Data communication system and method
First Claim
1. A data communication system which sends or receives data to or from an application server using the same protocol via a transmission line comprising one type selected from a group consisting of a wire communication network, a wireless communication network, and both a wire communication network and a wireless communication network, said data communication system comprising:
- a first table containing therein a relation among a service identifier of the application server, a destination address, a communication network type, and processing time of the application server; and
a retransmission timer setting unit which references said first table to acquire the processing time of the application server based on the service identifier, destination address, and communication network type during transmission or reception of data to or from said application server and sets the time as a retransmission time.

Abstract
A data communication system, which sends or receives data to or from an application server using the same protocol via a transmission line as one of a wire communication network, a wireless communication network, and both a wire communication network and a wireless communication network, comprises a table 14 containing therein a relation among a service identifier of the application server, a destination address, a communication network type, and a processing time of the application server; and a retransmission timer setting unit 16 which references the table to obtain the processing time of the application server based on the service identifier, destination address, and communication network type during transmission or reception of data to or from the application server and sets the time as a retransmission time.

3. A data communication system which sends or receives data to or from an application server using the same protocol via a transmission line comprising one type selected from the group consisting of a wire communication network, a wireless communication network, and both a wire communication network and a wireless communication network, said data communication system comprising:
-
(a) a variable-length sending buffer in which data to be sent to the application server is stored;
(b) a table containing therein relation among radio wave strength of the wireless communication network, error rates of data sent to or received from the communication network, communication network types, communication network transmission speeds, and sizes of said sending buffer; and
(c) a buffer size controller which references said table to adjust the size of said sending buffer based on the acquired radio wave strength and the error rate. - View Dependent Claims (4, 6, 8, 11)

12. A data communication system which sends or receives data to or from an application server using the same protocol via a transmission line comprising one type selected from the group consisting of a wire communication network, a wireless communication network, and both a wire communication network and a wireless communication network, said data communication system comprising:
-
(a) a first table containing therein a relation among service identifiers of the application server(s), destination addresses, communication network types, and processing time of the application server;
(b) a retransmission timer setting unit which references said first table to acquire the processing time of the application server based on the service identifier, destination address, and communication network type during transmission or reception of data to or from said application server and sets the time as a retransmission time;
(c) a variable-length sending buffer in which data to be sent to the application server is stored;
(d) a second table containing therein a relation among radio wave strength of the wireless communication network, error rates of data sent to or received from the communication network, the communication network types, and communication network transmission speeds; and
(e) a buffer size controller which references the second table to adjust size of said sending buffer based on the acquired radio wave strength and the error rate.

13. A data communication method for sending or receiving data to or from an application server using the same protocol via a transmission line comprising one type selected from the group consisting of a wire communication network, a wireless communication network, and both a wire communication network and a wireless communication network, said data communication method comprising the steps of:
-
(a) storing relation among service identifiers of the application server, destination addresses, communication network types, and processing time of the application server in a table; and
(b) referencing said table to set the processing time of the application server as a retransmission time based on the service identifier, destination address, and communication network type during transmission or reception of data to or from said application server.
