Abstract:
A method comprising:establishing a PPP connection between a mobile device and a PPP server via an access point, wherein the mobile device is equipped with a serial asynchronous communication interface, the PPP server is attached to a packet switched data network via a packet switched communication interface, and the access point is acting as a bridge between the serial asynchronous communication interface and the packet switched communication interface, by: receiving a PPP connection establishment frame at the access point from the mobile device over the serial asynchronous communication interface; establishing a bi-directional network layer tunnel between the access point and the PPP server over the packet switched data network; forwarding the PPP connection establishment frame to the PPP server over the biderectional network layer tunnel; and maintaining the flow of PPP frames between the PPP server and the device via the access point by forwarding PPP frames received from the mobile device to the PPP server over the bi-directional network layer tunnel, and forwarding the PPP frames received from the PPP server over the bi-directional network layer tunnel to the mobile device over the serial asynchronous communication interface.
