Abstract

PURPOSE: A method and a system for supplying a broadcast/multicast service by considering time or an area in a mobile communication system are provided to enable a mobile communication system to decide contents related to a specific area where a subscriber is included or related to contents necessary at a specific time, thereby preventing unnecessary contents from being provided. CONSTITUTION: A contents provider decides whether the content of contents data is updated(S400). If so, a BCMCS contents server receives the contents data from the provider(S402). The BCMCS contents server generates a broadcast message including a time field where the contents data is to be broadcasted(S404), and compares the time field with a current time(S406). If the current time is included in the range of the time field, the generated broadcast message is broadcasted to a BCMCS terminal(S408).

Description

Method and System for Providing Broadcast / Multicast Services Considering Time or Location by Using Mobile Telecommunication System}

The present invention relates to a method and a system for providing a broadcast / multicast service in consideration of time or region in a mobile communication system, and more particularly, to providing a broadcast / multicast service to a mobile subscriber. The present invention relates to a method and system for determining and providing necessary content or content related to a specific region to which a subscriber belongs.

Recently, due to the development of mobile communication technology, the services provided by the code division multiple access (CDMA) mobile communication system are not only voice services, but also circuit data and packets. It is developing into a multimedia communication service for transmitting data such as data. In addition, to support the multimedia communication service to the maximum, a broadcast / multicast service that provides a service to a plurality of terminals from one data source is emerging.

1 is a diagram schematically illustrating a form of providing a multimedia communication service.

FIG. 1A is a diagram illustrating a unicast form of a multimedia communication service providing form. The unicast form is a form applied to Transmission Control Protocol (TCP), in which frame transmission is performed only between two hosts.

1B is a diagram illustrating a broadcast form of a multimedia communication service providing form. The broadcast type is a type applied to the User Datagram Protocol (UDP), in which a host transmits a frame to all hosts on a cable.

1C is a diagram illustrating a multicast form of a multimedia communication service providing form. The multicast form is applied to the User Datagram Protocol (UDP). In a user connected to a local area network (LAN) or the Internet, a host transmits a frame to a plurality of hosts and receives a plurality of hosts. The information is propagated by transmitting the same content to a plurality of hosts in a bucket relay manner. That is, the multicast type transmits a frame only to a plurality of specific hosts, unlike a unicast type transmitting a frame to a specific host or a broadcast type transmitting a frame to an unspecified host.

The broadcast / multicast service using the broadcast form and the multicast form supports multimedia forms such as video, still images, voice, and text in real time, unlike the cell broadcast service (CBS), which is a message-oriented service. It is a multimedia-oriented service. In addition, the broadcast / multicast service provides multimedia data including streaming data, text data, voice data, etc. to a plurality of users through one link, and eliminates repeated transmission of the same information in a wireless section.

The broadcast service using the broadcast form and the multicast service using the multicast form can be regarded as the same concept from the viewpoint of being performed in a wireless network. However, if you distinguish between broadcast and multicast services from a different perspective, the multicast service user group is a service with limited membership. To be a member of a specific user group, you must subscribe and information is provided only to subscribed members. Can be seen as. On the other hand, a broadcast service is a service that transmits information at a boundary of a specific region (such as a cell or a sector unit), for example, a traffic information providing service of a specific region, and is divided into public and private services according to the nature of the service information. Lose.

For the broadcast / multicast service, a mobile communication system allocates a separate channel or slot and transmits audio data and video data so that a plurality of subscribers can simultaneously receive multimedia contents. . Such broadcast / multicast services are being standardized in 3GPP2.

Currently, broadcast / multicast services that transmit to one subscriber through a single channel have a large part of the service implementation, which can be used to provide video on demand (VOD), location information, and traffic information. The service is being provided. Many of these services, however, contain mostly information that is needed only at certain times. For example, in the case of a traffic information service, the information provided by this service is necessary only during the time when traffic jams occur, and is not otherwise required. In other words, if the traffic information can be provided only during the time when traffic jams occur, it means that it is not necessary to receive traffic information at other times. In addition, the traffic information required by the subscriber only needs the traffic information of the surrounding area where the current subscriber is located, not the area far from the subscriber, and the traffic information other than the adjacent area may be viewed as unnecessary information unless there is a specific purpose. However, there is a problem that providing traffic information unilaterally without considering such a situation is an inefficient service.

Accordingly, the service provider itself needs to provide information on the time and location required by subscribers by deviating from the passive existing service method in which subscribers select one-sided services and receive necessary information. have.

4 is a flowchart illustrating a process of providing a broadcast / multicast service in consideration of time in a mobile communication system according to a first embodiment of the present invention.

