Abstract
Abstract A channel structure for use in communication systems. Two sets of physical channels, one for the forward link and another for the reverse link, are utilized to facilitate communication of a variety of logical channels. The physical channels comprise data and control channels. In the exemplary embodiment, the data channels comprise fundamental channels which are used to transmit voice traffic, data traffic, high speed data, and other overhead information and supplemental channels which are used to transmit high speed data. The fundamental channels can be released when the remote stations are idle to more fully utilized the available capacity. The control channels are used to transmit paging and control messages and scheduling information.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
216 words
A method for operating a remote station in a plurality of activity modes comprising: operating said remote station in a traffic mode in which dedicated traffic channels are allocated to said remote station when said remote station is actively receiving and transmitting data; storing, in the remote station, a Radio Link Protocol (RLP) state associated with an active data session of said traffic mode; storing a traffic channel configuration associated with said traffic mode; storing encryption variables associated with said traffic mode; operating said remote station in a suspended mode wherein said dedicated traffic channels are de-allocated and said remote station monitors a paging channel in a non-slotted mode when a traffic mode time interval, in which said remote station operates in the traffic mode and neither transmits nor receives data, exceeds a first threshold interval; operating said remote station in a dormant mode wherein said remote station monitors said paging channel in a slotted mode when a suspended mode time interval in which said remote station operates in the suspended mode and neither transmits nor receives data exceeds a second threshold interval; and utilizing the stored RLP state, the stored traffic channel configuration, and the stored encryption variables for the transmission and reception of traffic after receiving a channel assignment message on said paging channel.
Claim 2
Independent Claim
216 words
A method for operating a remote station in a plurality of activity modes comprising: operating said remote station in a traffic mode in which dedicated traffic channels are allocated to said remote station when said remote station is actively receiving and transmitting data; storing, in the remote station, a Radio Link Protocol (RLP) state associated with an active data session of said traffic mode; storing a traffic channel configuration associated with said traffic mode; storing encryption variables associated with said traffic mode; operating said remote station in a suspended mode wherein said dedicated traffic channels are de-allocated and said remote station monitors a paging channel in a non-slotted mode when a traffic mode time interval, in which said remote station operates in the traffic mode and neither transmits nor receives data, exceeds a first threshold interval; operating said remote station in a dormant mode wherein said remote station monitors said paging channel in a slotted mode when a suspended mode time interval in which said remote station operates in the suspended mode and neither transmits nor receives data exceeds a second threshold interval; and utilizing the stored RLP state, the stored traffic channel configuration, and the stored encryption variables for the transmission and reception of traffic after receiving a channel assignment message on said paging channel.
Claim 3
Dependent Claim
25 words
The method of claim 1 further comprising releasing said at least one traffic channel after the traffic mode time interval exceeds the first threshold period.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said first threshold period is approximately one second.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein said second threshold period is approximately sixty seconds.
Claim 6
Dependent Claim
26 words
The method of claim 1 further comprising sending a location update message to a base station during said operating said remote station in a suspended mode.
Claim 7
Dependent Claim
29 words
The method of claim 1 further comprising storing authentication variables associated with said traffic mode in said remote station during said operating said remote station in a suspended mode.
Claim 8
Dependent Claim
48 words
The method of claim 1 further comprising: storing state information in said remote station during said operating said remote station in a suspended mode; and upon receiving, at said remote station, a channel assignment message, bringing said remote station back to said traffic mode using said state information.
Claim 9
Dependent Claim
12 words
The method of claim 7 wherein said state information comprises authentication variables.
