Description
The present invention is to distinguish the purpose of use of a femtocell base station, and more particularly, whether a femtocell base station (Home Node B) is a private femtocell base station (Private Home Node B) or a public femtocell base station (Public Home Node B). The present invention relates to a method of distinguishing a femtocell base station for notifying a mobile terminal entering coverage in advance and a femtocell base station applied thereto.
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 center of gravity of the business is shifting to wireless data service.
However, even a system that provides such a high-speed data service has only a few Mbps of channel capacity, and this 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.
In order to solve this problem, according to the development of semiconductor technology, it can be manufactured inexpensively, and it can be installed at home or indoor and used by a few users (about 1 ~ 4), which can reach several Mbps per subscriber in mobile communication systems. Attempts have been made to provide transmission 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 it is possible to provide a wired / wireless communication and home network through IP and a combination of IP by connecting a small base station shaped like a DSL modem to a wired IP network in a home. In addition, since the mobile communication data is transmitted from the base station to the exchange immediately without passing through the indoor repeater, the service provider can reduce the frequency load and improve the call quality while reducing the network construction cost.
In this regard, in case of a femtocell base station (Home Node B) applied to a femtocell, there may be a private femtocell base station (Private Home Node B), in which an individual is installed with the permission of an operator, and the operator removes the shadow area or in a large building. Separately, a public femtocell base station (Public Home Node B) for public users may also be installed at the operator's discretion.
In the case of the personal femtocell base station that the user installs directly, the user group that can access the base station may be limited (when limited to family members only). There is no need to specifically limit who can access B.
More specifically, in the case of a personal femtocell base station, even if a general user possessing a mobile terminal capable of detecting a signal from the base station, if the user does not have access rights to the corresponding personal femtocell base station, to attempt to access the corresponding Home Node B It is unnecessary to try.
That is, when a user who does not have authority to access a specific femtocell base station attempts to connect by detecting a signal of the femtocell base station, not only the load is increased due to the access attempt to the femtocell base station, but also a mobile terminal that attempts to access the battery also consumes battery power. Disadvantages occur.
Therefore, in the case of a personal femtocell base station, before the mobile terminal attempts to access, it is preferable that base station information including information indicating that the base station is a personal femtocell base station and accessible user group information should be transmitted.
However, if a user group needs to be set up in a common femtocell base station like a private femtocell base station, the mobile station needs to transmit the above-described base station information before attempting access, but as the number of users registered in the base station is large, The notifying process may act as an inducing factor in inefficient operation of the base station.
