Abstract
One of the most important things is Hand-0ff(H/O) in mobile phone service. Meantime soft H/O and softer H/O have been used between the same generations(2G$\longleftrightarrow$2G) and there is little problem. With user's needs and the development of communication technology, the system with different generation coexists and pilot beacon and time-periodic beacon are used for H/O between generations(2.5G$\longleftrightarrow$G) to start service, but it is not economic and efficient. To improve such problems, ENHHO developed in April 2001 has recently used. Unfortunately, this method also has the defect of momentary cutoff of communication information during the procedure of H/O in case of mote than 5 pilot signals. Accordingly, we suggest algorithm to improve the problem of ENHHO and examines its propriety by analyzing the results of field survey using the algorithm.
