ENHANCED TUNE-AWAY MECHANISM DURING SIGNALING PROCEDURE IN MULTIPLE SUBSCRIPTION COMMUNICATIONS

摘要

In various aspects of the disclosure, an improved tune-away technique is utilized by a user equipment (UE) for wireless communication during a signaling procedure for a primary subscription with reduced impact on paging performance of one or more secondary subscriptions. The UE performs a signaling procedure including receiving at least one protocol data unit (PDU) of a signaling radio bearer (SRB) message from a first network associated with the first subscription. The UE further determines a message type of the SRB message based on the at least one received PDU. If the message type indicates that the SRB message includes a signaling non-critical message, the UE further performs a tune-away procedure to communicate with a second network associated with the second subscription, while the signaling procedure is ongoing.