First, the content provider 214 determines whether the content data content to be provided is updated (S400). If the content data content has been updated, the BCMCS content server 208 receives the content data from the content provider 214 (S402). Next, the BCMCS content server 208 generates a broadcast message including a time field in which content data is to be broadcast in the received content data (S404). At this time, when the broadcast / multicast service is a security service, the broadcast message is encrypted and generated using the above-described method. In addition, the time at which the content data is broadcast is set by the controller (not shown) of the BCMCS content server 208 according to the content of the content. Next, the time field of the generated broadcast message is compared with the current time (S406).

If the content of the content data is not updated, the process of receiving the content data and the process of generating the broadcast message are unnecessary. Therefore, the process varies depending on whether the content data is updated. This process is repeated when providing a broadcast / multicast service considering the broadcast time.

5 is a flowchart illustrating a process of providing a broadcast / multicast service for each base station in a mobile communication system according to a second embodiment of the present invention.

First, the content provider determines whether the content data content to be provided is updated (S500). If the content data content is updated, the BCMCS content server receives the content data from the content provider (S502). Next, the BCMCS content server generates a broadcast message including a base station code field in which content data is to be broadcast in the received content data (S504). At this time, when the broadcast / multicast service is a security service, the broadcast message is encrypted and generated using the above-described method. In addition, the base station of the region where the content data is to be broadcast is set by the control unit of the BCMCS content server according to the content. Next, after determining whether it is a base station transmitter corresponding to the base station code field (S506), a broadcast message generated only to the base station transmitter matching the data of the base station code field is broadcasted through a broadcast dedicated channel of the wireless communication network (S508). . If the content of the content data is not updated, the process of receiving the content data and the process of generating the broadcast message are unnecessary. Therefore, the process varies depending on whether the content data is updated. This process is repeated as long as the broadcast / multicast service is provided for each base station.

6 is a flowchart illustrating a process of providing a broadcast / multicast service in consideration of a region in a mobile communication system according to a third embodiment of the present invention.

First, the content provider 214 determines whether the content data content to be provided is updated (S600). The BCMCS content server 304 receives content data from the content provider 214 (S602). Next, the BCMCS content server 304 generates a broadcast message including a region field in which the content data is to be broadcast in the received content data (S604). At this time, when the broadcast / multicast service is a security service, the broadcast message is encrypted and generated using the above-described method. In addition, the area where the content data is to be broadcast is set by the controller (not shown) of the BCMCS content server 304 according to the content. Next, the location field of the generated broadcast message is compared with the location coordinates of the BCMCS terminal 300 (S606). In this case, the location coordinates may be the current location of the BCMCS terminal 300 using GPS, or may be location coordinates using address information of a subscriber transmitted from the BCMCS controller 212. As a result of the comparison, when the location coordinates are included in the range of the area field, the generated broadcast message is broadcasted to the BCMCS terminal 300 through a broadcast dedicated channel of the wireless communication network (S608).

FIG. 7 is a flowchart illustrating a process of providing a broadcast / multicast service in consideration of a region for each base station in a mobile communication system according to a fourth embodiment of the present invention.

First, the content provider determines whether the content data content to be provided is updated (S700). The BCMCS content server receives content data from the content provider (S702). Next, the BCMCS content server generates a broadcast message including a base station code field in which content data is to be broadcast and a region field in which the content data is to be broadcast (S704). At this time, when the broadcast / multicast service is a security service, the broadcast message is encrypted and generated using the above-described method. In addition, the base station and region where the content data is to be broadcast are set by the controller of the BCMCS content server according to the content. Next, the BCMCS content server broadcasts a broadcast message to the packet data service node to which the base station transmitter corresponding to the base station code field is connected (S706). Next, the base station controller receiving the broadcast message through the packet data service node compares the area field of the received broadcast message with the position coordinates of the base station transmitter (S708). As a result of the comparison, when the location coordinate is included in the range of the area field, the generated broadcast message is broadcasted to the corresponding base station transmitter through a broadcast dedicated channel of the wireless communication network (S710). This process is repeated as long as the broadcast / multicast service is provided considering the region of each base station.

When the broadcast / multicast service ends, the BCMCS terminals 200 and 300 transition to the standby state just before the broadcast / multicast service. In addition, the broadcast / multicast service is characterized in that simultaneously provided to more than one BCMCS terminal (200 and 300).

Meanwhile, the broadcast / multicast service according to the second, third, and fourth preferred embodiments of the present invention does not process handoff at the base station controller, but instead of the neighbor system transmitted from the mobile communication system. The determination is made so that the terminal handles the soft handoff by itself. Therefore, since the range of regions required for each content is different, the information of neighboring systems transmitted by the mobile communication system is different for each content.

The above description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains may various modifications without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments.
