Description

Detector logic and radio identification device and method for enhancing terminal operations

The present invention relates to a short-range communication system, and more particularly, to a wireless radio frequency identification (RFID) module stored in connection with a radio frequency identification (RFID) module for enhancing and indicating the operation of a next terminal in a portable consumer electronic device. The present invention relates to an improvement in an RF-tagging communication system in that it provides a means for directly and internally using frequency recognition information.

Radio frequency identification (RFID) technology is primarily related to the field of local communication technology, and more particularly to local communication technology including electromagnetic and / or electrostatic coupling technology. Electromagnetic and / or electrostatic coupling is performed in the radio frequency (RF) portion of the electromagnetic spectrum, for example using radio frequency identification (RFID) technology, which portion is also a radio frequency, also represented by a radio frequency identification (RFID) tag. A radio frequency transponder reading device, also referred to as a recognition (RFID) transponder and simply a radio frequency identification (RFID) reader.

Originally, radio frequency identification (RFID) technology has been developed and introduced primarily for electronic goods surveillance, goods management purposes and logistics, replacing bar code recognition labels used in conventional goods management purposes and logistics. A typical implementation of a state of the art radio frequency identification (RFID) transponder is shown in relation to FIG. 1. A typical radio frequency identification (RFID) module 10 is a transponder memory 12 with a data storage capacity described herein and a radio frequency (RF) interface 25 connected to each antenna 13 and transponder logic 11. And electrical circuits, usually depicted as examples of transponder logic 11, with a high frequency (HF) interface. Radio frequency identification (RFID) transponders are typically housed in small containers. RFID transponders are typically housed in small containers. Depending on the requirements made for the envisaged application of radio frequency identification (RFID) transponders (i.e. data rate, energy of interrogation, transmission range, etc.), other types may vary from 10 to 100 Hz. It is provided for data / information transmission on other radio frequencies in the range up to (eg, 134 GHz, 13.56 MHz, 860-928 MHz; merely exemplary). Radio frequency identification (RFID) transponders can be divided into two classes. Passive radio frequency identification (RFID) transponders are activated and energized by a radio frequency identification (RFID) reader that generates a question signal, for example a radio frequency (RF) signal of some frequency. Active radio frequency identification (RFID) transponders include their own power supply, such as a battery or accumulator that provides electricity.

During the active state of radio frequency identification (RFID) by the radio frequency identification (RFID) reader, the information contents stored in the transponder memory 21 are detected and received by the radio frequency identification (RFID) reader. Adjusted on the radio frequency (RF) signal transmitted by the antennas 13 of the transponders. Typical radio frequency identification (RFID) transponder technology states conform to radio frequency identification (RFID) standards such as the ISO 14443 Type A standard or the Mifare standard. Depending on the application purpose of the radio frequency identification (RFID) transponder, the information or data stored in the transponder memory may be hard-coded or soft-coded. Hard coding means that information or data stored in the transponder memory 13 is preset or unmodifiable. Soft coding means that information or data stored in the transponder memory 13 can be organized by an external entity. The configuration of the transponder memory may be performed by a radio frequency (RF) signal through the antenna 13, or may be performed through a configuration interface that enables connection with the transponder memory 13.

In particular, in the case of passive radio frequency identification (RFID) transponders (ie, without a local power source), radio frequency identification (RFID) transponders are usually time-varing generated by radio frequency identification (RFID) readers. ) Energized by an electromagnetic radio frequency (RF) signal / wavelength. When a radio frequency (RF) field passes through an antenna coil associated with a radio frequency identification (RFID) transponder, a voltage is generated across the coil. This voltage is used solely to energize radio frequency identification (RFID) transponders and enables back transmission of information from radio frequency identification (RFID) transponders to radio frequency identification (RFID) readers, which are often It is called backscattering.

Interest in various radio frequency (RF) tagging technologies has recently greatly facilitated the development of various radio frequency (RF) tagging applications outside of conventional manufacturing lines and electronic article surveillance applications.

As RF tagging technology is considered to be one of the short-range cross-application delivery technologies in the near future, especially in wireless communication environments, the fundamental characteristics of RF tagging technology are more relevant in connection with applications regarding interaction. There are many issues.

 As soon as a portable device having a radio frequency identification (RFID) transponder logic receives a question signal entering the coverage range of the radio frequency identification (RFID) reader device, the radio frequency identification (RFID) transponder is radio frequency.

