[0041] figure 2 Is a schematic diagram of the control word processing device provided by the second embodiment of the present invention, which is composed of figure 2 It can be seen that, in this embodiment, the control word processing device 2 provided by the present invention includes a processor 21 and a control word device 22, wherein:

[0042] The processor 21 is configured to obtain the multiplexing attribute of the control word to be processed, and configure the control word device corresponding to the control word according to the multiplexing attribute, and the multiplexing attribute includes whether the control word is time-division multiplexed;

[0043] The control word device 22 is used to process control words.

[0044] In some embodiments, such as figure 2 As shown, the control word processing device 2 further includes a control word configuration device 23. The processor 21 is specifically configured to determine the control word configuration device 23 corresponding...

no. 3 example

[0051] In this embodiment, the control words of the two multiplexing attributes, the reception and transmission of control words, and the generation of interrupts are respectively described in detail, and the following device takes a register as an example for description. details as follows:

[0052] Such as image 3 As shown, a time division multiplexed control word table (Time DivisionControl Word Table) is formed by several memory arrays, and the bit width of each control word table is the specified bit width N (16bit, 32bit, etc.) of the control word in the CPRI system. The depth of the control word table is M (16, 32, etc.); the control word table needs to be addressed uniformly, but the reading and writing of the control word inside can be read and written indirectly through other registers or uniformly addressed. According to the system and future upgrade planning, the number of control word tables can be customized. These memories can be realized by registers or various ...

Abstract

A control word processing method, device and communication system, the method comprising: acquiring a multiplexing attribute of a control word to be processed, the multiplexing attribute comprising whether the control word is time division multiplexing; configuring a control word device corresponding to the control word according to the multiplexing attribute; and the control word device processes the control word. The above technical solution enables a combination of software and hardware during the control word processing, thus reducing complexity for achieving a circuit, and completing a function upgrade of the circuit through a software upgrade.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a control word processing method, device and communication system in a communication system established based on the CPRI protocol. Background technique [0002] When using the CPRI (Common Public Radio Interface, Common Public Radio Interface) protocol to establish a communication system, such as the BBU (Building Baseband Unit, indoor baseband processing unit) and RRU (Radio Remote Unit) that use CPRI protocol networking , The BBU needs to send a control word to the RRU to complete the control function of the RRU, and at the same time, the BBU also needs to receive the control word sent by the RRU to monitor the status of the RRU in real time. When multiple RRUs and BBUs are used for networking, such as chain, ring networking, etc., it is generally necessary to realize the time division multiplexing of the control word sent / received by the superframe number, for e...
