Description

基于盲区中实现高频通信的处理方法、装置和设备 技术领域
本发明实施例涉及无线通信技术，特别涉及一种基于盲区中实现高频通信的处理方法、装置和设备。
背景技术
随着通信技术的快速发展，通信网络中对系统容量、数据吞吐率、传输时延及传输可靠性的要求也越来越高，而由于传统的微波频段所能提供的带宽十分有限，满足不了日益增长的需求，因此移动通信势必会向更高频段的毫米波段发展。目前，毫米波(高频)通信的优点是容量大，数据吞吐率高，但大气，水雾及障碍物的对毫米波通信的衰耗很大，一般高频基站的覆盖范围较小。另外，在高频组网通信中，由于毫米波易受环境干扰影响，高频基站的覆盖区域内会以一定概率出现盲区，例如：建筑物的阻挡、人体阻挡或者干扰等因素，因此，导致用户设备(User Equipment；简称：UE)接收信号很弱甚至无法有效解调。
现有技术中主要通过引入多级波束切换机制以解决上述技术问题，从而保证高频通信可靠性。具体的，该通过引入多级波束切换机制的工作原理主要为：在高低频混合组网的情况下，UE可以接收到很多来自相同或不同基站的波束，UE选择信号质量最好的波束接入链路之后，仍然对其它可接收的波束信号进行周期性的测量，并在满足可接入链路的目标波束中进行优先级排序，其中，优先级顺序可以是：(1)与当前接入波束具有相同的控制信道；(2)与当前接入波束的控制信道不同，但是具有相同的小区；(3)与当前接入波束的小区不同，但是具有相同的蜂窝基站；(4)与当前接入波束通过有线相连的不同的蜂窝基站，(5)与当前接入波束通过无线相连的不同的蜂窝基站。当接入波束通信质量恶化甚至通信中断时，首先尝试恢复当前波束的通信质量，若恢复不了，则按照上述的优先级顺序切换至其它的目标波束，以保持通信的连续性。
然而，现有技术中当UE受障碍物阻挡或其它干扰进入盲区，导致链路 突然中断或者恶化到无法正常解调，而且此时没有可以切换的波束，或者本可以用来切换的波束受障碍物阻挡或其它干扰，信号质量也恶化到无法正常接收时，高频通信会被中断，依然会导致系统的可靠性较低的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例仅仅是本发明一部分实施例，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他实施例，都属于本发明保护的范围。
图1为本发明基于盲区中实现高频通信的处理方法的应用场景之一(即高低频宏/微组网架构)的架构示意图。此场景中，以宏站和小站作为基站为例进行说明。如图1所示，在高低频宏/微组网架构中，主要包括：宏站11、 小站12和UE 13。其中，宏站11一般采用传统的蜂窝频段，例如可以是2GHz，也可以采用频点较低的毫米波频段以达到覆盖较大区域控制面的目的，其中，频点较低的毫米波频段例如可以是3.5GHz等，宏站11可以通过上述的蜂窝频段或者毫米波频段与小站12或UE 13进行相应的信令交互。另外，在宏站11的覆盖范围内，可以布置多个小站12进行热点覆盖，小站12采用频点较高的毫米波频段，例如可以是28GHz、38GHz、E-Band等，以进行较小区域数据面的覆盖。小站12可以通过传统蜂窝频段或者频点较低的毫米波频段与宏站11进行信令交互，但是不能通过上述蜂窝频段或者频点较低的毫米波频段与UE 13进行信令交互。此外，在小站12覆盖范围内的UE 13一般通过频点较高的毫米波频段与小站12进行数据面的交互，通过蜂窝频段或者频点较低的毫米波频段与宏站11进行控制面的交互。当UE进入小站覆盖区域内的盲区后，UE的通信会发生中断，此时，UE需要快速的重新建立高频链接，以保持高频通信的连续性。
另外，在高低频宏/微组网架构中，若只有小站而没有配置宏站时，小站可以代替宏站与UE进行信令的交互。
