Methods, systems, and devices for determining a closest base station to a multi-mode mobile device

An apparatus for determining a closest base station to a multi-mode mobile device, the system comprising:

• a means for determining a plurality of propagation delays with respect to a common reference time between the multi-mode mobile device and each of a first plurality of base stations, wherein each of the first plurality of base stations is associated with a different wireless communications technology from a plurality of wireless communications technologies;
• a means for comparing the plurality of propagation delays between the multi-mode mobile device and the first plurality of base stations associated with the different wireless communications technologies;
• and
• a means for identifying a closest base station to the multi-mode mobile device from the first plurality of base stations based on the comparison.