A radio frequency identification (RFID) reader device may initiate or provide various services or applications based on data received from a radio frequency identification (RFID) transponder. However, a portable device having a conventional radio frequency identification (RFID) transponder circuit may determine whether the data of the radio frequency identification (RFID) transponder has been read by an external radio frequency identification (RFID) reader device and subject to this determination. It does not have any means to perform the following operations based on that.

In addition, in the case of various transactional applications (such as ticketing services), private and security issues, particularly related to the ticket redemption process, need to be considered. For example, a user may have purchased a mass transit ticket that is valid for a period of time, or a serial one-way or round-trip serial ticket. When such a ticket is given by a radio frequency identification (RFID) transponder providing ticket information, the information is typically private user-related information (eg, social security number, date of birth, customer identification, etc.) and / or other personal information, Security information (eg, ticket identifier, etc.). Such sensitive information should be kept confidential to prevent possible misuse. To ensure that sensitive information is not exposed to any potentially hostile radio frequency reader (RFID) reader device, the mobile terminal can remove security from the radio frequency identification (RFID) transponder to secure it. It would be advantageous to have a radio frequency identification (RFID) transponder circuit capable of determining whether data stored in a radio frequency identification (RFID) transponder has been read to enhance.

It is therefore an object of the present invention to provide an implementation and method based on the fact that a read access to a radio frequency identification (RFID) transponder by a corresponding reader device is detectable and interpretable.

In particular, the present invention is adapted to provide back-end logic such that radio frequency identification (RFID) transponder circuitry provides information regarding the process of reading transponder information stored within a radio frequency identification (RFID) transponder. have.

In particular, the present invention is further adapted to have the detection logic such that the portable device has a radio frequency identification (RFID) transponder and performs the following operations based on the detection decision. The following operations may include, for example, the operation or initiation of the defined preset service (s) and application (s) corresponding to the read radio frequency identification (RFID) transponder data, respectively.

Advantageously, the present invention provides means and methods for enhancing interactions and services by providing internal input within a terminal device to initiate processes associated with certain services and applications. Moreover, the present invention advantageously provides means and methods for reinforcing security and private issues relating to transaction services, particularly in connection with ticketing applications.

The indication may appear as an indication signal that may be directly connected to the portable CE device 100 or may be transmitted to the connected portable CE device 100 via the transponder control logic 210. 2B illustrates a direct connection 310, which allows the detector logic 240 to send a detection signal directly to each of the portable CE device 100 and its processing unit to which it is connected. Optionally, the described data interface (I / F) 215 may be adapted to each of the portable CE device 100 and its central processing unit to which the provision of the detection signal is connected. Correspondingly, the event detected by the detection logic 240 may first be sent to the transponder control logic 210, which then sends an indication to the data interface (IF) 215. Can transmit the detection signal.

For example, whenever the antenna 230 of an RFID transponder is exposed to an appropriate electromagnetic (radio frequency) field, i.e. a query radio frequency signal with predetermined frequencies / frequencys, the RFID transponder is activated. In the case of passive RFID transponders, the RFID transponders are energized by interrogation radio frequency (RF) signals. The activation is detected by the detector logic as a relative detection event sent to the connected portable CE device 100.

2C shows a functional block diagram based on the realization of an RFID module having a transponder function and a reader function. The illustrated RFID module diagrammatically includes an RFID reader logic 211 that represents an RFID reader function and an RFID transponder logic 212 that represents an RFID transponder function. Two functional logic units, namely RFID transponder logic 212, as well as RFID reader logic 211, operate with radio frequency (RF) interface (I / F) 235 (and high frequency interface (HF) respectively). It requires an antenna 230 suitable for a radio frequency (RF) arranged for it. The embodiment illustrated in FIG. 2C aims to use a common antenna 230 and a common radio frequency (RF) interface (I / F) 235 for use by two functional logic units. The radio frequency (RF) interface (I / F) 235 and antenna 230 shown in the present technology in accordance with an embodiment of the present invention is adapted to employ any suitable radio frequency / frequency used in each of the RFID reader and transponder. Adjusted. In more detail, at least the typical operating frequencies mentioned above can be realized with the aid of an embodiment of the invention.

