Preferred Embodiments

[26] Consider now a method for providing broadcast / multicast service based on user location data in accordance with the present invention with reference to the accompanying drawings.

[27] The present invention proposes an interface between a terminal providing user-preferred content or information and one or more servers based on the location information of the user, as well as how it works. In particular, the present invention provides a broadcast / multicast service in which a server filters various contents or information based on user location data and provides them to users in respective service areas. In this case, the server can provide a service to each user in the corresponding zone, provide the corresponding service to the terminal that requests the service in the corresponding zone, or deliver the corresponding service to the zone requested by the user.

[28] In the present invention, when a user requests a broadcast / multicast service provided in a specific area, the broadcast / multicast server checks the location information of the user and provides content or information of the corresponding area. In this case, the broadcast / multicast server checks the user’s location data using the location server or checks the user’s location information transmitted from the terminal.

[29] FIG. 1 is a structural block diagram of a broadcast / multicast service system in accordance with the present invention.

[30] As shown in FIG. 1, the broadcast / multicast service system includes an information provider 10, a broadcast / multicast server 30 that checks the area information from the contents and information received from the information provider 10, and provides the contents and information to the corresponding zone through the broadcast / multicast service, terminal 50, which receives content and information from the broadcast / multicast server and transmits the information entered by the user, as well as the location server 20, which checks the location data of the terminal 50. In this case, the information provider 10 can simultaneously deliver one or more content to one or more terminals using broadcast / multicast service.

[31] The terminal 50 includes a broadcast / multicast subscriber unit receiving or requesting a broadcast / multicast service, and a location subscriber unit receiving or requesting location information of a corresponding terminal. In this case, the broadcast / multicast subscriber module and the location subscriber module are modules installed in the terminal.

[32] A broadcast network for actually transferring content and information between the terminal and the broadcast / multicast server provides the following services: the multimedia broadcast / multicast service "MBMS" of the 3GPP system, the broadcast / multicast service "BCMCS" of the 3GPP2 system, or the service Broadcast digital video information - “DVB”. The specified system as a whole is called a broadcast distribution system - "BDS".

[33] For the MBMS and BCMCS services, both uplink and downlink channels are used, so communication between the broadcast / multicast service server and the terminal in the same broadcast network is possible. However, only the downlink is used for the DVB service, therefore, if it is assumed that the terminal will communicate with the broadcast / multicast server, it should be connected to a mobile communication network, for example, high-speed data transmission EV-DO or a global mobile communication system "GSM" to use the uplink.

[34] The system described above operates as follows.

[35] The broadcast / multicast server receives the content from the information provider and stores it. When the broadcast / multicast server receives information about the current location of the terminal from the location server or from the terminal requesting the corresponding content, it transmits the content to be transmitted to the corresponding area from among the contents stored in the memory to the user terminal.

[36] The broadcast / multicast server receives certain contents from the information provider, classifies them and stores them in the corresponding service area, receives information about the current location of the terminal from the location server or terminal requesting the corresponding contents, and transmits the contents intended for the corresponding area, to the user terminal.

[37] Although the broadcast / multicast server does not receive a service request from the terminal, it can provide content and information in accordance with the current location of the terminal, and can transmit content intended for a specific zone requested by the user to the corresponding terminal regardless of information about the current location of the terminal requesting the service.

[38] FIGS. 2 and 3 are a signal flow diagram illustrating a method for providing broadcast / multicast service based on user location information, in which a broadcast / multicast service can be provided through a terminal in which a broadcast / multicast subscriber unit and a subscriber unit the location module can be connected to the same broadcast network. In this case, the network is a network of type “MBMS” of the 3GPP system or “BCMCS” of the 3GPP2 system.

[39] FIG. 2 is a signaling diagram for a method of providing broadcast / multicast services in accordance with a first embodiment of the present invention, where a broadcast / multicast server that is assigned to transmit content or information related to location data directly receives location information of the corresponding terminal from the location server.

