1. One or more computer-readable storage media having computer-executable instructions embodied thereon that, when executed by a computing device, cause the computing device to perform a method of avoiding unnecessary traffic in a wireless communications network, the method comprising:
connecting a first mobile device having a first Network Access Identifier (NAI) to a wireless communications network; assigning a first Internet Protocol (IP) address to the first mobile device; initiating a first user session associated with the first IP address; at an Internet gateway, receiving a request for at least one data packet from the first mobile device; communicating the request for the at least one data packet to a first server; receiving the at least one data packet from the first server; maintaining an unnecessary traffic avoidance table at the Internet gateway that includes a mapping of, at least, the first IP address, an NAI corresponding to a mobile device that is currently associated with the first IP address, an open traffic flow, and an open traffic flow time stamp associated with a request for data of the open traffic flow; determining that the first mobile device is disconnected from the wireless communications network if the unnecessary traffic avoidance table indicates, based on the NAI mapped to the first IP address, that a second mobile device is currently associated with the first IP address; upon determining that the first mobile device is disconnected from the wireless communications network, discarding the at least one data packet from the Internet gateway and terminating the first user session associated with the first IP address; and utilizing the mapped time stamp and the mapped open traffic flow, determining the received at least one data packet was not requested by the second mobile device and should not be billed to the second mobile device. |