In the case of the RFID reader function, the antenna 230 is adjusted to send one or more query signals and to receive one or more response signals to retrieve information from the RFID transponder.

In the case of an RFID transponder function, antenna 230 receives one or more interrogation signals and transmits one or more response signals that transmit information retrieved from each of the interrogated RFID transponder and its transponder memory.

Antenna 230 provides RF / HF signals generated by radio frequency (RF) interface (I / F) 235 to antenna 230 and accepts RF / HF signals received by antenna 230. A radio frequency (RF) interface (I / F) 235 is connected via one or more signal connections.

Radio frequency (RF) interface (I / F) 235 is responsible for the modulation and demodulation of signals transmitted and received by antenna 230, respectively. Accordingly, radio frequency (RF) interface (I / F) 235 is coupled to RFID reader logic 211 and RFID transponder logic 212, respectively. Specifically, radio frequency (RF) interface (I / F) 235 receives signals from RFID reader logic 211, modulates and transmits them, and transmits demodulated signals to RFID reader logic 211. . Additionally, radio frequency (RF) interface (I / F) 235 also transmits demodulated signals to RFID transponder logic 211, receives, modulates and transmits signals from RFID transponder logic 211. More specifically, the RF interface provides additional signals essential to the operation of the RFID transponder logic 211, which is specifically a power supply signal (voltage signal) and a clock signal. The power supply signal is obtained by coupling of the interrogation electromagnetic field, while the clock signal is obtained by a demodulator included in the radio frequency (RF) interface (I / F) 235. The power supply signal and the clock signal are essential for the operation of the transponder logic 210, respectively, especially when the illustrated RFID module simulates a passive RFID transponder energized by a signal to the RFID reader device. to be.

The RFID module illustrated in FIG. 2C further includes switching logic 213 that is operative to switch between the RFID reader function and the RFID transponder function. The switching logic 213 is located between the RFID reader logic 211, the RFID transponder logic 212 and the radio frequency (RF) interface (I / F) 235, which is generated by the portable CE device 100. It acts as a switching input to receive a switching signal. In detail, the switching logic 213 connects the RFID reader logic 211 to a radio frequency (RF) interface (I / F) 235 or the RFID transponder logic 212 to a radio frequency (RF) interface ( I / F) 235. Correspondingly, depending on the position or switching state of the switching logic 213, an RFID reader function or an RFID transponder function is available.

The RFID module and thus the RFID reader logic 211 are connected by a communication connection 320 which enables an application operated on a portable CE device to enable communication with the RFID module and in particular the RFID reader logic 211. You are provided with the interface that appears. The interface between the RFID module and the portable CE device is established by appropriate hardware and software to enable access to the RFID.

The implemented RFID reader logic 211 takes into account RFID reader functionality as described above. In addition, the RFID reader logic 211 can be adapted to the RFID writer function. This means that an RFID reader with a reader function is adjusted to retrieve information stored in one or more RFID transponders. The reader function is at least the basic function of the RFID reader. An RFID reader with a writer function adds information to an RFID transponder and stores it and / or modifies the information stored in the RFID transponder. The addition and / or modification of the information stored in the RFID transponder depends on the capability of the RFID transponder and / or the authorization of the RFID reader. The register function is an enhanced function of the RFID reader.

The aforementioned RFID transponder function can be employed to establish a communication mode that can be indicated as a show communication mode. In the show communication modes, the RFID reader function is switched off, ie stops operation, while the RFID transponder function is switched. Show communication mode is distinguished from known communication modes in which the RFID transponder function provides the physical advantages of passive RFID transponders that do not require internal power supply. Even when the RFID module is energized by an interrogation signal, which may not be energized by an external / internal power supply, but may be the only server for a limited power supply, the illustrated show communication mode places the need to provide RFID transponder functionality. Consider mainly. This means that the RFID transponder function can be activated by default when the RFID module is powered off, and the RFID module operates with the RFID reader function when the RFID module is powered on. In an embodiment of the present invention, when the portable CE device is powered on (switched on), the portable CE device including the RFID module (internally or externally) energizes the RFID modules. As a result, the RFID reader function is active when the portable CE device is switched on, and the RFID transponder function is active when the portable CE device is switched off. Nevertheless, the switching logic can cause the function to switch between the RFID reader function and the RFID transponder function at any time, upon request or when the RFID module is energized.

