📱 5G Standalone (SA) Voice Over New Radio (VoNR) Call Flow 📱 In 5G Standalone (SA) networks, Voice over New Radio (VoNR) enables voice services directly over the 5G network, bypassing the need for 4G LTE networks (unlike VoLTE). 1. Initial Registration User Equipment (UE) registers with the 5G Core Network (5GC): The UE (mobile device) initiates a registration procedure with the 5G Core Network. During this process: The 5G Core authenticates the UE to ensure it is a legitimate device. The UE obtains an IP address, and security keys are established for encrypted communication. The 5G Core assigns an Access and Mobility Management Function (AMF) to manage signaling and mobility for the UE. Policy and Subscription Checks: The 5G Core checks the subscriber’s policy and authentication details to ensure the UE is allowed VoNR services. 2. Session Establishment Session Management Function (SMF) Configuration: The SMF in the 5G Core is configured for session management, setting up a Quality of Service (QoS) profile for the VoNR session, which includes guaranteed bit rate (GBR) parameters specific to voice. Packet Data Unit (PDU) Session Establishment: A PDU session is established between the UE and the User Plane Function (UPF), carrying the voice data over the 5G network with a guaranteed QoS profile. This is similar to a dedicated bearer in LTE. 3. Call Setup (IMS Registration) IMS Registration: The UE initiates an IMS (IP Multimedia Subsystem) registration. The IMS handles voice services over the 5G network and is necessary for VoNR. PCSCF Discovery: The UE identifies the Proxy Call Session Control Function (PCSCF) in the IMS. The PCSCF assists in setting up, modifying, and terminating voice calls. 4. QoS Flow Setup Dynamic QoS Flow Establishment: For voice traffic, a dedicated QoS flow is established with the required priority and bit rate. This is a dedicated flow on top of the existing PDU session. Mapping QoS Flow with Radio Bearers: The QoS flow for the voice session is mapped to a specific radio bearer on the New Radio (NR) interface, ensuring that the voice packets receive priority transmission over the 5G air interface. 5. Media and Voice Transmission Media Flow Setup: Once the QoS is established, media flows for the voice packets are initiated. The UE and network exchange Real-time Transport Protocol (RTP) packets carrying the actual voice data. 6. Call Maintenance and Handover Handover Support: If the UE moves during the call, the 5G network provides seamless handover mechanisms (e.g., intra-NR handover or inter-frequency handover) to maintain call continuity. 7. Call Termination SIP BYE Message: When either party decides to end the call, the UE or the IMS network sends a SIP BYE message to terminate the session. Tear Down QoS Flows and PDU Session: The 5G network releases the dedicated QoS flow and any radio bearers associated with the call.

The “real” 5g The 3GPP had introduced 2 options for 5g upgrades from LTE: 1️⃣ Standalone (SA): This option is designed to work only with the new 5g radio (NR). 2️⃣ Non- Standalone (NSA): This architecture leverages existing LTE infrastructure. The NSA, put simply, allows the operator to still show the 5g symbol next to the bars on our phone but does not really provide the full capability of 5g. ❌ Specifically, services such as URLLC, network slicing etc are not possible in the NSA option. Though the NSA may have been designed with the intent to provide a faster migration path to 5g, the thought is that it may have caused the telcos to become lethargic and affected the customer's experience in a negative way. 5g deployments based on NSA allow for a faster deployment but also stifles the realization of the full potential of 5g. 📈 But things are picking up. 👉🏽 49 operators in 29 countries have deployed public 5G SA networks.   As very successfully example has been Jio which has established itself at the forefront of 5G SA deployments in India. Its decision to choose 5G SA over non-standalone (NSA) is a forward-looking strategy that enables Jio to provide truly differentiated 5G services in a highly competitive market. 📳 On the devices front, around 1700+ devices have been announced with claimed support for 5G SA. The number of 5G SA devices as a percentage of all 5G devices announced has been steadily climbing. They accounted for 68.1% of 5G devices in March 2024. document source: GSA_5GSA report #5g #network #telecom #mobilenetworks #VPspeak [^468]

The upcoming 5G Advanced Release is the first release in the 5G Advanced series of specifications from 3GPP. It is expected to be finalized in Q2 2024.

To fully realize the benefits and new features introduced in 5G Advanced Release 18, a complete end-to-end 5G standalone (SA) system is required. The 5G SA architecture consists of a new 5G Core (5GC) network and 5G New Radio (NR) in the Radio Access Network (RAN). The 5G SA architecture is designed to provide a more efficient, flexible, and scalable network compared to the earlier Non-Standalone (NSA) architecture, which relied on the existing 4G LTE core network. The 5G SA architecture enables: 1. Native network slicing support allows operators to create multiple virtual networks with different performance characteristics on a single physical infrastructure. 2. Service-Based Architecture (SBA) in the 5G Core, enabling a more modular and flexible network design with improved scalability and easier integration of new services. 3. Edge computing capabilities allow for deploying processing resources closer to end-users, reducing latency, and enabling new use cases. 4. Enhanced security features, such as stronger encryption and authentication mechanisms. 5. Improved support for massive IoT deployments and mission-critical applications with stringent latency and reliability requirements. To take full advantage of the features and enhancements introduced in 5G Advanced Release 18, mobile network operators must deploy a complete 5G SA system, including the 5G Core and 5G NR in the RAN. This will require significant investments in network infrastructure.

Backhaul, Fronthaul, and transmission of 5G #1 Introducing 5G in Transmission Mobile networks evolve, with new system generations bringing higher speeds and new service capabilities, with improved system architectures and novel radio technologies. With this evolution, 5G mobile backhaul and fronthaul play an increasing role, with new challenges in matching the new 5G system capabilities. With 5G, higher peak rates are surely an important enhancement, as was the case with 4G. This is just a single item, however. 5G is the most versatile mobile system so far, supporting not only traditional mobile broadband but also new industrial and enterprise use cases with building blocks like network slicing for unique services. URLLC services extend the 5G capability to applications that were previously not possible in a mobile system. The 5G network is built to serve different use cases and customers, which also impacts transmission. New high-frequency bands mean not only high capacity but also a potentially huge number of small cells. Further, radio signals from outdoor sites are heavily attenuated indoors. So, indoor solutions will be required for coverage with related connectivity solutions. Disaggregation of the 5G radio access and related radio clouds opens up a new type of network implementation, where existing servers and computing platforms can be leveraged to support virtualized or containerized network functions. At the same time, the opening of the interfaces between network elements allows multi-vendor deployment and operation. With 5G radio energy efficiency is improved and network level optimizations allow further energy savings. Packet-based fronthaul is a genuine new area, which evolved from previous industry proprietary solutions to use common packet networking technologies, which in turn better allow shared packet infrastructure in fronthaul also, but with special emphasis on the time-sensitivity of fronthaul traffic flows and synchronization. This all shows the range of new tasks there are for 5G mobile backhaul and fronthaul since there is no longer a single use case or single implementation approach for radio networks. As transmission is all about efficiently connecting mobile network elements, there will be many different needs based on the radio cloud and the level of disaggregation targeted, and based on services intended to be delivered over the system. These all have to be supported on the very same backhaul and fronthaul network. For example, essential topics like transmission latency and capacity requirements all depend on the use cases as well as the type of disaggregation and virtualization deployed.
