Radisys Optimizing VAS for Greater Revenue Generation
The document discusses optimizing value added services (VAS) for greater revenue generation. It covers 5 technology trends that are optimizing VAS delivery, including the growth of LTE, small cells, offloading data to WiFi and the internet, and machine-to-machine communications with policy enforcement. It also discusses how an IMS architecture can generate VAS revenue through services like VoLTE, video calling, and conferencing using a media resource function (MRF). The presentation concludes by emphasizing how the MPX-12000 MRF platform supports VoLTE, video, and other VAS through high definition voice and video processing capabilities.
IMS Naming Identity
This document discusses various identities associated with users of IP multimedia services:
- Private User Identity (IMPI) is assigned by the home network operator and is used for registration, authorization, administration, and accounting. It takes the form of a Network Access Identifier.
- Public User Identity (IMPU) is used by a user to request communication with another user. It takes the form of a SIP URI or Tel URI.
- An IMS subscription associates one or more IMPIs with one or more IMPUs. Public service identities identify specific resources or services using SIP or Tel URIs.

2G / 3G / 4G Overview
5G Primitives
5G New Services and Technologies
5G Spectrum Band (mmWave)
5G-NR: 5G New Radio
5GC: 5G Core
5G Basic Call Flow Analysis
VoWLAN: Call Quality
1) VoWLAN call quality can be excellent, comparable to DECT and VoLTE, but is degraded by delay and jitter caused by congestion on the WLAN.
2) 802.11 contention introduces delay and jitter as devices must wait to transmit over the shared medium. WLAN QoS aims to prioritize voice packets to reduce this impact.
3) Experiments show that with medium WLAN congestion, downstream unprioritized voice is degraded but prioritized voice is protected; with heavy congestion both are affected.
5G RAN fundamentals
The document discusses 5G radio access network (RAN) fundamentals and architectures. It describes how the RAN has evolved from previous generations with more distributed and virtualized architectures in 5G. Key aspects of 5G RAN covered include centralized/virtualized RAN, Open RAN specifications, functional splits, and new concepts like network slicing and multi-access edge computing. Example use cases are also mentioned.
Towards a 5G Operating Platform Infrastructure-agnostic Orchestration
This presentation and demo will show an overarching orchestration software architecture that is based on a continuous advertisement of capabilities and resources from underlying infrastructure-layer domains, which allows the orchestration to adapt its service logic to exploit the most up-to-date capabilities. The feasibility will be shown to setup a complex NFV service across multiple domains, such as two OpenStack instances connected by an SDN network, where all the service functions (e.g. NAT, firewall, etc.) are launched in the datacenter and the intermediate SDN network is used only to connect all the different components together. However, when the SDN network advertises also the capability to host a given set of network applications (e.g. a NAT), the orchestrator will adapt its service logic and it will instantiate part of the service in the datacenter (e.g. as virtual machines), part in the SDN domain (e.g. as ONOS applications), hence enabling more aggressive optimization strategies in the overarching orchestrator.

IMS presentation
IMS is an architectural framework that uses SIP to deliver IP multimedia services to mobile users. It consists of common core elements, enablers, and support systems arranged in three layers. The control layer contains various nodes that handle signaling and session management, including the P-CSCF for access, I-CSCF for routing, and S-CSCF for authentication and services. Together these elements establish and manage multimedia sessions between IMS subscribers and networks.

Use Cases, Architecture evolution, challenges including interconnect and roaming, and Steps towards 5G
OPNFV with 5G Applications
Juha Oravainen, Nokia, Tapio Tallgren, Nokia
In the future factory robots will communicate wirelessly and cars on the highways will exchange the information with each other. This requires extremely low latency mobile networks, known as 5G. This network will run on telco grade cloud platforms of which OPNFV is one example.
The first cloud radio access networks have already been deployed to operators. More is needed with future technologies/networks as more functionalities will be moved to the cloud. This talk tells what is needed to overcome low latency and high availability challenges with cloud platforms. At Nokia we are continuously evaluating the latest OPNFV SW on Nokia HW with radio VNFs to guarantee interoperability with open source components.
Cellular LPWA for the IoT
This document discusses Sierra Wireless' work on cellular Low Power Wide Area (LPWA) technologies for the Internet of Things. It provides details on Sierra Wireless' LTE-M demo at Mobile World Congress 2016, showing the first LTE-M module supporting power saving mode and extended discontinuous reception features. These features allow for ultra low power operation, extended battery life, and global coverage on existing LTE networks. Sierra Wireless discusses their leadership in supporting all 3 standardized cellular LPWA technologies and taking LPWA to commercial availability in 2017.
