Updating rich communication suite capability information over a communications network

A method of operating a user equipment (UE) configured to implement a rich communication suite (RCS) protocol, comprising:

• receiving an RCS capabilities request message from a requesting UE that is configured to request (i) RCS capability information for the UE, and (ii) RCS capability information for a set of one or more other UEs;
• determining that the UE has access to RCS capability information for at least one UE from the set of one or more other UEs;
• configuring an RCS capabilities response message that indicates (i) the RCS capability information for the UE and (ii) the RCS capability information for the at least one UE from the set of one or more other UEs;
• and
• transmitting the configured RCS capabilities response message to the requesting UE.

A user equipment (UE) configured to implement a rich communication suite (RCS) protocol, comprising:

• means for configuring an RCS capabilities request message to request a first target UE to provide (i) RCS capability information for the first target UE, and (ii) RCS capability information for a set of one or more other UEs;
• means for transmitting the configured RCS capabilities request message to the first target UE;
• and
• means for receiving, in response to the transmission, an RCS capabilities response message that indicates (i) the RCS capability information for the first target UE and (ii) RCS capability information for at least one UE from the set of one or more other UEs.

A user equipment (UE) configured to implement a rich communication suite (RCS) protocol, comprising:

• a processor, a memory and/or a transceiver configured to:
• configure an RCS capabilities request message to request a first target UE to provide (i) RCS capability information for the first target UE, and (ii) RCS capability information for a set of one or more other UEs;
• transmit the configured RCS capabilities request message to the first target UE;
• and
• receive, in response to the transmission, an RCS capabilities response message that indicates (i) the RCS capability information for the first target UE and (ii) RCS capability information for at least one UE from the set of one or more other UEs.

• and
• transmit the configured RCS capabilities response message to the requesting UE.

A non-transitory computer-readable medium containing instructions stored thereon, which, when executed by a user equipment (UE) configured to implement a rich communication suite (RCS) protocol, cause the UE to perform operations, the instructions comprising:

• at least one instruction configured to cause the UE to configure an RCS capabilities request message to request a first target UE to provide (i) RCS capability information for the first target UE, and (ii) RCS capability information for a set of one or more other UEs;
• at least one instruction configured to cause the UE to transmit the configured RCS capabilities request message to the first target UE;
• and
• at least one instruction configured to cause the UE to receive, in response to the transmission, an RCS capabilities response message that indicates (i) the RCS capability information for the first target UE and (ii) RCS capability information for at least one UE from the set of one or more other UEs.