The information stored in the RFID transponder module that can be retrieved by the illustrated RFID reader is stored in a suitable storage configuration, such as transponder memory (not shown). The storage configuration can be a read-only storage configuration or a configurable storage configuration. Many storage technologies are applicable in the case of configurable storage configurations, and in particular non-volatile configurable storage technologies are of interest.

The RFID module and thus the RFID transponder logic 212 is a communication connection that enables an application operated on a portable CE device to supply data to each of the RFID transponder logic 212 having an RFID module and in particular a transponder memory. The interface indicated by 300 may be provided. The interface between the RFID module and the portable CE device is established by software and hardware interfaces that enable access to the RFID module.

Similar to FIG. 2B, it is assumed that the RFID module implemented in FIG. 2C is connected to or located within the portable CE device. Usually, an RFID module is an interface such as a serial interface for interfacing information exchanged between the portable CE device 100 and the RFID module such that an application executed by the portable CE device 100 uses the functions provided by the RFID module. Can be provided. An application program interface (API) layer supports communication between the portable CE device 100 and applications running on the RFID module.

As mentioned above in connection with FIGS. 2A and 2B, the detection function generally supports the inspection of the operation of the RFID transponder. With regard to FIG. 2C, the detection function supports the inspection of the operation of the RFID module and in particular of the operation of the RFID module operated in the transponder function (ie transponder mode). This is indicated in the event the detection function is detected with a portable CE device to which the RFID transponder is connected with respect to the operational state of the RFID transponder logic. Similar to the above description, the (detection) event will be recognized as an event in the detection in which the detector logic is provided and configured to signal. More specifically, the detector logic detects, for example, the energization of the transponder logic in response to receipt of the interrogation signal received via the antenna or activation via the interrogation signal, and also as a result of the generation and / or activation of the response signal. It is provided to detect reading-out of the transponder memory for the origination of the response signal. More detection events can be implemented.

In order to detect the energization of the transponder logic in response to receipt of the interrogation signal received via the antenna or activation via the interrogation signal, the detector logic 240 may use a radio frequency (RF) interface (I / F) 235 or It may be connected to the antenna 230, through which the reception of the question signal or the energization of the transponder logic can be detected. Optionally, detector logic 240 may be coupled to transponder logic for the detection of such events and / or for the detection of other events as mentioned above.

The indication may appear as an indication signal that may be directly connected to the portable CE device 100 or may be sent to the connected portable CE device 100 via transponder control logic 210. 2B illustrates a direct connection 310, which allows the detector logic 240 to send a detection signal directly to each of the portable CE device 100 and its processing unit to which it is connected. Optionally, the data interface I / F (not shown) may be adapted to provide a detection signal to each of the connected portable CE device 100 and its central processing unit. Correspondingly, the detected event of the detection logic 240 may first be sent to the transponder logic 212, which then instructs the data interface IF to send a detection signal. Can be.

For example, whenever an antenna 230 of an RFID module is exposed to an appropriate electromagnetic (radio frequency) field, i.e. a query radio frequency signal with predetermined frequencies / frequencys, the RFID transponder is activated. In the case of a passive RFID transponder, the RFID module is energized by a query radio frequency (RF) signal. Activation is detected by detector logic 240 as a relative detection event sent to portable CE device 100 coupled via signal connection 310.

3A and 3B, operation sequences in accordance with an embodiment of the present invention are shown, which relates to the operation of an RFID module or detector logic provided in connection with a transponder and a portable CE device connected to an RFID module and a transponder, respectively. It is about. The operation sequences shown in FIGS. 3A and 3B operate in the embodiment shown in FIGS. 2A-2C.

More specifically, the inventive methodology in accordance with the present invention provides for one or more operations of a portable CE device in which the operation is operable in response to a transmitted detection event sent by the detector logic. In principle, an operation operable in response to a detection event is operable in the current context depending on whether a detection event has been detected. Two distinct ways of determining context information about the current context will be mentioned. The first method is based on contextual information as a result of the information provided by each of the radio frequency identification (RFID) module and the transponder, while the second method is based on the alternative context acquisition means of securing the context to define the current context. It is based on contextual information learned with help.

