Definitions
- Femtocell was first proposed by Ubiquisys in the United Kingdom, which stems from the lack of initial coverage of the third-generation communication technology (3rd-generation) and the challenge of WiFi technology.
- 3rd-generation third-generation communication technology
- WiFi WiFi
- Femtocell is in the same standard and same frequency band as other mobile base stations of the operator. Therefore, Femtocell is also versatile for mobile terminals such as mobile phones. In general, the Femtocell has a transmit power of 10 to 100 mW and a coverage radius of approximately 50 to 200 m. It can support 4 to 6 active users and allows the user to move at a maximum speed of approximately 10 km/h. At present, the industry has introduced a newer Femtocell with a lower power.
- the Femtocell is connected to a personal computer (Personal Computer, called "PC") using a Universal Serial Bus (“USB").
- PC Personal Computer
- USB Universal Serial Bus
- a device with broadband uplink capability In use, the user places the phone on the Femtocell connected to the PC, and the user answers the call using the Bluetooth headset.
- Femtocells which are currently used for indoor coverage in homes or office areas, and ultra-low-power Femtocells used abroad are two different types of products. If the Femtocell for home use is carried abroad, the power of the Femtocell is controlled by the home network operator, so that the normal signal of the Femtocell covers the entire indoor range, which necessarily causes some interference to the surrounding local carrier network. . Since the home operator does not have the spectrum resources of the region, the use of the Femtocell poses certain legal risks. Summary of the invention
- FIG. 2 is a schematic diagram of a method of switching an operating mode in accordance with another embodiment of the present invention.
- FIG. 3 is a schematic diagram of a method of switching an operating mode in accordance with still another embodiment of the present invention.
- determining the working mode adopted by the femtocell base station may further include: acquiring mode selection information; and determining an operating mode adopted by the femtocell base station according to the mode selection information.
- the mode selection information includes at least one of local geographic area information, a local IP address, and local carrier information.
- it may be determined whether the femtocell base station is located in a geographical area of the home operator.
- the first working mode may be determined when the femtocell base station is located in a geographical area of the home operator, and the second working mode is adopted when determining that the femtocell base station is located in a geographical area of the non-home operator.
- the Femtocell determines the working mode adopted by the Femtocell according to the local geographic area information in the mode selection information
- the Femtocell supports the Global Positioning System (“GPS) function
- GPS Global Positioning System
- the Femtocell can The local geographic area information of the local area is obtained by using the GPS, and compared with the geographical area information of the home operator stored in the Femtocell or the Subscriber Identity Module (“SIM”), so that the Whether the Femtocell is located in the geographical area of the home carrier.
- SIM Subscriber Identity Module
- controlling the transmit power of the femtocell base station may include: controlling the transmit power of the femtocell base station to be the first power when determining that the femtocell base station adopts the first working mode,
- the transmit power of the femtocell base station is controlled to the first power according to the received dynamic power control information from the network node.
- the determining module 510 may further include:

Abstract
L'invention porte sur un procédé et une station de base femtocellule pour commutation du mode opérationnel. Le procédé consiste à: déterminer un mode opérationnel utilisé par une station de base femtocellule, ledit mode opérationnel comprenant un premier mode opérationnel fonctionnant à une première puissance et un second mode opérationnel fonctionnant à seconde puissance, la seconde puissance étant inférieure à la première; contrôler la puissance de transmission de la station de base femtocellule de telle sorte que ladite station de base femtocellule fonctionne au premier mode ou au second mode opérationnel selon le mode opérationnel déterminé. La station de base femtocellule comprend un module de détermination destiné à déterminer le mode opérationnell que la station de base femtocellule utilise; un module de commande de la puissance destiné à commander la puissance de transmission de la station de base femtocellule selon le mode opérationnel déterminé. Le procédé et la station de base femtocellule de cette invention permettent la commutation libre entre modes opérationnels de la station de base femtocellule avec pour effet d'offrir un choix plus vaste à l'utilisateur et de mieux répondre à ses besoins.
