背景技术

【术语解释】
LoRa：一种基于扩频技术的低功耗远距离无线传输方案。
LoRaWAN：LoRa Wide Area Network是一种低功耗广域物联网解决方案。
NS：Network Server，网络服务器。
BS：Base Station，基站。
Beacon Frame：信标帧。
GWEUI：基站扩展唯一标识符(Gateway Extended Unique Identifier，GWEUI)，如可以是64位EUI。
基站标识列表：指包含能够区分不同基站的参数信息的列表。参数信息可以是基站标识，即基站扩展唯一标识符(Gateway Extended Unique Identifier，GWEUI)。另外，参数信息也可以是基站位置信息(或者经纬度信息)以及接收信号强度信息中的至少一种。
【终端与基站的通信方法】
为了提高判断的准确度，节省终端的功耗，本公开提出，可以将地理位置信息与接收信号强度信息的组合，或者地理位置信息，作为用于标识基站的参数信息，通过比较当前接收到的信标帧的参数信息与之前接收到的信标帧的参数信息之间的变化幅度，判断本次接收到信标帧与之前接收到的信标帧是否同一基站发出的。例如，可以通过比较 当前接收到的信标帧中的基站的地理位置信息与之前接收到的信标帧中的基站的地理位置信息之间的距离是否超过第一预定阈值，来判断本次接收到信标帧与之前接收到的信标帧是否同一基站发出的。再例如，也可以同时比较当前接收到的地理位置信息与之前接收到的地理位置信息之间的距离是否超过第一预定阈值以及信标帧的接收信号强度之间的差异是否超过第二预定阈值，来判断当前接收到信标帧与之前接收到的信标帧是否同一基站发出的。
另外，本公开提出，也可以通过比较当前接收到的信标帧中的GWEUI是否与之前接收到的信标帧中的GWEUI一致，判断本次接收到信标帧与之前接收到的信标帧是否同一基站发出的。
与仅单纯比较信标帧中的GPS信息是否发生变化相比，本公开的判断方式更为准确，可以减少终端发送无谓的基站更新帧的次数，降低终端耗能，延长终端电池的使用寿命。
下面分别就本公开提出的判断方式的实现过程做进一步说明。
方式一：
图1是示出了根据本公开一实施例的终端与基站的通信方法的示意性流程图。其中，图1所示的方法可以由终端执行。
参见图1，在步骤S110，接收第一基站发送的第一信标帧。
在步骤S120，在第一位置信息与第二位置信息之间的距离大于第一预定阈值，或者第一接收信号强度信息与第二接收信号强度信息的差值大于第二预定阈值的情况下，向网络服务器发送第一信息。
第一信标帧包括第一位置信息，第一位置信息用于表征第一基站的位置。第二位置信息用于表征接收到第一信标帧之前接收到的第二信标帧对应的第二基站的位置。其中，第一基站和第二基站可以是同一基站，也可以是不同基站。作为示例，第一位置信息和第二位置信息可以是对应基站的GPS信息，如可以是GPS经纬度信息。
第一接收信号强度信息用于表征征接收到的第一信标帧的接收信号强度。第二接收信号强度信息用于表征接收到第一信标帧之前接收到的第二信标帧的接收信号强度。在本公开中，第二接收强度信息和第二位置信息均可以视为用于标识在接收到第一信标帧之前接收到的第二信标帧对应的第二基站的参数信息。
作为本公开的一个示例，在执行步骤S110之前，还可以接收第二基站发送的第二信标帧，第二信标帧包括第二位置信息。并且，还可以记录第二信标帧的第二接收信号 强度信息。
在接收到第一信标帧后，可以判断第一位置信息与第二位置信息之间的距离是否大于第一预定阈值，且判断第一接收信号强度信息与第二接收信号强度信息的差值是否大于第二预定阈值。其中，第一预定阈值和第二预定阈值的具体数值可以根据实际情况设定，此处不再赘述。
