Description

一种数据传输控制方法,及网络设备 技术领域
本发明涉及通信技术领域,特别涉及一种数据传输控制方法,及网络设备。
背景技术
随着无线通信技术的飞速发展,无线用户数量的急剧增长,以及高清晰多媒体流业务的快速涌现,无线频谱资源越来越稀缺,但与此同时,用户对网络的速率及网络覆盖连续性的要求越来越高,这使得日益增长的无线需求与昂贵有限的授权频谱之间的矛盾日益凸显。因此,如何获取额外可用的频谱资源对运营商来说变得十分重要。为了缓解授权网络的压力,运营商开始考虑利用资源相对丰富的非授权频段来应对上述挑战。目前,许多运营商已通过在非授权频谱上部署无线局域网(Wireless Local Area Network,WLAN)网络来减轻移动网络的负担、分流无线业务。
但是随着WLAN网络部署的越来越密集,WLAN的缺陷越来越明显,比如:载波检测多址(carrier sense multiple access,CSMA)/信道分配(Channel Assignment,CA)机制导致密集部署场景下传输效率低下、不能保证业务的服务质量(Quality of Service,QoS)、不能提供良好的移动性支持等;而且,在某些临近运营商授权频段的频率资源附近,还会受到工作在授权频段的蜂窝通信系统的干扰。
为了解决上述这些问题,在2012年7月份的电子电气工程师协会(Institute of Electrical and Electronics Engineers,IEEE)802.11第134次会议上,有建议进一步研究如何提高下一代WLAN工作效率的提案。其中有建议进一步研究如何高效的通过运营商部署的WLAN网络为运营商的蜂窝网络进行流量卸载的文稿,成为了日后802.11ax标准工作小组成立的基础。该文稿指出,为了应对迅猛增长的流量需求,运营商需要将网络部署的更加密集,因此需要引入更多的热点来增加网络容量,这其中就 包括在室内室外密集部署大量的WLAN热点。
鉴于各厂商对该研究方向的持续广泛关注,也为了对该研究方向展开更加系统、深入的研究,IEEE 802.11在2013年5月正式成立一个独立的研究小组,主要研究目的包括如何提高下一代WLAN网络的频谱效率、区域吞吐量以及如何提高真实的室内和室外部署场景中WLAN网络的性能。
在2014年1月份的IEEE 802.11第143次会议上,重新命名了802.11ax,并且在2014年3月份的IEEE 802.11第144次会议上,该命名正式批准。在非授权频段附近蜂窝系统与WLAN系统的相互干扰也是802.11ax需要研究的问题之一。目前,消除相互干扰的方案采用的是对WLAN设备射频器件接收机增加阻塞干扰,这样会导致WLAN设备成本的增加。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部份实施例,而不是全部的实施例。基于本发明中的实施例,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它实施例,都属于本发明保护的范围。
如图1A、图1B以及图1C所示,为三个系统架构示意图,示意为本发明实施例的两个应用场景。其中包括LTE的基站,无线局域网WLAN的接入点(Access Point,AP);工作于LTE网络的LTE用户设备(User Equipment,UE),工作于无线局域网的端站WLAN STA;在图1A和图1B中,实线部分示意为承载数据/信号的通信连接,虚线部分是干扰的信号,在图1A和图1B中分别进行了1~4的编号;
如图1D所示,为本发明实施例基于以上系统架构的干扰分析,LTE网络在2.4GHz频带附近,分时长期演进(Time Division Long Term Evolution,TD-LTE)系统与无线局域网(Wireless Local Area Network,WLAN)系统的频带间距较近,因此,二者之间存在邻频干扰共存问题。
