context: An UE establishes a RCS File Transfer service per GSMA RCC.07 [504] towards another UE, while roaming in a VPLMN with traffic broken out from the Visited Network. UE RCS device is assumed to be configured for VoLTE, and the home network is assumed to support use of IMS APN. Per GSMA RCC.07 [504], the following apply in consequence: - Per clause 2.9.1.4: â¢ "All services on a device configured for VoLTE, whether it is in RCS-VoLTE mode or in RCS-CS mode, shall follow the general rules as per IR.88] [501], APN usage as per IR.92 [502]" â¢ "When the device and the home network support the use of the IMS APN, the IMS APN shall be used to access the RCS services". - Per clause 2.9.1.3 (assuming RCS device configured for VoLTE): For all IMS traffic the following applies for an RCS device configured for VoLTE/VoHSPA: â¢ "APN usage shall be according to [PRD-IR.92]". â¢ "For LTE bearer management see section 4.3 of [PRD-IR.92] ". For all RCS IMS traffic the following applies: â¢ "For a device in
description: RCS (Rich Communication Services) is a service that enables advanced communication features such as file transfer, voice and video calls, and messaging. It is designed to provide a richer communication experience for users.
explanation: The text explicitly refers to RCS as a 'service' that offers functionalities like file transfer, voice/video calls, and messaging. This aligns with the definition of a telecommunications service.
