- the relay device 120 sends a carrier wave to the IoT device 130, sends data and/or signals to the IoT device 130, and receives data and/or signals reflected by the IoT device 130.
- the IoT device 130 in the application can be understood as the above-mentioned electronic tag (Tag).
- IoT device 130 may move with or separately from relay device 120. Determining whether the relay device and IoT device move together is an unresolved technical issue. To address this issue, embodiments of the present application propose a method for determining a positional relationship between a relay device and an IoT device.
- FIG5 shows a flow chart of a method for determining a position relationship provided by an exemplary embodiment of the present application.
- the method is executed by a relay device.
- the method includes:
- Step 220 Determine the positional relationship between the relay device and the IoT device.
- the positional relationship between the relay device and the IoT device includes the following two types:
- the positional relationship between the relay device and the IoT device includes a first positional relationship.
- the first positional relationship is used to indicate that a geographical binding relationship exists between the relay device and the IoT device.
- the geographical binding relationship may also be referred to as a mobile binding relationship or a relative position-invariant relationship.
- a geographical binding relationship is used as an example for illustration.
- a geographically bound relationship exists between the relay device and the IoT device, meaning that when the relay device moves, the IoT device follows the movement of the relay device. That is, when the relay device and/or the IoT device moves, the relative positions of the relay device and the IoT device remain substantially unchanged. For example, as shown in FIG6 , assuming that the relay device 120 is at a first position at a first moment, and the IoT device 130, which is geographically bound to the relay device 120, is at a first following position at the first moment, then when the relay device 120 moves from the first position to the second position at a second moment, the IoT device 130 also moves from the first following position to the second following position at the second moment.
- first relative position between the relay device 120 and the IoT device 130 at the first moment is substantially the same as the second relative position between the relay device 120 and the IoT device 130 at the second moment (the relative position between the second position and the second following position).
- the relay device there is a geographical binding relationship between the relay device and the IoT device, which can also be understood as the IoT device is always within the signal coverage range of the relay device.
- a geographical binding relationship exists between the relay device and the IoT device. This can also be understood as a constant connection between the relay device and the IoT device, and this connection does not change with the location of the relay device and/or the IoT device. In other words, even if the relay device and/or the IoT device moves, the connection between the relay device and the IoT device remains.
- a geographically bound relationship exists between the relay device and the IoT device, which can also be understood as ensuring that communication, data transmission, or query-response processes can always be performed between the relay device and the IoT device.
- the query-response process involves the relay device sending a query message to the IoT device, and the IoT device responding to the query message with a response message to the relay device based on the received query message.
- the position relationship between the relay device and the IoT device includes a second position relationship.
- the second position relationship is used to indicate that there is no geographical binding relationship between the relay device and the IoT device.
- the relay device there is no geographic binding relationship between the relay device and the IoT device. This means that when the relay device moves, the IoT device does not follow the movement of the relay device. In other words, the movement of the relay device and the movement of the IoT device are separate and uncorrelated.
- the relay device may be within the relay device's signal coverage at a first moment and outside the relay device's signal coverage at a second moment.
- the relay device may be at a first location at a first moment and at a second location at a second moment.
- the relay device's signal coverage is typically a fixed-size range centered on the relay device. For example, as shown in FIG6 , assuming the signal coverage of relay device 120 is a circular range centered on relay device 120, after relay device 120 moves from a first location to a second location, the signal coverage of relay device 120 remains a circular range centered on relay device 120.
- the position of the center of the circle changes, meaning the position of relay device 120 changes, but the size and shape of the circular range remain unchanged.
- the IoT device may be within the relay device's historical signal coverage at a historical moment but outside the relay device's current signal coverage at the current moment.
- This can also be understood as a connection relationship between the relay device and the IoT device at a first moment but no connection relationship at a second moment.
- this can be understood as a historical connection relationship between the relay device and the IoT device.
- the relay device can communicate or transmit data or execute query-response process with the IoT device at the first moment, but cannot communicate or transmit data at the second moment.
- the relay device can communicate or transmit data or execute query-response process with the IoT device at the first moment, but cannot communicate or transmit data at the second moment.
- a method for determining a positional relationship between a relay device and an IoT device includes at least one of the following:
- Method 1 Determine the positional relationship between the relay device and the IoT device based on the measurement report reported by the IoT device.
- Method 2 Determine the positional relationship between the relay device and the IoT device based on whether a response message fed back by the IoT device is received.
- the method provided in this embodiment by determining the positional relationship between the relay device and the IoT device, makes it possible to determine whether there is a geographical binding relationship between the relay device and the IoT device, so that when there is no geographical binding relationship between the relay device and the IoT device, the network device can promptly provide the IoT device with a replacement relay device.

- the method is performed by a relay device.
- the above step 220 can be replaced by the following sub-steps:
- Step 221 Determine the positional relationship between the relay device and the IoT device based on the measurement report reported by the IoT device.
- the measurement report is used to indicate the quality of the wireless signal measured by the IoT device.
- the wireless signal quality threshold corresponds to the identifier of the relay device.
- wireless signal quality threshold 1 corresponds to relay device 1
- wireless signal quality threshold 2 corresponds to relay device 2.
- the wireless signal quality threshold is determined based on historical measurement results.

- the first measurement report and the second measurement report are reported by the IoT device at different times.
- the first measurement report is reported by the IoT device to the relay device at a first time

- the first measurement report indicates a first wireless signal quality measured by the IoT device at a first moment
- the second measurement report indicates a second wireless signal quality measured by the IoT device at a second moment. It should be understood that the first wireless signal quality and the second wireless signal quality correspond to the same evaluation metric.
- the evaluation metric is the RSRP of a reference signal.
- the first measurement report indicates a first RSRP measured by the IoT device at a first moment

- the first RSRP and the second RSRP may be the same or different.
- the evaluation metric is the RSRQ of the reference signal.
- the first measurement report is used to indicate a first RSRQ measured by the IoT device at a first moment

- the first measurement report indicates a first SINR measured by the IoT device at a first moment
- the second measurement report indicates a second SINR measured by the IoT device at a second moment.
- the first SINR and the second SINR may be the same or different.
- the positional relationship between the relay device and the IoT device is determined to be a first positional relationship. If the absolute difference between the first wireless signal quality and the second wireless signal quality is greater than or equal to the first wireless signal quality threshold, the positional relationship between the relay device and the IoT device is determined to be a second positional relationship.
- the first wireless signal quality threshold is used to indicate the maximum allowable difference in wireless signal quality measured by the IoT device at different times. If the absolute difference in wireless signal quality measured by the IoT device at different times is less than the maximum difference, the positional relationship between the IoT device and the relay device is a first positional relationship. If the absolute difference in wireless signal quality measured by the IoT device at different times is equal to or greater than the maximum difference, the positional relationship between the IoT device and the relay device is a second positional relationship.
- the first wireless signal quality is -30dbm
- the second wireless signal quality is -35dbm
- the first wireless signal quality threshold is 10dbm
- the absolute difference between the first wireless signal quality and the second wireless signal quality is 5dbm. Since 5dbm is less than 10dbm, it can be determined that the position relationship between the relay device and the Internet of Things device is the first position relationship.
- the absolute difference between the first wireless signal quality and the second wireless signal quality is 50dbm. Since 50dbm is greater than 10dbm, it can be determined that the position relationship between the relay device and the Internet of Things device is the second position relationship.
- the measurement time of the IoT device and/or the first wireless signal quality threshold are preconfigured by the network device. In some embodiments, at least one of the first time, the second time, and the first wireless signal quality threshold is preconfigured by the network device.
- the above method further includes: receiving a first measurement report and a second measurement report reported by the IoT device.

- step 221 may be replaced by the following sub-steps:
- Step 2212 Based on the third measurement report reported by the IoT device, determine the position relationship between the relay device and the IoT device.
- the third measurement report is used to indicate that the third wireless signal quality measured by the IoT device is less than the second wireless signal quality threshold. In some embodiments, the third measurement report is sent when the third wireless signal quality measured by the IoT device is less than the second wireless signal quality threshold. In some embodiments, the IoT device measures the third wireless signal quality and only reports the third measurement report when the third wireless signal quality is less than the second wireless signal quality threshold. If the third wireless signal quality is greater than or equal to the second wireless signal quality threshold, the IoT device does not report the third measurement report.
- the second wireless signal quality threshold is used to indicate a minimum value allowed for wireless signal quality measured by the IoT device.

- the IoT device reports a measurement report to the relay device.
- the IoT device does not report the measurement report to the relay device.
- the positional relationship between the relay device and the IoT device is determined to be the second positional relationship. It should be understood that if the IoT device does not report the third measurement report to the relay device, that is, if the relay device does not receive the third measurement report, the positional relationship between the IoT device and the relay device is determined to be the first positional relationship by default.
- the above method further includes: receiving a third measurement report reported by the IoT device.

