An apparatus and method provide for occlusion detection. An example apparatus includes means for: receiving first data comprising a reference viewpoint of a real-world space; receiving second data comprising a position of a target object in the real-world space; transforming, based on the first and second data, at least one of the reference viewpoint and the target object position into a common virtual reference space; generating one or more rays which extend between the reference viewpoint and a respective spatial point associated with the position of the target object in the common virtual reference space; and determining the digital model representing the real-world space and including one or more real-world features, an occlusion status between the reference viewpoint and the target object. The occlusion status is based on an intersection of the one or more real-world features and the one or more generated rays.

A method and apparatus for use in management of a plurality of parameters of customer premises equipment automatically and dynamically selects and/or alters one or more of a plurality of parameters based on credentials. A particular service provider can be authorized to view and/or alter one or more parameters based on credentials associated with the particular service provider. Specific service providers can be restricted to viewing other service provider's parameters while being allowed to change parameters associated with the specific service provider.

Module and associated method for TR-069 object management

A customer device is configured to allow remote installation of an application module and remote configuration from a remote management server. The application module includes a parameter model with model parameters configured for communication automatically between the remote management client residing in the customer device and the remote management server via a remote management protocol. The parameter model further includes at least one description parameter that formally describes a new model parameter forming part of the parameter model. The description parameter triggers creation of the new model parameter at the remote management server.

Application module and remote management server with parameter description model

A remote management system is able to remotely manage service objects () in a bundle (). The remote management system thereto contains a management platform () in a customer device where the bundle () is installed, a remote management server () somewhere in the network, and a management agent () able to expose the service object representation () of the service objects () via a remote management protocol () to the remote management server (). The remote management system in addition is foreseen with a proxy bundle () with a generic interface to populate and export a generic service object representation () of the service objects () towards the management agent ().

Remote management system and method for service objects

A method for automatically configuring a device by means of an automatic configuration means adapted for automatically configuring the device by means of a remote management protocol (RMP), comprising setting up an RMP session between the device and the automatic configuration means is disclosed, wherein when during the RMP session at least one parameter value of the object model of the device is changed, the device communicates the changed parameter value(s) to the automatic configuration means after the initiation and before the termination of the RMP session.

Method for automatically configuring devices in telecommunication networks and devices for use with such methods

An embodiment of the method includes remote configuration of at least one apparatus using a configuration server to configure the apparatus in situ via a network, to which the apparatus and the configuration server are connected. The method includes exchanging information requests and inform messages between the configuration server and the apparatus. The method further includes prioritizing, at the configuration server, the requested information indicated by the at least one of information requests and inform messages. The method also includes sending, from the configuration server, the requested information indicated by the at least one of information requests and inform messages over the network to the apparatus.

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 RPC's executing actions on parameters of an object model and the method comprises the steps of 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. The SavePoint mechanism saves parameter values of the object model prior to any RPC by storing these parameter values at the CPE-side. The SavePoint mechanism may also save a history of the RPC's invoked during the transaction.
