Method, ACS (auto-configuration server) and system for obtaining equipment status based on TR069 protocol

Abstract

The invention relates to a method, an ACS (auto-configuration server) and a system for obtaining equipment status based on a TR069 protocol. The method comprises the following steps: sending a connection request to a CPE (customer premises equipment) by an ACS, wherein the connection request carries a wrong user name and password; judging the status of the CPE according to whether authentication error status code synchronously returned by the CPE is received after receiving the connection request. The ACS sends the connection request carrying the wrong user name and password to the CPE and determines that the CPE is in a on-line state according to the status code of authentication error returned by the CPE synchronously, and determines that the CPE is in an off-line state when the ACS waits for a timeout or the ACS receives other status codes. Therefore, compared with the prior art, the equipment status can be obtained with only once HTTP invoking; and the method is simple and efficient.

Description

technical field [0001] The present invention relates to the technical field of network management, in particular to a method for obtaining device status based on the Tr069 protocol (CPE wide area network management protocol), ACS (Auto-Configuration Server, automatic configuration server) and a system. Background technique [0002] With the rapid development of device network management technology and the rapid improvement of network management server performance, the number of devices that need to be managed by the network management server has also increased exponentially. How to quickly and efficiently manage these devices has become a major problem in the network management system. [0003] In the field of network management, the number of devices is huge and there are various types. How to manage these devices has become a big problem. The existing SNMP (Simple Network Management Protocol, Simple Network Management Protocol) due to the insecurity of data transmission and...

Problems solved by technology

[0005] 1. There are many types of devices, and the fixed parameters may not exist on a certain device, causing the device to be clearly online, but the device is considered offline because the fixed parameters cannot be obtained;

[0006] 2. To obtain a certain fixed parameter on the device, it must be configured based on the device type. For example, for type A devices, take the value of A1, and for type B devices, take the value of B1, resulting in a complex network management function structure;

[0007] 3. Obtaining parameters with the Tr069 protocol requires multiple HTTP (HyperText Transfer Protocol) interactions, which is inefficient

[0008] Method 2: At the initial stage of obtaining the state, the network management sends a connection request to the device, and obtains the state of the device by using the HTTP status code returned by the get method of the HTTP protocol, such as figure 2 As shown, since the ACS user name and password are attached to the connection request, the status code 202 can be obtained immediately after the connection request is sent, but then, the CPE (Customer premises equipment, customer premise equipment) will send a pair to the ACS to obtain the device Useless Inform message packet with 6 CONNECTION REQUEST events. Compared with method 1, the efficiency of method 2 is improved, but there is protocol interaction between CPE and ACS, which degrades system performance.
