Slovak Telekom Case Study - Enabling enhanced services through IMS technology
- Mobile integration status
- Overview of new IP based services
- Evolution of the integration platform
Presented at IMS World Forum 2013 in Barcelona, Spain.
NGN is a packet-based network able to provide Telecommunication Services to users and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent of the underlying transport-related technologies. It enables unfettered access for users to networks and to competing service providers and services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.
The objective of study is to guarantee QoS for multiple service class traffic in a multiple connection environment and to examine a case of QoS deployment over a cellular WiMAX network. In particular, the thesis compares the performance how much bandwidth for voip
Service Broker for VOIP IMA WebRTC and old telecom networksALTANAI BISHT
SB( Service Broker ) enables us to make use of existing applications and services from Intelligent Network’s SCP ( Service control Point ) , IMS’s Application Server as well as other sources in a harmonized manner .
Service broker is a service abstraction layer between the network and application layer in telecom environment.
This document describes the process of integrating a Service Broker with service harmonization and orchestration in a telco environment .
In a hyperconnected economy, businesses need tools that empower employees to work together and get more done, anytime, anywhere, using the devices they prefer. SIP Trunking enhances mobility and presence, and provides end-to-end unified communications applications, among other advantages. This paper explains how companies can simplify company-wide business communications using SIP-to energize communications, productivity, collaboration, and business growth.
This research work investigates and improves the performance of Voice over Internet Protocol (VoIP) traffic using IPV4 and IPV6 over WiMAX networks and the impact of various voice codec schemes and statistical distribution for Voice over Internet Protocol (VoIP) over WiMAX has been investigated in detail.
Session Border Controllers presontation by Jonathan Richards - VON 2005
SBCs control real-time session traffic at the signaling, call-control, and packet layers as they cross a packet-to-packet network border between networks or between network segments
SBCs are critical to the deployment of VOIP networks because they address the inability of real-time session traffic to cross network address translation (NAT) device or firewall boundaries
A multi tenant platform for sms integrated servicesIJCNCJournal
This paper presents the design and development of a Linux based infrastructure and platform for a
wholesale service provider to offer SMS integrated services to retail providers for resale. The multi-tenant
platform, capable of providing multiple types of SMS integrated services, was designed and built mainly
with off-the-shelf components and open source software. The platform is highly reliable and flexible,
enabling fast provision of customisable services by integrating SMS, voice, VoIP, and web services in
innovative ways. This paper describes the design of the platform and presents four major application areas.
Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.
Cracking the Workplace Discipline Code Main.pptxWorkforce Group
Cultivating and maintaining discipline within teams is a critical differentiator for successful organisations.
Forward-thinking leaders and business managers understand the impact that discipline has on organisational success. A disciplined workforce operates with clarity, focus, and a shared understanding of expectations, ultimately driving better results, optimising productivity, and facilitating seamless collaboration.
Although discipline is not a one-size-fits-all approach, it can help create a work environment that encourages personal growth and accountability rather than solely relying on punitive measures.
In this deck, you will learn the significance of workplace discipline for organisational success. You’ll also learn
• Four (4) workplace discipline methods you should consider
• The best and most practical approach to implementing workplace discipline.
• Three (3) key tips to maintain a disciplined workplace.
Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.
