The world's first eMTC VoLTE-based application is grounded by Qualcomm Ericsson and China Unicom

During the 2017 World Mobile Communications Conference Shanghai Exhibition, China Unicom and Ericsson and Qualcomm jointly announced that the first successful implementation of eMTC (Cat-M1) VoLTE-based application demonstrations on the world can make better use of existing network support. The scale of IoT terminal access, its voice call capability can support a more rich application scenarios. At the exhibition site, the tripartite cooperation demonstrated two application scenarios of Cat-M1 VoLTE - fire alarm trigger panel and GPS emergency tracking device.

eMTC (Cat-M1) LTE Category M1 is a wireless technology that provides high mobility, low cost, wide coverage, flexible deployment and low latency. By enabling VoLTE voice support on the Cat-M1 network, ensuring that Cat-M1-based devices can make voice calls can help operators deploy networks at low cost to meet the needs of eMTC-based multiple mobile broadband and IoT communication service use cases. . Previously, China Unicom and Ericsson and Qualcomm successfully realized the data communication of Cat-M1 on the existing network of China Unicom Beijing Branch.

The device integrates the Qualcomm® MDM9206 global multimode LTE IoT modem, supports all frequency bands of Cat-M1 and Cat-NB1 worldwide, supports voice functions, and has power saving mode and eDRX in the technology. At the same time as the call is connected, the location information is sent to the other party through the eMTC network, so that the rescue can be obtained in time. According to Ericsson R&D personnel, this alarm device does not require wired deployment, which enables a wider coverage, energy-saving features, and communication with LTE terminals for use in industry sectors similar to climbers.

Dr. Durga Malladi, vice president of engineering technology at Qualcomm, said that the development of the Internet of Things is inseparable from the support of multi-mode and multi-service devices. Qualcomm MDM9206 was developed for this application, low power consumption and cost-effective. The successful demonstration of Cat-M1 VoLTE shows that 5G-based services will become a major trend in the future. Qualcomm hopes to bring the advantages of LTE IoT to people and organizations all over the world. In the future, the industry will deploy more devices like meters. .

The VoLTE application based on LTE IoT Cat-M1 has many technical advantages, such as strong mobility, low equipment cost, strong coverage, flexible deployment and low latency. The technical solution has broad application prospects. At the end of last year, China Unicom and Ericsson and Qualcomm realized eMTC (Cat-M1) data transmission on the live network in Beijing, and jointly promoted the application demonstration of this technology in the field of shared bicycles. This marks the maturity of the LTE IoT industry ecosystem and is a model for IoT technology leaders to work together to promote innovative applications of the Internet of Things. With the rapid development of China's IoT business and the rapid deployment of the network, this technology provides a tool for operators to cope with low-cost demand and diversified business needs to support voice over LTE narrowband.

On May 12 this year, China Unicom released the world's largest city-level NB-IoT trial commercial network in Shanghai. "China Unicom has been actively promoting the development of the Internet of Things, relying on the world's leading 4G FDD network to accelerate the deployment of cellular IoT networks and promote business. "Application of scale", Deputy General Manager of China Unicom Shao Guanglu said that the cooperation between China Unicom and Ericsson and Qualcomm on eMTC is another new exploration of Unicom's application of innovative technologies in Internet of Things. . We will rely on the boutique network to open cooperation in the platform, business and terminal areas, realize the integration of all things, promote social intelligence and win the future. In the future, China Unicom will launch more eMTC-based businesses. In addition to large companies such as Qualcomm and Ericsson, China Unicom is willing to cooperate with more startups.

Ericsson is committed to leading the development of IoT technology and providing a rich Internet of Things business type to global carrier customers. Chris Houghton, president of Eric Northeast Asia, said that as a strategic partner of China Unicom, Ericsson hopes to help China Unicom's IoT development strategy and bring together the unlimited potential of the network society through its leading technology and global business experience. It is believed that the mature application of the fire alarm and GPS first aid demonstrated today will enable more security-based applications to come to the future.

Emergency communication panels are widely used in various scenarios, such as fire alarm trigger panels, emergency assistance points on cities and highways, and emergency emergency calls. With the support of LTE IoT Cat-M1 technology, these emergency communication devices can be converted to wireless connections for easier deployment. Cat-M1 VoLTE technology establishes voice communication between the alarm point and the emergency center. In addition, Cat-M1 devices can be managed centrally through the Ericsson IoT Accelerator Platform, making it easier to configure end-to-end services to meet different needs.

In the actual application scenario, when a fire occurs, the trapped person presses the fire alarm trigger panel to notify a number of relevant departments, such as a fire alarm center, an emergency center, and a building property. The trapped person can describe the specific situation of the fire scene through voice and rescue personnel, and get the most timely guidance to improve the efficiency of emergency communication.

GPS emergency tracking device

The LTE IoT Cat-M1-based GPS tracking device allows users in remote locations to send location information via data and establish connections with family or rescue departments. Compared with traditional technologies, devices using new technologies have a wide range of coverage, longer battery life and so on. With the support of VoLTE function, in an emergency, users can also use this device to establish emergency voice communication links with others to improve communication efficiency.

At the demonstration site, engineers at China Unicom, Ericsson and Qualcomm booths can implement point-to-point Cat-M1 VoLTE calls via the Mercury P99 GPS Tracker with Qualcomm MDM9206 global multimode LTE IoT modem. For example, when a GPS tracking device of China Unicom's booth issued an emergency call to the corresponding equipment of the Ericsson booth, a point-to-point communication connection was established.
