1. A non-transitory computer-readable medium having stored therein a computer-implemented method comprising:
- receiving from a wireless landmark a message that includes a location indicator generated by the wireless landmark, the location indicator comprising information that corresponds to a current location of a wireless landmark in a mobile communication network, the wireless landmark comprising a mobile device having a telephone that communicates through the mobile communication network;
communicating with the wireless landmark to estimate the location of a first node in the mobile communication network proximate to the wireless landmark with the estimated location of the first node being based on the current location of the wireless landmark, the first node being a fixed location apparatus for routing communications with the mobile device and other mobile devices; and
determining an estimated location of another, different mobile device using the determined location of the first node.

19. A non-transitory computer-readable medium having stored therein a computer-implemented method comprising:
-
obtaining an Internet Protocol (IP) address of a mobile device; obtaining an IP address of a router that serves a geographic region containing the mobile device, based on the IP address of the mobile device; determining a geographic region in which the router is located based on the IP address of the router; and outputting an estimated location of the mobile device based on the geographic region corresponding to the router; wherein determining a geographic region in which the router is located comprises; obtaining network delay values related to the router using location and constraint information of one or more wireless landmarks, the one or more wireless landmarks comprising one or more mobile devices that communicate through the router and include telephones, and translating the network delay values into distance constraints. - View Dependent Claims (20, 21, 22, 23, 24)

25. A system for providing location estimates of network devices, the system comprising:
-
a wireless landmark locator to receive current location information from a wireless landmark and identify a location for the wireless landmark, the wireless landmark comprising a first mobile device having a telephone that communicates through a wireless network; means for determining location information of one or more intermediate network nodes in the wireless network using the location for the wireless landmark with the estimated location of the one or more intermediate network nodes being based on the current location of a wireless landmark, the one or more intermediate network nodes being fixed location apparatuses for routing communications with the wireless landmark and other mobile devices; and a mobile device interface configured to estimate a location for a second mobile device communicating with the system using the location information of the one or more intermediate nodes.
