为了便于本领域一般技术人员理解和实现本发明,现结合附图描绘本发明的实施例。 To facilitate those of ordinary skill in the art understand and implement the present invention, now in conjunction with the accompanying drawings depict embodiments of the present invention.

本发明的基本思想为:首先将设备终端的数据备份到设备管理服务器上。 The basic idea of ​​the invention is as follows: First, the backup data terminal device to the device management server. 所述的数据包括软件程序和设备终端的个性化数据,当设备终端数据丢失或错误时,可以将备份的数据恢复到设备终端。 Said personalization data comprises data terminal equipment and the software program, when a terminal apparatus data loss or errors can restore backed up data to the terminal device. 当终端软件程序错误时,可以自动下载备份的软件,然后安装并配置软件,以完成设备终端的数据和软件恢复。 When the terminal software program error, backup software can automatically download and install and configure the software, and software to perform data recovery device terminal. 所述设备终端包括手机终端、掌上电脑、笔记本电脑、嵌入式设备、车载系统等移动设备。 The terminal apparatus comprises a mobile phone terminals, PDAs, notebook computers, embedded devices, automotive systems and other mobile devices.

下面描述本发明的数据备份方法。 The following data backup method according to the present invention will be described.

如图1所示,在步骤1中,首先在设备终端与设备管理服务器之间建立会话,并确定备份数据。 As shown, in step 1, a first established between the terminal equipment session with the device management server, and the backup data is determined. 建立会话并确定备份数据有三种方法,一是通过UI(用户交互界面),二是通过在终端设定自动触发条件,三是通过其它方式,下面分别描述这三种方法。 Determining the backup data session is established and there are three ways, one by UI (user interface), two trigger conditions are automatically set by the terminal, the third is by other means, the following three methods are described.

下面描述设备终端通过UI发起会话并确定备份数据的过程。 The following describes a terminal device initiates a session through the UI and determines the data backup process. 终端设备通过DM Agent向DM服务器发起操作会话请求,在会话请求中附带Generic Alert(服务请求)来告知服务器终端所请求的备份操作。 Operating the terminal device initiates a session request to the DM server by the DM Agent, incidental Generic Alert (Service Request) in the session request to inform the backup server requested by the terminal. 如果发起请求时确定了将要备份的备份数据,则在Generic Alert中附带备份数据标识(如URI统一资源标识),否则,即Generic Alert没有带备份数据标识,则设备管理服务器与设备终端之间通过交互来确定准备备份的备份数据,确定备份数据的方法可以是:用户通过终端交互界面确定,或者服务器首先获取终端可作为目标数据的数据信息,然后通过下发交互命令将这些数据信息呈现给用户并让用户选择,用户根据交互界面提供的信息确定需要备份的目标数据。 Determine if a request to initiate a backup of data to be backed up, then comes back up data identification (such as URI Uniform Resource Identifier) ​​in the Generic Alert, otherwise, namely Generic Alert did not take the backup data identified through between the device management server and the device terminal the method of interaction is determined backup data preparation backup, determining the backup data may be: a user determined by the terminal interface, or the server first acquires the terminal can be used as data information of the target data, and then present these data to the user via issued interactive command and let the user choose, according to information provided by the user interface to determine the target data to be backed up.

当设备终端需要告知服务器终端请求的操作时,可以通过在会话请求数据包中附带Generic Alert命令来达到此目的。 When the terminal needs to inform the operator of the device requested by the terminal server, the session request can be included in the data packet Generic Alert command for this purpose. Generic Alert命令需要附带一个事先定义好的双方都理解的备份标识,即Alert Type。 Generic Alert command comes back up needs to identify a pre-defined both parties can understand that Alert Type. 如数据存储的Alert Type可以定义为“org.openmobilealliance.dm.backup.userrequest”。 Alert Type The stored data can be defined as "org.openmobilealliance.dm.backup.userrequest".

