Description

A method and device for acquiring terminal information

technical field

The invention relates to the field of wireless communication, in particular to a method and device for acquiring terminal information.

Background technique

Over the Air (OTA for short), as an over-the-air upload and download technology closely related to mobile terminals, is increasingly receiving widespread attention, and with the continuous improvement of mobile terminal functions, OTA technology will also become more and more popular. It is widely used in mobile services.

Mobile terminal users can use OTA technology to upload and download data, install various applications, download pictures/ringtones, and upgrade firmware. OTA provides technical support for remote firmware loading and information uploading of mobile terminals, reducing operational costs. Maintenance and upgrade costs.

WiMAX NWG (WiMAX Network Group Network Working Group) is committed to the standard research of OTA technology. The OTA network structure is shown in Figure 1. The network elements involved in the OTA process mainly include:

Terminal MS: equipment used to access the network, including but not limited to mobile phones, notebooks, PDAs, CPE (CPE Customer Premise Equipment), etc.;

AAA server (authentication, authentication and accounting server): mainly used to authenticate the terminal;

DM server (Device Management Server, Device Management Sever): a server used to manage terminal devices, the current common management protocols include: TR-069 and OMA, etc.;

WIB server (WIMAX Initial Bootstrap, initial startup server): used to provide the terminal to be configured with the necessary information to access the DM server, such as: the user name and password for logging in to the DM server; and

SPB (Service Provider Backoffice, back-end equipment): used to provide network services and store relevant contract information of terminals.

The WIB server and the DM server may be located in the same or different physical network entities.

Terminal management is a big topic, including: terminal distribution, basic parameter configuration, version upgrade, etc. The terminal distribution mode mainly includes:

Customized terminal: Configure some necessary terminal information, operator information, and even user information when you leave the field; according to the amount of configuration information, customized terminals are divided into activated terminals and inactive terminals. If the terminal and the device activation flag value saved by the DM management server (device activate flag) is TRUE, the terminal is an activated terminal, if the device activation flag saved by the terminal and the device management server is FALSE, the terminal is an inactive terminal; an activated terminal can complete normal network access without initial configuration In the process, if the terminal needs to update the configuration, the network side can further configure the terminal continuously; inactive terminals need to perform initial configuration before they can access the network normally.

Retail terminal: It is equivalent to a bare machine when it leaves the factory, and may have some basic certificate information, but it needs initial configuration to access the network normally;

Machine-card separation mode: Once the card is inserted into the terminal, it is similar to a custom terminal.

The basic parameter configuration of the terminal mainly includes user parameter settings, network parameters, and terminal parameter configuration; user parameters mainly include user name and password, etc., which are mainly used to identify users, and can be obtained through signing contracts between users and SPB, and offline signing methods can be adopted. It is also possible to use the online signing method after the terminal goes online; the configuration of network parameters and terminal parameters can be realized through OTA technology.

At present, WiMAX NWG has proposed the terminal initial configuration process and continuous configuration process based on OTA technology. For unactivated terminals, OTA initial configuration is required before they can access the network normally. The OTA initial configuration process mainly includes:

During the terminal initial configuration process, the terminal needs to construct the NAI in the network authentication message and report it to the AAA server. If the terminal needs to perform initial configuration, that is, the device activation flag value saved by the terminal is FALSE, the terminal needs to carry the SM ( service mode service mode)=1, the AAA server confirms that the terminal needs to perform OTA initial configuration according to the service mode information (SM=1) reported by the terminal, and establishes the initial service flow and IP connection with the terminal, and the AAA server receives the information from the ASN-GW After the billing start message, a terminal information notification message will be sent to the DM server. The notification message includes terminal information. The terminal information mainly includes: key information BEK (bootstrap encryption key) used to encrypt bootstrap information ), and the timer timer related to startup, and can also include other relevant information of the terminal, such as MS ID, etc.; after receiving it, the DM server sends a UDP Push (User Datagram Protocol, user protocol data packet push) message to the terminal, the UDP The Push message contains the encrypted bootstrap information of the terminal. The bootstrap information is used for the terminal to access the DM server, mainly including the access user name, password, and DM server address. The above information is called device management account (DM_ACC) information. If the terminal obtains the bootstrap information in the UDP Push message, or the terminal obtains the bootstrap information of the terminal by actively initiating the WIB discovery process, it will save the DM_ACC information and send the package#1 message to the DM server, and the DM server receives the package#1 After the message, it is considered that the terminal is successfully started, and the subsequent configuration process can be performed on the terminal. During the configuration process, the DM server can subscribe to the information of the terminal as needed, that is, the DM server sends a device status request message to the AAA server. After the AAA server receives it, A terminal information notification message will be sent to the DM server. The notification message includes terminal information. The terminal information mainly includes: key information BEK, and timer timer related to startup, and can also include other related information of the terminal, such as MS ID wait. After the configuration process is complete, the terminal becomes an active terminal. After the configuration is completed, the terminal exits the network, and then the terminal enters the network with new configuration parameters.

