Abstract
Abstract A portion of the bits within an assigned Temporary Mobile Station Identification (TMSI) number are encoded based upon a subscriber's group classifications (i.e., classifications based on the user's characteristics, such as subscriber services and affiliation). When a mobile station user requests service in a visiting location, the user's service profile is accessed to determine the user's group classifications (if any). The mobile station is assigned a TMSI number according to the user's accessed service profile and a portion of bits associated with the TMSI number are encoded based on the identifiable user group classification. The length of the assigned TMSI number may be adjusted depending upon the particular application to maximize the number of TMSI numbers that may be transmitted in a single paging slot.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
75 words
A method for operating a wireless telecommunications network, the network having associated therewith a group of at least one mobile station having an identifiable classification denoting subscriber affiliations or services, the method comprising the steps of: (a) assigning a temporary identification number to the mobile station belonging to the identifiable classification, the temporary identification number comprising a plurality of bits; and (b) encoding a portion of the plurality of bits based on the identifiable classification.
Claim 2
Independent Claim
75 words
A method for operating a wireless telecommunications network, the network having associated therewith a group of at least one mobile station having an identifiable classification denoting subscriber affiliations or services, the method comprising the steps of: (a) assigning a temporary identification number to the mobile station belonging to the identifiable classification, the temporary identification number comprising a plurality of bits; and (b) encoding a portion of the plurality of bits based on the identifiable classification.
Claim 3
Dependent Claim
31 words
The method according to claim 1, further comprising the step of storing a user profile associated with the mobile station, the user profile identifying any classification assigned to the mobile station.
Claim 4
Dependent Claim
40 words
The method according to claim 2, further comprising the steps of: (a) retrieving the user profile associated with the mobile station; and (b) determining whether the mobile station is assigned to an identifiable classification based upon the retrieved user profile.
Claim 5
Dependent Claim
19 words
The method according to claim 3, wherein the user profile is stored within a home location register (HLR) database.
Claim 6
Dependent Claim
38 words
The method according to claim 4, further comprising the steps of: (a) copying the retrieved user profile associated with the mobile station; and (b) transmitting the copied user profile to a mobile switching center servicing the mobile station.
Claim 7
Dependent Claim
26 words
The method according to claim 5, wherein the transmitted user profile is stored in a visitor location register (VLR) database associated with the mobile switching center.
Claim 8
Dependent Claim
28 words
The method according to claim 3, wherein the user profile associated with the mobile station is retrieved based upon a permanent identification number assigned to the mobile station.
Claim 9
Dependent Claim
26 words
The method according to claim 7, wherein the permanent identification number assigned to the mobile station is the mobile station's International Mobile Station Identification (IMSI) number.
Claim 10
Dependent Claim
24 words
The method according to claim 7, wherein the permanent identification number assigned to the mobile station is the mobile station's Mobile Identification Number (MIN).
Claim 11
Dependent Claim
28 words
The method according to claim 1, wherein at least one bit of the encoded plurality of bits identifies whether the mobile station is assigned to an identifiable classification.
Claim 12
Dependent Claim
31 words
The method according to claim 1, wherein the length of the assigned temporary identification number is dependent upon the identifiable classification to efficiently utilize paging slots within the wireless telecommunications network.
Claim 13
Independent Claim
87 words
A method of classifying at least one mobile station within a wireless telecommunications network as an identifiable classification denoting subscriber affiliations or services, comprising the steps of: (a) storing a user profile associated with the mobile station, the user profile identifying the classification assigned to the mobile station; (b) assigning a temporary identification number to the mobile station belonging to the identifiable classification, the temporary identification number comprising a plurality of bits; and (c) encoding a portion of the plurality of bits based on the identifiable classification.
Claim 14
Independent Claim
87 words
A method of classifying at least one mobile station within a wireless telecommunications network as an identifiable classification denoting subscriber affiliations or services, comprising the steps of: (a) storing a user profile associated with the mobile station, the user profile identifying the classification assigned to the mobile station; (b) assigning a temporary identification number to the mobile station belonging to the identifiable classification, the temporary identification number comprising a plurality of bits; and (c) encoding a portion of the plurality of bits based on the identifiable classification.
Claim 15
Dependent Claim
28 words
The method according to claim 12, wherein at least one bit of the encoded plurality of bits identifies whether the mobile station is assigned to an identifiable classification.
Claim 16
Dependent Claim
40 words
The method according to claim 12, further comprising the steps of: (a) retrieving the user profile associated with the mobile station; and (b) determining whether the mobile station is assigned to an identifiable classification based upon the retrieved user profile.
Claim 17
Dependent Claim
19 words
The method according to claim 14, wherein the user profile is stored within a home location register (HLR) database.
Claim 18
Dependent Claim
38 words
The method according to claim 15, further comprising the steps of: (a) copying the retrieved user profile associated with the mobile station; and (b) transmitting the copied user profile to a mobile switching center servicing the mobile station.
Claim 19
Dependent Claim
26 words
The method according to claim 16, wherein the transmitted user profile is stored in a visitor location register (VLR) database associated with the mobile switching center.
Claim 20
Dependent Claim
28 words
The method according to claim 14, wherein the user profile associated with the mobile station is retrieved based upon a permanent identification number assigned to the mobile station.
Claim 21
Dependent Claim
26 words
The method according to claim 18, wherein the permanent identification number assigned to the mobile station is the mobile station's International Mobile Station Identification (IMSI) number.
Claim 22
Dependent Claim
24 words
The method according to claim 18, wherein the permanent identification number assigned to the mobile station is the mobile station's Mobile Identification Number (MIN).
