通过上述附图,已示出本公开明确的实施例,后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围,而是通过参考特定实施例为本领域技术人员说明本公开提到的概念。
具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,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清楚、完整的描述。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。基于本申请中的实施例,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。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例,能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含。例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
本申请下述各实施例提供的链路处理方法、装置、电子设备及存储介质,可应用于采用TDD技术的3G、4G或者WPAN等通信系统中多链路的网络拓扑结构中。该网络拓扑结构包含第一设备和两个及以上的第二设备,第一设备与第二设备之间通过独立链路通信连接,各设备之间可交换 数据,也可与网络设备如高层网络设备或互联网中的网络设备等进行连接。第一设备可连接有至少一个第二设备。在WPAN中,第一设备例如为手机、平板电脑等。第二设备例如可以为无线耳机、智能腕表或者其他数据传感器。在WPAN中,第一设备与每个第二设备之间可通过独立链路通信连接,该条链路上第一设备和该每个第二设备可通过无线保真(WIreless-Fidelity,简称WiFi)、红外数据组织(Infrared Data Association,简称IrDA)、蓝牙、低功耗蓝牙(Bluetooth Low Energy,简称BLE)、紫峰(Zigbee)等任一类型的无线传输技术进行传输。
在多连接应用场景下,一个维持多连接的设备,其各条链路之间可能会发生调度冲突,从而会导致链路的稳定性降低;根据实际应用需求,每条链路的数据压力也可能各有不同,设备需要根据不同链路的数据压力让传输压力较大的链路拥有更多带宽,从而提高带宽利用率和应用的整体表现。
本申请实施例所提供的链路处理方法,可通过对多连接锚点排布优化技术,第一设备可以在多条连接建立之后,根据各条链路的各项网络需求,合理排布各条链路的锚点,从而规划各条链路的带宽占空比,同时规避链路之间的调度冲突,最终能够给用户或者系统提供更好的网络服务和用户体验。
图1为本申请一应用场景的原理示意图,如图1所示,在包含第一设备和两个及以上的第二设备的网络中,可以使第一设备与第二设备的链路在一个间隔(Interval)中均匀或按比例排布,以减少调度冲突,让带宽需求更多的链路拥有更多比例的通信带宽,提高网络整体表现。例如,规划各条链路的带宽占空比,使得第二设备A占10%带宽、第二设备B占20%带宽、第二设备C占40%带宽、第二设备D占30%带宽,从而避免链路间的调度冲突,提高链路的稳定性。
图2为本申请另一应用场景的原理示意图,如图2所示,第一设备可以根据设备响应速度需求配置对连接的各个第二设备的响应延迟。例如,规划各条链路的响应延迟,使得第二设备A为4xT响应延迟、第二设备B为1xT响应延迟、第二设备C为2xT响应延迟、第二设备D为3xT响应延迟,从而避免链路间的调度冲突,提高链路的稳定性。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何 解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
图3为本申请实施例一提供的链路处理方法的流程图,如图3所示,本实施例中的方法可以应用在包含第一设备和两个及以上的第二设备的网络中,第一设备与第二设备之间通过独立链路通信连接,本实施例中的方法可以包括:
S101、第一设备向至少一个第二设备发送连接参数更新请求。
本实施例中,第一设备可以基于BLE5.0系列标准协议,通过特定的参数配置、特定的流程处理及第一设备参数应用,实现第一设备对其各条链路锚点的均匀或者成比例进行无冲突排布的连接层向。例如,第一设备的连接层可以向第二设备发送连接参数更新请求(LL_CONNECTION_PARAM_REQ PDU)。
需要说明的是,本实施例不限定拓扑结构中第一设备和第二设备的类型。在拓扑结构中可以第一设备是主设备、第二设备是从设备,也可以第一设备可以是从设备、第二设备是主设备,还可以第一设备是多角色设备、第二设备是主设备或从设备。
