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.

Embodiment 1

[0028] When the base station communicates with the core network, the base station often realizes data interaction with the core network through its baseband unit. Please refer to figure 1 as shown, figure 1 It is a schematic structural diagram of an existing baseband unit. The existing baseband unit often includes a transmission interface module 11, a traditional switching module 12, and a baseband processing module 13, and only after the transmission interface module 11 receives data through its network card 111 can it be processed The data is matched with the forwarding path. For example, when the traditional switching module 12 receives the data sent by the core network, it will send the data to the network card 111 of the transmission interface module 11, and then the network card 111 of the transmission interface module 11 will send it to The forwarding module 112 in the transmission interface module 11, the forwarding module 112 performs forwarding path matching on the d...

Embodiment 2

[0059] The embodiment of the present invention provides a data forwarding processing method, please refer to Figure 7 As shown, the data forwarding processing method provided in this embodiment can be applied in the baseband unit, including:

[0060] S701: the front-end switching module receives the data to be forwarded;

[0061] S702: The forwarding control module performs forwarding path matching on the data received by the front-end switching module according to the preset forwarding flow table, and forwards the data to the transmission interface when determining that there is data to be forwarded to the transmission interface module according to the matching result The data exchange sub-module in the module.

[0062] The forwarding flow table in this embodiment includes a strategy for determining the forwarding path corresponding to the data.

[0063] It should be noted that the data to be forwarded received by the front-end switching module in the above step S701 may n...

Abstract

The embodiment of the present invention provides a baseband unit, a base station, and a data forwarding processing method. The data to be forwarded is received by the front-end switching module, and then the forwarding control module performs forwarding path matching on the data received by the front-end switching module according to the preset forwarding flow table. , when it is determined that there is data to be forwarded to the transmission interface module according to the matching result, the data is forwarded to the data exchange sub-module in the transmission interface module; since the forwarding path matching process is advanced, when a certain 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 sent directly by the forwarding control module through the front-end switching module, which avoids the data return process between the data exchange sub-module and the forwarding control module, thus reducing the time Delay increases the amount of data transmission per unit time and further increases the bandwidth, so users can get a better experience.

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. [0003] Existing baseband units often include a tran...
