Abstract

The present invention relates to an apparatus for receiving and distributing GPS signals for positioning a GPS distribution module in front of a GPS receiver to synchronize a base station.
In the present invention, a GPS receiver includes a receiver for receiving GPS signals, a signal distributor for distributing the GPS signals received through the receiver to two or more signals, a gain compensator for amplifying and delivering the distributed first GPS signals from the signal distributor, And a transmitter for transmitting the distributed second GPS signal from the signal distributor to another GPS distribution module.
According to the present invention, it is possible to eliminate the signal interference and distortion when compared to the conventional GPS antenna synchronization, and to save the installation cost of the GPS antenna and simplify installation.
In addition, the synchronization time of the base station is minimized and the stability of the base station is improved compared with the conventional IEEE1588-based synchronization.

Description

[0001] Broadcasting Service Apparatus at a stand-alone LTE e-NodeB [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcasting service method in an LTE base station, and more particularly, to a method for allowing a base station to continuously maintain a broadcasting service when communication between an LTE core network and a base station is lost.

In LTE systems, broadcast services can be supported as specified in the standard.

When the LTE network operates normally, the base station (e-NodeB) can provide a broadcasting service by interworking with the LTE network. In other words, when the LTE network operates normally, the broadcasting service can be provided by receiving broadcasting data from a broadcasting server connected to the LTE network and transmitting the broadcasting data to all terminals connected to the LTE network.

However, if the interworking with the broadcasting server is disconnected due to a disaster, or the connection to the LTE network is disconnected in a worse case, it is impossible to broadcast disaster information to the LTE subscribers by the existing broadcasting server. However, for the safety of the public, broadcasting service that broadcasts disaster information in such a disaster situation becomes more necessary.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide an apparatus for operating a local broadcasting service alone to continue a minimum broadcasting service even when a base station is disconnected from an LTE network.

According to an aspect of the present invention, a wireless communication system in a wireless communication system for providing a broadcasting service may include a broadcasting service apparatus for providing a broadcasting service alone.

Here, the broadcast service apparatus includes an operator connection unit for operator connection and authentication, a voice connection unit for receiving voice broadcast information, a data connection unit for data service such as text broadcast information, and a broadcast connection unit for transmitting broadcast information And a virtual broadcasting server for transmitting the virtual broadcasting server to the terminal.

The voice connection unit may further include a function of encoding a voice signal and converting the voice signal into a Voice over Internet Protocol (VoIP) packet in order to enable voice transmission to the terminal.

According to the present invention, even if disaster broadcasting by the LTE network and the broadcasting server is impossible, the LTE base station alone can perform disaster broadcasting.

2 is a diagram illustrating an LTE base station having a broadcast service apparatus according to an embodiment of the present invention.
3 is a block diagram illustrating a configuration of a broadcast service apparatus 231 according to an embodiment of the present invention.

In the following description, well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the subject matter of the present invention.

Although the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, But should be understood to include all modifications, equivalents, and alternatives.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description with reference to the accompanying drawings, the same or corresponding components will be denoted by the same reference numerals, and redundant description thereof will be omitted.

1 is a diagram illustrating an example of a broadcast service in a normal case.

1, in a normal case, the broadcasting server 120 transmits broadcasting data to the LTE base station 130 through the LTE network 110 for broadcasting service. Then, the LTE base station 130 can implement the broadcasting service by transmitting the broadcasting data to all the connected LTE terminals 140.

However, if a trouble occurs in the broadcasting server itself due to a disaster, or a problem occurs in the LTE network and the interworking between the broadcasting server and the LTE base station is interrupted, the broadcasting service by the broadcasting server may not be possible any more.

2 is a diagram illustrating an LTE base station having a broadcast service apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the LTE base station 230 may include a broadcast service apparatus 231. When the LTE network operates normally, the broadcasting service apparatus of the base station does not operate and the broadcasting service can be provided by the broadcasting server interworking with the LTE network. However, if the connection with the broadcasting server is disconnected due to a disaster or the like, or in a worse case, the connection with the core network is disconnected, the authorized operator operates the broadcasting service apparatus of each base station and notifies the terminal connected to each LTE base station The disaster relief service can be continued.

At this time, the base station may incorporate a voice codec for directly processing voice input.

3 is a block diagram illustrating a configuration of a broadcast service apparatus 231 according to an embodiment of the present invention.

3, the broadcast service apparatus 231 includes an operator connection unit 340 for operator connection and authentication, a voice connection unit 320 for receiving voice broadcast information, a data connection unit 330 for data service such as text broadcast information, And a virtual broadcasting server 310 that replaces the function of the broadcasting server interlocked in normal operation. In particular, the voice connection unit 320 may encode a voice signal and convert the voice signal into a Voice over Internet Protocol (VoIP) packet in order to enable voice transmission to the terminal. The virtual broadcasting server 310 may serve as an application server similar to the broadcasting server.

Although the above description has been made on the LTE network as an example, it will be appreciated that the above method can be similarly applied to a general wireless communication system.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. Only. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
