Problems solved by technology

In order to meet the demand for the doubled increase in RRU data volume, it is necessary to replace the laid cables on a large scale, which is very difficult to implement
Therefore, the data transmission method of the wireless network in the prior art cannot make C-RAN widely used in actual deployment scenarios where BH network bandwidth resources are limited

Abstract

Provided are a method, device and system for transmitting data of a wireless access network, which relate to the field of mobile communication networks. The method comprises: receiving, by a multicast relationship processing apparatus, a multicast group configuration message sent by a multicast control apparatus, the multicast group configuration message indicating multicast group member relationship determined by the correlation between each coordination set and each multicast group; and configuring, by the multicast relationship processing apparatus, multicast data transmission according to the multicast group member relationship and relevant BH network elements of each multicast group. In the present invention, a multicast control apparatus sends a multicast group member relationship determined by the correlation between each coordination set and each multicast group to a multicast relationship processing apparatus, which enables the multicast control apparatus to configure multicast data transmission with relevant BH network elements of each multicast group.

Description

technical field [0001] The invention relates to the field of mobile communication networks, in particular to a data transmission method, device and system for a wireless access network. Background technique [0002] C-RAN (Cloud-Radio Access Network, Cloud-Radio Access Network) is a new radio access network architecture proposed according to the current network conditions and the trend of technological progress. C-RAN uses a cloud-based baseband pool to control distributed RRUs (Remote Radio Units, remote radio units), which makes collaboration between cells more convenient, and can be achieved through a wide range of CoMP (Coordinated Multi-point, multi-coordinated Point transmission), therefore, the data transmission of this wireless access network can effectively reduce the interference between cells, increase the capacity of the wireless network, improve the performance of edge users, save energy, reduce costs, etc., but, at the same time, C-RAN The bandwidth of the BH ...
