1. A rate allocation method, comprising:
- adapting, by a processor, a control parameter value as user equipment (UE) enter a network sector based on a total load for tagged UE of the network sector and a determination to tag a prospective new UE, wherein the tagged UEs of the network sector correspond with all current and prospective network sector UEs that entered the network sector at an instance when the processor determined that the free capacity of the network sector is larger than or equal to a capacity threshold;
assigning, by the processor, a provisional rate for the prospective new UE of the network sector based on the control parameter value and a determined marginal pay-off for admitting the prospective new UE;
determining, by the processor, free capacity of the network sector;
admitting, by the processor, the prospective new UE if enough free capacity exists in order for the network sector to service the prospective new UE at the provisional rate,wherein this method is accomplished without the knowledge of channel and traffic statistics of the network sector.

Abstract
A method and an apparatus for adaptively allocating available bandwidth for network users. The method is particularly beneficial in improving a viewing experience for mobile devices accessing the network, while also maximizing the number of supported users within the network. An adaptively adjusted control parameter is used in conjunction with a utility function to assign a provisional rate for users entering the network. Based on the assigned provisional rate, the method then admits prospective new network users, if enough free capacity exists to service the new user at the provisional rate.

11. A device, comprising:
a processor, configured to, adapt a control parameter value as user equipment (UE) enter a network sector based on a total load for tagged UE of the network sector and a determination to tag a prospective new UE, wherein the tagged UEs of the network sector correspond with all current and prospective network sector UEs that entered the network sector at an instance when the processor determined that the free capacity of the network sector is larger than or equal to a capacity threshold; assign a provisional rate for the prospective new UE of the network sector based on the control parameter value and a determined marginal pay-off for admitting the prospective new UE; determine free capacity of the network sector; admit the prospective new UE if enough free capacity exists in order for the network sector to service the prospective new UE at the provisional rate, wherein the processor does not require knowledge of channel and traffic statistics of the network sector. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
