A travel information distribution system includes a distribution center and a wireless terminal of a user who can readily obtaining necessary travel information in traveling places using the wireless terminal such a portable telephone or a portable personal computer. The user visits a travel agency to apply a travel, has a travel schedule table prepared and registers a telephone number of the wireless terminal in a database. The travel agency sends the data of the user to the distribution center, and distribution center receives travel information from information providers. After the departure of the travel, the distribution center transmits necessary travel information to the user at a proper time in a proper place. The user can obtain the necessary updated information in the necessary place and can be free from a heavy weight travel guidebooks. The distribution center can obtain advertisement incomes from travel agencies and advertisement firms.

A game database storing a game program as pay data, a distribution server, and an account server are provided within a service provider side device. The account server sends, through a radio network, a part of a game program to a storage unit in a service user side device, before the arrival of the fixed time of the start of use. When the user has decided to purchase the game program on or after the day on which the data becomes usable, the program part is sent to a game terminal so that the play of the game can be started. Upon the receipt of a request from the user for the distribution of the remaining part of the program, the user's balance is checked for the purchase of the remaining part of the program and, thereafter, the remaining part of the program is sent from the distribution server to the radio terminal so that the user can enjoy the subsequent part of the game without delay. The above construction can shorten the time period between the request for the distribution of data and the reproduction of the distributed data in predetermined communication environment such as radio data communication environment, and can reduce the concentration of load on the distribution server. Further, the invention can also be applied to distribution data for which the limitation of the time of the start of use is not provided.

Data distribution system

When going to a destination, a user of a mobile telephone set stores data distribution plan information in a distribution center via a base station. In the distribution center, an error data for arrival time at the destination is calculated, and is stored in a data distribution plan information storage section. The data distribution plan information storage section subtracts an error time period, after which arrival will be earlier, and generates data distribution plan information. A data transmitting section sets a difference between the current time and distribution scheduled time in a timer circuit, and when time has come, transmits a distribution data stored in a distribution data storage section to the mobile type telephone set.

In an electronic settlement system, a local link is established between a sales terminal and a payee terminal. The sales terminal transmits settlement information including payment data to the payee terminal, and establishes a first communication channel to a settlement center in response to receipt of a payee-terminal identifier identifying the payee terminal and transmits a first signal containing the settlement information and the identifier to the settlement center. The payee terminal transmits the payee-terminal identifier to the sales terminal when a password is entered thereto after the payee terminal has received the settlement information, establishes a second communication channel to the settlement center and transmits the password and a second signal containing the settlement information and the payee-terminal identifier to the settlement center. The settlement center performs a settlement process if the password is a registered password and the first and second signals are identical to each other.

Electronic settlement system using separate communication channels for settlement between sales and payee terminals

An electronic mail system for efficiently transmitting mail data according to a change of the transmission condition of the wireless transmission path is disclosed. The system comprises a mail sender including a mail receiving unit, storage device, mail sending unit, command interpreting section, and mail order rearranging section, and a mail receiver including a mail receiving unit, a receiving condition monitoring section, and a command issuing section. The mail receiving unit monitors the condition of receiving mail data at predetermined intervals, and generates a detection signal when the receiving condition changes. According to the detection signal, the mail receiver sends a command ordering the rearrangement of the mail data. The mail sender receives the command, and rearranges the mail data stored in the storage device.

In data communication utilizing a radio transmission channel, even in a case where the radio channel is disconnected and a data communication blackout occurs, the center side continues data communication processing, by obtaining information on a period where the data communication is interrupted in advance. The system comprises an application server provided in the center, a radio data communication terminal that performs data communication while moving, a mobile gateway provided in the center as a relay device between the application server and the radio data communication terminal, and a period notification device that transmits period information T at predetermined periods. The radio communication channel is disconnected by the period information transmitted from the period notification device, and the mobile gateway performs communication processing during the radio communication disconnection.

Radio data communication technique for maintaining a connection between a mobile radio transmission device and a server during a communication interruption

A communication system of a network includes a server having a table in which clients and telephone numbers are stored in a paired relationship in advance, and the server refers to the table to originate a telephone call to an object client who, upon receiving a data information request, accesses the server. After the information data request is confirmed and the client disconnects a modem line temporarily, the client then originates a telephone call to the server to access the server and to accept communication data from the server.

Communication system for selectively connecting a server to numerous terminal units over a public network

A communication method for a wireless transmission network having a plurality of terminals and a central server, disclosed in the context of an E-mail system. The source terminal sends only a mail header identifying the message source, the destination and other attribute information to the server. The destination terminal receives the digital data directly from the source terminal when desired after first downloading the mail header from the server. Thus, a data recipient can reduce unnecessary communication cost and storage resources in the server and in the system, can be saved.
