Abstract

The present invention provides a service data transmission processing method and device and a communication system. The service data transmission processing method includes: receiving, by a service offloading apparatus, uplink service data sent by a user equipment; obtaining, by the service offloading apparatus, a service type of the uplink service data; and sending, by the service offloading apparatus, uplink service data, a service type of which is a core network service to a core network service proxy apparatus through a first service tunnel, or sending, by the service offloading apparatus, uplink service data, a service type of which is a non-core network service to a non-core network service proxy apparatus through a second service tunnel. The technical solutions can avoid excessive use of backhaul network resources of a core network by non-core network services.

First claim

What is claimed is:

1. A service data transmission processing method comprising:
when a service offloading apparatus obtains a second instruction from a serving gateway, requesting, by the service offloading apparatus, a non-core network service proxy apparatus to assign an IP address to a user equipment, wherein the second instruction is used for requesting the assigning of the IP address to the user equipment and/or establishment of a second service tunnel between the service offloading apparatus and the non-core network service proxy apparatus for the user equipment;
receiving, by the service offloading apparatus, the IP address which is sent by the non-core network service proxy apparatus and is assigned to the user equipment;
sending the IP address to the user equipment;
receiving, by the service offloading apparatus, uplink service data sent by the user equipment;
obtaining, by the service offloading apparatus, a service type of the uplink service data;
determining whether the service type of the uplink service data obtained by the service offloading apparatus is a core network service or a non-core network service;
if the service type of the uplink service data obtained by the service offloading apparatus is a core network service, sending, by the service offloading apparatus, the uplink service data to a core network service proxy apparatus through a first service tunnel; and
if the service type of the uplink service data obtained by the service offloading apparatus is a non-core network service, sending, by the service offloading apparatus, the uplink service data to a non-core network service proxy apparatus through the second service tunnel.

2. The service data transmission processing method according to claim 1 , wherein
the non-core network service is an external Internet service, and the non-core network service proxy apparatus is a traffic offloading proxy apparatus; or
the non-core network service is a local network interactive service, and the non-core network service proxy apparatus is a local IP address access proxy apparatus.

3. The service data transmission processing method according to claim 1 , wherein before the receiving, by the service offloading apparatus, the IP address which is sent by the non-core network service proxy apparatus and is assigned to the user equipment, the method further comprises:
requesting, by the service offloading apparatus, the non-core network service proxy apparatus to establish, for the user equipment, the second service tunnel between the service offloading apparatus and the non-core network service proxy apparatus.

4. The service data transmission processing method according to claim 3 , wherein the service offloading apparatus requests the non-core network service proxy apparatus to assign the IP address to the user equipment and/or to establish, for the user equipment, the second service tunnel between the service offloading apparatus and the non-core network service proxy apparatus by sending a second create session request message to the non-core network service proxy apparatus.

5. A service data transmission processing method comprising:
when a service offloading apparatus obtains a first instruction from a serving gateway, requesting, by the service offloading apparatus, a core network service proxy apparatus to assign an IP address to a user equipment, wherein the first instruction is used for requesting the assignment of the IP address to the user equipment and/or establishment of a first service tunnel between the service offloading apparatus and the core network service proxy apparatus for the user equipment;
receiving, by the service offloading apparatus, the IP address which is sent by the core network service proxy apparatus and is assigned to the user equipment;
receiving, by the service offloading apparatus, uplink service data sent by the user equipment;
obtaining, by the service offloading apparatus, a service type of the uplink service data;
determining whether the service type of the uplink service data obtained by the service offloading apparatus is a core network service or a non-core network service;
if the service type of the uplink service data obtained by the service offloading apparatus is a core network service, sending, by the service offloading apparatus, the uplink service data to a core network service proxy apparatus through the first service tunnel; and
if the service type of the uplink service data obtained by the service offloading apparatus is a non-core network service, sending, by the service offloading apparatus, the uplink service data to a non-core network service proxy apparatus through a second service tunnel.

6. The service data transmission processing method according to claim 5 , wherein before the receiving, by the service offloading apparatus, the IP address which is sent by the core network service proxy apparatus and is assigned to the user equipment, the method further comprises:
requesting, by the service offloading apparatus, the core network service proxy apparatus to establish, for the user equipment, the first service tunnel between the service offloading apparatus and the core network service proxy apparatus.

7. The service data transmission processing method according to claim 6 , wherein the service offloading apparatus requests the core network service proxy apparatus to assign the IP address to the user equipment and/or to establish, for the user equipment, the first service tunnel between the service offloading apparatus and the core network service proxy apparatus by sending a first create session request message to the core network service proxy apparatus.

8. The service data transmission processing method according to claim 5 , wherein if the service offloading apparatus receives more than one IP address assigned to the user equipment, the method further comprises:
selecting, by the service offloading apparatus, an IP address of the user equipment from the more than one received IP address assigned to the user equipment as the IP address of the user equipment.

9. The service data transmission processing method according to claim 8 , wherein if the IP address, which is sent by the core network service proxy apparatus and is assigned to the user equipment, exists in the more than one IP address which is assigned to the user equipment and is received by the service offloading apparatus, the service offloading apparatus selects the IP address which is sent by the core network service proxy apparatus and is assigned to the user equipment as the IP address of the user equipment.

10. The service data transmission processing method according to claim 8 , wherein after the selecting, by the service offloading apparatus, the IP address of the user equipment from the more than one received IP address assigned to the user equipment, the method further comprises:
sending, by the service offloading apparatus, the IP address of the user equipment to the user equipment.

11. The service data transmission processing method according to claim 10 , wherein the sending, by the service offloading apparatus, the IP address of the user equipment to the user equipment is specifically:
sending, by the service offloading apparatus, the IP address of the user equipment to an evolved NodeB, and sending, by the evolved NodeB, the IP address of the user equipment to the user equipment.

12. The service data transmission processing method according to claim 11 , wherein the service offloading apparatus sends the IP address of the user equipment to the evolved NodeB through the serving gateway and a mobility management entity.

13. The service data tran
