Description
Technical field
The present invention relates to wireless communication field, particularly a kind of method and device that obtains end message.
Background technology
Aerial download technology (Over the Air, abbreviate OTA as) upload in the air and download technology with portable terminal is closely-related as a kind of, be subjected to extensive concern just day by day, and constantly perfect along with mobile terminal function, the OTA technology also will be applied in the mobile service more and more.
Mobile phone users can be realized data upload and download, functions such as various application programs, download pictures/the tinkle of bells, firmware updating are installed by the OTA technology, OTA has reduced operation maintenance and upgrade cost for functions such as the remote firmware of portable terminal loads, information is uploaded provide technical guarantee.
WiMAX NWG (WiMAX Network Group network working group) is devoted to the research on standard work of OTA technology, the OTA network configuration as shown in Figure 1, the network element that the OTA process relates to mainly comprises:
Terminal MS: be used for the equipment of access network, include but not limited to mobile phone, notebook, PDA, CPE (CPE Customer Premise Equipment customer premise equipment) etc.;
Aaa server (authentication, authentication and accounting server): be mainly used in terminal is carried out authentication;
DM server (device management server, Device Management Sever): be used for the server of management terminal device, existing general management agreement comprises: TR-069 and OMA etc.;
WIB server (WIMAX Initial Bootstrap, initialization start server): be used for providing the information that inserts DM server necessity to terminal to be configured, as: land information such as the user name of DM server and password; And
SPB (Service Provider Backoffice, rear end equipment): the relevant CAMEL-Subscription-Information that is used for providing Network and storage terminal.
Wherein the WIB server can be positioned at identical or different physical network entity with the DM server.
Terminal management is a bigger problem, comprising: the granting of terminal, basic parameter configuration, edition upgrading etc.; Terminal is provided pattern and is mainly comprised:
Custom terminal: dispose some necessary end message and operator's informaitons during appearance, even user profile; According to configuration information what, custom terminal is divided into activated terminals and un-activation terminal again, if the device activation value of statistical indicant (device activate flag) that terminal and DM management server are preserved is TRUE, then this terminal is activated terminals, if the device activation value of statistical indicant that terminal and device management server are preserved is FALSE, then this terminal is the un-activation terminal; Activated terminals does not need initial configuration can finish normal networking flow process, if terminal need be upgraded configuration, network side can further continue configuration to this terminal; The un-activation terminal need be carried out initial configuration and could normally be networked.
Retail terminal: be equivalent to bare machine when dispatching from the factory, some basic certificate informations may be arranged, but also need to carry out normally access network of initial configuration;
Separation between machine and card pattern: be inserted in the terminal in case block, with regard to similar custom terminal.
The basic parameter configuration of terminal mainly comprises customer parameter setting and network parameter and terminal parameter configuration; Customer parameter mainly comprises username and password etc., is mainly used in identifying user, can adopt signatory mode under the line by user and the SPB acquisition of contracting, and also can adopt the signatory mode of the line that carries out after terminal is reached the standard grade; The configuration of network parameter and terminal parameter can realize by aerial download OTA technology.
At present, WiMAX NWG has proposed based on the terminal initial configuration flow of OTA technology and has continued configuration flow, for the un-activation terminal, need carry out the OTA initial configuration and just can normally network, and OTA initial configuration flow process mainly comprises:
In the terminal initial layoutprocedure, terminal need be constructed NAI and be reported aaa server in network authentication messages, if terminal need be carried out initial configuration, be that the device activation value of statistical indicant that terminal is preserved is FALSE, then during terminal constructions NAI, need carry SM (service mode service mode)=1, aaa server confirms that according to the service mode information (SM=1) of terminal to report this terminal need carry out the OTA initial configuration, set up initial Business Stream with terminal and IP is connected, aaa server receives after charging from ASN-GW begins message, can send the end message notification message and give DM server, comprise end message in this notification message, this end message mainly comprises: the key information BEK (starting encryption key bootstrap encryption key) that is used for encrypting bootstrap information, and the timer timer relevant with startup, can also comprise other relevant information of terminal, as MS ID etc.; After the DM server receives, send UDP Push (User Datagram Protocol to terminal, the User Agreement packet pushes) message, this UDP Push message contains the bootstrap information after the encryption of terminal, this bootstrap information is used for terminal and inserts the DM server, mainly comprise and insert user name, password, and the DM server address etc., above-mentioned information is called equipment control account (DM_ACC) information.If terminal has obtained the bootstrap information in this UDP Push message, perhaps terminal is by initiatively initiating the bootstrap information that the WIB discovery procedure has obtained terminal, can preserve DM_ACC information, and to DM server transmission package#1 message, after the DM server is received package#1 message, think that starting terminal is successful, just can carry out follow-up layoutprocedure to terminal, in layoutprocedure, the DM server can be subscribed to terminal information as required, and namely the DM server is to aaa server transmitting apparatus status request message, after aaa server receives, can send the end message notification message to the DM server, comprise end message in this notification message, this end message mainly comprises: key information BEK, and the timer timer relevant with startup, can also comprise other relevant information of terminal, as MS ID etc.After layoutprocedure was finished, terminal namely changed activated terminals into.After configuration finished, terminal exitted network, and later terminal networks with new configuration parameter.
