A technique to gather and assess the quality of a location based services provided to a mobile wireless device via a wireless network includes providing location-based service information by referring to a target location of a requested item of interest within a proximity of the present location of the mobile wireless device. Subjective quality or accuracy information can be submitted to the wireless network from the from the wireless device. The subjective quality or accuracy information is correlated with event and condition information affecting the wireless network. Reports can be generated which indicate the quality and accuracy information of the target location information. The reports are useful for troubleshooting location-based service inaccuracy.

Location based services quality assessment

A geographic cell identification (cell ID) database is updated on the fly as, for example, roaming user equipment (UE) reports its location during Assisted Global Positioning System (A-GPS) operations. The cell ID database relates network locations to corresponding geographic locations. The cell ID database is used to retrieve a corresponding geographic location in response to the network location at which the UE reports being located. If it is found that the cell ID database does not contain the network location reported by the UE, the geographic location of the UE can be estimated using information in the reported network location, such as Mobile Network Code, Mobile Country Code, Local Area Code and Cell ID. The geographic location can then be used to obtain A-GPS assistance data for the UE. Once assistance information has been provided to the UE and the UE has determined its geographic location, the cell ID database can be updated with the determined geographic location.
