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.

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.

Portable electronic device and operation method for establishing a near field communication link

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.

The invention generally relates to the field of markup languages used to describe adaptive mobile multimedia applications and/or presentations being inherently dependent on the dynamic mobile environment they are running in, which means that these mobile multimedia applications and/or presentations need to be adapted to the preferences of mobile users, the capabilities of their mobile computing devices, and their current situation. It allows adaptive mobile stream-based multimedia applications with real-time requirements in a typical wireless scenario (e.g. a radio link with a changing transmission quality and hand-over procedures) to adaptively and responsively react to a time-varying network topology and different radio link characteristics. Thereby, the underlying invention especially includes research and development issues in the field of describing adaptation possibilities (), adaptation constraints () and adaptation events () directed to a personalization and context-aware adaptation of document-based multimedia applications by providing methods for pre-allocating, reserving, monitoring and adapting QoS-related parameters in a dynamic mobile environment using an XML-based multimedia presentation language. In this connection, a document model () consisting of vocabulary, document structure and linking means () between the document model elements is presented which supports the description () of adaptive mobile multimedia applications and/or presentations. Besides, a document object model supporting a simplified transaction-oriented access is proposed.

Adaptive multimedia integration language (AMIL) for adaptive multimedia applications and presentations

The present invention generally relates to the field of mobile multimedia middleware, quality-of-service, shared resource reservation mechanisms, distributed processing systems, handheld computers, computer networking and wireless communication. Particularly, the present invention describes a processing system and pieces of software for one or more communication networks, with middleware comprising an application programming interface () cast over a data model describing quality-of-service contracts and quality-of-service adaptation paths specified by quality-of-service aware mobile multimedia applications () using said programming interface, in order to manage quality-of-service and mobility-aware for managing network connections with other applications. The present invention hereby relates to a corresponding data model as well as the necessary architecture.

High-level interface for QoS-based mobile multimedia applications

A technique for managing the migration of mobile agents to nodes of a communication network is proposed. The trustworthiness of at least one node () of the network is checked (). In case the trustworthiness exceeds a pre-set trust threshold, a trust token for the checked node () is generated () and the trust token is stored () in the network. In advance to a migration of a mobile agent () to a node of the network it is verified () if a valid trust token is existing for the corresponding node (). The migration of the mobile agent () is restricted () to nodes having a valid trust token.

Management of a communication network and the migration of mobile agents

A portal application implemented on a multipurpose computer provides access from a client to a multimedia service. The portal application comprises a plurality of services respectively structured according to a model-view-controller (MVC) architectural pattern and respectively comprising at least one model containing data, a controller and at least one view for the presentation of data of the model. The services are designed to communicate with each other by way of the controller. Therefore, services can be dynamically installed and removed. Due to the presence of a plurality of uses associated with a single controller, the various services are supported to produce different kinds of mark-up languages for each of a plurality of different devices.
