DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter cellular broadcast system (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
The invention relates to a cellular broadcast system (10) for realizing content broadcast to devices that exist at a determined geographical region. Said content broadcast describes a notification or message which shall be sent to devices that exist in a region where natural disasters particularly like fire, flood, earthquake, landslide, avalanche, storm, whirlwind, etc. occur or emergency conditions like war, terrorism and similar occur. The cellular broadcast system (10) can also provide broadcasting of contents of enterprises for the purpose of informing, advertisement or presentation.
Cellular broadcast system (10) comprises base stations (170) for realizing broadcast to the devices that exist at a specific region. Said base stations (170) have been assigned for providing service to the predetermined geographical region. Base stations (170) comprise antennas for taking and transmitting radio signals. The coverage area of each base station is described as a cell. Said cells describe the region which remains in the coverage area of the base station.
The cellular broadcast system (10) comprises at least one base station controller (160) for controlling assignment of the frequency channels of base stations (170). Said base station controller (160) controls the radio network of one or more base stations. The cellular broadcast system (10) comprises a central broadcast controller (100) for controlling a content broadcast to the devices, which exist at predetermined geographical region, by means of the base station controller (160). Said central broadcast controller (100) transmits a signal related to broadcast to the base station controllers (160). The signal related to said broadcast comprises a target region information. Said target region describes the region where the content will be broadcasted. In a possible embodiment, the central broadcast controller (100) transmits the content broadcast signal to the determined base station controllers (160) based on target region information. The base station controllers (160) which receive the transmitted signal transmits this to the determined base stations (170) depending on the target region information. Base stations (170) which receive the sent signal transfer the content broadcast to the devices that exist in the coverage area. Here, the devices that exist within the coverage area describe the devices that are in connection with the base station.
The cellular broadcast system (10) comprises a content creator (140) for providing realization of content broadcast by a user. Said content creator (140) has been configured to provide selection of a target geographical region and formation of said content broadcast. The access of said user to the central broadcast controller (100) by means of the content creator (140) is controlled by means of a broadcast control unit (110). Said broadcast control unit (110) controls the access level of the user. In this manner, the authorization of a user for realizing content broadcast is controlled by means of the broadcast control unit (110). Thus, the unauthorized users are prevented from occupying radio channels, and the speed of transmission of an emergency content broadcast to the devices that exist in the target region is increased. In a possible embodiment, the content creator (140) is configured to provide a time information, related to content broadcast, to the broadcast control unit (110). In this embodiment, the broadcast control unit (110) has been configured to broadcast the related content broadcast in the related time by means of the central broadcast controller (100). In this manner, the content broadcast is transferred to the devices, provided in the target region, on time.
The central broadcast controller (100) is associated with a database (120) including the predetermined target geographical regions and predetermined content broadcasts. Said database (120) comprises the information of base station which exists in the cellular broadcast system (10) and the information of base station controllers (160) associated with base stations (170) and the information of coverage area information of base stations (170). The database (120) also comprises the content broadcasts which have the predefined target region and content. The user can realize a content broadcast, which has the predefined content and/or target region, by means of the content creator (140). In this manner, the content creation (140) speed of the user is increased and thus, the speed of transmitting of an emergency information to the devices of the persons who exist in the region is increased.
The central broadcast controller (100) is associated with a mobile operator database (130) comprising the data related to cellular broadcast networks of the mobile operators who already give cellular broadcast service. In this manner, the central broadcast controller (100) accesses the information related to cellular networks of operators who realize cellular broadcast. The central broadcast controller (100) is configured to send a request related to the content broadcast to the operators who realize cellular broadcast by means of the mobile operator database (130). In a possible embodiment, the central broadcast controller (100) is configured to transmit a request, which is related to the content broadcast, to the operators who realize cellular broadcast by means of the mobile operator database (130) if the central broadcast controller (100) does not include base stations (170) in a manner realizing broadcast to the target region of the content broadcast.
In a possible embodiment of the invention, the cellular broadcast system (10) comprises an emergency notification device (150) which provides the region and emergency information related to the emergency that occurs at a specific region. Said emergency notification device (150) is configured to transmit the region and emergency information to the broadcast control unit (110). The emergency notification device (150) can be a system which detects the events that occur in a predetermined region or regions. The emergency notification device (150) can be a device which generates signal related to emergency conditions which occur at a specific region and which belong to government or non-governmental organizations. In an exemplary embodiment, the emergency notification device (150) can be a device which draws data from the database of the system which has a seismic network.
