Embodiment Construction

[0029] Reference will now be made in detail to some embodiments of the invention, some examples of which are illustrated in the accompanying drawings.

[0030] figure 1is a schematic diagram of the top layer signaling flow for UL shaping in RRC idle mode according to a novel aspect. In step 111 , UE101 establishes camping on a cell in network 102 . UE 101 is in RRC idle mode. In step 112, the UE 101 receives the packet to be transmitted to the network. In the existing system, after the UL packet arrives, the UE can enter RRC connected mode and perform UL transmission. However, when the traffic is delay tolerant and the packet size is small, it is not efficient to do the transmission immediately, because most UEs stay in RRC idle mode and need to re-establish the RRC connection. Frequent RRC connection-idle state transitions result in significant signaling and quality reductions in power saving performance.

[0031] According to a novel aspect, in step 113, UE 101 perform...

Abstract

A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.
