Radio communication system, and gateways, radio intelligent terminals and radio communication methods applied thereto
First Claim
1. A communication system which establishes a communication between a radio intelligent terminal and a server via a gateway:
- wherein the gateway is provided with an information notifying means, in response to receiving a gateway exchange instruction while the exchange-original gateway is relaying the communication between the radio intelligent terminal and the server, notifying the radio intelligent terminal of the information necessary for the communication between the radio intelligent terminal and the server via an exchange-destination gateway; and
wherein the radio intelligent terminal is provided with a restart activating means, receiving from the exchange-original gateway the information necessary for the communication with the server via the exchange-destination gateway, and executing the restart sequence for the communication with the exchange-destination gateway while suspending the communication with the exchange-original gateway;
the communication system further comprising an information exchange means, wherein if an incomplete transaction is left after the suspend processing of the communication with the exchange-original gateway, by said information exchange means the exchange-original gateway notifies the exchange-destination gateway of the information of the respondent to a request of the terminal before the restart sequence.

Abstract
The present invention is applied to the case that in a communication system establishing the communication between a radio intelligent terminal and a server via gateway, it is necessary to exchange from a gateway to be used originally to other gateway because of any reason. First, it is arranged in this invention that at receiving a gateway exchange instruction an information notifying means may notify a radio intelligent terminal of the generation of gateway exchange. In case of notifying only the gateway exchange, the above information in addition to the exchange notice can contains information necessary for the communication between the radio intelligent terminal and the server via exchange-destination gateway, for example, the exchange-destination gateway address.

25. A radio intelligent terminal which establishes a communication with a server offering to services via gateway, comprising:
-
a restart activating means, in response to receiving an gateway exchange instruction from an operator while the exchange-original gateway is relaying from the radio intelligent terminal to the server, said means receiving from the exchange-original gateway the information necessary for the communication with the server via exchange-destination gateway together with the exchange notice, and executing the restart sequence for the communication with the exchange-destination gateway while suspending the communication with the exchange-original gateway; wherein, in case that there is a incompatibility in the communication conditions with the exchange-original gateway before and after the information necessary after the exchange is exchanged between the exchange-original gateway and the exchange-destination gateway, the information supplementing the incompatibility is sent to the exchange-destination gateway by the restart sequence.
