Abstract

A method and a device for controlling service transmission can implement service forwarding. The method includes: receiving a connection request message, where the connection request message includes user information; determining value-added service system VAS information according to the user information; receiving a first data packet of the service that is sent by a sending end; obtaining, according to the VAS information, a second data packet from the at least one destination VAS; and sending the second data packet to a receiving end. A VAS performs value-added processing on a data packet, and returns the data packet to a gateway device, allowing the gateway device to perform service arrangement flexibly according to dynamic information about a user.

First claim

What is claimed is:

1. A method for controlling service transmission, comprising:
receiving, by a gateway device, a service request message sent by a user equipment, wherein the service request message comprises user information of the user equipment;
determining, according to the user information, value-added service system (VAS) information indicating at least one destination VAS for value-added processing of a service;
receiving, by the gateway device, a first data packet of the service that is sent to the user equipment by a sending end;
sending, by the gateway device, the first date packet of the service to the at least one destination VAS according to the VAS information;
obtaining, by the gateway device, a second data packet from the at least one destination VAS, wherein the second data packet is a data packet obtained after the at least one destination VAS performs the value-added processing on the first data packet; and
sending, by the gateway device, the second data packet to the user equipment.

2. The method according to claim 1 , further comprising:
obtaining status information that indicates a service status of the service; and
wherein the VAS information is determined according to the user information and the status information.

3. The method according to claim 2 , wherein obtaining the status information that indicates the service status of the service comprises obtaining first status information that indicates an initial service status of the service and the VAS information is determined according to the user information, the status information and first VAS information; and
the method further comprises:
determining that the initial service status changes;
obtaining second status information that indicates the changed initiated service status of the service; and
further determining the VAS information according to the user information by determining second VAS information.

4. The method according to claim 2 , wherein the status information comprises at least one of the following:
(a) time information indicating a current time of the service, and
(b) bearer information indicating a current bearer network of the service.

5. The method according to claim 1 , wherein the VAS information indicates at least two destination VASs of the service; and
the obtaining a second data packet from the at least one destination VAS according to the VAS information comprises:
sending, according to the VAS information, the first data packet to a first destination VAS;
receiving a third data packet sent by the first destination VAS, wherein the third data packet is a data packet obtained after the first destination VAS performs the value-added processing on the first data packet;
sending, according to the VAS information, the third data packet to a second destination VAS; and
receiving a data packet that is sent by the second destination VAS, and obtained after the second destination VAS performs the value-added processing on the third data packet; wherein
the data packet obtained after the second destination VAS performs value-added processing on the third data packet is the second data packet; or
the data packet obtained after the second destination VAS performs the value-added processing on the third data packet is sent to at least another one destination VAS as the second data packet, to enable the at least another one destination VAS to perform the value-added processing again on the data packet obtained after the second destination VAS performs the value-added processing on the third data packet, and to use the data packet obtained after the at least one another destination VAS performs the value-added processing again on the data packet, which is obtained after the second destination VAS performs the value-added processing on the third data packet.

6. The method according to claim 5 , further comprising:
determining priority information that is used to indicate a sequence for sending a data packet in the at least two VASs; and
the obtaining the second data packet from the at least one destination VAS according to the VAS information comprises:
obtaining, according to the VAS information and the priority information, the second data packet from the at least one destination VAS.

7. The method according to claim 1 , wherein the determining the VAS information according to the user information comprises:
sending a first policy request message that comprises the user information to a policy decision server;
receiving a first policy request answer message that comprises first control information and is sent by the policy decision server, wherein the first control information is determined by the policy decision server according to the user information and indicates the VAS information; and
implementing at least one of the following:
(a) determining the VAS information according to a VAS information indication identifier comprised in the first control information; and
(b) obtaining the VAS information from the control information.

8. The method according to claim 2 , wherein the determining the VAS information according to the user information and the status information comprises:
sending a second policy request message that comprises the user information and the status information to a policy decision server;
receiving a second policy request answer message that comprises second control information and is sent by the policy decision server, wherein the second control information is determined by the policy decision server according to the user information and the status information and is used to indicate the VAS information; and
implementing at least one of the following:
(a) determining the VAS information according to a VAS information indication identifier comprised in the first control information; and
(b) obtaining the VAS information from the second control information.

9. An apparatus for controlling service transmission, comprising a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions including a plurality of units, the units including:
a receiving unit, configured to:
receive a service request message sent by a user equipment wherein the service request message comprises user information of the user equipment;
a determining unit, configured to determine value-added service system VAS information according to the user information, wherein the VAS information indicates at least one destination VAS for value-added processing of the service;
the receiving unit, configured to further configured to receive a first data packet of the service that is sent by a sending end to the user equipment;
a sending unit, configured to send the first date packet of the service to the at least one destination VAS according to the VAS information;
an obtaining unit, configured to obtain a second data packet from the at least one destination VAS according to the VAS information, wherein the second data packet is a data packet obtained after the at least one destination VAS performs the value-added processing on the first data packet; and
the sending unit further configured to
send the second data packet to the user equipment.

10. The apparatus according to claim 9 , wherein the determining unit is further configured to:
obtain status information that indicates a service status of the service; and
determine the VAS information according to the user information and the status information.

11. The apparatus according to claim 9 , wherein the determining unit is further configured to:
obtain first status information that indicates an initial service stat