下面描述终端设定自动触发条件自动发起会话备份数据的过程。 Process conditions for automatically initiating a session data backup terminal set automatically triggered will be described below. 首先在终端设定触发条件,触发条件包括时间条件(如定时、间隔某个时间段等)、事件条件(如数据修改、软件更新等)。 First, in the terminal set trigger conditions, trigger condition comprises a time condition (e.g., a timing, a time interval, etc.), event condition (e.g., data modification, software updates, etc.). 监控程序在监控到触发条件满足时,会首先自动确定需要备份的目标数据,当采用时间条件时,可将所有的数据进行备份,或备份部分数据;当采用事件条件时,如数据修改条件,可仅备份修改的数据。 Monitor while monitoring the trigger condition is met, will first automatically determines the target data to be backed up, when using the temporal condition, all the data can be backed up, or back part of the data; When event condition, such as data modification conditions, You can back up only the modified data. 然后通过DM Agent发起会话请求。 Then initiates a session request by DM Agent. 在会话请求包中附带Generic Alert来告知服务器终端所请求的操作,同时附带备份数据标识(如URI统一资源标识)。 Generic Alert included in the session request packet to inform the operator of the server requested by the terminal, while the backup data included identification (e.g., a uniform resource identifier URI).

下面描述通过其它方式(如Portal(门户)、短消息等)发起会话并确定备份数据过程。 Initiating a session are described below by other means (e.g., Portal (portal), short messages, etc.) and determines the data backup process. 通过其它方式(如Portal、短消息等)通知DM服务器对设备终端备份数据进行备份,设备管理服务器向设备终端发送Notification(通知)以建立会话。 By other means (e.g., Portal, short messages, etc.) to the DM server notifies the terminal device backup data backup device management server transmits the Notification (notification) to the terminal device to establish a session. 如果用户在向DM服务器请求时没有告知DM服务器需要备份的备份数据,则DM服务器与设备终端通过交互来确定准备备份的备份数据,确定方法可以是服务器首先获取终端可作为目标数据的数据信息,然后通过下发交互命令将这些数据信息呈现给用户并让用户选择,用户根据交互界面提供的信息确定需要备份的目标数据。 If the user does not inform the DM server when the request to the DM server backs up data, the DM server and the device terminal determines the backup data are backing up by interaction determination method may be a server first acquires the terminal can be used as data information of the target data, then issued by interactive command data information to the user and allows the user to select the target data user interface based on the information provided to determine the need to back up.

在步骤2中,当设备终端与设备管理服务器建立会话,并确定备份数据后,设备管理服务器可根据设备终端选择的备份数据获得设备终端的备份数据,根据本发明,可以有三种方法获得备份数据,下面描述服务器获取备份数据的方法。 In step 2, when the terminal equipment establishes a session with the device management server, and determine backup data, the device management server may obtain the backup data terminal equipment in accordance with the backup data terminal equipment selection, according to the present invention, there are three ways to obtain the backup data the following describes the backup server to obtain data.

第一种方法,当确定备份数据后,可将备份数据标识(如备份数据的URI)传送到设备管理服务器。 The first method, when the backup data is determined, the identification data can be backed up (backup data such as URI) to the device management server. 确定备份数据可分两种情况:一是设备终端确定的,二是通过设备终端与设备管理服务器确定的。 Determining the backup data can be divided into two situations: First, the terminal device is determined, and second terminal device is determined by the device management server.

当是第一种情况时,设备终端确定的备份数据,设备终端可以通过GenericAlert的<LocURI>将备份数据标识(如URI)发送给设备管理服务器,例如,可通过如下命令将备份数据标识发给设备管理服务器。 When the first case, the equipment terminal determines that the backup data, the device terminal may GenericAlert a & lt; LocURI & gt; backup data identifier (e.g., URI) to the device management server, for example, the following command backup data identifier issued to the device management server. <Alert><CmdID>2</CmdID><Data>1226</Data> <--Generic Alert--><Item> & Lt;; & lt; Alert & gt; & lt; CmdID & gt; 2 & lt; & gt / CmdID Data & gt; 1226 & lt; / Data & gt; & lt; - Generic Alert - & gt; & lt; Item & gt;

<Source><LocURI>./Root</LocURI></Source> & Lt; Source & gt; & lt; LocURI & gt; ./ Root & lt; / LocURI & gt; & lt; / Source & gt;

<Meta> & Lt; Meta & gt;

