There is currently no accepted standard for the measurement or monitoring of RCS Services. Ascom has created a formal definition and implementation strategy to help the Operations Team with issues related to EPC, IMS and Application Servers. We will describe this solution in a number of short articles.

4. RCS Monitoring - 24 x 7
IMS Solution 2.7 for VoLTE, VoWiFi, RCS and VoB
Our RCS Monitoring Solution consists of a suite of test cases (described on the
next slide), which is run to provide 24 x 7 monitoring of service availability and
additional diagnostics to investigate outages or other issues.
Test cases are run on a high-availability, multiply-redundant Cloud-based system
with a 99.95% uptime guarantee, to maintain 24 x 7 operation.
Results are published in near-real-time to dashboards on a web portal with the
same uptime guarantee and can be accessed from any compatible web browser.
Confidentiality is protected by physical security for the servers and user
authentication for remote access; encrypted protocols and client IP whitelisting
are also available to further secure remote access.
The RCS Monitoring Solution monitors:
 the entire set of RCS Services defined by the GSMA specs for RCS-e v1.2.2
 the File Transfer over HTTP Service as defined in RCS release 5 onwards
 the supporting procedures which these services require to run
