Description

Method, system and device to be loaded for file transfer task status acquisition

technical field

The invention relates to the communication field, in particular to a method, a system and a device to be loaded for obtaining the state of a file transmission task.

Background technique

As a broadband access technology, Digital Subscriber Line (DSL) has been widely used. Various applications based on broadband access technology, such as VoIP, IPTV, etc., require a variety of IP-based terminal equipment, that is, IP application terminals. These IP application terminals are called Customer Premises Equipment (CPE) in the industry. CPE). In order to obtain higher stability, security and availability, CPE often needs to upgrade or update the configuration of the software running on it. Furthermore, software upgrades or configuration updates can also add new functions to the CPE to better serve users.

The operation of upgrading or configuring the software on the CPE is realized by loading files. There are roughly two ways to load the above CPE: one is to send commands/messages to the CPE from the outside of the CPE to let the CPE load; the other is to load the CPE Periodically check relevant information by itself and implement loading.

In the current device management and automatic configuration work framework, CPE acts as the client, that is, the device to be loaded; the automatic configuration server (Auto-configuration Server, ACS) acts as the server, that is, the loading server. CPE and ACS respectively provide some methods for the other party to call. The method of calling the remote device is to send a specific message to the device and wait for the result returned after the device responds to the message. ACS generally uses various remote procedure call (Remote Procedure Call, RPC) methods to realize the modification and setting of CPE parameters.

In the prior art, after the CPE receives the file transfer command from the ACS, the ACS can query the execution status of the file transfer task in the CPE through the GetQueuedTransfers RPC method. The CPE returns the execution status of the file transfer task, including "not yet started", "in progress" and "file transfer completed", respectively indicating that the file transfer has not yet started, the file transfer is being executed, and the file transfer has been completed and has been completed load. However, the "in progress" state cannot distinguish between the three states that the CPE is downloading the file, or has completed the download and is writing to the storage device, or has completed the download and has been written to the storage device but has not yet been loaded. If the CPE is in the process of downloading, the ACS can cancel the download task of the CPE, but if the CPE is in the state of having completed the download and writing to the storage device or has completed writing and waiting to be loaded, the ACS cannot cancel the download task of the CPE at this time.

The inventor found that the existing technology has at least the following defects: when the ACS wishes to cancel a file download task, the file transfer status returned by the CPE obtained from the GetQueuedTransfers query cannot be used to distinguish whether the task is in the process of downloading or not based on the status of "execution". During the process, the downloading has been completed and is being written to the storage device, or the writing has been completed and is waiting to be loaded, so the file transfer task cannot be accurately canceled according to the return status of the CPE.
