Reti TradizionaliSignaling System #7

n the early '60s, the signaling between the devices was done primarily through telephone tones sent within the voice channel (in-band). In that same period, it was realized that this method results in substantial limitations to what were the needs of the time, it was decided to develop new standards and new network architectures to make up for those shortcomings. Thus was born the Signaling System # 7 (SS7) and the structure of intelligent network (IN, English Intelligent Network). This architecture introduces major improvements, including out of band signaling, the possibility of integrating simple database within the network, centralizing some configurations deliver more advanced options than those available at that time, as the translation of phone numbers and send the caller . Today, virtually every telephone network, fixed or mobile, using the standard just described. However, things change, and the 60's also our communication needs have evolved. The SS7 system was designed for the transmission of voice and data. For the transmission of additional multimedia content was created on SIP, a signaling system that operates in the recent IP networks. Just the SIP (properly adjusted) was chosen as the basic protocol for next-generation networks that will replace the traditional ones: the IMS (IP Multimedia Subsystem). The change is beginning in these years, and will be neither simple nor immediate. In the coming years we will see the two systems side by side, in an attempt to co-exist for all the steps necessary to secure a change of technology. For this reason, the architecture based on SS7 are still heavily present in the scenario of Telecommunications, and an indispensable background to many of the providers working in this field. Report has the experience and knowledge to develop and maintain architecture type to facilitate their supplement it with the IMS / SIP and to develop advanced services for both scenarios. Above all, Comunica has the tools to advise you on technical strategies and scenarios to be taken in the development of your telecommunications networks, according to your needs!
