Abstract

The user of a mobile station which is prepared to receive information providing services from unspecified IP (Information Providers) accesses a gateway server and performs a pre-registration procedure (S71). When an IP server has information to provide to users, it constructs the information in the form of electronic mail, appends user attribute data, and sends this to the gateway server (S72). Upon receiving electronic mail with attribute data, the gateway server stores the electronic mail in a third mailbox, makes a comparison of the user attributes, and calls the mobile stations of relevant users (S73). A user who has received a call requests a download of the electronic mail from the gateway server (S74). The gateway server sends electronic mail to the mobile station which made the request (S75, S76).

Claims

1. A transfer device located in a mobile packet communication network (MPN) and interconnecting the MPN with a second, separate network, the transfer device communicating with at least one information provider server via the second network and communicating with a plurality of user terminals via the MPN, the transfer device comprising:

at least one memory; and

a processor in communication with the at least one memory, the processor of the transfer device configured to;

convert communication protocols so that the transfer device being located in the MPN serves as a gateway server to interconnect the MPN with the second network;

register in the at least one memory of the transfer device network addresses of the user terminals and corresponding attributes of users of the user terminals, wherein the registration solely involves the MPN;

receive, from an information provider server, push-type information and attribute information appended to the push-type information, which is received via the second network and subjected to a communication protocol conversion by the transfer device, the attribute information describing attributes of users which are to receive the push-type information;

compare the attribute information from the information provider server with the registered attributes of users;

determine at least one network addresses of the user terminals to send the push-type information to based on comparing the registered attributes of users with the attribute information; and

send a communication start notification signal routing of which solely involves the MPN to make at least one user terminal having the determined network address ready for packet switching with the transfer device before transmitting the push-type information to the at least one user terminal.

2. The transfer device of claim 1, wherein the user attributes are not network addresses for the second network.

3. The transfer device of claim 1, wherein the attributes are outside of context of the second network.

4. The transfer device of claim 1, wherein the attributes are selected from the group consisting of name, sex, postal address, and birthdate.

5. The transfer device of claim 1, wherein comparing comprises determining whether the attribute information from the information provider server matches at least one registered attribute of the user.

6. The transfer device of claim 5, wherein determining whether the attribute information from the information provider server matches at least one registered attribute of the user comprises determining whether the attribute information from the information provider server matches a plurality of registered attributes of the user.

7. The transfer device of claim 1, the processor is further configured to:

register at least one information provider server with the transfer device;

determine whether the information provider server from which the push-type information is received is registered with the transfer device; and

reject the push-type information if the information provider is not registered with the transfer device.

8. The transfer device of claim 7, wherein rejecting comprises disposing of the push-type information.

9. The transfer device of claim 7, wherein registering at least one information provider server with the transfer device comprises registering a network address of the information provider server.

10. The transfer device of claim 9, the processor is further configured to detect a network address of the information provider server which sent the push-type information.

11. The transfer device of claim 10, wherein the network address of the information provider server is received from the information provider server.

12. The transfer device of claim 1, wherein the information provider server in the first network follows a first communication protocol,

wherein the plurality of user terminals is in the second network follows a second communication protocol, and

wherein the transfer device comprises a gateway server converting between the first and second communication protocols.

13. The transfer device of claim 12, wherein the first network comprises an Internet;

wherein the second network comprises a mobile communication network; and

wherein the user terminals comprise mobile terminals.

14. The transfer device of claim 1, the processor is further configured to transmit at least a portion of the push-type information to the determined network addresses.