图2为本发明基于盲区中实现高频通信的处理方法的应用场景之二(即高低频分布式组网架构)的架构示意图。如图2所示，在高低频分布式组网架构中，主要包括：基站14和UE 13。其中，基站14可以采用传统的蜂窝频段，例如：2GHz，或者采用频点较低的毫米波频段与UE 13进行传统的低速蜂窝通信，例如语音传输等，其中频点较低的毫米波频段例如可以是3.5GHz等。另外，基站14还可以采用频点较高的毫米波频段与UE 13进行高速率的通信，例如视频传输等，其中，频点较高的毫米波频段例如可以是28GHz、38GHz、E-Band等。当UE 13进入基站14覆盖区域内的盲区时，UE的通信会发生中断，此时，UE需要快速的重新建立高频链接，以保持高频通信的连续性。
由此可见，无论是在高低频宏/微组网架构中，UE与小站之间进行高频通信，还是在高低频分布式组网架构中，UE与基站之间进行高频通信，当UE进入盲区后，如何快速的重新建立高频链接，以保持通信的连续性，从而提高系统的可靠性是一个非常重要的问题。
需要进行说明的是，图1和图2所示的应用场景均为第三代合作伙伴计 划(3rd Generation Partnership Project；简称：3GPP)的长期演进(Long Term Evolution；简称：LTE)蜂窝网络框架，但是本发明也可以适用于其它具有广域覆盖的蜂窝网络与毫米波蜂窝通信共存的场景中。
图3为本发明基于盲区中实现高频通信的处理方法实施例一的流程示意图。本发明实施例提供了一种基于盲区中实现高频通信的处理方法，该方法可以由任意执行基于盲区中实现高频通信的处理方法的装置来执行，该装置可以通过软件和/或硬件实现。本实施例中，该装置可以集成在宏站/小站/基站中。
在上述图1或图2所示系统架构的基础上，如图3所示，本实施例的方法可以包括：
步骤301、检测UE与当前服务该UE的基站之间的高频链路是否中断。
本实施例中，在高低频宏/微组网架构中，若配置有宏站时，在高频链路突然中断或者恶化到无法进行正常解调的状态时，UE即进入了盲区时，此时，UE会通过低频向与其进行低频连接的宏站发送反馈消息，将盲区的状态标识发送给该宏站，以告知宏站该UE已经处于盲区，且无法进行正常的高频通信，与UE进行低频连接的宏站根据接收到的反馈消息，检测UE与当前服务该UE的基站之间的高频链路是否中断。
而在高低频宏/微组网架构中，且没有配置宏站时，或在高低频分布式组网架构，当高频链路突然中断或者恶化到无法进行正常解调的状态时，小站/基站即可获知UE进入了盲区，便会检测UE与当前服务该UE的基站之间的高频链路是否中断。
步骤302、若确定UE与当前服务该UE的基站之间的高频链路中断，则向能覆盖UE位置的波束所属的待接入基站发送扫描请求消息，以供待接入基站根据扫描请求消息以及当前负载，判断是否扫描UE。
在本实施例中，若UE与当前服务该UE的基站之间高频链路已经中断，且UE经过查询获知所有覆盖UE位置的波束均不能使该UE接入高频链路，也即不存在该UE的备选波束，或者存在备选波束但是切换失败时，则向所有能覆盖UE位置的波束所属的待接入小站/待接入基站发送扫描请求信息。当待接入小站/待接入基站接收到该扫描请求信息之后，根据自身当前的负载，决定是否对该UE进行快速扫描。若待接入小站/待接入基站当前的负载 较小，则确定扫描该UE，若待接入小站/待接入基站当前的负载较大，则不对该UE进行扫描。
其中，获取所有能覆盖UE位置的波束的方法，可以是UE测量之后直接上报给基站，也可以由基站对UE进行定位来获取，对于具体的获取方式，本发明对此不作特别限制。
需要进行说明的是，在高低频分布式组网架构中，基站还可以根据存储的UE的位置信息或者根据打向UE的波束的方向，通过信噪比(Signal to Noise Ratio；简称：SNR)的大小判断出UE的大概位置，当判断出UE的位置之后，便可获知哪些基站的波束可以覆盖UE，则向所有能够覆盖UE位置的波束所属的待接入基站发送扫描请求信息。
步骤303、在接收到待接入基站发送的确定扫描UE的扫描确认消息后，向反馈扫描确认信息的待接入基站发送UE的信息，以供反馈扫描确认信息的待接入基站根据UE的信息，对UE进行快速扫描，以使UE与待接入基站之间重新建立高频连接。
在本实施例中，若待接入小站/待接入基站当前的负载较小，则将确定扫描该UE的信息携带在扫描确认消息中，并通过高层信令发送给宏站/小站/基站，其中，高层信令例如可以是无线资源控制(Radio Resource Control；简称：RRC)信令等。宏站/小站/基站根据扫描确认消息，将UE的信息发送给决定扫描UE的待接入小站/待接入基站。
