    Abstract: The function of determination of location is separated from the function of gathering information based on determined location by use of a Location Object (LO) proxy between an initiating VoIP capable device and a positioning center. The LOProxy queries an appropriate location database using a location key, and injects a PIDF-LO into a routing SIP message otherwise without location. A SIP request without location is received from a VoIP capable device. The SIP request contains messages indicating the type of location generator or service needed. A location key (like a telephone number or SIP URI), in addition to the type of location generator or service needed, is included in a SIP request. A location object (LO) broker may be used between a routing SIP message and a positioning center to direct a routing SIP message to an appropriate one of a plurality of location object (LO) proxies.

    Abstract translation: 通过使用位于发起VoIP的设备和定位中心之间的位置对象(LO)代理,基于确定的位置来收集位置信息的功能与收集信息的功能分离。 LOProxy使用位置密钥查询适当的位置数据库,并将PIDF-LO注入路由SIP消息,否则没有位置。 从具有VoIP功能的设备接收到没有位置的SIP请求。 SIP请求包含指示所需位置生成器或服务类型的消息。 除了需要的位置发生器或服务的类型之外,位置密钥(如电话号码或SIP URI)被包括在SIP请求中。 可以在路由SIP消息和定位中心之间使用位置对象(LO)代理,以将路由SIP消息引导到多个位置对象(LO)代理中的适当的一个。
