NGN networks represent emerging architectures, frameworks, applications, applications, services, and business models. The challenges and opportunities of NGN’s are many and varied.
Self Organizing Network Benefits
Self-configuration: There will be a reduction in human interventions in deployment of network elements. Network elements shall automatically create logical associations with the remainder of the network. Self-optimization: There will be automation of tasks using measurements from the network equipment … Continue reading →
AT&T, Small Cells, and VoLTE
Driven by the growing surge for mobile broadband, carriers worldwide are investing in WiFi and small cell infrastructure as an economically efficient solution to expand network capacity and coverage. AT&T’s project Velocity IP (VIP) represents the deployment of more than … Continue reading →
RCS and Cloud Storage/Access
With the advent of 4th Generation (4G) cellular via the LTE standard, there is the potential for anywhere, anytime high bandwidth facilitates the potential for cloud-based storage/access of virtually any content and applications. End-users will be able to store music, … Continue reading →
Key Next Generation Network (NGN) Application Trends
Key Trends The Multi-screen Offering Strategy There is an emerging six screen strategy that includes the traditional (1) TV, (2) PC/laptop, and (3) mobile phone, along with the (4) car, (5) kiosks and (6) fixed station IP-based, communication devices. High … Continue reading →
Cost Savings the Ultimate Driver for IMS
Service providers will be under pressure to reduce the cost of providing services to improve margins. As they do, they will be looking for the most cost effective means to deliver services and the IMS model architecture will eventually help … Continue reading →
IPv4 vs. IPv6 in IMS
If IPv6 address is used, I-CSCF must be defined in DNS and will be used later in “Record-Route” header of SIP messages. I-CSCF will ask HSS for user information, such as the IP address of S-CSCF. But if IPv4 address … Continue reading →
Changing the Service Creation Paradigm
Service creation is a growing focus among service providers in both wireless and wireline networks. Each group is faced with new challenges and some common dynamics affecting both sides of the industry. Reduced top-line revenue among wireline carriers and a … Continue reading →
Role and Importance of the IMS Control Plane
The IP Multimedia Subsystem (IMS) Control Plane contains all the call control and authentication functions for call setup, handoffs, and billing recording. The two most important Control Plane functions are the HSS (Home Subscriber Server) and the CSCF (Call Session … Continue reading →
Convergence of Features will Progress over Time
IMS is a model architecture that carriers will slowly move to adopt in stages. Just as the architecture will evolve and scale gradually, so will the degree of convergence that is achieved over time. Stage 1: Price bundling of existing … Continue reading →
Quality of Service and Latency Sensitive Applications in Next Generation Networks
Quality of Service (QoS) is a requirement for latency sensitive, real time applications such as voice, particularly Voice over IP (VoIP), as well as real time video services, and multiparty applications (Push to Talk (PTT), Video Sharing, Video Conferencing and … Continue reading →