For example, two basic use cases will be mentioned with the help of which an action sequence is described to facilitate understanding. In the first use case, a variety of RFIDs in which the detector logic implemented with the back-end logic of the RFID transponder provides inputs to a portable CE device to enhance security and privacy essential for many RFID-based ticketing / payment applications, for example. Are employed in connection with the underlying transactional application. In the second use case, detector logic implemented as the back-end logic of the RFID transponder is employed in connection with the RFID based service application. Detector logic supports input into portable CE devices to enhance the utilization and launch of service applications.

With reference to FIG. 3A, a detection event for processing in accordance with an embodiment of the present invention begins at operation 400. This means that the detector logic examines the operation of each of the RFID transponder and RFID module to detect a detector event as defined above.

At operation 410, the RFID transponder / module is calibrated within the coverage of, for example, an RFID reader that emits a question signal. Thus, the detector logic detects a detection event, for example, activation as a response to receipt of the sent out question signal and receipt of the question signal, respectively.

In operation step 420, the RFID transponder or RFID module operates according to its function and sends out a radio frequency (RF) response signal as a result of activation / energy of each of the RFID transponder and RFID module. The response signal transmits the data stored in the transponder memory and reads it out for transmission through the antenna.

In operation of step 430, the portable CE device receives the detection signal originating from the detector logic. The detection signal informs the portable CE device about the sent detector event.

In general, a portable CE device with an RFID module / transponder, i.e., in the case of transponder memory, in which the RFID module / transponder is connected to, included in or inserted into the portable CE device, is stored via data stored in the RFID module / transponder. Can be controlled. However, once data is stored in the transponder memory, the portable CE device is no longer involved in the operation of the RFID module / transponder. Usually, the detection signal originating from the detector logic receiving the RFID module / transponder in accordance with an embodiment of the present invention supports / provides a detection signal that provides information regarding the activity of the RFID module / transponder.

In operation 440, the portable CE device receives a detection signal that provides information regarding the detection event from which the detection signal was sent. Example events are described in detail above; The detection signal here indicates the reception of the interrogation signal by the RFID transponder / module. With knowledge of the detected event indicated by the detection signal, the portable CE device can process and / or react according to certain operations.

As mentioned above, the context that defines the desired action to be processed in response to the received detection signal is determined in accordance with the data stored in the transponder memory and transmitted by the RFID transponder / module. In particular, the type of data stored in the RFID transponder / module and the content of the stored data each support context information. The portable CE device maintains a database, list, etc., for example, which contains a combination between the data type and the corresponding predetermined operation for processing. In general, each of the data types and data stored within the RFID module / transponder is defined in a unique way that the context supports as context information. This includes a combination between a defined context and a corresponding predetermined action in response to a detection signal, such that a database, list, etc., maintained by the portable CE device is processed by the portable CE device.

At operation 450, a detection event processing in accordance with one embodiment of the present invention is terminated.

To illustrate the above described operational sequence with respect to FIG. 3A, an example use case may be presented.

RFID transponders / modules may include ticket or payment related information; That is, they will be used to providing information about electronic tickets or information about certain payment methods (credit cards, cash withdrawal cards, etc.). Such information is sensitive because personal information may be included there. The provision of ticket and payment related information via an RFID transponder is usually under the control of the user of the RFID transponder, while the user must rely on external information regarding the reading of the provided information. According to the external information, the user can determine whether the provided information can be recovered. For the private part, sensitive information will only be provided when absolutely necessary. But the user is not sure whether external information can depend on it. Depending on the invention concept provided and the detection signal provided to the portable CE device, the user may be informed about the reading of the ticket or payment related information, or the provision of the ticket or payment related information is automatically retrieved or the user provides the information. Can be instructed manually to remove.

With respect to the user example briefly illustrated, certain actions may be defined with the data provided therein with respect to the configuration of the transponder. This means that the following retrieval operation is defined in response to an activation instruction of the RFID transponder / module by the RFID reader, at the same time as the configuration RFID transponder / module for the provision of payment or ticket related to the information.

In addition, the portable CE device may initiate an application in response to a detection signal, for example, a wireless data communication connection in which a communication application was initiated and was able to verify that the information provided by the RFID transponder / module was correctly transmitted. To establish. Such wireless data communication connections may include a Bluetooth connection, a wireless local area network (WLAN) connection, an infrared data association (IRDA) connection, and the like.

