Introduction On behalf of one of the critical emerging 5G services, Internet of Things (IoT) will govern the number of connected terminals and impact 5G patterns, quality of experience (QoE) and quality of service (QoS), all of which will influence hackhaul specifications. Accomplishing with the aggregate data demand and network capacity demand soar up, more eNodeB will be scheduled to meet the QoS that is critial for IoT to be successful. One of major objectives of 5G services is to supply ultra-high capacity per terminal, improve spectrum efficiency. Along with the development of autonomous networks and manufacturing industries, the demand for increment capcity will be exponential growth.

Due to the diversity of sensors such as speed, pressure, temperature, humidity, height, video, image, voice and location sensors, information detected by these sensors transform comprehensively. 2.3 LTE-A MTC LTE-Advanced technology, the soul of 4G network connectivity, will evolve to supply attacting characteristics that provide a large number of high performance and low cost IoT devices. These devices extend coverage for challenging locations, energy saving for applications requiring long battery life and optimizations to deploy very large numbers of devices per cell. LTE-based MTC solutions create development in diverse entities of MTC ranging from home and industrial automation to consumer electronic devices such as connected wearables. LTE-based MTC solutions serve as one type of IoT service on the strength of its ubiquitous connectivity, more efficient energy saving, higher coverage and faster data rates of up to 1 Mbps [1]. 2.4 Automotive Cellular mobile services are enabled to supply connectivity to the surrounding automobile as the demand for ubiquitous coverage and bi-directional real-time communication to the advantages of vehicle networks.

Traditionally, mobile networks have been planned for low latency, high throughput consumer traffic. MTC optimizations to 5G is used to extend coverage for low throughput devices deep deployed within buildings such as in basements which consequentially reduce signaling traffic and device cost, and improve battery life. Meanwhile, IoT optimized wide area networks which are under developed and deployed. 3.3 Cellular core network 5G core network functions make two major forces for IoT services and devices. One is the current ongoing MTC and another is the application of Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies in the 5G core network that create novel capabilities that can enable a plenty of use cases more efficiently including IoT. MTC is concentrated on 5G cellular system enhancements for IoT services and develop for low complexity, low cost and low power consumption as well as efficient small data transmission devices. NFV and SDN technologies build a modular based core network architecture where the core network can be dynamically ‘scaled’ and ‘sliced’ depended on IoT use cases, categories of devices. It is conceivable that a network operator can create mobile core instances suitable for IoT. The blending of these novel technologies will lead to an access agnostic and 5G core network that will backup the various use cases of telecommunications. not-yet-known not-yet-known not-yet-known unknown 3.4 Connectivity platform By designing a platform for handling SIM pre-provisioning, provisioning, activation, deactivation and self-diagnosis of device communication issues, the demand for bulk provisioning has driven 5G operators to reduce their operations cost.
