In particular, the improved telecommunications network may include an improved RCS server that can route secure multicast messages instead of and/or in addition to unicast messages. For example, the improved RCS server can create a multicast group for a group of UEs in response to a request from a UE to create a group of UEs. Creation of the multicast group may include creating a shared multicast group key (SMGK) for the multicast group and/or selecting a security algorithm for the multicast group. The improved RCS server can then distribute the SMGK and/or the selected security algorithm to the UEs such that the UEs can use the SMGK and/or the selected security algorithm to encrypt and/or decrypt messages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure rich communication services multicast system","description":"An improved telecommunications network that can reduce the network load on a rich communication services (RCS) server and/or local routers that implement 1-to-N and/or M-to-N services is described her","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11297494","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
