Embodiment Construction

[0043] Some embodiments now contemplated by the claims will now be described more fully hereinafter with reference to the accompanying drawings. However, other embodiments are within the scope of the claims, and the claims should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will serve to The scope of the inventive concept conveys to those skilled in the art. Like numbers refer to like elements throughout the specification.

[0044] It is an aim of certain embodiments disclosed herein to provide for wireless device (hereinafter denoted WD) offloading to so-called sub-optimal cells. A cell may be referred to as suboptimal because, from a WD perspective, one or more characteristics of a signal from a suboptimal cell may be lower or worse than corresponding characteristics of the serving cell. The difference may be such that the WD will not normally use the sub-optimal cell. How...

Abstract

According to certain embodiments, a method for offloading a wireless device (110) is disclosed. The method includes identifying suboptimal cells (140). The suboptimal cell (140) provides a wireless device (110) with a second wireless signal having a first signal characteristic that is less than a corresponding first signal characteristic of a first wireless signal provided by a serving cell (130). The method also includes transferring the wireless device (110) from the serving cell (130) despite a first signal characteristic of a first wireless signal from the serving cell (130) being superior to a first signal characteristic of a second wireless signal from a sub-optimal cell (140). ) offloaded to the suboptimal cell (140).

Description

[0001] priority [0002] This application claims priority to U.S. Provisional Application No. 62 / 145,555, filed April 10, 2015, entitled "Method and Apparatus to Offload Mobile Terminals in Cellular Networks" . technical field [0003] Embodiments set forth herein relate generally to wireless communications, and in particular to methods, network nodes, wireless devices, computer programs or computer program products for offloading wireless devices. Background technique [0004] In a wireless communication system (eg, a cellular communication system such as High Speed ​​Packet Access (HSPA)), the performance of a wireless device is often limited by the level of interference in the cell in which the wireless device operates. The level of interference places a limit on the range of operation of the wireless device with respect to the transmitting network node (eg, a base station such as a NodeB or eNodeB). The operation of the wireless device may also be affected when the tra...