- the determining module 1710 is further configured to determine connection information corresponding to the second IoT device upon receiving the second response information fed back by the second network device.
- the connection information is used to indicate that a connection relationship has been established between the second IoT device and the apparatus, or to indicate that the second IoT device and the apparatus have communicated.
- the sending module 1730 is further configured to send connection information corresponding to the second IoT device to the network device.
- the sending module 1730 is further configured to send the location relationship to the network device.
- the location relationship is carried in uplink RRC signaling or NAS signaling related to the target event.
- the target event includes a measurement event corresponding to the device.
- the location relationship is carried in the relevant uplink RRC signaling or Non-Access-Stratum (NAS) signaling.
- NAS Non-Access-Stratum
- the manner of sending the location relationship to the network device includes the following two methods:
- Method 1 reporting the first position relationship and reporting the second position relationship
- the network device when it is determined that the positional relationship between the device and the IoT device is a first positional relationship, the network device is informed of the positional relationship. Sending the first position relationship; and when it is determined that the position relationship between the device and the Internet of Things device is the second position relationship, sending the second position relationship to the network device.
- Method 2 Only report the second position relationship.
- the second positional relationship is sent to the network device.
- FIG18 shows a block diagram of a device for determining a position relationship according to an exemplary embodiment of the present application.
- the device includes:
- the receiving module 1810 is configured to receive a position relationship.
- the location relationship is sent by a relay device. In some embodiments, the location relationship is a location relationship between the relay device and the IoT device. In some embodiments, the location relationship includes a first location relationship or a second location relationship, wherein the first location relationship indicates that a geographical binding relationship exists between the relay device and the IoT device, and the second location relationship indicates that no geographical binding relationship exists between the relay device and the IoT device.
- a geographically bound relationship exists between the relay device and the IoT device, meaning that when the relay device moves, the IoT device follows the movement of the relay device. That is, when the relay device and/or the IoT device moves, the relative positions of the relay device and the IoT device remain substantially unchanged. For example, as shown in FIG6 , assuming that the relay device 120 is at a first position at a first moment, and the IoT device 130, which is geographically bound to the relay device 120, is at a first following position at the first moment, then when the relay device 120 moves from the first position to the second position at a second moment, the IoT device 130 also moves from the first following position to the second following position at the second moment.
- first relative position between the relay device 120 and the IoT device 130 at the first moment is substantially the same as the second relative position between the relay device 120 and the IoT device 130 at the second moment (the relative position between the second position and the second following position).
- the relay device there is a geographical binding relationship between the relay device and the IoT device, which can also be understood as the IoT device is always within the signal coverage range of the relay device.
- a geographical binding relationship exists between the relay device and the IoT device. This can also be understood as a constant connection between the relay device and the IoT device, and this connection does not change with the location of the relay device and/or the IoT device. In other words, even if the relay device and/or the IoT device moves, the connection between the relay device and the IoT device remains.
- a geographically bound relationship exists between the relay device and the IoT device, which can also be understood as ensuring that communication, data transmission, or query-response processes can always be performed between the relay device and the IoT device.
- the query-response process involves the relay device sending a query message to the IoT device, and the IoT device responding to the query message with a response message to the relay device based on the received query message.
- the position relationship between the relay device and the IoT device includes a second position relationship.
- the second position relationship is used to indicate that there is no geographical binding relationship between the relay device and the IoT device.
- the relay device there is no geographic binding relationship between the relay device and the IoT device. This means that when the relay device moves, the IoT device does not follow the movement of the relay device. In other words, the movement of the relay device and the movement of the IoT device are separate and uncorrelated.
- the relay device may be within the relay device's signal coverage at a first moment and outside the relay device's signal coverage at a second moment.
- the relay device may be at a first location at a first moment and at a second location at a second moment.
- the relay device's signal coverage is typically a fixed-size range centered on the relay device. For example, as shown in FIG6 , assuming the signal coverage of relay device 120 is a circular range centered on relay device 120, after relay device 120 moves from a first location to a second location, the signal coverage of relay device 120 remains a circular range centered on relay device 120.
- the position of the center of the circle changes, meaning the position of relay device 120 changes, but the size and shape of the circular range remain unchanged.
- the IoT device may be within the relay device's historical signal coverage at a historical moment but outside the relay device's current signal coverage at the current moment.
- This can also be understood as a connection relationship between the relay device and the IoT device at a first moment but no connection relationship at a second moment.
- this can be understood as a historical connection relationship between the relay device and the IoT device.
- the relay device there is no geographic binding relationship between the relay device and the IoT device.
- This can also be understood as the relay device being able to communicate, transmit data, or execute a query-response process with the IoT device at a first moment, but unable to do so at a second moment.
- this can be understood as the existence of a history of communication, data transmission, or query-response processes between the relay device and the IoT device.
- the relay device reports both the first position relationship and the second position relationship.
- the positional relationship between the devices is a first positional relationship
- the first positional relationship is received; and when the positional relationship between the relay device and the IoT device is determined to be a second positional relationship, the second positional relationship is received.
- the relay device only reports the second position relationship.
- the relay device determines that the position relationship between the relay device and the IoT device is the second position relationship
- the relay device receives the second position relationship.
- the apparatus further comprises:

- FIG19 is a block diagram of a communication device (terminal device or network device) according to an embodiment of the present application.
- the communication device may include: a processor 1901 , a receiver 1902 , a transmitter 1903 , a memory 1904 , and a bus 1905 .

首先,对本申请实施例涉及的相关技术进行介绍:
环境物联网:
环境物联网,或称之为Ambient IoT(简称A-IOT),或称之为零功耗物联网,或称之为无源物联网(passive IoT)。环境物联网是指一种新型无线通信网络,它通过使用环境中的能源在很大程度上实现自给自足。它是一个用于连接和自动化大量对象和设备的生态系统,其中每个对象都使用低成本、自供电的传感器节点连接起来形成无线传感器网络。作为供电的关键机制之一,环境物联网依赖于能量收集,从而无需使用电缆为移动设备和智能物体中的电池供电或充电。来自设备、机械和建筑物的振动,周边无线电信号的传播都可用于发电。
相关技术中,A-IOT在第五代(5th Generation,5G)网络下的拓扑结构包括如下几种:
在一些实施例中,拓扑结构1如图1所示。在拓扑结构1中,物联网设备130直接与网络设备110进
行双向通信。网络设备110与物联网设备130之间的通信包括数据和/或信号。需要说明的是,拓扑结构1所示的通信结构中,可能存在由第一网络设备向第一物联网设备发送数据和/或信号,由第二网络设备接收第一物联网设备发送的数据和/或信号,也即是网络设备与物联网设备并不一定是一一对应的。
在一些实施例中,拓扑结构2如图2所示。在拓扑结构2中,物联网设备130与中继设备120进行双向通信。在拓扑结构2中,中继设备120可以是中间节点、集成接入回传(Integrated Access Backhaul,IAB)节点、中继终端、中继器等。中继设备120在网络设备110和物联网设备130之间传输数据和/或信号。

·基于CSI-RS的每个小区的测量结果;
·CSI-RS测量标识符。
在一些实施例中,测量配置包括以下参数:
1.测量对象:终端设备执行测量的对象列表。
a)对频率内和频率间测量,测量对象指示要测量的参考信号的频率/时间位置和子载波间隔。
b)每个服务小区的测量对象的measObjectId由服务小区配置中的servingCellMO指示。
2.报告配置:报告配置列表,其中每个测量对象可以有一个或多个报告配置。每个测量报告配置都包含以下内容:
·报告标准:触发终端设备发送测量报告的标准。这可以是周期的,也可以是基于单个事件的描述。
·参考信号(Reference Signal,RS)类型:终端设备用于波束和小区测量结果的RS(SSB或CSI-RS)。
·报告格式:每个小区和每个波束的数量以及其他相关信息,例如要报告的最大小区数和每个小区的最大波束数。
3.测量标识:测量标识列表,每个测量标识将一个测量对象与一个报告配置链接。通过配置多个测量标识,可以将多个测量对象链接到同一报告配置,也可以将多个报告配置链接到同一测量对象。
在一些实施例中,报告标准包括以下几种:
·事件A1(服务小区的无线信号质量优于第一阈值)
·事件A2(服务小区的无线信号质量低于第二阈值)
·事件A3(邻小区的无线信号质量比服务小区的无线信号质量高出一个偏移量)
·事件A4(邻小区的无线信号质量优于第三阈值)
·事件A5(服务小区的无线信号质量低于第四阈值,且邻小区的无线信号质量优于第二阈值)
在一些实施例中,如图4所示,在测量对象满足报告标准的情况下,终端设备向网络设备发送测量报告。该测量报告中包含测量标识(measID)、测量结果等信息。
无线射频识别(Radio Frequency Identification,RFID)查询过程:
在一些实施例中,RFID查询过程包括如下步骤:
步骤1:阅读器(Interrogator)通过选择(select)信令选择指定群体或特定群体。在一些实施例中,阅读器也可以称为读出装置或扫描器或通讯器或读写器。在一些实施例中,指定群体可以理解为由选择(select)信令从多个终端设备中选择的部分指定终端设备。在一些实施例中,特定群体可以理解为由选择(select)信令从多个终端设备中选择的部分特定终端设备。
步骤2:阅读器(Interrogator)在间隔一定时间后发送查询(Query)消息。在一些实施例中,查询(Query)消息中包括指定群体或指定终端设备或特定群体或者特定终端设备被选择,还包括时隙计数参数Q。
步骤3:电子标签(Tag)在接收到的(0,2Q-1)中随机选择一个数值,放置到时隙计数器中。选到数值为0的电子标签(Tag)在间隔一定时间后向网络设备发送RN16。
步骤4:网络设备如果正确接收到RN16,则发送确认(Acknowledgement,ACK)命令给电子标签(Tag)。
步骤5:电子标签(Tag)向网络设备发送tag ID信息。
步骤6:网络设备向终端设备发送QueryRep信息。之后,回到步骤2重复执行上述步骤。
在一些实施例中,上述阅读器(Interrogator)可以理解为中继设备,电子标签(Tag)可以理解为物联网设备。
在一些实施例中,上述图1至图3中分别示出了本申请实施例提供的通信系统的不同拓扑结构示意图。本申请实施例中以图2所示的通信系统为例进行说明。该通信系统包括网络设备110、中继设备120和物联网设备130。

