在一些情况下，物联网设备通常由于寿命有限的传统电池驱动，这对用户体验产生负面影响。物联网网络设备的数量逐步会呈现天文增长，加上大量物联网设备的出现，将包括劳动力和电池成本在内的维护支出推到了一个全新的水平。每年有数十亿的传统电池被丢弃，只有一小部分可以有效回收，这对地球生态系统造成了有害影响。在一些极端的环境条件下，维持物联网网络的运行和更换电池可能非常具有挑战性。在这方面，已经提出了无电池物联网通信，可将提高网络性能和可持续性，并扩展应用场景。此外，无电池通信对孩子和老人来说更环保、更安全。通过去除传统电池，可以显著降低设备尺寸和成本，从而为各种新的应用铺平道路。In some cases, IoT devices are often driven by traditional batteries with limited lifespans, which negatively impacts the user experience. The astronomical growth in the number of IoT network devices, coupled with the emergence of a large number of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded every year, and only a small portion can be effectively recycled, which has a harmful impact on the earth's ecosystem. In some extreme environmental conditions, it can be very challenging to maintain the operation of IoT networks and replace batteries. In this regard, battery-free IoT communications have been proposed to improve network performance and sustainability and expand application scenarios. In addition, battery-free communications are more environmentally friendly and safer for children and the elderly. By removing traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

在一些实施例中，已经开发了各种低功耗广域(Low Power Wide Area，LPWA)技术，如及其类型通信(Machine Type Communication，MTC)、窄带物联网(Narrow Band Internet of Things，NB-IoT)、能力缩减(Reduced Capability，RedCap)等，以满足垂直领域日益增长的需求。这些LPWA技术实现了低成本、低功耗和大规模连接，可以满足许多应用的要求。然而，仍有许多用例和应用程序在以下情况下无法解决。首先，电池驱动的装置不适用，例如在极端环境条件下(例如高压、极高/低温、潮湿环境)。其次，需要免维护设备(例如，无需更换设备的传统电池)。最后，需要超低的复杂性、非常小的器件尺寸/形状因子(例如mm的厚度)、更长的寿命周期等。In some embodiments, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), Reduced Capability (RedCap), etc., have been developed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, battery-driven devices are not applicable, such as in extreme environmental conditions (e.g., high voltage, extremely high/low temperature, humid environment). Second, maintenance-free devices are required (e.g., traditional batteries that do not need to be replaced in the device). Finally, ultra-low complexity, very small device size/form factor (e.g., mm thickness), longer life cycle, etc. are required.

支持环境电力的物联网是一种很有前途的技术，可以满足上述未满足的需求。支持环境电力的物联网设备是一种由能量收集供电的物联网装置，无电池或能量存储能力有限(例如使用电容器)，通过收集无线电波、光、运动、热量或任何其他合适的电源来提供能量。Ambient-powered IoT is a promising technology that can meet the above unmet needs. An ambient-powered IoT device is an IoT device powered by energy harvesting, either without batteries or with limited energy storage capabilities (e.g. using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

从环境获取的能量可驱动感知节点数据传输和无线通信，当前主流的低功耗物联网通信芯片(如BLE、LoRa、NB-IoT)的收发功耗都在数十毫瓦甚至数百毫瓦级别，而环境能量采集获取能量仅有微瓦级，无法驱动这些类型节点工作，因此需要全新的无线通信技术，使通信能耗下降至数十微瓦甚至十微瓦以下，目前主流的方式采用反向散射通信技术。反向散射通信(Backscatter Communications)是构建绿色节能、低成本、可灵活部署的未来物联网的关键技术之一，是实现“万物智联”的重要手段。可以采用的方式包括反向散射传输(Backscatter Communications)是技术。The energy obtained from the environment can drive the data transmission and wireless communication of the sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a power consumption of tens or even hundreds of milliwatts for transmission and reception, while the energy obtained by environmental energy harvesting is only at the microwatt level, which cannot drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce the communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "intelligent connection of all things". The methods that can be used include backscatter transmission (Backscatter Communications) is a technology.

如图1B，反向散射传输可以利用射频信号反向散射原理，设计出极低功耗的调制与传输技术。读取器向环境物联网(ambient IoT)设备发送物理层信号。该物理层信号可为脉冲信号等各种交流电信号。在一些实施例中，该物理层信号用于提供环境物联网(ambient IoT)设备发射信号的能量。因此，该物理层信号可以称之为激励信号或触发信号。示例性地，由于激励信号到达环境物联网(ambient IoT)设备时一部分会被反射，而环境物联网(ambient IoT)设备可以按照拟发送信息调整接收天线和阻抗之间的匹配，增强对入射激励信号的反射，并将自身获取的感知数据调制到该反射信号上，完成对数据的发送。这一过程类似于反光镜，相对于其他通信技术，反向散射传输无需复杂的射频结构，减少功率放大器、高精度晶振、双工器、高精度滤波器等器件使用，也不需要复杂的基带处理，因此，能够简化环境物联网(ambient IoT)设备设计，大幅降低环境物联网(ambient IoT)设备节点成本。环境物联网(ambient IoT)设备为使用环境能工作的IoT设备。该环境能可包括前述无线信号的信号能，还可以包括地热能和/或光能等其他环境能力。As shown in FIG1B , backscatter transmission can utilize the principle of backscattering of radio frequency signals to design extremely low power consumption modulation and transmission technology. The reader sends a physical layer signal to the ambient IoT device. The physical layer signal can be various AC signals such as pulse signals. In some embodiments, the physical layer signal is used to provide energy for the ambient IoT device to transmit the signal. Therefore, the physical layer signal can be called an excitation signal or a trigger signal. Exemplarily, since a part of the excitation signal will be reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the information to be sent, enhance the reflection of the incident excitation signal, and modulate the perception data obtained by itself onto the reflected signal to complete the transmission of the data. This process is similar to a reflector. Compared with other communication technologies, backscatter transmission does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, it can simplify the design of ambient IoT devices and greatly reduce the node cost of ambient IoT devices. Ambient IoT devices are IoT devices that use environmental energy to work. The environmental energy may include the signal energy of the aforementioned wireless signals, and may also include other environmental capabilities such as geothermal energy and/or light energy.

这里，向环境物联网(ambient IoT)设备发送物理层信号，触发环境物联网(ambient IoT)设备返回反射信号的设备可以称之为环境物联网(ambient IoT)设备的读取器的锚点。Here, the device that sends a physical layer signal to the ambient IoT device and triggers the ambient IoT device to return a reflected signal can be called the anchor point of the reader of the ambient IoT device.

值得注意的是：环境物联网(ambient IoT)设备是使用反向散射传输机制无线通信的一种设备，在具体实现时还有其他设备可以采用反向散射传输机制进行无线通信。It is worth noting that ambient IoT devices are devices that use the backscatter transmission mechanism for wireless communication. In specific implementations, there are other devices that can also use the backscatter transmission mechanism for wireless communication.

该环境物联网(ambient IoT)设备的锚点或者读取器可以是无线通信网络的网络节点，如接入网设备、中继节点(或称中间节点)、或者终端等等。The anchor point or reader of the ambient IoT device can be a network node of a wireless communication network, such as an access network. Device, relay node (or intermediate node), or terminal, etc.

反向散射传输的网络拓扑架构可以包括以下之一项：The network topology for backscatter transmission can include one of the following:

拓扑架构1：如图1C所示，环境物联网(ambient IoT)设备和接入网设备之间直接进行上行(UpLink，UL)和下行(DownLink，DL)的数据传输；Topology 1: As shown in Figure 1C, uplink (UL) and downlink (DL) data transmission is directly carried out between the ambient IoT device and the access network device;

拓扑架构2：如图1D所示，ambient IoT设备和接入网设备之间间接的进行DL和UL的数据传输；中间存在中间节点(或称为辅助节点)做转发，例如中间节点可以是中继(relay)，集成接入回传(Integrated access Backhaul，IAB)，用户设备(User Equipment，UE)，中继器(repeater，RP)。Topology 2: As shown in Figure 1D, DL and UL data transmission is performed indirectly between ambient IoT devices and access network devices; there are intermediate nodes (or auxiliary nodes) in the middle to forward data. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), user equipment (UE), and repeaters (RP).