[40] As shown in FIG. 2, the broadcast / multicast service providing system includes an information provider 10, a location server 20, a broadcast / multicast server 30, a terminal 50, and an end user 60 that checks the contents and information provided to the terminal 50, and enters certain information. Content and information are transmitted to the terminal 50 via the BDS broadcast distribution system 40. The terminal 50 includes a “BDS” broadcast distribution system receiver 51, a broadcast / multicast subscriber unit and a location subscriber module 53. In this case, since the broadcast / multicast subscriber unit and the location subscriber unit of the terminal 50 are connected to the same broadcast network, two subscriber modules are considered as one object, namely, as a subscriber module 53 broadcast / multicast services (A Bondent module “B / L”).

[41] The broadcast / multicast server 30 receives one or more content from the information provider 10 (step S11). The content includes information about the zone into which the corresponding content is planned to be transmitted, i.e. information about the zone into which relevant content can be provided.

[42] Upon receiving the content, the broadcast / multicast server 30 generates a service menu using data on the service time, location (location) and the corresponding schedule for the delivery of each content, and transmits each service menu to the terminals 50 of each zone in which the broadcast / multicast service. In this case, the broadcast / multicast server 30 may store the contents received from the information provider in two ways. In the first method, content is received and stored, and in the second method, information about the area contained in the content is checked and the content corresponding to each service area is stored in accordance with the classification. The service menu contains a complete list of contents that can be provided by the broadcast / multicast server, or a list of contents that the user has requested in advance or which is selectively compiled based on the preference information registered when the user subscribed to the service.

[43] In the case where each program or content from the service menu contains information about a zone, condition information related to a feature distinguishing a particular zone, location-based content, and service characteristics defining each content

[44] For example, a sign for determining a specific zone contains the name of the zone, detailed address, postal code, exact location coordinates, etc., the content contains classification information, namely, whether the relevant content is an announcement, weather information, etc. p., service characteristics contain information about how the relevant content is delivered - only once or periodically, whether it is delivered when the terminal enters or leaves a specific zone. Let us describe in more detail the information included in the service menu entry.

[45] When the terminal 50 receives the service menu through the “BDS” receiver 51 of the broadcast distribution system 40, it displays the service menu on the display through the broadcast / multicast subscriber unit 53 so that the user 60 can check the service menu (step S13).

[46] The user 60 checks several programs and contents displayed in the service menu entries and selects from all displayed contents a service menu entry corresponding to the contents that it is desired to receive at a particular location or in a place where it is (step S14). Then, the broadcast / multicast service request message is transmitted to the broadcast / multicast service server 30 through the broadcast / multicast subscriber unit 53. In this case, the message requesting the broadcast / multicast service contains information about the content selected by the user and service characteristics, for example, how the corresponding content is delivered - once or periodically, or the content is delivered when the terminal enters or leaves a specific zone, and ID of the terminal. Information about the content may include information about the area in which the relevant content is provided.

[47] When the broadcast / multicast service server 30 receives the broadcast / multicast service request message from the broadcast / multicast subscriber unit 53, it transmits a location request message to the location server 20 (step S16).

[48] Upon receiving the location request, the location server 20 checks whether the location information of the corresponding terminal can be disclosed (for example, this means that the corresponding terminal is set to allow a third party to perform location determination of that specific terminal, otherwise referred to as “Privacy check” (step S17)), and if user permission is required for determining the location, the location server 20 transmits a notification message to the relative But the location permissions to the user 60, and the user transmits a message in response to the notification message (step S18).

[49] A location determination of the terminal is performed between the location server 20 and the location subscriber unit 53 (step S19). Positioning can be performed using the existing positioning method defined in the 3GPP system or 3GPP2 system, or by using the "SUPL" method - determining the location of a secure user plane.

[50] The location server 20 transmits the values of the calculated location coordinates in the response message to the location request message to the broadcast / multicast server 30 (step S20), and the broadcast / multicast server 30 transmits only contents corresponding to the coordinates of the current location from user-selected content via the BDS distribution system 40 to the terminal 50 (step S21). In this case, the contents include the location coordinates of the corresponding terminal.

[51] In the process of transmitting content by the broadcast / multicast service server 30, in the case where the contents received from the information provider 10 are classified and stored in accordance with each service area, the contents of the corresponding service area are transmitted to the terminal 50, then when the received contents are stored as is the case, and the contents that can be provided to the corresponding service area from among all the stored contents are transmitted to the terminal 50.

