Abstract


PHS (Personal Handy phone System) technology has been tremendous development in China and UT Starcom , ZTE and other large enterprises will improve after PHS system to achieve major success in the country . PHS system extending range broader solve PHS disadvantage in the application of which becomes an important problem . This article with the UT Starcom new products QBOX for the application background , highlights and research on the embedded real-time operating system uC/OS- Ⅱ PHS private base station . First analysis of the PHS air interface features and call agreement , then starting from product design and production testing phase , described the uC/OS- Ⅱ operating system migration to the development work on the the RENESAS company H8S/2643 chip , as well as how to use the uC / OS-Ⅱ work in coordination with various modules . Also resolved a 2643 chip ROM upgrade program agreement process and algorithm flow . Reference both algorithm is used to prevent priority inversion phenomenon which uC/OS- Ⅱ operating system has been the priority of the Law on the Protection and priority inheritance laws , improved , priority exchange algorithm prevent priority inversion . Finally, from the test , introduced a GPIB interface specification , as well as radio communication analyzer based on GPIB interface MT8801 computer in the PHS communication system which automatically test technology to achieve programming and modular software development work . The author 's work and to make improvements from design to production test .
