Description

无线通信方法及设备
优先权信息
本申请要求OPPO广东移动通信有限公司于2020年04月09日提交的，申请名称为“无线通信方法及设备”的、中国专利申请号“2021103853896”的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种无线通信方法及设备。
背景技术
在标准802.11bc中，站点(Station，STA)通过接入网查询协议(Access Network Query Protocol，ANQP)请求(Request)和ANQP响应(Response)，或者，通过增强广播服务(Enhanced Broadcast Service，eBCS)请求(Request)和eBCS响应(Response)方式快速发现(即快速获取)eBCS。然而，目前ANQP响应中的增强广播响应ANQP元素结构中并不存在eBCS的认证信息，同样的，目前eBCS响应中的eBCS响应元素结构中也不存在eBCS的认证信息。因此，STA无法通过ANQP请求和ANQP响应、eBCS请求和eBCS响应方式获得eBCS的认证信息，而是必须等待接收到eBCS信息(Info)帧之后才能获得eBCS的认证信息。
然而，eBCS信息帧发送周期较大，发送间隔是目标信标传输时间(Target Beacon Transmission Time，TBTTs)。此时，针对公钥帧身份认证(Public Key Frame Authentication，PKFA)认证的eBCS，等待eBCS信息帧提供的认证信息会增加PKFA MAC协议数据单元(MAC Protocol Data Unit，MPDU)的认证时延，无法满足PKFA对时延敏感数据认证需求；针对不进行立即认证的哈希链帧身份认证(Hash Chain Frame Authentication，HCFA)(HCFA Without Instant Authentication)，等待eBCS信息帧提供的认证信息会增加HCFA MPDU的认证时延，无法满足不进行立即认证的HCFA用于连续内容分发(实时流式传输或定期文件传输)的目标；针对进行立即认证的HCFA(HCFA With Instant Authentication)，等待eBCS信息帧过程中由于会引入很大时延，会导致STA丢弃已经接收到的HCFA MPDU，造成数据浪费。总之，现有技术存在eBCS获取过程中的数据认证时延较大、eBCS认证延时导致的数据丢失问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在介绍本申请技术方案之前，下面将对本申请相关知识进行阐述：
IEEE802.11bc提供了一种下行增强广播服务(Enhanced Broadcast Service DownLink，eBCS DL),用于实现接入点(Access Point，AP)向STA广播数据。
应理解的是，本申请中的AP也被称为eBCS AP，STA也被称为eBCS non-AP STA，本申请对此不做限制。
在eBCS DL流程中，AP会周期性广播eBCS信息帧，以实现eBCS DL服务发现并提供eBCS(即eBCS数据)的认证(Authentication)信息。本方案主要改进了eBCS DL流程中的eBCS快速获取服务，完善了终止通知过程的协商流程。
图1提供了一种eBCS DL流程示意图。如图1所示，具体流程包括：
(1)在扫描阶段，AP发送信标(Beacon)帧或者探测响应(Probe Response)帧，该信标帧或者探测响应帧携带关于下一次eBCS信息帧(Next eBCS Info frame)的字段，以告知STA下一次eBCS信息帧的广播时间。
(2)STA在指定时间接收到eBCS信息帧后，就获得了eBCS数据(data)帧的发送时间和认证信息。因此，STA在指定时间接收AP广播的eBCS数据帧，从而获取eBCS。
应理解的是，本申请中的eBCS数据帧也被称为eBCS或者eBCS数据，本申请对此不做限制。
(3)除了上述STA被动获取eBCS以外，eBCS DL流程还支持STA发送ANQP请求或者eBCS请求来主动请求一个或多个eBCS服务，以达到快速发现eBCS的目的。针对需要注册但不需要关联的eBCS，STA通过ANQP请求和ANQP响应帧完成eBCS服务快速发现，从而获得eBCS的发送时间；针对需要关联的eBCS服务，STA通过eBCS请求和eBCS响应帧完成eBCS服务快速发现，从而获得eBCS数据的发送时间。图2为ANQP响应中的增强广播响应ANQP元素结构(Enhanced Broadcast Response ANQP-element)的示意图，图3为eBCS响应中的eBCS响应元素结构(eBCS Response element)的示意图，如图2和图3所示，增强广播响应ANQP元素结构和eBCS响应元素结构中均未包含eBCS数据的认证信息。
