具体实施方式 Detailed ways

[0019] 本发明实施例提供一种终端切换业务运营商的方法,本发明实施例还提供相应的终端和系统。 Embodiment provides a method for terminal service operator handover [0019] the present invention, the embodiment of the present invention also provides a corresponding terminal and system. 以下分别进行详细说明。 The following are described in detail.

[0020] 实施例一、请参阅图1,本发明实施例中终端切换业务运营商的方法一个实施例包括: [0020] Embodiment 1 Referring to FIG 1, one embodiment includes a method of switching a terminal service embodiments of the present invention the operator:

[0021 ] 101、从切换管理服务器获取运营商的服务器信息。 [0021] 101, to obtain information from the operator's server switching management server.

[0022] 用户使用终端从SP处获取服务时,可能会需要更换SP。 [0022] the user terminal to obtain service from the SP, SP may need to be replaced. 例如,当用户发现无法正常连接当前提供业务的SP时(例如,终端的运营商业务信息或者DRM信息被损坏,简明起见,本文将当前提供业务的SP称为第二运营商SP2),或者当用户希望从SP2切换到另一个运营商(简明起见,本文将用户希望切换到的SP称为第一运营商SPl)以便访问不同的IPTV业务时,该用户会操作终端来选择运营商,由终端根据用户的选择来执行切换。 For example, when a user finds not connect the current SP providing the service (e.g., service operator information or DRM information of the terminal is damaged, the sake of brevity, the current provided herein referred to as second service operator SP with SP2), or when when the user wishes to switch from SP2 to another operator (the sake of simplicity, herein the user wishes to switch to a first called the SP carrier SPl) to access different IPTV service, the user may select operating terminal operator, by a terminal switching is performed according to a user selection. 例如,当终端是机顶盒时,用户可以通过机顶盒的遥控器或者机顶盒上的切换按钮来选择运营商;当终端为手机时,可通过手机自身的键盘或触摸屏幕上的虚拟键盘来选择运营商。 For example, when the terminal is a set top box, the user may select a carrier by the switching button on the STB remote control or set-top box; when the terminal is a mobile phone, may be selected operator via the virtual keyboard on the phone itself keypad or a touch screen.

[0023] 本实施例中,终端通过连接切换管理服务器来获取SP的服务器信息,切换管理服务器的地址信息可以预置在终端上,或者终端也可以通过连接当前提供业务的第二运营商SP2的管理服务器,获得这个第三方的切换管理服务器的地址信息。 [0023] In this embodiment, the terminal server information acquired by the connection SP handover management server, the address switching information management server may be preset in the terminal, or the terminal services may be provided by connecting the second current operator SP2, management server, obtain the address information of the third party switch management server.

[0024] 需要说明的是,终端既可以在用户选择需要切换到第一运营商SPl后,再连接切换管理服务器实时获取SP的服务器信息,也可以定时或根据需要连接切换管理服务器更新所保存的SP的服务器信息,以便需要切换时使用,例如: [0024] Incidentally, the terminal can choose the operator needs to switch to a first SPl user, then the management server connected to the switching server information acquired in real time the SP, or may be connected to the switching timing of the management server updates the stored as required SP server information, when the need to switch to use, for example:

[0025] (I)终端可以定时连接到切换管理服务器获取每个SP的服务器信息;或者终端在每次开机的时候连接到切换管理服务器获取每个SP的服务器信息。 [0025] (I) connected to the switching timing of the terminal may acquire the server information management server to each SP; or boot time each terminal connected to the switching server information management server acquires each SP.

[0026] (2)终端可以在用户选择需要切换到SPl之后,连接到切换管理服务器获取每个SP的服务器信息,当然,由于终端已确定需要切换到SP1,它也可以从切换管理服务器只获取SPl的服务器信息。 [0026] (2) after the user selects the terminal may need to switch to SPl, connected to the switching server information management server acquires each SP, of course, since the terminal has determined need to switch to SP1, which can be obtained from the handover management server only SPl server information.

[0027] 切换管理服务器提供的SP的服务器信息具体可以是每个SP的管理服务器的地址信息。 [0027] SP switching server information management server may be provided by the particular address information of each SP management server. 所述管理服务器是具有能够向终端提供DRM信息的功能的服务器或服务器的集合。 The management server is capable of providing a set of DRM having terminal function information to the server or servers. 例如,管理服务器可以包括为终端提供管理配置功能的自动配置服务器(ACS,Auto-configuration Server)。 For example, the management server may include a provisioning function to provide management terminal auto-configuration server (ACS, Auto-configuration Server).

