Problems solved by technology

A 4G network that includes 4G cells that communicate wirelessly with user equipment (called UEs) may consume a significant amount of power, which is wasteful if no UEs are using the 4G service provided by the 4G cells of the 4G network

Embodiment Construction

[0027] In some geographic areas, multiple networks exist, including 4G. For example, in certain geographic areas, 3G networks or 2G and 4G networks may be accessed wirelessly. In this case, 4G network can be called overlay network and 3G or 2G network can be called underlay network, this is because 3G / 2G network can provide wide coverage and 4G coverage is sporadically deployed on top of 3G / 2G coverage within a part of the While some services, such as video chat or gaming, can only be accessed over 4G networks, other services can perform adequately using sub-4G service levels. For example, text messages, phone calls or web browsing can be adequately handled using 3G or 2G networks.

[0028] If the UE's unit is capable of using multiple networks utilizing different wireless technologies (such as 3G and 4G, or 2G, 3G and 4G), the cell the UE is communicating with can indicate to the UE's unit that when the service requested by the UE does not require the use of 4G When connec...

Abstract

Various arrangements for managing wireless network communication are described. Two cells using different radio access technologies (RATs), such as a 3G cell and a 4G cell, may provide overlapping coverage. A first cell using a first RAT, under certain circumstances, may be permitted to enter a powered down state such that less power is consumed. User equipment may communicate with the cell using the second RAT as the preferred network and only communicate with the cell using the first RAT when a service available through the first RAT but not the second RAT has been requested. Upon a request from the second cell, the first cell may enter a powered up state.

This application also claims priority to US Application No. 61 / 327,784, filed April 26, 2010, entitled "System and Method for Network Energy Saving." This application also claims priority to US Application No. 61 / 317,273, filed March 24, 2010, entitled "Network Energy Saving Scheme." All three applications are hereby incorporated by reference for all purposes. Background technique [0003] Advanced cellular networks, such as those based on the LTE standard (Long Term Evolution, the standard used by some "4G" networks), are being deployed across the country and around the world. 4G networks allow user equipment, such as cellular phones including smartphones, laptops, and tablets, to execute data-intensive applications. A 4G network comprising 4G cells that communicate wirele...
