Method for transmitting data in a network of distributed stations, and network station
First Claim
1. Method for transmitting data in a home network of distributed stations, in which said distributed stations the functionalities of a device to be controlled are provided on a web server in the form of one or more information pages generated using a description language and are selected by a control point device in order to control a device at the home network which is to be controlled by means of a browser, wherein an expanded device ascertainment service in the control point device is used to find other control point devices in the home network in order to transmit user profile information between two or more control point devices in the network, with one or more additionally implemented user profile services in the control point device being used to send a notification about changed user profile information to the other control point devices in the home network, wherein a list of device types is extended with a device type control point device, and the expanded device ascertainment service is making use of a discovery protocol in which the two or more control point devices are searchable based on an assigned device type or service type, wherein for searching a control point device the expanded device ascertainment service in a requesting control point device is entering a device type control point as a search target in a search request and the expanded device ascertainment service in the search target control point device is answering to this search request in a response message.

Abstract
The invention relates to the technical field of home networks. A home network based on the present UPnP standard (Universal Plug and Play) allows data to be interchanged between network subscriber stations. A UPnP standard may have one or more control point devices. To allow profile information such as user profile or network profile to be interchanged, the invention proposes providing a control point device firstly with an expanded device ascertainment service which can be used to find the other control point devices in the network and also with one or more additionally implemented profile services which allow the other control point devices in the network to be notified about change to profile information on a control point device.