本申请中的中继设备120,也可以称为终端设备,也可以称为中间节点(Intermediate Node)。该中继设备120也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置。该中继设备120包括但不限于:手持设备、可穿戴设备、车载设备和物联网设备等,例如:手机、平板电脑、电子书阅读器、膝上便携计算机、台式计算机、电视机、游戏机、移动互联网设备(Mobile Internet Device,MID)、增强现实(Augmented Reality,AR)终端、虚拟现实(Virtual Reality,VR)终端和混合现实(Mixed Reality,MR)终端、可穿戴设备、手柄、电子标签、控制器、工业控制(Industrial Control)中的无线终端、自动驾驶(Self Driving)中的无线终端、远程医疗(Remote Medical)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety)中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端、远程手术(Remote Medical Surgery)中的无线终端、蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)、电视机顶盒(Set Top Box,STB)、用户驻地设备(Customer Premise Equipment,CPE)等。
中继设备120与网络设备110之间通过某种空口技术互相通信,例如Uu接口。示例性的,中继设备120与网络设备110之间存在两种通信场景:上行通信场景与下行通信场景。其中,上行通信是指中继设备120向网络设备110发送信号;下行通信是指网络设备110向中继设备120发送信号。
本申请中的物联网设备130,也可以称为Ambient IoT设备,也可以称为零功耗设备。相关技术中,中继设备120与物联网设备130之间存在双向通信。中继设备120向物联网设备130发送载波,以及向物联网设备130发送数据和/或信号,以及接收物联网设备130反射的数据和/或信号。在一些实施例中,本
申请中的物联网设备130可以理解为上述电子标签(Tag)。
在一些实施例中,在中继设备120移动时,物联网设备130可能是和中继设备120一起移动的,也可能是和中继设备120分开移动的。如何判断中继设备和物联网设备是否是一起移动的,是尚未解决的技术问题。针对上述问题,本申请实施例中提出了一种位置关系的确定方法,能够确定中继设备和物联网设备之间的位置关系。
图5示出了本申请一个示例性实施例提供的位置关系的确定方法的流程图。该方法由中继设备执行。该方法包括:
步骤220:确定中继设备和物联网设备之间的位置关系。
在一些实施例中,中继设备和物联网设备之间位置关系包括如下两种:
·第一位置关系;
·第二位置关系。
在一些实施例中,中继设备和物联网设备之间的位置关系包括第一位置关系。第一位置关系用于指示中继设备与物联网设备之间存在地理捆绑关系。在一些实施例中,地理捆绑关系,也可以称为移动捆绑关系,也可以称为相对位置不变关系。本申请实施例中,以地理捆绑关系为例进行说明。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,理解为在中继设备移动时,物联网设备是跟随中继设备的移动进行移动的。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备的相对位置基本保持不变。示例性的,如图6所示,假设中继设备120在第一时刻处于第一位置,与中继设备120存在地理捆绑关系的物联网设备130在第一时刻处于第一跟随位置,则在中继设备120从第一位置移动至第二时刻所在的第二位置的情况下,物联网设备130也从第一跟随位置移动至第二时刻所在的第二跟随位置。需要理解的是,中继设备120在第一时刻下与物联网设备130之间的第一相对位置(第一位置与第一跟随位置之间的相对位置),与中继设备120在第二时刻下与物联网设备130之间的第二相对位置(第二位置与第二跟随位置之间的相对位置)基本相同。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为物联网设备始终在中继设备的信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终存在连接关系,且该连接关系不随中继设备和/或物联网设备的位置变化而变化。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备之间始终存在连接关系。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终可以进行通信或数据传输或执行查询-响应流程。在一些实施例中,如图7所示,查询-响应流程是指由中继设备向物联网设备发送查询消息,物联网设备基于接收到的查询消息向中继设备反馈响应查询消息的响应消息。
值得说明的是,在一般情况下,在中继设备与物联网设备之间存在地理捆绑关系时,中继设备和物联网设备的距离较近。
在一些实施例中,中继设备和物联网设备之间的位置关系包括第二位置关系。第二位置关系用于指示中继设备与物联网设备之间不存在地理捆绑关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,理解为在中继设备移动时,物联网设备不跟随中继设备的移动进行移动。也即是,中继设备的移动行为和物联网设备的移动行为是分开的,中继设备的移动行为和物联网设备的移动行为不存在相关性。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为物联网设备在第一时刻在中继设备的信号覆盖范围内,在第二时刻不在中继设备的信号覆盖范围内。中继设备在第一时刻在第一位置,在第二时刻在第二位置。需要理解的是,中继设备的信号覆盖范围通常是以中继设备为中心的固定大小的范围。示例性的,如图6所示,假设中继设备120的信号覆盖范围是以中继设备120为圆心的圆形范围,则在中继设备120从第一位置移动至第二位置后,中继设备120的信号覆盖范围仍是以中继设备120为圆心的圆形范围,圆心的位置发生变化,也即中继设备120的位置发生变化,但圆形范围的大小和形状是不变的。或理解为,物联网设备在历史时刻在中继设备的历史信号覆盖范围内,在当前时刻不在中继设备的当前信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备与物联网设备之间在第一时刻存在连接关系,在第二时刻不存在连接关系。或理解为,中继设备与物联网设备之间存在历史连接关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备在第一时刻与物联网设备之间可以进行通信或数据传输或执行查询-响应流程,在第二时刻无法进行行通信或数
据传输或执行查询-响应流程。或理解为,中继设备与物联网设备之间存在历史通信或历史数据传输或历史执行查询-响应流程。
在一些实施例中,确定中继设备和物联网设备之间的位置关系的方法包括如下至少之一:
方法一:基于物联网设备上报的测量报告,确定中继设备和物联网设备之间的位置关系。
方法二:基于是否接收到物联网设备反馈的响应消息,确定中继设备和物联网设备之间的位置关系。
综上所述,本实施例提供的方法,通过确定中继设备和物联网设备之间的位置关系,使得能够确定中继设备与物联网设备之间是否存在地理捆绑关系,从而能够在中继设备与物联网设备不存在地理捆绑关系的情况下,由网络设备及时为物联网设备提供可以替代的中继设备。
针对方法一(测量报告):
图8示出了本申请一个示例性实施例提供的位置关系的确定方法的流程图。该方法由中继设备执行。上述步骤220可替换为如下子步骤:
步骤221:基于物联网设备上报的测量报告,确定中继设备和物联网设备之间的位置关系。
在一些实施例中,该测量报告用于指示物联网设备测量得到的无线信号质量。
在一些实施例中,该测量报告用于指示物联网设备测量得到的无线信号质量小于无线信号质量阈值。在一些实施例中,该无线信号质量阈值用于指示物联网设备测量得到的无线信号质量所允许的最小值。若物联网设备测量得到的无线信号质量小于该最小值,则物联网设备向中继设备上报测量报告;若物联网设备测量的得到的无线信号质量大于或等于该最小值,则物联网设备不向中继设备上报测量报告。在一些实施例中,该无线信号质量阈值是网络设备预配置或预定义的。在一些实施例中,该无线信号质量阈值与中继设备对应。在一些实施例中,该无线信号质量阈值与中继设备的标识是一一对应的。比如,无线信号质量阈值1对应中继设备1,无线信号质量阈值2对应中继设备2。在一些实施例中,该无线信号质量阈值是基于历史测量结果确定的。
在一些实施例中,物联网设备评估无线信号质量的方式包括一种或多种。在一些实施例中,物联网设备基于参考信号的参考信号接收功率(Reference Signal Receiving Power,RSRP)来评估无线信号质量。在一些实施例中,物联网设备基于参考信号的参考信号接收质量(Reference Signal Receiving Quality,RSRQ)来评估无线信号质量。在一些实施例中,物联网设备基于参考信号的信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)来评估无线信号质量。可选的,该参考信号为SSB。可选的,该参考信号为CSI-RS。
在一些实施例中,上述方法还包括:接收物联网设备上报的测量报告。
本申请实施例所提供的方法,通过参考物联网设备上报的测量报告,从而能够使中继设备及时判断和物联网设备之间的位置关系是第一位置关系还是第二位置关系。在物联网设备上报的测量报告指示中继设备与物联网设备之间是第二位置关系时,能够及时由网络设备为物联网设备提供可以替代的中继设备。
针对测量报告是用于指示无线信号质量的:
在一些实施例中,如图9所示,上述步骤221可替换为如下子步骤:
步骤2211:基于物联网设备上报的第一测量报告和第二测量报告,确定中继设备和物联网设备之间的位置关系。
在一些实施例中,第一测量报告和第二测量报告是物联网设备在不同时刻上报的。比如第一测量报告是物联网设备在第一时刻向中继设备上报的,第二测量报告是物联网设备在第二时刻向中继设备上报的。
在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一无线信号质量,第二测量报告用于指示物联网设备在第二时刻测量得到的第二无线信号质量。需要理解的是,第一无线信号质量和第二无线信号质量对应相同的评估指标。
在一些实施例中,该评估指标是参考信号的RSRP。在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一RSRP,第二测量报告用于指示物联网设备在第二时刻测量得到的第二RSRP。第一RSRP和第二RSRP相同或不同。
在一些实施例中,该评估指标是参考信号的RSRQ。在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一RSRQ,第二测量报告用于指示物联网设备在第二时刻测量得到的第二RSRQ。第一RSRQ和第二RSRQ相同或不同。
在一些实施例中,该评估指标是参考信号的SINR。在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一SINR,第二测量报告用于指示物联网设备在第二时刻测量得到的第二SINR。第一SINR和第二SINR相同或不同。
在一些实施例中,在第一无线信号质量和第二无线信号质量的绝对差值小于第一无线信号质量阈值的情况下,确定中继设备和物联网设备之间的位置关系为第一位置关系。在第一无线信号质量和第二无线信号质量的绝对差值大于或等于第一无线信号质量阈值的情况下,确定中继设备和物联网设备之间的位置关系为第二位置关系。
在一些实施例中,第一无线信号质量阈值用于指示物联网设备在不同时刻下测量得到的无线信号质量所允许的最大差值。若物联网设备在不同时刻下测量得到的无线信号质量的绝对差值在该最大差值以下,则反映物联网设备和中继设备之间的位置关系为第一位置关系;若物联网设备在不同时刻下测量得到的无线信号质量的绝对差值等于或超过该最大差值,则反映物联网设备和中继设备之间的位置关系为第二位置关系。
示例性的,假设第一无线信号质量为-30dbm,第二无线信号质量为-35dbm,第一无线信号质量阈值为10dbm,则第一无线信号质量和第二无线信号质量的绝对差值为5dbm,由于5dbm小于10dbm,则可以确定中继设备和物联网设备之间的位置关系为第一位置关系。
示例性的,假设第一无线信号质量为-30dbm,第二无线信号质量为-80dbm,第一无线信号质量阈值为10dbm,则第一无线信号质量和第二无线信号质量的绝对差值为50dbm,由于50dbm大于10dbm,则可以确定中继设备和物联网设备之间的位置关系为第二位置关系。
在一些实施例中,物联网设备的测量时刻和/或第一无线信号质量阈值是网络设备预配置的。在一些实施例中,第一时刻、第二时刻和第一无线信号质量阈值中的至少之一是网络设备预配置的。
在一些实施例中,上述方法还包括:接收物联网设备上报的第一测量报告和第二测量报告。
在一些实施例中,在第一接收时刻接收物联网设备上报的第一测量报告。需要理解的是,在一般情况下,第一接收时刻稍晚于第一时刻,第一时刻是物联网设备上报第一测量报告的时刻。
在一些实施例中,在第二接收时刻接收物联网设备上报的第二测量报告。需要理解的是,在一般情况下,第二接收时刻稍晚于第二时刻,第二时刻是物联网设备上报第二测量报告的时刻。
综上所述,本实施例提供的方法,通过参考物联网设备在不同时刻上报的测量报告,从而能够使中继设备根据不同测量报告所指示的无线信号质量的绝对差值,判断中继设备和物联网设备之间的位置关系是第一位置关系还是第二位置关系。
针对测量报告是用于指示无线信号质量小于无线信号质量阈值的:
在一些实施例中,如图10所示,上述步骤221可替换为如下子步骤:
步骤2212:基于物联网设备上报的第三测量报告,确定中继设备和物联网设备之间的位置关系。
在一些实施例中,第三测量报告用于指示物联网设备测量得到的第三无线信号质量小于第二无线信号质量阈值。在一些实施例中,第三测量报告是在物联网设备测量得到的第三无线信号质量小于第二无线信号质量阈值的情况下被发送的。在一些实施例中,物联网设备对第三无线信号质量进行测量,只有在第三无线信号质量小于第二无线信号质量阈值的情况下,物联网设备才上报第三测量报告;在第三无线信号质量大于或等于第二无线信号质量阈值的情况下,物联网设备不上报第三测量报告。
在一些实施例中,第二无线信号质量阈值用于指示物联网设备测量得到的无线信号质量所允许的最小值。若物联网设备测量得到的无线信号质量小于该最小值,则物联网设备向中继设备上报测量报告;若物联网设备测量的得到的无线信号质量大于或等于该最小值,则物联网设备不向中继设备上报测量报告。
示例性的,假设第三无线信号质量为-80dbm,无线信号质量阈值为-40dbm,由于-80dbm小于-40dbm,则物联网设备向中继设备上报测量报告。
示例性的,假设第三无线信号质量为-35dbm,无线信号质量阈值为-40dbm,由于-35dbm大于-40dbm,则物联网设备不向中继设备上报测量报告。
在一些实施例中,在接收到第三测量报告的情况下,确定中继设备和物联网设备之间的位置关系为第二位置关系。需要理解的是,在物联网设备不向中继设备上报第三测量报告,也即中继设备未接收到第三测量报告的情况下,默认物联网设备和中继设备之间的位置关系为第一位置关系。
在一些实施例中,上述方法还包括:接收物联网设备上报的第三测量报告。
综上所述,本实施例提供的方法,中继设备根据是否接收物联网设备上报的第三测量报告,从而判断中继设备和物联网设备之间的位置关系是第一位置关系还是第二位置关系。仅在接收到物联网设备上报的第三测量报告的情况下,判断中继设备和物联网设备之间的位置关系为第二位置关系,在一定程度上能够有效节约信令开销。
针对方法二(响应消息):
图11示出了本申请一个示例性实施例提供的位置关系的确定方法的流程图。该方法由中继设备执行。上述步骤220可替换为如下子步骤:
步骤222:基于是否接收到或者是否成功解码物联网设备反馈的响应消息,确定中继设备和物联网设备之间的位置关系。
在一些实施例中,该物联网设备是在历史时间与中继设备通信过的设备。在一些实施例中,物联网设备是中继设备历史通信时所对应的设备,或物联网设备是中继设备历史进行数据传输时所对应的设备,或物联网设备是历史接收到响应消息时所对应的设备。
在一些实施例中,该响应消息是物联网设备基于接收到查询消息,向发送该查询消息的中继设备反馈的。在一些实施例中,该响应消息用于指示物联网设备接收到该查询消息。
需要理解的是,本申请实施例中的物联网设备是在历史时刻基于中继设备发送的查询消息,向中继设备反馈过响应消息的设备。也即,本申请实施例中的物联网设备与中继设备在历史时间内执行过查询-响应流程。在一些实施例中,物联网设备在第一反馈时刻向中继设备反馈过响应消息。
在一些实施例中,在上述步骤222之前,上述方法还包括:发送查询消息。
在一些实施例中,该查询消息是中继设备以广播的形式发送的。在一些实施例中,该查询消息用于查询在中继设备的信号覆盖范围内的物联网设备。
在一些实施例中,上述发送查询消息,还包括:在满足查询条件的情况下,发送查询消息。
在一些实施例中,该查询条件用于指示中继设备发送查询消息的发送时机。在一些实施例中,在发生触发事件的情况下,发送查询消息。该触发事件用于触发中继设备发送查询消息。在一些实施例中,该触发事件是网络设备预配置的,网络设备预先向中继设备配置了触发事件相关的信息。在一些实施例中,触发事件包括如下至少之一:
·第一触发事件;
·第二触发事件;
·第三触发事件;
·第四触发事件。
在一些实施例中,第一触发事件用于指示服务小区的无线信号质量小于第三无线信号质量阈值。服务小区是中继设备当前驻留的小区。在一些实施例中,第三无线信号质量阈值用于指示服务小区的无线信号质量所允许的最小值。若服务小区的无线信号质量小于该最小值,则认为发生第一触发事件,此时则触发中继设备发送查询消息;若服务小区的无线信号质量大于或等于该最小值,则认为未发生第一触发事件。可选的,第一触发事件是A1事件(Event A1)。
示例性的,假设服务小区的无线信号质量为-80dbm,第三无线信号质量阈值为-40dbm,由于-80dbm小于-40dbm,则认为发生第一触发事件,此时则触发中继设备发送查询消息。
示例性的,假设服务小区的无线信号质量为-30dbm,第三无线信号质量阈值为-40dbm,由于-30dbm小于-40dbm,则认为未发生第一触发事件。
