Abstract
Abstract Data to be transmitted from an information source (301), associated with a local/wide area network (303), to a target destination (317) is formatted into a plurality of data packets. Based on a message type of the data packets, either a circuit-switched network (311) or a packet-switched network (309) is selected. When the circuit-switched network is chosen, a circuit-switched channel (314) is established to the target destination, and the data packets are transmitted to the target destination via the circuit-switched channel. When the packet-switched network is chosen, a packet-switched channel (313) is established to the target destination, and the data packets are transmitted to the target destination via the packet-switched channel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A method comprising the steps of: providing information to be transmitted, which information comprises one message type of a plurality of message types as indicated by a TCP session header included in the information; formatting the information into a plurality of data packets; automatically selecting as between a circuit switched network and a packet switched network based on the one message type indicated by the TCP session header, wherein the circuit switched network is selected when a long type is indicated by the one message type, and wherein the packet switched network is selected when a short type is indicated by the one message type; when the circuit switched network is selected, establishing a circuit switched channel and transmitting the plurality of data packets via the circuit switched channel; when the packet switched network is selected, establishing a packet switched channel and transmitting the plurality of data packets via the packet switched channel.
Claim 2
Independent Claim
153 words
A method comprising the steps of: providing information to be transmitted, which information comprises one message type of a plurality of message types as indicated by a TCP session header included in the information; formatting the information into a plurality of data packets; automatically selecting as between a circuit switched network and a packet switched network based on the one message type indicated by the TCP session header, wherein the circuit switched network is selected when a long type is indicated by the one message type, and wherein the packet switched network is selected when a short type is indicated by the one message type; when the circuit switched network is selected, establishing a circuit switched channel and transmitting the plurality of data packets via the circuit switched channel; when the packet switched network is selected, establishing a packet switched channel and transmitting the plurality of data packets via the packet switched channel.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein the step of establishing the circuit switched channel includes the step of establishing an RF-based communication channel as the circuit switched channel.
Claim 4
Dependent Claim
28 words
The method of claim 1 wherein the step of establishing the packet switched channel includes the step of establishing an RF-based communication channel as the packet switched channel.
Claim 5
Independent Claim
245 words
A method for communicating information between a source and at least one destination, the method comprising the steps of: at the source; providing information to be transmitted, which information comprises one message type of a plurality of message types as indicated by a TOP session header included in the information; formatting the information into a plurality of data packets; automatically selecting as between a circuit switched network and a packet switched network based on the one message type indicated by the TCP session header, wherein the circuit switched network is selected when a long type is indicated by the one message type, and wherein the packet switched network is selected when a short type is indicated by the one message type; when the circuit switched network is selected, establishing a circuit switched channel and transmitting the plurality of data packets via the circuit switched channel; when the packet switched network is selected, establishing a packet switched channel and transmitting the plurality of data packets via the packet switched channel; at the at least one destination; determining that the plurality of data packets is being transmitted as between the circuit switched network and the packet switched network; when the plurality of data packets is transmitted over the circuit switched network, receiving the plurality of data packets via the circuit switched channel; and when the plurality of data packets is transmitted over the packet switched network, receiving the plurality of data packets via the packet switched channel.
Claim 6
Independent Claim
245 words
A method for communicating information between a source and at least one destination, the method comprising the steps of: at the source; providing information to be transmitted, which information comprises one message type of a plurality of message types as indicated by a TOP session header included in the information; formatting the information into a plurality of data packets; automatically selecting as between a circuit switched network and a packet switched network based on the one message type indicated by the TCP session header, wherein the circuit switched network is selected when a long type is indicated by the one message type, and wherein the packet switched network is selected when a short type is indicated by the one message type; when the circuit switched network is selected, establishing a circuit switched channel and transmitting the plurality of data packets via the circuit switched channel; when the packet switched network is selected, establishing a packet switched channel and transmitting the plurality of data packets via the packet switched channel; at the at least one destination; determining that the plurality of data packets is being transmitted as between the circuit switched network and the packet switched network; when the plurality of data packets is transmitted over the circuit switched network, receiving the plurality of data packets via the circuit switched channel; and when the plurality of data packets is transmitted over the packet switched network, receiving the plurality of data packets via the packet switched channel.
Claim 7
Dependent Claim
28 words
The method of claim 4 wherein the step of establishing the circuit switched channel includes the step of establishing an RF-based communication channel as the circuit switched channel.
Claim 8
Dependent Claim
28 words
The method of claim 4 wherein the step of establishing the packet switched channel includes the step of establishing an RF-based communication channel as the packet switched channel.