S102、在第二设备确认连接参数更新请求时,根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置。
本实施例中,在根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置之前,还包括:与第二设备通过链路的连接事件,协商确定瞬时参考点。例如,第一设备与第二设备按照CE配参协商,确定瞬时参考点Instant。
可选地,所有链路上的连接事件的长度之和,不大于各个链路中的最小连接间隔。
具体地,连接事件的长度表示连接事件在一个连接间隔(Connection Interval)之内的占位空间,因为全称为The Length Of Connection Event,简称为CE_LEN。本申请直接利用BLE5.1标准协议确定第一设备的CE_LEN,这里可以将BLE5.1规范Vol2.PartE 7.8.18LE Connection Update command小节,在发起连接参数更新时存在的两个参数Minimum_CE_Length和Maximum_CE_Length均配置为CE_LEN,从而确定本申请所提出的CE_LEN参数。第一设备作为链路的管理者,可以根据 各条链路的带宽需求、响应速度需求,为各条链路配置不同的CE_LEN以及成倍数关系的间隔(Interval),让带宽需求更大的链路占用更多的带宽,让响应速度需求更高的设备具有更小的Interval。假设第一设备作为主设备端依次与周围多个从设备建立连接事件A、B、C、D,第一设备会让各条链路的连接关系Connection Interval成倍数关系,此处将最小的Connection Interval记为Intv_Min,其他事件B、C、D的Interval与Intv_Min成倍数关系,第一设备会让几个事件相对参考点偏移进行偏移(记为Offset)。图4为本申请实施例多链路的连接间隔的示意图,如图4所示,第一设备在排布链路的过程中,算法设定各条链路的时序关系如下:
Step 1)记Event_A_Offset=0
Step 2)令Event_B_Offset=Event_A_Offset+CE_LEN_A
Step 3)令Event_C_Offset=Event_B_Offset+CE_LEN_B
Step 4)令Event_D_Offset=Event_C_Offset+CE_LEN_C
以上过程可以通过第一设备发起连接参数更新实现。算法限制条件:多条链路的CE_LEN之和不能大于最小的Interval,否则会出现带宽不足以及链路冲突的问题,无法达到链路排布优化的目的。
可选地,根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置,包括:以瞬时参考点为起点位置,将链路锚点向后移动一个窗口移动距离。
具体地,图5为本申请实施例多链路移动锚点的示意图,如图5所示,第一设备与第二设备通过协商的瞬时参考点Instant,计算合理的窗口移动距离WinOffset。然后第一设备与第二设备按照约定在同一个Instant位置向后移动WinOffset距离;其中,Old interval表示旧的连接间隔,New interval表示新的连接间隔。本实施例可以实现连接事件锚点的移动,之后的调度按照新的Interval周期性调度。
S103、根据链路锚点的移动位置,调整链路的连接参数。
本实施例中,根据链路锚点的移动位置,调整链路的连接参数,包括:从链路锚点的移动位置开始,调整链路的连接间隔和/或连接事件的带宽占空比。
可选地,调整链路的连接间隔,包括:根据各个链路的响应速度需求,调整各个链路的连接间隔;其中,各个链路的连接间隔相等,或者呈倍数关系。
具体地,可以通过连接参数更新配置第一条链路的连接间隔CE=Interval/2,第二条链路的连接间隔CE=Interval/2实现图6所示的均匀排布。此种情况下,链路1占据1/2的带宽,链路2占据1/2的带宽。也可以通过连接参数更新配置第一条链路的连接间隔Interval=CI,连接事件带宽占空比CE=CI/2,第二条链路的连接间隔Interval=2*CI,连接事件带宽占空比CE=CI/2实现图7所示的倍数关系排布。此种情况下,链路1将具备更快的响应速度,并且可以交替的占据全部带宽。
可选地,调整链路的连接事件的带宽占空比,包括:根据各个链路的带宽需求,调整各个链路的连接事件的带宽占空比;其中,各个链路的连接事件的长度相等,或者呈倍数关系。
