detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

The embodiments of the present invention provide a method and an apparatus for selecting a baseband board according to the existing problems.

First embodiment

Referring to FIG. 1, a first embodiment of the present invention provides a method for selecting a baseband board, including:

Step 101: Acquire a plurality of baseband resource usage data of the baseband board.

A base station includes a main control board and multiple baseband boards. The main control board provides signaling processing and resource management functions for other boards, including configuration management, device management, software management, performance monitoring, active/standby switchover, and alarm. The baseband board mainly implements the baseband signal processing function and can support the baseband processing related functions of the carrier. When establishing a wireless link, it is necessary to consider which baseband board to select based on the resource usage of the baseband board.

The baseband resource usage data may be CPU usage, logical channel unit resource occupancy, CPU usage of the digital signal processor, and multipath search resource occupancy.

Step 102: Count each baseband resource usage data to generate a palette policy indication message.

Specifically, all the baseband resource usage data of the baseband board is used to comprehensively consider all the baseband resource usage data, and a board selection indication policy is generated to avoid a bottleneck resource alarm in an external field.

Step 103: Send a board selection policy indication message to the base station, so that the base station establishes a radio link according to the board policy indication message.

The device sends a board selection policy indication message to the base station, and the base station establishes a radio link according to the board policy indication message. It should be noted that the method for establishing a radio link by the base station may be to preferentially select the baseband board or to stagger the baseband board.

In the above embodiment of the present invention, step 102 includes:

In the first step, when the at least one baseband resource usage data is higher than the corresponding preset trigger threshold, the first palette policy indication message is generated, where the first palette policy indication message is used to indicate that the base station skips when establishing the radio link. Baseband board.

The trigger threshold may be a bottleneck threshold of the resource usage data. When the baseband resource usage data of the at least one baseband board is higher than a preset trigger threshold, the resource usage of the baseband board has reached a bottleneck, and the wireless chain is not suitable. Therefore, the first palette policy indication message is generated, so that the base station skips the baseband board when establishing the radio link, and selects other baseband boards to avoid affecting the service processing rate.

In the second step, when all the baseband resource usage data are not greater than the corresponding preset recovery threshold, the second palette policy indication message is generated, and the second palette policy indication message is used to indicate that the base station preferentially selects when establishing the wireless link. Baseband board.

Wherein, when all baseband resource usage data of the baseband board is below a corresponding preset recovery threshold, it indicates that the current resource usage of the baseband board is at a lower load, and it is suitable to establish a wireless link, and perform a wireless chain. The baseband board is preferentially selected when the road is connected, which is beneficial to improve system performance and enable the base station to accommodate more users.

Further, the first step described above includes:

The CPU usage is the CPU usage of the baseband board. When the CPU usage is high, the image system runs at a higher rate. Therefore, when the CPU usage is higher than the default CPU usage threshold, the first board policy indication message is generated. The baseband board is skipped when the base station establishes a wireless link.

The CPU usage of the digital signal processor is the CPU usage of the digital signal processor of the baseband board, indicating the operating rate of the digital signal processor. When the CPU usage threshold is higher than the preset digital signal processor, the generation is generated. A palette policy indication message causes the base station to skip the baseband board when establishing a wireless link.

The logical channel unit typically includes a control channel unit and a traffic channel unit, wherein the control channel unit is configured to transmit control plane information and the traffic channel unit is configured to transmit user plane information. When the logical channel unit resource usage rate is higher than the preset logical channel unit resource usage threshold, the data transmission is affected. Therefore, when the threshold is higher than the preset trigger threshold, the first board policy indication message is generated, so that the base station is established. The baseband board is skipped when the wireless link is used.

Multipath search is to search for multiple paths of the radio signal from the transmitting antenna to the receiving antenna. When the multipath search resource occupancy rate is higher than the preset multipath search resource occupancy trigger threshold, the multipath search of the base station is affected. Therefore, A first palette policy indication message is generated to enable the base station to skip the baseband board when establishing a wireless link.

Further, the second step above includes:

The baseband resource usage data can be set according to actual conditions.

When the CPU usage, the CPU usage of the digital signal processor, the logical channel unit resource occupancy rate, and the multipath search resource occupancy rate are lower than or equal to the corresponding recovery thresholds, it indicates that the current resource usage of the baseband board is In the case of lower load, it is suitable to establish a wireless link, and the baseband board is preferentially selected when performing wireless link connection, which is beneficial to improve system performance.

In the above embodiment of the present invention, step 101 includes:

Before obtaining the data of the plurality of baseband resources of the baseband board of the base station, it is necessary to determine whether the resource adaptive switch is enabled, and when the base station is enabled, the base station is allowed to obtain the baseband resource usage data and perform the board selection.

The trigger threshold and the recovery threshold of the data are used. It should be noted that the values in Table 1 can be configured according to the actual situation of the base station.

Table 1:

According to the trigger threshold and the recovery threshold of the baseband resource usage data in Table 1, if the resource exceeds the trigger threshold or is lower than the recovery threshold, the baseband resource usage is reported to the baseband resource decision module.

The resource decision module performs a board selection instruction according to the baseband resource usage reported by the baseband resource statistics module, and the decision method is: if any of the baseband resource usage data exceeds the trigger threshold, the board selection indication message is sent to the dynamic palette module, the message The middle indicator indicates that the equalization board is required, that is, the baseband board is skipped when the wireless link is established; if all the baseband resource usage data is lower than the recovery threshold, the board selection instruction message is sent to the dynamic palette module, and the message indicates that the input preference board is required. , That is, the baseband board is preferentially selected when the wireless link is established. The resource decision module itself also determines that the board selection policy needs to be adjusted according to the baseband resource usage reported by the baseband resource statistics module.

The dynamic palette module establishes a wireless link according to the palette selection report reported by the resource decision module.

In the foregoing embodiment of the present invention, the baseband resource statistics module counts the usage of various resources of the baseband board, and considers the bottleneck resource problem that has occurred in the external field. The statistical resources include at least the CPU usage of the digital signal processor and the CPU usage of the baseband board. Rate, multipath search resource occupancy rate, and logical channel unit resource occupancy rate. When any baseband resource usage data reaches a trigger threshold or all baseband resource usage data is lower than the recovery threshold, the reporting condition is met, and the resource usage is reported to Baseband resource decision-making module; the baseband resource decision-making module makes a decision according to the use of various resources of the baseband board provided by the baseband resource statistics module, generates a board selection strategy of the preferential board or the balanced board, and reports to the dynamic board module; the dynamic board module The dynamic panel selection is performed according to the palette indication given by the baseband resource decision module. The embodiment of the present invention solves the problem that the dynamic panel selection is too simple according to the resource occupancy rate of the logical channel unit of the baseband board, and cannot deal with various bottleneck resources of the external field.
