Systems and Methods For Selecting a Network Access System

摘要

A system according to some embodiments of the invention includes (1) a component (e.g. ANDSF) that provides a cell selection rule to a UE and (2) a component (e.g. an access node) that provides the UE with information about the load in the cell currently utilized by the UE. This enables the UE to determine whether to leave the cell, which may be a 3GPP cell, and use a different cell, which may be a non-3GPP cell, by applying the cell selection rule in conjunction with its knowledge about the load of the cell.

1. A method for load balancing in a user equipment (UE), the method comprising:
receiving at a UE a message comprising a cell selection rule, wherein the cell selection rule comprises:
a selection condition, wherein the selection condition indicates one or more conditions under which the cell selection rule is to be applied; anda selection instruction, wherein the selection instruction indicates an order of cells; receiving at the UE a cell preference indicator (CPI) value transmitted from an access node, wherein the CPI value indicates a load associated with a first cell; determining, based on the received CPI value, whether the selection condition is satisfied; in response to determining the selection condition is satisfied, selecting one of the first cell and a second cell based on the order indicated by the selection instruction; and connecting to the selected cell.
