Embodiment Construction

[0023] Some embodiments of the present invention will now be introduced in detail, and these examples will be described in conjunction with the accompanying drawings.

[0024] The 3GPP LTE system has been designed to provide significantly higher data rates, higher system throughput, and lower latency for delay critical services. One of the main purposes of LTE, or any wireless system, is to provide fast and seamless handover from one cell (source cell) to another cell (target cell). The impact of the LTE handover process on the overall user experience is important to the overall system performance. There is a need to provide and guarantee improved handover performance under various mobility conditions, including intra-RAT handover as well as cross-RAT handover.

[0025] figure 1 is an example flowchart of an improved handover procedure for intra-RAT handover. In step 101, the UE performs a signaling procedure. The various signaling procedures during operation are of diffe...

Abstract

Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established.