反馈扫描确认信息的待接入小站/基站根据UE的信息对UE进行快速扫描，并根据当前的负载为UE分配一定的时频资源，同时将波束打向该UE的位置，并通过调整打向该UE的位置的波束的方向，以使UE与待接入基站之间重新建立高频连接。UE通过对波束的相关参数例如可以是信号干扰噪声比(signal to noise and interference ratio；简称：SINR)、信号干扰比(Signal to Interference Ratio；简称：SIR)、信道容量、信号强度等进行测量，根据测量结果从所有能使其接入高频链路的波束中选择一个信号质量最好的波束，通过该波束与待接入基站之间重新建立高频连接，由此可以降低高频系统中断的概率。
本发明实施例提供的基于盲区中实现高频通信的处理方法，通过检测UE与当前服务该UE的基站之间的高频链路是否中断，若确定UE与当前服务该 UE的基站之间的高频链路中断，则向能覆盖UE位置的波束所属的待接入基站发送扫描请求消息，以供待接入基站根据扫描请求消息以及当前负载，判断是否扫描UE，在接收到待接入基站发送的确定扫描UE的扫描确认消息后，向反馈扫描确认信息的待接入基站发送UE的信息，以供反馈扫描确认信息的待接入基站根据UE的信息，对UE进行快速扫描，以使UE与待接入基站之间重新建立高频连接。由于在UE进入盲区且与当前服务该UE的基站之间高频链路中断时，通知能覆盖该UE位置的所有基站，并指示这些基站根据自身的负载决定是否对该UE进行扫描，以使UE能够快速地重新建立高频连接，从而保证了通信的连续性，提高了系统的可靠性。
可选地，待接入基站包括当前服务该UE的基站及其它能与UE建立高频连接的基站。
具体地，在高低频宏/微组网架构中，且配置有宏站时，待接入基站包括当前服务该UE的基站及其它能与UE建立高频连接的基站，因此，与UE进行低频连接的宏站会将扫描请求消息发送给当前服务该UE的基站，以及能与UE建立高频连接的所有基站。
可选地，待接入基站是当前服务该UE的基站以外的其它能与UE建立高频连接的至少一个基站。
具体地，在高低频宏/微组网架构中，且没有配置宏站时，或在高低频分布式组网架构中，待接入基站并不包括当前服务该UE的基站，因此，UE的原高频连接小站/基站会将扫描请求消息发送给能与UE建立高频连接的至少一个基站。
可选地，UE的信息包括UE的标识、UE的扫描周期、UE的定位信息和波束标识。
具体地，UE的标识用于使待接入小站/基站识别对哪一个UE进行扫描，UE的扫描周期用于在扫描时匹配UE的扫描周期，UE的定位信息用于确定UE的位置，使待接入小站/基站在扫描UE时，根据UE的位置将波束打向该UE，波束标识用于通知待接入小站/基站用哪一个波束扫描UE。
本发明实施例提供的基于盲区中实现高频通信的处理方法，通过检测UE与当前服务该UE的基站之间的高频链路是否中断，若确定UE与当前服务该UE的基站之间的高频链路中断，则向能覆盖UE位置的波束所属的待接入基 站发送扫描请求消息，以供待接入基站根据扫描请求消息以及当前负载，判断是否扫描UE，在接收到待接入基站发送的确定扫描UE的扫描确认消息后，向反馈扫描确认信息的待接入基站发送UE的信息，以供反馈扫描确认信息的待接入基站根据UE的信息，对UE进行快速扫描，以使UE与待接入基站之间重新建立高频连接。由于在UE进入盲区且与当前服务该UE的基站之间高频链路中断时，则通知能覆盖该UE位置的所有基站，并指示这些基站根据自身的负载决定是否对该UE进行扫描，以使UE能够快速地重新建立高频连接，从而保证了通信的连续性，提高了系统的可靠性。
在本发明的实施二中，如上所述的方法实施例，可选地，当UE与待接入基站之间重新建立高频连接之后，该方法还可以进一步包括：
在接收到携带有高频连接状态的连接响应消息后，向反馈扫描确认信息的待接入基站中，除与UE重新建立高频连接的基站之外的其它基站发送停止扫描请求消息。