在第一位置信息与第二位置信息之间的距离大于第一预定阈值，或者第一接收信号强度信息与第二接收信号强度信息的差值大于第二预定阈值的情况下，可以认为第一信标帧和第二信标帧是不同基站发出的，即第一基站不同于第二基站，此时可以向网络服务器发送第一信息。
换言之，在第一位置信息与第二位置信息之间的距离不大于第一预定阈值，且第一接收信号强度信息与第二接收信号强度信息的差值不大于第二预定阈值的情况下，可以认为第一信标帧和第二信标帧是同一基站发出的，即第一基站与第二基站是同一基站。因此，如果第一位置信息与第二位置信息之间的距离不大于第一预定阈值，且第一接收信号强度信息与第二接收信号强度信息的差值不大于第二预定阈值，则不向网络服务器发送第一信息。
第一信息用于使得网络服务器基于第一信息更新终端的下行数据对应的基站。其中，第一信息可以是携带一定数据信息的信息帧，如可以是基站更新请求(也即上行路由更新帧)，另外，第一信息也可以是一个空包，关于第一信息所包含的数据内容，本公开不做限定。所发送的第一信息可以被一个或多个基站接收到，并由这一个或多个基站转发至网络服务器，网络服务器可以根据接收到的第一信息的信号接收强度(RSSI)和/或信噪比(SNR)等质量数据，更新此终端下行数据对应的基站，如可以选取信号接收强度(RSSI)和/或信噪比(SNR)最大的基站，作为此终端下行数据对应的基站。
在本公开的一个实施例中，终端可以维护一个基站标识列表(为了便于区分，可以称为“第一基站标识列表”)，第二位置信息和第二接收信号强度信息记录在第一基站标识列表中，如可以关联地记录在第一基站标识列表中。在第一位置信息与第二位置信息之间的距离大于第一预定阈值，或者第一接收信号强度信息与第二接收信号强度信息的差值大于第二预定阈值的情况下，可以认为第一基站与之前接收到的第二信标帧对应的第二基站不同，此时可以将第一位置信息和第一接收信号强度信息写入(可以是关联地写入)第一基站标识列表，作为用于标识第一基站的基站标识参数。由此，第一基站标识列表中可以记录多组分别用于标识不同基站的基站标识参数。在后续接收到新的信 标帧时，可以分别将新的信标帧中的位置信息及其接收信号强度信息与第一基站标识列表中记录的每组基站标识参数(即位置信息和接收信号强度信息)进行比较，如果第一基站标识列表中不存在位置信息差小于第一预定阈值且接收信号强度差小于第二预定阈值的基站标识参数，则可以认为当前接收到的信标帧对应的基站是新的基站，可以向网络服务器发送第一信息。
图2是示出了图1所示的方法应用在LoRaWAN场景中的示意性流程。
图2所示的网络服务器(Network server)可以是LoRaWAN服务器，基站(Gateway)可以是LoRa基站。终端(End-device)和网络服务器之间可以基于LoRaWAN协议进行通信，即终端可以通过一个或多个基站向服务器发送上行数据，服务器也可以通过一个或多个基站向终端发送下行数据。并且，上行数据通过的基站和下行数据通过的基站的分布可以一致，也可以不一致。
在本公开中，终端(End-device)可以是工作在LoRaWAN协议的classB模式下的终端。在classB中，基站每隔128秒发送一次Beacon，End-device定期打开一个接收窗口，称之为“脉冲时隙(ping slot)”，网络服务器在该接收窗口发送的下行通信称之为“脉冲帧(ping frame)”。
如图2所示，1、第二基站(Gateway2)向工作在classB模式下的终端发送第二信标帧，第二信标帧中包括用于表征Gateway2的位置的第二位置信息。
2、将第二位置信息以及终端接收到第二信标帧的第二接收信号强度信息，作为用于区分第二基站的参数信息，记录在第一基站标识列表中。
3、网络服务器向Gateways发送ping frame。
