In the view of NGN – Next Generation Network, from the outset, the goal of integration and convergence of services was seen on the IP network. Accordingly, a new concept called IMS – IP Multimedia Subsystem was created by 3GPP.
In this standard, IP-based services are provided to subscribers by the IMS infrastructure that is located on the Core Network Operator or FCP. The service on the subscriber side can be convergent services. For example, data services, telephone, video, mobile, etc. will be handed over to subscribers with unit management. In this form, all services can be provide on an infrastructure and there is no need to provide different switches for different services so CAPEX and OPEX costs will decrease .In the near future and more generalization of the IOT and service of IMS in this area, the creation of new businesses in the ICT industry is provided.
The Nasim Telecom offers IMS and Online Charging in the VNF structure for Prevention from Dependency to Complex Equipment’s and for easier development and Reliability.
Due to the standard deployment capability, such as USSD over IMS, RCS and etc. There is the ability to create new requirements on the client side, and these requirements are developed by the developers of the system.
One of the most important strengths of the Nasim Telecom is the Application Server (AS), which services such as Call Forwarding, RBT or any Value Added Service (VAS) depend on the Application Server.
