ENHANCEMENT PROCEDURE OF SUSPENDING AND RESUMING UE DATA IN MOBILE COMMUNICATION NETWORKS

摘要

A method for UE to indicate its upcoming transceiver operation status to network and help network to avoid inefficient radio resource schedule for better network efficiency is proposed. The proposed method also helps network to manage the connections for user applications to prevent unnecessary disruption due to short-term radio link disconnection. In one embodiment, the UE is a dual SIM dual standby (DSDS) UE. The UE first establishes an RRC connection and starts data transmission. Upon detecting a suspension event, the UE sends a signaling connection release indication (SCRI) with a new cause for “UE requested PS data suspension”. The SCRI may further include a suspension reason and a suspension period. When the network receives the SCRI, it will interpret that the UE may not be able to receive its downlink signal during the upcoming period and may prevent schedule radio resource for the UE.
