Example Embodiment

[0027] Example one:

[0028] See below figure 1 , The service access control method in this embodiment includes:

[0029] 101. Obtain the amount of data transmitted by each service during the preset update time, and determine the bandwidth occupancy parameters of each service during the update time according to the data volume; among them, the service can be a service or a service flow. It is understandable that, In actual applications, the business can also adopt other data structure methods, which are not limited here;

[0030] In this step, determining the bandwidth occupancy parameters of each service during the update time according to the amount of data can be: the amount of data transmitted by the service during the preset update time is used as the bandwidth occupancy parameter of the service during the update time; or, The bandwidth occupation time ratio (BOTP, Bandwidth Occupied Time Proportion) is used as the bandwidth occupation parameter of the service during the upd...

Example Embodiment

[0037] Embodiment two:

[0038] Such as figure 2 As shown, this embodiment provides a service access control method, including:

[0039] 201. Obtain the amount of data transmitted by each service within a preset update time, and determine the bandwidth-to-time ratio of each service within the update time according to the data volume;

[0040] In this embodiment, the bandwidth time ratio BOTP within the update time is used as the evaluation index of channel access to reflect the measurement value of the channel bandwidth resource occupation by various services to determine the channel bandwidth resource allocation among the service streams. Fairness; in order to calculate the bandwidth-to-time ratio of each service, referring to Formula 1, it is necessary to first determine the total bandwidth occupation time of each service according to the amount of data transmitted by each service within the preset update time and the time required to transmit unit bit data. After that, the rat...

Example Embodiment

[0058] Embodiment three:

[0059] Such as image 3 As shown, this embodiment provides a service access control method, including:

[0060] 301. Obtain the amount of data transmitted by each service within a preset update time, and determine the bandwidth-to-time ratio of each service within the update time according to the amount of data;

[0061] The process of obtaining the bandwidth time ratio in this embodiment is the same as that in the foregoing embodiment, and will not be repeated here.

[0062] 302. Determine the service with the lowest bandwidth occupancy rate according to the bandwidth time ratio of each service and the corresponding bandwidth time ratio threshold.

[0063] In this embodiment, the lowest bandwidth occupancy rate is used as the preset adjustment condition; the way to determine the service with the lowest bandwidth occupancy rate is to calculate the actual bandwidth time of each service than BOTP i Compared with the respective preset bandwidth time ratio t...

Abstract

The embodiment of the invention belongs to the communication field and discloses a service access control method, a wireless access system and an access control device which are used for improving system performance. The method of the embodiment comprises the following steps: acquiring the sent data quantity of each service within refresh time, and determining the bandwidth occupation parameter of each service within the refresh time according to the data quantity; determining the service meeting an adjustment condition according to the bandwidth occupation parameter of each service and each corresponding bandwidth occupation parameter threshold; and adjusting the access priority level of the service meeting the adjustment condition. The embodiment of the invention can adjust the access priority levels of different services according to bandwidth occupation ratios, thereby balancing the access priority level of each service, decreasing the packet loss ratios of the services with low priority levels, and improving the system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service access control method, a wireless access system and an access control device. Background technique [0002] With the development of wireless communication technology, the service provided by Wireless Mesh Network (WMN, Wireless MeshNetwork) has developed from the single data service in the past to the multimedia service stage of voice, streaming media and data. Different multimedia services have different requirements for QoS (Quality of Service). For example, voice services and video streaming services are real-time services that have high requirements for network delay, while data services have relatively low requirements for network delay. Much lower; voice and data services have higher requirements on packet loss rate, relatively speaking, video streaming services have lower requirements on packet loss rate. In practical applications, it is necessary to provide di...
