Section: 5.38.4 Reject Paging Request
Content: A Multi-USIM UE may set up a connection to respond to a page with a Reject Paging Indication to the network indicating that the UE does not accept the paging and requests to return to CM-IDLE state after sending this response, if both UE and network indicate the Reject Paging Request feature is supported to each other. Upon being paged by the network, the Multi-USIM UE in CM-IDLE state attempts to send a Service Request message to the paging network including the Reject Paging Indication as the response to the paging, unless it is unable to do so, e.g. due to UE implementation constraints. In addition to the Reject Paging Indication, the UE may include Paging Restriction Information as specified in clause 5.38.5 in the Service Request message, if supported by UE and network. NOTE: A Multi-USIM UE in RRC_INACTIVE state can decide to not initiate the RRC connection resumption procedure, e.g. when it decides not to respond to the paging message due to UE implementation constraints as specified in TS 24.501[ Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3 ]  [47] and TS 38.331[ NR; Radio Resource Control (RRC); Protocol specification ]  [28].
