The specific implementation process is described in detail in the method embodiment, and details are not described herein. In order to make the technical solutions and implementation methods of the embodiments of the present invention clearer, the implementation process will be described in detail below in conjunction with the preferred embodiments. Embodiment 1 This embodiment provides a method for BHCA acquisition and capacity expansion analysis of a base station system, which is used for BHCA capacity expansion analysis based on a base station board. The method includes the following steps: Step 1: For a BHCA of a base station board, A periodic sampling of a small granularity (for example, N seconds) is performed. Step 2: The board is converted into a traffic factor by using a proportional coefficient in N seconds to obtain a BHCA in the N seconds of the board. Step 3: Normalize the BHCA data collected by each board. The BHCA warning line (that is, the predetermined BHCA alarm threshold) of different types of boards is unified by the normalized processing mode, which reduces the complexity of the expansion analysis caused by the difference in BHCA design capacity of each board. Step 4: Determine whether the board needs to be expanded or not, and provide an alarm display for the board that needs to be expanded. Through the above steps, a high-precision and accurate BHCA acquisition and processing method is provided, and an evaluation and early warning system for "thermometer" mode (ie, bar chart) can be further established for each board. The above collection and processing methods can ensure accurate collection of BHCA for each board, especially for the average BHCA of the board is not high, and the instantaneous BHCA high can be detected and analyzed, and the base station system is advanced in advance. The board capacity is insufficient to perform alarms to prevent the traffic from being too high, which affects the normal operation of the system and ensures the normal operation of the base station system. Embodiment 2 This embodiment provides a single-board BHCA acquisition and expansion analysis apparatus for a base station system, and the apparatus can be used to implement the BHCA collection and processing method in the first embodiment. In the implementation process, the device may include: a BHCA acquisition module, a BHCA normalization processing module, an alarm display module, and a thermometer mode display module. The BHCA acquisition module is configured to complete various service functions in the wireless communication system, and collect statistical data at key points (for example: call, handover, release, SCH scheduling) related to the BHCA service; BHCA normalization The processing module is configured to normalize the BHCA reported by the data collection module according to the BHCA design capacity of each board to obtain a normalized BHCA value of the board; the alarm display module is set to be normalized according to the normalized The BHCA value of the board and the BHCA warning line (preset threshold of the BHCA) are used to determine whether the BHCA of the board exceeds the warning line and whether an alarm display is required. The thermometer mode display module is set to the condition selected by the user (for example, time). Range, board type, and grouping method. The BHCA is displayed in a thermometer (such as a histogram) and provided to the user for expansion analysis. The BHCA expansion analysis method of the base station system in the embodiment of the present invention may include the following steps: Step A: After the board is powered on (or after the timer expires), the BHCA collection module starts the collection timer; The incoming, outgoing, or switching triggers a business process. After the BHCA acquisition module completes the entire process of the above business process, it also collects BHCA-related data at key points of the business process. The corresponding message cost varies according to the signaling process of each service. To calculate the total BHCA of various services on the board according to the unified standard, statistics can be performed as follows: When the timeout comes, the service cost corresponding to the key points of the above business process are: al, a2, a3 ... an, and the BHCA conversion coefficients corresponding to the above services are: bl, b2, b3 ... bn, then the total board BHCA = Al*bl+a2*b2+a3*b3+ ... +an*bn; After the timer expires, the BHCA acquisition module sends the acquired BHCA data to the BHCA normalization processing module. Step B: After receiving the BHCA data, the BHCA normalization processing module saves the BHCA data in the storage medium; normalizes the BHCA data according to the BHCA design capacity of each board. The normalized processing method can be: Assume that the BHCA values corresponding to the boards B1, B2, B3, ... Bn are: Hl, H2, H3 ... Hn, and the BHCA design capacities of the boards are Dl, D2, respectively. D3 ... Dn, then, the normalized boards BHCA utilization rates corresponding to the boards B1, B2, B3 ... Bn are: H1/D1, H2/D2, H3/D3 ... Hn/Dn. Step C: The warning display module is configured to determine whether the BHCA utilization of the normalized board exceeds the warning line (that is, the threshold of the preset BHCA) according to the warning line set by the system, and alarms the board that exceeds the warning line. example For example, the alarm method can be: When a board is in the continuous N times (for example, 3 times), the normalized board BHCA utilization rate exceeds the warning line, then the alarm is reported on the board; If the BHCA utilization rate of the normalized board is lower than the warning line in a continuous N-cycle, the alarm is reported on the board. In this way, ping-pong alarms can be avoided and the number of alarms can be reduced. Step D: The user can select the board, the time range, and the statistical grouping mode in the thermometer mode display module. The module pairs the specified board, specifies the time period, and groups according to the specified mode, and the BHCA of the normalized board. The expansion analysis is performed, and the statistical results can be displayed in a thermometer manner (for example, a histogram). The standard of the warning lines of all the boards is unified, which is convenient for users to quickly find the boards that need to be expanded. Through the above-mentioned device, the BHCA data of the board is collected, and the collected data is normalized, and the expansion warning lines of various types of boards are unified, and the average BHCA of the base station in the base station system is realized. It is not high, but the instantaneous BHCA is detected and analyzed to ensure that the system capacity alarm is advanced, and the traffic is not affected to affect the normal operation of the system.

Step S504: The terminal user accesses, releases, or switches to trigger a service process, and the BHCA collection module 42 completes the entire process of the foregoing service process, and collects BHCA related data at key points of the business process. Step S506, determining the service type, and calculating the board BHCA according to the BHCA conversion coefficient of the service type. Because the signaling process of each service is different, the corresponding message cost is different. To calculate the total BHCA of various services on the board according to the unified standard, the following algorithm is provided: Assume service a1, service a2, service A3 ... business an, the corresponding BHCA conversion coefficients are: bl, b2, b3 ... bn, then, the board total BHCA = al * bl + a2 * b2 + a3 * b3 + ... + an * bn. Step S508, determining whether the timer expires. If it has not timed out, step S504 is performed, otherwise, step S510 is performed.

If the buffer of the reporting module is not full, step S502 is performed; otherwise, step S514 is performed. In step S514, the BHCA acquisition module 42 copies the data of the buffer into the transmission buffer. In step S516, the reporting buffer is cleared. Step S518, the data of the sending buffer is sent to the BHCA normalization processing module 34.

In step S704, the normalized BHCA utilization rate is scanned, and according to the warning line set by the system (ie, the BHCA threshold), it is determined whether the normalized board BHCA utilization exceeds the warning line. In the implementation, the alarm algorithm can be as follows: When the BHCA utilization rate of the normalized board exceeds the warning line in a continuous N-cycle, the board reports the alarm; when a board is continuous If the BHCA utilization rate of the normalized board is lower than the warning line, the alarm is reported on the board. Thereby avoiding ping-pong alarms and reducing the number of alarms. The specific steps may be: if the warning line is exceeded, step S706 is performed, and if the warning line is not exceeded, step S714 is performed. In step S706, it is determined whether the normalized board BHCA utilization rate exceeds the warning line for N times (for example, N=3). If yes, step S708 is performed. Otherwise, step S704 is performed. Step S708, it is determined whether the board has been It is the BHCA utilization alarm status. If the alarm is in the alarm state, the operation is not performed.
