June 16, 2016, this is the cellular networking industry, the most important day, this day in Busan, South Korea, held the 3GPP ran plenary session of the 72nd meeting successfully concluded. Nb-iot (narrow Band Internet of things, narrowband cellular networking) as an important topic of 3GPP R13, its corresponding 3GPP protocol related content obtained ran plenary approval, The Nb-iot standard core agreement, which is widely supported by the wireless industry, has been officially announced and has been fully completed after more than 2 years of research. The global operator finally has the standardization of the Internet of things proprietary agreements, based on the standard products and solutions will be able to provide a good service to the vast number of industries in the Internet of things. The successful completion of the work of standardization also marks the upcoming Nb-iot into the commercial stage of scale.

Nb-iot Standard origin

The Internet of things can be applied in all aspects of production and life, and its business has a different demand for network transmission rates. High-speed business mainly uses 3G, 4G technology, such as surveillance cameras, medium-rate business mainly uses GPRS technology, such as POS machine. Low-rate business is currently not very good cellular technology to meet, in many cases can only use the GPRS technology to support. With the development of the Internet of Things, the low-speed business has gradually become the main market development direction of cellular networking in the future, the industry has summed up the market as Lpwan (Low power Wide area Network) market, that is, Low-power Wan. The GPRS technology can not meet the demand of Lpwan market because of its high terminal power consumption and insufficient coverage ability. Therefore, operators want to have a new cellular networking technology to meet Lpwan market demand.

Based on a keen insight into the trends and needs of cellular networking, at the beginning of 2013, Huawei and the industry consensus operators, equipment manufacturers, chip manufacturers to carry out extensive and in-depth needs and technical research, and quickly reached a narrow-band cellular networking industry development Consensus, Nb-iot research officially started. At that time, people for this narrow-band cellular network called Lte-m, all known as LTE for Machine to Machine, the name contains the expectation is based on LTE to produce a revolutionary new technology, the technology can not only low cost and low power consumption, but also with the LTE network to deploy.

Lte-m identified the key objectives of the narrow-band cellular networking: coverage needs to reach 99.9%, link budget is at least 20dB higher than GSM, terminal power consumption is lower, the terminal module cost is less than 5 dollars.

With this demand as the goal, Huawei, as the only Chinese equipment manufacturer, puts forward the idea of narrowband design, and theoretically demonstrates that the upstream narrow band can bring a higher capacity in the coverage restricted region, which lays a solid foundation for the subsequent development of Nb-iot, and its classic narrow-band lifting capacity formula is widely used. In addition, Huawei also pioneered the concept of uplink 3.75kHz LTE, systematically describes the design concept of 180kHz narrowband systems and the potential benefits. Including GSM, UMTS, LTE deployment, such as in the GSM refarming scene, as long as a GSM carrier 200KHZ resources, you can deploy this 180kHz narrowband system. In addition, the 180kHz narrowband system can also be deployed in the LTE protection belt, these design ideas have become the basis of the Nb-iot standard.

Nb-iot Standard making process

A technology to become a 3GPP standard, the first need to become an SI (Study Item), research and analysis after the production of TR (technical), after the 3GPP organizational review can be turned into the WI (Work item), The TS (Technical specification) is then output by each work item group. Because of the need for huge research resources to invest, so the whole process by one or several industry leading enterprises, reflected in the organizational form is generally the biggest contributor to the company as a speaker. The Nb-iot's 4 reports are Vodafone, Huawei, Ericsson and Qualcomm.

From Lte-m to Ciot

At that time, there are two main ideas in the choice of technical scheme of LTE-M: One is based on the existing GSM evolution, and the other is the new idea proposed by Huawei, which was named NB-M2M.

In May 2014, the Si "cellular System Support", supported by Vodafone, China Mobile, orange,telecom Italy, Huawei, Nokia, etc. complexity Put Internet of things "in the 3GPP Geran Workgroup Project, both of these ideas are included, Lte-m's name evolved into cellular IoT, referred to as Ciot. As the vast majority of operators are more concerned about the new scheme, so for a long time, NB-M2M became a hot topic for operators.

From NB-M2M to Nb-ciot

Along with the progress of the work, the Ciot of the standardization research in Geran got more and more operators, the manufacturer's attention, has been deserted Geran gradually again lively. Some of the operators, equipment dealers, chip manufacturers who have not participated in the Geran meeting have returned to Geran and paid attention to Ciot topics.

