METHODS AND SYSTEMS FOR FACILITATING DECODING OF APPLICATION DEFINED OR PROPRIETARY PROTOCOLS IN LAWFUL INTERCEPTS

摘要

Embodiments include servers, systems, and methods for facilitating lawful interception of communication traffic generated by applications on communication devices and transmitted over wireless communication networks. An application identifier is included in communication traffic identifying the application generating the traffic. When the communication traffic is subject to lawful interception the application identifier may be used to determine an appropriate decode and/or decryption process and keys to decode/decrypt the communication traffic. Obtaining the appropriate decode and/or decryption process and keys based on an application identifier included in the communication may obviate the need for law enforcement servers to determine the appropriate process and keys through trial and error. Including an application identifier in communications may also enable lawful intercepts to be conducted based on particular applications generating the communication traffic.

主权项

1. A method for lawful interception of communication traffic generated by an application on a mobile device transmitted over a wireless communication network, comprising:
receiving communication traffic subject to lawful interception; determining whether the received communication traffic includes an application identifier associated with the application that generated the received communication traffic; using the application identifier to obtain information about the application that generated the received communication traffic; and using the obtained information about the application to process the received communication traffic for use by a law enforcement agency authorized to receive the communication traffic.