<Type>org.openmobilealliance.dm.backup.userrequest</Type> & Lt; Type & gt; org.openmobilealliance.dm.backup.userrequest & lt; / Type & gt;

<Format>chr</Format> & Lt; Format & gt; chr & lt; / Format & gt;

</Meta> & Lt; / Meta & gt;

<Data/></Item></Alert> & Lt; Data / & gt; & lt; / Item & gt; & lt; / Alert & gt;

当是第二情况时,由设备终端与服务器交互所确定的备份数据,则通过交互命令对应的<Status>返回选择结果(也就是备份数据标识如URI)给设备管理服务器。 When the second case, the terminal interacts with the server device to the determined backup data, through interactive command corresponding & lt; Status & gt; selection result returned (i.e. back up data such as identification URI) to the device management server.

设备管理服务器在获取目标数据的URI后,可直接通过下发Get命令获取URI指定的目标数据。 After obtaining the device management server URI target data, can be sent directly Get command to get the URI specified by the target data. 数据在传送之前可以进行一些预处理,如压缩、加密等。 Data transfer may be performed before some preprocessing, such as compression and encryption. 例如:<Get> For example: & lt; Get & gt;

<CmdID>4</CmdID> & Lt; CmdID & gt; 4 & lt; / CmdID & gt;

<Item> & Lt; Item & gt;

<Target> & Lt; Target & gt;

<LocURI>./Root</LocURI> & Lt; LocURI & gt; ./ Root & lt; / LocURI & gt;

</Target></Item></Get> & Lt; / Target & gt; & lt; / Item & gt; & lt; / Get & gt;

第二种方法,如图2所示,当设备终端确定备份数据后,设备终端打包数据并存放到设备管理树的单独节点上,以便设备管理服务器获取数据包。 The second method, shown in Figure 2, the terminal device determines when the backup data, the data terminal equipment packed into individual node devices exist in the management tree, the device management server in order to obtain a data packet. 为了实现本方法,首先在DM管理树上增加一个存储备份数据的节点Outbox。 To implement the method, a first increase Outbox nodes storing backup data in the DM management tree. Outbox节点为设备终端和设备管理服务器提供了一个数据传输的通道,当设备终端确定了存储的备份数据后,设备终端会对备份数据进行打包,并将备份数据包存放到Outbox节点上。 Outbox node provides a data transmission channel for the terminal device and device management server, the terminal device determines when the backup data stored in the terminal device will backup data package and to store the backup data packets on node Outbox. 服务器直接通过命令Get获得这个节点的数据。 Get server directly to obtain the data for this node command.

第三种方法,当设备终端确定需要存储的备份数据后,设备终端对备份数据进行打包,然后直接上传给服务器,上传使用Generic Alert命令。 The third method, when the terminal device determines the need to store the backup data, the backup data to the terminal device is packaged, and then uploaded to the server, using the Generic Alert command to upload. 例如:<Alert><CmdID>2</CmdID><Data>1226</Data> <--Generic Alert--><Item> For example: & lt; & lt;; & lt;; Alert & gt; & lt; CmdID & gt; 2 & lt; & gt / CmdID Data & gt; 1226 & lt; & gt / Data - Generic Alert - & gt; & lt; Item & gt;

<Source><LocURI>./Root</LocURI></Source> & Lt; Source & gt; & lt; LocURI & gt; ./ Root & lt; / LocURI & gt; & lt; / Source & gt;

<Meta> & Lt; Meta & gt;

<Type>org.openmobilealliance.dm.backup.userrequest</Type> & Lt; Type & gt; org.openmobilealliance.dm.backup.userrequest & lt; / Type & gt;

<Format>chr</Format> & Lt; Format & gt; chr & lt; / Format & gt;

</Meta> & Lt; / Meta & gt;

<Data> & Lt; Data & gt;

<CDATA>...</CDATA><--Upload data--> & Lt; CDATA & gt; ... & lt; & lt;; & gt / CDATA - Upload data - & gt;

</Data></Item></Alert> & Gt / Data;; & lt & lt; / Item & gt; & lt; / Alert & gt;

在步骤3中,DM服务器存储获得的备份数据。 In Step 3, the DM server stores the backup data obtained. 根据本发明,如图3所示,数据包可以以树的方式进行组织:树有两个子树,分别存储终端管理树和非管理树上的数据。 According to the invention, shown in Figure 3, data packets can be organized in a tree manner: tree has two sub-tree, the terminal management tree of the management tree and the non-data are stored. 如果是管理树上的数据,树的组织按终端管理树的结构进行组织;对于非管理树上的数据,按其在终端侧的路径组织。 If the management tree data organization is organized in a tree structure of the terminal management tree; data for non-management tree, its path at the terminal side of the tissue.

