Abstract Research purposes: Many problems about handover exist in the passenger dedicated railway and subway mobile communication. The research was made on the scheme of totaling the cross-zone handover. It was proposed for the purpose of providing basis and reference to the wireless communication planning and opitimizing for railway and subway mobile communication. Research methods: In accordance with the analysis of different schemes on totaling the cross-zone handover and in combination with the technology development of railway mobile communication system, the comparison and research were made for some programs from the economy and feasibility and dependability for urban transit. Research results: Several schemes on totaling the cross-zone handover were presented and comparied. Research conclusions: In the working of locating the cross-zone handover, not only the speed and the time of handover would be considered, but also the fast fading and the mechanism of handover would be considered.
