    Ultra IoT C-SGN Overview
    The Ultra IoT C-SGN (CIoT Serving Gateway Node) is a combined node EPC implementation option that minimizes the number of physical entities by collocating EPS entities in the control plane and user plane paths. C-SGN combines the MME, P-GW and S-GW functions to provide a highly optimized CIoT solution.

    The Ultra IoT C-SGN runs on virtualized environments to support Cellular IoT (CIoT) traffic. The CIoT EPS Optimizations in this release provide improved support of small data transfer.

    The topics in this chapter include:

    Overview of IoT
    CIoT EPS Optimizations
    Overview of IoT
    The Internet of Things (IoT) is a computing concept where everyday objects have internet connectivity and they can collect and exchange data. The IoT network comprises of a wide variety of physical devices, vehicles, buildings, and any other devices or objects used in our daily lives. IoT is expected to bring a revolution of tremendous growth opportunities by bringing millions of new set of devices, applications and new set of enablement of protocols/technologies into the network.

    The IoT devices use MTC (Machine Type Communication). The key objective is to provide solutions to support high efficient handling of tracking devices using small data transmissions for ultra-low complexity, power constrained, and low data-rate IoT devices, called CIoT devices. The main requirements for IoT devices is EPS optimization for small data transfer.

    NarrowBand IoT (NB-IoT) is a narrowband radio technology that is optimized for IoT in 3GPP Release 13. Optimizations on the core network are applicable to both NB-IoT RAT and EUTRAN RAT (for eMTC / LTE-M devices).

    CIoT Overview
    Platform Requirements
    Licensing Requirements
    Standards Compliance
    CIoT Overview
    Cellular Internet of Things (CIoT) technology is an important branch of IoT. The CIoT devices use small data transmissions for ultra-low complexity as they also use low data-rates and have power constraints. While the number of CIoT devices in the network might increase exponentially, the data size per device remains small.

    The following enhancements are required to support CIoT devices:

    Minimize system signaling load over the radio interface
    Provide adequate security to the EPS system
    Improve battery life of the devices
    Support delivery of IP data
    Support delivery of non-IP data
    Support of SMS
    Extended coverage
    Low cost
    The EPS optimized for CIoT supports different traffic patterns as compared to normal UEs and supports only a sub-set and necessary functionalities as compared with the existing EPS core network, in a single logical entity known as the CIoT Serving Gateway Node (C-SGN). The C-SGN is a new node specified for optimizations that consolidates functions from control plane node (MME) and user plane nodes (S-GW, P-GW, and SAE-GW).

5G Deployment Option-3/3a/3x

Image
Home                 LTE                NB-IoT            5G(NR-NSA)   Hi Guys today we are learning about 5G deployment options, if you want to know more about other 5G deployment option please  click here Option 3: EN-DC (EUTRA-NR Dual Connectivity) Option 3 represents a network having both LTE and NR radio access, but using only the EPC core of LTE to route the Control signals. In this option, LTE is used as the control plane anchor for NR, and both LTE and NR are used for user data traffic.(user plane). It could also be called as Non-Standalone (NSA) NR in Evolved Packet System. The only difference between Options 3 and 3A is based on whether the user plane data is sent to NR directly or via the LTE RAN. This standardization was concluded in 3GPP Rel-15. This is a possible first step in the migration towards 5G-SA. This option will be most attractive for operators which have early deployments of 5G NR access systems in areas where legacy eNB and EPC a

Soft Handover vs Hard Handover

Home                 LTE                NB-IoT            5G(NR-NSA) Now before we move to other things like measurements in handover, handover decision, handover procedure, handover interruption time, and mobility robustness optimization, let us take a look into difference between soft handover and hard handover. Soft Handover Hard Handover The handover in which radio links are added and removed in a way that MS always keeps at least one radio link to the UTRAN is known as soft handover. The handover in which all the old radio links in MS are removed before the new radio links are established is known as hard handover. This can also be simplified as make before break This can also be simplified as break before make As call drop rate is lower this handover is used to lower the rate of call drop. In this case higher rates of call drops are found Why soft handover is not included

DRX (Discontinuous Reception)

