Abstract
Abstract In a method for controlling admission of remote hosts to a base station in a wireless communications network based on usage priority, there are at least two user priority classes and the base station admits a threshold number of remote hosts of the lower priority class and a maximum total number of remote hosts. When a base station receives a connection request from a new user of the higher priority class, if the current total number of admitted users is less than the maximum allowable, the new user of class is admitted, otherwise, the base station checks to see if any lower priority class users are currently admitted and allow disconnection. If so, the base station disconnect the lower priority user and admits the new user. In one embodiment, the base station disconnects the "least recently used" admitted lower priority user that allows disconnection. If it is appropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted as long as the total number of associated users is less than the maximum allowable admitted users. If it is inappropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted only if the number of admitted users is less than the maximum number of total admitted users and the number of lower priority admitted users is less than the maximum allowable admitted number. This approach can be extended to multiple priority classes. In an alternate embodiment, lower priority class users are admitted if the total number of currently associated users of all classes is less than a second threshold, normally lower than the threshold for higher priority users, rather than being based partially (as a second threshold) on the number of currently associated users of that lower priority class.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A method for controlling admission of remote hosts to a communications
network based on usage priority, said network having a base station and supporting
connection to plural classes of remote hosts, said classes of remote hosts including at
least a first priority class and a second priority class, said network supporting
admission of a maximum total number of said remote hosts, and a maximum number
of second priority ones of said remote hosts, the method comprising the steps, in
combination, of: receiving at said base station a connection request from an unadmitted
one of said remote hosts belonging to said first priority class; admitting said unadmitted remote host from said first priority class if
the total number of admitted remote hosts is less than said maximum total number of
admitted remote hosts; and if the number of admitted remote hosts equals said maximum total
number of admitted remote hosts, the number of admitted second priority class remote
hosts is at least one, and at least one of said admitted second priority class remote
hosts allows disconnection, disconnecting one of said second priority class remote
hosts allowing disconnection in order to admit said unadmitted remote host from said
first priority class.
Claim 2
Dependent Claim
27 words
The method of claim 1, wherein the step of disconnecting a second priority
remote host, disconnects a least recently used remote host of said second priority
class.
Claim 3
Dependent Claim
75 words
The method of claim 1, further comprising the steps, in combination, of: receiving at said base station a connection request from an unadmitted
remote host, said unadmitted remote host belonging to said second priority class; and admitting said unadmitted second priority class remote host when the
number of admitted remote hosts is less than said maximum total number of admitted
remote hosts and said unadmitted second priority remote host indicates that premature
disconnection is allowed.
Claim 4
Dependent Claim
70 words
The method of claim 3, further comprising the step of admitting said
unadmitted second priority class remote host when: the number of admitted remote hosts is less than said maximum total
number of admitted remote hosts; the number of admitted second priority class remote hosts is less than
said maximum number of second priority remote hosts; and said unadmitted second priority class remote host indicates that
premature disconnection is inappropriate.
Claim 5
Dependent Claim
96 words
The method of claim 1, further comprising the steps, in combination, of: receiving at said base station a connection request from an unadmitted
remote host, said unadmitted remote host belonging to said second priority class; and admitting said unadmitted second priority class remote host when: the number of admitted remote hosts is less than said maximum
total number of admitted remote hosts; the number of admitted second priority class remote hosts is less
than said maximum number of second priority remote hosts; and said unadmitted second priority class remote host indicates that
premature disconnection is inappropriate.
Claim 6
Independent Claim
225 words
A method for controlling admission of remote hosts to a communications
network based on usage priority, said network having a base station and supporting
connection to plural classes of remote hosts, said classes of remote hosts including at
least a first priority class and a second priority class, said network supporting
admission of a first maximum total number of admitted ones of said remote hosts,
said first maximum total number of admitted ones of said remote hosts being a
threshold value applied during admission of said first priority remote hosts, the
method comprising the steps, in combination, of: receiving at said base station a connection request from an unadmitted
one of said remote hosts belonging to said first priority class; admitting said unadmitted remote host from said first priority class if
the total number of admitted ones of said remote hosts is less than said first maximum
total number of admitted remote hosts; and if the number of admitted first priority class remote hosts equals said
first maximum total number of admitted remote hosts, the number of admitted second
priority class remote hosts is at least one, and at least one of said admitted second
priority class remote hosts allows disconnection, disconnecting one of said second
priority class remote hosts allowing disconnection in order to admit said unadmitted
remote host from said first priority class.
Claim 7
Dependent Claim
27 words
The method of claim 6, wherein the step of disconnecting a second priority
remote host, disconnects a least recently used remote host of said second priority
class.
Claim 8
Dependent Claim
76 words
The method of claim 6, further comprising the steps, in combination, of: receiving at said base station a connection request from an unadmitted
remote host, said unadmitted remote host belonging to said second priority class; and admitting said unadmitted second priority class remote host when the
number of admitted remote hosts is less than said first maximum total number of
admitted remote hosts and said unadmitted second priority remote host indicates that
premature disconnection is allowed.
Claim 9
Dependent Claim
105 words
The method of claim 8, wherein said network supports admission of a
second maximum total number of admitted ones of said remote hosts, said second
maximum total number of admitted remote hosts being less than said first maximum
total number of said remote hosts and being a threshold value applied during
admission of said second priority remote hosts, further comprising the step of
admitting said unadmitted second priority class remote host when: the total number of admitted remote hosts is less than said second
maximum total number of admitted remote hosts; and said unadmitted second priority class remote host indicates that
premature disconnection is inappropriate.
Claim 10
Dependent Claim
138 words
The method of claim 6, wherein said network supports admission of a
second maximum total number of admitted ones of said remote hosts, said second
maximum total number of admitted remote hosts said second maximum total number
of admitted remote hosts being less than said first maximum total number of said
remote hosts and being a threshold value applied during admission of said second
priority remote hosts, further comprising the steps, in combination, of: receiving at said base station a connection request from an unadmitted
remote host, said unadmitted remote host belonging to said second priority class; and admitting said unadmitted second priority class remote host when: the number of admitted remote hosts is less than said second
maximum number of admitted remote hosts; and said unadmitted second priority class remote host indicates that
premature disconnection is inappropriate.
