摘　　要：对当今世界主流的基于信令中继的移动号码携带(MNP)短消息服务解决方案进行了分析,并针对其不足提出了一种新的MNP短消息服务解决方案。通过在发端网络中引入集成了查询功能的虚拟节点,在基本不改造原有网络情况下实现了MNP功能,虚拟节点在网络中充当功能互不相同的实体网元。分析表明,该方案在网络改造成本和可实施性方面优于基于信令中继的解决方案,从而更适合中国的移动通信网络环境。The solution of short message service （SMS） for mobile number portability （MNP） based on signal relay foundation successfully implemented in many countries and areas is analysed. In order to cover its shortcomings, a novel solution to SMS for MNP is proposed. Query - integrated virtual nodes serving as different entities are introduced into the originating network to achieve the MNP function without changing original network greatly. Analysis results show that this solution is superior to the previous solution in cost of network transformation and implementation. As a result,it is more suitable to the mobile communication network in china.
