PORTABLE RADIO TELEPHONE AND OPERATING METHOD THEREFOR

Japanese Patent JPH08251650

A

PROBLEM TO BE SOLVED: To provide a portable radio telephone which uses a dynamic channel designation algorithm that gives very healthy performance. SOLUTION: A portable radio telephone 5 communicates with base stations 1 and 2 in a digital radio telephone system such as a DECT that uses TDMA transmission. The portable radio telephone is programmed with an algorithm that operates to select a communication channel by storing a blind slot mask 7 representing the time slot of each frame which is excluded when a base station occupies it or when the portable radio telephone itself occupies it. Then, a channel which was tried in an occupied time slot and failed is excluded and it is marked as blind in the blind slot mask. Further, the algorithm checks the availability of a time slot in a temporary sequence of the slot or on the contrary, in a corresponding prescribed sequence and operates to encourage orderly filling of time slots in a base station.
