In a communication system for establishing the communication between a radio intelligent terminal and a server via gateways, it is necessary to notify a non-communicating and a disconnecting radio intelligent terminal of an address of an exchange-destination gateway at the time of changing from a gateway to be used at all time to an exchange-destination gateway for some reason. To achieve the above object, a communication system comprises address notifying means for notifying the radio intelligent terminal of the address of the exchange-destination gateway according to a gateway exchange instruction inputted by an operation. The address notice is sent to the non-communicating terminal at the time of inputting the gateway exchange instruction, and is sent to the disconnecting terminal when it can start the communication.

What is claimed is: 1. A recording medium storing a program for providing to a radio-based intelligent terminal having a memory for storing an address of a gateway, said address of the gateway being used for communication between the radio-based intelligent terminal and a server offering services via the gateway, an address of an exchange-destination gateway, when an operator inputs the gateway exchange instruction at the time a session is not established between the radio-based intelligent terminal and the gateway. 2. A recording medium storing a program for providing to a radio-based intelligent terminal having a memory for storing an address of a gateway, said address of the gateway being used for communication between the radio-based intelligent terminal and a server offering services via the gateway, an address of an exchange-destination gateway, when a request is received from the radio-based intelligent terminal after an operator inputs the gateway exchange instruction at the time the radio-based intelligent terminal is in a disconnecting state. 3. A radio-based intelligent terminal, comprising: a memory for storing an address of a gateway, said gateway relaying communication between the radio-based intelligent terminal and a server offering services to the radio-based intelligent terminal; a receiving unit configured to receive an address of an exchange-destination gateway; and an address changing unit configured to change the address in the memory to the received address. 4. A radio-based intelligent terminal according to claim 3, wherein a terminal user is notified about the changing of the address when the terminal user starts up the radio-based intelligent terminal. 5. A radio-based intelligent terminal according to claim 3, wherein said receiving unit, in response to a connection request from the gateway, sends a connection confirmation to the address to establish a logical connection between the radio-based intelligent terminal and the gateway, said logical connection being used for transferring the address of the exchange-destination gateway. 6. A radio-based intelligent terminal according to claim 5, wherein said receiving unit, in response to a disconnection request from the gateway after receiving the address of the exchange-destination gateway, sends a disconnection confirmation to stop the gateway. 7. A radio-based intelligent terminal according to claim 3, wherein said address changing unit changes the address in the memory when the user starts up the radio-based intelligent terminal. 8. A radio-based intelligent terminal according to claim 3, wherein said receiving unit, in response to the user starting up the radio-based intelligent terminal, sends a request to the address in the memory. 9. A radio-based intelligent terminal, comprising: a memory for storing an address of a gateway, said gateway relaying communication between the radio-based intelligent terminal and a server offering services to the radio-based intelligent terminal; a receiving unit configured to receive from the gateway an address of an exchange-destination gateway; and an address changing unit configured to change the address in the memory to the received address. 10. A radio-based intelligent terminal according to claim 9, wherein a terminal user is notified about the changing of the address when the terminal user starts up the radio-based intelligent terminal.
