  • Patent number: 7941550
    Abstract: A method, system, and computer readable media are provided for managing multiple HTTP cookies that are present in a wireless communication system. When a secure or non-secure HTTP cookie is formed, a time of creation for that HTTP cookie is also created as part of the cookie header. Therefore, when a wireless device makes a subsequent communication to a web based server, the gateway compares the creation time for multiple HTTP cookies that are present, and only forwards the most recently created HTTP cookie to the web based server. This avoids invalidating a session as a result of receiving multiple conflicting HTTP cookies from the same wireless device.

  • Patent number: 7933221
    Abstract: A method and medium are provided for regulating a flow of data traffic that is communicated between a mobile device and a wireless telecommunications network. The method includes performing a data-packet-inspection process on at least a portion of the flow and applying a network policy to a specific wireless telecommunications area based on the results of the inspection. The network policy may be based on the wireless coverage area, the application, or the subscriber from which a data-packet originates. The network policy should also determine the way in which to regulate the flow of data if a policy applies to that particular flow. To enforce the policy, the value of a reverse activity bit may be set in connection with the wireless coverage area so as to regulate the flow of data as dictated by the network policy.

  • Publication number: 20100050255
    Abstract: A method, system, and medium are provided for suppressing a Short Message Service (SMS) induced Denial of Service (DoS) attack on a telecommunications network. A register is updated to include information relevant to SMS messages that are requested to be communicated by way of a wireless telecommunications network. The register includes information of the location where the target devices of SMS messages are located. The register is utilized to detect an SMS induced DoS attack. A trigger is communicated to an SMS router to enable a DoS mode that restricts the communication of SMS messages. In an exemplary embodiment, only those SMS messages identified as part of the DoS attack are restricted.