[0028] SP通常都提供自动配置服务器,自动配置服务器负责对终端进行自动管理,能够实现对终端里各种参数读取和设置修改。 [0028] SP typically provide automatic configuration server, the autoconfiguration server is responsible for managing the automatic terminal, the terminal can be realized in various modifications reading and setting parameters. 因此终端可以通过某个SP的自动配置服务器来获得该SP的DRM信息。 Thus the terminal DRM information may be obtained by a SP SP auto-configuration server.

[0029] 当然,管理服务器还可以包括为终端提供在线注册功能的注册服务器等,终端可以在线注册完成开户,并从管理服务器获得该SP的DRM信息。 [0029] Of course, the management server may further include a registration server functionality for providing online registration terminal or the like, the terminal can complete online account register, and DRM information obtained from the management server of the SP.

[0030] 管理服务器提供的不同的具体功能可以由不同的服务器实体来实现,例如注册服务器与ACS可以分别为两个独立的服务器实体,管理服务器包括这两个服务器实体,或者这些不同的具体功能也可以在同一个服务器实体上实现。 [0030] The management server provides various specific functions may be implemented by different server entity, such as a registration server and the ACS server may be two separate entities, respectively, the management server includes both a server entity, or these different specific functions It can also be implemented on the same physical server.

[0031] 本实施例中,管理服务器能够提供ACS的功能。 [0031] In this embodiment, the management server ACS function can be provided. 因此,终端从切换管理服务器获取的每个SP的服务器信息可以是每个SP的ACS的地址信息。 Accordingly, the terminal server SP information for each switch obtained from the management server the address information of the ACS may be each SP.

[0032] 102、按照获得的服务器信息向需要切换到的第一运营商的管理服务器发起连接。 [0032] 102, the server information obtained in accordance with the need to switch to the first carrier management server initiates the connection.

[0033] 本实施例中,假定用户已在需要切换到的第一运营商SPl开户,例如,用户通过前往SPl的营业厅或登录SPl的网站等方式完成了开户过程。 [0033] In this embodiment, assume that the user has need to switch to the first operator SPl account, for example, the user has completed the account opening process by going to the operating room SPl or log SPl site and other means. 这种情况下,终端即可按照获得的服务器信息向SPl的管理服务器发起连接。 In this case, the terminal can initiate a connection to the server SPl management server according to the obtained information. 例如,若终端获得的是每个SP的管理服务器的地址信息,则根据用户选择从中选取SPl的管理服务器的地址并与之连接,若终端只获取了SPl的管理服务器的地址,则直接按照该地址与SPl的管理服务器发起连接即可,SPl的管理服务器执行ACS的功能,向终端提供SPl的DRM信息。 For example, if the address information is obtained from the terminal management server for each SP, the user selects the address from which the selected management server according to SPl and connected thereto, if only the terminal acquires address SPl management server directly according to the SPl address and initiates a connection to the management server, SPl ACS management server to perform the function of providing DRM information SPl to the terminal.

[0034] 103、从第一运营商的管理服务器获取第一运营商的数字版权保护信息,该数字版权保护信息用于访问第一运营商的业务。 [0034] 103, to obtain a digital copyright protection information of the first carrier from the first carrier management server, the digital copyright protection information for accessing the first operator's business.

[0035] 终端连接到SPl的管理服务器(提供ACS的功能)后,SPl的管理服务器可以把SPl的DRM信息配置给终端,例如,SPl的管理服务器可以把终端原有的DRM信息更新成SPl的DRM信息,也可以在终端增加SPl的DRM信息。 After [0035] SPl terminal connected to the management server (ACS provides functionality), SPl configuration management server can SPl DRM information to the terminal, e.g., SPl terminal management server can be updated to the original DRM information is SPl DRM information, it can also increase the DRM information SPl in the terminal. 具体获取过程可以通过远程设备管理协议来实现。 Specific acquisition process can be achieved through remote device management protocol.

[0036] 终端获取到SPl的DRM信息后,使用该DRM信息就可以连接到SP1,从而可以访问SPl的业务,例如IPTV业务。 After [0036] SPl terminal acquires DRM information using the DRM information can be connected to the SP1, SPl can be accessed services, such as IPTV service.

