一种信道配置方法及系统、接入控制器A channel configuration method and system, access controller

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种信道配置方法及系统、接入控制器(英文全称为：Access Controller，缩写为：AC)。The present invention relates to the field of communication technologies, and in particular to a channel configuration method and system, and an access controller (English full name: Access Controller, abbreviated as: AC).

背景技术Background technique

频谱规划和优化是网络的一个重要课题，其主要目的是最大化频谱的使用率和效率，同时保证边缘小区的体验。基本的方法是尽可能使相邻的小区使用不同的频段，即正交的信道，然而，在无线局域网(英文全称为：Wireless Local Access Network，缩写为：WLAN)中，可用的正交信道有限，邻区将或多或少存在同频干扰，且加上WLAN特有的载波监听机制，将导致小区边缘的用户体验较差。Spectrum planning and optimization is an important issue in the network. Its main purpose is to maximize the utilization and efficiency of spectrum while ensuring the experience of edge cells. The basic method is to make adjacent cells use different frequency bands as much as possible, that is, orthogonal channels. However, in a wireless local area network (English full name: Wireless Local Access Network, abbreviated as: WLAN), the available orthogonal channels are limited. , there will be more or less co-channel interference in adjacent cells, and coupled with the unique carrier sense mechanism of WLAN, it will lead to poor user experience at the edge of the cell.

目前，WLAN使用的是工业、科学和医学(英文全称为：Industrial，Scientific andMedical，缩写为ISM)频段，容易受到外部干扰，加上用户终端负载的动态性，接入点(英文全称为：Access Point，缩写为：AP)的频谱优化的需求日益频繁，传统的频谱优化基于某一特定目标，如最大化系统容量，根据小区的负载情况对小区进行信道分配，可以适应业务的动态性。但这种方法不适应WLAN网络，因为最大化容量容易优先分配信道给离接入点较近的用户终端，没有考虑到WLAN中的小区边缘用户的体验。At present, WLAN uses the industrial, scientific and medical (English full name: Industrial, Scientific and Medical, abbreviated as ISM) frequency band, which is vulnerable to external interference, coupled with the dynamic nature of user terminal load, the access point (English full name: Access Point, abbreviated as: AP) spectrum optimization needs are becoming more and more frequent. Traditional spectrum optimization is based on a specific goal, such as maximizing system capacity, channel allocation to cells according to cell load conditions, and can adapt to service dynamics. However, this method is not suitable for WLAN networks, because maximizing capacity tends to preferentially allocate channels to user terminals that are closer to the access point, without considering the experience of cell edge users in WLAN.

在现有的技术中，系统可通过信道重用的方式，可极大的提高小区中心的容量，从而提高网络的容量，然而，用户终端的业务需求和移动的时变性，将使得网络的业务分步并不均价，简单的信道重用的方式并不能适应网络业务的变化，且由于WLAN使用的ISM频段，难以保证小区有所需要的正交信道，将进一步降低小区边缘用户的体验。因此，现有技术中的信道分配方式难以适应网络业务变化及满足小区边缘用户的体验。In the existing technology, the system can greatly increase the capacity of the cell center through channel reuse, thereby increasing the capacity of the network. The simple channel reuse method cannot adapt to changes in network services, and due to the ISM frequency band used by WLAN, it is difficult to ensure that the cell has the required orthogonal channel, which will further reduce the user experience at the cell edge. Therefore, it is difficult for the channel allocation method in the prior art to adapt to changes in network services and satisfy the experience of cell edge users.

