  Let's have a look on 5g call flow of registration procedure . Source-ScienceDirect.com As you can see in the above image that UE has to register itself before using the 5g services . The registration are of several types which are listed down below: Initial Procedure Registration Periodic Procedure Registration Mobility Procedure Registration Emergency Procedure Registration In Initial Procedure, when UE is Power-On and ready for registration .Periodic procedure is to keep watch of UE status , if it become inactive , due to some reasons like  battery discharge .Mobility procedure is when UE move to another location and then it have to register it, under this procedure.Emergency procedure is when there is any emergency like situations ,then this procedure is used. Now lets a deep dive how a UE Register itself to a 5g network for using its services. 1. For a registration from UE , it send a registration request to RAN(gNB). Now RAN sends this request to the AMF(Access and Mobility

  For Part-1 of RAN Protocol Stack : https://tomar102003.blogspot.com/2022/09/ran-protocol-stack-overview-part-1.html For Part-2 of RAN Protocol Stack : https://tomar102003.blogspot.com/2022/10/ran-protocol-stack-part-2.html So , in part 2 we have discuss till the MAC Layer now we have to discuss PHY Layer which is left in User-Plane , RRC Layer and NAS Layer of Control-Plane as all left layer of Control-Plane are same as User-Plane which we have discussed already in part-2 of this series. 1. PHY ( Physical ) Layer : Source -techplayon.com As you can see in above image that Physical Layer getting its services from the Transport Channel(which is a part of MAC Layer) ,hence getting services from MAC. So first take a look on the Physical channels: PDCCH ( Physical Downlink Control Channel ) :This channel is used for downlink control information like scheduling sessions. PBCH ( Physical Broadcast Channel ) : This channel have the system information which is used by UE for getting the MIB(

For Part-1 of RAN Protocol Stack : https://tomar102003.blogspot.com/2022/09/ran-protocol-stack-overview-part-1.html In the below image, we have all layers of User Plane Protocol Stack . Now From top to bottom, we will go through each layer with wide description of each functions within each layer.  source - techplayon.com 1. SDAP ( Service Data Adaptation Protocol ): Functions of this layer are : QoS ( Quality of Service ) Flow Handling : This layer mapped the quality of service , QFI (Quality of Service Flow ID) to the appropriate radio bearer between the gNodeB (RAN) and the UE (User Equipment or Device).           QFI(Quality of Service Flow ID): It is used to differentiate between different quality of service within the PDU's (Protocol Data Unit) Sessions.           Below Image give you the overview about what we describe above. source - techplayon.com As you can see that QoS Flow are giving their QFI for differentiate between different quality of service within a PDU Sessio

 Lets have a look on Ran Protocol Stack. NOTE : This Part only give the overview of RAN Protocol Stack and we will go deep in the subsequents parts. We have seen from the above image that there are two types of RAN Protocol Stack: User-Plane Protocol Stack Control-Plane Protocol Stack Each layer which are shown in the diagram uses the information from the below layer and provides services to the above layer. (Both in User Plane and Control Plane Protocol Stack). In User Plane Protocol Stack information is communicate between the User Equipment (UE) and gNB( 5G RAN). RAN-Random Access Network. In Control Plane Protocol Stack information is communicate between the User Equipment and gNB and the Core-network. First Discuss about the layers of User-Plane Protocol Stack   SDAP ( Service Data Adaptation Protocol ) - This layer is responsible for QoS (Quality Of Service) Flow Handling . PDCP ( Packet Data Convergence Protocol ) - This layer is responsible for Header Compression,In Sequen

 Let's Have a look on 5g NR(New Radio) Frame Structure. Introduction In   5G NR , each frames has a time durations of 10 ms and frame are nothing but one segment of the data which is intend to send from sender(source) to receiver(destination). Now , each frame compromises of 10 subframes , which gives us the duration of each subframe which is about 1 ms. After frame are divided into subframe , now each subframe are divided into slots , whose number is depend on the numerology formula (2^ µ ) and  µ  has a range from zero to four . Lets have a look what does it really mean. As slots number are depend on the 2^ µ  and if we take  µ 's value as zero, we get 2^ µ  as 1, this means here each subframe divided into one  slot . Similarly for  µ's  value as 1, we get 2^ µ  as 2,now each subframe divided into two slots . Same procedure for the rest  µ's  value. Below image give you a diagrammatic overview about what we have discussed above. For the sake, only see the first

  A 10 min read will give you the overview of Kubernetes . LETs Start!!. Overview what we study in this whole: What is Kubernetes . Kubernetes  Cluster Architecture.  Different Components of Kubernetes. What is Kubernetes ? Kubernetes is a  tool by which we can orchestrate or manage the containers .Thus , it is a container manager which keep an eye on every things which make to manage containers. It is portable , open source , extensible which is also used for automation. Its is abbreviated as k8s as between " K " and " s " there are eight letters for making it easy to speak . Kubernetes provide you with the following features: Storage orchestration : It provide you to automatically bound to storage system of your choice local storage , public cloud providers , etc. Automatic rollouts and rollbacks : You can describe the desired state of your deployment and its automatically shift the actual state to your desired state at a controlled rate. Self-healing : It scale
