最新NB-IoT网络架构、数据传输优化方案

最新NB-IoT网络架构、数据传输优化方案

NB-IoT网络架构、数据传输优化方案NB-IoT的引入,给LTE/EPC网络带来了很大的改进要求。

传统的LTE网络的设计主要是为了适应宽带移动互联网的需求,即为用户提供高带宽、高响应速度的上网体验。

但是,NB-IoT却具有显著的区别:终端数量众多、终端节能要求高(现有LTE信令流程可能导致终端耗能高)、以小包收发为主(会导致网络信令开销远远大于数据载荷传输本身大小)、可能有非格式化的Non-IP数据(无法直接传输)等。

为了适应NB-IoT终端的接入需求,3GPP对网络整体架构和流程进行了增强,提出了一些解决方案,这主要包括如何适配小包业务的传输、无线侧怎么适配、怎么解决Non-IP数据的传输、怎么传输SMS短信业务等。

1 NB-IoT总体网络架构NB-IoT的端到端系统架构如下图所示。

»NB-IoT终端:通过空口连接到基站。

»eNodeB:主要承担空口接入处理,小区管理等相关功能,并通过S1-lite接口与IoT核心网进行连接,将非接入层数据转发给高层网元处理。

这里需要注意,NB-IoT可以独立组网,也可以与EUTRAN融合组网(在讲双工方式的时候谈到过,NB仅能支持FDD哦,所以这里必定跟FDD融合组网)»IoT核心网:承担与终端非接入层交互的功能,并将IoT业务相关数据转发到IoT平台进行处理。

同理,这里可以NB独立组网,也可以与LTE共用核心网。

需要注意的是,这里笼统的写成IoT核心网那是偷懒且毫不负责任的写法,下文将就此进行详细介绍,这里涉及到较多的技术细节。

»IoT平台:汇聚从各种接入网得到的IoT数据,并根据不同类型转发至相应的业务应用器进行处理。

» 应用服务器:是IoT数据的最终汇聚点,根据客户的需求进行数据处理等操作。

2 NB-IoT中UP和CP优化传输方案大PK为了适配NB-IoT的数据传输特性,协议上引入了CP和UP两种优化传输方案,即control plane CIoT EPS optimization和user plane CIoT EPS optimization。

4 NB-IoT窄带蜂窝物联网概述 ISSUE1.00

●IoT是未来5年全球发展的趋势之一,将带来巨大的商业价值。

2025 市场空间11.1 万亿美元(Mc Kinsey Global Research 2015 )。

●基于运营商网络的蜂窝物联网也将在未来5年获得快速的增长,符合GSMA的预测,未来5年,蜂窝物联网将增长7倍,到2020年,将有约3billion的联接承载在运营商的网络,工业(Smart Agriculture、Smart Meter),个人应用(Smart Band、Smart Watch),智能家庭(Smart Band、Smart Watch),公共事业(Asset Tracking、SmartParking )等多个方面。

●基于这些巨大的联接,将给运营商带来巨大的商业价值,包括联接的价值,数据的价值和利益分享的价值。

●覆盖了90%人口,70%地理覆盖的蜂窝网是运营商的最大优势,可以帮助蜂窝物联网迅速普及,形成全球化的效应,这是其他的任何技术所不能比拟的。

所以基于这种网络去部署NB-IoT也将形成绝对的优势,帮助运营商进入蜂窝物联网的市场;我们也注意到,当前运营商的蜂窝物联网份额还是非常小,这是不合理的,背后的原因包括技术和驱动。

基于NB-IoT、eMTC等技术以及产业共同的努力,相信2020年蜂窝物联网将达到30%,3billion●NB-IoT: 最大化重用现有网络资产。

最具成本竞争力的LPWA解决方案。

●NB-IoT支持三种部署场景☐Standalone:通常是Refarming GSM的频谱或者使用空闲零散的频谱资源部署NB- IOT。

☐Guard band:在LTE的保护带中部署NB-IOT。

☐In-band:在LTE的RB资源上部署NB-IOT,相应LTE可利用的RB资源会减少。

●100K 连接/ 扇区,与4G相比提升100x倍。

●深覆盖,20dB+ 增益,与2G相比多穿透一堵墙。

●2G/3G/4G的芯片是为手机设计的,这意味着芯片处理能力要求更高,包括支持宽带,大数率,MIMO等,而NB-IOT的芯片是专门为物联网设备设计的,只针对窄带、低速率、并针对物联网需求只支持单天线、半双工方式,另外简化了信令处理。