With reference to FIG. 3B, a detection event to handle in accordance with an embodiment of the present invention begins at step 500. The next operation step 510 to step 530 essentially corresponds to the above-mentioned operation step 410 to step 430. This means that the detector logic examines the operation of the RFID transponder or RFID module to detect a detection event as defined above. In contrast to the operation sequence illustrated with respect to FIG. 3A, embodiments of the present operation sequence relate to the use of other or additional context acquisitions that enable acquisition of contextual information based on which current context can be defined. .

In operation step 510, the RFID transponder / module is arranged within the scope of the RFID reader, for example sending an interrogation signal. Thus, the RFID transponder / module is energized and activated respectively by the interrogation signal.

In operation step 520, the RFID transponder or RFID module operates according to its function and transmits a radio frequency (RF) response signal as a result of activation or energization of the RFID transponder and the RFID module. The response signal transmits the data stored in the transponder memory and reads it out to be transmitted through the antenna.

 In operation step 530, the portable CE device receives the detection signal originating from the detector logic. The detection signal notifies the portable CE device about the sent detection event.

Here, the detection signal transmitted from the detector logic provided with the RFID module / transponder in accordance with an embodiment of the present invention supports / provides a detection signal that informs, for example, about the weakening of the RFID module / transponder. The signal is detected in accordance with operation step 520 following the origination completion of the RFID module / transponder and the next deactivation step.

The portable CE device receives the detection signal in response to the detected event from which the detection signal is sent. In the information about the detected event indicated by the detection signal, the portable CE device may process and / or react according to a predetermined operation.

In operation step 540, the portable terminal determines within the context in which the currently operated context and the detection signal originated.

As briefly mentioned above, the portable terminal may have information regarding data and information currently stored in each of the RFID transponders / modules. For example, the stored information / data was preferentially organized by the portable terminal. Correspondingly, the type of information is known. Thus, one or more of the following operations (referred to in operation step 550 below) may be defined, applied, and planned with respect to a known type of information. As mentioned earlier, this can be canceled immediately, for example after sensitive information stored in the RFID transponder / module is retrieved, the portable CE device can be switched on or off or switched to a defined operating mode, and the user interface Can be configured to provide an action selection for hand initiation by a user of the portable CE device. Optionally, the portable CE device may instruct to initiate or terminate a given application. The number capable of responding to the detection signal can be maintained.

In addition, the context in which the portable terminal may currently operate may be secured in any suitable manner. In particular, the context may be determined or terminated by information provided and supported by external entities. Such information that enables securing of the operating context can be specified as context information based on which the operation of the portable CE device can be applied. While the operation of the portable CE device based thereon is specified as context aware. The securing and processing of contextual information is discussed in detail in connection with FIGS. 4A and 4B.

In operation step 550 the portable CE device is provided with several predetermined operations to be performed following receipt of the detection logic. The portable CE device relates to contextual information based on which selection can operate to select one or more appropriate operations from several predetermined operations. Next, the selected operation (s) is performed. Similar to operation step 440, the portable CE device maintains a list, a database, etc., including, for example, a combination of predetermined contexts and predetermined operations corresponding to the context to be processed by the portable CE device in response to a detection signal. do.

At operation 560, the detection event handled in accordance with an embodiment of the present invention is terminated.

Contextual information, contextual information and contextually relevant information can be recognized as some information based on what the portable CE device can be estimated with respect to the actual context in which it is currently operating. This means that the contextual information is appropriate for performing the above-mentioned selection operation.

It can be seen that two methods of determining the appropriate context are illustrated above. One way to determine the context is to check the context in which the RFID transponder / module is operating. Different ways of determining the context used different means of determining the context from the context according to the contextual information. As a result, the context may be defined by a combination of two example methods of context determination. For example, although the portable CE terminal has determined the current context, such as a movie theater, the selection of the appropriate action can be made based on the RFID transponder / module content. For example, when providing a device address via an RFID transponder / module, setting the Bluetooth module to paging takes precedence over setting the terminal to silent mode, which sets the terminal's pause mode to RFID. Detecting that the module / transponder includes data associated with the movie ticket may be prioritized next.

Acquisition and processing of contextual information will be referred to with respect to FIGS. 4A and 4B, which diagrammatically illustrate an implementation regarding a portable device and an implementation regarding an external resource entity supporting contextual information.