其中,在LTE对应的授权频段,是IMT(室内使用TDD模式,TDD  mode for indoor usage)对应的频段,时分复用(Time Division Duplex,TDD);无线局域网对应的非授权频段,则是,WLAN&其他工业科学(Industrial Scientific Medica,ISM)对应的频段。前者频段大致在2300~2400MHz,或者在2400~2483.5MHz,两者十分接近。
总体来讲,在2.4GHz附近,会存在两种形式的干扰:
第一种干扰为WLAN AP下行发射对TD-LTE eNB上行接收的干扰;
第二种干扰为TD-LTE eNB下行发射对WLAN AP上行接收的干扰。
根据实际测试结果,第二种干扰(TD LTE eNB->WLAN AP)要比第一种干扰(WLAN AP->TD LTE eNB)严重的多。
目前,不管TD LTE还是WLAN都没有机制来解决这个问题。因此,在TD LTE eNB下行发射时,WLAN AP将受到严重的干扰而无法避免,降低WLAN网络的传输效率。
本发明实施例要提出如何使LTE与WLAN在802.11ax系统中更好的进行共存的技术方案。
在本发明实施例中,当WLAN AP的上行接收受到TD LTE eNB下行发射的干扰时,WLAN AP主动通知TD LTE eNB自己受到的干扰情况;TD LTE eNB在收到WLAN AP的干扰通知后,可以配置一个时分复用(Time Division Multiplex,TDM)模式(pattern),该TDM pattern可以由LTE开启(ON)和LTE关闭(OFF)两个时间段组成,并将该TDM pattern告知WLAN AP。该TDM pattern可以直接通过WLAN AP与TD LTE eNB间的接口进行交互传输,也可以通过与TD LTE eNB和WLAN AP均建立有通信连接的UE的测量和上报协助进行交互传输。WLAN AP在收到该TDM pattern后,可以通过修改的信标(Beacon)告知与其连接的WLAN端站(Station,STA)上述TDM pattern。在LTE OFF时间段,WLAN STA可以发送数据给WLAN AP以免受TD LTE eNB的干扰。
在以上技术说明中,通过修改的Beacon携带了TDM pattern的信息,Beacon可以是一个全新的Beacon,也可以是在终端的接入流程或者数据 传输流程中已有的Beacon内增加TDM pattern的信息;新创建的Beacon可以参考一般Beacon的创建方式,但需要注意的是,其和一般Beacon相比,区别在于其携带的信息已包括TDM pattern的信息;若采用在已有的Beacon内增加TDM pattern的信息,那么可以是新增字段进行增加,也可以是在其已有的扩展字段增加,具体如何增加按具体需求(如:信息字段长度、兼容性等要求)进行确定,本发明实施例对此不作唯一性限定。通过上述的Beacon的修改方式,不但可以保持和原有的系统兼容,还能够实现新的功能的扩展。
基于以上介绍,本发明实施例提供了一种数据传输控制方法,如图2,包括:
201:第一网络设备确定受到第二网络设备的干扰后,向上述第二网络设备发送干扰告知信息;上述第一网络设备工作于非授权频段,上述第二网络设备工作于授权频段;
在本发明实施例中“第一”和“第二”用于区分两种不同的网络设备,不应理解为具有其他技术含义。非授权频段可以是例如:WIFI、蓝牙、紫峰等无线传输方式对应的不需要授权的无线传输频段;授权频段可以是3G,LTE等无线传输方式对应的需要授权的无线传输频段。第一网络设备通常来说可以是WLAN的接入点,第二网络设备则可以是授权接入频段对应的通信系统,例如:LTE的基站或者基站控制器等网络设备。本发明实施例中所称的工作于某一频段是指使用该频段的无线资源进行数据/信令等的通信。