[0037] 本实施例中,终端通过切换管理服务器获取SP的服务器信息,所称服务器信息中包括SP的管理服务器的地址信息,用户事先在SPl开户,在需要切换到SPl时连接到SPl的管理服务器获取SPl的DRM信息,即可使用获得的SPl的DRM信息访问SPl的业务,实现到SPl的切换。 [0037] In this embodiment, the terminal server information acquired by switching the SP management server, called Information Server address management information SP included in the management server, the user account in advance SPl, when connected to the need to switch to SPl to SPl DRM server to obtain information SPl, you can use the DRM information obtained SPl access SPl business, to achieve the switch SPl. 本实施例能够让一个终端获得不同SP的DRM信息,使得用户可以用一个终端连接不同的SP,访问不同的SP的IPTV业务,提高了用户的使用体验,也节约了资源。 This embodiment enables a terminal to obtain different DRM information of SP, so that the user can use a different terminal connected to SP, SP access different IPTV service and improve the user experience, but also saves resources.

[0038] 实施例二、请参阅图2,本发明实施例还提供终端切换业务运营商方法的另一实施例,与实施例一相比,本实施例中用户可以实时进行注册,具体步骤包括: [0038] Second Embodiment, see Figure 2, embodiments of the present invention further provides another embodiment of a terminal switching service operator embodiment of the method, as compared with an embodiment, the present embodiment can register a user in real time, specific steps comprising :

[0039] 201、从切换管理服务器获取运营商的服务器信息。 [0039] 201, information acquired from the server operator handover management server.

[0040] 此步骤可参照步骤101执行。 [0040] This step may be performed with reference to step 101. 在本实施例中,SP的管理服务器除了能够提供ACS的功能,还能够提供注册服务器的功能,如前所述,这两个不同的功能既可以实现在不同的服务器实体上,也可以实现在同一个服务器实体上。 In the present embodiment, SP management server ACS addition to providing functionality, also possible to provide the function of the registration server, as described above, two different functions can be either implemented on a different server entity, may also be implemented on the same physical server.

[0041] 202、按照获得的服务器信息向需要切换到的第一运营商的管理服务器发起连接。 [0041] 202, the server information obtained in accordance with the need to switch to the first carrier management server initiates the connection.

[0042] 本实施例中,假定用户尚未在需要切换到的第一运营商SPl开户,因此终端连接到SPl的管理服务器后,需要先执行下述注册过程。 [0042] In this embodiment, it assumes that the user has not been the need to switch to a first operator SPl account, thus the terminal management server connected to SPl, need to execute the registration process.

[0043] 203、完成在第一运营商的注册。 [0043] 203, to complete the registration of the first operator.

[0044] 注册服务可以由SPl的管理服务器中提供注册功能的部分来实现,也可以由SPl的管理服务器中提供注册功能的一个独立服务器实体来实现。 [0044] Registration Service can provide registration function by SPl management server is implemented in part, can also provide a stand-alone server function entity registered by SPl management server to achieve.

[0045] 注册过程包含在SPl的开户过程。 [0045] The registration process is included in the account opening process SPl. 具体注册过程可包括向注册服务器提供可证明身份或用于付费的信息等,例如,用户在连接到SPl的管理服务器时,管理服务器向用户推送注册页面,提示用户输入用户名,手机号码,或用于支付费用的有效银行卡等;SP1的管理服务器认证这些信息后,即可完成用户的开户。 Specific registration process may include providing proof of identity to the registration server or pay for information such as, for example, when a user is connected to the SPl management server, management server push to the user registration page, the user is prompted to enter a user name, phone number, or to pay the cost of effective bank card; SP1 of the management server authentication information to complete the user's account.

[0046] 注册后,为保证SPl的DRM信息的安全传输,本实施例中还可进一步增加终端从SPl的管理服务器获得数字证书的步骤,即: [0046] After registration, the DRM information to ensure the secure transmission of SPl, the present embodiment can further increase the step of obtaining a digital certificate from the terminal management server SPl, namely:

[0047] 204、接收第一运营商的管理服务器发送的数字证书,该数字证书用于第一运营商的数字版权保护信息的安全传输。 [0047] 204, receiving a first digital certificate management server operator sent by the digital certificate for the secure transmission of digital copyright protection information of the first operator.

