Research on OSA-Based Solutions in Providing Value-Added SMS
Jianxin Liao · Beijing Youdian Xueyuan xuebao · 2004
Two open service access(OSA)-based solutions providing value-added short message service(SMS)are proposed for mobile telecom in china. The first solution is target-solution, which builds the value-added SMS network directly and exclusively by OSA technology. The second solution is overlay-solution, which integrates the existing proprietary value-added SMS network into OSA architecture. The second one can smoothly migrate to the first one. Applicable cases, technical features and operating modes for each solution are discussed in detail. Meanwhile, a method of the mapping from SMS protocols to OSA application programming interface (API) is forwarded, i.e. OSA gateway triggers the short message from subscriber to service provider (SP) as predefined user interaction (UI) event and report it to SP.