干扰告知信息通常需要携带受干扰的频段的指示信息,具体采用的形式可以是某一频段,然后标识为干扰状态;也可以是例如:受干扰信道的信噪比(Signal to Interference plus Noise Ratio,SINR)、受干扰信道的子带误码率、受干扰的频段信息以及受干扰的指示标识(可以在终端设备检测到自身受到干扰后发送)、还可以是包含干扰源/干扰程度/干扰频段等参数的信息(终端设备通过测量在其工作频段的信道中的多余信号,通过多余信号可以获知信号的传输时间、出现次数、载波频率和带宽,甚至是干扰发射机的物理位置等信息)等,只要能告知第二网络设备, 自身的某频段受到了干扰就可以了,具体的表现形式本发明实施例不作唯一性限定,但需要特别说明的是,实验表明,采用受干扰信道的信噪比(Signal to Interference plus Noise Ratio,SINR)、受干扰信道的子带误码率作为受干扰程度的考量具有较好的实际效果。第一网络设备和第二网络设备需要传递上述干扰告知信息,具体传递方式依不同的网络架构和对应的通信协议会有所区别,具体的传递方式可以据此选择,本实施例对此不作唯一性限定。
202:上述第一网络设备接收上述第二网络设备返回的决策信息;
本实施例中,决策信息会用于指导第一网络设备进行非授权频段的数据/信令传输,那么决策信息应当包含告知第一网络设备如何避免第一网络设备与第二网络设备在已经受干扰的频段继续干扰的信息。至于具体是何种信息,后续实施例将进行具体的说明。
203:上述第一网络设备按照上述决策信息与上述第二网络设备以时分复用的方式使用受干扰的频段。
基于本发明实施例中使用的时分复用的方式避免第一网络设备和第二网络设备在临近的频段产生相互干扰,那么可以确定该决策信息通常会包含时间方面的信息,例如:分配第一网络设备和第二网络设备分别在哪一些时间片段可以使用受干扰的频段进行数据传输,更具体地,可以是告知自身在哪些时间段会占用该受干扰的频段,哪些时段则不会占用,那么相对的设备则可以在对方不使用该受干扰的频段的时间段内使用该受干扰的频段,这样就可以避免相互干扰。
本发明实施例,由工作于非授权频段的网络设备在受干扰后,主动上报干扰的情况给工作于授权频段的网络设备,由工作于授权频段的网络设备决策如何使用受干扰的频段,通过时分复用的方式复用该受干扰的频段避免相互干扰,并充分利用该受干扰的频段。因此以上方案,采用主动的方式消除授权频段与非授权频段的网络之间的相互干扰,降低因WLAN设备被动增加阻塞干扰功能增加的成本。
通过实际测试,发现第一网络设备的上行接收受到第二网络设备的下 行发送的干扰的情况较为严重,远远严重于其他情况下的干扰,因此本发明实施例可以重点针对此种应用场景进行处理,具体如下:上述第一网络设备确定受到第二网络设备的干扰,包括:
第一网络设备确定上述第一网络设备的上行接收受到上述第二网络设备的下行发送的干扰。
在本发明实施例中,第一网络设备和第二网络设备之间可能本身有通信接口可以建立通信连接,也可能第一网络设备和第二网络设备之间并没有直接通信的接口,本发明实施例提供了干扰告知信息从第一网络设如何发送给第二网络设备的具体实现方案举例,如下:上述向上述第二网络设备发送干扰告知信息包括:
通过上述第一网络设备与上述第二网络设备之间的通信接口,向上述第二网络设备发送干扰告知信息;或者,
通过上述与上述第一网络设备和上述第二网络设备均有通信连接的终端设备,向上述第二网络设备发送干扰告知信息。
在本实施例中,假定上述第一网络设备是WIFI AP,上述第二网络设备是LTE eNB;WIFI AP通常会连接到有线网络,该有线网络会归属于第一运营商,WIFI AP在进行数据传输过程中实际将会使用第一运营商的网络,包括:网关服务器等设备;LTE eNB会归属于第二运营商;第一运营商和第二运营商是不同的运营商,那么WIFI AP与LTE eNB之间通常不会有通信连接。即使第一运营商和第二运营商是同一运营商,还有可能WIFI AP的信号发射距离过短没有发射到LTE eNB的能力,或者运营商没有部署WIFI AP与LTE eNB之间的通信接口;种种应用场景均可能造成第一网络设备和第二网络设备之间可能本身没有通信接口可以建立通信连接。但是,为了提高通信的效率,在一些应用场景中,WIFI AP和LTE eNB之间可以设立直接的通信接口,另外,随着eNB可能在未来融合WIFI AP的一些功能,那么WIFI AP和LTE eNB之间设立直接的通信接口可以被实现。
