Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
60 words
A method for monitoring radio link quality in a radiocommunication system comprising the steps of: initializing a counter; performing a cyclic redundancy check (CRC) on information read during a timeslot of a paging frame; incrementing said counter if said CRC is successful; decrementing said counter if said CRC fails; and indicating a radio link failure when said counter reaches zero.
Claim 2
Independent Claim
60 words
A method for monitoring radio link quality in a radiocommunication system comprising the steps of: initializing a counter; performing a cyclic redundancy check (CRC) on information read during a timeslot of a paging frame; incrementing said counter if said CRC is successful; decrementing said counter if said CRC fails; and indicating a radio link failure when said counter reaches zero.
Claim 3
Dependent Claim
24 words
The method of claim 1, wherein said step of initializing said counter further comprises the step of: setting said counter to value of ten.
Claim 4
Dependent Claim
25 words
The method of claim 1, further comprising the step of: once a radio link failure occurs, performing measurements on frequencies identified in a neighbor list.
Claim 5
Dependent Claim
23 words
The method of claim 2, further comprising the step of: truncating a value of said counter such that it does not exceed ten.
Claim 6
Dependent Claim
24 words
The method of claim 1, further comprising the step of: using said CRC from only one timeslot per paging frame to update said counter.
Claim 7
Dependent Claim
53 words
A mobile station comprising: a receiver for receiving information in a timeslot of a paging frame; a counter; and a processor configured to: initialize said counter when said mobile station camps on a control channel; perform a CRC on said information; and selectively update said counter based on a result of said CRC.
Claim 8
Dependent Claim
53 words
A mobile station comprising: a receiver for receiving information in a timeslot of a paging frame; a counter; and a processor configured to: initialize said counter when said mobile station camps on a control channel; perform a CRC on said information; and selectively update said counter based on a result of said CRC.
Claim 9
Dependent Claim
21 words
The mobile station of claim 6, wherein said processor is further configured to initialize said counter to a value of 10.
Claim 10
Dependent Claim
23 words
The mobile station of claim 6, wherein said processor is further configured to indicate a radio link failure when said counter reaches zero.
Claim 11
Dependent Claim
30 words
The mobile station of claim 8, wherein said processor is further configured to perform signal strength measurements on frequencies in a neighbor list when said radio link failure is declared.
