Abstract

Abstract According to a method of arranging radio control channels in mobile communications, for covering a service area with a plurality of radio zones and causing base and mobile stations to exchange signals through the control channels, a broadcasting information transmission portion is assigned to the control channels. This broadcasting information is to be transmitted from the base station to each mobile station to broadcast information associated with radio zones. Information associated with control channel structure in units of base stations is broadcast to the broadcasting information transmission portion. A frequency and a time slot capable of causing the base station and the each mobile station to exchange the signals are determined on the basis of the pieces of broadcasting information and an identical number commonly recognized by the base and mobile stations.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 130 words
A method of arranging radio control channels in mobile communications, for covering a service area with a plurality of radio zones and causing base and mobile stations to exchange signals through the control channels, comprising the steps of: assigning a broadcasting information transmission portion to the control channels, the broadcasting information being transmitted from said base station to each mobile station to broadcast information associated with radio zones; broadcasting information associated with control channel structure in units of base stations to said broadcasting information transmission portion; and determining a frequency and a time slot capable of causing said base station and said each mobile station to exchange the signals on the basis of the pieces of broadcasting information and an identical number commonly recognized by said base and mobile stations.
Claim 2
Independent Claim 130 words
A method of arranging radio control channels in mobile communications, for covering a service area with a plurality of radio zones and causing base and mobile stations to exchange signals through the control channels, comprising the steps of: assigning a broadcasting information transmission portion to the control channels, the broadcasting information being transmitted from said base station to each mobile station to broadcast information associated with radio zones; broadcasting information associated with control channel structure in units of base stations to said broadcasting information transmission portion; and determining a frequency and a time slot capable of causing said base station and said each mobile station to exchange the signals on the basis of the pieces of broadcasting information and an identical number commonly recognized by said base and mobile stations.
Claim 3
Dependent Claim 33 words
A method accordihg to claim 1, wherein the pieces of information associated with the control channel structure and to be broadcast in said broadcasting information transmission portion are identical in all base stations.
Claim 4
Dependent Claim 33 words
A method according to claim 1, wherein the pieces of information associated with the control channel structure and to be broadcast in said broadcasting information transmission portion are different in all base stations.
Claim 5
Dependent Claim 79 words
A method according to claim 1, wherein a given one of said mobile stations determines a paging signal transmission portion classified to be received by said given mobile station, said base station has a function of transmitting a paging signal for said given mobile station to said paging signal transmission portion classified to be received by said given mobile station, and said given mobile station receives only the paging portion classified to be received by said given mobile station.
Claim 6
Dependent Claim 66 words
A method according to claim 4, wherein said given mobile station has a function of receiving other control channels by portions except for said paging signal transmission portion classified to be received by said given mobile station, and said given mobile station monitors radio channels of said other radio zones by said portions except for said paging portion classified to be received by said paging station.
