The method may further include mapping a first identifier for the mobile device to the second identifier for the mobile device; and using the second identifier to perform the querying. In certain embodiments, the mapping is initiated responsive to a call received for the mobile device. ## Claims ### Claim 1 A method, comprising: querying by a network device of a first communications network a database maintained by a second communications network for historical location data comprising multiple points along a path typically traversed by a mobile device; using the location data to identify network elements of the first communications network located proximate the path; and sending a page request for the mobile device only to the identified network elements; wherein the first communications network is a cellular communications network and the network elements comprise Home Node Bs (“HNBs”); and wherein the second communications network is a Wireless Local Area Network (“WLAN”). ### Claim 2 (depends on 1) The method of claim 1, further comprising: mapping a first identifier for the mobile device to a second identifier for the mobile device; and using the second identifier to perform the querying. ### Claim 3 (depends on 2) The method of claim 2 wherein the mapping is initiated responsive to a call received for the mobile device. ### Claim 4 (depends on 2) The method of claim 2, wherein the first identifier is a MAC address of the mobile device. ### Claim 5 (depends on 2) The method of claim 2, wherein the second identifier is at least one of an International Mobile Subscriber Identity (“IMSI”) of the mobile device and a Universally Unique Identity (“UUID”) of the mobile device. ### Claim 6 (depends on 1) The method of claim 1, wherein the network device is an HNB Gateway (“HNB-GW”). ### Claim 7 (depends on 1) The method of claim 1, wherein the database comprises a location analytics database. ### Claim 8 One or more non-transitory tangible media that includes code for execution and when executed by a processor is operable to perform operations comprising: querying by a network device of a first communications network a database maintained by a second communications network for historical location data comprising multiple points along a path typically traversed by a mobile device; using the location data to identify network elements of the first communications network located proximate the path; and sending a page request for the mobile device only to the identified network elements; wherein the first communications network is a cellular communications network and the network elements comprise Home Node Bs (“HNBs”); and wherein the second communications network is a Wireless Local Area Network (“WLAN”). ### Claim 9 (depends on 8) The media of claim 8, wherein the operations further comprise: mapping a first identifier for the mobile device to a second identifier for the mobile device; and using the second identifier to perform the querying. ### Claim 10 (depends on 9) The media of claim 9 wherein the mapping is initiated responsive to a call received for the mobile device. ### Claim 11 (depends on 8) The media of claim 8, wherein the network device is an HNB Gateway (“HNB-GW”). ### Claim 12 An apparatus comprising: a memory element configured to store data; a processor operable to execute instructions associated with the data; and a mapping and paging module disposed in a first communications network configured to: query by a first communications network a database maintained by a second communications network for historical location data comprising multiple points along a path typically traversed by a mobile device; use the location data to identify network elements of the first communications network located proximate the path; and send a page request for the mobile device only to the identified network elements; wherein the first communications network is a cellular communications network and the network elements comprise Home Node Bs (“HNBs”); and wherein the second communications network is a Wireless Local Area Network (“WLAN”). ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the mapping and paging module is further configured to: map a first identifier for the mobile device to a second identifier for the mobile device; and use the second identifier to perform the querying. ### Claim 14 (depends on 13) The apparatus of claim 13 wherein the mapping is initiated responsive to a call received for the mobile device. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the first identifier is a MAC address of the mobile device and the second identifier is at least one of an International Mobile Subscriber Identity (“IMSI”) of the mobile device and a Universally Unique Identity (“UUID”) of the mobile device. ### Claim 16 (depends on 12) The apparatus of claim 12, wherein the database comprises a location analytics database. ### Claim 17 (depends on 12) The apparatus of claim 12, wherein the mapping and paging module comprises an HNB Gateway (“HNB-GW”).
