Abstract

A method for processing subscription service is provided by an embodiment of the invention adapted to establish a connection with a terminal for subscribing to a service through a network, where the terminal is a wireless terminal or a fixed wired network terminal. The method comprises the following steps: receiving from a terminal a subscription service request, which includes a service field; determining whether the subscription service request is legal, according to the service field; and forwarding the subscription service request if the subscription service request is legal. Meanwhile, an embodiment of the invention provides a system for processing subscription service and a gateway device. The embodiment of the invention makes it possible to prevent any terminal from accessing the network through the gateway device, which eliminates the potential hazard in the subscription system. Meanwhile, according to the embodiment of the invention, illegal terminals can not access the subscription network, which refines the subscription network and improves the stability of the subscription network.

Claims

1. A method for processing subscription service, comprising:

receiving from a terminal a subscription service request, which includes a service field;

determining whether the subscription service request is legal, according to the service field; and

forwarding the subscription service request if the subscription service request is legal.

2. The method for processing subscription service of claim 1, wherein the step of forwarding the subscription service request further comprises:

performing subscription protocol translation and transmitting the subscription service request using the translated protocol.

3. The method for processing subscription service of claim 1, wherein the method further comprises:

transmitting a connection reject signal to the terminal if the subscription service request is illegal.

4. The method for processing subscription service of any of claim 1, wherein the method further comprises:

disconnecting the connection with the terminal if the subscription service request is illegal.

5. The method for processing subscription service of claim 2, wherein the terminal is a handset, the subscription service is a Wireless Application Protocol (WAP) subscription service, the subscription protocol translation is a protocol translation performed between the WAP and a Hyper Text Transfer Protocol (HTTP).

6. The method for processing subscription service of claim 1, wherein the method further comprises:

forwarding to the terminal a subscription request reply to indicate to the terminal user that the subscription service connection is successful.

7. The method for processing subscription service of claim 1, wherein the step of determining whether the subscription service request is legal comprises:

searching a legal field library stored at a gateway device according to the service field in the subscription service request to make the determination;

if the service field is found, the subscription service request is legal;

if the field is not found, the subscription service request is illegal.

8. A system for processing subscription service, comprising:

a subscription platform server, adapted to process subscription service from a terminal user; and

a gateway device, adapted to receive a subscription service request from the terminal and determine whether the subscription request from the terminal is legal according to the subscription service request; and

forward the subscription service request to the subscription platform server when the subscription service request is legal.

9. The system for processing subscription service of claim 8, wherein the gateway device searches a legal field library stored at the gateway device according to the service field in the subscription service request to determine whether the subscription service request from the terminal is legal;

and if the service field is found, the subscription service request is legal.

10. A gateway device comprising:

a receiving unit, adapted to receive a subscription service request from a terminal;

a subscription request determining unit, adapted to determine whether the subscription service request from the terminal is legal according to the subscription service request; and

a forwarding unit, adapted to forward the subscription service request.

11. The gateway device of claim 10, wherein the gateway device further comprises:

a protocol translation unit, adapted to translate communication protocols between the terminal and a subscription platform server.

12. The gateway device of claim 10, wherein the gateway device further comprises:

a connection-refused prompt unit adapted to transmit a connection-refused signal to the terminal.

13. The gateway device of claim 10, wherein the forwarding unit is further adapted to reply to the subscription request, the subscription request reply indicates to the terminal user that the subscription service connection is successful.

14. The gateway device of claim 11, wherein the gateway device further comprises:

a protocol translation control unit, adapted to control whether the protocol translation unit should perform protocol translation.

15. The gateway device of claim 10, wherein the gateway device further comprises:

a storage unit, adapted to store a legal field library;

a field searching unit, adapted to search the legal field library according to a service field in the subscription service request;

the subscription request determining unit determines whether the subscription service request is legal according to the search result of the field searching unit;

if the service field is found, the subscription service request is legal;

if the field is not found, the subscription service request is illegal.