[0048] 上述步骤204用于进一步提供DRM信息的安全传输,属于可选步骤。 [0048] The step 204 further provides for the secure transfer of DRM information, is an optional step. 该数字证书在终端完成注册后,由SPl的管理服务器中提供注册功能的部分,或由SPl的管理服务器中提供注册功能的一个独立服务器实体发送给终端。 After completion of the digital certificate registered in the terminal registration function provided by the management server SPl section, or a separate server provides a registration function SPl by the management server transmits to the terminal entity. 终端使用这个数字证书,即可从SPl的管理服务器中提供ACS功能的部分,或由SPl的管理服务器中提供ACS功能的一个独立服务器实体获取SPl的DRM信息。 The terminal uses the digital certificate, ACS function can be provided from the management server SPl section, or a separate server ACS function SPl by the management server entity acquires DRM information of SPl.

[0049] 例如,在管理服务器包含注册服务器和ACS两个服务器实体的情况下,终端可以使用从注册服务器获得的数字证书与ACS服务器进行相互认证,在认证通过后,从ACS服务器获取DRM信息。 In the case [0049] For example, in the management server and the ACS server contains two registration server entity, the terminal can be obtained using a digital certificate from the registration server performs mutual authentication with the ACS server, after the authentication, acquiring information from the DRM server ACS.

[0050] 由于该数字证书的使用,可避免将SPl的DRM信息提供给未获授权的终端,保证了DRM信息的安全传输。 [0050] Due to the use of digital certificates, can provide SPl avoid the DRM information to unauthorized terminals to ensure the secure transmission of DRM information.

[0051] 205、从第一运营商的管理服务器获取第一运营商的数字版权保护信息,该数字版权保护信息用于访问所述第一运营商的业务。 [0051] 205, the digital copyright protection information acquiring a first carrier from the first carrier management server, the digital copyright protection information for accessing the first operator's business.

[0052] 本实施例中,终端通过切换管理服务器获取SP的服务器信息,所称服务器信息中包括SP的管理服务器的地址信息,终端连接SPl的管理服务器进行注册,进而获取SPl的DRM信息以访问SPl的业务,实现到SPl的切换。 [0052] In this embodiment, the terminal server information acquired by switching the SP management server includes an address information server called SP information management server, the terminal management server connected SPl registration, and then obtain access to the DRM information SPl SPl operations, the mode switchover SPl. 本实施例进一步使得用户无需事先到每个SP进行开户,即可在需要使用某个SP的业务时,由终端在切换的过程中完成开户和注册,更加方便了用户的使用。 The present embodiment further enables users without prior to account for each SP, SP to the need to use a service, the registration process is completed account and handover by a terminal, more convenient for users to use.

[0053] 前述实施例中,终端分别与切换管理服务器、SPl的管理服务器建立连接,以最终获取SPl的DRM信息。 [0053] In the foregoing embodiment, respectively, and the switching terminal management server, the management server to establish a connection SPl to ultimately acquire the DRM information SPl. 由于DRM信息是用来让SP能够保护自己的IPTV业务,因此为了防止DRM信息被非法传播,可进一步在终端与切换管理服务器、SPl的管理服务器的通信中采用非对称密钥系统,即数字安全证书系统,确保DRM信息的安全传输。 Since the DRM information is used to allow SP to protect their IPTV services, in order to prevent the DRM information is illegally distributed can be further asymmetric key system using the communication terminal and the handover management server, the management server SPl, i.e. digital security certificate system to ensure the secure transmission of DRM information. 下面对该情况进行详细说明。 This case will be explained in detail below.

[0054] 实施例三、请参阅图3,本发明实施例还提供终端切换业务运营商方法的另一实施例,包括: [0054] Embodiment 3 Referring to FIG 3, an embodiment of the present invention further provides another terminal switching service operator embodiment of a method, comprising:

[0055] 301、与切换管理服务器进行认证; [0055] 301 performs authentication and handover management server;

[0056] 当终端需要连接切换管理服务器获取SP的服务器信息时,终端可使用当前提供业务的第二运营商SP2的数字证书认证切换管理服务器,或与切换管理服务器进行相互认证,当通过认证后,再执行后续从切换管理服务器获取SP的服务器信息的步骤。 [0056] When the terminal needs to handover management server connected to the SP acquires the server information, the terminal may use a digital certificate currently providing service to the second operator switch SP2, the authentication management server, and mutual authentication or handover management server, when the certification , then perform the subsequent step SP acquired from the server information management server switching.

[0057] 302、从切换管理服务器获取SP的服务器信息。 [0057] 302, the server acquires handover information from the management server SP.

[0058] 当终端通过切换管理服务器的认证后,终端即可从切换管理服务器获取SP的服务器信息,例如SP的管理服务器的地址等。 [0058] When the terminal is switched by the authentication management server, a terminal server can obtain information from the handover management server SP, SP, for example, address management server.
