Methods and apparatus for processing radio modem commands during network data sessions |
摘要 |
A radio modem method of processing commands from a host device during a data communication session between the host device and a server connected to the network includes the steps of maintaining a Point-to-Point Protocol (PPP) connection between the host device and the radio modem device; communicating, over a wireless link with a cellular telecommunications network, data packets of an IP connection maintained between the host device and the server; and while the PPP and the IP connections are being maintained: removing a PPP wrapper of the data packets to reveal a destination IP address; identifying whether the destination IP address matches an IP address of a radio modem server of the radio modem device; in response to identifying a match between the IP addresses, causing the data packets to be routed to the radio modem server and processing and responding to the host device in accordance with a command in the data packets at the radio modem server; and in response to identifying a mismatch between the IP addresses, causing the data packets to be routed to the server over the wireless link with the cellular telecommunications network.
