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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) A method as claimed in claim 1, wherein the wireless cellular mobile unit maintains one or more queues, each queue for grouping data pertaining to connections with similar QoS. ### Claim 3 (depends on 1) A method as claimed in claim 1, wherein the wireless cellular mobile unit allocates the UL bandwidth grant to the UL connections further based on an additional communication parameter associated with each UL connection established at the wireless cellular mobile unit. ### Claim 4 (depends on 3) A method as claimed in claim 3, wherein the additional communication parameter includes an information rate assigned to the UL connections. ### Claim 5 (depends on 1) A method as claimed in claim 1, wherein the at least one QoS parameter comprises a connection priority parameter. ### Claim 6 (depends on 1) A method as claimed in claim 1, wherein one of the at least two connections provides a voice service. ### Claim 7 (depends on 1) A method as claimed in claim 1, wherein a connection from the at least two connections provides a voice service, a data service or a video service. ### Claim 8 (depends on 1) A method as claimed in claim 1, wherein a connection from the at least two connections provides a real time service. ### Claim 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;