With reference to FIG. 4A, the functional components and units implemented in the portable CE device are described, respectively, including context information acquiring means 600, analyzing means 610, and selecting means 620, wherein the selecting means are operated. Inter-cooperation of causing the portable CE device to perform method context related operations as described in step 550. The context information obtaining means 600 will represent several distinct means for enabling the acquisition of appropriate contextual information. Specifically, the context information acquiring means 602 is a Bluetooth transceiver with a Bluetooth network (N / W) 500, a WLAN transceiver with a WLAN network (N / W), an ultra wideband (UWB). Low power radio frequency (LPRF) interface 602 and radio access network (N / W) (such as transceiver and other transceivers operable with IEEE 802.xx for wireless data communication with corresponding networks) Operate with cellular interface 180 for cellular communication with 520. Optionally, the context information acquiring means 600 may be an RFID transponder or reader 603 as mentioned above, and may be a sensor means such as a GPS module 601. The enumeration of the provided context information acquiring means 600 is not limited, and a portable CE device operable with the present invention may be internally or externally connected to one or more of the illustrated means and / or to acquire appropriate contextual information. It may be connected internally or externally to one or more means applied.

The context information acquiring means 600 is operable to secure contextual information. Specifically, based on which (automated) selection can be operated, the context can be (repeatedly) scanned into (externally provided) information employable as context related information. Appropriate contextually relevant information includes information of several content types relating to other original purposes. The appropriate context related information may include at least location information, location related information, location based information, and dedicated information, respectively.

The scanning operation will be recognized as a passive scanning operation and an active scanning operation respectively. During passive scanning, context information acquiring means is applied, configured or provided to secure context related information, and provision of the information is initiated by an external power source. This can be configured such that the context information acquiring means is ready to receive context related information. During active scanning, the context information acquiring means is applied, configured or provided to actively obtain context related information, for example by active transmission of one or more signals (eg question signals), where context related information is provided. Initiating the provision of is operable.

Location information and location-related information primarily code an indication of the location of a user using a geographic location or location service. The location basic information codes information secured mainly based on the location information. Location information and location related information may be obtained through a cellular network that implements location services and location based services respectively. Optionally, positional information relating to position information may also be obtained from a satellite positioning system (GPS) received by a global positioning system (GPS) module. Dedicated information will be recognized as information related to encoding one or more instructions as certain actions and actions may be associated.

The context information secured by the context information obtaining means 600 is then provided to the analyzing means 600 which is applied to analyze the obtained contextual information. The analysis operation depends on or based on the content of the contextual information previously obtained. As mentioned earlier, the content of contextual information can vary greatly, as may be given a provision to enable an analysis operation.

In other words, dedicated information including one or more instructions for referring to a given action is analyzed to decode a code of the included one or more instructions. The location information, the location related information and the location basic information are analyzed to be combined information by what the operations can identify. Identification of corresponding operations may be obtained by comparing the combining information with data items included in the target operation, or by comparing the combining information with the corresponding additional combining information assigned to the target operations.

Based on the analysis result, the one or more operations are selected from a plurality of predetermined operations maintained by the portable CE device. The selection means 620 is adapted to select one or more operations from a plurality of predetermined operations stored by the portable CE device.

In accordance with one embodiment of the present invention, the contextual information may include the aforementioned low power radio frequency (LPRF) interface 602, cellular interface 180, satellite positioning system (GPS) module 601, RFID transponder / dock. Input from a variety of acquisition means, such as output 603 or the like, the information being dedicated software comprising an analysis means 610 and a selection means 620 connected to, for example, a combined database 621 and an action storage means 622 or Is received by dedicated logic. The association database 621 includes a combination of various contextual information inputs with an operation instruction or reference. This means forming a combination between the current contextual information provided with an instruction or reference and one stored action. The configuration of the join is ensured by employing an appropriate join algorithm. After combining, dedicated software or logic retrieves selected actions associated with the current contextual information for performance.

Analysis means 620 and selection means 630 may each represent program code sections comprising program codes, the program code sections being corresponding when executed by corresponding processing means such as a processor, a controller, or the like. Perform the actions. In addition, the means comprising the analysis means 620 and the selection means 630 mentioned above may represent one or more logic circuits that are adapted to perform the corresponding operations.

Use case

Finally, complex use cases will further explain the operational sequences described in accordance with embodiments of the present invention.

