Problems solved by technology

[0007] 1. Due to the centralized storage method, the FLASH on the main control board needs to store all the business software and FPGA files of the service boards supported by the subrack, so the FLASH needs to have a large capacity; but in actual use, the subrack The business software and FPGA files used by the service board only occupy part of the storage in the FLASH of the main control board, resulting in a waste of storage capacity;
[0008] 2. Since the business software is run in a bundled hybrid method, all the software in the FLASH of the main control board must be moved to the memory to decompress and run during operation, which takes up a lot of memory and increases the pressur

Embodiment Construction

[0050] In order to solve the problem of waste of storage capacity of the main control board and high pressure on RAM in the centralized control solution system, when a new service board is added or the software of the service board is upgraded, it is necessary to manually reset the main control board, which will affect the business process and increase the system maintenance cost. The embodiment of the present invention provides a method for dynamically loading a service board.

[0051] A method for dynamically loading service boards, comprising:

[0052] Such as figure 2 As shown, 201. If it is detected that the service board is online, the service software and the programmable logic file of the service board are obtained from the storage chip of the service board;

[0053]202. Load the programmable logic file for the service board;

[0054] 203. Run the service software of the service board to complete the configuration of the service board.

[0055] In the embodiments o...

Abstract

The embodiment of the invention discloses a method for dynamically loading service boards and a dynamic loading system, relates to the communication field and solves the problems of storage capacity waste of a main control board and great RAM pressure, and influence on operating services caused by reloading service board software and FPGA files in communication equipment adopting a centralized control scheme. The method comprises the following steps: when detecting that the service board is on-line, acquiring service software and a programmable logic file of the service board from a storage chip of the service board; loading the programmable logic file for the service board; and running the service software of the service board to complete the configuration of the service board. The method for dynamically loading the service boards and the dynamic loading system can be applied to constructing a centralized control scheme of communication equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for dynamically loading a service board and a dynamic loading system. Background technique [0002] The communication equipment subrack adopting the centralized control scheme is composed of the main control board and the service board. Such as figure 1 As shown, the main control board 101 is used to complete functions such as online and offline control of the service board, service configuration of the service board, and alarm collection of the service board; the service board 102 is used to provide different types of services. The main control board 101 has a small CPU system 103, which includes: a CPU 104, a flash memory 105 (FLASH), and a random-access memory 106 (random-access memory, RAM). The service board 102 includes: a complex programmable logic device 107 (Complex Programmable Logical Device, CPLD), a field programmable gate array 108 (Field Programmable Gate Array...
