A femtocell operating system and method for providing a wireless bridge function for sharing.

Existing mobile communication service has been progressed based on voice service-oriented business model. However, with the advent of various high-speed data service systems such as HSDPA and Mobile WiMAX, the weight of the wireless data service underline business is shifting.

However, even a system that provides such a high-speed data service has a channel capacity of only several Mbps, and the channel capacity is shared by hundreds of users located within base station coverage, and thus the available download speed per person is only tens to hundreds of Kbps. . Therefore, users who have experienced tens of Mbps speeds of wired and wireless LANs are greatly reduced in terms of satisfaction.

As a solution to this problem, it can be manufactured inexpensively according to the development of semiconductor technology, and it can be installed at home or indoor and used by a few users (around 1 ~ 4), so that the transmission of several Mbps per subscriber even in a mobile communication system Attempts have been made to provide capacity.

In this regard, recently, a femtocell, which is a personal base station installed indoors and serving 1 to 4 subscribers, has been proposed. The femtocell is a combination of femto, which represents one-tenth of a trillion (10 to 15 squared), and a cell, which represents a unit of a service area in charge of one base station in mobile communication. It refers to a service that covers an area much smaller than the service radius, and connects a micro base station, which looks like a DSL modem, to a wired IP network in a home, thereby allowing free use of wired and wireless communication with a mobile phone. In addition, since mobile communication data is transmitted from the base station to the exchange immediately, rather than through an indoor repeater, the operator can reduce the network construction cost, improve the frequency load and improve the call quality, and also provide high-speed Internet services such as Wi-Fi as well as voice calls. Can provide.

The main sites where femtocells will be installed and operated are expected to be homes and small offices. Considering the purpose of use, output, size, etc., it is more likely to be installed in the living room in the house for proper coverage formation and ease of installation operation, and more likely to be installed on the wall inside the office in the office. These femtocells are likely to be used in large quantities in the tens of thousands to hundreds of thousands, considering the low cost of 100,000 ~ 200,000 won and the various advantages of femtocells.

However, the backhaul cost is pointed out as one of the biggest obstacles of such femtocell service.
