A communications network and method is provided for framing point-to-point frame structures to minimize the overhead that consumes the bandwidth of a radio air interface located between a mobile station and a packet switched network. More specifically, the mobile terminal utilizes a serial interface and point-to-point protocol to connect to a data terminal, and a communication protocol and air interface to connect to the packet switched network. The mobile terminal inserts a first predetermined set of fields (overhead) onto a first frame structure (data) received from the packet switched network, and then forwards the inserted first frame structure (data and overhead) to the data terminal equipment. In addition, the mobile terminal removes a second predetermined set of fields (overhead) from a second frame structure (data and overhead) received from the data terminal, and then forwards the stripped second frame structure (data) to the packet switched network. Wherein the consumption of the bandwidth is minimized when the frame structures depending on the direction of travel are either stripped off or inserted with overhead fields such that mostly data is transmitted between the mobile terminal and the packet switched terminal. |
