Abstract
Abstract A communication network having a master and a plurality of remotes, these remotes supporting a plurality of co-services, in which access to inbound frequencies among the remotes is shared. When a need by a remote for an extraordinary amount of bandwidth is detected, a reserved spillover frequency from a set of frequencies is reserved for that remote. This bandwidth is reallocated when the need for extraordinary bandwidth for that remote has ended.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A communication network having a master and a plurality of remotes, said remotes supporting a plurality of co-services, the network comprising: means for sharing access to a slotted frequency among the remotes; means for detecting a need by a remote for an extraordinary amount of bandwidth, said remote being a demanding remote; means for allocating, to a demanding remote, at least one reserved set of slots corresponding to at least one initial subchannel of said slotted frequency in response to the detection of a need for extraordinary bandwidth for that remote; means for dividing the initial subchannel into separate secondary subchannels and assigning different secondary subchannels to a plurality of different demanding remotes; means for recombining the secondary subchannels which have been divided when the need for extraordinary bandwidth for one of the demanding remotes using one of the divided secondary subchannels has ended.
Claim 2
Dependent Claim
144 words
A communication network having a master and a plurality of remotes, said remotes supporting a plurality of co-services, the network comprising: means for sharing access to a slotted frequency among the remotes; means for detecting a need by a remote for an extraordinary amount of bandwidth, said remote being a demanding remote; means for allocating, to a demanding remote, at least one reserved set of slots corresponding to at least one initial subchannel of said slotted frequency in response to the detection of a need for extraordinary bandwidth for that remote; means for dividing the initial subchannel into separate secondary subchannels and assigning different secondary subchannels to a plurality of different demanding remotes; means for recombining the secondary subchannels which have been divided when the need for extraordinary bandwidth for one of the demanding remotes using one of the divided secondary subchannels has ended.
Claim 3
Dependent Claim
21 words
The network of claim 1, wherein only those secondary subchannels which were originally divided from a common initial subchannel are recombinable.
Claim 4
Dependent Claim
29 words
The network of claim 1, wherein an initial subchannel is divisible only a specified number of times such that the secondary subchannels have a predetermined minimum amount of bandwidth.
Claim 5
Dependent Claim
19 words
The network of claim 1, wherein a frequency has at least two initial subchannels, said initial subchannels being noncombinable.
Claim 6
Dependent Claim
15 words
The network of claim 3, wherein the recombined subchannels are available on a contention basis.
Claim 7
Independent Claim
144 words
A method of subdividing channels of a frequency in a communication network having a master and a plurality of remotes, said remotes supporting a plurality of co-services, the method comprising: sharing access to a slotted frequency among the remotes; detecting a need by a remote for an extraordinary amount of bandwidth, said remote being a demanding remote; allocating, to a demanding remote, at least one reserved set of slots corresponding to at least one initial subchannel of said slotted frequency in response to the detection of a need for extraordinary bandwidth for that remote; dividing the initial subchannel into separate secondary subchannels and assigning different secondary subchannels to a plurality of different demanding remotes; and recombining the secondary subchannels which have been divided when the need for extraordinary bandwidth for one of the demanding remotes using one of the divided secondary subchannels has ended.
Claim 8
Independent Claim
144 words
A method of subdividing channels of a frequency in a communication network having a master and a plurality of remotes, said remotes supporting a plurality of co-services, the method comprising: sharing access to a slotted frequency among the remotes; detecting a need by a remote for an extraordinary amount of bandwidth, said remote being a demanding remote; allocating, to a demanding remote, at least one reserved set of slots corresponding to at least one initial subchannel of said slotted frequency in response to the detection of a need for extraordinary bandwidth for that remote; dividing the initial subchannel into separate secondary subchannels and assigning different secondary subchannels to a plurality of different demanding remotes; and recombining the secondary subchannels which have been divided when the need for extraordinary bandwidth for one of the demanding remotes using one of the divided secondary subchannels has ended.
Claim 9
Dependent Claim
21 words
The method of claim 6, wherein only those secondary subchannels which were originally divided from a common initial subchannel are recombinable.
Claim 10
Dependent Claim
29 words
The method of claim 6, wherein an initial subchannel is divisible only a specified number of times such that the secondary subchannels have a predetermined minimum amount of bandwidth.
Claim 11
Dependent Claim
19 words
The method of claim 6, wherein a frequency has at least two initial subchannels, said initial subchannels being noncombinable.