(4)因此，STA在获取eBCS数据帧后，必须要等待eBCS信息帧获得eBCS数据帧的认证信息。
进一步的，在STA接收到eBCS数据帧后，针对不同eBCS数据认证方式，采用不同方式的数据认证流程，具体分为以下3种：
a)若为PKFA认证，则STA需要等待接收eBCS信息帧。然后，从eBCS信息帧中缓存AP的证书(Certificate)，以认证eBCS数据，这种情况下，该eBCS数据也被称为PKFA MPDU。PKFA主要适用于偶尔的小数据传输或对时间敏感的数据传输。
b)若为不进行立即认证的HCFA，则STA需要等待接收eBCS信息帧，从eBCS信息帧中提取eBCS信息帧间隔(eBCS Info Interval)、HCFA基础密钥(HCFA Base Key)、HCFA密钥改变间隔(HCFA Key Change Interval)信息，并且提取后续eBCS数据中公布的HCFA基础密钥等信息，以认证eBCS数据，这种情况下，该eBCS数据也被称为HCFA MPDU。
c)若为进行立即认证的HCFA，则STA需要等待接收eBCS信息帧，从eBCS信息帧中提取立即认证器的数量(Number Of Instant Authenticators)、立即认证器的哈希距离(Instant Authenticator Hash Distance)和立即认证器(Instant Authenticator)信息，以认证eBCS数据，这种情况下，该eBCS数据也被称为HCFA MPDU。需要注意的是，针对HCFA认证的eBCS数据，在接收到eBCS信息帧之前，由于STA没有获得eBCS数据的认证信息，因此，STA会丢弃接收到的eBCS数据。
图4为eBCS信息帧的结构示意图，如图4所示，在eBCS信息帧中包含了有关eBCS的重要信息，主要分为时间维度信息和认证维度信息。其中，时间维度信息包括eBCS信息帧间隔(eBCS Info Interval)和每个内容(Content)标识(Identity，ID)所标识的eBCS对应的下一次数据帧传输的时间(Next Schedule)。认证维度信息包括认证证书(Certificate)、HCFA基础密钥(HCFA Base Key)、HCFA密钥改变间隔(HCFA Key Change Interval)信息等。
现有802.11bc标准下,针对不同认证方式的eBCS快速发现过程如下：
(一)采取PKFA认证方式的eBCS快速发现过程
图5是采取PKFA认证方式的eBCS快速发现时序图，如图5所示，当STA在图5所示的时间点加入现有通信网络。因为eBCS信息帧发送周期很大，发送间隔是TBTTs，则假设此时的STA错过了图中的第一个eBCS信息帧，它无法获取eBCS信息帧里有关PKFA认证的信息。针对需要注册但不需要关联的eBCS，STA通过ANQP请求/ANQP响应帧完成eBCS服务快速发现，从而获得PKFA MPDU的发送时间；针对需要关联的eBCS，STA在完成关联后通过eBCS请求和eBCS响应帧完成eBCS服务快速发现，从而获得PKFA MPDU发送时间。具体流程如下：
(1)STA接收信标帧或探测响应帧，通过帧中的关于下一次eBCS信息帧(Next eBCS Info frame)的字段，以告知STA下一次eBCS信息帧的广播时间。
(2)STA通过ANQP请求和ANQP响应帧、eBCS请求和eBCS响应帧完成eBCS快速发现，从而获得PKFA MPDU发送时间。但是，ANQP响应或者eBCS响应中不存在PKFA MPDU的认证信息，因此，即使STA能接收到PKFA MPDU，但它无法对PKFA MPDU进行认证。假设第二个eBCS信息帧的证书在有限期内，则STA缓存PKFA MPDU，等待第二个eBCS信息帧的到来。
(3)STA接收到第二个eBCS Info帧时，获取PKFA MPDU的发送时间和认证信息，并缓存认证信息，利用缓存的认证信息对PKFA MPDU进行验证。验证成功后，从而获得eBCS。
图6是采取HCFA认证方式的服务快速发现时序图，当STA在图6所示的时间点加入现有通信网络，因为eBCS信息帧发送周期很大，发送间隔是TBTTs，则假设此时的STA错过了第一个eBCS信息帧，它无法获取eBCS信息帧里有关HCFA认证的信息。针对需要注册但不需要关联的eBCS，STA通过ANQP请求和ANQP响应帧完成eBCS快速发现，从而获得HCFA MPDU的发送时间；针对需要关联的eBCS，STA在完成关 联后通过eBCS请求和eBCS响应帧完成eBCS快速发现，从而获得HCFA MPDU发送时间。具体流程如下：