4、Gateways向End-device发送ping frame。
5、第一基站(Gateway1)向终端发送第一信标帧，第一信标帧中包括用于表征Gateway1的位置的第一位置信息。
6、终端将接收到的第一信标帧的两个参数(第一位置信息和第一信标帧的第一接收信号强度信息)与第一基站标识列表中的两个参数进行比较。判断第一位置信息与列表中已存的位置信息(即第二位置信息)之间的距离是否小于一个预设的第一阈值，以及第一接收信号强度信息与列表中已存的接收信号强度信息(即第二接收信号强度信息)之间的差值是否小于一个预设的第二阈值，如果两者均小于各自的预设阈值，则认为第一信标帧与第二信标帧是由同一基站发出的，不发送第一信息，如果不满足上述条件，则执行步骤7。
7、终端向Gateways发送第一信息。
8、Gateways向网络服务器发送第一信息。
9、网络服务器根据第一信息更新针对此终端下行数据对应的基站。例如，网络服务器可以选择接收信号最强的Gateway作为针对此终端下行数据对应的基站。
与单纯比较信标帧中的GPS信息是否发生变化相比，本公开提出的基于GPS信息的变化幅度的判断方式更为准确，可以减少终端发送无谓的基站更新帧的次数，降低终端耗能，延长终端电池的使用寿命。
方式二：
图3是示出了根据本公开另一实施例的终端与基站的通信方法的示意性流程图。其中，图3所示的方法可以由终端执行。
参见图3，在步骤S310，接收第三基站发送的第三信标帧。
在步骤S320，在第三位置信息与第四位置信息之间的距离大于第一预定阈值的情况下，向网络服务器发送第二信息。
第三信标帧包括第三位置信息，第三位置信息用于表征第三基站的位置。第四位置信息用于表征接收到第三信标帧之前接收到的第四信标帧对应的第四基站的位置。其中，第三基站和第四基站可以是同一基站，也可以是不同基站。作为示例，第三位置信息和第四位置信息可以是对应基站的GPS信息，如可以是GPS经纬度信息。
作为本公开的一个示例，在执行步骤S310之前，还可以接收第四基站发送的第四信标帧，第四信标帧包括第四位置信息。
在接收到第三信标帧后，可以判断第三位置信息与第四位置信息之间的距离是否大于第一预定阈值。其中，第一预定阈值的具体数值可以根据实际情况设定，此处不再赘述。
在第三位置信息与第四位置信息之间的距离大于第一预定阈值的情况下，可以认为第三基站与第四基站不同，可以向网络服务器发送第二信息。换言之，在第三位置信息与第四位置信息之间的距离不大于第一预定阈值的情况下，可以认为第三信标帧和第四信标帧是同一基站发出的，即第三基站与第四基站是同一基站。因此，如果第三位置信息与第四位置信息之间的距离不大于第一预定阈值，则不向网络服务器发送第二信息。
与上文述及的第一信息的作用相同，第二信息用于使得网络服务器基于第一信息更新终端的下行数据对应的基站。其中，第二信息可以是携带一定数据信息的信息帧，如可以是基站更新请求(也即上行路由更新帧)，另外，第二信息也可以是一个空包，关 于第一信息所包含的数据内容，本公开不做限定。所发送的第二信息可以被一个或多个基站接收到，并由这一个或多个基站转发至网络服务器，网络服务器可以根据接收到的第二信息的信号接收强度(RSSI)和/或信噪比(SNR)等质量数据，更新此终端下行数据对应的基站，如可以选取信号接收强度(RSSI)和/或信噪比(SNR)最大的基站，作为此终端下行数据对应的基站。
