GSMA launches RCS Specification Release 2

GSMA, who represents the interests of the cellular industry, announced today the launch of the next set of service specifications, RCS Release 2, for the RCS Initiative (Rich Communication Suite) and also the RCS DevChallenge, a new contest for client applications developers for mobile phones and PCs.

The contest is sponsored by Alcatel-Lucent, Ericsson, Nokia Siemens Networks, Orange and Telefonica. For more information and register, please visit this site:
http://www.rcsdevchallenge.com.

"As an active member of GSMA RCS Initiative, Alcatel-Lucent is helping service providers to leverage the RCS Specification Release 2 to successfully meet the consumers demands for a new generation of continuous and improved services, transcending the devices and areas of the fixed and mobile telephony over Internet", said Gani Nayak, Chairman of the Division of Interactive Media and Communications Applications at Alcatel-Lucent.

"Ericsson welcomes you to the launch of RCS Specification Release 2 that allows service providers to offer a common experience of multimedia communication for mobile phones and other devices connected to broadband", said Magnus Furustam, Vice-President of Product Area Core and IMS at Ericsson. "Our RCS activities are concentrated in the implementation of a interoperable platform with complete communication, to unify the billions of telecommunications subscribers through some common standards. The open and inclusive nature of RCS provides an ideal platform for the innovation of the developers, and therefore we are delighted to sponsor the RCS DevChallenge".

It's always good to know that we have such events encouraging the creativity and the work of developers for this market. And I hope we have more investment in the Brazilian market, as we are far behind the world powers.

Installing Ericsson SDS

The SDS (Service Development Studio), is a Ericsson's tool development of IMS (IP Multimedia Subsystem) aplications. Today will post a SDS installation tutorial.
System Requirements:

• Java 5 Download (SDS does not work with Java 6!)
  
• Windows XP SP2 (SDS does not work in Windows Vista!)
• 1GB of RAM (512MB work, but .... )
• WTK (Wireless Toolkit)

At the beginning, a license is needed for instalation. If you don't have it, register and ensure if for free! After this, select all components to install and place them where the Java 5 is istalled and where SDS will be installed.

After SDS installation, UIQ 3 installer will start (standart installation: nest, nest, finish). Then, Nokia compiler installer will start, again a standart installation. After WinPcap 3.1 installation, you will NOT restart, selecting the option "No, I'll reboot later" and press Next. Finalize the installation of UIQ 3 and then P1 SDK (Sony Ericsson) installation starts.

After that starts the installation of SailFin, it will be the Web Server for IMS Aplications. You can download Sailfin (Windows), save the file in C:\

Set the enviroment variables, JAVA_HOME. Run the Command Prompt and type java -Xmx256m -jar
Accept the license and enter the created directory C:\SailFin and type lib\ant\bin\ant -f setup.xml
After the "BUILD SUCCESSFUL" message appears you can close the Command Prompt and complete the installation of the SDS. Restart the computer. You now have SDS installed on your computer.

You can check the complete tutorial on IMS Technology Group. Download the complete installation manual and a video tutorial with full installation here.

Control Layer - Part 1 (HSS)

After writing about the IMS technology architecture, we will analyze more deeply the control layer . As seen, in this layer is responsible to make the connection between devices and services, abstracting the used network.

Today, we write about the HSS (Home Subscriber Server)
HSS is like a devices' central database of IMS network, it's responsible for the authentication information, authorization and physical location. It stores the users profiles and their services, independently of the service provider.

HSS is an evolution of the HLR (Home Location Register), which is a node specified by the GSM architecture.

According to the 3GPP specification, HSS provides the establishment of calls and / or meetings, creation of security information devices and identification and authorization to access them. It interacts with CSCF (Call Session Control Function) through Diameter protocol.

Venturus presents IMS application

Venturus company has created a virtual contest of penalties with using IMS technology (IP Multimedia Subsystem). To illustrate and bring the technology closer to IMS users, Venturus chose to show a simulation on a TV program, based in a game with interaction with the remote viewers, via cellphone. The simulation uses the IMS platform to enable communication between the TV, notebooks and cellphones, through features and specific protocols. Thus, the players can see themselves on TV during the program. They are virtually represented by the photos you send by the cellphone.

Venturus has been developing applications on top of IMS technology for some time now. Futurecom In 2007, the Institute presented to the public an example of use of technology to transmit, by phone, pictures of the event in real time.

IMS Layers

Well, after a brief explanation of concepts IMS about IMS Concepts (IP Multimedia Subsystem), now we show how things work. Basically, the IMS architecture is based on 3 layers: Transport, Control and Services.

Transport: This layer is responsible for converging converge all networks (wireless, GSM, GPRS, 3G, fixed telephony, among others) in networks based on IP, because IMS is based on networks that use the TCP / IP protocols.

This layer is intended to disregard the manner of how the data will be transported, no matter which network we're using, but how to use it, as it should be used in a much simpler and more standardized.

Control: Layer responsible for communication between devices and services. She It performs the authentication and controls traffic between the layers of network and services. It can also facilitate communication between services.

As this layer is all based on IP, it is able to combine data, voice and video in a single only one session.

Services: The most important layer because here the focus is on services that are available to users, we do not care how they come to the devices or other network, because it was oblivious to the abstracted by network and control layers. This causes makes that the IMS architecture has have flexibility to implement new services.

This makes the IMS architecture a reality for digital convergence and ready for the availability of services, able to be discovered and reused.
