A method and apparatus for switching between a public macrocellular telephone system and a private microcellular telephone system is described. A mobile telephone switches between a macrocell and at least one neighbor microcell. Circuitry in the telephone monitors the signal quality of signals from the macrocell (118) and the neighbor microcells (112, 115, 116). Reselection circuitry reselects the telephone from a current microcell to the neighbor macrocell based upon a preferred neighbor status of the microcell. The reselection is based, at least in part, upon the signal quality associated with the macrocell exceeding the signal quality associated with the current microcell by a nonzero offset. The reselection may also be based, at least in part, upon the signal quality associated with the current microcell falling below a predetermined threshold. Further reselection may additionally be based upon the signal quality associated with the macrocell exceeding the predetermined threshold. Reselection from a current macrocell to a neighbor microcell may be based, at least in part, upon the signal quality associated with the neighbor microcell and a predetermined threshold. In that case, reselection may be based upon the microcell signal quality exceeding the predetermined threshold. For reselection from a current microcell to a neighbor microcell, the reselection may be based upon a regular neighbor status of the current microcell. Such reselection may occur if the signal quality associated with the neighbor microcell exceeds the signal quality associated with the current microcell by a nonzero offset. |