An important decision was made at the PCG (Project coordination Group) meeting at the end of April 2015: Ciot after SI in Geran, the WI phase to ran project and complete the relevant agreement. This shows that the Ciot subject by the global operators of widespread concern, so PCG resolution will ciot this sapling from Geran pulled to the RAN, and then grow up further.

Ran participate in many companies, in order to achieve standard progress as soon as possible, integration and collaboration is the most effective approach, which is the only way to jointly promote an industry. May 2015, Huawei and Qualcomm on the basis of consensus, jointly announced a fusion solution, that is, uplink using FDMA Multiple access approach, downlink using the OFDM multiple access approach, after the fusion of the scheme name is called Nb-ciot (narrow Band cellular IoT).

From Nb-ciot to Nb-iot

With the market gradually clear, cellular networking standards, industry, the movement is accelerating. The integration of Huawei and Qualcomm Technology Solutions has further shaken the industry. For the cellular networking this future has a huge space in the market direction, no one is willing to do the backward. After Huawei and Qualcomm announced the integration of technology solutions, more companies were involved in tracking the progress of Nb-ciot SI standards.

At the same time, other manufacturers have been driven by market demand and accelerated the pace of research and development in narrowband areas. After a period of brewing, Ericsson United several companies, in the Geran si phase of the last meeting, that is, Geran August 10, 2015 meeting, presented the Nb-lte (narrow Band LTE) concept. At the ran#69 meeting in September 2015, after intense discussion, the parties finally reached a consensus, and the integration of the Nb-ciot and nb-lte two technical programmes resulted in Nb-iot WID. The Nb-ciot evolved to Nb-iot (narrow Band IoT).

The development course of Nb-iot Standard

Nb-iot Core Agreement Freeze, September complete performance specification

As of June 16, the Nb-iot R core Agreement had been frozen in four working groups in RAN1, RAN2, RAN3 and RAN4. Performance specifications in the 3GPP RAN4 Working Group, scheduled to end in September. Performance Specification Nb-iot and EMTC at the same time, the plan is completed at the same time.

Huawei actively contributes to nb-iot standardization work

Nb-iot has received unprecedented attention from the industry. 3GPP companies have contributed a large number of proposals, starting from Geran Si, the total contribution of the company 3205 technical proposals, the adoption of a total of 447 proposals, is fruitful. Among them, Huawei contribution proposal 1008, 184 approved, accounting for all 447 of the approved proposal 41%. Huawei has contributed most of the standard proposals, ranking first in the world, demonstrating strong standards and conceptual leadership. Huawei has contributed about 98% of its adoption proposals to 4 leading European and American companies.

As a major contributor to the Nb-iot standard, Huawei has contributed a great deal at all stages:

Study Item Stage

Since the earliest nb-m2m in May 2014 in Geran Si Project, Huawei has done a lot of research work ahead of time. At the first SI meeting, Huawei submitted to support the SI nb-m2m technical concept of the discussion draft, and in the subsequent Geran meeting to quickly improve the NB-M2M technology program, a powerful impetus to Geran si progress.

Work Item Stage

Work item is launched in Ran, Huawei has served as the second speaker of the Nb-iot topic, taking on the role of the Organization, the summary of a large number of evaluations and the overall responsibility of the subject's progress under the line of the topic. As the nb-iot involves a whole new development of empty, the workload is huge, so the subject set up 4 of the speaker, in turn, Vodafone, Huawei, Ericsson, Qualcomm.

In addition to the speaker, Huawei has undertaken a lot of technical and organizational work. Especially after October 2015, Nb-ciot and Nb-lte Fusion, each meeting has nearly 200 technical proposals, to carry out a large number of technical program research and demonstration, evaluation of the performance of technical programs, comprehensive analysis of the pros and cons of the integration of the trade-offs. Both need to have a deep technical ability, but also to farsighted strategists the overall situation, and to be able to coordinate the organizations and companies in unison. Huawei is well on the job, responsible for the final collation of the output of the authoritative evaluation of the summary version, formed the r1-157741 proposal, and get RAN1 unanimously passed.