拓扑架构3：如图1E所示，ambient IoT设备和接入网设备之间在DL或者UL直接进行数据接收或传输；然后在UL或者DL上存在辅助节点，该辅助节点负责接收或者发送UL或者接收DL数据。例如辅助节点可以是中继(relay)，接入回传一体化(IAB)节点、终端、网络控制的重复器(Network Controlled repeater，NCR)。Topology 3: As shown in Figure 1E, the ambient IoT device and the access network device directly receive or transmit data on the DL or UL. Then there is an auxiliary node on the UL or DL, which is responsible for receiving or sending UL or receiving DL data. For example, the auxiliary node can be a relay, an integrated access backhaul (IAB) node, a terminal, or a network controlled repeater (NCR).

拓扑架构4：如图1E所示，ambient IoT设备和UE之间直接的进行DL和UL的数据接收和传输；UE负责收集数据，并将收集的数据转发给网络侧。Topology 4: As shown in Figure 1E, the ambient IoT device and the UE directly receive and transmit DL and UL data; the UE is responsible for collecting data and forwarding it to the network.

如图1F所示，采用反向散射传输机制进行无线通信的设备可以分为三种类型：As shown in Figure 1F, devices that use the backscatter transmission mechanism for wireless communication can be divided into three types:

设备A：没有能量存储，不能独立生成信号/放大信号，只能进行反向散射传输。Device A: has no energy storage, cannot generate/amplify signals independently, and can only perform backscatter transmission.

设备B：具有能量存储，不能独立生成信号，只能进行反向散射传输。存储能量的使用可以包括对反向散射信号的放大。Device B: has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscatter signal.

设备C：具有能量存储，能独立生成信号，即具有用于传输的有源射频(Radio Frequency，RF)组件。Device C: has energy storage and can generate signals independently, that is, it has active Radio Frequency (RF) components for transmission.

在本公开实施例中，考虑到终端的数量众多，故考虑到覆范围，可也选择终端作为使用反向散射原理通信的设备的锚点或者读取器。In the embodiments of the present disclosure, considering the large number of terminals, the terminals may also be selected as anchor points or readers of devices that communicate using the backscatter principle in consideration of the coverage range.

在一些实施例中，第二基站的基站标识；In some embodiments, a base station identifier of the second base station;

与第二基站相关的小区标识；该第二基站相关的小区标识可包括但不限于第二基站配置的一个或多个小区的小区标识。A cell identifier associated with the second base station; the cell identifier associated with the second base station may include but is not limited to cell identifiers of one or more cells configured by the second base station.

第一任务的任务标识；The task identifier of the first task;

第一设备的设备标识。The device identification of the first device.

此处的第一设备可为前述使用反向散射传输机制进行无线通信的设备。例如，该第一设备可为前述图1F所示的任意一种通信设备。The first device here may be the aforementioned device that uses the backscatter transmission mechanism to perform wireless communication. For example, the first device may be any one of the communication devices shown in the aforementioned FIG. 1F.

在一些实施例中，第二信息包含的基站标识是第二基站的标识，也即第二信息指示的基站标识是第二基站，而非第一基站，则说明终端当前有第二基站分发的第一任务。In some embodiments, the base station identifier included in the second information is the identifier of the second base station, that is, the base station identifier indicated by the second information is the second base station, not the first base station, which means that the terminal currently has the first task distributed by the second base station.

第二信息携带的小区标识是第二基站的小区标识，即第二信息指示第二基站的小区，而非第一基站的小区，则第二信息隐含指示终端当前有第二基站分发的第一任务。The cell identifier carried by the second information is the cell identifier of the second base station, that is, the second information indicates the cell of the second base station, not the cell of the first base station, and the second information implicitly indicates that the terminal currently has the first task distributed by the second base station.

第二信息携带有第一任务的任务标识。第一基站可根据该任务标识确定出第一任务是由自身分配的还是由第二基站分配的。此处的分配也可以理解为分发。The second information carries the task identifier of the first task. The first base station can determine whether the first task is assigned by itself or by the second base station according to the task identifier. The assignment here can also be understood as distribution.

示例性地，任务标识可根据分发第一任务的基站生成，该任务标识可包括基站标识和/或小区标识。任务标识包含的基站标识，指示分发第一任务的基站。任务标识包含的小区标识在，是分发第一任务的基站。Exemplarily, the task identifier may be generated according to the base station that distributes the first task, and the task identifier may include a base station identifier and/or a cell identifier. The base station identifier included in the task identifier indicates the base station that distributes the first task. The cell identifier included in the task identifier is the base station that distributes the first task.

又示例性地，第一任务的任务标识可以由核心网设备或者第二设备来确定。此时，不同的任务具有不同的任务标识。第一基站自身分发的任务，则第一基站本地会存储有对应任务的任务标识。若该任务标识与第一基站本地存储的任务标识不匹配，则说明终端被第二基站配置有第一任务。In another exemplary embodiment, the task identifier of the first task can be determined by the core network device or the second device. At this time, different tasks have different task identifiers. For tasks distributed by the first base station itself, the first base station will locally store the task identifier of the corresponding task. If the task identifier does not match the task identifier stored locally by the first base station, it means that the terminal is configured with the first task by the second base station.

终端作为读取器的设备标识。该设备标识可由第一基站、核心网设备和/或第二设备确定。The terminal is used as a device identifier of a reader. The device identifier may be determined by the first base station, the core network device and/or the second device.

S2104：终端发送第一信息。S2104: The terminal sends the first information.

在一些实施例中，终端向第一基站发送第一信息。In some embodiments, the terminal sends first information to the first base station.

在一些实施例中，终端在第一基站的小区内发送第一信息。In some embodiments, the terminal sends the first information within a cell of the first base station.

在一些实施例中，第一信息与第一任务相关。In some embodiments, the first information is related to the first task.

在第一实施例中，第一信息为终端执行第一任务时从第一设备接收的信息。In the first embodiment, the first information is information received from the first device when the terminal executes the first task.

在一些实施例中，第一基站接收包含第一信息且与小区切换相关的消息。In some embodiments, the first base station receives a message including first information and related to cell switching.

在一些实施例中，第一基站接收包含第一信息且与小区重选相关的消息。 In some embodiments, the first base station receives a message including first information and related to cell reselection.

在一些实施例中，第一基站接收包含第一信息且是终端切换或重选到目标小区之后发送的任意消息。In some embodiments, the first base station receives any message containing the first information and sent by the terminal after switching or reselecting to the target cell.

在另一些实施例中，第一消息可为RRC消息、MAC层消息或者上行控制信息(Uplink Control Information，UCI)。In other embodiments, the first message may be an RRC message, a MAC layer message, or uplink control information (Uplink Control Information, UCI).

在一些实施例中，第一信息和第二信息可由终端不同的消息发送至第一基站，也可以是由相同的消息发送至第一基站。In some embodiments, the first information and the second information may be sent to the first base station by the terminal through different messages, or may be sent to the first base station through the same message.

若第一信息和第二信息由终端的同一条消息发送至第一基站，则步骤S2101以及2104可以合并为同一个步骤。If the first information and the second information are sent to the first base station by the same message of the terminal, steps S2101 and 2104 may be combined into the same step.

若第一信息和第二信息终端的不同消息发送至第一基站，则步骤S2101和S2104为不同的步骤。If different messages of the first information terminal and the second information terminal are sent to the first base station, steps S2101 and S2104 are different steps.

在一些实施例中，终端将收集到的第一信息及时(例如实时)发送给第一基站。In some embodiments, the terminal sends the collected first information to the first base station in a timely manner (eg, in real time).

在另一些实施例中，终端可以缓存第一设备的第一信息，且在未检测到的预设事件时向第一基站发送第一信息。如此在第一基站作为终端的服务基站时，终端没有向第一基站发送第一信息。In some other embodiments, the terminal may cache the first information of the first device, and send the first information to the first base station when no preset event is detected. In this way, when the first base station serves as a serving base station of the terminal, the terminal does not send the first information to the first base station.

该预设事件包括但不限于以下至少之一：The preset event includes but is not limited to at least one of the following:

终端完成收集第一信息关联的第一任务；The terminal completes the first task of collecting the first information;

终端接收到延时敏感的第一信息。The terminal receives delay-sensitive first information.

