Method and device for dynamically loading multi-system application program

Abstract

The invention discloses a method and a device for dynamically loading a multi-system application program. The method includes that a real time operating system (RTOS) is loaded to an operating system prefecture, each system application program is loaded to a copy area, script documents are loaded to a linkage script area, and configuration words of a currently-operated system application program are filled; the script documents are analyzed through the configuration words, and a corresponding module application program is loaded from the copy area to an operation area; a memory management unit (MMU) configuration table is built, and a mapping relation of the module application program between storing addresses of the copy area and the operation area is built; and an application program of the operation area is started, and an MMU achieves conversion of storing addresses of symbols in the module application program according to the mapping relation. Random combination of the systems is finished in an application program loading stage, address conversion of the copy area and the operating area is achieved through the MMU, only one engineering project of a single system is built during encoding, and support of one base station for the multiple systems is achieved with less code quantity.

Description

technical field [0001] The invention relates to a dynamic loading technology of an embedded software system, in particular to a dynamic loading method and device for multi-standard application programs. Background technique [0002] In today's cost strategy, people always hope to achieve the most applications with the least hardware, and there are more and more demands for this scenario. For example, with the rapid development of mobile communication technology, there are more and more protocol standards, including UMTS, CDMA2000, TD-SCDMA, WiMAX, LTE, etc., which also put forward higher requirements for the design of base stations. In the 2G era, a base station only needs to meet one standard, because the user's mobile communication terminal only supports one of GSM and CDMA standards, but with the advent of the 3G era, more standards have been brought for users to choose. Communication terminals are differentiated with different standards. There will be terminals of multi...