在本实施例中,第二种方案由终端设备作为纽带传递了干扰告知信息, 终端设备可以是能过与第一网络设备和第二网络设备均能建立通信连接的终端设备,例如:手机可以建立WIFI连接也可以建立LTE连接,即:可以与WLAN AP建立连接,也可以与LTE eNB建立连接;干扰告知信息可以是WLAN AP发送给终端设备然后终端设备转发,也可以是在WLAN AP与终端设备在未建立通信连接或者已经建立通信连接之后,通过测量相应信道之后以测量结果的形式发送给LTE eNB。具体采用何种形式,可以依不同的应用场景选用,本实施例不作唯一性限定。
本发明实施例还提供了使用时分复用的方式中,决策信息具体是何种信息,以及对应该具体信息的时分复用实现方案,具体如下:上述决策信息携带有第一时段和第二时段的信息,上述第一时段为上述第二网络设备在上述受干扰的频段的工作时段,上述第二时段为上述第二网络设备在上述受干扰的频段的非工作时段;
上述第一网络设备按照上述决策信息与上述第二网络设备以时分复用的方式使用被干扰的频段包括:
上述第一网络设备将上述决策信息发送给使用上述受干扰的频段的终端设备,在上述第二时段与上述终端设备使用上述受干扰的频段,在上述第一时段不使用上述受干扰的频段或者在上述第一时段在上述受干扰的频段接收来自上述终端发送的服务质量需求低于预定阈值的业务数据包。
在本实施例中,第一时间段和第二时间段可以采用具体的时间信息,例如:告知某一时间段作为第一时间段,LTE开启,另一时间段作为第二时间段,LTE关闭;也可以是告知的周期性时间,例如:每一个时间分片,例如:20秒,前10秒LTE开启,后10秒LTE关闭。或者采用其他具体表现形式,只要能告知哪一时间段第二网络设备会用该受干扰的频段另一时间段第二网络设备不会用该受干扰的频段就可以,不会影响本发明实施例的实现,本发明实施例对具体的表现形式不作唯一性限定。
在本实施例中,第一网络设备会向终端设备发送决策信息,具体可以采用无线资源控制(Radio Resource Control,RRC)信令,也可以为媒体 接入控制(Medium Access Control,MAC)控制系统(Control System,CE)信令,还可以通过层1(Layer 1)控制信令,具体采用何种信令可以依据具体的应用场景选择,本发明实施例对携带上述询问内容的具体信令不作唯一性限定。
可选地,作为一个最可能应用场景的举例,具体如下:上述第一频段为无线局域网使用的非授权频段,上述第二工作频段为分时长期演进系统使用的授权频段;
上述第一网络设备为无线局域网的接入点;上述第二网络设备为演进型基站或基站控制器。
本发明实施例还提供了另一种数据传输控制方法,如图3所示,包括:
301:第二网络设备接收来自第一网络设备的干扰告知信息,依据上述干扰告知信息确定受干扰的频段;上述第一网络设备工作于非授权频段,上述第二网络设备工作于授权频段;
在本发明实施例中“第一”和“第二”用于区分两种不同的网络设备,不应理解为具有其他技术含义。非授权频段可以是例如:WIFI、蓝牙、紫峰等无线传输方式对应的不需要授权的无线传输频段;授权频段可以是3G,LTE等无线传输方式对应的需要授权的无线传输频段。第一网络设备通常来说可以是WLAN的接入点,第二网络设备则可以是授权接入频段对应的通信系统,例如:LTE的基站或者基站控制器等网络设备。本发明实施例中所称的工作于某一频段是指使用该频段的无线资源进行数据/信令等的通信。
通过实际测试,发现第一网络设备的上行接收受到第二网络设备的下行发送的干扰的情况较为严重,远远严重于其他情况下的干扰,因此本发明实施例可以重点针对此种应用场景进行处理,具体如下:上述第二网络设备接收来自第一网络设备的干扰告知信息,包括:
第二网络设备接收第一网络设备确定上述第一网络设备的上行接收受到上述第二网络设备的下行发送的干扰后发送的干扰告知信息。