(1)STA接收信标帧或探测响应帧，通过帧中的关于下一次eBCS信息帧(Next eBCS Info frame)的字段，以告知STA下一次eBCS信息帧的广播时间。
(2)STA通过ANQP请求和ANQP响应，或者，通过eBCS请求和eBCS响应方式完成eBCS快速发现，从而获得HCFA MPDU的发送时间。但是，ANQP响应或者eBCS响应中不存在HCFA认证的信息，因此，即使STA能接收到HCFA MPDU，但它无法对HCFA MPDU进行认证。所以在没接收到eBCS信息帧前，STA都要丢弃HCFA MPDU，等待第二个eBCS信息帧的到来。
(3)当STA接收到第二个eBCS信息帧时，获取HCFA MPDU的时间信息和认证信息。并且根据eBCS信息帧里指示的下一次数据帧传输的时间(Next Schedule)，STA在相应的时间点等待HCFA MPDU的到来。
(4)当STA接收到HCFA MPDU时，由于验证该HCFA MPDU的密钥未公开，所以STA缓存HCFA MPDU，等待HCFA MPDU对应的密钥公开。HCFA算法是一种密钥延时公开的算法，假设的密钥公开时间相对于HCFA MPDU接收的时间延迟如图6所示。当在假设的时间点获取到公开的密钥后，STA再根据时间标尺去认证之前缓存下来的HCFA MPDU。其中，密钥延迟公开最晚的时间点是当接收到第三个eBCS信息帧时，因为此时密钥信息包含在了这个eBCS信息帧的字段里。验证成功后，从而获得eBCS。
终止通知过程的协商技术方案
参照802.11bc描述的终止通知过程，当发送端即将要终止某项eBCS时，其协商的具体流程如图7所示：
应理解的是，该发送端是广播数据的设备，该发送端可以是STA，对应的，接收端可以是AP。或者，该发送端可以是AP，对应的，接收端可以是STA，本申请对此不做限制。
图7为终止通知过程协商流程图，如图7所示，
(1)当某项eBCS即将在小于或等于协议规定的eBCS终止通知时间(eBCS Termination Notice Time)的时间间隔内终止，则发送端会发送eBCS终止通知(eBCS Termination Notice)帧，以告知接收端这项eBCS的预期终止时间。另外，eBCS终止通知帧中除了指示这项eBCS特有的内容(Content)ID对应的eBCS终止时间(Time To Termination)，还指示了后续如果需要进行eBCS扩展的扩展信息，包括服务地址(Destination Address)、服务延长请求方式(Request Method)，图8为eBCS终止通知帧的结构示意图，如图8所示。
(2)如果eBCS终止通知帧中指示的eBCS预期终止时间对于接收端是能接受的，则这项eBCS将严格按照预期终止时间终止，其中，对于接收端而言，其能接受的终止时间不在802.11bc标准中做规定。如果eBCS终止通知帧中指示的eBCS预期终止时间比接收端实际预期终止的时间早，则接收端将根据接收到的eBCS终止通知帧指示的eBCS扩展信息，请求eBCS的延长。其中，eBCS延长请求方式(Request Method)可采取eBCS请求或者ANQP请求两种方式。
(3)针对需要注册和关联的eBCS，接收端发送携带有请求终止时间(Requested Time to Termination)的eBCS请求，以请求eBCS延长成功后，发送端将在eBCS响应中携带终止时间(Time to Termination)，以向接收端回复新的eBCS终止时间，如图9和图10所示。
(4)针对仅需注册，不需要关联的eBCS，接收端发送包含增强广播请求ANQP元素结构的ANQP请求，请求eBCS延长成功后，发送端将在ANQP响应包含的增强广播服务ANQP元素结构中携带终止时间，以向接收端回复新的eBCS终止时间，如图11、12所示。但是，在图11中，增强广播请求ANQP元素结构中没有终止时间的相关字段， 所以无法对新的eBCS终止时间进行请求和协商，实现不了eBCS扩展的目的。
对于需要注册和关联的eBCS终止通知过程的协商，具体的协商时序图如图13所示：
S1301：发送端确定要终止eBCS。
可选的，该终止eBCS包括：媒体接入控制(Media Access Control，MAC)广播终止，应用层可能仍然产生数据源的情况。
S1302：发送端生成终止通知帧。
S1303：发送端向接收端发送终止通知帧。
S1304：接收端从终止通知帧中获取内容标识对应的eBCS终止时间(Time To Termination)、服务地址(Destination Address)、服务延长请求方式(Request Method)。