[52] The contents are transmitted to the broadcast / multicast subscriber unit 53 via the “BDS” receiver 51 of the broadcast distribution system (step S21), and the broadcast / multicast subscriber unit 53 provides the corresponding contents for verification by the user (step S22).

[53] Figure 4 presents the items included in the service manual in accordance with the present invention.

[54] The items shown in FIG. 4 are optionally added to indicate relevant area information when a list of contents including area information is transmitted.

[55] Of these items, the "broadcast zone" indicates the inclusion of information about the zone for transmitting content in the broadcast / multicast mode and contains as the sub-items "target_area" - the target zone or "hor_acc".

[56] The target zone “target_area” sub-item is a sub-item that characterizes the party for which the content is delivered, and contains sub-items such as “shape”, “cc”, “name_area” or “zip_code”. The “hor_ace” sub-item indicates the broadcasting area on the map with a certain accuracy, and, for example, is used to specify a specific area on the electronic map.

[57] The “shape” subparagraph is used to indicate the geographic shape, the “her” subparagraph is a 1-3-digit country code, the name_area subparagraph indicates the name of the region, and the zip_code subparagraph is the zone code assigned to each zone in accordance with postal code number.

[58] The broadcast / multicast service server 30 may divide the content delivery service area using the indicated items. For example, when it is specific to provide a service in a particular city, the broadcast / multicast server 30 may include sub-items "broadcast_area", "target_area" and "name_area = specific city" in the list of relevant content.

[59] Additional elements are used not only to indicate the available coverage area of the content list in the generated service menu, but also to limit the area to which each content list is transferred or to which the content is transferred.

[60] The location request message that the broadcast / multicast server 30 transmits to the location server 20, and the response message to the location request message that the location server 20 transmits to the broadcast / multicast server 30 can be recorded in XML (extensible markup language) by using each factor and attribute defined in the specification "MLP" - a protocol for determining the location of mobile devices STV.

[61] In FIG. 5 to 7 and 8 to 14, a location request message and a corresponding response message are recorded in XML (Extensible Markup Language). In FIG. 5 to 7 illustrate in more detail embodiments of messages used for a single location, and FIG. 8 to 14 show in more detail embodiments of messages used to determine a location periodically or to determine a location when a specific event occurs.

[62] In particular, FIG. 5 shows a conventional one-time location request message corresponding to a location request message that contains an identifier of a location requesting terminal ID, location accuracy data containing time delay data, and accuracy in space, data on the type of location coordinates and setting the priority level.

[63] FIG. 6 shows an “ACK” message, an acknowledgment of receipt for a conventional request for a one-time location determination, which may contain a resulting value, for example, whether the location determination is successful.

[64] FIG. 7 shows a response message to a conventional one-time location request that contains only location coordinates.

[65] FIG. 8 shows a message requesting to periodically determine a location, and FIG. 9 shows a message requesting a location when a specific event occurs, for example, when a terminal enters or leaves a particular zone.

[66] The location message contains the ID of the terminal requesting the location, indicating whether the location is determined periodically or in the event of a specific event, data on the frequency of location requests, its start and end times in the case of periodic location, event characteristics (for example, whether the terminal enters a specific zone, leaves or is located inside it), as well as the name or exact location coordinates in uchae occurrence of a specific event. The location request message contains location accuracy data including time delay and spatial accuracy values, such as location coordinates and priority level settings.

[67] Figures 10 and 11 show ACK messages — an acknowledgment for a periodic location request or a location request in the case of a specific event, namely, an embodiment is shown for the case where the response to the location request can be issued, and for the case when the response to the location request cannot be issued.

[68] FIG. 12 shows location values transmitted as a response message to a periodic location request, or a location request in case of a specific event.

[69] FIG. 13 shows a cancellation message with respect to a periodic location request or a location request in case of a specific event, and FIG. 14 shows an “ACK” message — acknowledgment of receipt for a minimum message.

[70] In particular, the broadcast / multicast server 30 transmits a location request message, a periodic location request message, or a location request message in case of a particular event in accordance with the content characteristics to the location server 20, selected by user.

