Abstract
Abstract The wireless communication device receives a neighbor list message from a first base station. The neighbor list message includes a respective base station configuration parameter for each of a plurality of base stations. In response to the neighbor list message, the wireless communication device constructs a neighbor list table, including one record for each of the plurality of base stations, with each record including their respective base station configuration parameter. After handing off to a second base station, the wireless communication device replaces the record for the second base station with a corresponding record for the first base station. The wireless communication device then may change the respective base station configuration parameter for at least one of the records of the plurality of base stations in the neighbor list table to match the base station configuration parameter of the second base station.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A method for constructing a temporary list of neighboring base station parameters in a wireless communication device, the method comprising the steps of: receiving a neighbor list message from a first base station, said neighbor list message including a respective base station configuration parameter for each of a plurality of base stations, said plurality of base stations including a second base station; constructing a neighbor list table in response to said neighbor list message, said neighbor list table including one record for each of said plurality of base stations, each record including said respective base station configuration parameter; determining whether a second neighbor list message has been received from said second base station; and replacing said record for said second base station with a corresponding record for said first base station if said second neighbor list message is not received from said second base station.
Claim 2
Independent Claim
145 words
A method for constructing a temporary list of neighboring base station parameters in a wireless communication device, the method comprising the steps of: receiving a neighbor list message from a first base station, said neighbor list message including a respective base station configuration parameter for each of a plurality of base stations, said plurality of base stations including a second base station; constructing a neighbor list table in response to said neighbor list message, said neighbor list table including one record for each of said plurality of base stations, each record including said respective base station configuration parameter; determining whether a second neighbor list message has been received from said second base station; and replacing said record for said second base station with a corresponding record for said first base station if said second neighbor list message is not received from said second base station.
Claim 3
Dependent Claim
30 words
The method of claim 1 further comprising the step of changing said respective base station configuration parameter for at least one of said records of said plurality of base stations.
Claim 4
Dependent Claim
50 words
The method of claim 2 wherein the step of changing said respective base station configuration parameter for said at least one of said records of said plurality of base stations comprises changing said respective base station configuration parameter to match the base station configuration parameter of said second base station.
Claim 5
Dependent Claim
189 words
The method of claim 3 wherein said base station configuration parameter has at least three possible values, a first value representing that a corresponding one of said plurality of base stations has a same configuration as said first base station, a second value representing that said corresponding one of said plurality of base stations has a different number of paging channels than said first base station, and a third value representing that said corresponding one of said plurality of base stations has a different number of frequency assignments than said first base station, said step of changing said respective base station configuration parameter for said at least one of said records of said plurality of base stations further comprising the steps of: changing said base station configuration parameter from said first value to said second value if said base station configuration parameter of said second base station is equal to said second value; and changing said base station configuration parameter from said first value or said second value to said third value if said base station configuration parameter of said second base station is equal to said third value.
Claim 6
Dependent Claim
165 words
A circuit for constructing a temporary list of neighboring base station parameters in a wireless communication device, the circuit comprising: a receiver for receiving a neighbor list message from a first base station, said neighbor list message including a respective base station configuration parameter for each of a plurality of base stations, said plurality of base stations including a second base station; and a control processor, coupled to said receiver, for constructing a neighbor list table in response to said neighbor list message, said neighbor list table including one record for each of said plurality of base stations, each record including said respective base station configuration parameter; said control processor further for determining whether said receiver has received a second neighbor list message from said second base station and for replacing said record for said second base station with a corresponding record for said first base station after determining that said receiver did not receive said second neighbor list message from said second base station.
Claim 7
Dependent Claim
165 words
A circuit for constructing a temporary list of neighboring base station parameters in a wireless communication device, the circuit comprising: a receiver for receiving a neighbor list message from a first base station, said neighbor list message including a respective base station configuration parameter for each of a plurality of base stations, said plurality of base stations including a second base station; and a control processor, coupled to said receiver, for constructing a neighbor list table in response to said neighbor list message, said neighbor list table including one record for each of said plurality of base stations, each record including said respective base station configuration parameter; said control processor further for determining whether said receiver has received a second neighbor list message from said second base station and for replacing said record for said second base station with a corresponding record for said first base station after determining that said receiver did not receive said second neighbor list message from said second base station.
Claim 8
Dependent Claim
32 words
The circuit of claim 5 wherein said control processor is further for changing said respective base station configuration parameter for at least one of said records of said plurality of base stations.
Claim 9
Dependent Claim
28 words
The circuit of claim 6 wherein said control processor changes said respective base station configuration parameter to match the base station configuration parameter of said second base station.
Claim 10
Dependent Claim
165 words
The circuit of claim 7 wherein said base station configuration parameter has at least three possible values, a first value representing that a corresponding one of said plurality of base stations has a same configuration as said first base station, a second value representing that said corresponding one of said plurality of base stations has a different number of paging channels than said first base station, and a third value representing that said corresponding one of said plurality of base stations has a different number of frequency assignments than said first base station, and wherein said control processor: changes said base station configuration parameter from said first value to said second value if said base station configuration parameter of said second base station is equal to said second value; and changes said base station configuration parameter from said first value or said second value to said third value if said base station configuration parameter of said second base station is equal to said third value.
