Abstract
A system and method for controlling network access for a wireless user subscriber unit having a device identity that utilizes listen-before-talk techniques. A base station is configured to transmit a set of device identities corresponding to a set of valid subscriber units. A user subscriber unit is configured to listen for a device identity corresponding to the user subscriber unit. Further, the user subscriber unit is configured to transmit a request for network access upon receiving the device identity corresponding to the user subscriber unit when network access is desired.
Claims23
A method for controlling wireless network access for a wireless user subscriber unit having a device identity, the method comprising:
- listening with the user subscriber unit;
- transmitting a set of device identities corresponding to a set of valid subscriber units from a base station;
- granting a specified amount of time for response to the set of valid subscriber units upon transmitting the set of device identities;
- upon receiving the device identity corresponding to the user subscriber unit, transmitting a request for network access with the user subscriber unit within the specified amount of time;
- and
- granting network access to the user subscriber unit upon receiving the request for network access at the base station.
A system for controlling wireless network access, the system comprising:
- a user subscriber unit configured to listen for a device identity corresponding to the user subscriber unit, and configured to transmit a request for network access upon receiving the device identity corresponding to the user subscriber unit when network access is desired;
- and
- a base station configured to transmit a set of device identities corresponding to a set of valid subscriber units, and configured to grant a specified amount of time for response to the set of valid subscriber units upon transmitting the set of device identities, and further configured to grant network access to the user subscriber unit upon receiving the request for network access at the base station within the specified time for response.
A user wireless device for use in a wireless network in which the user wireless device is permitted to access the network when the user wireless device is within a preselected fixed region with at least one base station in the region that is operative to permit network access for a predetermined plurality of wireless devices including the user wireless device, the user wireless device comprising:
- a user subscriber unit configured to listen for a device identity corresponding to the user subscriber unit, the device identity being transmitted along with a plurality of other device identities corresponding to other wireless devices by the at least one base station, and the user subscriber unit being further configured to transmit a request for network access after receiving the device identity corresponding to the user subscriber unit when network access is desired.
A system for controlling wireless network access, the system comprising:
- a user subscriber unit configured to listen for a device identity corresponding to the user subscriber unit, and configured to transmit a request for network access upon receiving the device identity corresponding to the user subscriber unit when network access is desired;
- and
- a base station configured to transmit a set of device identities corresponding to a set of valid subscriber units.
A method for controlling wireless network access for a wireless user subscriber unit having a device identity, the method comprising:
- listening with the user subscriber unit;
- transmitting a set of device identities corresponding to a set of valid subscriber units from a base station;
- and
- upon receiving the device identity corresponding to the user subscriber unit, transmitting a request for network access with the user subscriber unit.