For the activated terminal, it can be formally connected to the network without the above initial configuration. If new data or parameters need to be configured, or existing data and parameters need to be replaced, the DM server can directly configure the terminal. This configuration It's called continuous configuration.

The activated terminal does not need to carry service mode SM=1 to enter the network, and can normally access the network, so the AAA server will not actively send the terminal information including BEK and other activation information to the DM server after receiving the charging start message for the terminal. When continuous configuration of the terminal is required, the DM server can actively subscribe to the information of the terminal as needed, that is, the DM server sends a device status request message to the AAA server, and the AAA server responds to the request message and sends a terminal status response to the DM server message, the response message includes terminal information, the terminal information mainly includes: key information BEK, and timer timer related to startup, and can also include other related information of the terminal, such as MS ID, etc.

The network side can perform continuous configuration on the activated terminal that becomes the activated terminal after the above-mentioned OTA initial configuration from the unactivated terminal, or the activated terminal that has been activated before leaving the factory.

The differences between the two activation terminals are:

After the initial configuration of the activated terminal, the startup process has been completed, and the terminal has saved the device management account (DM_ACC) information, including the address information of the DM server, the user name and password for logging in to the DM server, etc.;

However, if the activation terminal has been activated before leaving the factory, if it is the first continuous configuration, the terminal does not obtain DM_ACC information. Before the DM server performs continuous configuration on the terminal, it needs to complete the startup process of the terminal. The AAA server subscribes to terminal information, and the subscribed terminal information needs to include startup information such as BEK to complete the encryption of bootstrap information.

From the above description, it can be seen that the scenarios involved in sending the terminal information notification message from the AAA server to the DM server include:

1. An unactivated terminal that requires OTA initial configuration goes online with SM=1, and the AAA server sends a terminal information notification message to the DM server. The terminal information notification message includes BEK and other activation information; for this scenario, it carries BEK and other activation information is required because the terminal requires initial configuration and has not yet completed the boot process.

2. When the DM server subscribes to terminal information as needed, it sends a terminal status request message to the AAA server, and the AAA server responds to it. If the terminal is online, it sends a terminal status response message to the DM server that carries terminal information; In order to respond only once, or to respond multiple times, in the prior art, no matter once or multiple times, the terminal information carried in the terminal status response message includes startup information such as BEK.

But for scenario 2,

When the DM server subscribes to the information of the activated terminal that has completed the initial configuration process as needed, if the AAA server receives the terminal information request message sent by the DM server, if the terminal is online, the AAA server responds to the terminal status of the DM server about the status request message In the message, there is no need to carry BEK information, nor does it need to start information such as timer timer, because for this type of terminal, when the terminal carries SM=1 before entering the network, the AAA server has sent BEK information and timer start information such as to the DM server; in the subsequent process, the DM server no longer needs BEK and other startup information;

When the DM server needs to subscribe to the information of the unactivated terminal, if the AAA server receives the terminal status request message sent by the DM server, the terminal has not yet connected to the network, and needs to carry SM=1 to enter the network after initial configuration. In the terminal status response message, there is no need to carry BEK information and timer and other activation information, because for this type of terminal, the AAA server will actively send BEK and timer and other activation information to the DM after receiving the SM=1 instruction from the terminal. server.

However, if the terminal is an active terminal, the terminal will not report SM=1 to the AAA server when the terminal is connected to the network, and the AAA server will not actively notify the DM server of activation information such as BEK. Before the DM server starts the terminal, the DM server sends The AAA server sends a terminal status request message to subscribe to terminal information, and the AAA server responds to the request message. The terminal status response message sent to the DM server needs to carry BEK and other activation information, but it is only required in the first response message. Carry, if it needs to respond multiple times, it is not necessary to carry start information such as BEK for subsequent response messages.

In view of the above two scenarios, in the prior art, no matter under what circumstances, if the DM server subscribes terminal information to the AAA server, the terminal information sent by the AAA server to the DM server includes startup information such as BEK and timer, without distinction , resulting in redundancy of terminal information notification messages, wasting system resources.

Detailed ways

In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and examples.

The embodiment of the present invention discloses a method and device for obtaining terminal information. When the DM server needs to subscribe terminal information to the AAA server, it is activated according to different scenarios whether the terminal status response message sent by the AAA server to the DM server carries BEK or not. Only when it is necessary to continuously configure the terminal that has been activated but does not save DM_Acc information, the terminal status response message sent by the AAA server to the DM server carries startup information such as BEK. In other scenarios, the AAA server The terminal status response message sent to the DM server does not carry startup information such as BEK. By distinguishing scenarios, the redundancy of the terminal status response message sent by the AAA server to the DM server is reduced, saving system resources.

