1. A traffic offload method, comprising:
- receiving, by a first traffic offload function entity, user information that is of a user equipment within coverage of the first traffic offload function entity and sent by a core network device or a second traffic offload function entity, wherein the first traffic offload function entity is a traffic offload function entity corresponding to the user equipment after a handover, and the second traffic offload function entity is a traffic offload function entity corresponding to the user equipment before the handover;
obtaining, by the first traffic offload function entity, a traffic offload policy, wherein the traffic offload policy is obtained by;
obtaining, by the first traffic offload function entity, the traffic offload policy stored by the first traffic offload function entity;
orreceiving, by the first traffic offload function entity, the traffic offload policy sent by the core network device, wherein receiving the traffic offload policy comprises;
sending, by the first traffic offload function entity, a service request message to the core network device and receiving a radio access bearer assignment message sent by the core network device, wherein the radio access bearer assignment message carries the traffic offload policy;
orsending, by the first traffic offload function entity, an access point name delivery request message to the core network device, and receiving the traffic offload policy delivered by the core network device;
orreporting, by the first traffic offload function entity, a traffic offload capability or identifier of the first traffic offload function entity to the core network device, and receiving the traffic offload policy delivered by the core network device;
matching the traffic offload policy with the user information; and
offloading, by the first traffic offload function entity, traffic corresponding to the user equipment according to the user information that successfully matches the traffic offload policy.

16. A first traffic offload function entity, comprising:
-
an information receiving module, configured to receive user information that is of a user equipment within coverage of the first traffic offload function entity and sent by a core network device or a second traffic offload function entity, wherein the first traffic offload function entity is a traffic offload function entity corresponding to the user equipment after a handover, and the second traffic offload function entity is a traffic offload function entity corresponding to the user equipment before the handover; a policy obtaining module, configured to obtain a traffic offload policy; a matching module, configured to match the user information received by the information receiving module with the traffic offload policy obtained by the policy obtaining module; and a traffic offloading module, configured to offload traffic corresponding to the user equipment according to the user information that successfully matches the traffic offload policy; wherein the information receiving module is specifically configured to send a service request message to the core network device, and to receive a radio access bearer assignment message sent by the core network device, wherein the radio access bearer assignment message carries the user information of the user equipment within the coverage of the first traffic offload function entity;
orwherein the information receiving module is specifically configured to send an access point name delivery request message to the core network device and receive the user information that is of the user equipment within the coverage of the first traffic offload function entity and delivered by the core network device;
orwherein the information receiving module is specifically configured to report a traffic offload capability or identifier of the first traffic offload function entity to the core network device and receive the user information that is of the user equipment within the coverage of the first traffic offload function entity and delivered by the core network device. - View Dependent Claims (17, 18)