[71] In order for the broadcast / multicast service server 30 to transmit only the contents corresponding to the location coordinates, it is necessary to perform a procedure of comparing data for each content received from the information provider 10 and the terminal data.

[72] Fig. 15 shows a search table from the database of the broadcast / multicast service server 30, which contains service area elements, a list of contents transmitted to each service area, an identifier of a terminal subscribed to the service, user input data.

[73] For example, a terminal with the identifier “A1” is set to receive content: announcements, weather data, information on the availability of goods, but not content related to fashion. Further, if the location coordinates of the terminal correspond to zone “A”, the broadcast / multicast server transmits content: announcements, weather data and security information, but does not transmit content related to the mod. In this case, the service area can be limited by adding, such an element of information about the zone, which, for example, as optionally shown in figure 4, to the content transmitted to the zone "A".

[74] FIG. 3 is a signaling diagram for a broadcast / multicast service providing method in accordance with a second embodiment of the present invention, in which a broadcast / multicast server transmitting content related to area information receives location information of a specific terminal from this terminal (user).

[75] The broadcast / multicast service server 30 receives one or more content from the information provider 10 (step S31), generates a service menu using the service time, service position, and content transfer schedule, and then transmits the service menu to the terminals 50 of each zone, where the broadcast / multicast service is provided through the BDS broadcast distribution system 40 (step S32). In this case, the broadcast / multicast service server 30 may check the area information contained in the content, classify the corresponding contents by the service areas and save them in this way or save the corresponding contents without classification. The service menu includes a complete list of contents that can be provided by the broadcast / multicast server 30, or contains a list of contents selected depending on preference information previously requested by the user or registered when the user subscribed to this service.

[76] Having received, through the “BDS” receiver 51 of the broadcast service distribution system, the terminal 50 displays the service menu on the display through the subscriber module 53 (broadcast service / location) so that the user 60 can check the service menu (step S33).

[77] When the user 60 selects the content that he wants to receive at a specific location or at his current location from among the contents in the service menu displayed on the display (step S34), the broadcast / multicast service request message is transmitted to the broadcast / server 30 multicast service through the subscriber module 53 (broadcast service / location) (step S35). In this case, the message requesting the broadcast / multicast service contains information about the zone in which the content selected by the user is provided.

[78] The subscriber module 53 (broadcast service / location) transmits a message requesting a location to the server 20 location, as well as a message requesting a broadcast / multicast service (step S36). In this case, the location request message is sent in a one-time location request message format, a periodic location request message, or a location request message when a specific event occurs.

[79] Upon receiving the location request message, the location server 20 calculates the location coordinates by using the existing location method or the “SUPL” method of determining the location of the secure user plane (step S37), includes the location coordinates in the response message to the request message about location and then transmits it to the subscriber module 53 (broadcast service / location) of the corresponding terminal (w ag S38).

[80] After receiving the response message, the subscriber module 53 (broadcast service / location) transmits the location coordinates to the server 30 broadcast / multicast service (step S39), and the server 30 broadcast / multicast service transmits only the contents corresponding to the coordinates of the location, from among the contents selected by the user to the terminal 50 via the BDS broadcast distribution system (step S40). In this case, the contents include the location coordinates of the corresponding terminal. In this case, when the broadcast / multicast service server 30 classifies the contents received from the information provider 10 by zones and stores it in this way, it transfers the contents of the corresponding service area to the terminal 50, whereas if the broadcast / multicast server 30 stores the contents without classifying the service area, it transfers the contents of the corresponding service area to the terminal 50 from the number of stored contents.

[81] Content transmitted to the subscriber module 53 (broadcast service / location) through the "BDS" receiver 51 of the broadcast distribution system are issued to the user for verification (step S41).

