Embodiment
The embodiment of the invention provides the method for a kind of terminal service switchover operator, and the embodiment of the invention also provides relevant terminal and system.Below be elaborated respectively.
Embodiment one, see also Fig. 1, the method for terminal service switchover operator one embodiment comprises in the embodiment of the invention:
101, obtain the server info of operator from the handover management server.
The user uses the terminal to obtain when service from SP, may need to change SP.For example; When the user find normally to connect current when professional SP is provided (for example; The Operator Specific Service information or the DRM information at terminal are damaged, and for simplicity, this paper provides professional SP to be called second SP2 of operator with current); Perhaps working as the user hopes to switch to another operator (for simplicity from SP2; This paper hopes that with the user SP that switches to is called first SP1 of operator) so that visit different IPTV when professional, this user understands operating terminal and selects operator, carries out switching by the terminal according to user's selection.For example, when the terminal was STB, the user can select operator through the remote controller of STB or the switching push button on the STB; When the terminal is mobile phone, can select operator through the keyboard of mobile phone self or the dummy keyboard on the touch screen.
In the present embodiment; The terminal is through connecting the server info that the handover management server obtains SP; The address information of handover management server can be preset on the terminal; Perhaps the terminal also can obtain the address information of this third-party handover management server through connecting the current management server that second SP2 of operator of business is provided.
Need to prove; The terminal both can be after the user have selected to switch to first SP1 of operator; Connect the server info that the handover management server obtains SP in real time again; Also can be regularly or connect the server info of the SP that the handover management server update preserved as required, so that use when needing to switch, for example:
(1) terminal can regularly be connected to the server info that the handover management server obtains each SP; Perhaps the terminal is connected to the server info that the handover management server obtains each SP in each start.
(2) terminal can be after the user selects to switch to SP1; Be connected to the server info that the handover management server obtains each SP; Certainly, because the terminal has been confirmed to switch to SP1, it also can only obtain the server info of SP1 from the handover management server.
The server info of the SP that the handover management server provides specifically can be the address information of the management server of each SP.Said management server is to have server or the set of server that the function of DRM information can be provided to the terminal.For example, management server can be included as the terminal provides the Automatic Configuration Server of administration configuration function (ACS, Auto-configuration Server).
SP provides Automatic Configuration Server usually, and Automatic Configuration Server is responsible for the terminal is managed automatically, can realize the various parameters of lane terminal are read and be provided with modification.Therefore the terminal can obtain the DRM information of this SP through the Automatic Configuration Server of certain SP.
Certainly, management server can also be included as the registrar etc. that the terminal provides online registering functional, and the terminal can online registration be accomplished and opened an account, and obtains the DRM information of this SP from management server.
The different concrete function that management server provides can be realized by different server entities; For example registrar and ACS can be respectively two independently server entities; Management server comprises this two server entities, and perhaps these different concrete functions also can be realized on same server entity.
In the present embodiment, management server can provide the function of ACS.Therefore, the server info of each SP of obtaining from the handover management server of terminal can be the address information of the ACS of each SP.
102, initiate to connect to the management server of first operator that needs switch to according to the server info that obtains.
In the present embodiment, suppose that the user opens an account at first SP1 of operator that needs switch to, for example, the user has accomplished the process of opening an account through the business hall of going to SP1 or the modes such as website of logining SP1.In this case, the terminal can initiate to connect to the management server of SP1 according to the server info that obtains.For example; If what the terminal obtained is the address information of the management server of each SP; Then according to the user select therefrom to choose SP1 management server the address and be attached thereto, if the address that the terminal has only obtained the management server of SP1, then directly be connected with the management server initiation of SP1 and get final product according to this address; The management server of SP1 is carried out the function of ACS, and the DRM information of SP1 is provided to the terminal.
103, obtain the digital copyright protecting information of first operator from the management server of first operator, this digital copyright protecting information is used to visit the business of first operator.
After the terminal is connected to the management server (function of ACS is provided) of SP1; The management server of SP1 can be given the terminal DRM information configuration of SP1; For example, the management server of SP1 can become the original DRM information updating in terminal the DRM information of SP1, also can increase the DRM information of SP1 at the terminal.Concrete acquisition process can be realized through the remote device management agreement.
After the terminal gets access to the DRM information of SP1, use this DRM information just can be connected to SP1, thereby can visit the business of SP1, for example IPTV is professional.
In the present embodiment; The terminal obtains the server info of SP through the handover management server; Comprise the address information of the management server of SP in the alleged server info, the user opens an account at SP1 in advance, and the management server that when needs switch to SP1, is connected to SP1 obtains the DRM information of SP1; Can use the business of DRM message reference SP1 of the SP1 of acquisition, be implemented to the switching of SP1.Present embodiment can let a terminal obtain the DRM information of different SP, makes the user can use a terminal to connect different SP, and the IPTV that visits different SP is professional, has improved user's experience, has also practiced thrift resource.
Embodiment two, see also Fig. 2, the embodiment of the invention also provides another embodiment of terminal service switchover operator method, compares with embodiment one, and the user can register in real time in the present embodiment, and concrete steps comprise:
201, obtain the server info of operator from the handover management server.
This step can be carried out with reference to step 101.In the present embodiment; The management server of SP can also provide the function of registrar, as previously mentioned except the function of ACS can be provided; These two different functions both can be implemented on the different server entities, also can be implemented on the same server entity.
202, initiate to connect to the management server of first operator that needs switch to according to the server info that obtains.
In the present embodiment, suppose that first SP1 of operator that the user does not switch at needs as yet opens an account, so after the terminal is connected to the management server of SP1, need to carry out earlier following registration process.
203, completion is in the registration of first operator.
Registration service can provide the part of registering functional to realize in the management server by SP1, also can provide a separate server entity of registering functional to realize in the management server by SP1.
