ABSTRACT:
Mobile station position determination through a wireless communication network, such as a preliminary fix for use in satellite acquisition assistance, utilizes wireless network almanac data defined in a “virtual” manner, for example, with regard to “virtual base stations.” A virtual base station (VBS) is a logical construct, essentially modeled from a number of actual base stations in a generally known region that use some common identification (e.g. the same SID/NID combination). The VBS has a coverage/service area approximating the aggregate coverage area of the actual base stations. The service provider offering acquisition assistance or a location based service need not know the precise locations of the actual base stations. Instead, the service provider can compile a virtual base station almanac (VBSA) based on the identification information and virtual base station location information, for example, to support the service(s) when the provider's customers roam onto another carrier's network facilities.
