What is the IP multimedia subsystem?

IP subsystem of the multimedia subsystem, also known as IMS, is architecture for multimedia delivery. Originally designed for mobile phones, multimedia sessions can be allowed between fixed or wireless telecommunications devices. It also uses the internet protocol infrastructure (IP) to transport multimedia data to the AZ connected devices. Services can use IMS to allow video teleconference, send messages, and web views for all your subscribers. It can also be used to provide multiple user games, voice over IP (VoIP) and video streaming.

In 1999, the telecommunications industry called 3G.IP was created the first specification of IP multimedia subsystems. Later, it was adopted by a third -generation partnership project (3G) as part of a 3G wireless phone standard. Its aim was to provide Internet services through General Packet Radio Service (GPRS). Several functions have been added toIMS and published in the 3G Partnership Project (3GPP) during the year 2000. It was a centralization of services, connecting to a fixed broadband device and Non-GPR support. It offers a common and repeatedly usable platform for efficient development with open standards. It can also maintain a network bandwidth to provide high quality services. Providers can use IMS to provide and billing for distributed interactive applications and services in real time. At the same time, users can benefit from trouble -free text, voice and video regardless of their location or used device.

Complex multimedia enabled IMS may require several sessions of multiple applications to be active at once. The IP multimedia subsystem subsystem manages them with protocol (SIP) and other Internet protocols. Controlling connections, sessions and services with common internet protocols simplify signaling andSoftware development. It also increases compatibility and cooperation, as all providers use the proven standard communication spine.

To facilitate smooth interaction of many types of applications and devices, the IP multimedia subsystem subsystem is divided into three layers. The transport layer processes all communications with devices such as computers, 3G phones and personal digital assistants (PDA). It also breaks with SIP mobile phones and old wire lines phones and consists of packets of analog and digital data as needed. The session and signaling is also carried out by this layer.

The

control layer of the IP multimedia subsystem subsystem manages the movement of packets between the transport layer and the application layer. It also manages calls, services for services and all user profiles. The presence server, critical for push-to-talk and other services, is also in the control layer. Applica layer insulates application servers from user devices and control problems witha mter. Many servers are supported in this layer, allowing IMS to process several types of applications and users at the same time.