在本公开的一个实施例中，终端可以维护一个基站标识列表(为了便于区分，可以称为“第二基站标识列表”)，第三位置信息记录在第二基站标识列表中。在第三位置信息与第四位置信息之间的距离大于第一预定阈值的情况下，可以认为第三基站与之前接收到的第四信标帧对应的第四基站不同，此时可以将第三位置信息写入第二基站标识列表，作为用于标识第三基站的基站标识参数。由此，第二基站标识列表中可以记录多个分别用于标识不同基站的基站标识参数。在后续接收到新的信标帧的情况下，可以分别将新的信标帧中的位置信息与第二基站标识列表中记录的每个基站标识参数(即位置信息)进行比较，如果第二基站标识列表中不存在位置信息差小于第一预定阈值的基站标识参数，则可以认为当前接收到的信标帧对应的基站是新的基站，可以向网络服务器发送第二信息，并且可以将新的信标帧中的位置信息写入第二基站标识列表。
方式三：
图4是示出了根据本公开另一实施例的终端与基站的通信方法的示意性流程图。其中，图4所示的方法可以由终端执行。
参见图4，在步骤S410，接收第五基站发送的第五信标帧。
在步骤S420，在第一基站标识与第二基站标识不一致的情况下，向网络服务器发送第三信息。
第五信标帧中包括第一基站标识，第一基站标识用于标识发送第五信标帧的第五基站。第二基站标识用于标识接收到第五信标帧之前接收到的第六信标帧对应的第六基站。其中，第五基站和第六基站可以是同一基站，也可以是不同基站。第一基站标识和第二基站标识可以是基站扩展唯一标识符(Gateway Extended Unique Identifier，GWEUI)，如可以是64位EUI。
作为本公开的一个示例，在执行步骤S410之前，还可以接收第六基站发送的第六信标帧，第六信标帧包括第二基站标识。
在接收到第五信标帧后，可以判断第一基站标识与第二基站标识是否一致。如果第一基站标识与第二基站标识一致，则可以认为第五信标帧和第六信标帧是同一基站发出 的，即第五基站与第六基站是同一基站。因此，在第一基站标识与第二基站标识一致的情况下，不向网络服务器发送第三信息。如果第一基站标识与第二基站标识不一致，则可以认为第五信标帧和第六信标帧不是同一基站发出的，即第五基站与第六基站不是同一基站。因此，在第一基站标识与第二基站标识不一致的情况下，向网络服务器发送第三信息。
与上文述及的第一信息、第二信息的作用相同，第三信息用于使得网络服务器基于第三信息更新终端的下行数据对应的基站。其中，第三信息可以是携带一定数据信息的信息帧，如可以是基站更新请求(也即上行路由更新帧)，另外，第三信息也可以是一个空包，关于第一信息所包含的数据内容，本公开不做限定。所发送的第三信息可以被一个或多个基站接收到，并由这一个或多个基站转发至网络服务器，网络服务器可以根据接收到的第三信息的信号接收强度(RSSI)和/或信噪比(SNR)等质量数据，更新此终端下行数据对应的基站，如可以选取信号接收强度(RSSI)和/或信噪比(SNR)最大的基站，作为此终端下行数据对应的基站。
在本公开的一个实施例中，终端可以维护一个基站标识列表(为了便于区分，可以称为“第三基站标识列表”)，第二基站标识可以记录在第三基站标识列表中。在第一基站标识与第二基站标识不一致的情况下，可以认为第五基站与第六基站不同，此时可以将第一基站标识写入第三基站标识列表，作为用于标识第五基站的基站标识参数。由此，第三基站标识列表中可以记录多个分别用于标识不同基站的基站标识参数。在后续接收到新的信标帧的情况下，可以分别将新的信标帧中的基站标识与第三基站标识列表中记录的每个基站标识参数(即基站标识)进行比较，如果新的信标帧中的基站标识没有出现在第三基站标识列表中，则可以认为当前接收到的信标帧对应的基站是新的基站，可以向网络服务器发送第三信息，并且可以将新的信标帧中的基站标识写入第三基站标识列表。
图5是示出了图4所示的方法应用在LoRaWAN场景中的示意性流程。
