Apparatus and method for accessing broadcast / multicast service of mobile communication}

The present invention relates to a method and apparatus for accessing a mobile communication broadcast service. In particular, a method for accessing a mobile communication broadcast service enabling a customer to widely select desired broadcast service contents by linking a broadcast service that can be provided in a mobile communication network with an LBS. And to an apparatus.

With the development of the current communication technology, not only the satellite broadcasting service (satellite DMB) has been provided, but also the mobile communication network technology has been improved to enable the broadcasting service through the mobile terminal.

In the existing mobile communication technology (IS-95, CDMA2000 1x, etc.), there was a limit in providing broadcast services due to the limitations of the technology. In other words, the conventional technology has a problem in that many users can not be accommodated at once due to bandwidth limitations because different users are assigned different radio and RP channels.

Here, the RP channel refers to a channel from an access network (AN) to packet data serving nodes (hereinafter, referred to as “PDSN”). This RP channel is assigned to each customer by the Point-to-Point Protocol (PPP) setting between the mobile station (MS) and the PDSN, and an Internet Group Management Protocol (IGMP) message is transmitted from the PDSN. Register the group for multicast in the router, receive the message to receive from the broadcasting server, and transmit it to each customer.

Accordingly, the broadcast service currently being performed in the mobile communication network is to provide a broadcast service regardless of the number of customers while minimizing network resources required by the broadcast service by setting up a channel for a separate broadcast service. In a synchronous network, a broadcast service is implemented through BCMCS (Broadcast / Multicast Service) centering on 1xEV-DO / EV-DV and in asynchronous network, a MBMS centering on wideband CDMA (WCDMA). Among them, the BCMCS which is actively progressing around 1xEV-DO is briefly described as follows.

BCMCS (Broadcast / Multicast Service) is a service that provides the same information (multimedia including streaming, text message, voice, etc.) to multiple users through one link, and eliminates repeated transmission of the same information in a wireless section. . BCMCS has been discussed as the carriers of each country that have built the 1xEV-DO network have argued for the need for BCMCS in the 1xEV-DO system, and standardization is taking place. The service can be provided according to the system and terminal development. According to the characteristics of a mobile communication network, all base stations can broadcast simultaneously with the same contents, and each base station can broadcast with separate contents according to a specific environment and setting of each region. Of course, the MBMS provided by WCDMA is the same.

On the other hand, Location Based Service (“LBS”), which provides various services based on location information, is also continuously being developed. In the past, it was difficult to provide LBS to customers in In-Building where satellite signals did not reach or signal strength was weak.However, the development of GPS-based terminal technology and accurate location-based services in In-Building With the efforts of mobile operators to provide, it is possible to provide accurate locations to customers in In-Building, through which various contents based on location can be provided.

An object of the present invention is to provide a broadcast service contents broadcast in all base stations and special broadcast service contents in a region where the customer is located in correspondence with the location information of the customer to the customer who wants the broadcast service together, The present invention provides a method of accessing a mobile communication broadcast service that allows a customer to select a desired broadcast service content by linking a broadcast service provided by the LBS with an LBS.

The present invention relates to a method for accessing a mobile communication broadcast service of a system consisting of a mobile terminal, a broadcast service server, and a location-based service server, and the present invention relates to at least one of the present invention. A first step of a mobile terminal accessing the broadcast service server and requesting a content list; A second step of performing authentication on the connected mobile terminal and requesting the location information service server from the mobile terminal when the authentication is completed; A third step of calculating a location of a mobile terminal in the location based service server and responding to the broadcast service server; And a fourth step of searching for broadcast service contents broadcasted by all base stations in the broadcast service server and broadcast service contents proceeding only at the location of the mobile terminal and transmitting the searched list to the mobile terminal. do.

After the fourth step, a fifth step of receiving a broadcast by tuning to a broadcast channel corresponding to the broadcast service identifier in response to the list selection of the mobile terminal is further performed. At this time, the broadcast service identifier is a broadcast service identifier and a multicast IP address and a source IP address which are permitted to use the mobile terminal by the authentication, or PDSN is used for the broadcast service identifier, the multicast IP address and the source IP address. Table identifier for searching in database.

In the fourth step, a list of broadcast service contents is determined according to paid or free broadcast service content information.

On the other hand, another object of the present invention, by informing the customer who wants a broadcast service with the broadcast service contents broadcast in all base stations and the special broadcast service content in the region where the customer is located in response to the location information of the customer In addition, the present invention provides a mobile communication broadcast service access device that allows a customer to select a desired broadcast service content by linking a broadcast service that can be provided in a mobile communication network with an LBS.
