controls the baseband power output of the IX and DO carrier frequencies according to the working time of the carrier frequency;

Specifically, the base station carrier frequency control subsystem may separately set a carrier frequency on or a carrier frequency off timer for each IX and DO carrier frequency of the base station according to a carrier frequency working period synchronized by the base station database subsystem, and control the following manner: Carrier frequency:

3 is a flowchart of another embodiment of a base station control system of a CDMA system according to the present invention. As shown in FIG. 3, the process includes the following steps:

Step S101, setting IX and DO carriers that need to be converted to each other and IX that need to be converted to each other And the working time of the DO carrier is synchronized; for example, the operation and maintenance personnel set the IX and DO carrier frequencies and their working hours that need to be converted to each other in the base station operation and maintenance subsystem 10. After setup, the base station operation and maintenance subsystem 10 synchronizes the data to the base station database subsystem 20.

Step S102, setting a carrier frequency off and on timer according to the carrier frequency working time; for example, the base station carrier frequency control subsystem 30 according to the carrier frequency working period synchronized by the base station database subsystem 20, and each IX and DO carrier frequency under the base station Set the carrier frequency on or carrier frequency off timer separately.

Step S103: When the carrier frequency on timer expires, the baseband power output of the carrier frequency is turned on; and the base station carrier frequency control subsystem 30 turns on the baseband power output of the carrier frequency on timer corresponding to the carrier frequency.

Step S104: Update the overhead message of the cell according to the carrier frequency state change; the base station carrier frequency control subsystem 30 updates the overhead message, adds the opened carrier frequency to the overhead message, and enables the terminal in the idle state to be locked at the carrier frequency, and The service can be established on the carrier frequency (if it is the IX carrier frequency, the IX service can be performed; if it is the DO carrier frequency, the DO service can be established), and then the process goes to step S102.

Step S105, when the carrier frequency off timer expires, initiate a frequency switching for the call on the carrier frequency to be turned off; for example, the base station carrier frequency control subsystem 30 updates the overhead message, and removes the off carrier frequency from the overhead message to prevent idle. The terminal is locked to the carrier frequency that is about to be turned off. Moreover, the base station carrier frequency control subsystem detects that the timer corresponds to the established call on the carrier frequency, initiates a frequency switching for each call, and switches to another available carrier frequency to prevent the call drop after the carrier frequency is turned off.

Step S106, turning off the carrier frequency baseband power output. The base station carrier frequency control subsystem 30 turns off the baseband power output of the corresponding carrier frequency.

The same is included in the scope of patent protection of the present invention.
