AI Technical Summary

Problems solved by technology

Rebooting doesn't solve the problem because harmful changes have already been implicitly committed during the last TR-069 remote management protocol session, and no fallback mechanism is foreseen in the TR-069 protocol and TR-069 is not related to the watchdog Feedback link between timers

Embodiment Construction

[0048] figure 1 The shown method is used to improve the security of actions performed by Remote Procedure Calls RPCs invoked during a TR-069 Remote Management Protocol session, hereafter referred to only as a TR-069 session, which is a session in a DSL telecommunications system between the client equipment CPE and the auto-configuration server ACS. The TR-069 session consists of several Remote Procedure Calls RPCs that perform actions on parameters of the object model.

[0049] A Remote Procedure Call (RPC) is performed as an atomic action, ie either the RPC succeeds and the action takes full effect, or the RPC fails and the final partial change has not been completed until the point at which the RPC is executed. For example, SetParameterValues, SetParameterAttributes, AddObject, etc. will not affect the object model if an error occurs during the execution of the RPC.

[0050] While RPC atomicity protects changes that occur at the individual RPC level, the present invention ...

Abstract

The invention relates to TR-069 savepoints. A method for improving the security of actions performed by Remote Procedure Calls RPC invoked during a TR-069 Remote Management Protocol session between an Auto- Configuration Server ACS and a Customer Premises Equipment CPE of a DSL telecommunication system. The TR-069 session comprises several RPCs executing actions on parameters of an object model and the method comprises the steps of - starting a TR-069 session wherein RPCs are invoked; - opening a transactional TR-069 session or transaction whereby parameters of the object model handled by RPCs are protected through a SavePoint mechanism! - closing the transaction by the ACS; and either- committing the transaction via a StoreSavePoint RPC invoked by the ACS, or - rolling-back actions of RPCs via a RestoreSavePoint RPC also invoked by the ACS. If the transaction is not committed during a first TR-069 session, the CPE sends an Inform with an event code OpenSavePoint to the ACS during a next TR-069 session and the ACS may reply by including an additional field in the InformResponse to close the transaction.

Description

technical field [0001] The present invention relates to a method for improving the security of actions performed by Remote Procedure Calls RPCs invoked during a TR-069 Remote Management Protocol session between a Client Equipment CPE and an Auto Configuration Server ACS of a DSL telecommunication system, Said TR-069 session includes a plurality of said remote procedure calls that perform actions on object model parameters. Background technique [0002] Such methods are known in the art. The TR-069 Remote Management Protocol includes an object model on which Remote Procedure Calls, RPCs, are invoked. [0003] The remote management protocol is a CPE WAN management protocol CWMP defined by the technical report TR-069 of the DSL Forum for security auto-configuration and other CPE management functions. In other words, TR-069 is a protocol for communication between a CPE and an Auto-Configuration Server ACS that encompasses secure auto-configuration and other CPE management func...
