Abstract
Abstract A method for operating a cellular communications network includes the steps of (a) providing a set of mobile stations that are capable of operating in an idle/sleep mode of operation; (b) transmitting a forward control channel to the set of mobile stations, the forward control channel being organized as a frame structure that is continuously repeated, wherein each frame structure includes an overhead information portion and a plurality of paging information portions; and (c) operating the set of mobile stations to all receive the overhead information portion from every nth frame structure and to receive an assigned one of the paging information portions from every frame structure, wherein n is an integer that is greater than one. The value of n may be fixed or may be made variable. In a presently preferred embodiment of this invention n is equal to six. The method further includes a step of placing individual ones of the set of mobile stations into a low power mode of operation when not receiving the overhead information and paging information portions. In a presently preferred embodiment of this invention the overhead information portion includes at least a system parameter overhead message and may include other overhead messages.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
119 words
A method for operating a cellular communications network, comprising the steps of: providing a set of mobile stations that are capable of operating in an idle sleep mode of operation; transmitting a forward control channel to the set of mobile stations, the forward control channel being organized as a frame structure that is continuously repeated, each frame structure being comprised of an overhead information portion and a plurality of paging information portions; and operating the set of mobile stations in synchronism to all receive the overhead information portion only from every nth frame structure and to receive an assigned one of the paging information portions from every frame structure, wherein n is an integer that is greater than one.
Claim 2
Independent Claim
119 words
A method for operating a cellular communications network, comprising the steps of: providing a set of mobile stations that are capable of operating in an idle sleep mode of operation; transmitting a forward control channel to the set of mobile stations, the forward control channel being organized as a frame structure that is continuously repeated, each frame structure being comprised of an overhead information portion and a plurality of paging information portions; and operating the set of mobile stations in synchronism to all receive the overhead information portion only from every nth frame structure and to receive an assigned one of the paging information portions from every frame structure, wherein n is an integer that is greater than one.
Claim 3
Dependent Claim
40 words
A method as set forth in claim 1, and further comprising a step of placing individual ones of the set of mobile stations into a low power mode of operation when not receiving the overhead information and paging information portions.
Claim 4
Dependent Claim
15 words
A method as set forth in claim 1, wherein the value of n is fixed.
Claim 5
Dependent Claim
16 words
A method as set forth in claim 1, wherein the value of n is a variable.
Claim 6
Dependent Claim
17 words
A method as set forth in claim 1, wherein the value of n is equal to six.
Claim 7
Dependent Claim
33 words
A method as set forth in claim 1, wherein the overhead information portion is comprised at least of a system parameter overhead message, and every nth overhead message portion includes a synchronization message.

Claim 9
Dependent Claim
134 words
A mobile station operable for communicating with a base station, comprising: means for placing said mobile station in an idle sleep mode of operation; means for receiving a forward control channel from the base station, the forward control channel being organized as a frame structure that is continuously repeated, each frame structure being comprised of an overhead information portion and a plurality of paging information portions; and means for operating said mobile station to exit the idle sleep mode of operation to receive, in synchronism with all other idle sleep mode mobile stations that communicate with the base station, the overhead information portion only from every nth frame structure and to receive an assigned one of the paging information portions from every frame structure, wherein n is an integer that is greater than one.
Claim 10
Dependent Claim
134 words
A mobile station operable for communicating with a base station, comprising: means for placing said mobile station in an idle sleep mode of operation; means for receiving a forward control channel from the base station, the forward control channel being organized as a frame structure that is continuously repeated, each frame structure being comprised of an overhead information portion and a plurality of paging information portions; and means for operating said mobile station to exit the idle sleep mode of operation to receive, in synchronism with all other idle sleep mode mobile stations that communicate with the base station, the overhead information portion only from every nth frame structure and to receive an assigned one of the paging information portions from every frame structure, wherein n is an integer that is greater than one.