在一些实施例中,第二触发事件用于指示目标小区的无线信号质量大于服务小区的无线信号质量与偏移值的和。目标小区是服务小区的邻小区。在一些实施例中,在目标小区的无线信号质量大于服务小区的无线信号质量与偏移值的和的情况下,则认为发生第二触发事件,此时则触发中继设备发送查询消息。在目标小区的无线信号质量小于或等于服务小区的无线信号质量与偏移值的和的情况下,则认为未发生第二触发事件。可选的,第二触发事件是A3事件(Event A3)。
示例性的,假设服务小区的无线信号质量为-80dbm,偏移值为10dbm,目标小区的无线信号质量为-40dbm,由于-40dbm大于-70dbm(-80dbm+10dbm),则认为发生第二触发事件,此时则触发中继设备发送查询消息。
在一些实施例中,第三触发事件用于指示目标小区的无线信号质量大于第四无线信号质量阈值。在一些实施例中,第四无线信号质量阈值用于指示目标小区的无线信号质量所允许的最大值。若目标小区的无线信号质量大于该最大值,则认为发生第三触发事件,此时则触发中继设备发送查询消息。若目标小区的无线信号质量小于或等于该最大值,则认为未发生第三触发事件。可选的,第三触发事件是A4事件(Event A4)。
示例性的,假设目标小区的无线信号质量为-10dbm,第四无线信号质量阈值为-30dbm,由于-10dbm大于-30dbm,则认为发生第三触发事件,此时则触发中继设备发送查询消息。
在一些实施例中,第四触发事件用于指示服务小区的无线信号质量小于第五无线信号质量阈值,且目标小区的无线信号质量大于第五无线信号质量阈值。在服务小区的无线信号质量小于第五无线信号质量阈值,且目标小区的无线信号质量大于第五无线信号质量阈值的情况下,认为发生第四触发事件,此时则触发中继设备发送查询消息。在服务小区的无线信号质量大于或等于第五无线信号质量阈值,和/或,
目标小区的无线信号质量小于或等于第五无线信号质量阈值的情况下,认为未发生第四触发事件。可选的,第四触发事件是A5事件(Event A5)。
本申请实施例提供的方法,中继设备在满足查询条件的情况下,发送查询消息,能够实现在需要查询时才发送查询消息,有利于减少中继设备的资源消耗。
本申请实施例提供的方法,在发生触发事件的情况下,发送查询消息,使中继设备能够及时根据测量得到的无线信号质量的情况,积极发送查询消息以判断中继设备和物联网设备之间的位置关系是第一位置关系还是第二位置关系,从而能够及时将与物联网设备相关的位置关系信息上报给网络设备。
在一些实施例中,触发事件用于指示中继设备执行小区切换或小区重选。在中继设备执行小区切换或小区重选之后,与中继设备进行通信的网络设备将会从当前网络设备切换为目标网络设备,此时与中继设备之间存在第一位置关系的物联网设备会随着中继设备一起移动,也即一起完成小区切换或小区重选,则与中继设备之间存在第一位置关系的物联网设备仍然能通过中继设备获得目标网络设备所提供的网络服务。而与中继设备之间存在第二位置关系的物联网设备不会随着中继设备一起移动,物联网设备也无法通过中继设备获得当前网络设备所提供的网络服务。因此,中继设备在发生触发事件之后,就发送查询消息,有利于及时确定与中继设备之间存在第二位置关系的物联网设备,通过及时向网络设备进行上报,使网络设备能够及时为与中继设备之间存在第二位置关系的物联网设备提供可替代的中继设备,避免出现物联网设备失联的情况。
在一些实施例中,中继设备在发送查询消息之后,则等待接收物联网设备反馈的响应消息。
在一些实施例中,中继设备接收到物联网设备反馈的响应消息。也即,物联网设备接收到中继设备发送的查询消息;且物联网设备基于接收到的查询消息,向中继设备发送了响应消息;且该响应消息被中继设备接收到了。
此时,在接收到物联网设备反馈的响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第一位置关系。该响应消息是物联网设备在第二反馈时刻向中继设备反馈的,第二反馈时刻在第一反馈时刻之后。由于物联网设备在第一反馈时刻和第二反馈时刻均向中继设备反馈了响应消息,因此可以确定中继设备和物联网设备之间的位置关系为第一位置关系。
在一些实施例中,在中继设备接收到物联网设备反馈的响应消息,且成功解码该响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第一位置关系。
在一些实施例中,在中继设备接收到物联网设备反馈的响应消息,但未成功解码该响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第二位置关系。
在一些实施例中,中继设备未接收到物联网设备反馈的响应消息。包括如下几种情况:
情况一:物联网设备未接收到中继设备发送的查询消息,则物联网设备不会向中继设备发送响应消息。
情况二:物联网设备接收到中继设备发送的查询消息,且物联网设备基于接收到的查询消息,向中继设备发送了响应消息;但中继设备未接收到物联网设备发送的响应消息。
此时,在未接收到物联网设备反馈的响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第二位置关系。由于物联网设备仅在第一反馈时刻向中继设备反馈了响应消息,因此可以确定中继设备和物联网设备之间的位置关系为第二位置关系。
需要理解的是,在物联网设备已接收到中继设备发送的查询消息,并向中继设备反馈了响应消息的情况下,中继设备未能接收到该响应消息可能是由于中继设备的信号覆盖范围和物联网设备的信号覆盖范围不同。示例性的,假设中继设备的信号覆盖范围为以中继设备为圆心、半径为100米的圆形范围,物联网设备的信号覆盖范围为以物联网设备为圆心、半径为80米的圆形范围。则当物联网设备处于距离中继设备90米的位置时,物联网设备处于中继设备的信号覆盖范围内,可以接收到中继设备发送的查询消息;但中继设备处于物联网设备的信号覆盖范围之外,无法接收到物联网设备反馈的响应消息。
示例性的,如图12所示,假设与中继设备存在历史通信的物联网设备包括物联网设备1、物联网设备2和物联网设备3,中继设备发送查询消息。其中:
物联网设备1接收到查询消息,并向中继设备反馈响应消息1,中继设备在接收到物联网设备1反馈的响应消息1的情况下,判断物联网设备1与中继设备之间的位置关系为第一位置关系。
物联网设备2接收到查询消息,并向中继设备反馈响应消息2。中继设备未能接收到物联网设备2反馈的响应消息2,因此判断物联网设备2与中继设备之间的位置关系为第二位置关系。
物联网设备3未能接收到查询消息,因此也不会反馈响应消息,则中继设备也无法接收到物联网设备3反馈的响应消息3,因此判断物联网设备3与中继设备之间的位置关系为第二位置关系。
综上所述,本实施例提供的方法,中继设备根据是否能接收到物联网设备反馈的响应消息,判断中继设备和物联网设备之间的位置关系是第一位置关系或第二位置关系。在未接收到物联网设备反馈的响
应消息时,能够及时由网络设备为物联网设备提供可以替代的中继设备。
在一些实施例中,上述方法还包括:在物联网设备中的第一物联网设备所占据的比例大于比例阈值的情况下,向网络设备发送告知信息。
在一些实施例中,第一物联网设备是与中继设备之间的位置关系为第二位置关系的设备。示例性的,如图12所示,第一物联网设备是物联网设备2和物联网设备3。
在一些实施例中,比例阈值用于指示在物联网设备中所允许的第一物联网设备的最大占比。在一些实施例中,比例阈值是网络设备预先设置的。可选的,比例阈值是网络设备通过信令配置的。可选的,比例阈值是网络设备通过广播配置的。
在一些实施例中,上述方法还包括:确定第一物联网设备在物联网设备中的占比。在物联网设备中的第一物联网设备所占据的比例小于或等于比例阈值的情况下,不向网络设备发送告知信息。
示例性的,假设物联网设备的数量为10,第一物联网设备的数量为3,比例阈值为50%,则第一物联网设备在物联网设备中的占比为30%,由于30%小于50%,则不向网络设备发送告知信息。
示例性的,假设物联网设备的数量为10,第一物联网设备的数量为7,比例阈值为50%,则第一物联网设备在物联网设备中的占比为70%,由于70%大于50%,则向网络设备发送告知信息。
在一些实施例中,告知信息是中继设备向网络设备发送的,用于告知网络设备与第一物联网设备相关的信息,包括第一物联网设备的设备标识、第一物联网设备的数量、第一物联网设备与中继设备之间的位置关系信息中的至少一种。
本申请实施例提供的方法,中继设备在发现物联网设备中的第一物联网设备的占比大于比例阈值的情况下,能够及时通过向网络设备发送告知信息以告知网络设备第一物联网设备相关的信息,以使得网络设备能够及时为第一物联网设备提供可以替代的中继设备。
在一些实施例中,上述方法还包括:接收响应消息。
在一些实施例中,该响应消息包括与中继设备存在历史通信的物联网设备反馈的第一响应消息。
在一些实施例中,该响应消息包括第二物联网设备反馈的第二响应消息。第二物联网设备是基于查询消息向中继设备发送响应消息的设备。需要理解的是,第二物联网设备是首次与中继设备进行通信的设备,或理解第二物联网设备是首次与中继设备建立连接关系的设备,或理解第二物联网设备是首次与中继设备一起执行查询-响应流程的设备,或理解为第二物联网设备是首次向中继设备反馈响应消息的设备。
在一些实施例中,上述方法还包括:在接收到第二网络设备反馈的第二响应信息的情况下,确定第二物联网设备对应的连接信息。该连接信息用于指示第二物联网设备与中继设备之间建立有连接关系,或用于指示第二物联网设备与中继设备通信过。
在一些实施例中,上述方法还包括:向网络设备发送第二物联网设备对应的连接信息。
本申请实施例提供的方法,通过向网络设备发送新发现的物联网设备对应的连接信息,使网络设备能够及时获知新发现的物联网设备。
图13示出了本申请一个示例性实施例提供的位置关系的确定方法的流程图。该方法由中继设备执行。上述方法还包括:
步骤320:向网络设备发送位置关系。
在一些实施例中,位置关系携带在目标事件相关的上行RRC信令或非接入层(Non-Access-Stratum,NAS)信令中。在一些实施例中,目标事件包括中继设备所对应的测量事件。中继设备向网络设备上报测量事件对应的测量报告时,在相关的上行RRC信令或NAS信令携带位置关系。在一些实施例中,位置关系携带在测量报告(measurement report)或跟踪区更新(Tracking Area Update,TAU)请求(TAU request)中。
在一些实施例中,向网络设备发送位置关系的方式包括以下两种:
方式一:上报第一位置关系,以及上报第二位置关系;
在一些实施例中,在确定中继设备和物联网设备之间的位置关系为第一位置关系的情况下,向网络设备发送第一位置关系;以及在确定中继设备和物联网设备之间的位置关系为第二位置关系的情况下,向网络设备发送第二位置关系。
方式二:仅上报第二位置关系。
在一些实施例中,在确定中继设备和物联网设备之间的位置关系为第二位置关系的情况下,向网络设备发送第二位置关系。
本申请实施例提供的方法,通过向网络设备发送位置关系,使网络设备能够及时获知物联网设备与中继设备之间的位置关系,从而能够在中继设备与物联网设备不存在地理捆绑关系的情况下,由网络设备及时为物联网设备提供可以替代的中继设备。
图14示出了本申请一个示例性实施例提供的位置关系的确定方法的流程图。该方法由网络设备执行。该方法包括:
步骤420:接收位置关系。
在一些实施例中,该位置关系是中继设备发送的。在一些实施例中,该位置关系是中继设备和物联网设备之间的位置关系。在一些实施例中,该位置关系包括第一位置关系或第二位置关系,第一位置关系用于指示中继设备与物联网设备之间存在地理捆绑关系,第二位置关系用于指示中继设备与物联网设备之间不存在地理捆绑关系。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,理解为在中继设备移动时,物联网设备是跟随中继设备的移动进行移动的。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备的相对位置基本保持不变。示例性的,如图6所示,假设中继设备120在第一时刻处于第一位置,与中继设备120存在地理捆绑关系的物联网设备130在第一时刻处于第一跟随位置,则在中继设备120从第一位置移动至第二时刻所在的第二位置的情况下,物联网设备130也从第一跟随位置移动至第二时刻所在的第二跟随位置。需要理解的是,中继设备120在第一时刻下与物联网设备130之间的第一相对位置(第一位置与第一跟随位置之间的相对位置),与中继设备120在第二时刻下与物联网设备130之间的第二相对位置(第二位置与第二跟随位置之间的相对位置)基本相同。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为物联网设备始终在中继设备的信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终存在连接关系,且该连接关系不随中继设备和/或物联网设备的位置变化而变化。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备之间始终存在连接关系。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终可以进行通信或数据传输或执行查询-响应流程。在一些实施例中,如图7所示,查询-响应流程是指由中继设备向物联网设备发送查询消息,物联网设备基于接收到的查询消息向中继设备反馈响应查询消息的响应消息。
值得说明的是,在一般情况下,在中继设备与物联网设备之间存在地理捆绑关系时,中继设备和物联网设备的距离较近。
在一些实施例中,中继设备和物联网设备之间的位置关系包括第二位置关系。第二位置关系用于指示中继设备与物联网设备之间不存在地理捆绑关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,理解为在中继设备移动时,物联网设备不跟随中继设备的移动进行移动。也即是,中继设备的移动行为和物联网设备的移动行为是分开的,中继设备的移动行为和物联网设备的移动行为不存在相关性。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为物联网设备在第一时刻在中继设备的信号覆盖范围内,在第二时刻不在中继设备的信号覆盖范围内。中继设备在第一时刻在第一位置,在第二时刻在第二位置。需要理解的是,中继设备的信号覆盖范围通常是以中继设备为中心的固定大小的范围。示例性的,如图6所示,假设中继设备120的信号覆盖范围是以中继设备120为圆心的圆形范围,则在中继设备120从第一位置移动至第二位置后,中继设备120的信号覆盖范围仍是以中继设备120为圆心的圆形范围,圆心的位置发生变化,也即中继设备120的位置发生变化,但圆形范围的大小和形状是不变的。或理解为,物联网设备在历史时刻在中继设备的历史信号覆盖范围内,在当前时刻不在中继设备的当前信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备与物联网设备之间在第一时刻存在连接关系,在第二时刻不存在连接关系。或理解为,中继设备与物联网设备之间存在历史连接关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备在第一时刻与物联网设备之间可以进行通信或数据传输或执行查询-响应流程,在第二时刻无法进行行通信或数据传输或执行查询-响应流程。或理解为,中继设备与物联网设备之间存在历史通信或历史数据传输或历史执行查询-响应流程。
在一些实施例中,中继设备既上报第一位置关系,又上报第二位置关系。在中继设备确定和物联网设备之间的位置关系为第一位置关系的情况下,接收第一位置关系;以及在中继设备确定和物联网设备
之间的位置关系为第二位置关系的情况下,接收第二位置关系。
在一些实施例中,中继设备仅上报第二位置关系。在中继设备确定和物联网设备之间的位置关系为第二位置关系的情况下,接收第二位置关系。
综上所述,本实施例提供的方法,网络设备通过接收中继设备和物联网设备之间的位置关系,使得能够确定中继设备与物联网设备之间是否存在地理捆绑关系,从而能够在中继设备与物联网设备不存在地理捆绑关系的情况下,及时为物联网设备提供可以替代的中继设备。
在一些实施例中,中继设备在小区范围内进行移动,导致物联网设备掉线或无回应(也即中继设备与物联网设备之间的位置关系为第二位置关系)。示例性的,如图15所示,本申请实施例提供了一种位置关系的确定方法。包括如下步骤:
步骤1a:物联网设备向中继设备发送测量报告。
在一些实施例中,物联网设备1没有向中继设备发送测量报告,则物联网设备1未掉线,或物联网设备1与中继设备之间的位置关系没有发生变化。一般情况下,默认物联网设备与中继设备之间的位置关系为第一位置关系。
在一些实施例中,物联网设备2向中继设备发送测量报告。在一些实施例中,该测量报告用于指示物联网设备2掉线或无回应或物联网设备2与中继设备之间的位置关系发生变化,比如从第一位置关系变为第二位置关系。
步骤1b:中继设备和物联网设备之间执行查询-响应流程。
在一些实施例中,中继设备向物联网设备发送查询消息,包括向物联网设备1发送查询消息,以及向物联网设备2发送查询消息。
在一些实施例中,物联网设备基于接收到的查询消息,向中继设备反馈响应消息。在一些实施例中,物联网设备1向中继设备反馈响应消息,且中继设备接收到响应消息,则物联网设备1未掉线或物联网设备1与中继设备之间的位置关系没有发生变化。在一些实施例中,物联网设备2未向中继设备反馈响应消息,则反映物联网设备2掉线或无回应或物联网设备2与中继设备之间的位置关系发生变化。
需要说明的是,上述步骤1a和步骤1b是可选的。在一些实施例中,可以仅执行步骤1a。在一些实施例中,可以仅执行步骤1b。在一些实施例中,可以执行步骤1a和步骤1b,不区分先后顺序。
步骤2:中继设备向网络设备发送位置关系。
在一些实施例中,在中继设备确定物联网设备与中继设备之间的位置关系发生变化的情况下,向网络设备发送用于指示物联网设备与中继设备之间的位置关系发生变化的指示信息,或向网络设备发送第二位置关系。一般情况下,默认网络设备知道的中继设备和物联网设备之间的位置关系为第一位置关系。
在一些实施例中,中继设备在执行小区切换时,导致物联网设备掉线或无回应(也即中继设备与物联网设备之间的位置关系为第二位置关系)。具体步骤可以参考上述步骤1a、步骤1b和步骤2。
在一些实施例中,在存在一定比例的物联网设备掉线或无回应时,中继设备向网络设备发送告知信息。示例性的,如图16所示,假设一共有3个物联网设备,包括物联网设备1、物联网设备2和物联网设备3。中继设备和网络设备之间提前预设了,在掉线或无回应的物联网设备的比例大于50%的情况下,中继设备向网络设备发送告知信息。比如,基于步骤1a和/或步骤1b,确定物联网设备2和物联网设备3掉线或无回应,则执行步骤3,中继设备向网络设备发送告知信息。

