Description

FemtoCell Base Station, Mobile Station and Play Station for Multimedia Service and Multimedia Service System using FemtoCell Base Station}

The present invention relates to a femtocell base station, a mobile communication terminal and a playback device for a multimedia service, and a multimedia service system using a femtocell base station, and more particularly, to a femtocell for a multimedia service for playing back multimedia data provided from a femtocell base station in a playback device. A multimedia service system using a base station, a mobile communication terminal and a playback device, and a femtocell base station.

A femtocell is a combination of femto (one hundred thousand trillion trillion) and a cell (cell), which is a unit of service area for one base station in mobile communication, and covers a smaller area than the existing mobile service radius. Say. The scope of a home is within the range of mobile communication services, and the femtocell base station that looks like a DSL modem is connected to a wired IP network to provide a wired / wireless communication through a mobile phone and a combined service with a home network to provide a wireless communication environment. do.

Conventional mobile communication services have been focused on voice service-oriented business models, but recently, various high-speed data service systems such as HSDPA and Mobile WiMAX have emerged, and the center of gravity of the business has shifted to wireless data services. However, even a system providing 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. Do. Therefore, users who have experienced tens of Mbps speeds of wired and wireless LANs are falling significantly in terms of satisfaction.

As a solution to this problem, attempts have been made to provide a transmission capacity of several Mbps per subscriber in a mobile communication system by installing a small base station such as a femtocell base station at home or indoors and being used by a small number of users.

Since the femtocell base station is located in the service area of a macro radius macro base station that is located outdoors, the femtocell base station should be configured to avoid interference with the macro cell base station during the initial setting process.

However, since femtocell base stations are likely to be located in homes, including general homes or offices, it is difficult to record information about their location, and even if they are set at the time of femtocell installation, the information of neighboring base stations is known or measured. It is inconvenient to grasp the surrounding information.

In addition, the femtocell base station is one of the alternatives to solve the shadow area of the mobile communication service, there is an advantage that can be utilized as an indoor communication infrastructure for wired and wireless convergence service. However, in the femtocell mobile communication service environment, it is impossible to completely limit the radio wave reaching distance of the femtocell base station only to the home where the base station is installed, and the base station radio wave inevitably reaches the neighboring house.

Accordingly, a problem arises in that a neighboring mobile communication terminal can use a mobile communication service using a femtocell base station, and the radio waves of a WLAN access point (AP) installed in a home are transmitted to the neighboring house, A similar problem arises when a computer can connect to a WLAN access point.

There is no problem for a user that allows an external mobile communication terminal or computer to access a femtocell base station or a wireless LAN access point installed in a home and use a communication service, but there may be a user who does not want to use the femtocell mobile communication service.
