Problems solved by technology

However, since some user plane data needs to be transmitted in the macro base station with high QoS (Quality of Service, service quality) guarantee, and some control plane signaling has lower requirements on QoS, and does not need to occupy system resources with high QoS guarantee, therefore, Simple division of user plane data and control plane signaling results in poor service QoS and low utilization of system resources

Abstract

The embodiment of the invention provides a data transmission method and device and a communication system, and relates to the field of communications. The data transmission method and device and the communication system can guarantee QoS and improve system resource utilization ratio. The method includes the steps that a configuration request message is sent to an access node by a macro base station, wherein the configuration request message includes bearer configuration parameters carrying wireless RB identification; a configuration success message from the access node is received by the macro base station, wherein the configuration success message at least carries configuration messages of physical layer parameters configured for user equipment by the access node; a reconfiguration message is sent to the user equipment by the macro base station, wherein the reconfiguration message at least includes the step of reconfiguring the RB identification transmitted on the access node and / or logical channel identification transmitted on the access node and the physical layer parameter configuration messages of the access node so that the user equipment can send signals and / or service data to the access node according to reconfigured RB identification transmitted to the access node and / or reconfigured logic channel identification transmitted to the access node after physical layer configuration is accomplished by the user equipment according to the physical layer parameter configuration messages.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, device and communication system. Background technique [0002] With the development of mobile communication technology and the large-scale deployment of 3G (3rd-generation, third-generation mobile communication technology) networks, high-speed, large-bandwidth communication services have greatly improved user experience. However, although the large-scale popularization of smart phones has injected new vitality into the communication business, it has also brought more challenges to the operation of the communication business. Due to the limited throughput of the 3G network, it cannot meet such a huge traffic, and the currently operating network is under great pressure. Even the large-scale deployment of LTE (Long Term Evolution, long-term evolution system) in the future can only meet part of the demand. [0003] The separation of user plane data and c...