Image
Home                 LTE                NB-IoT            5G(NR-NSA)   What is DRX and DRX active period? What channels does it monitor in active period? Data transmission between UE and their base stations(eNodeB) uses radio frames with10ms duration, where in each radio frame consists of 10 1ms( 1 frame=10ms duration=10 subframe) subframes. Physical Downlink Control Channel (PDCCH) at the beginning of each subframe indicates whether there is data for UE to receive or not. Devices has to monitor these PDCCHs in each subframe so that it can find out whether they carry any data to receive. Because devices do not receive data in every subframe, this monitoring process naturally leads to high battery consumption.  What is the purpose of DRX? The main purpose of DRX is to lower battery consumption when there is no UL/DL data. means, when there is no traffic(DL/UL) that time devices enter into sleep mode (with RF module turned off) for some period of time as configured by

Authentication in LTE

Home                 LTE                NB-IoT            5G(NR-NSA)   What is Authentication and what type of Authentication is used in LTE? Authentication is a process by which both the UE and Network check whether the other party is authorized to communicate with them. In LTE and WCDMA, a mutual authentication process is used i.e. the Network checks whether the UE is authorized to camp on it and the UE also checks whether it is trying to camp on is the correct Network. The UE becomes authorized to camp on a network by subscribing to the network. In LTE, EPS AKA i.e. Authentication Key Agreement procedure is used for Mutual Authentication. Why is Authentication required from both sides in LTE? The UE needs to be authenticated by the NW to check whether it has subscribed to the NW or not. Only UEs which have a valid subscription should be allowed to camp on the NW. The NW should also be authenticated by the UE because if the UE does not check its

Home                 LTE                NB-IoT            5G(NR-NSA)   As per readers request this article is based on some 5G abbreviations (PCell,spCell,Scell,PSCell,MCG.SCG,Master-Node,Secondary-Node) for better understanding. What is Master Node? Master node:  The node (radio access node) that provides the control plane connection to the core network in case of multi radio dual connectivity (MR-DC). For example, it can be master eNB in EN-DC, a Master ng-eNB in NGEN-DC What is Secondary Node? Secondary node:   the radio access node, with no control plane connection to the core network, providing additional resources to the UE in case of MR-DC. For example, It may be an en-gNB in EN-DC or a Secondary ng-eNB (in NE-DC). What is MCG? MCG: Master Cell group It is a group of serving cells associated with the Master Node, comprising of the PCell   and optionally one or more Scells.  (see figure shown above) MCG and SCG are concepts under

DC Carrier in NR

Image
Home                 LTE                NB-IoT               5G(NR-NSA) In this article, we will learn the basics of DC Carrier and why it is needed. Why in NR, DC subcarrier is not reserved like LTE? With legacy LTE (4G) it was decided that all devices (UE) should be capable of the maximum carrier bandwidth of 20MHz (UE can also support 10/15/5/3 MHz). This was a reasonable assumption at the time given the relatively modest bandwidth compared to NR, Whereas NR is designed to support very wide bandwidths up to 400MHz (for FR2) and 100Mhz (for FR1) for a single carrier. As well as NR supports multiple numerologies on the same transmitted carrier frequency. It is not necessary that all devices can support up to 400 MHz Bandwidth, hence in NR BWP concept is introduced. (To learn more about BWP Click here ). Note: in the above and below NR case figure, we assume that for each and every BWP have configured some  txDirectCurrentLocation  value.     As shown in the a

Home                 LTE                NB-IoT            5G(NR-NSA) Hi Guys today we are learning about 5G deployment options, if you want to know more about other 5G deployment option please  click here Option 7: Deployment Option 7 represents a deployment scenario in which the Next Generation Core (NGC) will be used with a mixture of LTE and NR radio.  Next Generation signaling will be used but it will be routed via the LTE RAN because the LTE network is more fully built out and thus more reliable for handling signaling.  Options 7 and 7a differ on whether the user plane data is sent to NR directly or via the LTE RAN. 7/7A/7X require an eLTE upgrade of the existing LTE network at the start. (Difference is UP path Non Standalone ( Dual Connectivity 4G/5G ) Option 7/7A: NSA NR in 5GS. This option is particularly attractive for areas in which legacy LTE eNBs and the EPCs are ready to be upgraded to ngeNBs and the 5GCs.  From the point of
