Abstract
Abstract In a wireless communication system, unauthorized access may be prevented upon detecting the particular type of identification code. When the identification code is of a default enabled type, the central controller (101) transmits a default enabled message to the system manager (110). The system manager interprets this message and provides a response to the central controller (101). The response may indicate that this particular identification code should be activated or deactivated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
In a wireless communication system, a method for preventing unauthorized access to the wireless communication system, the method comprising the steps of: a) during initialization or re-initialization of the wireless communication system, enabling available identification codes as default enabled identification codes; b) after initialization or re-initialization of the wireless communication system, activating at least one of the available identification codes corresponding to at least one particular communication unit to produce activated identification codes; during operation of the wireless communication system: c) receiving a system access request from a requesting communication unit, wherein the system access request includes an identification code of the requesting communication unit; d) determining whether the identification code is one of the activated identification codes or one of the default enabled identification codes; and e) when the identification code is one of the default enabled identification codes, generating a default enabled message.
Claim 2
Dependent Claim
145 words
In a wireless communication system, a method for preventing unauthorized access to the wireless communication system, the method comprising the steps of: a) during initialization or re-initialization of the wireless communication system, enabling available identification codes as default enabled identification codes; b) after initialization or re-initialization of the wireless communication system, activating at least one of the available identification codes corresponding to at least one particular communication unit to produce activated identification codes; during operation of the wireless communication system: c) receiving a system access request from a requesting communication unit, wherein the system access request includes an identification code of the requesting communication unit; d) determining whether the identification code is one of the activated identification codes or one of the default enabled identification codes; and e) when the identification code is one of the default enabled identification codes, generating a default enabled message.
Claim 3
Dependent Claim
38 words
The method of claim 1 further comprising the steps of: f) routing the default enabled message to a system manager terminal; and g) upon input from the system manager terminal, processing a response to the default enabled message.
Claim 4
Dependent Claim
14 words
The method of claim 2, wherein step (g) further comprises disabling the identification code.
Claim 5
Dependent Claim
14 words
The method of claim 2, wherein step (g) further comprises activating the identification code.
Claim 6
Dependent Claim
114 words
In a wireless communication system, a method for preventing unauthorized access to the wireless communication system, the method comprising the steps of: a) receiving a system access request from a requesting communication unit, wherein the system access request includes an identification code of the requesting communication unit; b) determining whether the identification code is in a set of activated identification codes or a set of default enabled identification codes; c) when the identification code is in the set of default enabled identification codes, determining whether the identification code is in a first set of identification codes; and d) when the identification code is in the first set of identification codes, disabling the identification code.
Claim 7
Dependent Claim
114 words
In a wireless communication system, a method for preventing unauthorized access to the wireless communication system, the method comprising the steps of: a) receiving a system access request from a requesting communication unit, wherein the system access request includes an identification code of the requesting communication unit; b) determining whether the identification code is in a set of activated identification codes or a set of default enabled identification codes; c) when the identification code is in the set of default enabled identification codes, determining whether the identification code is in a first set of identification codes; and d) when the identification code is in the first set of identification codes, disabling the identification code.
Claim 8
Dependent Claim
23 words
The method of claim 5 further comprising the step of: e) informing a system manager terminal of the disabling of the identification code.
Claim 9
Dependent Claim
21 words
The method of claim 6 further comprising the step of: f) upon input from a system manager, activating the identification code.
Claim 10
Dependent Claim
32 words
The method of claim 5, wherein step (d) further comprises the step of: d1) when the identification code is not in the first set of identification codes, generating a default enable message.
Claim 11
Dependent Claim
37 words
The method of claim 8 further comprising the steps of: e) routing the default enabled message to a system manager terminal; and f) upon input from a system manager, processing a response to the default enabled message.
Claim 12
Dependent Claim
18 words
The method of claim 9, wherein step (f) further comprises the step of: f1) disabling the identification code.
Claim 13
Dependent Claim
18 words
The method of claim 9, wherein step (f) further comprises the step of: f1) activating the identification code.
