 [51] Embodiment 1

 [52] The first embodiment provides a method for managing a terminal device, which is used by an ACS of a plurality of operators to manage a terminal device. In this embodiment, the first server is an access server, and the second server is a service server. For example, the service server actively requests the management of the terminal device. The signaling flow chart is shown in Figure 2, including:

 [53] Step 101: The access server receives a trigger message that the service server manages the terminal device.

 [54] It can be understood that the process of the present invention initiates a redirection process by triggering the configuration of the access device to the terminal device by the service server. After the user first opens the service, the access server establishes a connection with the terminal device and performs redirection. In the subsequent normal operation, if the service server reconfigures the relevant parameters in the terminal device, the active triggering is required, so that the technical solution of the embodiment of the present invention is used. Specifically, the information may be initiated by, for example, negotiation at the OSS level.

 [55] Step 102: The access server sends a redirect message including a service server address to the terminal device according to the trigger message.

[56] The address of the service server here may be a uniform resource locator (URL) and the like, which can identify the location of the service server, can be obtained by receiving the trigger message, or can be read by reading the access server. Information obtained by means of information.

 [57] Step 103: The terminal device receives the redirect message including the service server address, establishes a connection with the service server according to the address of the service server in the redirect message, and accepts the service server. management.

 [58] It can be understood that the terminal device disconnects from the access server while establishing the connection with the service server. If the terminal device needs to accept the management of the second service server, the terminal device can re-establish the connection with the access server. Redirected to the second service server; can also be redirected to the second service server by the currently connected business server.

 [59] Here, the service server configures the terminal device mainly by configuring a parameter of the terminal device by using a configuration command, and the parameters include: configuring a network address translation (NAT) mapping, and setting a quality of service (QoS). Specific parameters such as related parameters or queues, cross-validation, conflict parameters, etc.

 [60] It can be seen that, in this embodiment, the terminal device can accept the management of the ACS of multiple operators by using the following: Using the redirection mechanism, the access server redirects the terminal device to the service server, so that the terminal The device can directly accept the management of the service server. Compared with the prior art, the management content of the terminal device of the service server is not limited by the information related to the access server, and the time spent in the management process is reduced.

[63] Step 201: The service server sends a trigger message for managing the terminal device, and triggers the access server to establish a connection with the terminal device and perform redirection;

[64] Step 202: The access server establishes a connection with the terminal device, and sends a redirect message containing the address of the service server to the terminal device.

[65] Step 203: The terminal device establishes a connection with the service server according to the address of the service server in the redirect message, and accepts management of the service server.

[66] Step 204: The access server performs an inspection on the management content that the terminal device accepts the management of the service server. Certificate.

 [67] The verification here may be to verify whether the content managed by the service server for the terminal device exceeds the range allowed by the access server, or whether the content of the setting affects the normal operation of other services on the terminal device. If the verification verification is out of scope or affects other services, the access server may modify the content of the configuration to the allowed range or not affect the scope of other business operations according to the protocol modified with the service server.

 [68] Using the management method of the terminal device in this embodiment, when the service server needs to manage the terminal device, the access server may be actively triggered to establish a session with the terminal device, and the terminal device is redirected to the service during the session. The server realizes the direct management operation of the service server to the terminal device. Compared with the first embodiment, the second embodiment adds a step 204, so that the management of the terminal device by the service server does not affect the operation of other services on the terminal device.

If the service server is interested in the configuration and parameters of the terminal device, the service server may negotiate with the access server through the OSS layer, and the access server redirects the terminal device to the service after the parameter related to the management information changes in the terminal device. The server, and accepts management of the business server.

 [81] Step 402: The access server establishes a connection with the terminal device, and sets the terminal device according to the received management information;

 [82] The access server may set the attribute in the terminal device data model according to the management information, and request the change information to be reported to the access server after the information related to the management information changes in the terminal device.

 [83] Step 403: When the parameter value of the terminal device that needs to be reported is modified or other event message, the request information is sent to the access server; the request information may include an event message that is of interest to the service server, and may further include access The event message that the server is interested in.

[84] It can be understood that sending the request message to the access server does not depend on the occurrence of step 401 and step 402, and the terminal device can actively send the request message to the access server, and the access server determines to accept the corresponding according to the change information in the request message. The management of the service server, as described in the third embodiment, is not mentioned here. [85] Step 404: The access server checks, according to the received request message, the management information of the received service server, that the terminal device needs to accept the management of the service server, and if yes, step 405 is performed.

 [86] The access server checks the change information of the terminal device according to the management information of the received service server (the management information received in step 402), and can compare the terminal device by comparing the change information of the terminal device. Whether the change information belongs to the scope of the management information, and determines whether the terminal device accepts the management of the service server.

 [87] It can be understood that this step does not depend on step 401 and step 402. The access server can negotiate with the service server requested in the request message to check whether the terminal device has the right to accept the management of the service server.

[88] Step 405: The access server sends a redirect message to the terminal, where the redirect message includes an address of the service server.

 [89] Step 406: The terminal device is redirected to the service server according to the received redirect message and accepts management of the service server.

 [90] The terminal device of the solution can actively report the change information to request the management of the service server, so that the terminal device uses the service and is no longer passive, and the user can select the service according to his or her preference.
