Abstract
Abstract A method for registering a mobile station when the mobile station first enters a communication system which supports packet data channels is disclosed. The mobile station receives system information broadcasted on a digital control channel. The mobile station is then assigned to a beacon packet data channel over which the mobile station registers with the communication system.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
59 words
A method for registering a mobile station when the mobile station first enters a communication system which supports packet data channels, comprising the steps of: receiving at said mobile station system information broadcast on a digital control channel; assigning said mobile station to a beacon packet data channel; registering with said communication system over said beacon packet data channel.
Claim 2
Independent Claim
59 words
A method for registering a mobile station when the mobile station first enters a communication system which supports packet data channels, comprising the steps of: receiving at said mobile station system information broadcast on a digital control channel; assigning said mobile station to a beacon packet data channel; registering with said communication system over said beacon packet data channel.
Claim 3
Dependent Claim
30 words
A method according to claim 1, wherein said mobile station is assigned to the beacon packet data channel by a packet data channel pointer assigned to said digital control channel.
Claim 4
Dependent Claim
27 words
A method according to claim 1, further comprising the step of: reassigning said mobile station from said beacon packet data channel to a second packet data channel.
Claim 5
Dependent Claim
17 words
A method according to claim 1, wherein said mobile station is reassigned based on past service requests.
Claim 6
Dependent Claim
17 words
A method according to claim 1, wherein said mobile station is reassigned based on current service requests.
Claim 7
Dependent Claim
19 words
A method according to claim 1, wherein said mobile station is reassigned based on past and current service requests.
Claim 8
Dependent Claim
25 words
A method according to claim 1, wherein said system information includes a neighbor list containing frequencies of other digital control channels used in neighboring cells.
Claim 9
Dependent Claim
117 words
A cell reselection method for a mobile station operating in a communication system which supports packet data channels, comprising the steps of: receiving at said mobile station system information broadcast on a digital control channel; assigning said mobile station to a beacon packet data channel; registering with said communication system over said beacon packet data channel; measuring signal strength of digital control channels of neighboring cells listed on a neighbor list included in said system information and said first digital control channel; assigning said mobile station to a digital control channel of a neighboring cell when the signal strength of the neighboring digital control channel is higher than the signal strength of said first digital control channel.
Claim 10
Dependent Claim
117 words
A cell reselection method for a mobile station operating in a communication system which supports packet data channels, comprising the steps of: receiving at said mobile station system information broadcast on a digital control channel; assigning said mobile station to a beacon packet data channel; registering with said communication system over said beacon packet data channel; measuring signal strength of digital control channels of neighboring cells listed on a neighbor list included in said system information and said first digital control channel; assigning said mobile station to a digital control channel of a neighboring cell when the signal strength of the neighboring digital control channel is higher than the signal strength of said first digital control channel.
Claim 11
Dependent Claim
30 words
A method according to claim 8, wherein said mobile station is assigned to the beacon packet data channel by a packet data channel pointer assigned to said digital control channel.
Claim 12
Dependent Claim
27 words
A method according to claim 8, further comprising the step of: reassigning said mobile station from said beacon packet data channel to a second packet data channel.
Claim 13
Dependent Claim
17 words
A method according to claim 8, wherein said mobile station is reassigned based on past service requests.
Claim 14
Dependent Claim
17 words
A method according to claim 8, wherein said mobile station is reassigned based on current service requests.
Claim 15
Dependent Claim
19 words
A method according to claim 8, wherein said mobile station is reassigned based on past and current service requests.
Claim 16
Dependent Claim
17 words
A method according to claim 8, wherein each packet data channel provides a mobile station local information.
Claim 17
Dependent Claim
26 words
A method according to claim 14, wherein said local information includes a bit map vector which indicates which of the neighboring cells supports packet data channels.
