Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] An embodiment of the present invention provides a method for processing Ethernet data of cascaded BBUs, such as figure 1 As shown, the method includes the steps of:

[0042]S110, the baseband unit BBU participating in the cascading is provided with at least two different virtual local area networks, wherein one virtual local area network is a virtual local area network for processing the Ethernet data inside the current level BBU, marked as V1, and the other virtual local area network is The virtual local area network used to process Ethernet data between BBU cascades is marked as V2; in ot...

Abstract

Disclosed in the present invention are an Ethernet data processing method of cascaded Base Band Units (BBUs) and a BBU of a base station. Each Ethernet data process module in the BBU involved in cascade is divided into at least two different virtual local area networks according to beared different Ethernet data functions, wherein one virtual local area network V1 is used to process the Ethernet data between the BBUs in the same level, and another virtual local area network V2 is used to process the Ethernet data between the cascaded BBUs. The virtual local area network V1 processes the Ethernet data between the BBUs in the same level, and the virtual local area network V2 processes the Ethernet data between the cascaded BBUs. The Ethernet data inside the virtual local area network V1 cannot be passed into the virtual local area network V2, and meanwhile the Ethernet data in the local area network V2 cannot be passed into the virtual local area network V1. The crosstalk in the Ethernet data can be avoided between the cascaded BBUs and the BBU cascade can have better extensibility.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an Ethernet data processing method of cascaded BBUs and a BBU of a base station. Background technique [0002] With the evolution of technical standards for mobile communication base stations, the requirements for the service data processing capability of the BBU (Base Band Unit, baseband unit) of the base station tend to be accelerated. At the same time, with the accelerated evolution of the all-IP (Internet Protocol, network protocol) base station, the importance of the Ethernet-based BBU cascading of the base station has risen to a new important level, but the Ethernet-based cascading in the base station There are technical problems with the BBU's Ethernet data processing method: [0003] In the prior art, there is crosstalk in the Ethernet data between BBUs cascaded in an Ethernet-based manner; and in the prior art, the scalability of BBU cascading is not strong.
