Example Embodiment

[0105] Example one

[0106] In this embodiment, the LTE system and the WLAN system are taken as examples to illustrate the signaling flow of the base station to establish the offloading and de-offloading processes.

[0107] Base station side:

[0108] Step 0: The base station maintains the UE for basic LTE link establishment and data communication procedures;

[0109] Step 1: When the base station finds that the UE moves under the coverage of the AP through various auxiliary information, such as the measurement of the base station and the report of the UE, and the load under the AP is lighter and meets various conditions of offloading, the base station sends RRC signaling In the process, the UE is configured to inform the UE to offload part or all of the DRB / data stream to the WLAN link for transmission. The RRC configuration signaling needs to carry one of the following:

[0110] Distributed to the DRB list under WLAN;

[0111] List of DRBs kept under LTE;

[0112] Filter template info...

Example Embodiment

[0130] Embodiment two

[0131] In this embodiment, the LTE system and the WLAN system are taken as examples to illustrate the signaling process for the base station to modify the offload filtering template.

[0132] Base station side:

[0133] Step 0: The base station maintains the UE for basic LTE link establishment, and maintains the data communication process of the LTE link and the WLAN link offload filter template;

[0134] Step 1: When the base station finds that the link of the UE or the load of AP / LTE has changed through various auxiliary information, such as the measurement of the base station and the report of the UE, and the offload filtering template needs to be changed, the base station passes the RRC signaling process , Configure the UE and inform the UE of the new offload filtering template. The RRC configuration signaling needs to carry one of the following:

[0135] Distributed to the DRB list under WLAN;

[0136] List of DRBs kept under LTE;

[0137] Filter template in...

Abstract

The present invention relates to communications technology. Disclosed are a data stream transmission method and device, the method comprising: when a base station determines that a UE is covered by an access point (AP) satisfying an offload condition, the base station instructs the UE to transmit all or part of the data stream via a WLAN link; the UE transmits all or part of the data stream via the WLAN link according to the offload instruction, thus achieving the cooperative transmission between a mobile communication network and the WLAN network, ensuring the capability of the user transmitting data via an optimized network, and improving the quality of data transmission.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data stream transmission method and device. Background technique [0002] With the growth of user demands and the development of communication technologies, there are more types of wireless communication technologies and related networks. For example, there are 2G / 3G / 4G mobile communication technologies and networks that can provide wide coverage, and Wifi ( wireless fidelity, wireless fidelity) technology and WLAN (Wireless LocalArea Network wireless local area network) network. Therefore, a large number of scenarios where different communication networks coexist, such as scenarios where 2G / 3G / 4G networks and WLANs coexist, also appear. [0003] The EPS (Evolved Packet System, Evolved Packet System) system is a system that supports multiple access technologies and mobility between multiple accesses. In a multi-access scenario, the terminal may be under common coverage of m...
