一种数据传输方法及装置
Abstract:
(EN)
Provided in the present application are a data transmission method and device, used for solving the problem in the prior art that when BBUs of base stations are centrally positioned, the connection between an RRU and a BBU cannot be realized because of the large distance therebetween as RRUs are deployed in a distributed manner and BBUs are deployed in a centralized manner. The method is as follows: a transmitting device can encapsulate CPRI data to be sent into an Ethernet frame, so as to utilize the deployed Ethernet to transmit the Ethernet frame to a receiving device. Thus, the transmitting device and the receiving device can utilize respective network devices deployed in the Ethernet to realize the transmission of the CPRI data. Since the transmitting device and the receiving device use the existing Ethernet therebetween, and the existing Ethernet is widely distributed and does not limit the distance between the transmitting device and the receiving device when transmitting data, the described solution can realize the connection between an RRU deployed in a distributed manner and a BBU deployed in a centralized manner.
(FR)
La présente invention concerne un procédé et un dispositif de transmission de données, utilisés pour résoudre le problème de l'état de la technique selon lequel, lorsque les BBU de stations de base sont positionnées au centre, la connexion entre une RRU et une BBU ne peut pas être réalisée en raison de la grande distance entre celles-ci, puisque les RRU sont déployées de manière distribuée et que les BBU sont déployées de manière centralisée. Le procédé est le suivant : un dispositif de transmission peut encapsuler des données CPRI à envoyer à l'intérieur d'une trame Ethernet, de façon à utiliser l'Ethernet déployé pour transmettre la trame Ethernet à un dispositif de réception. Ainsi, le dispositif de transmission et le dispositif de réception peuvent utiliser des dispositifs de réseau respectifs déployés dans l'Ethernet pour réaliser la transmission des données CPRI. Étant donné que le dispositif d'émission et le dispositif de réception utilisent l'Ethernet existant entre ceux-ci, et que l'Ethernet existant est largement distribué et ne limite pas la distance entre le dispositif d'émission et le dispositif de réception lors de la transmission de données, la solution décrite permet de réaliser la connexion entre une RRU déployée d'une manière distribuée et une BBU déployée d'une manière centralisée.
(ZH)
本申请提供了一种数据传输方法及装置,用以解决现有技术中在基站的BBU集中放置时,分布式部署的RRU和集中式部署的BBU之间距离较大,无法实现RRU和BBU之间连接的问题。该方法为:发送设备可以将待发送的CPRI数据封装在以太网帧中,从而可以利用已经部署的以太网将所述以太网帧传输至接收设备。这样,发送设备和接收设备之间可以利用部署在所述以太网中的各网络设备,实现CPRI数据的传输。由于所述发送设备和所述接收设备之间采用现有的以太网,且现有的以太网分布广泛,传输数据时不限定发送设备和接收设备之间的距离,因此,通过上述方案,可以实现分布式部署的RRU和集中式部署的BBU之间的连接。
