接入控制方法、装置和可读存储介质 技术领域
本公开涉及通信技术领域,尤其涉及一种接入控制方法、装置和可读存储介质。
背景技术
为了弥补有线局域网的不足,无线局域网(Wireless Local Area Networks,WLAN)应运而生。实际应用中,WLAN一般用于家庭、大楼内部以及园区内部的无线网络覆盖,目前采用的技术标准主要是802.11系列标准。通过利用无线技术在空中传输数据、话音和视频信号,WLAN使得功能日益强大的便携式数据终端以及多媒体终端能够接入无线网络。而在无线网络资源的管理中,接入控制是必不可少的。
在传统的无线局域网中,一般使用单接入点(AP,Access Point)提供数据传输的服务,该单AP无线局域网的覆盖范围一般为几米到十几米。因而在接入控制时,也是基于单AP而言。
然而,单AP的覆盖范围有限,对于大面积的WLAN应用场景,例如别墅或者展馆等,单AP的覆盖范围很难满足各种不同终端的数据传输需求。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
在对本公开实施例进行详细的解释说明之前,先对本公开实施例涉及的应用场景予以介绍。
下面以局域网,特别是依据IEEE802.11标准中提供的无线局域网标准的无线局域网为例,来说明本公开的一个可能的适用场景。需要说明的是,本公开的适用场景不限于以下举例,还适用于其他需要用到接入控制方案的场景。
在传统的无线局域网中,一般使用单AP提供数据传输的服务,但单AP的覆盖范围有限,对于大面积的场合,例如别墅等,可使用MAP来实现无线局域网的大面积覆盖。参见图1,其示出了一个本公开实施例提供的MAP场景示意图。
如图1所示,无线局域网通过MAP设备1与广域网连接,并通过MAP设备1、与MAP设备1连接的MAP设备2和MAP设备3、与MAP设备2连接的MAP设备4向无接入点工作站(Non Access Point Station,Non-AP STA)提供数据传输服务,Non-AP STA是接受无线局域网所提供的数据传输服务的终端。其中,MAP设备2中的回传站点(Backhaul Station,BH-STA)与MAP设备1的前传接入点(Fronthaul AP,FH-AP)通过Wi-Fi回传链路连接;MAP设备2中的FH-AP与Non-AP STA通过Wi-Fi前传链路连接;MAP设备3中的逻辑以太网接口(Logical Ethernet Port,LE-P)通过有线回传链路与MAP设备1中的 LE-P连接。图1中的其他设备连接情况与此类似,不再赘述。
图1所示无线局域网通过多个MAP设备向一个或者多个FH-AP、BH-STA或者工作站(Station,STA)提供服务,不同的FH-AP、BH-STA或者STA可能具有不同的数据传输需求,也即有不同的QoS需求,无线局域网需要根据不同的QoS需求提供不同的QoS策略,以保证数据传输的服务质量。例如,视频会议、语音电话和文件下载等。其中,视频会议和语音电话对QoS的时延要求相对较高,文件下载对QoS的时延要求相对较低。通信网络可以根据获取到的网络性能参数来评估实际传输中的QoS水平,进而调整QoS策略,以满足不同的数据传输类型对于QoS的要求。
根据不同QoS的要求,对数据传输按照业务的接入类型进行分类,分类方式可以有多种,例如,数据传输类型可以分类得到第一类型或者分类得到第二类型。例如,第一类型是AC类型,AC类型包含但不限于以下类别的一种或者多种:
AC_BK:背景类;
AC_BE:尽力而为类;
AC_VI:视频类;
AC_VO:语音类。
又例如,第二类型是UP类型。可选地,UP类型可以分为8种,序号是0-7,分别用UP0,UP1,UP2,UP3,UP4,UP5,UP6和UP7表示。
数据传输的不同的UP类型可以映射到不同的AC类型。在数据传输中,在MAC层将该数据传输的UP类型映射到AC类型,以使得该数据根据该AC类型加入相应的传输队列,并根据相应的接入参数进行传输。
示例性地,UP类型到AC类型的映射关系参见表1。如表1所示,UP1映射到AC_BK,AC_BK优先级是最低优先级;UP6映射到AC_VO,AC_VO优先级是最高优先级。表中其他映射关系与此类似,不再赘述。
表1
优先级 UP AC
最低优先级 1 AC_BK
  2 AC_BK
  0 AC_BE
  3 AC_BE
  4 AC_VI
  5 AC_VI
最高优先级 6 AC_VO
  7 AC_VO
下面对本公开实施例所提供的一种无线局域网的系统架构进行说明,参见图2,其示出了一种可选的MAP通信系统架构图,该MAP通信系统200包括:至少一个多AP控制 器(MAP-C,Multi-AP Controller)、至少一个多AP代理(MAP-A,Multi-AP Agent)、至少一个FH-AP和至少一个BH-STA。其中,虚线表示控制接口,实线表示数据接口。
MAP-C是MAP网络的逻辑控制实体,可以通过控制MAP-A来收集网络性能参数,并根据MAP-A汇报的网络性能参数优化MAP网络配置,提高数据传输的QoS。其中,MAP-C对MAP-A的控制通过向MAP-A发送控制消息实现,该控制消息中承载有用于指示MAP-A执行相关操作的控制信息。
MAP-A通过接收MAP-C的控制消息来获取控制信息,并根据控制信息来控制FH-AP和BH-STA,实现网络配置、网络性能参数收集等功能,进而提高数据传输的QoS。
FH-AP根据MAP-A的指令完成网络性能参数收集等功能。
其中,MAP-C可以通过有线或者无线两种通信方式与MAP-A相互通信,MAP-C的控制消息采用控制消息数据单元(Control Message Data Unit,CMDU)的形式进行单播传输,并由MAP-A获得。在一个CMDU中,可能包括多个消息。参见表2,其示出了CMDU中可能包括的消息及其描述。
