UPDATING RICH COMMUNICATION SUITE CAPABILITY INFORMATION OVER A COMMUNICATIONS NETWORK

摘要

In an embodiment, a requesting UE configures an RCS capabilities request message to request a target UE to provide RCS capability information (i) for the target UE, and (ii) for a set of other UEs. The requesting UE transmits the configured RCS capabilities request message to the target UE. The target UE determines that the target UE has access to RCS capability information for at least one UE from the set of other UEs, and configures an RCS capabilities response message that indicates the RCS capability information (i) for the target UE and (ii) for the at least one UE. The target UE transmits the configured RCS capabilities response message to the requesting UE. In another embodiment, a given UE determines whether to perform an RCS capability information refresh operation based on whether RCS capability information for another UE is older than a priority-specific age threshold.

1. A method of operating a user equipment (UE) configured to implement a rich communication suite (RCS) protocol, comprising:
obtaining RCS capability information for a target UE along with an indication of a time when the RCS capability information was validated by the target UE; determining a priority associated with the target UE; identifying an RCS capability information age threshold based on the determined priority; determining whether the time indication is older than the RCS capability information age threshold; and selectively triggering an RCS capability information refresh operation with the target UE based on whether the RCS capability information for the target UE is determined to be older than the RCS capability information age threshold.
