The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

1 is a schematic diagram of a method for paging traffic control in a CDMA system according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:

Step S101: After receiving the paging message, the BSC determines the destination BTS of the paging message. Step S102: The BSC determines whether the paging capability of the destination BTS exceeds a paging capability threshold.

Step S103: If not, the BSC forwards the paging message to the destination BTS. Otherwise, the BSC does not forward the paging message to the destination BTS.

2 is a flow chart of a method for paging traffic control in a CDMA system according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

Step S201: The board on the BSC side sets a paging capability threshold for each BTS.

The paging restriction function mode switch can be configured in the background of the BSC to flexibly control whether the board on the BSC side performs flow control on the paging message sent to the BTS.

The flow control of the paging message sent to the BTS by the board on the BSC side is performed according to the BTS. The BSC background configuration flexibly configures the paging capability threshold of each BTS for each BTS processing capability (the processing capability of the BTS is reported to the BSC by each BTS according to its own processing capability). The paging capability threshold is the maximum number of paging times that the board on the BSC side sends to the BTS in a unit time set for each BTS according to the processing capability of each BTS. There are default values and range protection limits when configured in the background. Setting the default value can reduce the workload of the configurator, and can prevent the user from forgetting to set the paging capability threshold of some BTSs and causing paging problems. Setting the range threshold for paging capability can effectively protect the normal operation of the base station and prevent setting errors or accidents from being able to page.

Step S202: The board on the BSC side determines whether the current paging message needs to be sent to the current BTS. The destination BTS to which the paging message is sent may be multiple. The board on the BSC side determines whether the current BTS is the destination BTS of the current paging message. If yes, step S204 is performed; otherwise, step S203 is performed.

Step S203, selecting the next BTS as the current BTS, and returning to step S202.

Step S204: The board on the BSC side determines the state of the function BTS paging message function mode switch.

The board on the BSC side determines the purpose of the paging message. The paging message function mode switch state of the BTS. If the status of the destination BTS is "ON", step S206 is performed, otherwise step S205 is performed.

Step S205: Perform a prior art overload control process.

After the prior art overload control process is executed, step S203 is performed.

Step S206: The board on the BSC side determines whether the paging capability threshold of the destination BTS is within the protection range.

The board on the BSC side determines whether the maximum number of pagings of the destination BTS is within the effective value protection range. If it is in the protection range, step S207 is performed; otherwise, step S205 is performed.

Step S207: The board on the BSC side determines whether the number of paging messages sent to the destination BTS exceeds the paging capability threshold.

The board on the BSC side determines whether the number of paging messages sent to the destination BTS exceeds its paging capability threshold, that is, the maximum number of pages. If yes, step S208 is performed, otherwise step S209 is performed.

Step S208, the paging message is not sent to the destination BTS.

If the number of paging messages sent to the BTS has exceeded the paging capability threshold, the paging message is not sent to the destination BTS, and step S203 is performed.

Step S209, accumulating the number of paging messages sent to the destination BTS.

The number of paging messages sent to the destination BTS is accumulated once, and it is judged whether the accumulated time exceeds the set unit time. If it is exceeded, the number of paging messages is reset to zero.

Step S210, forwarding a paging message to the destination BTS. After the paging message is forwarded to the destination BTS, step S203 is performed.

3 is a schematic structural diagram of an apparatus for paging traffic control in a CDMA system according to an embodiment of the present invention. As shown in FIG. 3, the apparatus includes a setting module 1, a determining BTS module 2, a determining module 3, and a processing module 4; ,

Setting module 1 is configured to set a paging capability threshold for each BTS;

Determining a BTS module 2, configured to determine a destination BTS of the paging message after receiving the paging message;

The processing module 4 is configured to forward the paging message to the destination BTS when the paging capability of the destination BTS does not exceed the paging capability threshold, and not forward the paging message to the destination BTS.

Specifically, the setting module 1 is configured to set a paging capability threshold. The flow control of the paging message sent to the BTS by the board on the BSC side is performed according to the BTS. The BSC background configuration flexibly configures the paging capability threshold of each BTS for its own processing capability reported by each BTS. There are default values and range protection limits when configured in the background. Setting the default value can reduce the workload of the configurator, and can prevent the user from forgetting to set the paging capability threshold of some BTSs and causing paging problems. The protection of the paging capability threshold setting range can effectively protect the normal operation of the base station, prevent setting errors or accidentally causing paging failure. The paging capability threshold is the maximum number of paging times that the board on the BSC side sends to the BTS in a unit time set for each BTS according to the processing capability of each BTS.

The BTS module 2 is determined to be polled to determine whether the current BTS is the destination BTS.

The determining module 3 is configured to determine whether the paging capability of the destination BTS exceeds a paging capability threshold. When it is determined that the BTS module 2 determines that the current BTS is the destination BTS of the paging message, the determining module 3 determines the function mode switch state of the destination BTS paging message of the current paging message, if the state of the destination BTS is "on", Further determining whether the maximum number of pagings of the destination BTS is present Within the scope of the protection of effectiveness, if it is in the protection scope, it continues to determine whether the number of paging messages sent to the destination BTS exceeds its paging capability threshold, that is, the maximum number of pagings.

The processing module 4 is configured to perform corresponding processing of forwarding the paging message according to the judgment result of the determining module 3. If the number of paging messages sent to the destination BTS exceeds its paging capability threshold, the processing module 4 does not send a paging message to the destination BTS, otherwise, the paging message sent to the destination BTS is accumulated once, and The destination BTS forwards the paging message. At the same time, it is judged whether the accumulated time exceeds the set unit time, and if it is exceeded, the number of paging messages is reset to zero.

In summary, the present invention determines whether to send a paging message to the destination BTS by comparing the paging capability of the destination BTS with its paging capability threshold, and solves the board paging overload on the BSC side and the paging overload of the BTS base station. And the problem that the paging overload causes the BTS to drop off, fully utilizes the processing capabilities of various base stations, and well coordinates the relationship between the board, the base station overload, and the paging processing capability.

Although the invention has been described in detail above, the invention is not limited thereto, and various modifications may be made by those skilled in the art in accordance with the principles of the invention. Therefore, modifications made in accordance with the principles of the present invention should be construed as falling within the scope of the present invention.