在一些实施例中,该测量报告用于指示物联网设备测量得到的无线信号质量。或,在一些实施例中,该测量报告用于指示物联网设备测量得到的无线信号质量小于无线信号质量阈值。
在一些实施例中,物联网设备评估无线信号质量的方式包括一种或多种。在一些实施例中,物联网设备基于参考信号的参考信号接收功率(Reference Signal Receiving Power,RSRP)来评估无线信号质量。在一些实施例中,物联网设备基于参考信号的参考信号接收质量(Reference Signal Receiving Quality,RSRQ)来评估无线信号质量。在一些实施例中,物联网设备基于参考信号的信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)来评估无线信号质量。可选的,该参考信号为SSB。可选的,该参考信号为CSI-RS。

在一些实施例中,第一测量报告和第二测量报告是物联网设备在不同时刻上报的。比如第一测量报告是物联网设备在第一时刻向装置上报的,第二测量报告是物联网设备在第二时刻向装置上报的。
在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一无线信号质量,第二测量报告用于指示物联网设备在第二时刻测量得到的第二无线信号质量。需要理解的是,第一无线信号质量和第二无线信号质量对应相同的评估指标。
在一些实施例中,该评估指标是参考信号的RSRP。在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一RSRP,第二测量报告用于指示物联网设备在第二时刻测量得到的第二RSRP。第一RSRP和第二RSRP相同或不同。
在一些实施例中,该评估指标是参考信号的RSRQ。在一些实施例中,第一测量报告用于指示物联网设备在第一时刻测量得到的第一RSRQ,第二测量报告用于指示物联网设备在第二时刻测量得到的第二RSRQ。第一RSRQ和第二RSRQ相同或不同。

