Abstract

A cellular telephone network (10) includes plural system areas (32) each having a plurality of cells (12). The system areas do not support cellular communications in all of the same hyperbands. When a verification signal strength measurement (118, 218) is needed, a message (114, 116) is sent from a first one of the system areas to a second one of the system areas, with the message including not only an identification for measurement of the traffic channel currently being used by a mobile station, but also an identification of the hyperband within which that traffic channel exists. The report (120, 122) on the results of the requested measurement and hyperband capabilities of target cell is then sent from the second system area to the first system area. From this information, the first system area may confirm (124, 224) that the measurement was made or was attempted in the proper hyperband and thus determine whether the second system would be able to support mobile station operation with respect to hyperband in the event of an inter-system hand off.
