Abstract:
The present application relates to the technology of communications. Disclosed are a method and device for shunting IP streams during 3GPP access switching; after having received a command for 3GPP access switching transmitted by a source 3GPP access device, a user equipment (UE) determines the IP streams to be transferred, and then performs 3GPP access switching and IP stream transferring at the same time, thus improving IP stream transferring efficiency. In addition, the IP streams to be transferred contain an IP stream capable of being transmitted via WLAN access after a target 3GPP access device fails to allocate resources to a bearers for transmitting the IP stream, thereby avoiding service interruption due to bearer loss, and thus improving the QoS ensurance for the service.
