What is IMS (IP Multimedia Subsystem)?
IMS or IP Multimedia Subsystem represents a 3GPP and 3GPP2 effort to define an all IP based wireless network as compared to the historically disparate voice, data, signaling, and control network elements
Although the IMS was originally specified for 3rd generation mobile networks, it also provides an excellent service deployment architecture for any fixed or wireless network
IMS standards define open interfaces for session management, access control, mobility management, service control, and billing.
Carrier Grade Network with Lower OpEx and More Flexibility
SIP as a common signaling protocol allows independent software developers to leverage a broad range of 3rd party application servers, media servers

IMS Network Elements
Access Gateway (AG): This network element provides an interface between the radio network (Access Network) and the IP-based network.
Call Session Control Function (CSCF): Provides control and routing function for IP sessions.
Foreign Agent (FA): Advertises itself to mobile stations in serving area. Provides registration information to Home Agent. Forwards packets from mobile to Home Agent.
Home Agent (HA): Tracks current Foreign Agent serving the mobile. Forwards packets to current FA.
Home Subscriber Server (HSS): Can take the place of a HLR in all-IP network. Contains AAA function and other databases
IMS Network Elements
Media Gateway (MGW): Provides interface for bearer traffic between IP and PSTN
Media Gateway Control Function (MGCF): Provides signaling interoperability between IP and PSTN domains – SIP to ISUP and vice versa
Policy Decision Function (PDF): As IP networks, unlike TDM networks, assign network bandwidth and resources in real-time, the PDF’s role is to assign resources according to demand and QoS requirements.
Position Determining Entity (PDE): While some mobiles can determine position independently, the PDE can provide assistance by way of location determination algorithms
SIP Application Server: Represents a platform for SIP application development and operation
SBC – Session Border Controller
Requirements of an IMS platform
An open and standard architecture for easy development and portability of applications especially while IMS is still being developed and updated
A carrier-grade physical platform for reliable service delivery.
Provisions for connections to legacy network elements.
Integration with non-IMS Networks and Services
Scalability. Services should be securely deployable to thousands of customers on a single, cost-effective platform.
Robust and granular Quality of Service (QoS) per customer and/or per service. The essence of SIP-based services is their real-time and interactive nature.
Secure Participation of 3 rd Party Vendors
Network management and billing services.
