Abstract

Embodiments provide a policy formulating method. The method includes: receiving, by a policy server, User-Agent information sent by a gateway, where the User-Agent information carries type information of a terminal or type information of a browser used by a terminal; determining, by the policy server, a type of the terminal according to the User-Agent information; and formulating, by the policy server, a charging policy and/or a QoS quality of service policy according to the type of the terminal. Type information of a user terminal or type information a browser used by a terminal is reported to a policy server. The policy server is capable of correctly distinguishing a terminal type, for example a mobile phone or a PC is surfing the Internet, and then the policy server formulates a corresponding policy to implement Internet access charging and QoS guarantee.

Claims

1. A method, comprising:

transmitting, by a gateway, user agent information, wherein the user agent information carries a terminal type information or a browser type information used by a terminal accessing a wireless network;

receiving, by a policy server, the user agent information from the gateway;

determining, by the policy server, whether the terminal is a mobile phone directly accessing the wireless network or a personal computer using a mobile phone as a modem to indirectly access the wireless network according to the user agent information; and

formulating, by the policy server, a charging or quality of service (QoS) policy according to whether the terminal is a mobile phone directly accessing the wireless network or is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

2. The method according to claim 1, further comprising:

registering, by the policy server, a user agent information reporting event on the gateway.

3. The method according to claim 2, wherein after receiving, by the policy server, the user agent information, the method further comprises:

canceling, by the policy server, the user agent information reporting event on the gateway.

4. The method according to claim 2, wherein transmitting, by the gateway, the user agent information comprises:

transmitting, by the gateway, the user agent information in response to the user agent information reporting event.

5. The method according to claim 1, wherein a different charging or QoS policy is formulated when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

6. The method according to claim 1, wherein the charging or QoS policy prohibits the terminal from accessing the Internet when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network, and the charging or QoS policy permits the terminal to access the Internet when the terminal is a mobile phone directly accessing the Internet.

7. The method according to claim 1, wherein the charging or QoS policy provides a different QoS guarantee for the terminal when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

8. The method according to claim 1, wherein the charging or QoS policy specifies a different Internet access charge for the terminal when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

9. The method according to claim 1, wherein the policy server is a policy and charging rules function (PCRF) entity.

10. The method according to claim 1, wherein the gateway is a gateway general packet radio service (GPRS) support node (GGSN).

11. A system, comprising:

a gateway, configured to transmit user agent information, wherein the user agent information carries a terminal type information or a browser type information used by a terminal accessing a wireless network; and

a policy server, configured to;

receive the user agent information from the gateway, wherein the user agent information carries a terminal type information or a browser type information associated with a terminal accessing a wireless network;

determine whether the terminal is a mobile phone directly accessing the wireless network or a personal computer using a mobile phone as a modem to indirectly access the wireless network according to the user agent information; and

formulate a charging or a quality of service (QoS) policy according to whether the terminal is a mobile phone directly accessing the wireless network or a personal computer using a mobile phone as a modem to indirectly access the wireless network.

19. The system according to claim 11, wherein the policy server is a policy and charging rules function (PCRF) entity.

20. The system according to claim 11, wherein the gateway is a gateway general packet radio service (GPRS) support node (GGSN).

12. The system according to claim ii, wherein the policy server is further configured to register a user agent information reporting event on the gateway.

13. The system according to claim 12, wherein the policy server is further configured to cancel the user agent information reporting event on the gateway after the user agent information sent by the gateway is received.

14. The system according to claim 12, wherein the gateway is configured to transmit the user agent information in response to the user agent information reporting event.

15. The system according to claim ii, wherein a different charging or QoS policy is formulated when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

16. The system according to claim ii, wherein the charging or QoS policy prohibits the terminal from accessing the Internet when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network, and the charging or QoS policy permits the terminal to access the Internet when the terminal is a mobile phone directly accessing the Internet.

17. The system according to claim ii, wherein the charging or QoS policy provides a different QoS guarantee for the terminal when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.

18. The system according to claim ii, wherein the charging or QoS policy specifies a different Internet access charge for the terminal when the terminal is a mobile phone directly accessing the wireless network than when the terminal is a personal computer using a mobile phone as a modem to indirectly access the wireless network.
