Temporary address system in a radio communication system

A radio system using a temporary address system comprising:

• frame for transmitting a stored digital code data by radio of a plurality of frequencies or a plurality of frequency groups, said frame including a bit and frame sync field, frame count field, address field, control field, transmission data field, and frame check and correct sequence field;
• and
• zones each formed of a radio base station forming an area to/from which said digital code data stored in said frame means can be transmitted/received, and at least one portable radio terminal device for conducting transmission and reception of a signal with respect to said radio base station in said area, a frequency group is assigned to each of the zones,
• wherein said zones are made into a group in which areas of frequencies are arranged such that areas of the same frequency group are not located adjacent to each other, and
• said radio base station registers a temporary address for a terminal device every time a radio link is set upon either transmission request from a terminal device, or reception request from the radio base station, and erase the temporary address after completion of communications.

A temporary address system in a radio communication system, comprising:

• a plurality of zones, each of which has at least one radio terminal device in an area of a radio base station for transmitting/receiving a signal, said plurality of zones being grouped such that areas of a same frequency are not arranged adjacent with each other, thereby the same frequency is repeatedly used;
• and
• an address field which stores identification data of a radio base station and radio terminal device, said address field being located in a frame for transmitting digital code data by radio;
• and wherein
• data based on the number of zone groups is assigned to said address field as the identification data of the radio base station.

• an address field which stores identification data of a radio base station and radio terminal device, said address field being located in a frame for transmitting digital code data by radio;
• and wherein
• temporary identification data of a radio terminal device, which is effective only when a radio link is constituted between the radio base station and the radio terminal device, is assigned to said address field as the identification data of the radio terminal device.