此处的第一信息的缓存量可为一个或多个第二设备的第一信息的数据总量。The cache amount of the first information here may be the total amount of data of the first information of one or more second devices.

在第一信息的缓存量达到第一阈值时，终端退出非连接态进入到连接态，将缓存的第一信息上报该网络设备。When the cache amount of the first information reaches a first threshold, the terminal exits the non-connected state and enters the connected state, and reports the cached first information to the network device.

在一些情况下，配置了定期或者不定期的上报缓存的第一信息。若达到上报时刻，且终端在飞连接态下缓存有尚未上报的第一信息，则可认为检测到预设事件。In some cases, the first information cached is reported periodically or irregularly. If the reporting time is reached and the terminal has cached first information that has not been reported in the flying connection state, it can be considered that a preset event is detected.

在一些实施中，第一信息的缓存时长比较长了，为了尽可能块的上报，则在缓存时长比较长了，可能存在数据量比较小的情况下，也进入到连接态，以及时将第一信息上报至网络设备侧。In some implementations, the cache time of the first information is relatively long. In order to report it as quickly as possible, even when the cache time is relatively long and the data volume may be relatively small, the connection state is entered to report the first information to the network device side in a timely manner.

在一些情况下，终端缓存一个或多个第一设备的第一信息。示例性地，在缓存多个第一设备的第一信息时，这多个第一设备可为同类型的设备，或者，需要上报同类型数据的设备。In some cases, the terminal caches the first information of one or more first devices. Exemplarily, when caching the first information of multiple first devices, the multiple first devices may be devices of the same type, or devices that need to report data of the same type.

若当前终端缓存的数据量较大，则会使得终端内的缓存空间被占用。当终端的剩余缓存空间逐步减小到一定程度时，例如，减少到小于预设值时，则可认为检测到预设事件。If the amount of data currently cached by the terminal is large, the cache space in the terminal will be occupied. When the remaining cache space of the terminal gradually decreases to a certain extent, for example, when it decreases to less than a preset value, it can be considered that a preset event is detected.

在一些实施例中，终端在接收第二设备发送的第一信息，但发现第一信息的是时延敏感的信息，需要及时上报时，则同样可为检测到预设事件。In some embodiments, when the terminal receives the first information sent by the second device but finds that the first information is delay-sensitive information and needs to be reported in a timely manner, it can also be considered that a preset event is detected.

在另一些实施例中，若终端自身有业务数据待上报，或者，通过监听到系统消息更新，终端需要进入到连接态，则此时终端正好有第一信息待发送，则同样可以在终端基于自身业务数据上报和/或系统消息更新触发的第一消息中发送第一信息，从而顺带告知网络设备当前终端有缓存第一信息。In other embodiments, if the terminal itself has business data to be reported, or, by monitoring the system message update, the terminal needs to enter the connected state, and the terminal happens to have the first information to be sent at this time, the first information can also be sent in the first message triggered by the terminal's own business data reporting and/or system message update, thereby informing the network device that the current terminal has cached the first information.

在终端发送第一信息时，第一基站会收到终端发送的第一信息。When the terminal sends the first information, the first base station will receive the first information sent by the terminal.

S2105：第一基站发送第一信息。S2105: The first base station sends first information.

值得注意的是：图3A所示的各个步骤没有固定的先后顺序，也并非所有的步骤都是必选步骤。It is worth noting that: the steps shown in FIG. 3A have no fixed order, and not all steps are mandatory.

在一些实施例中，第一基站可以顺序执行S3101、S3102、S3103、S3104以及S3105。In some embodiments, the first base station may sequentially execute S3101, S3102, S3103, S3104, and S3105.

在另一些实施例中，第一基站可以顺序执行S3101、S3104、S3102、S3103、以及S3105。In some other embodiments, the first base station may execute S3101, S3104, S3102, S3103, and S3105 sequentially.

在另一些实施例中，第一基站可以顺序执行S3101、S3102、S3104、S3103、以及S3105。In some other embodiments, the first base station may execute S3101, S3102, S3104, S3103, and S3105 sequentially.

在一些实施例中，第一基站可以顺序执行S3101、S3102以及3103，即步骤S3104以及S3105是可选步骤。例如，终端的服务基站更换为第二基站之后，终端可以实时将从第一设备接收的第一信息发送给第一基站，此时S3104和S3105可为需要执行的步骤。但是终端可以缓存第一设备的第一信息，且在未检测到的预设事件时向第一基站发送第一信息。如此在第一基站作为终端的服务基站时，终端没有向第一基站发送第一信息。预设事件相关的描述可参见图2A所示的实施例，此处就不再重复了。In some embodiments, the first base station may sequentially execute S3101, S3102, and 3103, that is, steps S3104 and S3105 are optional steps. For example, after the service base station of the terminal is changed to the second base station, the terminal may send the first information received from the first device to the first base station in real time, and S3104 and S3105 may be steps that need to be executed. However, the terminal may cache the first information of the first device, and send the first information to the first base station when no preset event is detected. In this way, when the first base station serves as the service base station of the terminal, the terminal does not send the first information to the first base station. The description of the preset event can be found in the embodiment shown in Figure 2A, which will not be repeated here.

在另一些实施例中，第一基站可以顺序执行S3104以及S3105，即步骤S3101、S3102以及S3103是可选步骤。第一基站接收到第一信息之后，可以直接将第一信息转发至核心网设备，由核心网设备根据第一信息根据第一终端作为读取器的设备标识和/或第一设备的设备标识等，将第一信息路由至第二设备。或者，第一基站可以从核心网设备获取与第一任务相关的配置信息，如此，无须从第二基站获取与第一任务相关的配置信息。在一些实施例中，S3102可为可选步骤，即直接执行S3103、S3101以及S3105。例如，终端通过小区切换更换到第一基站，第二基站在执行终端的小区切换时，就主动将与第一任务相关的配置信息发送至第一基站。如此，第一基站当前还未作为终端的服务基站，仅仅是作为终端的目标基站，就已经获取了与第一任务相关的配置信息。后续，在接收到第一信息和/或第二信息的情况下，则第一基站查询预先获取的与第一任务相关的配置信息，发送第一信息即可。In other embodiments, the first base station may sequentially execute S3104 and S3105, that is, steps S3101, S3102, and S3103 are optional steps. After receiving the first information, the first base station may directly forward the first information to the core network device, and the core network device routes the first information to the second device according to the first information, the device identification of the first terminal as a reader, and/or the device identification of the first device. Alternatively, the first base station may obtain configuration information related to the first task from the core network device, so that there is no need to obtain configuration information related to the first task from the second base station. In some embodiments, S3102 may be an optional step, that is, directly executing S3103, S3101, and S3105. For example, the terminal is switched to the first base station through cell switching, and the second base station actively sends the configuration information related to the first task to the first base station when executing the cell switching of the terminal. In this way, the first base station has not yet served as a service base station for the terminal, but only as a target base station for the terminal, and has obtained the configuration information related to the first task. Subsequently, when the first information and/or the second information is received, the first base station queries the pre-acquired configuration information related to the first task and sends the first information.

本公开实施例中，第一基站可以协助终端处理第二基站分配给终端的第一任务，从而实现第一任务的顺利执行。In the disclosed embodiment, the first base station may assist the terminal in processing the first task assigned to the terminal by the second base station, thereby achieving smooth execution of the first task.

图3B是根据本公开实施例示出的一种通信方法的示意图。如图3A所示，本公开实施例涉及通信方法，用于第一基站，方法包括：FIG3B is a schematic diagram of a communication method according to an embodiment of the present disclosure.

在一些实施例中，第一基站接收与第一任务相关的配置信息。In some embodiments, the first base station receives configuration information related to the first task.

该S3201的执行可以参见图2B对应实施例的步骤S2201。The execution of S3201 may refer to step S2201 of the embodiment corresponding to FIG. 2B .

此处的与第一任务相关的配置信息可参见图2A和/或图2B对应实施例的相关部分。 The configuration information related to the first task here can refer to the relevant parts of the corresponding embodiments of FIG. 2A and/or FIG. 2B.

在一些实施例中，第一基站接收终端发送的第一信息。In some embodiments, the first base station receives first information sent by the terminal.

在一些实施例中，第一基站接收终端发送包含第一消息的RRC消息、MAC层消息或UCI等。In some embodiments, the first base station receives an RRC message, a MAC layer message or UCI, etc., sent by the terminal and containing the first message.