(start from 1) (ex: the config of Modbus Device Number 0 is the 1st Modbus device) ⚫I/O Number: the number of this Modbus device's I/O. (start from 1)NOTICE: If enabled “Read DO” or “Read AO”, in addition to DO/AO’s mapping table, also need to set these DO/AO to DI/AI’s mapping table.Example:If the 1st Modbus Device (the config of Modbus Device Number 0 in “Modbus Device”page) have 2 AI and 5 AO, in addition to the “1-1” and “1-2” for AI, also need to set “1-3”, “1-4”, “1-5”, “1-6”, and “1-7”in AI table (for enable Read AO). In this case, the GRP-540M-NB will send DEVINFO, AO, AI (with 7 values--2 AI and 5 AO), and GPS messages.4.Example4.1Data Collection and Remote Control (NB-DA Server)This example shows data collection and remote control application via NB-DA Server.There are PM-3112 and SAR-713 in this system.(1) Please connect your device (PM-3112 and SAR-713) to serial port of GRP-540M-NB.Baud Rate of these devices is 115200 bps, data format is 8N1 (Data bits, Parity, Stop bits).(Must attention that Baud Rate of all Modbus devices must set same value when using RS-485)(2) If you never use NB-DA Server, please refer to NB-DA Server's website.(3) Add devices in “Modbus Device” tab.In this case, we want to use two AO values of SAR-713, but their Modbus address is not continuing. We split SAR-713’s setting to two Modbus settings like below:In the 1st setting, we set to read 1 AO on AO address 9, and the 2nd setting read 1 AO on address 11. Besides, the SAR-713’s AO is the values we want, so “Read AO” is needed too.The PM-3112’s setting is below, it has 4 AI need to be read:(4) Set I/O mapping table:The Session ID is used to let NB-DA Server identifies this GRP device, so must not set the same ID if using more than one device.Because SAR-713 enable “Read AO”, the AO of SAR-713 also need to be entered into AI table.There is no AI need to be read from SAR-713, so the AO become “1-1” and “2-1” to AI table and AI of PM-3112 are “3-1”, “3-2”, “3-3”, “3-4”.(5) Set APN of your SIM card, the IP and port for NB-DA Server, and Enable the function.Press “Modify”(6) Setting NB-DA Server:(a) The server port is set “5394” in GRP-540M-NB, so server must use “5394” to receive data.(b) Click “Add Server” after all settings are ready.(c) Choose the server and click “Start Server”.(d) After server start, if received data from GRP-540M-NB, we can see the Session live statuson the Sessions block.(7) After receiving data, if the server enables MQTT or Database, user can get data from access database or subscribe MQTT topic to receive data. The server also creates Modbus Server by default, user can connect Modbus Server with local IP and the port setting on server, then use Modbus TCP command to get data.(8) If user wants to control remote DO/AO, user can change the values on the Modbus Server or publish DO/AO MQTT message to the topic which NB-DA Server subscribed.⚫[Server Side] The MQTT control message for DO/AO like below:1 byte for every DO, hex format, and data length must be 32. (set 00 for empty DO)2 bytes for every AO, hex format, and data length must be 32. (set 0000 for empty AO)⚫[Server Side] The DEVINFO/DI/AI/GPS/ACK data like below:DEVINFO data include RSRP, ECL, SNR, and Battery level.1 byte for every DI, hex format, and data length must be 32. (empty DI will be 00)2 bytes for every AI, hex format, and data length must be 32. (empty AI will be 0000)GPS data is “$GPRMC” message of NMEA 0183 protocol.4.2Data Collection and Remote Control (MQTT Broker)This example shows data collection and remote control application via MQTT broker.There are PM-3112 and SAR-713 in this system.(1) Please connect your device (PM-3112 and SAR-713) to serial port of GRP-540M-NB.Baud Rate of these devices is 115200 bps, data format is 8N1 (Data bits, Parity, Stop bits).(Must attention that Baud Rate of all Modbus devices must set same value when using RS-485)(2) If you never use NB-DA Server, please refer to NB-DA Server's website.(3) Add devices in “Modbus Device” tab. (same as Example 4.1)(4) Set I/O mapping table. (same as Example 4.1)(5) Set APN of your SIM card, the IP/Domain and port for MQTT Broker. According to user’sapplication, set the topic for subscribe and publish. Enable the function and press “Modify”.(If using CHT IoT Platform, also need to set User Name, Password, Device ID, and Sensor ID, then enable “Use CHT platform”)When using normal MQTT Broker, the message will be:⚫[GRP-540-NB Side] The MQTT control message for DO/AO like below:1 byte for every DO, hex format, and max data length is 32.2 bytes for every AO, hex format, and max data length is 32.Must include “Session ID/Type” in the end of topic like “ER/0/0/DO”(Please check the numbers of DO/AO, don’t send more or less than real I/O numbers)⚫[GRP-540-NB Side] The DEVINFO/DI/AI/GPS/ACK data like below:DEVINFO data include RSRP, ECL, SNR, and Battery level.1 byte for every DI, hex format, and max data length is 32.2 bytes for every AI, hex format, and max data length is 32.GPS data is “$GPRMC” message of NMEA 0183 protocol.ACK data is published by GRP when it received DO/AO control message.

