5G NR (New Radio) is the radio access technology used in 5G networks. It is responsible for establishing and maintaining the connection between a 5G device and the network.

TCP, UDP, and SCTP are all transport protocols that can be used over a 5G network. TCP is a reliable protocol that ensures that data is delivered in order, while UDP is an unreliable protocol that is used for applications that require low latency. SCTP is a reliable protocol that is designed for high-performance applications.

MIPv6 (Mobile IPv6) is a protocol that is used for managing the mobility of 5G devices. It allows a 5G device to maintain its IP address while moving between different access points.

TLS, SSL, and IPsec are all security protocols that can be used to secure data over a 5G network. TLS and SSL are used to secure data at the application layer, while IPsec is used to secure data at the network layer.

DiffServ, IntServ, and RSVP are all QoS protocols that can be used in a 5G network. DiffServ is a simple QoS protocol that classifies traffic into different classes and provides different levels of service to each class. IntServ is a more complex QoS protocol that allows applications to specify their QoS requirements. RSVP is a signaling protocol that is used to reserve resources for QoS-sensitive applications.

802.11ax, 802.11ac, and 802.11n are all Wi-Fi protocols. They are not used for discovering and connecting to 5G networks.

GPS, GLONASS, and BeiDou are all global navigation satellite systems (GNSS) that can be used to provide location-based services in a 5G network.

NTP, PTP, and GPS can all be used to synchronize clocks in a 5G network. NTP is a network time protocol that uses a hierarchical system of time servers to distribute accurate time information. PTP is a precision time protocol that uses a peer-to-peer system to synchronize clocks. GPS is a global navigation satellite system that can also be used to synchronize clocks.

RRM (Radio Resource Management) is a protocol that is used for managing the radio resources in a 5G network. It is responsible for allocating radio resources to different users and services, and for ensuring that the radio resources are used efficiently.

MBMS (Multimedia Broadcast Multicast Service) and eMBMS (Enhanced Multimedia Broadcast Multicast Service) are both protocols that can be used to provide multicast and broadcast services in a 5G network.

NSI (Network Slice Instance), SBI (Slice Broker Instance), and NSSI (Network Slice Selection Instance) are all protocols that can be used to provide network slicing in a 5G network.

MEC (Mobile Edge Computing) is a protocol that is used for providing edge computing services in a 5G network. It allows applications to run on devices that are located close to the user, which can reduce latency and improve performance.

XR (Extended Reality) is a protocol that is used for providing VR and AR services in a 5G network. It allows users to experience virtual and augmented reality content on their devices.

AI (Artificial Intelligence), ML (Machine Learning), and DL (Deep Learning) are all protocols that can be used to provide AI services in a 5G network.

LPWAN (Low-Power Wide-Area Network), NB-IoT (Narrowband IoT), and LTE-M (LTE for Machines) are all protocols that can be used to provide IoT services in a 5G network.