在一些实施例中,第一无线信号质量阈值用于指示物联网设备在不同时刻下测量得到的无线信号质量所允许的最大差值。若物联网设备在不同时刻下测量得到的无线信号质量的绝对差值在该最大差值以下,则反映物联网设备和装置之间的位置关系为第一位置关系;若物联网设备在不同时刻下测量得到的无线信号质量的绝对差值等于或超过该最大差值,则反映物联网设备和装置之间的位置关系为第二位置关系。
示例性的,假设第一无线信号质量为-30dbm,第二无线信号质量为-35dbm,第一无线信号质量阈值为10dbm,则第一无线信号质量和第二无线信号质量的绝对差值为5dbm,由于5dbm小于10dbm,则可以确定装置和物联网设备之间的位置关系为第一位置关系。
示例性的,假设第一无线信号质量为-30dbm,第二无线信号质量为-80dbm,第一无线信号质量阈值为10dbm,则第一无线信号质量和第二无线信号质量的绝对差值为50dbm,由于50dbm大于10dbm,则可以确定装置和物联网设备之间的位置关系为第二位置关系。
在一些实施例中,物联网设备的测量时刻和/或第一无线信号质量阈值是网络设备预配置的。在一些实施例中,第一时刻、第二时刻和第一无线信号质量阈值中的至少之一是网络设备预配置的。

