Abstract: A data transmission method, an apparatus, and a network system are used to transmit common public radio interface (CPRI) data in the Ethernet, and can support CPRI data corresponding to multiple service flows to be exchanged between multiple RRUs and multiple BBUs in any network by using an existing switching device from point to point, point to multipoint, and multipoint to multipoint. This not only reduces CPRI networking costs, but also improves CPRI networking flexibility. A specific implementation method includes: receiving, by a sending apparatus, CPRI data, where the CPRI data includes CPRI data of at least one service flow; parsing out, from the CPRI data, a CPRI data payload corresponding to each service flow, and separately encapsulating, based on a dedicated processing frame header of each service flow, the CPRI data payload of the corresponding service flow, to obtain a packet of each service flow.
Abstract translation: 使用数据传输方法，装置和网络系统来传输以太网中的公共无线电接口（CPRI）数据，并且可以支持在多个RRU和任何网络中的多个BBU之间交换对应于多个业务流的CPRI数据 通过使用现有的交换设备，从点到点，点到多点，以及多点到多点。 这不仅降低了CPRI的网络成本，而且提高了CPRI网络的灵活性。 具体实现方法包括：由发送装置接收CPRI数据，其中CPRI数据包括至少一个服务流的CPRI数据; 从CPRI数据中分析出与每个服务流相对应的CPRI数据净荷，并且基于每个服务流的专用处理帧报头单独地封装相应服务流的CPRI数据有效载荷，以获得每个服务流的分组 服务流程。

Abstract: A apparatus and system for exchanging data of an edge area user on a C-RAN are provided. The apparatus includes: at least one collaborative station of at least one neighboring C-RAN is determined for the edge area user on the C-RAN; control data is exchanged with the neighboring C-RAN collaborative station; a data exchange path used for exchanging first data with the neighboring C-RAN collaborative station is established according to the control data; the neighboring C-RAN collaborative station exchanges second data with the edge area user according to the control data. Based on the foregoing innovative mechanism, the C-RAN master station performs coupled collaboration with the neighboring C-RAN collaborative station by establishing the data exchange path, so that the neighboring C-RAN collaborative station may also exchange data with the edge area user, thereby enabling the edge area user on the C-RAN to obtain a better gain and improving system performance.