图5所示的网络服务器可以是LoRaWAN服务器，基站(Gateway)可以是LoRa基站。终端(End-device)和网络服务器之间可以基于LoRaWAN协议进行通信，即终端可以通过一个或多个基站向服务器发送上行数据，服务器也可以通过一个或多个基站向终端发送下行数据。并且，上行数据通过的基站和下行数据通过的基站的分布可以一致，也可以不一致。
在本公开中，End-device可以是工作在LoRaWAN协议的classB模式下的终端。在 classB中，基站每隔128秒发送一次Beacon，End-device定期打开一个接收窗口，称之为“脉冲时隙(ping slot)”，网络服务器在该接收窗口发送的下行通信称之为“脉冲帧(ping frame)”。
如图5所示，1、第六基站(Gateway6)向工作在classB模式下的终端发送第六信标帧，第六信标帧中包括用于标识第六基站的第二基站标识。
2、终端在收到携带有第二基站标识的第六信标帧后，可以将第二基站标识记录到第三基站标识列表中。
3、网络服务器向Gateways发送ping frame。
4、由Gateways(如Gateway6)向End-Device转发网络服务器发送的ping frame。
如图5中步骤5-9所示，如果后续第五基站(Gateway5)向工作在classB模式下的终端发送第五信标帧，第五信标帧中包括用于标识第五基站的第一基站标识。终端可以将收到的第五信标帧中携带的第一基站标识与上一次收到的第六信标帧中的第二基站标识进行判断，如可以判断第三基站标识列表中是否存在与第一基站标识一致的基站标识，如果存在则表明不需要发送第三信息，如果不存在则需要发送第三信息，并且还可以将第一基站标识写入第三基站标识列表。作为示例，终端发送的第三信息可以通过Gateway1和/或Gateway2发送至网络服务器。网络服务器可以根据第三信息更新此终端下行数据对应的基站，如可以选择接收信号最强的Gateway作为此终端下行数据对应的基站。
如图5中步骤10-11所示，如果后续终端接收到新的信标帧，则可以判断第三基站标识列表中是否存在与新的信标帧中的基站标识一致的基站标识，如果存在则不发送第三信息，否则发送第三信息。例如，假设Gateway6再次向工作在classB模式下的终端发送Beacon帧，Beacon帧里面携带GWEUI6。终端可以将收到的Beacon帧中携带的GWEUI6与第三基站标识列表中的GWEUI进行比较，判断GWEUI6在第三基站标识列表里面，不发送第三信息。
与单纯比较信标帧中的GPS信息是否发生变化相比，本实施例通过比较基站标识(GWEUI)的判断方式更为准确，可以减少终端发送无谓的基站更新帧的次数，降低终端耗能，延长终端电池的使用寿命。
图6是示出了根据本公开另一实施例的终端与基站的通信方法的示意性流程图。其中，图6所示的方法可以由终端执行。
如图6所示，在步骤S610，接收第七基站发送的第七信标帧。
在步骤S620，在第一基站标识参数与第四基站标识列表中的各个已有基站标识参数的差异均大于预定阈值的情况下，向网络服务器发送第四信息。
第一基站标识参数用于标识第七基站。第四基站标识列表中可以包括多个已有基站标识参数，每个已有基站标识参数可以用于表征在接收到第七信标帧之前接收到的一个信标帧对应的基站。例如，如果在接收到第七信标帧之前，还接收到了来自基站1的信标帧1、来自基站2的信标帧2、来自基站3的信标帧3，那么第四基站标识列表中可以包括用于表征基站1的基站标识参数1、用于表征基站2的基站标识参数2以及用于表征基站3的基站标识参数3。
在本公开中，基站标识参数可以是用于表征基站的位置的位置信息，也可以是用于表征基站的位置的位置信息和用于表征基站发送的信标帧的接收信号强度的接收信号强度信息的组合。
