An electronic device includes an NFC unit configured to enable near field communication (NFC) with at least one NFC device, a network communication unit configured to communicate with at least one network device, a controller configured to control the NFC unit and the network communication unit to exchange data between the at least one NFC device and the at least one network device.

Electronic device enabling NFC communication

A portable electronic device () with a NFC (near field communication) unit () is switchable between an active mode and a passive mode. A motion sensor unit () records a motion of the portable electronic device (), and outputs a motion signal descriptive for the recorded motion. A processing unit () analysis the motion signal to detect a first predefined motion pattern including an acceleration and a deceleration phase. The NFC unit () is switched into the active mode upon detection of a first predefined motion pattern descriptive for an NFC touch gesture.

A method is provided for generating an electronic coupon comprising generating coupon identification data; generating coupon metadata; and generating the electronic coupon based on the coupon identification data and based on the coupon metadata. Further, a coupon holding device is provided including a coupon receiving unit configured to receive a first electronic coupon; a coupon metadata generation unit configured to generate coupon metadata for the first electronic coupon; and a coupon generation unit configured to generate a second electronic coupon based on the first electronic coupon and the coupon metadata.

Method for generating an electronic coupon, coupon holding device, system for generating an electronic coupon, electronic coupon and computer program product

A method for providing data on the Internet, comprising calculating, using a microprocessor, a value of a predetermined function for said data, wherein the value depends on the data, determining, using said microprocessor, a uniform resource identifier including said value, and storing, at a resource on the Internet, said data, wherein the resource is accessible by using the uniform resource identifier. Further, a method for accessing data on the Internet is provided, comprising retrieving said data from a resource in the Internet by using a uniform resource identifier, determining, using a microprocessor, a part of the uniform resource identifier, the part corresponding to a value of a predetermined function, calculating, using the microprocessor, a further value for said data based on said predetermined function, wherein the value depends on the data, and determining, using the microprocessor, the integrity of said data by comparing said value and said further value.

Method for providing/accessing data on the internet and a respective client, server, and system

Near field communication (NFC) device including a processor and a front end unit (FEU) to communicate with an external reader/writer device. The FEU stores, by first memory, a first number of sets of application parameters, each set including first and second identifiers. The processor stores, by second memory, the application and a second number of the sets. The FEU receives a communication request from the external device, including a certain first identifier. The FEU checks, when the request is received, whether the certain first identifier is stored in the first memory. If yes, a response is sent to the external device, including a respective second identifier, which is in the same set of parameters as the certain first identifier. The FEU sends, each time a request is received, a response to the processor. The processor controls which sets of parameters are stored in the first memory based on the response.

Near field communication device and method for near field communication

In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device requests association with the network and the central controller does not support the profile of the new device. A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller passes the control functionality to the controller-capable device, which becomes the new central controller. Thus it is possible to associate the new device with the net work. The invention allows to integrate devices supporting different profiles into a common network.

Ad-hoc established device network

A first wireless ad hoc network with a certain available amount of bandwidth comprises a plurality of wireless terminals communicating via wireless connections with each other. Each wireless connection requires a certain amount of the available amount of bandwidth. A problem occurs, if a wireless terminal wants to set up a new wireless connection requiring bandwidth or requires more bandwidth for an existing wireless connection and the required amount of bandwidth exceeds the left amount of the available amount of bandwidth of the first wireless ad hoc network. In a state of the art wireless ad hoc network the requested bandwidth cannot be provided and a user application may not be possible. According to the invention, however, the required amount of bandwidth can be provided by splitting the first wireless ad hoc network such that a second wireless ad hoc network is spawned which operates in a different communication channel and thus provides additional bandwidth. The second wireless ad hoc network comprises wireless terminals of the first wireless ad hoc network and/or new wireless terminals.

Bandwidth oriented reconfiguration of wireless ad hoc networks

A method for operating a near field communication system, including a plurality of participating near field communication devices, the method comprising repeatedly changing, for each of the plurality of participating near field communication devices, an operational mode of the respective participating near field communication device between a target operational mode and an initiator operational mode until communication is established between the respective participating near field communication device and another one of the plurality of participating near field communication devices, or until an interruption condition is fulfilled.

Method for operating a near field communication system

A method for operating a near field communication system () of at least a first and a second near field communication device () is proposed. It is a basic aspect of the inventive method to provide a step (S) of supplying action data (AD) from at least one near field communication device () to another one second near field communication device (), wherein said action data (AD) are descriptive for at least one action or application to be performed within a processing section (PR) of the inventive method.

A method of operating a wireless network, including detecting at least one signal of an external radio source, by a network device of the wireless network, during normal operation of the wireless network, in which while detecting, the network device does not send data to another network device of the wireless network, and changing a communication channel or frequency band, if the at least one signal overlaps with a currently used communication channel or frequency band.

Method for operating an RLAN arrangement

In order to optimize data traffic in an ad-hoc established device network, the data traffic is monitored in order to determine which amount of the data traffic to and from a specific device is reflected by the central controller. Reflected data streams should be avoided because they increase the load of the network. If more than a predefined amount of said data traffic is reflected by the central controller, and if the specific device is a controller-capable device, a handover of the control functionality is performed in order to establish said specific terminal device as the new central controller. Thus, reflected data streams are reduced.

A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller () passes the control functionality to the controller-capable device (), which becomes the new central controller ().
