Problems solved by technology

[0024] However, according to statistics, the service bandwidth utilization rate of UGS is low, only reaching 50%.
At the same time, considering that the sum of the Maximum Sustained Traffic Rate of VoIP services is generally 2-4 times the actual bandwidth of the air interface, or even higher, the utilization rate in this mode is lower
If the VoIP service is UGS, it will greatly occupy the bandwidth of the air interface, resulting in a decrease in bandwidth utilization.
Such bandwidth scheduling is also unreasonable

Embodiment Construction

[0051] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] Figure 5 shows a bandwidth scheduling method according to an embodiment of the present invention, Figure 6 An information interaction diagram according to an embodiment of the present invention is shown. Such as Figure 5 and Figure 6 As shown, in step S502, before establishing the VoIP service, the base station BS 604 acquires the attribute of the VoIP service and sets the scheduling mode of the service. Here, there are many ways to implement step S502: Method 1: During the VoIP service establishment signaling interaction process, the GW perceives the establishment of the service, and there are many ways to perceive the service, for example, by analyzing the signaling message, through the GW at the same time Signaling protocol between BSs, setting up VoIP service connections and corresponding QoS scheduling configurations; method 2: when...

Abstract

This invention provides a method for dispatching bandwidth and a device, which judges if the residual bandwidth on the WIMAX link meets the maximum one for setting up VoIPservice requirement by sensing service, identifying and setting up VoIP service and dispatching bandwidth, if it meets the requirement, it preserves the maximum bandwidth of the VoIP service, otherwise, it does not respond the bandwidth request, when a user station transmits a request of phone communication bandwidth to the base station, the base station judges if it has preserved a bandwidth for the VoIP service, if so, it distributes it for the phone communication, otherwise, it returns the judgment, which increases the usability of VoIP service bandwidth to utilize resources of empty bandwidth.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, the present invention relates to a bandwidth scheduling method and device. Background technique [0002] VoIP (Voice over IP) is a voice signal or video signal transmitted through an IP network, so VoIP is a technology that can transmit analog audio or video on an IP network. Simply put, it uses a series of procedures such as transcoding, encoding, compression, packaging, etc., so that the voice data can be transmitted to the destination through the IP network, and then through the opposite process, it is restored to the original voice signal for the listener received technology. VoIP is based on the packetization and digital transmission technology of IP technology. Its basic principle is: compress and code the voice data through the voice compression algorithm, and then package the voice data according to IP and other related protocols, and transfer them through the IP ...