该第一信息的相关描述可参见图2A和/或图2B所示的任意一个实施例。For the related description of the first information, please refer to any one of the embodiments shown in FIG. 2A and/or FIG. 2B .

在一些实施例中，第一基站向第二基站、核心网设备和/或第二设备发送第一信息。In some embodiments, the first base station sends the first information to the second base station, the core network device and/or the second device.

具体的该S3203的具体实现可图2B对应实施例的S2203，或参见图2A所示实施例的S2105。The specific implementation of S3203 may refer to S2203 of the embodiment corresponding to FIG. 2B , or refer to S2105 of the embodiment shown in FIG. 2A .

值得注意的是：图3B所示的各个步骤没有固定的先后顺序，也并非所有的步骤都是必选步骤。It is worth noting that: the steps shown in FIG. 3B do not have a fixed order, and not all steps are mandatory steps.

在一些实施例中，第一基站可以顺序执行S3201、S3202以及S3103。In some embodiments, the first base station may execute S3201, S3202 and S3103 sequentially.

在另一些实施例中，第一基站可以单独执行S3201，即步骤S3202以及S3203并非必选步骤。In some other embodiments, the first base station may execute S3201 alone, that is, steps S3202 and S3203 are not mandatory steps.

例如，终端的服务基站更换为第二基站之后，终端可以实时将从第一设备接收的第一信息发送给第一基站，此时S3201可为需要执行的步骤。但是终端可以缓存第一设备的第一信息，且在未检测到的预设事件时向第一基站发送第一信息。如此在第一基站作为终端的服务基站时，终端没有向第一基站发送第一信息。For example, after the service base station of the terminal is changed to the second base station, the terminal can send the first information received from the first device to the first base station in real time, and S3201 may be a step that needs to be performed. However, the terminal can cache the first information of the first device and send the first information to the first base station when no preset event is detected. In this way, when the first base station serves as the service base station of the terminal, the terminal does not send the first information to the first base station.

在还有一些实施例中，第一基站执行步骤S3202以及步骤S3103。例如，第一基站收到第一信息之后，直接将第一信息发送至核心网设备，核心网设备存储有第一任务的任务信息，此时，核心网接收到该第一信息之后，将根据该任务信息发送至第二设备。例如，第一任务是由核心网设备配置时，核心网设备会存储第一任务的任务信息。又例如，第一任务是由第二设备配置的，则第二设备配置的第一任务会发布至核心网设备，如此，核心网设备同样会存储第一任务的任务信息。In some other embodiments, the first base station performs step S3202 and step S3103. For example, after receiving the first information, the first base station directly sends the first information to the core network device. The core network device stores the task information of the first task. At this time, after receiving the first information, the core network sends it to the second device according to the task information. For example, when the first task is configured by the core network device, the core network device will store the task information of the first task. For another example, if the first task is configured by the second device, the first task configured by the second device will be published to the core network device. In this way, the core network device will also store the task information of the first task.

在一些情况下，第一任务的任务信息可作为终端的上下文存储在核心网设备，如此，第一基站可以不从第二基站获取与第一任务相关的配置信息，而是从核心网设备请求包含该与第一任务相关的配置信息的上下文。In some cases, the task information of the first task may be stored in the core network device as the context of the terminal. In this way, the first base station may not obtain the configuration information related to the first task from the second base station, but instead request the context containing the configuration information related to the first task from the core network device.

图4A是根据本公开实施例示出的一种通信方法的示意图。如图4A所示，本公开实施例涉及通信方法，用于第二基站，方法包括：FIG4A is a schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG4A , the present disclosure embodiment relates to a communication method for a second base station, the method comprising:

S4101：接收第一消息，其中，第一消息，用于请求第二基站发送与第一任务相关的配置信息。S4101: Receive a first message, where the first message is used to request a second base station to send configuration information related to a first task.

在一些实施例中，接收第二基站发送的第一消息。In some embodiments, a first message sent by a second base station is received.

在一些实施例中，第二基站为给终端分发(分配)第一任务的基站。In some embodiments, the second base station is a base station that distributes (assigns) the first task to the terminal.

在一些实施例中，第二基站可为执行第一任务的终端的前一个或多个服务基站。In some embodiments, the second base station may be one or more previous serving base stations of the terminal performing the first task.

在另一些实施例中，第二基站可为终端源基站。In some other embodiments, the second base station may be a terminal source base station.

该S4101的执行可参见图2A所示实施例的S2102。The execution of S4101 may refer to S2102 of the embodiment shown in FIG. 2A .

此处与第一任务相关的配置信息可包括前述任意一个实施例提供的任务配置信息和/或连接配置信息。The configuration information related to the first task here may include the task configuration information and/or connection configuration information provided by any one of the aforementioned embodiments.

S4102：发送与第一任务相关的配置信息。S4102: Send configuration information related to the first task.

在一些实施例中，向第一基站发送与第一任务相关的配置信息。In some embodiments, configuration information related to the first task is sent to the first base station.

在一些实施例中，与第一任务相关的配置信息，用于第一基站发送第一信息；In some embodiments, the configuration information related to the first task is used for the first base station to send the first information;

在一些实施例中，第二基站接收到第一消息之后，可向第一基站发送与第一任务相关的配置信息。In some embodiments, after receiving the first message, the second base station may send configuration information related to the first task to the first base station.

示例性地，根据第二消息指示的第一任务、第一设备或者终端，确定出待发送至第一基站的与第一任务相关的配置信息。将确定的与第一任务相关的配置信息，发送至第一基站。Exemplarily, according to the first task, the first device or the terminal indicated by the second message, configuration information related to the first task to be sent to the first base station is determined, and the determined configuration information related to the first task is sent to the first base station.

该步骤的具体执行可以参见图2A所示实施例的S2103。For the specific implementation of this step, please refer to S2103 of the embodiment shown in FIG. 2A .

S4103：接收第一信息。S4103: Receive first information.

在一些实施例中，响应于与第一任务相关的配置信息为连接配置信息，则从第一基站接收第一信息。示例性地，使用第一基站和第二基站之间的GTP隧道或者Xn接口或X2接口，接收第一基站发送的第一信息。例如，基于Xn接口从第一基站接收包含第一信息的XnAP消息。Xn application protocol为XnAP的缩写，对应的中文可为Xn应用协议。In some embodiments, in response to the configuration information related to the first task being connection configuration information, the first information is received from the first base station. Exemplarily, the first information sent by the first base station is received using a GTP tunnel or an Xn interface or an X2 interface between the first base station and the second base station. For example, an XnAP message containing the first information is received from the first base station based on the Xn interface. Xn application protocol is the abbreviation of XnAP, and the corresponding Chinese may be Xn application protocol.

S4104：发送第一信息。S4104: Send the first information.

在一些实施例中，第二基站通过与第二设备之间的直连通道，直接向第二设备发送第一信息。In some embodiments, the second base station directly sends the first information to the second device through a direct connection channel between the second base station and the second device.

在另一些实施例中，第二基站可通过与核心网设备之间的通道，向核心网设备发送第一信息，该第一信息再由核心网设备转发至第二设备。In other embodiments, the second base station may send the first information to the core network device through a channel between the second base station and the core network device, and the first information is then forwarded to the second device by the core network device.

第二基站具体如何发送第一信息，可以参见图2A所示的步骤2105相关的内容。 For details on how the second base station sends the first information, please refer to the relevant content of step 2105 shown in FIG. 2A .

值得注意的是：图4A所示的各个步骤没有固定的先后顺序，也并非所有的步骤都是必选步骤。It is worth noting that: the steps shown in FIG. 4A have no fixed order, and not all steps are mandatory steps.

在一些实施例中，第二基站可以顺序执行S4101、S4102、S4103以及S4104。In some embodiments, the second base station may execute S4101, S4102, S4103 and S4104 sequentially.

在另一些实施例中，第二基站可以单独执行S4102，即S4102、S4103以及S4104并非必选步骤。例如，第二基站主动向第一基站发送与第一任务相关的配置信息，则可以省略步骤S4101。且即便将与第一任务相关的配置信息发送至第一基站之后，第一基站未必会收到终端上报的第一信息，则可能S4103以及S4104也是可选步骤。In other embodiments, the second base station may perform S4102 alone, that is, S4102, S4103, and S4104 are not mandatory steps. For example, if the second base station actively sends configuration information related to the first task to the first base station, step S4101 may be omitted. Even if the configuration information related to the first task is sent to the first base station, the first base station may not receive the first information reported by the terminal, so S4103 and S4104 may also be optional steps.

