Wake-up of a femto base station from sleep mode and handover

By introducing monitoring equipment and controller modules into microcell base stations, the transmitter module is only activated within the coverage area of ​​cellular mobile phone devices, which solves the problems of high power consumption and interference of traditional microcell base stations and achieves more efficient services and lower costs. The effect of radiation.

Problems solved by technology

In this configuration, femtocells typically consume a lot of power, which is unreasonable if this is the application
The constant transmission of BCH and pilot associated with these traditional femtocells also results in considerable power consumption
High power consumption makes widespread deployment of traditional femtocells relatively inefficient

Abstract

How to activate a femto cell being in a power save mode. The femto cell continuously receive the uplink signal of mobile terminals in its vicinity on the RACH, e.g. a call set-up, and if the signal quality is better than the one of the macro cell base station or the delay indicates that the mobile terminal is close enough to the femto base station the femto base station initiates a call handover. The femto base station receives the timing on the RACH by receiving the BCH of the macro base station. The mobile terminal may also send a dedicated signal to wake up the femto cell base station. A femtocell for conserving power, which includes a transmitter module configured to be inactive for periods of call inactivity and data inactivity within a corresponding femtocell geographic coverage area, and includes a monitoring device configured to monitor the femtocell geographic coverage area, and further includes a controller module configured to cause a call handover to the femtocell when a cellular handset device is functioning and is located within the femtocell geographic coverage area. The femtocell also being configured to communicate with one or more macrocell base stations, each having a corresponding macrocell, which are configured to facilitate communication between the cellular handset device and a wireless network.

Description

[0001] Cross reference of related applications [0002] This application claims the rights and interests of U.S. Provisional Patent Application No. 61 / 548,662 filed on October 18, 2011 and U.S. Patent Application No. 13 / 517,898 filed on June 14 and 2012, all of which are incorporated by reference. Here. Technical field [0003] The present invention generally relates to a small-scale base station (femtocell), and more specifically relates to the realization of a green microcell base station. Background technique [0004] Microcell base stations are small-scale base stations that are usually installed and designed by users to enhance cellular services in buildings. Micro cell base stations are usually used in mobile phone networks and usually cover a smaller area than traditional cellular macro cells. Microcell base stations allow service providers to expand service coverage and enhance indoor capacity (capacity), as well as other areas where access is limited or unavailable. Howe...