302:上述第二网络设备确定决策信息,并将上述决策信息发送给上述第一网络设备;
本实施例中,决策信息会用于指导第一网络设备进行非授权频段的数据/信令传输,那么决策信息应当包含告知第一网络设备如何避免第一网络设备与第二网络设备在已经受干扰的频段继续干扰的信息。由于后续基于将使用的时分复用的方式避免第一网络设备和第二网络设备在临近的频段产生相互干扰,那么可以确定该决策信息通常会包含时间方面的信息,例如:分配第一网络设备和第二网络设备分别在哪一些时间片段可以使用受干扰的频段进行数据传输,更具体地,可以是告知自身在哪些时间段会占用该受干扰的频段,哪些时段则不会占用,那么相对的设备则可以在对方不使用该受干扰的频段的时间段内使用该受干扰的频段,这样就可以避免相互干扰。那么,如何确定自身工作的时段其他时段不工作在该受干扰的频段,可以依据负载情况、服务质量要求等确定,也可以与第一网络设备协商确定;具体如何决策本实施例不作唯一性限定。
303:上述第二网络设备按照上述决策信息与上述第一网络设备以时分复用的方式使用受干扰的频段。
本发明实施例,由工作于非授权频段的网络设备在受干扰后,主动上报干扰的情况给工作于授权频段的网络设备,由工作于授权频段的网络设备决策如何使用受干扰的频段,通过时分复用的方式复用该受干扰的频段避免相互干扰,并充分利用该受干扰的频段。因此以上方案,采用主动的方式消除授权频段与非授权频段的网络之间的相互干扰,降低因WLAN设备被动增加阻塞干扰功能增加的成本。

通过上述第一网络设备与上述第二网络设备之间的通信接口,接收来自第一网络设备的干扰告知信息;或者,
通过上述与上述第一网络设备和上述第二网络设备均有通信连接的终端设备,接收来自第一网络设备的干扰告知信息。
在本实施例中,第二种方案由终端设备作为纽带传递了干扰告知信息,终端设备可以是能过与第一网络设备和第二网络设备均能建立通信连接的终端设备,例如:手机可以建立WIFI连接也可以建立LTE连接,即:可以与WLAN AP建立连接,也可以与LTE eNB建立连接;干扰告知信息可以是WLAN AP发送给终端设备然后终端设备转发,也可以是在WLAN AP与终端设备在未建立通信连接或者已经建立通信连接之后,通过测量相应信道之后以测量结果的形式发送给LTE eNB。具体采用何种形式,可以依不同的应用场景选用,本实施例不作唯一性限定。
本发明实施例还提供了使用时分复用的方式中,决策信息具体是何种信息,以及对应该具体信息的时分复用实现方案,具体如下:上述确定决策信息包括:

在本实施例中,第一时间段和第二时间段可以采用具体的时间信息,例如:告知某一时间段作为第一时间段,LTE开启,另一时间段作为第二时间段,LTE关闭;也可以是告知的周期性时间,例如:每一个时间分片,例如:20秒,前10秒LTE开启,后10秒LTE关闭。或者采用其他具体表现形式,只要能告知哪一时间段第二网络设备会用该受干扰的 频段另一时间段第二网络设备不会用该受干扰的频段就可以,不会影响本发明实施例的实现,本发明实施例对具体的表现形式不作唯一性限定。
可选地,作为一个最可能应用场景的举例,具体如下:上述第一频段为无线局域网使用的非授权频段,上述第二工作频段为分时长期演进系统使用的授权频段;
上述第一网络设备为无线局域网的接入点;上述第二网络设备为演进型基站或基站控制器;
上述第一上述干扰告知信息中携带上述第一网络设备在某时间段内接收信道的信噪比。
以下实施例将以图1C所示的具体应用场景为例,对本发明实施例进行具体的举例说明,包含两种实现方式,如下:
第一种:
步骤一:如图1C所示,在T1时刻,WLAN AP#1的上行接收受到了TD LTE eNB下行发送的干扰。WLAN AP#1可以通过与TD LTE eNB相连接的接口告知TD LTE eNB自己的干扰情况(发送干扰通知),比如:可以告知自己一段时间内接收信道的信噪比(Signal to Interference plus Noise Ratio,SINR)。
