Abstract

An RF communication system comprises RF circuitry, access circuitry, and control circuitry. The RF circuitry receives reverse packets from users over reverse RF links. The access circuitry is operationally coupled to the RF circuitry and transfers the reverse packets over a reverse network link. The control circuitry is operationally coupled to the access circuitry and inhibits the transfer of a set of the reverse packets over the reverse network link in response to a reverse overload condition on the reverse network link. The inhibited set of the reverse packets are from the users having a lowest level of reverse packet loss on the reverse RF links.

Dependent claims

A Radio Frequency (RF) communication system comprising:

RF communication circuitry configured to receive reverse packets from a plurality of user devices over a plurality of reverse RF links associated with the user devices and transfer forward packets to the user devices over a plurality of forward RF links associated with the user devices;
access communication circuitry operationally coupled to the RF communication circuitry and configured to transfer the reverse packets over a reverse backhaul link and receive the forward packets over a forward backhaul link;
network communication circuitry operationally coupled to a communication network and configured to transfer the forward packets over the forward backhaul link and to receive the reverse packets over the reverse backhaul link;
control circuitry is operationally coupled to the network communication circuitry and configured to inhibit the transfer of a set of the forward packets over the forward backhaul link in response to a forward overload condition on the forward backhaul link, wherein the inhibited set of the forward packets are directed to ones of the user devices having a lowest level of forward packet loss on the forward RF links;
and
the control circuitry operationally coupled to the access communication circuitry and configured to inhibit the transfer of a set of the reverse packets over the reverse backhaul link in response to a reverse overload condition on the reverse backhaul link, wherein the inhibited set of the reverse packets are received from ones of the user devices having a lowest level of reverse packet loss on the reverse RF links.
