This document discusses enabling Rich Communication Services (RCS) delivery. It describes how RCS can simplify IMS complexity and address challenges in making the business case for RCS. Key features of RCS include streamlining access and session management, as well as load balancing. The document also covers other pieces of the RCS service delivery puzzle like signaling control, interconnect, and summarizes that RCS is integral to the all-IP evolution.

5. Signaling control for RCS:
protecting service availability
Goals:
Assures RCS-e application servers process legitimate
subscribers
Protects servers from DoS attacks, mis-configured or
misbehaving clients and non-malicious overload
events
Requirements
Granular security per service & application
User definable
Key features
Signaling rate limiting
Access control lists and SIP Methods whitelists/
blacklists
Topology hiding
Signaling screening = Signaling DPI
Encryption: extending RCS to WiFi/Internet
