A method and device for access control

Abstract

Provided are an admission control method and device, which relate to the field of communications, and can solve the problem of network congestion caused by inconsistent management of bandwidths on two sides of a heterogeneous network, and improve the transmission quality of network service. The method comprises: any network element at both ends of a network calculating a physical layer bandwidth occupied by a current service data stream, the remaining bandwidth in the link of the network element and a bandwidth occupied by a new service, and when the remaining bandwidth in the link is smaller than the bandwidth occupied by the new service, generating bandwidth information, and sending same to an admission control device; in accordance with the bandwidth information, the admission control device generating admission information, and sending same to network elements at both ends of the network, the admission information carrying an instruction to stop the new service from accessing; and the network elements at both ends of the network receiving the admission information sent by the admission control device, and stopping the new service from accessing in accordance with the admission information. The embodiments of the present invention are applied to control the access of a new network service.

Description

technical field [0001] The present invention relates to the communication field, in particular to an admission control method and device. Background technique [0002] There is a transmission conversion device between the BSC (BaseStationController, base station controller) and BTS (BaseTransceiverStation, base transceiver station), the link type on the BSC side is inconsistent with the link type on the BTS side, and the same service data is used on the BSC side and the BTS side Different link layer overheads lead to different physical bandwidths actually occupied, which brings difficulties to bandwidth management and call admission control. [0003] The call service data passes through the BSC side and the BTS side. Assuming that the link types on both sides are the same, the header overhead used to transmit the service data is the same, and the fixed header overhead and bandwidth are deducted for each service. The same physical bandwidth is configured on the BSC side and ...
