1. A method of operating a wireless cellular mobile unit registered with a base station in a bandwidth on demand wireless cellular communication system, the method comprising:
- transmitting from the wireless cellular mobile unit a one bit message requesting to be provided an allocation of uplink (UL) bandwidth in which to transmit a bandwidth request for at least one connection served by the wireless cellular mobile unit;
receiving at the wireless cellular mobile unit the allocation of UL bandwidth in which to transmit the bandwidth request, the allocation of UL bandwidth received pursuant to the one bit message;
transmitting from the wireless cellular mobile unit the bandwidth request within the allocation of UL bandwidth, the bandwidth request being indicative of a pending amount of UL data associated with the at least one connection;
receiving at the wireless cellular mobile unit an UL bandwidth grant for the wireless cellular mobile unit, the UL bandwidth grant received pursuant to the bandwidth request; and
allocating the received UL bandwidth grant to at least two UL connections served by the wireless cellular mobile unit, based on a QoS parameter of the at least two UL connections.

Abstract
A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

9. A method of allocating uplink (UL) bandwidth on demand in a wireless cellular communication system wherein a wireless cellular mobile unit is registered with, and communicates with a base station, the method comprising:
-
determining an amount of pending UL data for a UL connection served by the wireless cellular mobile unit; transmitting from the wireless cellular mobile unit a one bit message to the base station requesting to be provided an allocation of UL bandwidth in which to transmit a bandwidth request; receiving at the wireless cellular mobile unit the allocation of UL bandwidth in which to transmit the bandwidth request; transmitting to the base station, within the allocation of UL bandwidth, the bandwidth request indicative of the amount of UL pending data for the UL connection; receiving from the base station an UL bandwidth grant for the wireless cellular mobile unit; and allocating, at the wireless cellular mobile unit, the UL bandwidth grant to at least two connections served by the wireless cellular mobile unit; wherein the wireless cellular mobile unit allocates the UL bandwidth grant to the at least two connections based on a QoS parameter of at least one of the UL connections. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of allocating uplink (UL) bandwidth on demand in a wireless communication network, wherein a wireless cellular mobile unit is registered with, and communicating with a base station, the method comprising:
-
transmitting from the wireless cellular mobile unit a one bit message to the base station to request an allocation of UL bandwidth in which to transmit a bandwidth request; receiving at the wireless cellular mobile unit the allocation of UL bandwidth in which to transmit the bandwidth request; transmitting to the base station, within the allocation of UL bandwidth, the bandwidth request indicative of an amount of pending UL data; receiving from the base station an UL bandwidth grant for the wireless cellular mobile unit; and transmitting to the base station UL data of the pending UL data pursuant to the UL bandwidth grant; wherein the transmitted UL data is transmitted for at least two UL services and wherein the UL data is transmitted for the at least two UL services based on a QoS parameter of a respective service from the at least two UL services. - View Dependent Claims (18, 19, 20)
