METHOD AND APPARATUS FOR DELIVERING ASSISTANCE DATA FROM A SERVER TO A DEVICE IDENTIFYING VIRTUAL ACCESS POINTS

摘要

Methods and apparatus for processing positioning assistance data are provided. An exemplary method includes receiving, from a positioning server, virtual access point (VAP) data including a list of unique identifiers, and determining a location of a mobile device by using the VAP. The VAP data indicates that the unique identifiers included on the list identify signals originating from the same physical access point. The unique identifiers can be MAC addresses. In an example, the location determining the can include actively scanning a signal identified by a unique identifier on the list and not actively scanning a different signal identified by a different unique identifier also on the list. Not scanning the other MAC addresses that are on the access point's list and assigned to the mobile device keeps the mobile device from performing duplicative scanning that wastes time, processor cycles, and energy.

1. A method for processing position assistance data by a mobile device, comprising:
receiving virtual access point (VAP) data including a list of unique identifiers from a positioning server, the VAP data indicating that the unique identifiers included on the list identify signals originating from the same physical access point (AP); and determining a location of the mobile device, wherein the mobile device uses the VAP data when determining the location.
