ABI Research: IMS Finding a New Home with LTE

IMS (IP Multimedia Subsystems) has been around for some time, and many infrastructure vendors have invested heavily in developing IMS capabilities, solutions and products. But market acceptance has been slower than expected. Now, with the 4G standards LTE (Long Term Evolution) and WiMAX taking shape, the IMS platform has been given a new role and a niche that will carry it a considerable distance into the future.

 

That is because some elements of IMS such as the Home Subscriber Server (HSS) and the Policy and Charging Rule Function (PCRF) are also key components in the LTE core architecture. Similar elements are also defined in WiMAX. These elements are required to enable the end-to-end QoS and dynamic charging capabilities required for the next generation of mobile data services.
