Embodiment Construction

[0043] Next, an exemplary embodiment of the present invention will be explained with reference to the drawings. First, the following is an explanation of a method of operating an HNB-GW (Home NodeB Gateway) (HNB Gateway Device) with reduced power according to the present invention.

[0044] The method of operating the HNB-GW with reduced power according to the present invention is characterized by enabling the HNB-GW with a low usage rate to be converted to the sleep mode. When the HNB-GW operates in the sleep mode, the HNB-GW deactivates functions other than those required to release the sleep mode.

[0045] The number of UE (User Equipment) registrations is used as an index indicating the utilization rate of HNB-GW. Because UE registration is a standard operation defined in the aforementioned Non-Patent Document 1, the present invention can be implemented without involving changes to the UE and HNB (Home NodeB).

[0046] In order for HNB-GW to obtain or change the list of HNB-GWs...

Abstract

The present invention provides a HNB gateway device capable of deactivating functional units other than those associated with a mode check message and a sleep release request message from another HNB‑Gw when operating in sleep mode, and thereby enabling Power saving operation. The HNB gateway device (2) includes the following functions: obtaining the usage rate of the HNB gateway device, relaying signals between the switching center and the HNB, and switching to a sleep mode when the usage rate reaches a predetermined value or falls below a predetermined value. The HNB gateway device includes: when transitioning to the sleep mode, using RPC from the HMS: setting parameter values, changing the HNB gateway list in the HNB performing HNB registration on the HNB gateway device (HNB list management unit 23) .

Description

Technical field [0001] The present invention relates to an HNB gateway device, a femto cell system, and a method of operating an HNB-GW for a femto cell system with reduced power, and particularly to an HNB (Home NodeB)-GW (gateway) forming a femto cell system Power-saving operation. Background technique [0002] Because the HNB (Home NodeB) forming the aforementioned femtocell system is installed in ordinary homes and offices, the usage rate of HNB and HNB-GW is low according to the time of day. Although there are various studies on methods of operating HNB with reduced power, research on methods of operating HNB-GW with reduced power is still needed. [0003] The femto cell system related to the present invention includes HNB, HNB-GW and HMS (Home NodeB Management System). HNB is a small-range base station installed in homes and offices, and is also referred to as FAP (Femto Access Point). HNB-GW is a device that relays signals between the switching center and HNB. [0004] HMS...