In the ensuing December 2015 to April 2016 the Nb-iot agreement was developed into a critical sprint phase. Nb-iot's 4-member Vodafone, Huawei, Ericsson and Qualcomm, after collective bargaining, decided to engage in extensive discussions to speed up the progress of Nb-iot standardization. In mid-December 2015, 4 speakers established a group of more than 40 companies, a total of more than 150 members, and established 11 discussion topics, including synchronization, random access, broadcasting, etc. Among them, Huawei undertakes the organizer of 3 issues, such as synchronization, downlink reference signal and downlink multiplexing, and 8 other topics are undertaken by 7 companies, such as Ericsson and Qualcomm. Huawei has not only submitted a lot of technical advice on its own issues, but has also been actively involved in discussions on issues organized by other companies, contributing to 3GPP progress.

Chair meetings and agreement writing

3GPP standardization Another key task is the writing of protocols. As the overall author of the LTE agreement 36.212 agreement, Huawei has completed a high quality completion of the 36.212 Nb-iot Agreement writing. In addition, Huawei also undertook the 36.300,36.302,36.331 agreement related Nb-iot writing work, has made the positive contribution for the 3GPP Nb-iot standard progress.

Usually 3GPP meetings are chaired by the Chairmen of the various working groups, and can be presided over by authoritative experts in this field in times of conflict. This was the case at the 3GPP RAN1 84BIS Conference held in Busan, South Korea, where senior standard expert Brian Nb-iot Some of the issues.

Nb-iot Standard in China

Research by many industry analysts thinks China will become the world's largest internet of things. Synchronized with the 3GPP standardization Rhythm, domestic Nb-iot related standards have been set up. In November 2015, China Communication Standardization Association CCSATC5 WG9#74 Meeting, through the "object-oriented network of cellular narrowband wireless access overall technical requirements" of the project, marking the official launch of domestic nb-iot standardization work. At the beginning of the June 2016 CCSA TC5 wg9#77 meeting, the Nb-iot series of line labels (including core network, access network and terminal) were adopted. Nb-iot series Row-mark plan release time for the end of 2016. This indicates that in China, Nb-iot already has the basic conditions of commercial scale in early 2017, the 2017 is expected to be China's Nb-iot scale commercial year. The meeting at the same time to the EMTC line of the project, time than the Nb-iot row of six months later, is expected to begin discussions in early 2017, June 2017 release.

Huawei helps Nb-iot sail with practice

In November 2015, 21 industry giants, including the mainstream operators of Huawei, equipment manufacturers, chip manufacturers and relevant international organizations, formally announced the establishment of the GSMA Nb-iot Forum Industry Alliance at the preparatory meeting of the Nb-iot Forum held during the Huawei Hong Kong MBB Forum. The aim is to accelerate the development of narrow-band IoT ecosystem. Six of the operators also announced that it would unite Huawei to set up six Nb-iot open laboratories around the world, focusing on narrowband networking business Innovation, industry development, interoperability testing and product compatibility validation.

Huawei has been working with partners on a global scale to conduct business application testing based on a pre-standard solution that is close to customer needs, stimulates industry innovation, and improves and enhances technical solutions:

· During the February 2015 World Mobile Congress, Huawei United Vodafone demonstrated an End-to-end business demo of water meter applications including chips.

· In June 2015, Huawei United Shanghai Unicom opened the End-to-end outfield test for intelligent parking applications.

· In November 2015, Huawei and Deutsche Telekom completed an end-to-end outfield test based on intelligent parking in Germany.

· In December 2015, Huawei United Vodafone and the local water company of Spain completed end-to-end testing of water applications on the Vodafone Spanish commercial network.

· April 2016, Huawei United Arab Emirates Telecom completed the application of Intelligent parking applications test.

· April 2016, Huawei United South East Australia Water, and local operators VHA, Optus together to open the network information reform.

· May 2016, Huawei and China Telecom, Shenzhen Water Group signed a strategic cooperation agreement to create intelligent water.

It is believed that with the standard freeze, more industry partners will join the Nb-iot camp. Nb-iot will also build the world's largest cellular networking ecosystem. More commercial applications will emerge in the second half of 2016 and explosive growth in the years to come. As many analysis agencies have predicted, the number of cellular networking connections will grow rapidly from 400 million connections in 2015 to 3 billion connections in 2020. This huge blue-sea market has been opened.
