Abstract: An idle mode load balancing capability enables balancing of idle mode wireless devices across wireless carriers in order to ensure that the possibility of congestion on any given wireless carrier is reduced or even minimized when idle mode wireless devices become active. The idle mode load balancing may be performed for wireless carriers by determining relative numbers of idle mode wireless devices on the wireless carriers and performing idle mode load balancing for the wireless carriers based on the relative numbers of idle mode wireless devices on the wireless carriers. The relative number of idle mode wireless devices on a wireless carrier may be determined based on a change in load on the wireless carrier during the observation period, which may be determined based on an observed change in load on the wireless carrier and a load correction associated with session terminations on the wireless carrier.

Abstract: The method includes receiving, at a network element, a media data packet sent from a first source user equipment (UE) towards a first destination UE; detecting, at the network element, congestion in at least one of a downlink channel between the network element and the first destination UE, and an uplink channel between the first source UE and the network element; identifying a second source UE that is transmitting first data to a second destination UE through the network element and has a subscriber priority level lower than the first source UE if the detecting detects congestion; sending a congestion indication that causes the second source UE to lower a rate at which the second source UE transmits the first data through the network element to the second destination UE if the detecting detects congestion; and sending the media data packet from the network element to the first destination UE.

Abstract: A policy and charging rules function (PCRF) includes an input port, a processor, and an output port. The input port receives near-real-time network state data. The processor makes optimization decisions based upon the near-real-time network state data. The processor also produces policy enforcement messages based upon the optimization decisions. The PCRF transmits the policy enforcement message via the output port.

Abstract: A method for performing load balancing in a wireless network. Operating conditions are determined in the wireless network. Network policies are dynamically adjusted based upon the operating conditions. Users are offloaded from an overloaded site to another site based upon the operating conditions.