在还有一些实施例中，第二基站可顺序执行S4102以及S4101。即S4103以及S4104是可选步骤。In some other embodiments, the second base station may execute S4102 and S4101 sequentially, that is, S4103 and S4104 are optional steps.

在还有一些实施例中，第二基站可顺序执行S4103以及S4104，即S4101以及S4102都是可选步骤。例如，第一基站可以从核心网设备或者第二设备等其他设备获取到与第一任务相关的任务信息，则第一基站可以在接收到第一信息时，根据连接配置信息向第一基站发送第一信息。In some other embodiments, the second base station may sequentially execute S4103 and S4104, that is, S4101 and S4102 are both optional steps. For example, the first base station may obtain task information related to the first task from other devices such as the core network device or the second device, and the first base station may send the first information to the first base station according to the connection configuration information when receiving the first information.

例如，终端的服务基站更换为第二基站之后，终端可以实时将从第一设备接收的第一信息发送给第一基站，但是终端可以缓存第一设备的第一信息，且在未检测到的预设事件时向第一基站发送第一信息。如此在第一基站作为终端的服务基站时，终端没有向第一基站发送第一信息。如此第二基站也就接收不到第一基站发送的低于信息。For example, after the service base station of the terminal is changed to the second base station, the terminal can send the first information received from the first device to the first base station in real time, but the terminal can cache the first information of the first device and send the first information to the first base station when the preset event is not detected. In this way, when the first base station is the service base station of the terminal, the terminal does not send the first information to the first base station. In this way, the second base station cannot receive the information sent by the first base station.

在一些实施例中，第二基站在向终端分发第一任务的任务信息之前，第二基站可获取到第三信息。该第三信息可用于第二基站选择作为第一设备的读取器的终端。In some embodiments, before the second base station distributes the task information of the first task to the terminal, the second base station may acquire third information. The third information may be used by the second base station to select a terminal as a reader of the first device.

第三信息的相关内容可以参见图2A和/或图2B所示的实施例。第二基站可以选择支持作为第一设备的读取器和/或同意作为第一设备的读取器的终端，执行第一任务。在一些实施例中，第二基站还可以根据终端当前的负载状态、电量状态、温度和/或自身的无线任务等情况下，选择作为第一设备读取器的终端。For the relevant content of the third information, please refer to the embodiments shown in Figure 2A and/or Figure 2B. The second base station can select a terminal that supports the reader of the first device and/or agrees to be the reader of the first device to perform the first task. In some embodiments, the second base station can also select a terminal as the reader of the first device based on the current load status, power status, temperature and/or its own wireless task of the terminal.

图4B是根据本公开实施例示出的一种通信方法的示意图。如图4B所示，本公开实施例涉及通信方法，用于第二基站，方法包括：FIG4B is a schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG4B , the embodiment of the present disclosure relates to a communication method for a second base station, the method comprising:

S4202：发送与第一任务相关的配置信息。S4202: Send configuration information related to the first task.

在一些实施例中，向第一基站发送与小区切换相关的消息，该与小区切换相关的消息可包括但不限于小区切换请求消息。该与小区切换相关的消息包括前述与第一任务相关的配置信息。In some embodiments, a message related to cell switching is sent to the first base station, and the message related to cell switching may include but is not limited to a cell switching request message. The message related to cell switching includes the aforementioned configuration information related to the first task.

S4202：接收第一信息。S4202: Receive first information.

S4203：发送第一信息。S4203: Send the first message.

第二基站具体如何发送第一信息，可以参见图2A所示的步骤2105相关的内容。For details on how the second base station sends the first information, please refer to the relevant content of step 2105 shown in FIG. 2A .

值得注意的是：图4B所示的各个步骤没有固定的先后顺序，也并非所有的步骤都是必选步骤。It is worth noting that: the steps shown in FIG. 4B do not have a fixed order, and not all steps are mandatory steps.

在一些实施例中，第二基站可以顺序执行S4201、S4202以及S4103。In some embodiments, the second base station may execute S4201, S4202 and S4103 sequentially.

在另一些实施例中，第二基站可以单独执行S4101，即S4202以及S4103并非必选步骤。例如，第二基站主动向第一基站发送与第一任务相关的配置信息，则可以省略步骤S4201。且即便将与第一任务相关的配置信息发送至第一基站之后，第一基站未必会收到终端上报的第一信息，则可能S4202以及S4103也是可选步骤。In other embodiments, the second base station may perform S4101 alone, that is, S4202 and S4103 are not mandatory steps. For example, if the second base station actively sends configuration information related to the first task to the first base station, step S4201 may be omitted. Even if the configuration information related to the first task is sent to the first base station, the first base station may not receive the first information reported by the terminal, so S4202 and S4103 may also be optional steps.

在一些实施例中，接收第一设备基于第一信号的信号能量反射的反射信号，该反射信号携带有第一信息。In some embodiments, a reflected signal is received by the first device based on signal energy of the first signal, where the reflected signal carries the first information.

此处的第一信息的接收可以参见图2A对应实施例的相关描述，此处就不在举例了。The reception of the first information here can refer to the relevant description of the embodiment corresponding to Figure 2A, and no example is given here.

S5103：发送第二信息。S5103: Send the second information.

终端向第一基站发送第二信息。The terminal sends second information to the first base station.

在一些实施例中，非连接态的终端在检测到预设事件的情况下，向第一基站发送第二信息。In some embodiments, the terminal in the non-connected state sends the second information to the first base station when a preset event is detected.

在一些实施例中，非连接态终端接收到第一信息之后，确定未检测到预设事件，可先缓存第一信息，等到检测到预设事件之后，向第一基站发送第二信息。In some embodiments, after receiving the first information, the non-connected terminal determines that no preset event is detected, and may cache the first information first, and then send the second information to the first base station after the preset event is detected.

在一些实施例中，非连接态的终端小区重选到第一基站之后，通过与小区重选相关的消息发送第二信息，或者，非连接态终端小区重选到第一基站之后进入到连接态，在终端连接态下时发送携带有第二信息的RRC消息、MAC层消息或者UCI等。In some embodiments, after the terminal cell in a non-connected state reselects to the first base station, the second information is sent via a message related to the cell reselection. Alternatively, after the terminal cell in a non-connected state reselects to the first base station, it enters a connected state, and when in the terminal connected state, an RRC message, a MAC layer message or UCI carrying the second information is sent.

在一些实施例中，前述第二信息可携带在可为终端从非连接态切换到连接态的消息一至消息五中任意一种终端发送的消息。也即第一消息可为消息一、消息三以及消息五中的任意一个。消息一可包括终端发送的随机接入前导码。消息二可为基站发送的随机接入响应。消息四可为RRC连接建立消息。In some embodiments, the aforementioned second information may be carried in any one of messages 1 to 5 sent by the terminal for switching the terminal from a non-connected state to a connected state. That is, the first message may be any one of message 1, message 3 and message 5. Message 1 may include a random access preamble sent by the terminal. Message 2 may be a random access response sent by the base station. Message 4 may be an RRC connection establishment message.

示例性地，携带第一信息的消息可为Msg3和/或Msg5。Exemplarily, the message carrying the first information may be Msg3 and/or Msg5.

在一些实施例中，终端处于空闲态，则终端通过针对空闲态的RRC建立请求(RRC Setup Request)消息或者RRC连接建立完成(RRCSetup Complete)消息，发送第二信息。In some embodiments, the terminal is in an idle state, and the terminal sends the second information via an RRC setup request (RRC Setup Request) message or an RRC connection setup completion (RRC Setup Complete) message for the idle state.

在一些实施例中，终端处于非激活态(inactive)，则终端可通过针对非激活态的针对非激活态的RRC恢复请求(RRC Resume Request)消息或者RRC连接恢复完成(RRC Resume Complete)消息，发送第二信息。In some embodiments, if the terminal is in an inactive state, the terminal may send the second information via an RRC resume request (RRC Resume Request) message for the inactive state or an RRC connection resume complete (RRC Resume Complete) message for the inactive state.

