Abstract
Abstract A method of transmitting Internet data between a mobile host and a remote host coupled via the Internet and a GSM/GPRS cellular telephone network. A plurality of Internet Quality of Service (QoS) levels are defined, in terms of the guaranteed transmission delay over the Internet, using RSVP. A guaranteed QoS is mapped to a circuit switched transmission mode (HSCSD) of the telephone network while a Controlled Load and a Best Effort QoS are mapped respectively to two different service levels of a packet switched transmission mode (GPRS) of the radio telephone network. Prior to transmitting Internet data, transmission capacity in the Internet is reserved, if necessary, to ensure the allocated QoS level is met. The transmission is then made over the Internet and the telephone network, using the transmission mode in the telephone network which is mapped to the allocated QoS.
