Section: 4.3.33.4 Reject Paging Request
Content: A Multi-USIM UE may respond to a page for a USIM with an indication to the MME that the UE does not accept the paging and requests to be released to ECM-IDLE state after sending this response, if both UE and network indicate to each other the Reject Paging Request feature is supported. Upon being paged, the Multi-USIM UE attempts to send an Extended 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 4.3.33.6 in the Extended Service Request message, if the Paging Restrictions are supported by UE and network.