[82] FIG. 16 is a signal flow diagram for a broadcast / multicast service providing method in accordance with a third embodiment of the present invention, and FIG. 17 is a signal flow diagram for a broadcast / multicast service providing method in accordance with a fourth embodiment of the present an invention showing the implementation of a broadcast / multicast service through a terminal in which the subscriber module is wide The broadcast / multicast service and the subscriber location module cannot be connected to the same broadcast network. In this case, the broadcast / multicast service is received through the digital video information broadcasting system “DVB” while the request for location information is transmitted via the 3GPP system or the 3GPP2 system. Since the digital video information broadcasting system “DVB” contains only one downlink without an interactive channel, the location information is transmitted via the uplink of the network allocated in the 3GPP system and 3GPP2 system.

[83] As shown in FIGS. 16 and 17, a terminal 150 receiving a broadcast / multicast service via a network 140, broadcasting digital video information “DVB” comprises a “DVB” digital video broadcast broadcast receiver 151 receiving a subscriber unit 153 (Subscriber “B / M” module) of broadcast / multicast service, mobile subscriber module 155 (Subscriber module “M”) for transmitting a location request message to the broadcast / multicast service server 130 to the location server 120 and user 160. That is, the receiving subscriber module 153 of the broadcast / multicast service operates as a dedicated receiving subscriber module, and the mobile subscriber module 155 operates as a dedicated transmitting subscriber module for transmitting specific information, except for information about the current the location of the corresponding terminal to the broadcast / multicast server 130.

[84] Consider now with reference to FIG. 16 a method for providing broadcast / multicast services in the case where the broadcast / multicast server 130 for transmitting content related to the area information directly receives location data of the corresponding terminal 150 from the server 120 location.

[85] When the broadcast / multicast service server 130 receives one or more content from the information provider 110 (step S51), it generates a service menu using the service time, service position, and content transfer schedule, and then through the broadcast distribution system 40 - The “BDS” transmits a service menu to the terminals 150 of each zone where the broadcast / multicast service is provided (step S52). In this case, the broadcast / multicast service server 130 may check the area information contained in the contents, classify the corresponding contents by the service areas, and save them in this way or save the corresponding contents without classification. The service menu includes a complete list of contents that can be transmitted by the broadcast / multicast service server 130, or contains a list of contents selected depending on preference information previously requested by the user or registered when the user subscribed to this service.

[86] The service menu received through the “BDS” receiver 51 of the broadcast distribution system is displayed on the display through the receiving subscriber broadcast / multicast subscriber unit 153 for verification by the user (step S53).

[87] When the user 160 selects the content that he wants to receive at his current location or at a specific location from the contents of the services menu displayed on the display (step S54), the mobile subscriber module 155 transmits a broadcast / multicast service request message to the server 130 broadcast / multicast services (step S35). In this case, the message requesting the broadcast / multicast service may contain information about the zone into which the content selected by the user is provided.

[88] After receiving the broadcast / multicast service request message, the broadcast / multicast server 130 transmits a location request message to the location server 120 (step S56), and the location server 120 checks whether the location data of the corresponding terminal can be disclosed 150 (step S57). If user permission is required for the location, the location server 120 transmits a notification message to the user 160 to resolve the location, and then receives a response message (step S58). In this case, the location request message is sent in a one-time location request message format, a periodic location request message, or a location request message when a specific event occurs.

[89] The location server 120 calculates the location coordinates using the existing location method or the “SUPL” method for determining the location of the protected user plane (step S59), and transmits the location coordinates in a response message to the location request message to the broadcast / server 130 multicast service (step S60).

[90] The broadcast / multicast server 130 transmits only content corresponding to the location coordinates from the number of contents selected by the user to the terminal 150 via the DVB digital video broadcast system 140 (step S61), and the receiving subscriber broadcast / multicast module 153 the service receives and issues contents (step S62).

[91] Here, in the case where the broadcast / multicast service server 130 classifies the contents received from the information provider 110 by zones and stores them in this way, it transfers the contents of the corresponding service area to the terminal 150, whereas if the broadcast / server 130 the multicast service stores content without classifying the service area; it transmits the contents of the corresponding service area to the terminal 150 from among the stored contents.

[92] Consider now with reference to FIG. 17 a method for providing broadcast / multicast service in a case where a broadcast / multicast service server that transmits contents related to the area information directly receives location data of the corresponding terminal 150 from the terminal.