S1305：接收端如果确定eBCS终止通知帧中指示的eBCS预期终止时间对于接收端是能接受的，则这项eBCS将严格按照预期终止时间终止。
S1306：如果eBCS终止通知帧中指示的eBCS预期终止时间比接收端实际预期终止的时间早，则接收端生成eBCS请求(Request frame)。
S1307：接收端将eBCS请求发送给发送端。
该eBCS请求包括：eBCS对应的内容标识(content ID)以及请求终止时间(Request time to termination)。可选的，eBCS请求包括：eBCS请求信息集合(eBCS Request Information Set)，该eBCS请求信息集合包括请求终止时间。
S1308：发送端接收到eBCS请求后，从eBCS请求中解析请求终止时间(Request time to termination)，使得发送端获取到了最新请求的eBCS终止时间。
S1309：发送端生成eBCS响应(eBCS Response frame)。
S1310：发送端将eBCS响应发送给接收端。
eBCS响应包括eBCS对应的内容标识(content ID)、终止时间(Time to Termination)、服务过程(Service Process)时长(duration)、SP间隔时间(interval)。可选的，eBCS响应包括eBCS响应信息集合(eBCS Response information set)，该eBCS响应信息集合包括终止时间(Time to Termination)。
S1311：接收端接收到eBCS响应后，从eBCS响应中解析终止时间(Time to Termination)，以获取协商后的eBCS终止时间。
本申请主要解决如下两个技术问题：
1、如上所述，在标准802.11bc中，STA通过ANQP请求和ANQP响应，或者，通过eBCS请求和eBCS响应方式快速发现eBCS。然而，目前ANQP响应中的增强广播响应ANQP元素结构中并不存在eBCS的认证信息，同样的，目前eBCS响应中的eBCS响应元素结构中也不存在eBCS的认证信息。因此，STA无法通过ANQP请求/ANQP响应、eBCS请求和eBCS响应方式获得eBCS的认证信息，而是必须等待接收到eBCS信息(Info)帧之后才能获得eBCS的认证信息，导致在eBCS获取过程中的数据认证时延较大、eBCS认证延时导致的数据丢失问题。
2、针对仅需注册的eBCS，在发送端发送eBCS终止通知帧给接收端后，如果eBCS终止通知帧中指示的eBCS预期终止时间比接收端实际预期终止的时间早，则接收端将根据接收到的eBCS终止通知帧指示的eBCS扩展信息，采取ANQP请求方式请求eBCS的延长。但当前的增强广播请求ANQP元素结构中没有服务终止时间字段。因此，该元素结构无法支持仅需注册的eBCS终止通知过程。
针对上述第1个技术问题，本申请主要采用如下方式来解决该技术问题：修改增强广播响应ANQP元素结构，或者修改增强广播请求ANQP元素结构和修改增强广播响应ANQP元素结构，或者，修改eBCS响应元素结构，或者，修改eBCS请求元素结构和eBCS响应元素结构。
针对上述第2个技术问题，本申请主要采用如下方式来解决该技术问题：修改增强广播请求ANQP元素结构。

综上，在本申请中，可以修改增强广播响应ANQP元素结构，或者修改增强广播请求ANQP元素结构和修改增强广播响应ANQP元素结构，或者，修改eBCS响应元素结构，或者，修改eBCS请求元素结构和eBCS响应元素结构，从而降低eBCS获取过程中的数据认证时延、缓解eBCS认证延时导致的数据丢失问题。
下面将对采取PKFA认证方式的eBCS快速获取过程进行说明：
在802.11bc中，eBCS DL支持关联的和非关联的eBCS。考虑到STA利用ANQP请求和ANQP响应，或者，eBCS请求和eBCS响应方式快速发现eBCS。针对PKFA认证方式，本申请在ANQP响应或者eBCS响应中新增了eBCS的认证信息，实现了PKFA认证的eBCS快速获取。图23是本申请实施例提供的PKFA方式的快速获取eBCS时序图，具体流程如下：
(1)在扫描阶段，在图23中时间点STA通过接收信标帧或探测响应帧加入现有通信网络。因为eBCS信息帧发送周期很大，发送间隔是TBTTs，则假设此时的STA错过了第一个eBCS信息帧。
(2)STA根据是否需要关联的条件，采取ANQP请求或eBCS请求方式请求快速获取所需服务内容。其中，针对需要注册但不需要关联的eBCS，STA通过ANQP请求和AN响应完成eBCS快速获取，从而获得PKFA MPDU发送时间和认证信息；针对需要关联的eBCS，STA在关联后通过eBCS请求和eBCS响应完成eBCS服务快速获取，从而获得PKFA MPDU发送时间和认证信息。