针对测量报告是用于指示无线信号质量小于无线信号质量阈值的:
确定模块1710,还用于基于物联网设备上报的第三测量报告,确定装置和物联网设备之间的位置关系。
在一些实施例中,第三测量报告用于指示物联网设备测量得到的第三无线信号质量小于第二无线信号质量阈值。在一些实施例中,第三测量报告是在物联网设备测量得到的第三无线信号质量小于第二无线信号质量阈值的情况下被发送的。在一些实施例中,物联网设备对第三无线信号质量进行测量,只有在第三无线信号质量小于第二无线信号质量阈值的情况下,物联网设备才上报第三测量报告;在第三无线信号质量大于或等于第二无线信号质量阈值的情况下,物联网设备不上报第三测量报告。
在一些实施例中,第二无线信号质量阈值用于指示物联网设备测量得到的无线信号质量所允许的最小值。若物联网设备测量得到的无线信号质量小于该最小值,则物联网设备向装置上报测量报告;若物联网设备测量的得到的无线信号质量大于或等于该最小值,则物联网设备不向装置上报测量报告。
示例性的,假设第三无线信号质量为-80dbm,无线信号质量阈值为-40dbm,由于-80dbm小于-40dbm,则物联网设备向装置上报测量报告。
示例性的,假设第三无线信号质量为-35dbm,无线信号质量阈值为-40dbm,由于-35dbm大于-40dbm,则物联网设备不向装置上报测量报告。
在一些实施例中,在接收到第三测量报告的情况下,确定装置和物联网设备之间的位置关系为第二位置关系。需要理解的是,在物联网设备不向装置上报第三测量报告,也即装置未接收到第三测量报告的情况下,默认物联网设备和装置之间的位置关系为第一位置关系。

