To solve the cost problem of micro/picocell system, the fiber-optic cellular system was proposed. In this system, all channel elements are managed in Central Station, not in each base station. In this paper, we propose and analyze a new intergroup handoff in the fiber-optic cellular system. The proposed scheme supports handoff with keeping current channel. Performance is evaluated in view of blocking and handoff refused probability. The numerical results show that the proposed scheme provides better performance than conventional soft handoff scheme.
