Problems solved by technology
[0005] A client can select only a favorite service among various provided information to receive it, and in this regard, a method of selectively receiving information based on the location information of the client has not been defined
[0006] In addition, the prior art broadcast / multicast service does not define such a method that the service allows the server to classify multimedia type information or various contents based on the user's location and provide it
[0007] In other words, the problem with the broadcast / multicast service of the prior art is that the same information is simultaneously provided to a plurality of clients and the clients receive the information unconditionally regardless of their locations

Embodiment Construction
[0029] A broadcast / multicast service method based on user location information according to the present invention will now be described with reference to the accompanying drawings.
[0030] The present invention proposes an interface and operation between a terminal providing user's favorite content or information and one or more servers based on user location information. In particular, the present invention proposes a broadcast / multicast service by which a server filters various contents or information based on user location information and provides it to users in a relevant service area. In this case, the server may provide the service to each user in the relevant area, provide the corresponding service to the terminal requesting the service in the corresponding area, or provide the corresponding service to the area requested by the user.
[0031] In the present invention, when a user requests a broadcast / multicast service provided in a specific area, the broadcast / multicas...

In a broadcast / multicast service based on user location information, when a terminal sets contents desired to be received in a specific area, a broadcast / multicast server checks current location information of the terminal transmitted from a location server or from the corresponding terminal, selects contents provided in the corresponding area, and transmits it to the terminal. Thus, a waste of acommunication channel can be prevented, and since a user can selectively receive contents or information according to his / her location, user's satisfaction and convenience can be enhanced.
Description
[0001] This application is a divisional application of the patent application submitted on June 15, 2005 with the application number 200580020035.0 (PCT / KR2005 / 001839) and the title of the invention is "Broadcast / Multicast Service Method Based on User Location Information". technical field [0002] The present invention relates to broadcast / multicast services, in particular to broadcast / multicast services based on user location information. Background technique [0003] Broadcast / multicast services that provide sky-wave broadcasts or various auxiliary information to mobile terminals are a new type of service, including: broadcast services that provide useful information through service providers to all clients that have subscribed to its services; and A multicast service where information is provided only to a defined group of clients that have previously subscribed to a particular topic or content. [0004] Since the broadcast / multicast service can provide the same informat...