在基站标识参数是位置信息的情况下，第七信标帧中包括用于表征第七基站的第七位置信息。可以将第七位置信息与第四基站标识列表中的各个已有基站标识参数(即已有位置信息)进行比较，判断第四基站标识列表中是否存在与第七位置信息的距离小于第一预定阈值的已有位置信息，如果存在，则表明发送第七信标帧的第七基站不是新的基站，不向网络服务器发送第四信息。如果不存在，则表明发送第七信标帧的第七基站是新的基站，向网络服务器发送第四信息。
在基站标识参数是位置信息和接收信号强度信息的组合的情况下，第七信标帧中包括用于表征第七基站的第七位置信息，可以记录接收到第七信标帧的接收信号强度信息(为了便于区分，可以称为“第三接收信号强度信息”)。可以将第七位置信息和第三接收信号强度信息与第四基站标识列表中记录的每组基站标识参数(即位置信息和接收信号强度信息)进行比较，如果第四基站标识列表中不存在位置信息差小于第一预定阈值且接收信号强度差小于第二预定阈值的基站标识参数，则可以认为发送第七信标帧的第七基站是新的基站，向网络服务器发送第四信息。
与上文述及的第一信息的作用相同，第四信息用于使得网络服务器基于第一信息更新终端的下行数据对应的基站。其中，第四信息可以是携带一定数据信息的信息帧，如可以是基站更新请求(也即上行路由更新帧)，另外，第四信息也可以是一个空包，关于第四信息所包含的数据内容，本公开不做限定。所发送的第四信息可以被一个或多个基站接收到，并由这一个或多个基站转发至网络服务器，网络服务器可以根据接收到的 第四信息的信号接收强度(RSSI)和/或信噪比(SNR)等质量数据，更新此终端下行数据对应的基站，如可以选取信号接收强度(RSSI)和/或信噪比(SNR)最大的基站，作为此终端下行数据对应的基站。
图7是示出了根据本公开另一实施例的终端与基站的通信方法的示意性流程图。其中，图7所示的方法可以由终端执行。
参见图7，在步骤S710，接收第八基站发送的第八信标帧，第八信标帧包括第三基站标识。
在步骤S720，在第三基站标识与第五基站标识列表中的各个已有基站标识均不一致的情况下，向网络服务器发送第五信息。
第三基站标识用于标识发送第八信标帧的第八基站。第五基站标识列表中可以包括多个已有基站标识，每个已有基站标识可以用于标识在接收到第七信标帧之前接收到的一个信标帧对应的基站。例如，如果在接收到第七信标帧之前，还接收到了来自基站1的信标帧1、来自基站2的信标帧2、来自基站3的信标帧3，那么第五基站标识列表中可以包括用于标识基站1的已有基站标识1、用于标识基站2的已有基站标识2以及用于标识基站3的已有基站标识3。基站标识可以是基站扩展唯一标识符(Gateway Extended Unique Identifier，GWEUI)，如可以是64位EUI。
在接收到第八信标帧后，可以将第八信标帧中的第三基站标识与基站列表中的各个已有基站标识进行比较，如果第三基站标识与第五基站标识列表中的各个已有基站标识均不一致，即第三基站标识未出现在第五基站标识列表中，则可以认为发送第八信标帧的第八基站是新的基站，向网络服务器发送第五信息。如果第三基站标识出现在第五基站标识列表中，则可以认为发送第八信标帧的第八基站不是新的基站，不向网络服务器发送第五信息。
与上文述及的第一信息的作用相同，第五信息用于使得网络服务器基于第一信息更新终端的下行数据对应的基站。其中，第五信息可以是携带一定数据信息的信息帧，如可以是基站更新请求(也即上行路由更新帧)，另外，第五信息也可以是一个空包，关于第五信息所包含的数据内容，本公开不做限定。所发送的第五信息可以被一个或多个基站接收到，并由这一个或多个基站转发至网络服务器，网络服务器可以根据接收到的第五信息的信号接收强度(RSSI)和/或信噪比(SNR)等质量数据，更新此终端下行数据对应的基站，如可以选取信号接收强度(RSSI)和/或信噪比(SNR)最大的基站，作为此终端下行数据对应的基站。