此处的RRC建立请求消息和RRC恢复请求消息都可为前述消息三。The RRC establishment request message and the RRC recovery request message here can both be the aforementioned message three.

此处的RRC连接建立完成消息和RRC连接恢复完成消息都可为前述消息五。The RRC connection establishment completion message and the RRC connection recovery completion message here can both be the aforementioned message five.

S5104:发送第一信息。S5104: Send the first message.

在一些实施例中，第一信息和第二信息可在同一条消息中发送，也可以是在不同条消息中发送。In some embodiments, the first information and the second information may be sent in the same message or in different messages.

若第一信息和第二信息在同一条消息中发送，则第一信息和第二信息可以通过前述消息三或消息五发送给第一基站。示例性地，第一信息的数据量小于指定阈值时，可以采用将第一信息和第二信息使用同一条消息发送给第一基站。If the first information and the second information are sent in the same message, the first information and the second information can be sent to the first base station via the aforementioned message 3 or message 5. Exemplarily, when the data volume of the first information is less than a specified threshold, the first information and the second information can be sent to the first base station using the same message.

若第一信息和第二信息在不同条消息中发送，则终端可以在进入到连接态的RRC消息或MAC层消息或UCI中发送第一信息。If the first information and the second information are sent in different messages, the terminal may send the first information in an RRC message or a MAC layer message or UCI when entering a connected state.

在一些实施例中，响应于终端退出非连接态之后进入到连接态发送第一信息，则终端会请求进入到连接态。In some embodiments, in response to the terminal exiting the non-connected state and then entering the connected state to send the first information, the terminal will request to enter the connected state.

在请求进入到连接态时，第二信息还可包括如下信息至少其中之一：When requesting to enter the connected state, the second information may further include at least one of the following information:

第一原因，指示终端请求第二信息发送；A first reason, indicating that the terminal requests the second information to be sent;

第二原因，指示终端请求建立仅RRC信令连接；The second reason indicates that the terminal requests to establish an RRC signaling connection only;

第三原因，指示终端移动发起数据；The third reason indicates that the terminal moves and initiates data;

任务标识，指示获取第一设备的第二信息的收集任务；A task identifier, indicating a collection task for obtaining second information of the first device;

第二标识，指示第一设备。The second identifier indicates the first device.

该第二信息可携带在消息三(Msg3)。The second information may be carried in message three (Msg3).

在一些实施例中，第一原因可为相当于显性指示有第二信息发送。例如，第一原因可包括原因码，该原因码对应的比特的值为“1”则可认为是终端请求第二信息的发送。第二信息不携带该原因码，或者该原因码对应的比特的值为“0”，则可认为终端未请求第二信息的发送。 In some embodiments, the first reason may be equivalent to an explicit indication that the second information is sent. For example, the first reason may include a reason code, and if the value of the bit corresponding to the reason code is "1", it can be considered that the terminal requests the sending of the second information. If the second information does not carry the reason code, or the value of the bit corresponding to the reason code is "0", it can be considered that the terminal does not request the sending of the second information.

在一些实施例中，终端可默认由于第二信息触发了预设事件，则发送第二原因。第二原因指示终端请求建立仅RRC信令连接。In some embodiments, the terminal may default to sending the second cause because the second information triggers a preset event. The second cause indicates that the terminal requests to establish an RRC signaling-only connection.

在一些实施例中，第二信息、终端自身的其他业务数据或者终端接收到系统消息更新通知等原因导致终端想要进入到连接态，则通过第一信息发送第三原因。第三原因可用于请求建立RRC连接，该RRC连接可包括但不限于常规的RRC连接。In some embodiments, if the terminal wants to enter the connected state due to the second information, other service data of the terminal itself, or the terminal receiving a system message update notification, the third reason is sent through the first information. The third reason can be used to request to establish an RRC connection, which may include but is not limited to a conventional RRC connection.

在一些实施例中，该第一标识可包括一个或多个部分。示例性地，该第一标识可至少包括：第一部分和第二部分。In some embodiments, the first identifier may include one or more parts. For example, the first identifier may include at least: a first part and a second part.

小区标识；Cell ID;

基站标识；Base station identification;

小区组标识；Cell group identifier;

跟踪区标识。Tracking area identifier.

第二部分，可为网络设备分配的读取器的序列码(Sequence Number，SN)。The second part is the serial number (Sequence Number, SN) of the reader that can be assigned to the network device.

在一些实施例中，第一标识还可包括第三部分。第三部分可根据终端的用户同意或者签约的低于第一设备的类型和/或业务类型来确定。In some embodiments, the first identifier may further include a third part. The third part may be determined according to a type and/or service type lower than the first device type agreed or signed by the user of the terminal.

示例性地，第三部分可包括但不限于以下至少之一：Exemplarily, the third part may include, but is not limited to, at least one of the following:

第一设备可包括设备类型码；The first device may include a device type code;

终端可支持的为第一设备转发的业务码等。The terminal can support the service code forwarded by the first device, etc.

任务标识指示第一任务，如此，第一信息包含任务标识，网络设备可以根据该任务标识知晓到本次进入到连接态的原因是上报第一设备的第一信息发送。The task identifier indicates the first task. Thus, the first information includes the task identifier. The network device can know from the task identifier that the reason for entering the connection state this time is to report the first information sent by the first device.

第二标识可为第一设备的第二标识。第一设备的标识可包括一个或多个部分。示例性地，第一设备的第二标识可包括任务标识、分发第一任务的小区标识和/或分发第一任务的基站标识。The second identifier may be the second identifier of the first device. The identifier of the first device may include one or more parts. Exemplarily, the second identifier of the first device may include a task identifier, a cell identifier for distributing the first task, and/or a base station identifier for distributing the first task.

第一基站接收到该第二信息之后，可通过消息四和消息五的交互，与终端建立RRC连接。此处建立的RRC连接可包括但不限于：常规RRC连接或仅RRC信令连接(RRC Signaling only connection)。After receiving the second information, the first base station may establish an RRC connection with the terminal through the interaction of message 4 and message 5. The RRC connection established here may include but is not limited to: a regular RRC connection or an RRC signaling only connection.

RRC连接建立包括：建立终端和第一基站之间的信令承载和/或数据承载。The RRC connection establishment includes: establishing a signaling bearer and/or a data bearer between the terminal and the first base station.

信令承载的建立可包括但不限于：为终端分配信令无线承载(signaling Radio Bearer，SRB)。该SRB可包括SRB1和/或SRB2。该SRB可用于控制面的信令传输。SRB还可包括SRB0。该SRB0无需建立，可以用于公共控制信道(Common Control Channel，CCCH)的信令传输。CCCH传输的信令可包括但不限于RRC连接请求消息、RRC连接拒绝消息、RRC连接建立消息、RRC连接重建立消息和/或RRC连接重建立拒绝消息。The establishment of a signaling bearer may include, but is not limited to, allocating a signaling radio bearer (SRB) to the terminal. The SRB may include SRB1 and/or SRB2. The SRB may be used for signaling transmission on the control plane. SRB may also include SRB0. The SRB0 does not need to be established and can be used for signaling transmission on a common control channel (CCCH). The signaling transmitted by the CCCH may include, but is not limited to, an RRC connection request message, an RRC connection rejection message, an RRC connection establishment message, an RRC connection re-establishment message, and/or an RRC connection re-establishment rejection message.

SRB1可用于传输各种RRC消息。该RRC消息可为除去CCCH传输RRC信令以外的所有RRC消息。SRB1 can be used to transmit various RRC messages. The RRC messages can be all RRC messages except CCCH transmission RRC signaling.

SRB2可用于重配消息的建立。SRB2的优先级低于SRB1的优先级。例如，SRB2可用于传输非接入层(Non Access Stratum,NAS)消息。SRB2 can be used to establish reconfiguration messages. The priority of SRB2 is lower than that of SRB1. For example, SRB2 can be used to transmit Non Access Stratum (NAS) messages.

示例性地，SRB0可用于各种CCCH传输的信令。Exemplarily, SRB0 may be used for signaling of various CCCH transmissions.

数据承载的建立可包括但不限于：为终端分配(Data Radio Bearer，DRB)。该DRB可用于数据面的数据传输。The establishment of a data bearer may include but is not limited to: allocating a Data Radio Bearer (DRB) to a terminal. The DRB can be used for data transmission on the data plane.

