Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0050] In order to meet customers' increasing demand for bandwidth and reduce cost per bit, wireless communication technology has also evolved accordingly. Compared with 4G, the latest 5G technology has larger channel bandwidth and more and more data transmitted by the fronthaul interface; in addition, the commonly used frequency bands of 5G are medium and high frequency bands, and the coverage area of ​​the cell is relatively small, so the number of base stations required There are...

Abstract

The invention provides a forward transmission network data processing device and method, the device comprises a processor, at least one high-speed forward transmission interface and at least one low-speed forward transmission interface. The processor comprises a protocol frame processing module used for converging data uploaded by a plurality of low-speed forward transmission interfaces into a group of data as first target data; selecting one of the high-speed forward interfaces as a first target interface, and sending the first target data to forward network transmission equipment through thefirst target interface; and selecting one of the high-speed forward interfaces as a second target interface, receiving the data issued by the forward network transmission equipment through the secondtarget interface as second target data, and finally distributing the second target data to the corresponding low-speed forward interface. According to the method and the device, the interconnection problem of low-speed forward transmission interfaces and forward transmission network transmission equipment of various wireless devices can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a fronthaul network data processing device and method. Background technique [0002] With the further evolution of wireless technology, major changes have taken place in the wireless network access network architecture. Taking 4G technology and 5G technology as examples, the evolution of network architecture is as follows: figure 1 As shown, the fronthaul network also changes accordingly. For 4G technology, the fronthaul network is the network between the baseband processing unit (BBU) and the radio frequency processing unit (RRU). The BBU and the RRU generally communicate directly through dark optical fibers. The fronthaul interface Comply with the CPRI protocol; for 5G technology, the fronthaul network is the network between the distribution unit (DU) and the active antenna unit (AAU), and the CU+DU combined device communicates with the AAU through the fron...
