US13-8 As a developer, I want to be able to integrate RCS communications features
within my apps through APIs. This enables end users to establish a
communication from their app. Here are different scenarios according to
developers needs
R13-8-1 App to app communication: The A party triggers an RCS communication from
an app using the APIs. In this mode, A party and B party Shall both have the
same Feature Tag: B party receives the RCS communication within this app
(identified by the Feature Tag)
Figure 8: App communication
R13-8-2 App to RCS UX: The A party triggers an RCS communication from an app
using the APIs. In this second mode, B party is not required to have a specific
app or service (identified by its Feature Tag) from where the com has been
generated: the B party receives the RCS communication in his native RCS
app. The B Party can reply to A from his native UI and the A party receives it
on app and continues the conversation thread.
