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:

Ericsson has released a new version of SDS. SDS 4.1 has a few changes, highlighting some of them:
On June 6th I instructed a mini course in Metodista about IMS and SDS. In this event participated students from the graduation courses of "computer engineering" and "information systems" that are in the penultimate semester and developing their IMS projects.
Were considered the concepts of IMS technology, such as architecture, SIP, CSCF and HSS. We also talked about SDS, which is the Ericsson IDE for development of IMS applications.

Ericsson and TeliaSonera announced the signing of a commercial 4G network, this network will cover Sweden's capital Stockholm and the contract is Ericsson's first for commercial deployment of LTE. Ericsson and TeliaSonera have started the roll-out in Stockholm, for commercial launch 2010.
We already talked about HSS, now is time to describe other component. The CSCF (Call Session Control Function) is a SIP server and it's responsable for the first iterations int the IMS network. It has the function of registration the termination and establishment of sessions. The CSCF server is divided on 3 parts: S-CSCF (Serving), I-CSCF (Interrogating) and P-CSCF (Proxy).

In coming posts we will go into detail on each part of the server CSCF.
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:
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.
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.
As it was posted, Ericsson launches IPTV with IMS technology. Here's a video about the launching of the first IPTV middleware integrated with IMS. Ericsson is developing a TV plataform that will allow the television industry to fulfill the vision of the individualization of the experience of watching television.
Ericsson’s SDS (Service Development Studio) is a development tool for IMS (IP Multimedia Subsystem) applications and is part of Ericsson Mobility World. It has a standard IMS-based network with communication services simulator and the client side includes devices for mobile, fixed broadband and WLAN access. The SDS is on version 4.1, which contains the new following features:
* Support for Nokia S60 phones and C + + APIs
* Integration with the SailFin 1.0 JavaEE / SIP server
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.
As we have seen, IMS is a platform that allows various devices to communicate to independently of the network.
A very interesting video on the subject can be seen below.
In the video are demonstrated how we can use technology to facilitate our lives. We see for example, the provision of a mobile device with an IPTV, both in the exchange of messages and the sharing of videos.
Ericsson's presentation about IMS platform (IP Multimedia Subsystem).
Ericsson shows how IMS can help operators to improve their profits, how users take advantage of this technology and how IMS is a future technology!
