Resource reservation in mobile internet protocol
First Claim
1. Apparatus for transmitting data between first and second Internet hosts coupled via the Internet and a digital radio telephone network, the apparatus comprising:
- allocation means for allocating one of a plurality of predefined Internet Quality of Service (QoS) levels to the transmission, said QoS levels being defined in terms of the transmission delay over the Internet;
reservation means for reserving, if necessary, transmission capacity in the Internet to ensure the allocated QoS level is met;
transmission mode selection means for selecting one of a circuit switched or a packet switched transmission mode for transmitting the data over the radio telephone network, said selection being made on the basis of a mapping which maps at least one of the defined Internet QoS levels to the circuit switched transmission mode and maps the remaining QoS level(s) to the packet switched transmission mode; and
transmission means for transmitting said data over the Internet and said radio telephone network according to said allocated QoS and said selected radio telephone network transmission mode.

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.

3. A method of transmitting data between first and second Internet hosts coupled via the Internet and a digital radio telephone network, wherein one of said first and second hosts is a mobile host wirelessly connected to the radio telephone network, and the radio telephone network is a GSM network, and the packet switched transmission mode is GPRS, the method comprising the steps of:
-
defining a plurality of Internet Quality of Service (QoS) levels in terms of the transmission delay over the Internet;
mapping at least one of the defined Internet QoS levels to a circuit switched transmission mode of the radio telephone network and mapping the remaining QoS level(a) to a packet switched transmission mode of the radio telephone network;
prior to transmitting the data, allocating one of the QoS levels to the transmission and, if necessary, reserving transmission capacity in the Internet to ensure that the allocated QoS level is met; and
transmitting the data over the Internet and the radio telephone network, wherein the step of transmitting the data over the Internet is facilitated using Mobile IP to route data via the chosen transmission mode domain and wherein the transmission over the radio telephone network uses the transmission mode mapped to the allocated QoS level.

4. A method of transmitting data between first and second Internet hosts coupled via the Internet and a digital radio telephone network, the method comprising:
-
defining a plurality of Internet Quality of Service (QoS) levels in terms of the transmission delay over the Internet;
mapping at least one of the defined Internet QoS levels to a circuit switched transmission mode of the radio telephone network and mapping the remaining QoS level(s) to a packet switched transmission mode of the radio telephone network;
prior to transmitting said data, allocating one of said QoS levels to the transmission and, if necessary, reserving transmission capacity in the Internet to ensure the allocated QoS level is met; and
transmitting said data over the Internet and said radio telephone network, wherein the transmission over the radio telephone network uses the transmission mode mapped to the allocated QoS level. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)