In this embodiment, if the DM server needs to subscribe to the information of the terminal, it detects whether the terminal is an active terminal and the startup state of the terminal; according to the detection result, when subscribing the terminal information to the AAA server, it indicates whether the startup information of the terminal is needed, and the AAA server according to The DM server indicates to send terminal information to the DM server; the method and device disclosed in the embodiments of the present invention make the terminal information sent by the AAA server to the DM server in some scenarios not include terminal activation information, thereby reducing message redundancy , saving resources.

The above method will be described below in conjunction with specific embodiments and flow charts.

Embodiment one

In this embodiment, when the DM server needs to subscribe terminal information to the AAA server, the DM server first detects the terminal status. If the terminal is an activated terminal, and the terminal does not execute the startup process, that is, the DM_Acc information is not saved, the DM server needs to When subscribing terminal information to the AAA server, indicate to the AAA server that information related to activation such as BEK is required; if the terminal is not in the above state, the DM server indicates to the AAA server that information related to activation such as BEK is not required;

The DM server indicates whether it needs startup information such as BEK through a new message that is different from the existing subscription message. For scenarios that require BEK, the name of the message is defined in this embodiment as: a new device status request message NewDeviceStatusRequest, the message carries the terminal identification MSID, and may also carry the valid duration lifetime of the request message, and the AAA server may respond to the request message within the valid time; the corresponding response message is: the new device status response message NewDeviceStatusResponse, and The response message carries startup information such as BEK; for scenarios that do not require startup such as BEK, the existing message is still used in this embodiment, and its name is: device status request message DeviceStatusRequest, which carries the terminal identification MSID. It can also carry the valid duration lifetime of the request message, and the AAA server responds to the request message within the valid time; the corresponding response message is the same as the existing response message, and its name is: Device Status Response Message DeviceStatusResponse, but the response The message does not carry BEK and other activation information;

Referring to Fig. 2, the method for obtaining terminal information disclosed in the embodiment of the present invention includes:

Step 101, if the DM server needs to subscribe the information of the terminal to the AAA server, then the DM server detects whether the terminal is an active terminal, and the startup state of the terminal;

The reason why the DM server needs to subscribe terminal information to the AAA server can be triggered by external conditions or configuration needs, for example: the DM server receives the configuration request sent by the SPB, or other terminal management reasons, for example: during the configuration process, the DM In order to confirm whether the terminal is in the online state, the server sends a terminal status request message to the AAA server. The trigger condition is the prior art and will not be described in detail.

Step 102, if the DM server detects that the terminal is an activated terminal and does not execute the startup process, that is, the DM server detects that the device activation flag value device activate flag saved by the DM server is TRUE, and the terminal is not started, that is, the terminal saved by the DM server If the bootstrapmethod flag of the bootstrapmethod flag is null, the DM server sends a NewDeviceStatusRequest to the AAA server, indicating that the startup information of the terminal is required, such as BEK, and can also include startup information such as the startup timer timer; in addition, it can also carry the valid Time lifetime, so that the AAA server responds within the valid time.

If the DM server detects that the terminal does not meet the above conditions, that is, it does not meet the conditions that the terminal is an active terminal and does not perform the start-up process, the DM server sends a DeviceStatusRequest to the AAA server, indicating that the start-up information of the terminal is not required.

Step 103: If the AAA server receives the NewDeviceStatusRequest message, it replies to the DM server with a NewDeviceStatusResponse message. The response message carries BEK information, and may also include timer and other startup information, and may also carry other terminal information.

If the AAA server receives the DeviceStatusRequest message, it will reply the DeviceStatusResponse message to the DM server. The response message carries other relevant information of the terminal, but does not carry BEK, timer and other startup-related information; that is, the response message carries information other than startup information. terminal information.

If NewDeviceStatusRequest or DeviceStatusRequest carries a valid time lifetime, the AAA server needs to respond within the valid time.

In the above embodiment, in different scenarios, different messages are sent to the AAA server to indicate whether activation information such as BEK is required, so that in some scenarios, the terminal information sent by the AAA server does not include activation information such as BEK, so that Redundancy of messages is reduced and resources are saved.

Embodiment two

The difference between this embodiment and Embodiment 1 is that this embodiment does not change the name of the existing message. When the DM server needs to subscribe to terminal information, the subscription type is carried in the existing terminal status request message sent to the AAA server, indicating Whether startup information such as BEK is required.

