融合地址簿系统的反向搜索实现技术

Implementation Technology of Reverse Search for Converged Address Book

为了克服多业务使用多个地址簿带来的诸多麻烦,有必要为用户提供一种统一的平台来管理多个业务的地址簿,开放移动联盟(OMA)提出了融合地址簿系统(CAB),能够保持多终端的地址簿同步更新以及方便用户搜索、共享及订阅联系人信息。其中反向搜索是为了克服搜索双方信息不对称,便于被搜索方进行联系人管理而提出的。文中给出了反向搜索在系统中的结构,对实现反向搜索的关键技术SIP消息方法做了分析,提出了具体的实现流程及软件结构。原型系统的实现结果表明整个实现反向搜索的方法是正确有效的。

In order to conveniently manage diverse address books in multi-services environment,a unified management platform for various kinds of contact information is required.Open Mobile Alliance（OMA） proposed the Converged Address Book（CAB） enabler,which can keep address book synchronous and contact information up-to-date for multiple devices and facilitate the search,share and subscription of contact information.Reverse search is proposed to tackle the problem of asymmetric contact information acquisition of searching and searched users and ease the management of contact information for searched users.In this paper,the functional structure of reverse search is designed.The implementation message sequence and software structure are provided following a brief analysis of SIP message method.The resulting prototype system has proved that the proposed technique for the reverse search is correct and effective.
