Abstract
Systems and methodologies are described that facilitate camping load balancing utilizing a frequency attribute. In a tracking area update procedure, each tracking area confirmed to user equipment can include an attribute of preferred, non-preferred, or forbidden. Based on such attribute, the user equipment can camp or idle on a particular cell for a specific frequency or network. The user equipment can camp on a cell from a preferred tracking area unless the quality of cells from the preferred frequency or network drops under a minimum threshold. The systems and methodologies provide a unified framework for camping load balancing across different Radio Access Technologies (RATs) and an optimization for the relevant signaling.
Claims64
A method that facilitates managing camping load balancing for at least one user equipment in a wireless communication system, comprising:
- locating a user equipment within the wireless communication system with a network request, from a network node;
- receiving an attribute of a tracking area location for the user equipment according to the network request;
- identifying the attribute as at least one of a preferred frequency, a non-preferred frequency, or a forbidden frequency;
- selecting between one or more frequencies to utilize for communication based at least in part upon the attribute of the tracking area location, wherein the selecting between one or more frequency includes switching from a frequency corresponding to a tracking area having the preferred frequency attribute to a frequency corresponding to a tracking area having the non-preferred frequency attribute when a quality condition drops below a threshold condition, wherein the threshold condition is a S-criteria threshold;
- and
- transmitting, from the network node, a camping instruction for the user equipment to camp in a cell on the selected frequency.
