 store the first identification information in the memory; 
 determine that the mobile device has left a wireless range covered by the first stationary device, wherein the mobile device has moved to a wireless range covered by a second stationary device; 
 in response to the determination that the mobile device has left the wireless range covered by the first stationary device, access the memory to retrieve second identification information linked to the first identification information, wherein the second identification information is assigned to the mobile device by the second stationary device; and 
 utilize the retrieved second identification information in a signaling protocol to maintain the communication session with the mobile device. 
   
     
     
         9 . The first stationary device of  claim 8 , wherein the operation to determine that the mobile device has left the wireless range covered by the first stationary device includes an operation to:
 receive a signal that indicates that the mobile device has left the wireless range covered by the first stationary device.   
     
     
         10 . The first stationary device of  claim 9 , wherein the signal further indicates that the mobile device has moved to the wireless range covered by the second stationary device. 
     
     
         11 . The first stationary device of  claim 8 , wherein the wireless range covered by the first stationary device and the wireless range covered by the second stationary device are mutually exclusive. 
     
     
         12 . The first stationary device of  claim 8 , wherein the first stationary device is part of a base station or a switch center. 
     
     
         13 . The first stationary device of  claim 8 , wherein the first identification information includes a home internet protocol (IP) address, and wherein the second identification information includes a guest IP address of the mobile device. 
     
     
         14 . A non-transitory computer-readable medium having executable instructions stored thereon that, in response to execution by one or more processors of a first computing device, cause the one or more processors to perform or control performance of operations that include:
 assign first identification information to a mobile device, wherein the first computing device and the mobile device are in the communication session;   store the first identification information in a database;   determine that the mobile device has left a wireless range covered by the first computing device, wherein the mobile device has moved to a wireless range covered by a second computing device;   send a request to access the database to retrieve second identification information linked to the first identification information, wherein the second identification information is assigned to the mobile device by the second computing device;   obtain the second identification information from the database; and   utilize the obtained second identification information in a signaling protocol to maintain the communication session with the mobile device.
