Problems solved by technology

[0009] Although the full selection scheme can satisfy the maximum flexibility of RRU cascade connection, no matter what method is used to realize this selection, a large number of selectors must be used, so a large amount of network resources will be wasted
If there are many CP RI links, the resources occupied by selecting links will increase exponentially, and the system will not be able to provide enough resources for other functions, and its practicality is greatly limited at this time

Embodiment Construction

[0029] The core of the present invention is that when multiple AxC data channels are selected, the AxC data channels to be selected are randomly grouped, the data channels in each group cannot be repeated, and several selectors for each data channel group are used to perform channel For selection, a sorting selection circuit for arranging the order of each selected channel is arranged at the channel selection output terminal.

[0030] Specifically speaking, when the present invention selects a plurality of AxC data channels, the AxC data channels to be selected are first randomly grouped, and then each channel group is selected using several selectors for the data channel group, Finally, after all the selectors complete the channel selection, the sequence selection circuit is used to perform full selection for the selected channels.

[0031] The key point of the present invention is to perform random group selection on the data channels to be selected before fully selecting th...

Abstract

A method for selecting data channel packet includes carrying out packet on data channel to be selected based on random distribution algorithm and carrying out data channel selection on each data channel set having been packeted, carrying out full selection on selected data channels obtained through selection and using full selection to control output sequence of data in data channel.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data channel grouping selection method and device. Background technique [0002] CPRI (Common Public Radio Interface) is a common wireless interface protocol in wireless communication systems. The CPRI interface is a high-speed interface. Each CPRI frame can transmit a lot of single-antenna single-cell (AxC) data. In the case of being connected, different remote base stations (hereinafter referred to as RRUs) use different AxC data channels on the CPRI link. In this way, when performing data transmission, the local base station needs to select different data channels in the CPRI link. [0003] In order to support the flexibility of RRU cascade connection, the local base station generally adopts a full selection scheme for data channel selection. [0004] The full selection scheme applied to data channel selection refers to selecting the required objects from all...
