Convergence transmission system, device and method for data diversion and convergence

Abstract

A converged transmission system, comprising a data offloading and converging point, a wireless cellular access point, and a wireless local area network WLAN access point; the data offloading and converging point is used to negotiate with a user equipment UE to determine a data offloading strategy; according to the negotiation with the UE A determined data offload strategy, using the WLAN radio bearer to transmit part of the user data, the WLAN radio bearer is obtained by configuring a part of the radio bearer in the wireless cellular system as a WLAN radio link; and using the rest of the radio bearer in the wireless cellular system transmitting the rest of the user data, wherein the wireless bearer is the wireless part of the bearer channel of the wireless cellular system, and the bearer channel of the wireless cellular system is established through control plane signaling of the wireless cellular system; the WLAN access point uses The wireless cellular access point is configured to transmit the remaining part of the user data with the UE and the data distribution and convergence point.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a convergence transmission system, device and data diversion and convergence method. Background technique [0002] With the rapid development of smart phones, more and more mobile communication terminals have integrated WLAN (WirelessLocalAreaNetwork, wireless local area network; commonly known as WiFi, WirelessFidelity, wireless fidelity technology) communication module; With the increasing demand for mobile broadband, the existing wireless cellular communication system is under the pressure of increasing data traffic. [0003] A feasible method is to integrate the wireless cellular technology and the WLAN technology, and use the WLAN to offload the data traffic of the mobile cellular communication system in order to improve the user experience of the cellular system. However, the existing WLAN networking methods all have a common feature, that is, the WLAN is a completely...

AI Technical Summary

Problems solved by technology

Because the WLAN network and the cellular network are independent, the transmission delay of IP packets is very different and uncontrollable. The transmission of the same IP data stream on such two networks will cause serious disorder, resulting in a decline in service quality.

[0004] It can be seen that the existing mutual integration method greatly increases the cycle and cost of network construction, and makes the service quality of mobile communication network not high
