Abstract

A CPE offline notice method and the corresponding device in the field of communication technologies are provided. The CPE sends an offline message by the remote procedure with offline informing function before getting offline. The device receiving the offline message gets to know that the CPE has got offline. The corresponding device includes an offline notice module to send an offline message by the remote procedure with offline informing function before the CPE gets offline. Since the CPE initiatively sends the offline notice to the ACS, ACS can achieve the CPE's state of online or offline. On the condition that the ACS needs to initiatively connect to the CPE, ACS would not try to connect to the certain CPE, and the resources of ACS can be saved.

Description

Method and device for offline notification of user premises equipment

[1] Technical field

[2] The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for offline notification of a user premises equipment.

[3] Background of the invention

[4] DSL (Digital Subscriber

Loop, digital subscriber line) is a broadband access technology that has been widely used in thousands of households. Its typical networking mode is shown in Figure 1. The wide application of DSL technology expands the application range of broadband technology, such as VoIP (Voice over IP, IP voice), IPTV (IP)

Television, IP TV), etc. A combination of these applications or applications forms a wide variety of IP-based device types. These IP application terminals entering the home are currently called CPE (Customer Premises Equipment), and are used by ACS (Auto-configuration Server,

Automatic configuration server) Responsible for automatic configuration of CPE, so that CPE can work normally without user setting.

[5] At present, the CPE interacts with the ACS, and the specification for automatic configuration and device management stipulates that after the CPE is powered on or restarted, it must pass the Inform method to "1".

The BOOT "event type" issues an announcement to the ACS, whereby the ACS can know if the CPE is already online.

[6] However, the current specification does not provide a mechanism for how ACS learns that CPE changes from online to offline.

. If the CPE has changed from online to offline, the ACS does not know the status change of the CPE, and the CPE is still online. When the ACS needs to actively connect to the CPE, only the connection request is exceeded and the retry is performed. It can be inferred that the CPE may be in the offline or network unreachable state, which increases the burden on the ACS.

[7] Summary of the invention

[8] The embodiment of the invention provides a CPE offline notification method and device, and sends an offline notification before the CPE goes offline.

, enabling related devices to know the status of the CPE.

[9] The embodiment of the present invention is implemented by the following technical solutions: [10] An embodiment of the present invention provides a method for offline notification of a user premises equipment, including:

[11] The user premises equipment issues an offline message using a remote invocation method with an offline notification function before going offline; [12] The device receiving the offline message knows that the user premises equipment is offline.

[13] An embodiment of the present invention provides an offline notification device for a user premises equipment, including:

[14] The offline notification module is used to send offline messages using the remote call method with offline notification before the user premises equipment is offline.

[15] According to the technical solution provided by the foregoing embodiment of the present invention, in the embodiment of the present invention, when the CPE needs to enter the offline state, the CPE sends a CPE offline notification to the ACS before entering the offline state, and the ACS is in the ACS. After receiving the offline notification from the CPE, the CPE will be in the offline state. If the ACS needs to connect to the CPE actively, the ACS will not try to connect to the CPE, which saves the resources of the ACS. There is no need to rely entirely on current super- and retry mechanisms.

[19] Mode for carrying out the invention

[20] The embodiment of the present invention provides a method for offline notification of a user premises equipment. The CPE notifies the ACS that it is offline before the offline, so that the ACS can know the online status of the CPE. The first embodiment of the present invention extends TR-0

The notification mechanism already in the 69 (Technical Report) is to extend the event type in the Inform method and increase the device offline event to achieve. The specific implementation method is as follows.

[21] In the existing Inform, the CPE sends an RPC to the ACS to send a series of event notifications to the ACS. The parameters of the Info rm method are defined as follows:

[25] In this embodiment, the CPE offline event is added by extending the event type supported by the Event parameter in the Inform message. When the CPE needs to enter the offline state, for example, enters the sleep state or the shutdown state, the CPE sends a CPE to the ACS before entering the offline state. After the offline notification is received, the ACS knows that the CPE will go offline after receiving the offline notification from the CPE. If the ACS needs to connect to the CPE actively, the ACS will not try to connect to the CPE, which saves the resources of the ACS.

[30] The second embodiment provided by the present invention is completed by adding a RPC method. After the CPE is ready to go offline, the CPE announces that it is ready to go offline through the RPC method.

The purpose of the RPC method Offline is to notify the ACS that it is ready to go offline. The parameters called by Offline are as follows:

Before the CPE is ready to go offline, it establishes a session with the ACS, and informs the ACS that it is ready to go offline through the Offline message. The parameter OfflineTime indicates the expected offline time of the CPE. At the same time, the existing "1 BOOT" event type is extended, and the reason "CPE resumes from hibernation" is added.

An embodiment of the present invention provides a device for offline notification of a user premises equipment, and a schematic diagram of an embodiment of the device is as shown in FIG. 2, which specifically includes: [35] Parameter expansion module, used to extend CPE related parameters, and increase offline notification mechanism;

[36] The extended CPE related parameters include: expanding the event type of the Inform's Event parameter, adding an offline event, or adding an offline offline RPC method.

[37] The offline notification module is used to actively send offline notifications before the CPE is ready to go offline, using the CPE related parameters extended by the parameter expansion module. The device that receives the offline notification includes a configuration management of the CPE.

SC equipment.

[38] In summary, the present invention sends an offline notification to the ACS through the CPE, and the ACS can obtain the online status of the CPE. When the ACS needs to actively connect to the CPE, the ACS does not attempt to connect to the CPE, which saves the ACS. Resources.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of within the technical scope disclosed by the present invention. Changes or substitutions are intended to be included within the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
