Baseband unit, base station, and data forwarding processing method

Abstract

The embodiment of the invention provides a baseband unit, a base station, and a data forwarding processing method. Data to be forwarded are received by a front end switching module, then a forwardingcontrol module performs forwarding path matching on the data received by the front end switching module according to a preset forwarding flow table, and forwards the data to a data exchange sub-modulein a transmission interface module when determining the presence of data to be forwarded to the transmission interface module according to the matching result; and since the forwarding path matchingprocess is advanced, when a certain pieces of data is not sent to the transmission interface module, the data does not need to pass through the data exchange sub-module, but can be directly transmitted by the forwarding control module through the front end switching module, thereby avoiding a data return process between the data exchange sub-module and the forwarding control module, so that the delay is shortened, the data transmission mount within a unit time is improved, and the bandwidth is further improved, then better user experience can be obtained as a result.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a baseband unit, a base station and a data forwarding processing method. Background technique [0002] In wireless base station equipment, multiple physical boards usually cooperate to complete the functions of the base station. Based on the consideration of security and saving IP (Internet Protocol, Internet Protocol) resources, the communication between the base station and the core network is through the baseband unit The external IP of the base station is configured on the transmission interface module. The transmission interface module can be a specific physical board or a virtual device (such as a virtual machine or a Docker container). In this way, the transmission interface module is equivalent to a NAT (Network Address Translation, Network Address Translation) device capable of deeply analyzing packets.

Problems solved by technology

[0003] Existing baseband units often include a transmission interface module, a traditional switching module, and a baseband processing module. Among them, the transmission interface module includes a network card and a forwarding module. It must be sent by the traditional switching module to the network card of the transmission interface module, and then transmitted to the forwarding module through the network card of the transmission interface module, so as to determine its forwarding path. For the data that needs to be transmitted to the core network or baseband processing module, the After the data is forwarded by the forwarding module to determine its forwarding path, the data will be transmitted by the forwarding module to the network card of the transmission interface module, that is, there is a data return process between the forwarding module and the network card, and the return process increases The delay of data communication between the core network and the base station is reduced. As the delay increases, the data transmitted per unit time will decrease, thus reducing the bandwidth.