在建立RRC连接的过程中，为终端配置SRB1、SRB2和/或DRB。During the process of establishing the RRC connection, SRB1, SRB2 and/or DRB are configured for the terminal.

在一些实施例中，基于第一基站为RRC连接建立过程中，为RRC连接分配的无线承载发送第二信息。In some embodiments, the second information is sent based on a radio bearer allocated for the RRC connection during the RRC connection establishment process by the first base station.

该无线承载包括但不限于信令无线承载(signaling Radio Bearer，SRB)和/或数据无线承载(Data Radio Bearer，DRB)。The radio bearer includes but is not limited to a signaling radio bearer (SRB) and/or a data radio bearer (DRB).

在一些实施例中，RRC连接可包括常规RRC连接和仅RRC信令连接(RRC Signaling only connection)。这种仅RRC信令连接的建立，仅涉及SRB1的建立以及AS安全激活，不建立SRB2和DRB。即仅RRC信令连接是一种简化的RRC连接。In some embodiments, the RRC connection may include a conventional RRC connection and an RRC signaling only connection. The establishment of such an RRC signaling only connection only involves the establishment of SRB1 and AS security activation, and does not establish SRB2 and DRB. That is, the RRC signaling only connection is a simplified RRC connection.

在一些实施例中，若终端和第一基站之间建立的是常规RRC连接，则可该RRC连接不仅需要建立SRB，还可建立DRB。故在这种情况下，终端可被配置有SRB1、SRB2和/或DRB。In some embodiments, if a conventional RRC connection is established between the terminal and the first base station, the RRC connection may not only need to establish an SRB, but also a DRB. Therefore, in this case, the terminal may be configured with SRB1, SRB2 and/or DRB.

在一些实施例中，终端内缓存的第二信息导致预设事件被触发，则可以请求建立仅RRC信令连接的建立。此时，第二信息可包括但不限于以下至少之一：In some embodiments, if the second information cached in the terminal causes a preset event to be triggered, a request may be made to establish an RRC signaling connection only. At this time, the second information may include but is not limited to at least one of the following:

第一原因，指示终端请求第二信息发送； A first reason, indicating that the terminal requests the second information to be sent;

在另一些实施例中，终端有自身业务和/或系统消息更新导致的预设事件被触发，则可以请求建立常规RRC连接，则此时第二信息可包括但不限于以下至少之一：In other embodiments, if a preset event caused by the terminal's own service and/or system message update is triggered, a request may be made to establish a regular RRC connection. At this time, the second information may include but is not limited to at least one of the following:

第四原因，指示请求获取更新后的系统消息；The fourth reason indicates a request to obtain updated system information;

第五原因，指示响应网络设备的寻呼消息。The fifth reason indicates a paging message of a response network device.

当然以上，仅仅是对根据第一信息的信息内容，确定建立的RRC连接类型的举例说明，具体实现时不局限于该举例。Of course, the above is merely an example of determining the type of RRC connection to be established according to the information content of the first information, and the specific implementation is not limited to this example.

在一些实施例中，终端与接入网设备之间建立的是仅RRC信令连接，则终端可被配置有SRB1.In some embodiments, only an RRC signaling connection is established between the terminal and the access network device, and the terminal may be configured with SRB1.

在一些实施例中，终端与接入网设备之间建立的是常规RRC连接，则终端被配置有SRB1的同时，还可被配置有SRB2以及DRB中的至少一个。In some embodiments, a conventional RRC connection is established between the terminal and the access network device. In this case, the terminal is configured with SRB1 and may also be configured with at least one of SRB2 and DRB.

在一些实施例中，基于RRC连接发送的第二信息携带有第一设备添加的任务标识；或者，基于RRC连接发送的第二信息携带有终端添加的任务标识。In some embodiments, the second information sent based on the RRC connection carries a task identifier added by the first device; or, the second information sent based on the RRC connection carries a task identifier added by the terminal.

在建立RRC连接之后，终端通过仅RRC信令连接的SRB1向第一基站发送第一信息；或者，终端通过常规的RRC连接的SRB1、SRB2和/或DRB发送第一信息。After establishing the RRC connection, the terminal sends the first information to the first base station through SRB1 connected only by RRC signaling; or, the terminal sends the first information through SRB1, SRB2 and/or DRB of a regular RRC connection.

值得注意的是：图5所示的各个步骤没有固定的先后顺序，也并非所有的步骤都是必选步骤。It is worth noting that: the steps shown in FIG. 5 have no fixed order, and not all steps are mandatory.

在一些实施例中，终端可以顺序执行S5101、S5102、S5103以及S5104。In some embodiments, the terminal may execute S5101, S5102, S5103 and S5104 sequentially.

在另一些实施例中，终端可以单独执行S5103，即S5101、S5102以及S5103并非必选步骤。例如，终端可向第一基站发送第二信息，告知终端自身有被配置第一任务。终端有被配置第一任务但是尚未到执行第一任务的时间段或者第一任务的执行触发条件尚不满足，则可能就没有执行步骤S5101、S5102以及S5104。In other embodiments, the terminal may execute S5103 alone, that is, S5101, S5102, and S5103 are not mandatory steps. For example, the terminal may send a second message to the first base station to inform the terminal that it has been configured with the first task. If the terminal has been configured with the first task but the time period for executing the first task has not yet arrived or the execution triggering condition of the first task has not yet been met, steps S5101, S5102, and S5104 may not be executed.

在还有一些实施例中，终端可执行S5101、S5102以及S5103。即S5104是可选步骤，例如，终端缓存了第一信息，但是尚未达到上报第一信息的预设事件，则终端无须执行S5104。In some other embodiments, the terminal may execute S5101, S5102, and S5103. That is, S5104 is an optional step. For example, if the terminal caches the first information but the preset event for reporting the first information has not yet been reached, the terminal does not need to execute S5104.

为了快速部署无源物联网，且能够低成本部署，提出了基终端(也即UE)为锚点的无源物联网数据收集方法。UE作为读取器(reader)，不一定需要实时得收集数据上报，可以缓存在UE侧，等UE进入连接态后统一执行数据的上报和路由转发，UE不需要因为一个小包数据收集始终保持RRC连接态，这样可以达到UE省电的目的。所以UE在RRC_IDLE/INACTIVE状态或者时RRC_CONNECTED状态都可以作为UE reader，UE是移动的，如何在UE reader移动过程支持ambient IoT业务连续性是个需要解决的问题。In order to quickly deploy passive IoT and enable low-cost deployment, a passive IoT data collection method with the base terminal (UE) as the anchor point is proposed. As a reader, UE does not necessarily need to collect data for reporting in real time. It can be cached on the UE side. After the UE enters the connected state, data reporting and routing forwarding are uniformly executed. The UE does not need to maintain the RRC connection state all the time because of a small packet of data collection, which can achieve the purpose of UE power saving. Therefore, the UE can be used as a UE reader in the RRC_IDLE/INACTIVE state or the RRC_CONNECTED state. The UE is mobile. How to support the continuity of ambient IoT services during the movement of the UE reader is a problem that needs to be solved.

参考图7A所示，方案1：RRC_IDLE/INACTIVE UE reader的业务连续性——任务配置信息不重定向(relocation)。Referring to Figure 7A, Solution 1: Service continuity of RRC_IDLE/INACTIVE UE reader - task configuration information is not redirected (relocation).

当RRC_IDLE/INACTIVE UE reader从下发任务的基站执行小区重选到另一个基站。When the RRC_IDLE/INACTIVE UE reader performs cell reselection to another base station from the base station that issued the task.

当RRC_IDLE/INACTIVE UE作为reader收集，和/或存储的数据大于一定门限，例如m字节(byte)，或者当RRC_IDLE/INACTIVE UE作为reader收集的任务已经完成，则RRC_IDLE/INACTIVE UE reader初始化RRC连接建立过程。如果当前服务基站不是获取任务配置信息的基站，则UE指示目标基站关于下发任务配置信息基站的标识ID，和/或任务id，和/或UE reader id，例如Msg5消息中。When the data collected and/or stored by the RRC_IDLE/INACTIVE UE as a reader is greater than a certain threshold, such as m bytes, or when the task collected by the RRC_IDLE/INACTIVE UE as a reader has been completed, the RRC_IDLE/INACTIVE UE reader initializes the RRC connection establishment process. If the current serving base station is not the base station for obtaining the task configuration information, the UE indicates the target base station about the identification ID of the base station that sends the task configuration information, and/or the task id, and/or the UE reader id, such as in the Msg5 message.