For activated terminals, do not need to carry out above-mentioned initial configuration and just can formally network, as new data or the parameter of needs configuration, maybe need already present data, parameter are replaced, the DM server can directly be configured this terminal, and this configuration is called lasting configuration.
Activated terminals does not need to carry service mode SM=1 and networks, and just can normally network, so aaa server can be after not receiving the beginning message of chargeing at this terminal yet, the end message that active will comprise log-on message such as BEK sends to the DM server.When needs continue configuration to this terminal, the DM server can initiatively be subscribed to terminal information as required, be the DM server to aaa server transmitting apparatus status request message, after aaa server receives, respond this request message, send the SOT state of termination response message to the DM server, comprise end message in this response message, this end message mainly comprises: key information BEK, and the timer timer relevant with startup, can also comprise other relevant information of terminal, as MS ID etc.
Passed through above-mentioned OTA initial configuration and the activated terminals that becomes for the un-activation terminal, just finished the activated terminals of activation when perhaps dispatching from the factory, network side can continue to dispose to it.
The difference of two kinds of activated terminals is:
Passed through the activated terminals of initial configuration, finished start-up course, terminal has been preserved equipment control account (DM_ACC) information, comprises the address information of DM server, lands the user name of DM server and password etc.;
And just finished the activated terminals of activation when dispatching from the factory, if continue configuration for the first time, then terminal does not obtain DM_ACC information, the DM server continues before the configuration to this terminal, need finish the startup flow process to this terminal earlier, the DM server need be subscribed to terminal information to aaa server, needs to comprise log-on messages such as BEK in the ordered end message, to be used for finishing the encryption to bootstrap information.
By foregoing description as can be known, aaa server has to the scene that DM server transmission end message notification message relates to:
1, the un-activation terminal that need carry out the OTA initial configuration is reached the standard grade with SM=1, and aaa server sends to the DM server with the end message notification message, comprises log-on messages such as BEK in this end message notification message; For this scene, it is necessary carrying log-on messages such as BEK, because this terminal need be carried out initial configuration, does not also finish start-up course.
2, as required end message is subscribed to when the DM server, sent the SOT state of termination request message to aaa server, aaa server responds it, if terminal is online, sends carried terminal information in the SOT state of termination response message to this DM server; Wherein response is divided into only response once, and response repeatedly, regardless of one or many, all comprises log-on messages such as BEK in the end message that this SOT state of termination response message carries in the prior art.
But for scene 2,
When the DM server is subscribed to the information of the activated terminals of having finished initial configuration process as required, when if aaa server is received the end message request message of DM server transmission, if terminal is online, aaa server is in the SOT state of termination response message of DM server about status request message, be not need to carry BEK information, do not need log-on messages such as timer timer yet, because for this Terminal Type, when terminal was carried the SM=1 networking before, aaa server sent to the DM server with log-on messages such as BEK information and timer timer; After this process, the DM server no longer needs log-on messages such as BEK;
When the DM server need be subscribed to the un-activation terminal information, when if aaa server is received the SOT state of termination request message of DM server transmission, terminal does not also network, need carry SM=1 could network through initial configuration, in the SOT state of termination response message of aaa server to the transmission of DM server, do not need to carry log-on messages such as BEK information and timer yet, because for this Terminal Type, aaa server can initiatively send to the DM server with log-on messages such as BEK and timer after the SM=1 indication of receiving self terminal.
But if terminal is activated terminals, terminal is when networking, can not report SM=1 to aaa server, aaa server can be initiatively with log-on messages such as BEK notice DM server, before the DM server carries out start-up course to this terminal, the DM server sends the SOT state of termination request message to aaa server and subscribes to end message, aaa server responds this request message, in the SOT state of termination response message of DM server transmission, need carry log-on messages such as BEK, but only be to need to carry in the response message for the first time, response does not repeatedly then need to carry log-on messages such as BEK yet for follow-up response message if desired yet.
At above-mentioned two kinds of scenes, in the prior art, no matter when, if the DM server is subscribed to end message to aaa server, aaa server all comprises and log-on messages such as BEK and timer to the end message that the DM server sends, and do not distinguished, cause the redundancy of end message notification message, wasted system resource.