NB-IoT详细解读

NB-IoT详细解读..一、为什么NB—IoT会出现?据预测,2016年全球将会使用64亿个物联网设备每天将有550万个设备连网, 而“万物互联”实现的基础之一在于数据的传输, 不同的物联网业务对数据传输能力和实时性都有着不同要求。

根据传输速率的不同, 可将物联网业务进行高、中、低速的区分..高速率业务:主要使用3G、4G技术, 例如车载物联网设备和监控摄像头.对应的业务特点要求实时的数据传输..中等速率业务:主要使用GPRS技术,例如居民小区或超市的储物柜, 使用频率高但并非实时使用,对网络传输速度的要求远不及高速率业务..低速率业务: 业界将低速率业务市场归纳为LPWAN(work)市场, 即低功耗广域网。

目前还没有对应的蜂窝技术,多数情况下通过GPRS技术勉力支撑, 从而带来了成本高、影响低速率业务普及度低的问题.也就是说目前低速率业务市场急需开拓, 而低速率业务市场其实是最大的市场, 如建筑中的灭火器、科学研究中使用的各种监测器, 此类设备在生活中出现的频次很低,但汇集起来总数却很可观, 这些数据的收集用于各类用途,比如改善城市设备的配置等等.而NB-IoT就是一种新的窄带蜂窝通信LPWAN(低功耗广域网)技术, 可以帮助我们解决这个问题.二、NB-IoT的优势是什么.作为一项应用于低速率业务中的技术, NB—IoT的优势不难想象.强链接: 在同一基站的情况下, NB—IoT可以比现有无线技术提供50-100倍的接入数。

一个扇区能够支持10万个连接, 支持低延时敏感度、超低的设备成本、低设备功耗和优化的网络架构.举例来说, 受限于带宽,运营商给家庭中每个路由器仅开放8—16个接入口, 而一个家庭中往往有多部手机、笔记本、平板电脑, 未来要想实现全屋智能、上百种传感设备需要联网就成了一个棘手的难题。

而NB-IoT足以轻松满足未来智慧家庭中大量设备联网需求.高覆盖:NB-IoT室内覆盖能力强, 比LTE提升20dB增益, 相当于提升了100倍覆盖区域能力.不仅可以满足农村这样的广覆盖需求, 对于厂区、地下车库、井盖这类对深度覆盖有要求的应用同样适用。

三、参数说明CELL ID 基站小区标识CELL ID是网络中小区的编号,与MCC、MNC及LAC号组合成一个小区全球识别码,用来在全球范围内唯一识别某一小区。

EARFCN 中心频点若一个区域的基站中心频点都相同,表示是同频部署。

若一个区域的基站中心频点交叉分布,表示是异频部署。

PCI 物理小区标识PCI是用于区分不同小区的无线信号,确保在小区覆盖范围内不会有相同的PCI。

SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)SINR是指接收到的有用信号的强度与接收到的干扰信号(噪声和干扰)的强度的比值,反映当前信道的链路质量。
