Description

Communication method and communication device

Technical field

The present invention relates to the field of communications and, more particularly, to a communication method and communication device.

Background technique

In order to make full use of network resources and enhance user experience, the existing 3rd Generation Partnership Project (3GPP) standard has proposed the technology of interconnecting 3GPP networks and WLAN networks, and using WLAN networks to offload data from 3GPP networks. . The main discussion in the current standard is based on data offloading of the 3GPP core network. As shown in FIG. 1, if the WLAN network is a trusted network, the WLAN network can be directly connected to the Packet Data Network Gateway (PDN-GW) of the 3GPP core network through the S2a interface; if the WLAN network is an untrusted network The WLAN network can access the Evolved Packet Data Gateway (ePDG) through the SWn interface, and then the ePDG is directly connected to the PDN-GW of the 3GPP core network through the S2b interface.

In the prior art, whether the WLAN network belongs to a trusted network or an untrusted network, the services in the 3GPP network are offloaded by the PDN-GW in the 3GPP core network. Specifically, the following data transmission is taken as an example. The PDN-GW receives data sent by the packet data network to the user equipment, and the PDN-GW further determines whether the data needs to be offloaded to the WLAN network according to the data offload policy. If the data needs to be offloaded to the WLAN network, the PDN-GW sends the data to the user equipment over the WLAN network. However, since the PDN-GW is a device in the 3GPP core network, the PDN-GW cannot consider the current link quality of the user equipment in the access network, the load of the 3GPP network, and the load of the WLAN network when determining whether to perform data offloading. The factor that may cause the PDN-GW to make an unloading decision is not the optimal solution in the current network state, thereby reducing system performance.
