Methods and devices for facilitating location approximation in a CDMA 1x network

An access terminal configured for wireless communication, comprising:

• means for determining to retrieve position information corresponding to the access terminal;
• means for determining system information corresponding to each of a plurality of base stations by receiving a transmission from each of the plurality of base stations, in response to the determining to retrieve position information;
• means for storing the system information corresponding to each of the plurality of base stations, each system information further being stored with a respective time stamp corresponding to a time when the system information is determined;
• means for transmitting the system information corresponding to each of the plurality of base stations and the respective time stamps, for localization of the access terminal;
• and
• means for transmitting accumulated system information corresponding to at least one previous base station, and accumulated timestamps corresponding to the at least one previous base station, the accumulated system information and timestamps gathered over time and stored in the memory as the access terminal moves about an access network comprising the plurality of base stations.

A non-transitory computer readable medium storing computer executable code, comprising instructions for causing an access terminal to:

• determine to retrieve position information corresponding to the access terminal;
• determine system information corresponding to each of a plurality of base stations by receiving a transmission from each of the plurality of base stations, in response to the determining to retrieve position information;
• store in memory the system information corresponding to each of the plurality of base stations, each system information further being stored with a respective time stamp corresponding to a time when the system information is determined;
• transmit the system information corresponding to each of the plurality of base stations and the respective time stamps, for localization of the access terminal;
• and
• transmit accumulated system information corresponding to at least one previous base station, and accumulated timestamps corresponding to the at least one previous base station, the accumulated system information and timestamps gathered over time and stored in the memory as the access terminal moves about an access network comprising the plurality of base stations.

An access terminal configured for wireless communication, comprising:

• a processing circuit;
• a communications interface communicatively coupled to the processing circuit for transmitting and receiving information;
• and
• a memory communicatively coupled to the processing circuit for storing information,
• wherein the processing circuit is configured to:
