Mobile communication system and mobile communication method thereof

Claim 2

A mobile communication system as claimed in claim 1, said transmission-stop control means includes function causing one base station identification code incorporating at least "transmission-stop" instruction to generate, followed by outputting and transmitting said one base station identification code, and said transmission-stop warning means includes function causing the other base station identification code incorporating at least "transmission-stop warning" information to generate, followed by outputting and transmitting said other base station identification code.

Claim 3

A mobile communication system as claimed in claim 1, wherein said transmission-stop control means includes function causing a frame incorporating at least "transmission-stop" instruction and a base station identification code to form, followed by outputting and transmitting said frame, and wherein said transmission-stop warning means includes function causing a frame incorporating at least "transmission-stop warning" information and the base station identification code to form, followed by outputting and transmitting said frame.

Claim 4

A mobile communication system consisting of a plurality of base stations having individual service area determined respectively, and many and unspecified mobile stations implementing communication while selecting one base station of said plurality of base stations voluntarily, wherein whole service area in said mobile communication system comprises at least more than one transmission prohibition service area which is provided as a transmission prohibition zone, a plurality of transmission-stop warning service areas which are provided as first warning zones respectively arranged in contact with periphery of said transmission prohibition service area, and a plurality of outside-warning service areas which are provided as second warning zone arranged at periphery of said whole service area, said mobile communication system comprising: a transmission-stop control means for prohibiting a transmission output due to mobile station device being provided for base station of said transmission prohibition service area; a transmission-stop warning means for communicating to the user of the mobile station device that the mobile station device is approaching to the transmission-stop zone being provided for the base station of said transmission-stop warning service area; and an outside-area warning means for communicating to the user that corresponding mobile station is approaching to outside of said whole service area being provided for the base station of said outside-warning service area.

Claim 5

A mobile communication system as claimed in claim 4, wherein said transmission-stop control means includes a function causing at least a base station identification code incorporating "transmission-stop" instruction to generate, followed by outputting and transmitting said base station identification code, wherein said transmission-stop warning means includes a function causing at least an other base station identification code incorporating "transmission-stop warning" information to generate, followed by outputting, and transmitting said other base station identification code, and wherein said outside-warning means includes a function causing at least an another base station identification code incorporating "outside warning" information to generate, followed by outputting, and transmitting said another base station identification code.

Claim 6

A mobile communication system as claimed in claim 4, wherein said transmission-stop control means includes a function causing at least a frame incorporating "transmission-stop" instruction and a base station identification code to form, followed by outputting, and transmitting said frame, wherein said transmission-stop warning means includes a function causing at least a frame incorporating "transmission-stop warning" information and a base station identification code to form, followed by outputting, and transmitting said frame, and wherein said outside warning means includes a function causing at least a frame incorporating "outside warning" information and a base station identification code to form, followed by outputting, and transmitting said frame.

Claim 7

A mobile communication method for communicating between many and unspecified mobile stations or between the mobile station and a public telephone network through a plurality of base stations having individual service area determined respectively wherein a transmission starting procedure is implemented before starting transmission while selecting transmission destination, or before starting transmission at the time hand over selecting transmission destination base station, as said transmission starting procedure comprising the steps of: a first step for retrieving frequency of signal transmitted to be outputted from all base stations within whole service area in said mobile communication system, thus receiving a base station identification code of respective base stations which are capable of being recognized due to the retrieval; a second stop for judging whether or not there exists a base station identification code including "transmission-stop" instruction as a transmission control instruction among the received base station identification codes though it is only one "transmission-stop" instruction; a third step for judging that present location of mobile station is not a established transmission-stop zone which transmission output is being prohibited, when there does not exist the base station identification code incorporating "transmission-stop" instruction as a transmission control instruction in said second step; a fourth step for returning to reception operation state, namely returning to said first step while stopping transmission output, after judging that present location of the mobile station is located within the zone being established as the transmission-stop zone, when there exists the base station identification code incorporating "transmission-stop" as the transmission control instruction in said second step; a fifth step for selecting a transmission destination base station following said third step; a sixth step for judging whether or not warning information is incorporated into a base station identification code of the transmission destination base station selected in said fifth step; a seventh step for starting transmission to the transmission destination base station while shifting to normal operation when there is judged that warning information is not incorporated in base station identification code of the transmission destination base station in said sixth step; and a eighth step for starting transmission to said transmission destination base station while shifting to normal operation of said seventh step corresponding to a warning content after indicating warning information to user when warning information is incorporated in the base station identification code of the transmission destination base station in said sixth step.

Claim 8

A mobile communication method as claimed in claim 7, wherein said warning information which is taken as candidate of judgement in said fifth step is "transmission-stop warning" information informs that location of the mobile station is approaching to transmission prohibition zone.

Claim 9

A mobile communication method as claimed in claim 7, wherein said warning information which is taken as candidate of judgement in said fifth step is "outside-area warning" information informs that location of the mobile station is approaching to outside-area of whole service area.
