Problems solved by technology

This can result in a lengthy process and is not suitable for applications requiring high responsiveness, such as those used to switch on heating systems
In addition, the use of end-to-end VPN tunnels prevents operators of PDNs from providing value-added services to users, since operators do not have access to the home LAN and do not know how to identify each LAN-attachable device, such as Perform some operations programmatically

Embodiment Construction

[0035] Preferred embodiments are described below: Residential Gateway for allowing access to one or more LAN-attachable devices from an IMS network through a LAN, CP terminals that can remotely attach to a LAN through an IMS network to control one or more LAN-attachable devices, And a method of controlling one or more LAN-attachable devices from a CP terminal remotely attachable to said LAN through an IMS network.

[0036] For simplicity, the CP terminal capable of registering in the IMS network may be further referred to as SIP-CP.

[0037] figure 2 An embodiment of a method for controlling one or more LAN-attachable devices according to the present invention is shown from a CP terminal remotely attachable to said LAN through an IMS network.

[0038] In this example method, the remote gateway 3 initiates a discovery step S-010 of the LAN-attachable devices 1a-1m over the LAN 4. In particular, the discovery aims at obtaining at the remote gateway 3 a list of identifiers of ...

Abstract

The present invention faces the issues of remotely controlling multiple LAN-attachable devices (1a - 1m) and provides for means and method of controlling the LAN-attachable devices from a CP-terminal (2) through an IMS network (51, 52). Basically, the invention provides for the allocation of unique identifiers to each LAN-attachable device (S-020), the exposure of these identifiers in an appropriate entity under control of a SIP network operator (S-045), fetching these identifiers from the CP-terminal (S050), the submission of control commands from the CP-terminal though the IMS network towards a Remote Gateway (S-055), where the LAN- attachable devices are accessible through a home LAN network, and the submission of corresponding control command from the Remote Gateway towards the LAN-attachable devices (S-060).

Description

technical field [0001] The invention generally relates to the control of household devices connected to a local area network, such as personal video recorders, TVs, washing machines, etc., from so-called control point terminals having data connectivity to said local area network. Background technique [0002] Currently, homes and offices have multiple so-called consumer electronics (hereinafter referred to as CE) devices, such as residential gateways (hereinafter referred to as RGW), TVs, personal video recorders, media centers, etc., which are enabled to connect to a local area network (hereinafter referred to as LAN ). Other non-CE devices (such as washing machines, refrigerators, surveillance devices, etc.) can also be enhanced to be LAN attachable. Thereby a so-called home-LAN may comprise home CE devices and home non-CE devices attachable to said home LAN, and these devices may be accessed and controlled from a control point (hereafter referred to as CP) having access ...
