Abstract

A system for downloading firmware to a mobile terminal by using a broadcast service is provided to use a relatively small bandwidth and shorten transmission time by transmitting a firmware update package to a plurality of mobile terminals through a broadcast channel at the same time. An SP(Service Provider) generates and provides the firmware update package. A DM(Device Management) server receives management of an interaction network by downloading firmware update. An OMA(Open Mobile Alliance) DM downloads the firmware through the broadcast channel by receiving the firmware update package through OMA file delivery and receives the management of a one-way broadcast distribution system. DM clients download the firmware update package at the same time by connecting to the broadcast channel. The firmware update package is encrypted and distributed by a mechanism defined in the OMA file delivery. The management of the network and the system fixes a delivery path of the firmware update package.

도 2는 본 발명에 의한 브로드 캐스트 채널(Broadcast Channel)을 이용한 펌웨어 다운로드 시스템을 나타낸 흐름도. 2 is a flowchart illustrating a firmware download system using a broadcast channel according to the present invention.

본 발명은 이동통신 단말기에 관한 것으로, 특히 브로드캐스트 서비스를 이용한 단말기 펌웨어 다운로드 시스템 및 방법에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to a terminal firmware download system and method using a broadcast service.

도 1은 종래 기술에 의한 쌍방향 채널(Interactive Channel)을 이용한 펌웨어 다운로드 시스템을 나타낸 흐름도이다.1 is a flowchart illustrating a firmware download system using an interactive channel according to the prior art.

종래의 네트워크 오퍼레이션(Network Operation)은 서비스 제공자(Service provider), DM(Device Management)서버 및 DM(Device Management) 클라이언트로 구성된다. DM(Device Management) 클라이언트인 단말기(Terminal)은 쌍방향 채널(Interactive Channel)을 통해 DM 서버와 접속하여 펌웨어 업데이트 패키지를 수신 하고 단말기에 다운로드 후 다시 DM 서버에 결과를 통보한다. DM 서버는 서비스 제공자(Service provider)로부터 펌웨어 업데이트 패키지를 제공받아 단말기로 전송한다. 이러한 방식은 하나의 단말기에 대해서만 업데이트 패키지를 보낼 수 있었다. 이는 다수 단말기의 동일 펌웨어 업데이트가 필요 시 단말기 수만큼의 쌍방향 채널이 요구됨으로 넓은 대역폭(Bandwith)이 소요되고, 업데이트 패키지를 각 단말기로 전송해야하므로 긴 시간이 소요되는 문제점이 있다. The conventional network operation is composed of a service provider, a device management (DM) server, and a device management (DM) client. The terminal, which is a DM (Device Management) client, connects to the DM server through an interactive channel to receive a firmware update package, downloads it to the terminal, and notifies the DM server of the result. The DM server receives the firmware update package from the service provider and transmits it to the terminal. This approach could only send update packages to one terminal. This requires a wide bandwidth (Bandwith) as the number of two-way channel is required when the same firmware update of the plurality of terminals is required, it takes a long time because the update package must be transmitted to each terminal.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 브로드캐스트 채널을 이용하여 다수의 단말기에 펌웨어 업데이트 패키지를 제공하여 전송시간을 줄이는데 그 목적이 있다. The present invention has been made to solve the above problems, and an object thereof is to reduce a transmission time by providing a firmware update package to a plurality of terminals using a broadcast channel.

상기의 목적을 달성하기 위한 본 발명은 펌웨어 업데이트 패키지(Firmware update package)를 생성하여 제공하는 서비스 제공자(Service provider); 상기 펌웨어 업데이트를 다운로드하여 양방향 채널의 Interaction Network의 management를 제공받는 DM 서버; 상기 펌웨어 업데이트 패키지를 OMA file Delivery로 수신하여 브로드 캐스트 채널로 펌웨어 다운로드하고 단방향 브로드 캐스트 분배 시스템의 Management를 제공받는 OMA(Open Mobile Alliance) DM; 상기 브로드캐스트 채널에 접속하여 펌웨어 업데이트 패키지를 동시에 다운로드 하는 DM 클라이언트를 포함하여 이루어진다. The present invention for achieving the above object is a service provider for generating and providing a firmware update package (Firmware update package) (Service provider); A DM server receiving the management of the Interaction Network of the bidirectional channel by downloading the firmware update; An Open Mobile Alliance (OMA) DM that receives the firmware update package as an OMA file delivery, downloads the firmware to a broadcast channel, and provides management of a unidirectional broadcast distribution system; And a DM client accessing the broadcast channel and simultaneously downloading a firmware update package.

이하 본 발명의 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명한 다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 의한 브로드 캐스트 채널(Broadcast Channel)을 이용한 펌웨어 다운로드 시스템을 나타낸 흐름도이다. 2 is a flowchart illustrating a firmware download system using a broadcast channel according to the present invention.

본 발명에 의한 네트워크 오퍼레이션(Network Operation)은 서비스 제공자(Service provider), DM(Device Management)서버, OMA(Open Mobile Alliance) DM 및 DM(Device Management) 클라이언트로 구성된다. 서비스 제공자(Service provider)는 펌웨어 업데이트 패키지(Firmware update package)를 생성하여 제공한다. DM 서버는 서비스 제공자로부터 단말기 펌웨어 다운로드 및 양방향 채널의 Interaction Network의 management를 제공받고 OMA(Open Mobile Alliance) DM으로 펌웨어 업데이트 패키지를 OMA file Delivery로 전송한다. DM 클라이언트인 단말기는 브로드 캐스트 채널로 단말기 펌웨어 다운로드와 단방향 브로드 캐스트 분배 시스템의 Management를 제공받는다. 네트워크 및 시스템의 management는 펌웨어 업데이트 패키지의 전송 경로를 지정한다. 이때, 펌웨어 업데이트 패키지(Firmware update package)는 OMA 파일 전송을 위한 정의된 매커니즘에 따라 암호화되어 분배된다. 모바일 브로드캐스트(Mobile broadcast) 전송을 이용해 다수의 단말기가 접속하여 동일 펌웨어 업데이트 패키지를 수신한다.The network operation according to the present invention includes a service provider, a device management (DM) server, an open mobile alliance (OMA) DM, and a device management (DM) client. The service provider creates and provides a firmware update package. The DM server receives the terminal firmware download from the service provider and management of the interactive network of the bidirectional channel, and transmits the firmware update package to the OMA file delivery to the Open Mobile Alliance (OMA) DM. The DM client terminal is provided with the terminal's firmware download and management of the one-way broadcast distribution system through the broadcast channel. Management of the network and system specify the transmission path of the firmware update package. At this time, the firmware update package is encrypted and distributed according to a defined mechanism for OMA file transfer. Mobile broadcast transmission allows multiple terminals to access and receive the same firmware update package.

본 발명은 브로드캐스트 채널을 이용하여 다수의 단말기에 펌웨어 업데이트 패키지를 동시 전송할 수 있기 때문에 상대적으로 적은 대역폭이 사용되고, 전송시간도 짧아지는 효과가 있다. In the present invention, since a firmware update package can be simultaneously transmitted to a plurality of terminals using a broadcast channel, a relatively low bandwidth is used and a transmission time is also shortened.
