IMS and SIP Signalling with UMTS Access - Online

IMS and SIP Signalling with UMTS Access - Online

The IMS and SIP Signalling with UMTS Access course provides a thorough and fairly detailed understanding of the architectures, functions and protocols in IMS as specified by 3GPP for the GERAN/UTRAN access. Signalling flows of relevant traffic cases for the IMS architecture are studied. Especially the SIP signalling and the SDP exchange are examined from different aspects, on overview level as well as in some depth, analysing the parameters used in the SIP messages and responses.

Network Overview

• An overview of the UMTS Core Network evolution and the protocols and addresses used
• Codecs: EFR, AMR and AMR-WB

Voice over IP – basics

• Control plane: SIP and SDP

• Basic SIP concepts and nodes
• PSTN breakout; the MGC and MGW

IMS Architecture

• How 3GPP uses SIP in IMS
• Introduction of the P-, I-, and S-CSCF nodes
• The HSS and SLF nodes and the Cx and Dx reference points
• The AS node and the Filter Criteria

• SIP URI and tel URI usage; implicit registration set and the use of Alias identities
• Usage of GRUU
• Basic SIP signalling flows: Registration and Session Initiation

SIP extensions used in IMS

• DNS usage in SIP; SRV and NAPTR records
• ENUM usage
• IMS Register and Invite signalling flows with the 3GPP extensions. A trace is presented for illustration

DIAMETER

• The Diameter base protocol
• Diameter usage on the Cx and Dx reference points

• IMS usage of IPsec ESP and IKE
• GPRS-IMS Bundled Authentication (GIBA)

Interworking

• PSTN/CS breakout; the BGCF, IMS-MGW and MGCF nodes and the H.248 protocol
• IP/PS interworking; the use of a B2BUA
• IPv6 and IPv4 interworking; the IMS-ALG and the TrGW
• The support for NAT in IMS

Charging

• Policy and Charging Control (PCC) usage for charging information transfer to the online and offline charging nodes

Quality of Service

• The UMTS end-to-end QoS approach
• Policy and Charging Control (PCC) usage for QoS handling

Services

• The IMS Service Provisioning Architecture; the SIP methods Refer and Publish. How to route on Public Service Identity (PSI)
• Multimedia Telephony Service, IMS Centralized Services and Service Continuity
• SIP usage in Presence, Push-to-Talk, Conferencing, Supplementary Services, Combinational Services and Messaging

Introduction

Launched at the Mobile World Congress in Barcelona 2010, Apis on-line training is the future of mobile technology training. You can now enjoy the full benefits of Apis’ interactive and engaging classroom methodology, whilst conducting the training on your own terms; in any location and at any time.

As a participant of our on-line training, you will first receive a comprehensive documentation set which includes our FoldOuts® which forms a basis for the engaging methodology. You thereafter log in to our easy-to-use learning portal, where you start your course. You can attend the training, in your own pace and in your own time.

Apis’ on-line training is based on videos professionally recorded in a custom designed studio. Our course methodology is mind mapping based and highly structured – just like in our classroom deliveries. Most importantly, we use real subject expert trainers to deliver the training, also in the studio.

Unlike traditional e-learning, our on-line training is engaging. It gives you the opportunity to attend Apis’ quality training with all the cost advantages and flexibility that typically is associated with e-learning. Do you not think it will work? Contact one of our sales representatives to try a demo course.

Customer Benefits

Let’s face it. Competence development continues to be extremely important to any organization that wants to stay competitive. At the same time, it is hard for staff to take several days out of work to attend training. If they have time, they may not have the budget for travel.

The on-line training enables participants to fit the training into their work schedules and between meetings so the training does not impact business critical processes. The cost for travel is removed. All in all, this results in very significant savings for both the employee and employer.

How does it work?

Our video courses are distributed on a dynamic streaming platform, which require our participants to connect to our IT platform in Sweden through the internet. The minimum bandwidth required is 80 kbps but we recommend a 150 kbps connection or better.

The service is designed for Internet Explorer browsers and requires a Flash Player version 10 (available free of charge from Adobe).

Is this e-learning?

Our on-line training is essentially great classroom training distributed through video over the internet. It has nothing in common with traditional e-learning which tends to lack pedagogical qualities, and is based on computer animations of varying quality.

However, it provides the same benefits when it comes to giving the customer the ability to do the training anywhere and anytime.

The IMS and SIP Signalling with UMTS Access training course has been designed for telecom professionals working with technical project management, product management, hardware and software design, system engineering, testing and verification, network planning, operations and maintenance and technical sales of IMS systems, products and services.
