ENCODED WIRELESS DATA DELIVERY IN A WLAN POSITIONING SYSTEM
First Claim
1. A method performed by a mobile device for obtaining information regarding access points in a wireless network, the method comprising:
- transmitting to a server a request for information regarding access points;
in response to the request, receiving encoded access point identification data for a plurality of access points corresponding to the request, the encoded access point identification data comprising;
a reference identifier comprising a number of groups of bits,an encoding mask for an access point identifier, wherein the encoding mask identifies groups of bits for the access point identifier that are identical to corresponding groups of bits for the reference identifier, andgroups of bits of the access point identifier that are not identical to corresponding groups of bits for the reference identifier; and
decoding at least some of the encoded access point identification data.

Abstract
A mobile device transmits to a server a request for information regarding access points in a wireless network. In response to the request, the mobile device receives encoded access point identifiers for a plurality of access points. The encoded access point identifiers include a reference identifier that has a number of groups of bits. The encoded access point identifiers also include encoding masks for respective access point identifiers, wherein a respective encoding mask identifies groups of bits for the respective access point identifier that are identical to corresponding groups of bits for the reference identifier. The encoded access point identifiers further include, for the respective access point identifiers, groups of bits that are not identical to the corresponding groups of bits for the reference identifier. The mobile device decodes at least some of the encoded access point identifiers.