[93] When the broadcast / multicast service server 130 receives one or more content from the information provider 110 (step S71), it generates a service menu using the service time data, the service position and the content transfer schedule, and then through the BDS broadcast distribution system 40 "Transmits a service menu to the terminals 150 of each zone where the broadcast / multicast service is provided (step S72). In this case, the broadcast / multicast service server 130 may check the area information in the content, classify the corresponding contents by the service areas and save them in this way or save the corresponding contents without classification. The service menu includes a complete list of contents that can be transmitted by the broadcast / multicast server 130, and a list of contents selected depending on the preference information previously requested by the user or registered when the user subscribed to this service.

[94] The service menu is received by the receiving subscriber broadcast / multicast subscriber module 153 via a “DVB” digital video broadcast broadcast receiver 151 of the terminal 150, and the receiving subscriber broadcast / multicast subscriber module 153 displays it on the display to the user 160 for verification (step S73).

[95] When the user 160 selects from a service instruction a record of the contents that he wishes to receive at his current location or at a specific location (step S74), the mobile subscriber unit 155 transmits a broadcast / multicast service request message to the broadcast / multicast server 130 service (step S75), as well as a message requesting the location to the location server 120 (step S76). In this case, the broadcast / multicast request message and the location request message are transmitted to the broadcast / multicast service server 130 and the location server 120 via the uplink of the 3GPP system or 3GPP2 system, but not through the DVB digital video broadcast network 140 "

[96] After receiving the location request message, the location server 120 calculates the location coordinates by using the existing location method or the “SUPL” method of determining the location of the secure user plane (step S77), includes the location coordinates in the response message to the request message about determining the location and then transmitting it to the mobile subscriber module 155 of the corresponding terminal 150 (step S78).

[97] After receiving the response message, the mobile subscriber broadcast / multicast module 155 transmits the location coordinates to the broadcast / multicast server 130 (step S79), and the broadcast / multicast server 130 transmits only the contents corresponding to the location coordinates from among the contents that can be transmitted to the corresponding terminal, to the terminal 150 via the BDS broadcasting distribution system 140 (step S80). In this case, the contents include the location coordinates of the corresponding terminal. In this example, if the broadcast / multicast service server 130 classifies the content received from the information provider 110 into zones and stores them in this way, then it transfers the contents of the corresponding service area to the terminal 150, whereas if the broadcast / server 130 the multicast service stores contents without classification by service areas, it transfers the contents of the corresponding service area to the terminal 150 from among the stored contents.

[98] After receiving the contents via the DVB broadcast digital video information receiver 151, the subscriber broadcast / multicast service module 153 outputs the contents (step S81).

[99] In this embodiment of the present invention, when a broadcast / multicast server receives a response for specific content from a terminal, it provides corresponding contents to the terminal. However, in this regard, although the broadcast / multicast server does not receive a content request from the terminal, it can check the location of the terminal through the location server to selectively transmit content in accordance with the current location of the terminal, or it can transmit the content requested by the user, regardless current location of the terminal.

[100] For example, when the broadcast / multicast server 30 receives content from the information provider 10, it can check a terminal located in a specific area through the location server 20 and transmit content that can be provided to the corresponding area to terminals 50 located inside this zone.

[101] Furthermore, when the broadcast / multicast service server 30 receives the content from the information provider 10, it can classify and store the content according to the service area by using the area information from the content and then, when the terminal requests the content of the specific area, the server 30 the broadcast / multicast service transmits the contents of the corresponding zone to the terminal 50.

[102] The above-described method for providing broadcast / multicast service based on location data in accordance with the present invention has several advantages.

[103] For example, since predetermined information or contents are delivered selectively depending on the location information of the user, unnecessary loading of the communication channel can be prevented.

[104] In addition, since the user selectively receives content or information according to its current location, the user may receive additional services benefits.

[105] The foregoing embodiments of the present invention and their advantages are provided by way of example and do not limit the present invention. The present invention can be applied to other types of devices. The description of the present invention is illustrative and does not limit the scope of the claims. It will be apparent to those skilled in the art that other variations, modifications, and changes associated with the invention are possible. The following additional claims are intended to encompass the structures described herein as performing these functions, not only as structural equivalents, but also equivalent structures.
