Abstract :
In the hierarchical cellular system, the take-back procedure usually takes place when the overflowed slow or fast call crosses the microcell boundary. In this paper, three new take-back schemes, micro-macro, macro-micro and macro-macro, based on cell boundary crossing are proposed. In terms of call blocking probability and call dropping probability, the comparison shows that micro-macro outperforms the other schemes.