目标基站收到UE的指示信息，寻址源基站，并把如下信息通知给目标基站，例如任务id，和/或UE reader id。可选，还携带一个指示信息，指示源基站转发任务配置信息给。其中UE reader id为分配任务时，或者配置UE为reader时分配的reader标识，唯一标识一个UE为reader，该UE reader标识，包含两部分信息，一部分为标识gNB的信息，另一部分为标识UE的信息。任务id为给UE分配置IoT任务时分配的任务标识。The target base station receives the indication information from the UE, addresses the source base station, and notifies the target base station of the following information, such as the task id and/or the UE reader id. Optionally, it also carries an indication information to instruct the source base station to forward the task configuration information to. The UE reader id is the reader identifier assigned when assigning a task or configuring the UE as a reader, which uniquely identifies a UE as a reader. The UE reader identifier contains two parts of information, one for identifying the gNB and the other for identifying the UE. The task id is the task identifier assigned when the IoT task is assigned to the UE.

目标基站决定转发任务配置信息，或者源基站判决转发任务配置信息。这里假定不转发任务配置信息。The target base station decides to forward the task configuration information, or the source base station decides to forward the task configuration information. It is assumed here that the task configuration information is not forwarded.

源基站接收到目标基站的转发任务配置信息的请求信息后，发送响应消息，响应消息，携带GTP tunnel id或者XnAP标识(id)，GTP隧道标识(tunnel id)或者XnAP id关联一个任务id。After receiving the request information of the forwarding task configuration information from the target base station, the source base station sends a response message, which carries the GTP tunnel id or XnAP identifier (id). The GTP tunnel identifier (tunnel id) or XnAP id is associated with a task id.

目标基站将UE上报的收集数据通过上述隧道转发给源基站，源基站根据任务id，识别出收集数据在接入网侧的路由和转发信息，即GTP隧道(tunnel)，或者XnAP连接信息，或者NGAP连接信息，或者IP地址等。The target base station forwards the collected data reported by the UE to the source base station through the above tunnel. The source base station identifies the routing and forwarding information of the collected data on the access network side according to the task id, that is, the GTP tunnel, or the XnAP connection information, or the NGAP connection Information, or IP address, etc.

如图7B所示，方案2：RRC_IDLE/INACTIVE UE reader的业务连续性——任务配置信息的重定向(relocation)。As shown in Figure 7B, Solution 2: Business continuity of RRC_IDLE/INACTIVE UE reader - redirection (relocation) of task configuration information.

当非激活态(RRC_IDLE/INACTIVE)UE reader从下发任务的基站执行小区重选到另一个基站，当RRC_IDLE/INACTIVE UE作为reader收集，和/或存储的数据大于一定门限，例如m byte，或者当RRC_IDLE/INACTIVE UE作为reader收集的任务已经完成，则RRC_IDLE/INACTIVE UE reader初始化RRC连接建立过程。如果当前服务基站不是获取任务配置信息的基站，则UE指示目标基站关于下发任务配置信息基站的标识，和/或任务id，和/或UE reader的标识id，例如Msg5消息中。When an inactive (RRC_IDLE/INACTIVE) UE reader performs cell reselection from the base station that issues the task to another base station, when the data collected and/or stored by the RRC_IDLE/INACTIVE UE as a reader is greater than a certain threshold, such as m byte, or when the task collected by the RRC_IDLE/INACTIVE UE as a reader has been completed, the RRC_IDLE/INACTIVE UE reader initializes the RRC connection establishment process. If the current serving base station is not the base station that obtains the task configuration information, the UE indicates the target base station about the identifier of the base station that issues the task configuration information, and/or the task id, and/or the identifier id of the UE reader, such as in the Msg5 message.

目标基站收到UE的指示信息，寻址源基站，并把如下信息通知给目标基站，例如任务ID，和/或UE reader ID。可选，还携带一个指示信息，指示源基站转发任务配置信息给。其中UE reader ID为分配任务时，或者配置UE为reader时分配的reader标识，唯一标识一个UE为reader，该UE reader标识，包含两部分信息，一部分为标识gNB的信息，另一部分为标识UE的信息。任务ID为给UE分配置IoT任务时分配的任务标识。The target base station receives the indication information from the UE, addresses the source base station, and notifies the target base station of the following information, such as the task ID and/or the UE reader ID. Optionally, it also carries an indication information to instruct the source base station to forward the task configuration information to. The UE reader ID is the reader identifier assigned when assigning a task or configuring the UE as a reader, which uniquely identifies a UE as a reader. The UE reader identifier contains two parts of information, one part is the information identifying the gNB, and the other part is the information identifying the UE. The task ID is the task identifier assigned when the UE is assigned an IoT task.

目标基站决定转发任务配置信息，或者源基站判决转发任务配置信息。这里假定转发任务配置信息。The target base station determines the forwarding task configuration information, or the source base station determines the forwarding task configuration information. Here, it is assumed that the forwarding task configuration information.

ambient IoT任务的配置信息可以包含，但不限于以下至少之一：The configuration information of ambient IoT tasks can include, but is not limited to, at least one of the following:

ambient IoT任务下发对应的小区信息，例如小区ID信息，频率信息或者频谱范围信息，信道信息，子信道配置信息等等。The ambient IoT task sends the corresponding cell information, such as cell ID information, frequency information or spectrum range information, channel information, sub-channel configuration information, etc.

源基站接收到目标基站的转发任务配置信息的请求信息后，发送响应消息，响应消息，携带任务相关的配置信息。After receiving the request information of the forwarding task configuration information from the target base station, the source base station sends a response message, and the response message carries the configuration information related to the task.

目标基站接收到任务配置信息之后，目标基站根据任务ID，识别出收集数据在接入网侧的路由和转发信息，即GTP隧道(tunnel)，或者XnAP连接信息，或者NGAP连接信息，或者IP地址等，将UE上报的收集数据进行路由转发给上游节点。After the target base station receives the task configuration information, it identifies the routing and forwarding information of the collected data on the access network side according to the task ID, i.e., the GTP tunnel, or XnAP connection information, or NGAP connection information, or IP address, etc., and routes and forwards the collected data reported by the UE to the upstream node.

方案3：RRC_CONNECTED UE reader的业务连续性：Solution 3: Service continuity of RRC_CONNECTED UE reader:

选项1:RRC_CONNECTED UE reader在接收到切换命令之前，源基站通知目标基站关于任务的配置信息，例如在HANDOVER REQUEST message。目标基站在接收到UE上报的收集数据后，根据任务配置信息进行路由转发，即GTP tunnel，或者XnAP连接信息，或者NGAP连接信息，或者IP地址等，将UE上报的收集数据进行路由转发给上游节点。Option 1: RRC_CONNECTED UE reader Before receiving the handover command, the source base station notifies the target base station of the configuration information of the task, such as in the HANDOVER REQUEST message. After receiving the collected data reported by the UE, the target base station performs routing forwarding according to the task configuration information, i.e., GTP tunnel, or XnAP connection information, or NGAP connection information, or IP address, etc., and routes and forwards the collected data reported by the UE to the upstream node.

选项2:RC_CONNECTED UE reader在接收到切换命令之前，源基站决定不转发任务配置信息，源基站通知目标基站关于从目标基站路由转发UE上报数据的隧道标识，即GTP tunnel ID或者XnAP连接标识，例如在HANDOVER REQUEST message。目标基站在接收到UE上报的收集数据后，根据据源基站给出的路由配置，将UE上报的收集数据转发给源基站。Option 2: RC_CONNECTED UE reader Before receiving the handover command, the source base station decides not to forward the task configuration information. The source base station notifies the target base station about the tunnel identifier, i.e., GTP tunnel ID or XnAP connection identifier, for example, in the HANDOVER REQUEST message for routing forwarding UE reported data from the target base station. After receiving the collected data reported by the UE, the target base station forwards the collected data reported by the UE to the source base station according to the routing configuration given by the source base station.
