Traffic flow splitting method and apparatus
First Claim
1. A method of traffic flow splitting, comprising:
- receiving, by user equipment (UE), a first multiflow aggregation instruction from an evolved NodeB (eNB) in a 3rd Generation Partnership Project (3GPP) network, wherein the first multiflow aggregation instruction is used to instruct the UE to establish a first multiflow aggregation channel between the UE and the eNB via a non-3GPP network, the first multiflow aggregation channel is used for transmitting a part of data in a downlink traffic flow for the UE, wherein the part of data is offloaded to the non-3GPP network for transmission, and other data in the downlink traffic flow is offloaded to a 3GPP channel that is in the 3GPP network and that is between the UE and the eNB for transmission, the first multiflow aggregation channel comprises a first subchannel between the UE and a multiflow aggregation gateway and a second subchannel between the multiflow aggregation gateway and the eNB; and
establishing, by the UE, the first multiflow aggregation channel, comprising;
obtaining, by the UE, an IP address of the multiflow aggregation gateway; and
sending, by the UE, a first multiflow aggregation channel establishment request to the multiflow aggregation gateway according to the IP address of the multiflow aggregation gateway, wherein the first multiflow aggregation channel establishment request comprises a second multiflow aggregation instruction and a bearer identifier corresponding to the second subchannel, the second multiflow aggregation instruction is used to instruct the multiflow aggregation gateway to establish the first multiflow aggregation channel.

Abstract
Embodiments of the present invention provide a traffic flow splitting method and apparatus. In a process of accessing a 3GPP network by UE, an eNB in the 3GPP network sends a first multiflow aggregation instruction to the UE, to instruct the UE to establish a first multiflow aggregation channel between the UE and the eNB via a non-3GPP network. The UE establishes the first multiflow aggregation channel. The first multiflow aggregation channel is used for transmitting a part of data in a downlink traffic flow for the UE, where the part of data is offloaded to the non-3GPP network for transmission, and other data in the downlink traffic flow is offloaded to a 3GPP channel for transmission. In the method, different data packets in a same traffic flow can be simultaneously transmitted in the 3GPP network and the non-3GPP network.