在本发明实施例中，AC根据接收到的AP发送的基于AP的所有子区域的业务需求得到的业务需求满意度判断是否需要进行信道优化，其中，AC判断需要进行信道优化的方式有多种，例如：AC可计算接收到的其管理的AP发送的基于所有子区域的业务需求得到的业务需求满意度的平均值；判断该计算得到的业务需求满意度的平均值是否大于或等于预先设置的第一数值；若该平均值大于或等于预先设置的第一数值，则AC可确定不需要进行信道优化；若该平均值小于预先设置的第一数值，则AC可确定需要进行信道优化。举例为：若AC接收到其管理的5个AP发送的业务需求满意度，分别为0.7、0.8、0.75、0.85、0.7，则计算该5个AP的业务需求满意度的平均值，该平均值为0.76，若预先设置的第一数值为0.7，则可确定AC计算得到的业务需求满意度的平均值0.76大于预先设置的第一数值0.7，则不需要进行信道优化。又例如：AC将接收到的AP发送的基于所有子区域的业务需求得到的业务需求满意度分别与预先设置的第四数值进行比较，确定大于或等于预先设置的第四数值的AP发送的业务需求满意度的个数；并判断大于或等于预先设置的第四数值的AP的业务需求满意度的个数与AC接收到的业务需求满意度的个数的比值是否大于或等于预先设置的第五数值；若大于或等于第五数值，则AC可确定不需要进行信道优化；若小于该第五数值，则AC可确定需要进行信道优化。举例为：若AC接收到其管理的5个AP发送的业务需求满意度，分别为0.6、0.7、0.75、0.8、0.85，若预先设置的第四数值为0.75，则可确定大于或等于预先设置的第四数值0.75的业务需求满意度的个数为3，则3与5的比值为0.6，若预先设置的第五数值为0.7，则比值0.6小于预先设置的第五数值0.7，AC确定需要进行信道优化。In the embodiment of the present invention, the AC judges whether channel optimization needs to be performed according to the service demand satisfaction degree received from the AP based on the business demand of all sub-areas of the AP. There are many ways for the AC to judge the need for channel optimization. , for example: AC can calculate the average value of service requirement satisfaction received based on the service requirements of all sub-areas sent by the AP it manages; judge whether the calculated average value of service requirement satisfaction is greater than or equal to the preset If the average value is greater than or equal to the preset first value, the AC may determine that channel optimization is not required; if the average value is less than the preset first value, the AC may determine that channel optimization is required. For example: if the AC receives the business demand satisfaction levels sent by the 5 APs it manages, which are 0.7, 0.8, 0.75, 0.85, and 0.7, then calculate the average value of the business demand satisfaction levels of the 5 APs. is 0.76, if the preset first value is 0.7, it can be determined that the average value of service demand satisfaction calculated by the AC is 0.76 greater than the preset first value 0.7, and channel optimization is not required. Another example: the AC compares the received service demand satisfaction degree based on the service demand of all sub-areas sent by the AP with the preset fourth value, and determines that the service sent by the AP is greater than or equal to the preset fourth value The number of demand satisfaction; and judging whether the ratio of the number of service demand satisfaction of APs that are greater than or equal to the preset fourth value to the number of service demand satisfaction received by the AC is greater than or equal to the preset fourth value Five numerical values; if greater than or equal to the fifth numerical value, the AC may determine that channel optimization is not required; if less than the fifth numerical value, the AC may determine that channel optimization needs to be performed. For example: if the AC receives the business demand satisfaction levels sent by the five APs it manages, which are 0.6, 0.7, 0.75, 0.8, and 0.85, and if the preset fourth value is 0.75, it can be determined that it is greater than or equal to the preset The number of business demand satisfaction with the fourth value 0.75 is 3, then the ratio of 3 to 5 is 0.6, if the preset fifth value is 0.7, then the ratio 0.6 is smaller than the preset fifth value 0.7, AC determines the need Perform channel optimization.

204、若确定需要进行信道优化，则计算AC管理的每一个AP基于所有子区域的估计负载；204. If it is determined that channel optimization needs to be performed, calculate the estimated load of each AP managed by the AC based on all sub-areas;

在本发明实施例中，若AC确定需要进行信道优化，则AC将统计AC管理的每一个AP基于所有子区域的估计负载，若AC确定不需要进行信道优化，则将继续使用当前的信道配置方案。In the embodiment of the present invention, if the AC determines that channel optimization is required, the AC will count the estimated load of each AP managed by the AC based on all sub-areas, and if the AC determines that channel optimization is not required, the current channel configuration will continue to be used Program.

需要说明的是，在本发明实施例中的，在计算AP所有子区域所需的总传输时长所使用的T_c的计算公式的第一项考虑了相邻小区之间的信号干扰，第二项考虑了相邻小区传输域的干扰，因此，AC可综合考虑干扰域和传输域带来的负载增加，使得得到更加准确的估计负载，以便于AC能够有效的进行信道配置的优化。It should be noted that, in the embodiment of the present invention, the first item of the calculation formula of_Tc used in calculating the total transmission duration required by all sub-areas of the AP takes into account the signal interference between adjacent cells, and the second term The term takes into account the interference of the transmission domain of adjacent cells.

