摘要

This paper investigates the performance analysis and impact for the improved time-slot re-allocation scheme during the inter-frequency or inter-RAT handover from 1.28 Mcps TDD mode. Two proposed structures describe the use of asymmetric time-slot allocation pattern and the combination of different time-slot allocation pattern of traffic channel. Each proposed scheme can be applied to the measurement procedure for the possible handover scenarios to GSM and 1.28 Mcps TDD mode using different frequency band from original 1.28 Mcps TDD mode, respectively. Simulation results show that the proposed structures attain the longer measurement time for target system to enhance the reliability of measurement or increase the probability of successful synchronization for handover. In summary, the improvement of handover performance can be achieved by adopting proposed schemes, but the impacts to other system functions should be further considered to implement in a real environment.