步骤二:TD LTE eNB在收到WLAN AP的干扰通知后,TD LTE eNB可以配置一个TDM pattern,比如:LTE ON的时间为10ms,LTE OFF的时间为10ms。TD LTE eNB可以通过与WLAN AP#1相连接的接口告知WLAN AP#1 TDM pattern的配置。
步骤三:WLAN AP#1收到该TDM pattern后,通过修改的Beacon信令告知与其连接的WLAN STA#1该TDM pattern。
步骤四:在LTE OFF时间段,WLAN STA#1就可以发送数据给WLAN AP#1,而WLAN AP#1的接收就会免受TD LTE eNB的干扰。在LTE ON时间段,WLAN STA#1会向WLAN AP#1发送数据,或只发送QoS要求低的业务数据包。
第二种:
步骤一:如图1C所示,在T1时刻,WLAN AP#2的上行接收受到了TD LTE eNB下行发送的干扰。WLAN AP#2可以通过与TD LTE eNB和WLAN AP#2同时连接的UE#1测量和上报,通知TD LTE eNB自己的干扰情况。比如WLAN AP#2先通过WLAN MAC层信令告知UE#1的WLAN模块自己的干扰情况,然后UE#1通过自己的LTE模块告知TD LTE eNB自己收到WLAN AP#2的干扰情况。
步骤二:在收到WLAN AP#2的干扰信息后,TD LTE eNB可以配置一个TDM pattern,比如:LTE ON的时间为10ms,LTE OFF的时间为10ms。TD LTE eNB可以通过与TD LTE eNB和WLAN AP#2同时连接的UE#1测量和上报,通知WLAN AP#2该TDM pattern。比如TD LTE eNB先通过RRC信令将该TDM pattern告诉UE#1,然后UE#1通过自己的WLAN模块告知WLAN AP#2该TDM pattern。
步骤三:WLAN AP#2收到该TDM pattern后,通过修改的Beacon信令告知与其连接的WLAN STA#2该TDM pattern。
步骤四:在LTE OFF时间段,WLAN STA#2就可以发送数据给WLAN AP#2,而WLAN AP#2的接收就会免受TD LTE eNB的干扰。在LTE ON时间段,WLAN STA#2不会向WLAN AP#2发送数据,或只发送QoS要求低的业务数据包。
采用本发明实施例的技术方案带来具有以下明显的优点和效果:
LTE eNB可以动态配置LTE ON/OFF pattern,避免对WLANAP上行接收的干扰。
LTE eNB可以通过多种方式动态的将LTE ON/OFF pattern通知给WLANAP。
WLAN AP可以将LTE ON/OFF pattern动态的告知所连接的WLAN STA,指导WLAN STA在LTE OFF时期向WLAN AP进行上行传输,避免WLAN AP的接收受到干扰,提高传输效率。

基于本发明实施例中使用的时分复用的方式避免第一网络设备和第 二网络设备在临近的频段产生相互干扰,那么可以确定该决策信息通常会包含时间方面的信息,例如:分配第一网络设备和第二网络设备分别在哪一些时间片段可以使用受干扰的频段进行数据传输,更具体地,可以是告知自身在哪些时间段会占用该受干扰的频段,哪些时段则不会占用,那么相对的设备则可以在对方不使用该受干扰的频段的时间段内使用该受干扰的频段,这样就可以避免相互干扰。

通信控制单元504,用于控制上述第二网络设备按照上述决策信息与上述第一网络设备以时分复用的方式使用受干扰的频段。
在本发明实施例中“第一”和“第二”用于区分两种不同的网络设备,不应理解为具有其他技术含义。非授权频段可以是例如:WIFI、蓝牙、紫峰等无线传输方式对应的不需要授权的无线传输频段;授权频段可以是3G,LTE等无线传输方式对应的需要授权的无线传输频段。第一网络设备通常来说可以是WLAN的接入点,第二网络设备则可以是授权接入频段对应的通信系统,例如:LTE的基站或者基站控制器等网络设备。本发明实施例中所称的工作于某一频段是指使用该频段的无线资源进行数据/信令等的通信。