303、AC根据业务需求满意度判断是否需要进行信道优化，若是，则继续执行步骤304；303. The AC judges whether channel optimization needs to be performed according to the service demand satisfaction, and if so, proceeds to step 304;

在本发明实施例中，AC根据AP发送的基于AP的所有属于外区的子区域的业务需求得到的业务需求满意度判断是否需要进行信道优化，其中，AC判断需要进行信道优化的方式有多种，例如：AC可计算接收到的其管理的AP发送的基于AP的所有属于外区的子区域的业务需求得到的业务需求满意度的平均值；判断该计算得到的平均值是否大于或等于预先设置的第一数值；若该平均值大于或等于预先设置的第一数值，则AC可确定不需要进行信道优化；若该平均值小于预先设置的第一数值，则AC可确定需要进行信道优化。举例为：若AC接收到其管理的5个AP发送的业务需求满意度，分别为0.7、0.8、0.75、0.85、0.7，则计算该5个AP的业务需求满意度的平均值，该平均值为0.76，若预先设置的第一数值为0.7，则可确定AC计算得到的业务需求满意度的平均值0.76大于预先设置的第一数值0.7，则不需要进行信道优化。又例如：AC将接收到的AP发送的基于AP的所有属于外区的子区域的业务需求得到的业务需求满意度分别与预先设置的第四数值进行比较，确定大于或等于预先设置的第四数值的AP发送的业务需求满意度的个数；并判断大于或等于预先设置的第四数值的AP的业务需求满意度的个数与AC接收到的业务需求满意度的个数的比值是否大于或等于预先设置的第五数值；若大于或等于第五数值，则AC可确定不需要进行信道优化；若小于该第五数值，则AC可确定需要进行信道优化。举例为：若AC接收到其管理的5个AP发送的业务需求满意度，分别为0.6、0.7、0.75、0.8、0.85，若预先设置的第四数值为0.75，则可确定大于或等于预先设置的第四数值0.75的业务需求满意度的个数为3，则3与5的比值为0.6，若预先设置的第五数值为0.7，则比值0.6小于预先设置的第五数值0.7，AC确定需要进行信道优化。In the embodiment of the present invention, the AC judges whether channel optimization needs to be performed according to the satisfaction degree of service requirements sent by the AP based on the service requirements of all sub-areas belonging to the outer zone of the AP. Wherein, the AC determines how many channels need to be optimized For example: the AC can calculate the average value of service demand satisfaction received from the APs it manages, based on the service demands of all sub-areas belonging to the outer area of the AP; judge whether the calculated average value is greater than or equal to A preset first value; if the average value is greater than or equal to the preset first value, the AC can determine that channel optimization is not required; if the average value is less than the preset first value, the AC can determine that channel optimization needs to be performed optimization. For example: if the AC receives the business demand satisfaction levels sent by the 5 APs it manages, which are 0.7, 0.8, 0.75, 0.85, and 0.7, then calculate the average value of the business demand satisfaction levels of the 5 APs. is 0.76, if the preset first value is 0.7, it can be determined that the average value of service demand satisfaction calculated by the AC is 0.76 greater than the preset first value 0.7, and channel optimization is not required. Another example: the AC compares the service demand satisfaction degree received by the AP based on the service demands of all sub-areas belonging to the outer area of the AP with the preset fourth value, and determines that it is greater than or equal to the preset fourth value. The number of service demand satisfactions sent by the AP with a numerical value; and whether the ratio of the number of service demand satisfactions of APs that are greater than or equal to the preset fourth value to the number of service demand satisfactions received by the AC is greater than or equal to a preset fifth value; if greater than or equal to the fifth value, the AC may determine that channel optimization is not required; if less than the fifth value, the AC may determine that channel optimization is required. For example: if the AC receives the business demand satisfaction levels sent by the five APs it manages, which are 0.6, 0.7, 0.75, 0.8, and 0.85, and if the preset fourth value is 0.75, it can be determined that it is greater than or equal to the preset The number of business demand satisfaction with the fourth value 0.75 is 3, then the ratio of 3 to 5 is 0.6, if the preset fifth value is 0.7, then the ratio 0.6 is smaller than the preset fifth value 0.7, AC determines the need Perform channel optimization.

According to the obtained business demand satisfaction, and judge whether channel optimization is needed according to the business demand satisfaction, when it is determined that channel optimization needs to be performed, AC calculates all the sub-areas belonging to the outer area of each AP under its management. The ratio between the total transmission duration and the total transmission duration available to all sub-areas belonging to the outer area of the AP, the ratio is the estimated load of the corresponding AP, and the optional channel configuration scheme set is calculated according to the calculated estimated load.