Referring to FIG. 3, the method for acquiring terminal information disclosed in the embodiment of the present invention includes:

Step 201, if the DM server needs to subscribe the information of the terminal to the AAA server, the DM server detects whether the terminal is an active terminal and the startup state of the terminal;

This step is similar to step 101 in Embodiment 1 and will not be described in detail.

Step 202, if the DM server detects that the terminal is an activated terminal, and does not execute the activation process, that is, the DM server detects that the device activation flag value device activate flag saved by the DM server is TRUE, and the terminal is not activated, that is, the terminal's value saved by the DM server is TRUE. If the bootstrap method flag is null, the DM server sends a DeviceStatusRequest to the AAA server. The message carries the MS ID of the terminal, and the message also carries request type=need bootstrap, indicating that the bootstrap information of the terminal is needed. For example, the BEK may also include activation information such as the activation timer timer; in addition, it may also carry the valid time lifetime of the AAA reply response message.

If the DM server detects that the terminal does not meet the above conditions, that is, it does not meet the conditions that the terminal is an active terminal and does not perform the bootstrap process, the DM server sends a DeviceStatusRequest message to the AAA server, and the request message does not carry request type=needbootstrap, indicating that No startup information for the terminal is required.

Step 203, if the AAA server receives the DeviceStatusRequest message, carrying request type=need bootstrap in the request message, then replying the DeviceStatusResponse message to the DM server, carrying the BEK information in the response message, and can also include timer and other startup related information, in addition Other terminal information can be carried.

If the AAA server receives the DeviceStatusRequest message, and the message does not carry request type=need bootstrap, it will reply the DeviceStatusResponse message to the DM server. The response message carries other relevant information of the terminal, but does not carry BEK, timer and other startup-related information .

In the above embodiments, in different scenarios, whether the request message sent to the AAA server carries an indication of the need for startup information is used to indicate whether startup information such as BEK is required, so that in some scenarios, the terminal information sent by the AAA server does not include Start information such as BEK is included, thereby reducing message redundancy and saving resources.

Embodiment three

Different from the above embodiment, this embodiment does not change the name of the existing message. When the DM server needs to subscribe to terminal information, the existing terminal status subscription message sent to the AAA server carries the number of reports, indicating whether BEK is required Wait for the startup information.

Referring to FIG. 4, the method for obtaining terminal information disclosed in the embodiment of the present invention includes:

Step 301, if the DM server needs to subscribe the information of the terminal to the AAA server, the DM server detects whether the terminal is an active terminal and the startup state of the terminal;

This step is similar to step 101 in Embodiment 1 and will not be described in detail.

Step 302, if the DM server detects that the terminal is an activated terminal and does not execute the start-up process, that is, the DM server detects that the device activation flag value device activate flag saved by the DM server is TRUE, and the terminal is not started, that is, the terminal's value saved by the DM server is TRUE. If the bootstrapmethod flag is null, the DM server sends a DeviceStatusRequest to the AAA server. The message carries the MS ID of the terminal, and the message also carries report type=one time, indicating that the startup information of the terminal is required. For example, the BEK may also include startup information such as the startup timer timer; in addition, the prior art also indicates that the AAA server is only required to respond to the terminal status response message once.

If the DM server detects that the terminal does not meet the above conditions, that is, it does not meet the conditions that the terminal is an active terminal and does not perform the startup process, the DM server sends a DeviceStatusRequest message to the AAA server, and the value of report type is not limited in the request message, that is, , the value of report type in the DeviceStatusRequest message can be one time or other values, which can be set completely according to the needs; if the value of report type is not one time, it means that the startup information of the terminal is not needed, but the DM server can also consider setting the The report type is set to one time.

303. If the AAA server receives the DeviceStatusRequest message, and the request message carries report type=one time, it replies to the DM server with a DeviceStatusResponse message. The response message carries BEK information, and may also include timer and other startup-related information. In addition, it may also Carry other terminal information.

If the AAA server receives the DeviceStatusRequest message, and the report type value carried in the request message is not one time, it will reply the DeviceStatusResponse message to the DM server. The response message carries other relevant information of the terminal, but does not carry BEK, timer and other activation Related Information.

In the above embodiments, in different scenarios, the number of responses carried in the request message sent to the AAA server indicates whether BEK and other activation information is required, so that in some scenarios, the terminal information sent by the AAA server does not include BEK Wait for startup information, thereby reducing message redundancy and saving resources. Although the startup information of the terminal is not required in some scenarios, the DM server can also consider setting the report type to one time for other reasons, so that the received terminal information includes the startup information, but this kind of scenario is rare, and the report type itself It is also a field in the existing request message, only given a new meaning in this embodiment, no change to the existing message, and the application is simpler.