具体地，在高低频宏/微组网架构中，若配置有宏站时，在UE与待接入基站重新建立高频连接之后，UE将高频连接的状态反馈给与UE进行低频连接的宏站，当宏站接收到携带有高频连接状态的连接响应消息后，向所有确定对UE进行快速扫描的待接入小站中，除与UE重新建立高频连接的第二小站之外的其它小站发送停止扫描请求消息，以使其它小站停止对该UE的扫描，节省了小站的资源。
若高低频宏/微组网架构中没有配置宏站，或者在高低频分布式组网架构中，在待接入小站/待接入基站与UE重新建立高频连接之后，此时，由与UE重新建立高频连接的待接入小站/待接入基站将高频连接的状态反馈给UE的原连接小站/基站，当原连接小站/基站接收到携带有高频连接状态的连接响应消息后，停止自身对UE的快速扫描，同时向所有确定对UE进行快速扫描的待接入小站/待接入基站中，除与UE重新建立高频连接的小站/基站之外的其它小站/基站发送停止扫描请求消息，以停止对该UE的扫描，节省了小站/基站的资源。
在本发明的实施三中，如上所述的方法实施例，可选地，该方法还可以进一步包括：
每隔预设周期，检测所有能覆盖UE位置的波束，并将波束的信息发送 给UE，以供UE根据波束的信息对波束进行测量，获得测量结果；其中，波束的信息包括波束标识、小区标识和阵列标识；接收UE发送的测量结果，根据测量结果确定备选波束；备选波束为能使UE与待接入基站之间建立高频连接的波束。
具体地，当UE通过低频接入宏站之后，宏站可以通过GPS等方式定位到可以覆盖该UE的所有波束，同时将这些波束的相关信息通过低频方式发送给UE，其中，波束的相关信息包括波束标识、小区标识和阵列标识等。UE接收到波束的相关信息之后，根据相关信息对波束的相关参数进行测量，其中，波束的相关参数例如可以是SINR、SIR、信道容量、信号强度等。当UE根据测量结果判断得知波束的相关参数的值均大于预设阈值时，说明该波束可以使UE与待接入基站之间建立高频连接。UE根据测量结果选择一个信号质量最好的波束接入高频链路中，并将其它能够使其与待接入基站之间建立高频连接的波束作为备选波束，同时将这些备选波束的信息通过低频反馈给UE的原连接小站/基站。
另外，在高低频宏/微组网架构中，且没有配置宏站时，UE可以对波束进行周期性的测量，以便对备选波束进行周期性的更新。其中，周期值可以由与UE进行低频连接的宏站进行单独配置，然后通过低频通知各个接入的UE，也可以由与UE进行低频连接的宏站进行统一配置，然后通过广播信令通知所有的UE。对于周期的具体值的选取和周期的配置方式，本实施例在此不作特别限制。
在本发明的实施四中，如上所述的方法实施例，可选地，该方法还可以进一步包括：
每隔预设周期，获取所述UE的当前位置，并将所述当前位置作为所述UE的位置。
具体地，在高低频宏/微组网架构中，且该架构中配置有宏站时，由于UE与宏站之间的低频连接并没有中断，因此，UE的原连接宏站可以周期性地测量UE的当前位置，并将测量后获得的UE的当前位置作为该UE的位置。由此可见，随着UE当前位置的改变，覆盖UE位置的波束也会发生变化，也即待接入小站也会发生周期性的更新，这样，可以增大小站与UE重新建立高频链路时成功的概率。
需要进行说明的是，在高低频宏/微组网架构中且没有配置宏站时，或在高低频宏/微组网架构中，由于UE的原连接小站/基站与UE之间的连接已经中断，因此，UE的原连接小站/基站无法周期性地更新UE的当前位置。
本发明实施例提供的基于盲区中实现高频通信的处理方法，通过检测UE与当前服务该UE的基站之间的高频链路是否中断，若确定UE与当前服务该UE的基站之间的高频链路中断，则向能覆盖UE位置的波束所属的待接入基站发送扫描请求消息，以供待接入基站根据扫描请求消息以及当前负载，判断是否扫描UE，在接收到待接入基站发送的确定扫描UE的扫描确认消息后，向反馈扫描确认信息的待接入基站发送UE的信息，以供反馈扫描确认信息的待接入基站根据UE的信息，对UE进行快速扫描，以使UE与待接入基站之间重新建立高频连接。由于在UE进入盲区且与当前服务该UE的基站之间高频链路中断时，通知能覆盖该UE位置的所有基站，并指示这些基站根据自身的负载决定是否对该UE进行扫描，以使UE能够快速地重新建立高频连接，从而保证了通信的连续性，提高了系统的可靠性。另外，通过对备选波束进行周期性的更新，增大了基站与UE重新建立高频链路时成功的机率，降低了高频系统的中断概率。