(3)当STA接收到ANQP响应或eBCS响应后，获得PKFA MPDU的发送时间和认证信息，并将认证信息缓存。
(4)最后，STA在指定时间接收到PKFA MPDU，并利用缓存的认证信息认证PKFA  MPDU的完整性。
综上所述，PKFA认证的eBCS快速获取时序图如图23所示。通过对比图5和图23可知，在PKFA认证方式下，如果采取本申请提供的快速服务获取方式，一方面节省了STA获取eBCS的时间，另一方面也提高了PKFA MPDU的利用率。
下面将对采取HCFA认证方式的eBCS快速获取过程进行说明：
如上所述，在802.11bc的eBCS DL中，在HCFA认证方式下，STA必须等待eBCS信息帧获取HCFA认证的信息(即eBCS的认证信息)。本申请在ANQP响应或者eBCS响应中新增HCFA认证的信息，实现了HCFA认证的eBCS快速获取。图24是本申请实施例提供的HCFA方式的快速获取eBCS时序图，具体流程如下：
(1)在扫描阶段，在如图24所示的时间点，STA通过接收信标帧或探测响应帧加入现有通信网络。因为eBCS信息帧发送周期很大，发送间隔是TBTTs，则假设此时的STA错过了第一个eBCS信息帧。
(2)STA根据是否需要关联的条件，采取ANQP请求或eBCS请求方式请求快速获取所需服务内容。其中，针对需要注册但不需要关联的eBCS，STA通过ANQP请求和ANQP响应完成eBCS快速获取，从而获得HCFA MPDU发送时间和认证信息；针对需要关联的eBCS，STA在关联后通过eBCS请求和eBCS响应完成eBCS服务快速获取，从而获得HCFA MPDU发送时间和认证信息。
(3)针对不进行立即认证的HCFA的eBCS，在ANQP响应或eBCS响应中新增设eBCS信息帧间隔(eBCS Info Interval)、HCFA密钥改变间隔(HCFA Key Change Interval)、HCFA基础密钥(HCFA Base Key)这三个字段的信息。针对进行立即认证的HCFA认证的eBCS，在ANQP响应或eBCS响应中新增设立即认证器的数量(Number Of Instant Authenticators)、立即认证器的哈希距离(Instant Authenticator Hash Distance)和立即认证器(Instant Authenticator)这三个字段的信息。当STA接收到ANQP响应或eBCS响应后，获得HCFA MPDU的发送时间和认证信息，将认证信息缓存并等待接收HCFA MPDU。
(4)STA接收到HCFA MPDU，由于已获取到HCFA认证的信息，则缓存HCFA MPDU，等待每个HCFA MPDU对应的密钥公开。HCFA是采用密钥的延时公开方式，假设DL eBCS1的HCFA MPDU密钥公开的时间如图24所示，STA在假设的时间点获取到公开的密钥后，根据时间标尺去认证之前缓存下来的HCFA MPDU。其中，密钥延迟公开最晚的时间点是当接收到图中第二个eBCS信息帧时，此时HCFA MPDU密钥信息包含在了这个eBCS信息帧的字段里。
综上所述，针对HCFA认证的eBCS快速获取时序图如图24所示。通过对比图6和图24可知，针对HCFA认证方式下，如果采取本本申请提供的快速服务发现的这种方式，一方面节省了STA获取eBCS服务的时间，另一方面也提高了HCFA MPDU的利用率。
图25为本申请实施例提供的另一种无线通信方法的交互流程图，如图25所示，该方法包括如下流程：

可选的，增强广播服务请求控制字段剩余部分为预留字段。
可选的，增强广播服务请求控制字段还包括：请求认证信息(Request Authentication Info)，用于STA的eBCS快速获取。

可选的，如图26所示，增强广播服务请求元组可以包括目标AP基本服务集标识(Target AP BSSID)。
示例2，图27为本申请实施例提供的另一种增强广播请求ANQP元素结构的示意图，如图27所示，在增强广播请求ANQP元素结构中，不额外增加增强广播服务请求控制字段和请求终止时间指示，默认在增强广播请求ANQP元素结构中携带请求终止时间。
示例3，图28为本申请实施例提供的另一种增强广播请求ANQP元素结构的示意图，如图28所示，在增强广播请求ANQP元素结构中，不额外增加增强广播服务请求控制字段，而是利用增强广播请求ANQP元素结构的其它预留字段，如广播行动字段下的预留字段增加请求终止时间指示。
需要说明的是，上述示例1至示例3仅仅是修改增强广播请求ANQP元素结构的几种示例，但不限于此。并且关于增强广播请求ANQP元素结构中各个字段的长度不限于图26和图28所示的字段长度。
