Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A method for selecting a control channel in a radio communication network comprising the steps of: receiving, at a remote station, an offset on a control channel; evaluating, in said remote station, a plurality of control channels using a cell selection function to generate a cell selection value associated with each of said plurality of control channels, wherein said cell selection function subtracts said offset for control channels associated with cells that do not offer a desired service; and selecting a control channel based on said cell selection value.
Claim 2
Independent Claim
89 words
A method for selecting a control channel in a radio communication network comprising the steps of: receiving, at a remote station, an offset on a control channel; evaluating, in said remote station, a plurality of control channels using a cell selection function to generate a cell selection value associated with each of said plurality of control channels, wherein said cell selection function subtracts said offset for control channels associated with cells that do not offer a desired service; and selecting a control channel based on said cell selection value.
Claim 3
Dependent Claim
14 words
The method of claim 1, where in said remote station is a mobile station.
Claim 4
Independent Claim
96 words
A method for selecting one control channel from a plurality of control channels by a mobile station comprising the steps of: broadcasting a predetermined offset; evaluating each of said plurality of control channels based upon a signal strength at which each control channel is received and an availability of a service using each control channel wherein a selection value associated with each control channel is lowered by a predetermined offset if a cell associated with said control channel does not offer said service; and selecting said one control channel based on results of said evaluating step.
Claim 5
Independent Claim
96 words
A method for selecting one control channel from a plurality of control channels by a mobile station comprising the steps of: broadcasting a predetermined offset; evaluating each of said plurality of control channels based upon a signal strength at which each control channel is received and an availability of a service using each control channel wherein a selection value associated with each control channel is lowered by a predetermined offset if a cell associated with said control channel does not offer said service; and selecting said one control channel based on results of said evaluating step.
Claim 6
Dependent Claim
90 words
A remote station comprising: means for evaluating a plurality of control channels using a cell selection function to generate a cell selection value associated with each of said plurality of control channels, wherein said cell selection function includes a parameter associated with a desired service and further including means for subtracting an offset received on a broadcast control channel in said cell selection function for control channels associated with cells that do not offer said desired service; and means for selecting a control channel based on said cell selection value.
Claim 7
Dependent Claim
90 words
A remote station comprising: means for evaluating a plurality of control channels using a cell selection function to generate a cell selection value associated with each of said plurality of control channels, wherein said cell selection function includes a parameter associated with a desired service and further including means for subtracting an offset received on a broadcast control channel in said cell selection function for control channels associated with cells that do not offer said desired service; and means for selecting a control channel based on said cell selection value.
Claim 8
Dependent Claim
87 words
A remote station comprising: means for evaluating each of a plurality of control channels based upon a signal strength at which each control channel is received and an availability of a service using each control channel wherein a selection value associated with each control channel is lowered by a predetermined offset received on a broadcast control channel if a cell associated with said control channel does not offer said service; and means for selecting said one control channel based on results generated by said means for evaluating.
Claim 9
Dependent Claim
87 words
A remote station comprising: means for evaluating each of a plurality of control channels based upon a signal strength at which each control channel is received and an availability of a service using each control channel wherein a selection value associated with each control channel is lowered by a predetermined offset received on a broadcast control channel if a cell associated with said control channel does not offer said service; and means for selecting said one control channel based on results generated by said means for evaluating.