最后设备管理服务器存储获得的备份数据。 Finally, the device management server backup data storage available. 备份数据在设备管理服务器上以树的形式存储。 Backup data stored in the form of a tree in the device management server. 将备份数据存储在树上,存储的方法如下,首先在树上查找备份数据,如果找到,则对其进行更新,如果没有,则在树上增加存储该备份数据的结点。 The tree, the following backup method for storing data storage, data backup first look at the tree, if found, update it, and if not, increase the storage nodes in the tree of the backup data.

为了减少备份数据时的通信量,可以采取一定的措施,如在终端侧设定一些识别标志,使得每次只发送确定的备份数据中经过修改的部分,而不是全部备份数据。 To reduce the amount of communication data backup, you can take certain measures, such as the identification number set in the terminal side, so that each modified portion only transmits the determined backup data, rather than the entire backup data.

下面介绍数据恢复方法,在需要备份数据时,可通过Portal、短消息等方式通知DM服务器,或设备终端直接发起会话,利用Generic Alert通知服务器,以便DM服务器进行数据的恢复。 The following describes a data recovery method, when the data to be backed up, the DM server may be notified through the Portal, short messages, etc., or directly to the terminal equipment initiates a session by Generic Alert notification server DM server for data recovery. 如果是Portal或短消息方式通知DM服务器,则DM服务器会向设备终端发送Notification(通知)以触发会话建立流程。 If a short message notification Portal or DM server, the DM server sends the Notification (notification) to the terminal equipment to trigger a session establishment procedure. 如果在向DM服务器请求时没有DM服务器需要操作的目标数据,则需要在建立会话之后进行DM服务器和设备终端的交互来确定准备操作的目标数据,确定方法可以是服务器首先获取备份数据的信息,然后通过下发交互命令将这些数据信息呈现给用户并让用户选择,用户根据交互界面提供的信息确定需要恢复的目标数据。 If there is no target data DM server to be operated upon a request to the DM server, you need to interact with the DM server and the device terminal after establishing the session to determine the target data preparation operations, the determination method may be a server first acquires information backup data, then issued by interactive command data information to the user and let the user choose the user interface data based on objective information provided to determine the need to recover. 在确定目标数据后,DM服务器提取备份数据树上的数据并恢复到终端。 After determining the target data, DM server extracts the data backup and restore data tree to the terminal. 备份数据可以使用Replace命令或其它命令。 Back up data using a Replace command or other commands.

当设备终端需要告知服务器终端请求的操作时,可以通过在会话请求数据包中附带Generic Alert命令来达到此目的。 When the terminal needs to inform the operator of the device requested by the terminal server, the session request can be included in the data packet Generic Alert command for this purpose. Generic Alert命令需要附带一个事先定义好的双方都理解的恢复标识,即Alert Type。 Generic Alert command comes with a pre-defined need both parties can understand restores identity, namely Alert Type. 如数据恢复的Alert Type可以定义为“org.openmobilealliance.dm.restore.userrequest”。 Such as data recovery Alert Type can be defined as "org.openmobilealliance.dm.restore.userrequest".

根据本发明,优选地,在数据备份过程中,当备份的数据为程序数据时,可以只备份程序数据的标识、版本号;在数据恢复过程中,DMS可根据程序数据标识和版本号控制设备终端对该程序数据进行下载、安装和配置。 According to the present invention, preferably, the data backup process, when the backup data is program data, back up only identification, version number of the program data; the data recovery process, the DMS may be a control apparatus according to a program data identifier and version number terminal to download, install and configure the program data.
