Abstract
Abstract A system which transmits a calling signal to radio sections to selectively call a radio receiver. The number of times of transmission of the calling signal from a base station is variable, so that the facility of the base station can be built at a relatively low cost even when the number of subscribers per service area is small. <MATH>

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
61 words
Mobile communications system characterised in that: in a mobile communications system which has a transmitting means which transmits paging signals a plurality of times through the air by radio waves, said paging signals serving to selectively page radio receivers: there is provided a means which variably sets the number of times that paging signals are transmitted from the aforementioned transmitting means.
Claim 2
Dependent Claim
31 words
Mobile communications system as set forth in Claim 1, wherein the aforementioned transmitting means includes a means which transmits information relating to the number of times that paging signals are transmitted.
Claim 3
Dependent Claim
56 words
Mobile communications system as set forth in Claim 2, wherein the aforementioned transmitting means includes: a means which transmits in units of frames, said frames comprising one or more paging signals to which a control signal has been added, and a means which inserts, in the aforementioned control signal, information relating to the number of transmissions.
Claim 4
Dependent Claim
108 words
Mobile communications system as set forth in Claim 3, wherein: there is provided a means which forms n subframes within a frame when the number of transmissions is n ; and this means includes: a means which inserts a new paging signal in a subframe positioned at one end of said frame, and which inserts a paging signal that is to be transmitted for the second or subsequent time in a subframe arranged at a position corresponding to this number of times; and a means which changes the number and length of subframes within a frame when the aforementioned setting means changes the number of transmissions n .
Claim 5
Dependent Claim
45 words
Radio receiver characterised in that, in a radio receiver which receives paging signals from the transmitting means in a mobile communications system as set forth in Claim 1, there is provided a means which variably sets the number of times that paging signals are received.
Claim 6
Dependent Claim
72 words
Radio receiver characterised in that: in a radio receiver which receives paging signals from the transmitting means in a mobile communications system as set forth in Claims 2 or 3, there is provided: a means which receives, from the aforementioned transmitting means, information relating to the number of transmissions; and a means which, on the basis of the aforementioned received information, sets the number of times that paging signals will be received.
Claim 7
Dependent Claim
72 words
Radio receiver characterised in that: in a radio receiver which receives paging signals from the transmitting means in a mobile communications system as set forth in Claim 4, there is provided: a means which detects, from the control signal of a received frame, information relating to the number of transmissions; and a means which decides the subframe configuration of said received frame from the detected information relating to the number of transmissions.
