METHOD AND DEVICE FOR ALLOCATING BANDWIDTH OF HIGH-LEVEL DATA LINK CONTROL LINK

摘要

The present invention provides a method and device for allocating a bandwidth of a high-level data link control link. The method is applied to a common public radio interface CPRI link formed by a radio equipment controller REC and over two radio equipments REs through link networking and comprises: an RE making statistics on communication traffic from the RE to an uplink HDLC sub-link of the REC; the RE determining, according to the communication traffic obtained through statistics and a current link bandwidth of the uplink HDLC sub-link, whether it is needed to adjust a link bandwidth of the uplink HDLC sub-link; when the RE determines that the link bandwidth of the uplink HDLC sub-link needs to be adjusted, sending a bandwidth adjustment request message to the REC; and the RE, together with the REC, adjusting the link bandwidth of the uplink HDLC sub-link according to a bandwidth adjustment response message that is returned by the REC and carries bandwidth adjustment amount.