Use cases relating to the purchase and use of movie tickets can be expected. The user has a portable CE device in the form of a communication terminal with an RFID module as implemented above. First, a user connects to a dedicated website for selling an electronic movie ticket, purchases an electronic ticket, and a dedicated service application in the communication terminal configures the memory of the RFID module. The ticket may have been purchased, for example, via a cellular network interface implemented within a communication terminal. In response to the purchase of an electronic movie ticket, the RFID module may include various content, such as the following examples.

The RFID transponder / module is set to "always on", for example providing an address identifier or aka address associated with a low power radio frequency (LPRF) included by the communication terminal when no other indication is set, ie Default setting, terminal identification information;

A 30-day bus ticket set to "hidden" until a suitable context / context (eg bus stop or bus ride) is detected; And

-Newly acquired electronic movie tickets

Late, the user decides to take the bus to arrive at the cinema in time. He walks near the bus stop and uses the RFID module of the communication terminal to scan the RFID transponder provided at the bus stop, which automatically provides access to the bus timetable service. The timetable service is downloaded and the appropriate bus is just coming in. At the same time as scanning the RFID transponder at the bus stop, the context of the communication terminal is changed to "bus stop"; In other words, the information acquired in relation to the RFID transponder at the bus stop supports as contextual information. When a suitable bus arrives, the user brings the communication terminal to the RFID module near the ticket retrieval machine, and the machine reads bus ticket information from the communication terminal (this operation is performed to make it clear that the current context is "bus"). May include preferentially reading the RFID transponder from the retrieval machine, after which the bus ticket information is available in the RFID module.)

The detection logic detects the RFID read operation and determines that the bus ticket information is currently active, so that the communication terminal instructs the RFID module to remove the bus ticket information from the RFID module. Next, the terminal sets back to the above-described readable default setting, that is, the address identifier or the so-called address information. This operation is preferentially performed in accordance with the embodiment described in connection with FIG. 3A.

Inside the bus, the user talks to another user sitting next to him and decides to play a multiplayer tennis game with each other. As the bus is crowded, the easiest way to establish a short-range connection to play a game is to keep the devices close, and an address identifier (or so-called address information) from the RFID module by a corresponding RFID module implemented within another user's communication terminal. Is read by another user.

The detector logic detects an RFID read operation and determines that an address identifier (or so-called address information) is currently active, so that the communication terminal enters a page scanning mode so that the communication terminal's low power radio frequency (LPRF) module (e.g. Bluetooth / WLAN interface), and the communication terminal quickly initiates a low power radio frequency (LPRF) connection. This operation is preferentially performed in accordance with the embodiment described in connection with FIG. 3B.

After getting off the bus, the user enters the cinema, a local service providing a low power radio frequency (LPRF) access point (e.g. a Bluetooth / WLAN access point) connects to the user's communication terminal, and the communication terminal This information is used as contextual information to set it to a "movie theater", making electromagnetic movie ticket information useful. When the user enters the cinema hall, the electronic movie ticket is checked by showing the communication terminal at the entrance where the detection logic provided with the RFID module of the communication terminal signals that the electronic movie ticket information is recovered. The electronic movie ticket information is used by the mobile terminal to initiate the configuration of the communication terminal in stop mode operation or to activate a cinema application that provides additional information related to available movies and the like. This operation is preferentially performed in accordance with the embodiment described in connection with FIG. 3B.

In addition, there is always a possibility that ticket information is erroneously read for some reason. The communication terminal has other near field communication means such as, for example, a low power radio frequency (LPRF) interface that can be used to initiate a near field communication connection with a ticket collection machine to ensure that ticket information provided via the RFID module is read correctly. This problem can be solved at least in part. This may be implemented, for example, by a communication terminal inquiring whether a particular customer number is identified from the ticket collection machine. If not, the communication terminal provides a perceptible alert to the user, re-entering the information into the RFID module of the ticket collection machine. It will be appreciated that other solutions may also be used (eg green light on the ticket collection device if the information is read correctly).

In general, the inventive concept provides a means for the logic of each of the RFID transponder and the RFID module to provide information to each of the connected portable CE devices and their processing units (CPUs) from which the information stored in the RFID transponder / module is read. It is based on "back-coupling detection logic". The processing unit (CPU) may then check the type of information read, or check the actual context in which the information was read, activate, start, and initiate applications, functions, operations associated with the read information.