针对方法二(响应消息):
确定模块1710,还用于基于是否接收到或者是否成功解码物联网设备反馈的响应消息,确定装置和物联网设备之间的位置关系。
在一些实施例中,该物联网设备是在历史时间与装置通信过的设备。在一些实施例中,物联网设备是装置历史通信时所对应的设备,或物联网设备是装置历史进行数据传输时所对应的设备,或物联网设备是历史接收到响应消息时所对应的设备。
在一些实施例中,该响应消息是物联网设备基于接收到查询消息,向发送该查询消息的装置反馈的。在一些实施例中,该响应消息用于指示物联网设备接收到该查询消息。
需要理解的是,本申请实施例中的物联网设备是在历史时刻基于装置发送的查询消息,向装置反馈
过响应消息的设备。也即,本申请实施例中的物联网设备与装置在历史时间内执行过查询-响应流程。在一些实施例中,物联网设备在第一反馈时刻向装置反馈过响应消息。
在一些实施例中,上述装置还包括:
发送模块1730,用于发送查询消息。
在一些实施例中,该查询消息是装置以广播的形式发送的。在一些实施例中,该查询消息用于查询在装置的信号覆盖范围内的物联网设备。
发送模块1730,还用于在满足查询条件的情况下,发送查询消息。
在一些实施例中,该查询条件用于指示装置发送查询消息的发送时机。在一些实施例中,在发生触发事件的情况下,发送查询消息。该触发事件用于触发装置发送查询消息。在一些实施例中,该触发事件是网络设备预配置的,网络设备预先向装置配置了触发事件相关的信息。在一些实施例中,触发事件包括如下至少之一:
·第一触发事件;
·第二触发事件;
·第三触发事件;
·第四触发事件。
在一些实施例中,第一触发事件用于指示服务小区的无线信号质量小于第三无线信号质量阈值。服务小区是装置当前驻留的小区。在一些实施例中,第三无线信号质量阈值用于指示服务小区的无线信号质量所允许的最小值。若服务小区的无线信号质量小于该最小值,则认为发生第一触发事件,此时则触发装置发送查询消息;若服务小区的无线信号质量大于或等于该最小值,则认为未发生第一触发事件。可选的,第一触发事件是A1事件(Event A1)。
示例性的,假设服务小区的无线信号质量为-80dbm,第三无线信号质量阈值为-40dbm,由于-80dbm小于-40dbm,则认为发生第一触发事件,此时则触发装置发送查询消息。
示例性的,假设服务小区的无线信号质量为-30dbm,第三无线信号质量阈值为-40dbm,由于-30dbm小于-40dbm,则认为未发生第一触发事件。
在一些实施例中,第二触发事件用于指示目标小区的无线信号质量大于服务小区的无线信号质量与偏移值的和。目标小区是服务小区的邻小区。在一些实施例中,在目标小区的无线信号质量大于服务小区的无线信号质量与偏移值的和的情况下,则认为发生第二触发事件,此时则触发装置发送查询消息。在目标小区的无线信号质量小于或等于服务小区的无线信号质量与偏移值的和的情况下,则认为未发生第二触发事件。可选的,第二触发事件是A3事件(Event A3)。
示例性的,假设服务小区的无线信号质量为-80dbm,偏移值为10dbm,目标小区的无线信号质量为-40dbm,由于-40dbm大于-70dbm(-80dbm+10dbm),则认为发生第二触发事件,此时则触发装置发送查询消息。
在一些实施例中,第三触发事件用于指示目标小区的无线信号质量大于第四无线信号质量阈值。在一些实施例中,第四无线信号质量阈值用于指示目标小区的无线信号质量所允许的最大值。若目标小区的无线信号质量大于该最大值,则认为发生第三触发事件,此时则触发装置发送查询消息。若目标小区的无线信号质量小于或等于该最大值,则认为未发生第三触发事件。可选的,第三触发事件是A4事件(Event A4)。
示例性的,假设目标小区的无线信号质量为-10dbm,第四无线信号质量阈值为-30dbm,由于-10dbm大于-30dbm,则认为发生第三触发事件,此时则触发装置发送查询消息。
在一些实施例中,第四触发事件用于指示服务小区的无线信号质量小于第五无线信号质量阈值,且目标小区的无线信号质量大于第五无线信号质量阈值。在服务小区的无线信号质量小于第五无线信号质量阈值,且目标小区的无线信号质量大于第五无线信号质量阈值的情况下,认为发生第四触发事件,此时则触发装置发送查询消息。在服务小区的无线信号质量大于或等于第五无线信号质量阈值,和/或,目标小区的无线信号质量小于或等于第五无线信号质量阈值的情况下,认为未发生第四触发事件。可选的,第四触发事件是A5事件(Event A5)。
在一些实施例中,装置在发送查询消息之后,则等待接收物联网设备反馈的响应消息。
在一些实施例中,装置接收到物联网设备反馈的响应消息。也即,物联网设备接收到装置发送的查询消息;且物联网设备基于接收到的查询消息,向装置发送了响应消息;且该响应消息被装置接收到了。
此时,在接收到物联网设备反馈的响应消息的情况下,确定装置和物联网设备之间的位置关系为第一位置关系。该响应消息是物联网设备在第二反馈时刻向装置反馈的,第二反馈时刻在第一反馈时刻之后。由于物联网设备在第一反馈时刻和第二反馈时刻均向装置反馈了响应消息,因此可以确定装置和物联网设备之间的位置关系为第一位置关系。
在一些实施例中,在中继设备接收到物联网设备反馈的响应消息,且成功解码该响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第一位置关系。
在一些实施例中,在中继设备接收到物联网设备反馈的响应消息,但未成功解码该响应消息的情况下,确定中继设备和物联网设备之间的位置关系为第二位置关系。
在一些实施例中,装置未接收到物联网设备反馈的响应消息。包括如下几种情况:
情况一:物联网设备未接收到装置发送的查询消息,则物联网设备不会向装置发送响应消息。
情况二:物联网设备接收到装置发送的查询消息,且物联网设备基于接收到的查询消息,向装置发送了响应消息;但装置未接收到物联网设备发送的响应消息。
此时,在未接收到物联网设备反馈的响应消息的情况下,确定装置和物联网设备之间的位置关系为第二位置关系。由于物联网设备仅在第一反馈时刻向装置反馈了响应消息,因此可以确定装置和物联网设备之间的位置关系为第一位置关系。
示例性的,如图12所示,假设与装置存在历史通信的物联网设备包括物联网设备1、物联网设备2和物联网设备3,装置发送查询消息。其中:
物联网设备1接收到查询消息,并向装置反馈响应消息1,装置在接收到物联网设备1反馈的响应消息1的情况下,判断物联网设备1与装置之间的位置关系为第一位置关系。
物联网设备2接收到查询消息,并向装置反馈响应消息2。装置未能接收到物联网设备2反馈的响应消息2,因此判断物联网设备2与装置之间的位置关系为第二位置关系。
物联网设备3未能接收到查询消息,因此也不会反馈响应消息,则装置也无法接收到物联网设备3反馈的响应消息3,因此判断物联网设备3与装置之间的位置关系为第二位置关系。
发送模块1730,还用于在物联网设备中的第一物联网设备所占据的比例大于比例阈值的情况下,向网络设备发送告知信息。
在一些实施例中,第一物联网设备是与装置之间的位置关系为第二位置关系的设备。示例性的,如图12所示,第一物联网设备是物联网设备2和物联网设备3。
在一些实施例中,比例阈值用于指示在物联网设备中所允许的第一物联网设备的最大占比。在一些实施例中,比例阈值是网络设备预先设置的。可选的,比例阈值是网络设备通过信令配置的。可选的,比例阈值是网络设备通过广播配置的。
确定模块1710,还用于确定第一物联网设备在物联网设备中的占比。在物联网设备中的第一物联网设备所占据的比例小于或等于比例阈值的情况下,不向网络设备发送告知信息。
示例性的,假设物联网设备的数量为10,第一物联网设备的数量为3,比例阈值为50%,则第一物联网设备在物联网设备中的占比为30%,由于30%小于50%,则不向网络设备发送告知信息。
示例性的,假设物联网设备的数量为10,第一物联网设备的数量为7,比例阈值为50%,则第一物联网设备在物联网设备中的占比为70%,由于70%大于50%,则向网络设备发送告知信息。
在一些实施例中,告知信息是装置向网络设备发送的,用于告知网络设备与第一物联网设备相关的信息,包括第一物联网设备的设备标识、第一物联网设备的数量、第一物联网设备与装置之间的位置关系信息中的至少一种。
接收模块1720,还用于接收响应消息。
在一些实施例中,该响应消息包括与装置存在历史通信的物联网设备反馈的第一响应消息。
在一些实施例中,该响应消息包括第二物联网设备反馈的第二响应消息。第二物联网设备是基于查询消息向装置发送响应消息的设备。需要理解的是,第二物联网设备是首次与装置进行通信的设备,或理解第二物联网设备是首次与装置建立连接关系的设备,或理解第二物联网设备是首次与装置一起执行查询-响应流程的设备,或理解为第二物联网设备是首次向装置反馈响应消息的设备。
确定模块1710,还用于在接收到第二网络设备反馈的第二响应信息的情况下,确定第二物联网设备对应的连接信息。该连接信息用于指示第二物联网设备与装置之间建立有连接关系,或用于指示第二物联网设备与装置通信过。
发送模块1730,还用于向网络设备发送第二物联网设备对应的连接信息。
发送模块1730,还用于向网络设备发送位置关系。
在一些实施例中,位置关系携带在目标事件相关的上行RRC信令或NAS信令中。在一些实施例中,目标事件包括装置所对应的测量事件。装置向网络设备上报测量事件对应的测量报告时,在相关的上行RRC信令或非接入层(Non-Access-Stratum,NAS)信令携带位置关系。
在一些实施例中,向网络设备发送位置关系的方式包括以下两种:
方式一:上报第一位置关系,以及上报第二位置关系;
在一些实施例中,在确定装置和物联网设备之间的位置关系为第一位置关系的情况下,向网络设备
发送第一位置关系;以及在确定装置和物联网设备之间的位置关系为第二位置关系的情况下,向网络设备发送第二位置关系。
方式二:仅上报第二位置关系。
在一些实施例中,在确定装置和物联网设备之间的位置关系为第二位置关系的情况下,向网络设备发送第二位置关系。
图18示出了本申请一个示例性实施例提供的位置关系的确定装置的结构框图。该装置包括:
接收模块1810,用于接收位置关系。
在一些实施例中,该位置关系是中继设备发送的。在一些实施例中,该位置关系是中继设备和物联网设备之间的位置关系。在一些实施例中,该位置关系包括第一位置关系或第二位置关系,第一位置关系用于指示中继设备与物联网设备之间存在地理捆绑关系,第二位置关系用于指示中继设备与物联网设备之间不存在地理捆绑关系。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,理解为在中继设备移动时,物联网设备是跟随中继设备的移动进行移动的。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备的相对位置基本保持不变。示例性的,如图6所示,假设中继设备120在第一时刻处于第一位置,与中继设备120存在地理捆绑关系的物联网设备130在第一时刻处于第一跟随位置,则在中继设备120从第一位置移动至第二时刻所在的第二位置的情况下,物联网设备130也从第一跟随位置移动至第二时刻所在的第二跟随位置。需要理解的是,中继设备120在第一时刻下与物联网设备130之间的第一相对位置(第一位置与第一跟随位置之间的相对位置),与中继设备120在第二时刻下与物联网设备130之间的第二相对位置(第二位置与第二跟随位置之间的相对位置)基本相同。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为物联网设备始终在中继设备的信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终存在连接关系,且该连接关系不随中继设备和/或物联网设备的位置变化而变化。也即是,在中继设备和/或物联网设备发生位置移动时,中继设备和物联网设备之间始终存在连接关系。
在一些实施例中,中继设备与物联网设备之间存在地理捆绑关系,还可以理解为中继设备与物联网设备之间始终可以进行通信或数据传输或执行查询-响应流程。在一些实施例中,如图7所示,查询-响应流程是指由中继设备向物联网设备发送查询消息,物联网设备基于接收到的查询消息向中继设备反馈响应查询消息的响应消息。
值得说明的是,在一般情况下,在中继设备与物联网设备之间存在地理捆绑关系时,中继设备和物联网设备的距离较近。
在一些实施例中,中继设备和物联网设备之间的位置关系包括第二位置关系。第二位置关系用于指示中继设备与物联网设备之间不存在地理捆绑关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,理解为在中继设备移动时,物联网设备不跟随中继设备的移动进行移动。也即是,中继设备的移动行为和物联网设备的移动行为是分开的,中继设备的移动行为和物联网设备的移动行为不存在相关性。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为物联网设备在第一时刻在中继设备的信号覆盖范围内,在第二时刻不在中继设备的信号覆盖范围内。中继设备在第一时刻在第一位置,在第二时刻在第二位置。需要理解的是,中继设备的信号覆盖范围通常是以中继设备为中心的固定大小的范围。示例性的,如图6所示,假设中继设备120的信号覆盖范围是以中继设备120为圆心的圆形范围,则在中继设备120从第一位置移动至第二位置后,中继设备120的信号覆盖范围仍是以中继设备120为圆心的圆形范围,圆心的位置发生变化,也即中继设备120的位置发生变化,但圆形范围的大小和形状是不变的。或理解为,物联网设备在历史时刻在中继设备的历史信号覆盖范围内,在当前时刻不在中继设备的当前信号覆盖范围内。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备与物联网设备之间在第一时刻存在连接关系,在第二时刻不存在连接关系。或理解为,中继设备与物联网设备之间存在历史连接关系。
在一些实施例中,中继设备与物联网设备之间不存在地理捆绑关系,还可以理解为中继设备在第一时刻与物联网设备之间可以进行通信或数据传输或执行查询-响应流程,在第二时刻无法进行行通信或数据传输或执行查询-响应流程。或理解为,中继设备与物联网设备之间存在历史通信或历史数据传输或历史执行查询-响应流程。
在一些实施例中,中继设备既上报第一位置关系,又上报第二位置关系。在中继设备确定和物联网
设备之间的位置关系为第一位置关系的情况下,接收第一位置关系;以及在中继设备确定和物联网设备之间的位置关系为第二位置关系的情况下,接收第二位置关系。
在一些实施例中,中继设备仅上报第二位置关系。在中继设备确定和物联网设备之间的位置关系为第二位置关系的情况下,接收第二位置关系。
