Since different methods or protocols have been used to manage various mobile terminals, it has been difficult to manage mobile terminals efficiently. OMA(Open Mobile Alliance), therefore, proposed OMA DM(Device Management) as a standard for device management. In this paper, in an effort to apply the OMA DM concept ta real application area a home-delivery service management system using OMA DM agents is designed and implemented. The home-delivery service management system is developed using SyncML Tool Kit 4.3, SK WIPI SDK and Embedded Visual-C++ under the environment of SK-WIPI Clet. Since the home-delivery service management system is developed using OMA DD which is expected to be installed in most of the mobile terminals, separate lower level program modules for the management system would not be necessary. In order to justify this world some experiments are performed using SK WIPI emulator 1.1., which provides the same execution environments as a real mobile terminals does. Experiments show that the home-delivery service management system developed in this paper, works properly.

With the rapid advancement of mobile communication, mobile devices are evolving into convergence devices with various multimedia capabilities. But, high performance of devices demands complicated settings, and thus contains latent error possibilities, and poor system performance caused by the collision of different softwares. To solve these problems, device management becomes an important issue. Open Mobile Alliance(OMA) developed OMA DM(Device Management), which is a device management standard. Recently released OMA DM v1.2 provides improved mobile device management methods compared to earlier versions. This paper introduces design and implementation of OMA DM v1.2 based management agent. By using Tree and Description Serialization(TNDS) for acquiring, adding, and editing objects in the mobile devices, it provides more effective device management with small amount of network traffic.

There has been a continued increase in the complexity of software equipped with wireless mobile devices, due to the introduction of new device functionality and services via network connection. The increasement expected to be accelerated by convergence of telecommunication and broadcasting, and proliferation of telematics and home networking services using wireless mobile devices. The higher the complexity of mobile device software, the higher the necessity of management for the software. As for the global standard of mobile device management technology, OMA DM has been widely adopted by device manufacture and expected to be accelerated its adoption. In this paper, we present a development result of mobile device software release management system ThinkSync DM SoftMan. The implementation details of ThinkSync DM SoftMan are provided in implementation architecture and its working scenario based on the design of ThinkSync DM SoftMan that is summarized in this paper as our previous work. The conformance and performance test of the system are presented.

Recently, the number of smartphone users is rising rapidly due to an influx of foreign smartphones and sales of domestic products. According to the increase of smartphone users, smartphone malwares are also increasing sharply. Hence it is necessary to protect smartphone against mobile malwares. There are device management protocols as SNMP, TR-069. But these protocols are not suitable for mobile device management because of restrictive management function and unsupported mobility. OMA DM which is a standard for mobile device management has been adopted as mobile device management protocol for most of 2G,3G. Thus it amounts that OMA DM is suitable for smartphone management system. In this paper, the mobile device management system based on OMA DM is designed. This system can remove smartphone malware by remote control.

Mobile devices become more complex and harder to manage due to the advance of technologies. In this paper, we designed and implemented the DM Agent based on OMA(Open Mobile Alliance) DM(Device Management) which is a standard for mobile device management. The proposed DM Agent basically can manage parameter configuration through the commands ADD, DELETE, REPLACE and GET currently. Each module of the agent was designed and implemented separately for additional functions such as error reporting and software management. So the additional functions can be added by modifying Adaptor part which processes the management commands instead of modifying other modules which analyze or generate management commands. The DM Agent proposed in this paper is implemented based on WIPI(Wireless Internet Platform for Interoperability), therefore portability of the agent can be improved. In addition, this research can give a development example for dissenminating OMA DM as well as verify functional compatibility of WIPI platform. SK WIPI SDK and a Funambol DM test server are used to test operations of the implemented DM Agent.

복약기는 개인의 건강 증진 및 질병 예방을 위한 개인건강기기(Personal Health Device: PHD) 중 하나로 정해진 스케줄에 따라 약을 배출하는 기기이다. 복약기를 통해 수집되는 복약자의 복약상태(복약 여부, 복약 횟수 등)는 의료진 및 보호자에게 복약자를 관리하기 위한 중요한 정보가 될 수 있으므로 모니터링 서버에게 실시간 전송하여 의료진 및 보호자가 분석할 수 있도록 하는 것이 바람직하다. 이에 본 논문에서는 복약기 내에 탑재되어 사용자의 복약상태를 원격 모니터링 서버에게 실시간 전송하는 복약상태 전송 에이전트를 제안한다. 복약상태 전송 에이전트는 단말기 관리에 관한 산업계 표준인 Open Mobile Alliance(OMA) Device Management(DM) 프로토콜에 따라 복약 상태 메시지를 생성 및 전송한다. 복약 상태 메시지를 수신하는 모니터링 서버로는 OMA DM 기반의 상용 서버를 사용하였다. 이는 추후 본 논문의 복약상태 전송 에이전트를 확장하여 복약기 원격 관리 용도로 적용하기 위함이다. 본 논문에서는 제안된 복약상태 전송 에이전트의 구현 결과 및 모니터링 서버와 연동성 검증 결과를 제시한다. 검증 결과 제안된 에이전트는 복약기로부터 복약상태를 수집한 후 OMA DM 프로토콜에 따라 복약상태를 정상적으로 전송함을 알 수 있었다. 즉, 본 논문의 복약상태 전송 에이전트는 복약상태의 원격 전송뿐 만 아니라, OMA DM 을 준수하는 기존의 모바일 단말기 관리 서버들을 복약상태 모니터링 서버로 활용할 수 있다는 장점이 있다.

Utilizing smart phones based on android applications in the field of FA(Factory Automation) or PA(Production Automation) is being deployed actively. In general, MDM(Mobile Device Management) is a crucial infra-structure to build such a FA or PA environment. In this paper, we suggest an open mobile device management platform and implement its prototype. The developed prototype consists of three modules such as DMS(Device Management Server), FUMO(Firmware Update Management Object) and SCOMO(Software Component Management Object). In addition, we suggest a security module based on the concept of the EAP (Extensible Authentication Protocol) and the AES (Advanced Encryption Standard). The suggested security module's prototype is applied to guarantee the data integrity in the process of communicating among DMS, FUMO and SCOMO for the purpose of utilizing smart phones based on android applications in a FA field. We also evaluate the performance of the implemented security prototype. According to our simulation results, the implemented prototype has a good performance in a FA environment and can be utilized in the other FA, PA or OA(Office Automation) environment with guaranteeing the security.
