TLDR
In this article, a peer-to-peer communication system for IP multimedia subsystem (IMS) functionality is described, where each peer user equipment includes an IMS server, and the peer-peer communications is established independent of network-based IMS servers.
Abstract
Systems and methods for peer-to-peer communication between user equipment using IP multimedia subsystem (IMS) functionality are provided. Each peer user equipment includes an IMS server and the peer-to-peer communication is established independent of network-based IMS servers. A third user equipment that does not include an IMS server can join the peer-to-peer communication using network-based IMS servers.

System and method for visiting subscriber server in ims core networks

TL;DR: In this article, the authors propose a method for supporting an inbound roaming subscriber in an IMS network, which consists of receiving a request from the roaming subscriber to access the IMS networks, determining the roaming user's home network, retrieving authentication credentials from the home network and verifying the authentication credentials, dynamically deriving public and private user identities for the in-bound roaming user, and creating and storing a subscriber record for the roaming customer.