本实施例中,决策信息会用于指导第一网络设备进行非授权频段的数据/信令传输,那么决策信息应当包含告知第一网络设备如何避免第一网络设备与第二网络设备在已经受干扰的频段继续干扰的信息。由于后续基于将使用的时分复用的方式避免第一网络设备和第二网络设备在临近的 频段产生相互干扰,那么可以确定该决策信息通常会包含时间方面的信息,例如:分配第一网络设备和第二网络设备分别在哪一些时间片段可以使用受干扰的频段进行数据传输,更具体地,可以是告知自身在哪些时间段会占用该受干扰的频段,哪些时段则不会占用,那么相对的设备则可以在对方不使用该受干扰的频段的时间段内使用该受干扰的频段,这样就可以避免相互干扰。那么,如何确定自身工作的时段其他时段不工作在该受干扰的频段,可以依据负载情况、服务质量要求等确定,也可以与第一网络设备协商确定;具体如何决策本实施例不作唯一性限定。
本发明实施例,由工作于非授权频段的网络设备在受干扰后,主动上报干扰的情况给工作于授权频段的网络设备,由工作于授权频段的网络设备决策如何使用受干扰的频段,通过时分复用的方式复用该受干扰的频段避免相互干扰,并充分利用该受干扰的频段。因此以上方案,采用主动的方式消除授权频段与非授权频段的网络之间的相互干扰,降低因WLAN设备被动增加阻塞干扰功能增加的成本。
通过实际测试,发现第一网络设备的上行接收受到第二网络设备的下行发送的干扰的情况较为严重,远远严重于其他情况下的干扰,因此本发明实施例可以重点针对此种应用场景进行处理,具体如下:上述接收单元501,用于接收来自第一网络设备的干扰告知信息,包括:
接收第一网络设备确定上述第一网络设备的上行接收受到上述第二网络设备的下行发送的干扰后发送的干扰告知信息。
在本发明实施例中,第一网络设备和第二网络设备之间可能本身有通信接口可以建立通信连接,也可能第一网络设备和第二网络设备之间并没有直接通信的接口,本发明实施例提供了干扰告知信息从第一网络设如何发送给第二网络设备的具体实现方案举例,如下:上述接收单元501,用于通过上述第一网络设备与上述第二网络设备之间的通信接口,接收来自第一网络设备的干扰告知信息;或者,
通过上述与上述第一网络设备和上述第二网络设备均有通信连接的终端设备,接收来自第一网络设备的干扰告知信息。
在本实施例中,第二种方案由终端设备作为纽带传递了干扰告知信息,终端设备可以是能过与第一网络设备和第二网络设备均能建立通信连接的终端设备,例如:手机可以建立WIFI连接也可以建立LTE连接,即:可以与WLAN AP建立连接,也可以与LTE eNB建立连接;干扰告知信息可以是WLAN AP发送给终端设备然后终端设备转发,也可以是在WLAN AP与终端设备在未建立通信连接或者已经建立通信连接之后,通过测量相应信道之后以测量结果的形式发送给LTE eNB。具体采用何种形式,可以依不同的应用场景选用,本实施例不作唯一性限定。
本发明实施例还提供了使用时分复用的方式中,决策信息具体是何种信息,以及对应该具体信息的时分复用实现方案,具体如下:上述信息确定单元502,用于确定第一时段和第二时段,上述第一时段为上述第二网络设备在上述受干扰的频段的工作时段,上述第二时段为上述第二网络设备在上述受干扰的频段的非工作时段;
上述通信控制单元504,用于控制上述第二网络设备与使用上述受干扰的频段的终端设备在上述第一时段使用上述受干扰的频段,在上述第二时段不使用上述受干扰的频段。
在本实施例中,第一时间段和第二时间段可以采用具体的时间信息,例如:告知某一时间段作为第一时间段,LTE开启,另一时间段作为第二时间段,LTE关闭;也可以是告知的周期性时间,例如:每一个时间分片,例如:20秒,前10秒LTE开启,后10秒LTE关闭。或者采用其他具体表现形式,只要能告知哪一时间段第二网络设备会用该受干扰的频段另一时间段第二网络设备不会用该受干扰的频段就可以,不会影响本发明实施例的实现,本发明实施例对具体的表现形式不作唯一性限定。
可选地,作为一个最可能应用场景的举例,具体如下:上述第一频段为无线局域网使用的非授权频段,上述第二工作频段为分时长期演进系统使用的授权频段;