步骤401、接收UE的原连接基站发送的扫描请求消息，并根据扫描请求消息以及当前负载，判断是否扫描UE。
在本实施例中，当UE进入盲区后，UE的原连接小站/基站会检测UE与当前服务该UE的基站之间的高频链路是否中断，若确定该UE与当前服务该UE的基站之间的高频链路已经中断，且UE经过查询获知所有覆盖UE位置的波束均不能使该UE与小站/基站建立高频连接，也即不存在该UE的备选波束，或者存在备选波束但是切换失败时，该UE的原连接小站/基站向所有 覆盖该UE位置的波束所属的待接入小站/待接入基站发送扫描请求消息。待接入小站/待接入基站接收到UE的原连接小站/基站发送的扫描请求消息之后，判断自身当前的负载，并决定是否对该UE进行扫描，若当前的负载较小，则决定扫描该UE，若当前的负载较大，则不对该UE进行扫描。
步骤402、若确定扫描UE，则向UE的原连接基站发送扫描确认消息，并接收UE的原连接基站发送的UE的信息。
在本实施例中，若待接入小站/待接入基站确定对处于盲区的UE进行扫描，则将确定扫描的消息携带在扫描确认信息中发送给宏站/小站/基站。宏站/小站/基站接收到扫描确认信息后，将UE的信息发送给反馈扫描确认信息的待接入基站。
步骤403、根据UE的信息，对UE进行快速扫描，以使UE重新建立高频连接。
在本实施例中，反馈扫描确认信息的待接入小站/基站在接收到扫描信息后，根据UE的信息对UE进行快速扫描，并根据当前的负载为UE分配一定的时频资源，同时通过调整打向UE的波束的方向，以使UE能够与待接入小站/基站重新建立高频连接。UE通过对波束的相关参数例如可以是SINR、SIR、信道容量、信号强度等进行测量，根据测量结果从所有能使其与待接入小站/基站重新建立高频连接的波束中选择一个质量最好的波束，通过该波束与待接入小站/待接入基站重新建立高频连接。

根据UE的信息，确定UE的位置；根据时频资源和UE的位置，将波束打向UE的位置，以供UE将上行波束与下行波束进行配对并锁定，以使UE重新建立高频连接。
具体地，待接入小站/待接入基站在接收到UE的原连接基站发送的扫描信息之后，根据自身当前的负载为UE分配一定的时频资源，另外，可选地，待接入小站/待接入基站可以根据当前的负载动态的调整对UE分配的时频资源，有助于提高整网的资源利用效率，提升了系统网络的容量。当待接入小站/待接入基站为UE分配一定的时频资源之后，根据UE的信息，确定出UE的位置，根据为UE分配的时频资源和确定出的UE的位置，将波束打向该UE所在的位置，UE将自身发出的上行波束和基站发出的下行波束进行配对，若配对成功，则将波束进行锁定，并通过锁定的波束使UE与待接入小站/待接入基站之间重新建立高频连接。
在本发明的实施例七中，如上所述的方法实施例，可选地，该方法还可以进一步的包括：
向UE的原连接基站发送携带有高频链路连接状态的连接响应消息，以供UE的原连接基站根据连接响应消息，停止对UE的快速扫描，并向发送扫描确认消息的待接入基站中，除与UE重新建立高频连接的基站之外的其它基站发送停止扫描请求消息。
具体地，在高低频宏/微组网架构中，若没有配置宏站时，或者在高低频分布式组网架构中，由与UE重新建立高频连接的小站/基站向UE的原连接小站/基站发送携带有高频链路连接状态的连接响应消息，以供UE的原连接小站/基站根据连接响应消息，停止自身对UE的快速扫描，同时向所有确定对UE进行快速扫描的待接入小站/基站中，除与UE重新建立高频连接的小站/基站之外的其它小站/基站发送停止扫描请求消息，以使其它小站停止对该UE的扫描，节省了小站的资源。
可选地，UE的信息包括UE的标识、UE的扫描周期、UE的定位信息和波束标识。
具体地，UE的标识用于使待接入小站/基站识别对哪一个UE进行扫描，UE的扫描周期用于在扫描时匹配UE的扫描周期，UE的位置信息用于使待接入小站/基站在扫描UE时将波束打向该UE，波束标识用于通知接入小站/ 基站用哪一个波束扫描UE。
