[Abstract]:Under the condition of no base station communication, ultra-short wave wireless communication technology is widely used in military, disaster relief site and emergency support communication and other scenarios. After the application of ultra-short wave communication in the field of personal communication, ultra-short wave communication equipment is gradually developing towards miniaturization, intelligence and high performance. With the miniaturization and high performance of ultra-short wave communication equipment, small platforms, such as common handheld platforms, can improve the carrying capacity of wireless communication or meet the needs of diversified applications through hardware upgrades, which will lead to a significant increase in power consumption. In order to solve this problem, the intelligent operating system improves the power supply efficiency of the whole platform and prolongs the battery life through a more perfect power management mechanism. However, most of the mature intelligent operating systems are in a closed or semi-open source state, which is not conducive to custom communication protocol stack, and realizes the development and optimization of specific hardware platforms. Therefore, based on the open source characteristics of Android smartphone operating system [1], this paper designs and develops the handheld platform software of ultra-short wave communication on Android operating system, realizes the service of ultra short wave broadband communication service, and has good operation. Maintenance and expansibility. First of all, the overall function of ultra-short wave handheld platform is put forward. The ultra-short wave communication platform realizes short message and digital voice services in function, meets the requirements of data transmission rate and bit error rate in performance, and ensures the communication efficiency and reliability. Secondly, the service management framework of ultra-short wave handheld platform is constructed. The service signaling format and the complete design flow with signaling as the main line from the upper layer to the bottom are defined in detail, and the data access function of the service application layer data and voice module is integrated to effectively support the operation and management of the communication service. Thirdly, the service management and the underlying data transmission module of the ultra-short wave handheld platform are designed and implemented. Based on the system framework and internal running mechanism of Android operating system, the service level and function module are divided, and the concrete implementation mode and process control are given. at the same time, the data transmission mode supporting full duplex communication at the bottom level is given. Finally, the communication service processing ability of ultra-short wave handheld platform software is verified. The upper software, the underlying voice module driver and the overall function are tested respectively, and the BER test results of the whole communication platform are given. Android operating system provides an open source system-level solution for the development and application of wireless communication terminals. In this paper, the development of ultra-short wave communication broadens the wireless function of Android on handheld platform, and completes emergency communication when other networks are not available or unsmooth, which has certain practical value.
