Embodiment Construction

[0067] Usually, the amount of uplink communication data from each RE to REC is not synchronous and average, but bursty and not fixed. Therefore, when the overall bandwidth of HDLC is limited, the existing technology pre-sets for each RE and REC The method of allocating fixed bandwidth between uplink HDLC links lacks flexibility and cannot realize dynamic allocation and sharing of bandwidth, which may lead to problems such as low bandwidth utilization and bandwidth waste.

[0068] For this reason, the embodiment of the present invention provides a dynamic bandwidth allocation method to realize the dynamic bandwidth allocation of the uplink HDLC sub-link from RE to REC, so as to realize bandwidth allocation on demand and improve bandwidth utilization. In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to the use of HDLC (High-Level Data Link Control, advanced data link) encapsulated in CPRI (Common Public Radio Interface, general public radio interface) between radio frequency units and baseband units of mobile communication base stations A method and device for allocating bandwidth of an HDLC link when the link performs data interaction. Background technique [0002] In the base station system of mobile communication, a single base station is generally divided into a baseband part and a radio frequency part. When building a single base station, the radio frequency part and the baseband part can be combined to form a centralized base station, or they can be placed independently to form a distributed base station system. [0003] With the development of mobile communication technology, especially in the third-generation mobile communication system, the tradit...