具体地,可以通过连接参数更新配置第一条链路的连接间隔Interval=CI,连接事件的带宽占空比CE=3*CI/4,第二条链路的连接间隔Interval=CI,连接事件的带宽占空比CE=1*CI/4实现图8所示的比例关系排布。此种情况下,链路1占据3/4的带宽,链路2占据1/4的带宽。也可以通过连接参数更新配置第一条链路的连接间隔Interval=CI,连接事件的带宽占空比CE=CI/2,第二条链路的连接间隔Interval=2*CI,连接事件的带宽占空比CE=CI/4,第三条链路的连接间隔Interval=CI,连接事件的带宽占空比CE=CI/4实现图9所示的倍数关系排布。此种情况下,链路1、链路3将具备更快的响应速度,并且链路1可占据带宽范围为1/2到3/4倍Interval,链路3总是占据1/4的Interval。
本实施例,通过第一设备向至少一个第二设备发送连接参数更新请求;在第二设备确认连接参数更新请求时,根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置;根据链路锚点的移动位置,调整链路的连接参数。从而实现了对多链路的调度进行合理排布,避免链路间的调度冲突,提高链路的稳定性,以及优化各个链路的带宽占空比,提高带宽资源的利用率。
图10为本申请实施例二提供的链路处理方法的流程图,如图10所示,本实施例中的第一设备作为主设备,第二设备作为从设备,本实施例中的方法可以包括:
S201、第一设备向至少一个第二设备发送连接参数更新请求。
本实施例中,第一设备作为主设备,第二设备作为从设备,图11为本 申请实施例二提供的网络拓扑结构的示意图,如图11所示,由主设备发起,和众多从设备中的任意一个建立连接,用于应用数据交互,第一设备作为该条链路的主设备端,负责建立链路,且双方都可以更新链路参数、交互应用数据。在实现过程中,主设备向从设备发送连接参数更新请求,具体描述,可参照S101,此处不再赘述。
S202、接收第二设备反馈的连接参数更新确认信息。
本实施例中,从设备如果同意该请求并回复连接参数更新确认信息(LL_CONNECTION_PARAM_RSP PDU)。主设备接收从设备反馈的确认信息。
S203、根据连接参数更新请求中,连接事件的最小长度和连接事件的最大长度,确定窗口移动距离。
本实施例中,主设备根据连接更新参数中Minimum_CE_Length和Maximum_CE_Length确立的CE_LEN计算确定窗口移动距离WinOffset。例如,可以利用BLE5.1标准协议确定第一设备的CE_LEN,这里可以将BLE5.1规范Vol2.PartE 7.8.18 LE Connection Update command小节,在发起连接参数更新时存在的两个参数Minimum_CE_Length和Maximum_CE_Length均配置为CE_LEN,从而确定本申请所提出的CE_LEN参数。
S204、在第二设备确认连接参数更新请求时,根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置。
S205、根据链路锚点的移动位置,调整链路的连接参数。
本实施例中,步骤S204、步骤S205的具体实现过程和技术原理请参见图3所示的方法中步骤S102、步骤S103中的相关描述,此处不再赘述。
S206、将窗口移动距离添加在连接参数更新通知包中,并将连接参数更新通知包发送给第二设备。
本实施例中,还可以将窗口移动距离添加在连接参数更新通知包中,并将连接参数更新通知包发送给第二设备,由第二设备调整链路的连接参数。
需要说明的是,本实施例中第一设备作为主设备时,因最终的窗口移动距离Winoffset由主设备决定,即该链路锚点调整技术应用于主设备一般可兼容其他BLE5.0设备。
本实施例,通过第一设备向至少一个第二设备发送连接参数更新请求;在第二设备确认连接参数更新请求时,根据瞬时参考点和窗口移动距离,确定链路锚点的移动位置;根据链路锚点的移动位置,调整链路的连接参数。从而实现了对多链路的调度进行合理排布,避免链路间的调度冲突,提高链路的稳定性,以及优化各个链路的带宽占空比,提高带宽资源的利用率。
另外,本实施例中的第一设备作为主设备,第二设备作为从设备。还可以接收第二设备反馈的连接参数更新确认信息;根据连接参数更新请求中,连接事件的最小长度和连接事件的最大长度,确定窗口移动距离;将窗口移动距离添加在连接参数更新通知包中,并将连接参数更新通知包发送给第二设备。从而实现了对多链路的调度进行合理排布,避免链路间的调度冲突,提高链路的稳定性,以及优化各个链路的带宽占空比,提高带宽资源的利用率。
图12为本申请实施例三提供的链路处理方法的流程图,如图12所示,本实施例中的第一设备作为从设备,第二设备作为主设备,本实施例中的方法可以包括:
