Description

METHODOLOGY, MODULE, TERMINAL AND SYSTEM THAT MAKE POSSIBLE THE PROGRAMMED OPERATION OF AN IDENTIFICATION SUBSYSTEM BY RADIO FREQUENCY AND A COMMUNICATION SUBSYSTEM WIRELESS DESCRIPTION OF THE INVENTION The present invention relates to short-range communication systems. Particularly, the present invention refers to the almost simultaneous operation of a radiofrequency identification reading interface.

(RFID) in cellular communication terminals. More particularly, the present invention relates to an operation aligned in time and frequency of a radio frequency identification (RFID) reader interface with respect to cellular communication. Radio frequency identification (RFID) technology refers basically to the field of local communication technology and more particularly to local communication technology that includes electromagnetic and / or electrostatic coupling technology. The electromagnetic and / or electrostatic coupling is implemented in the radiofrequency (RF) portion of the electromagnetic spectrum using for example radio frequency identification (RFID) technology, which mainly includes radio frequency identification (RFID) transponders REF. : 189848 also known as radio frequency identification (RFID) tags and radio frequency identification (RFID) reader interfaces for radio frequency transponders also indicated for simplicity as radio frequency identification (RFID) readers. In the near future, an increasingly higher amount of different radio technologies will be integrated into mobile terminals. An expanding range of different applications leads to the need and requirement to provide radio access methodologies with different data speeds, reach, robustness and performance tailored specifically to application environments and use cases, respectively. As a consequence of multi-radio scenarios, problems in the interoperability of mobile terminals activated by multi-radio will become a challenge in development. Radio-frequency identification (RFID) technology is one of the recent arrivals in terminal integration. Radio frequency identification (RFID) communication makes possible new paradigms of use, for example, pair of devices, exchange of security keys or obtaining product information by touching elements provided with radio frequency identification (RFID) tags with a terminal activated by radiofrequency identification communication (RFID). Typically, the scope of operation between the radio frequency identification (RFID) tag and the radio frequency identification (RFID) reader interface in consumer applications is considered to be only a few centimeters. In fact, there have already been product editions in radio frequency identification (RFID) readers integrated into mobile phones. Current implementations are based on Near Field Communications (NFC) technology that operates at 13.56 MHz. The communication in this technology is obtained by inductive coupling and therefore requires quite large coil antennas in both the reader and the label. Moreover, inductive coupling has its limitations when it comes to the range of the radio connection. Typically the maximum range at 13.56 MHz with excitation current and reasonable antenna sizes is approximately 1-2 m. The limited scope of Radio Frequency Identification (RFID) systems at 13.56 MHz has increased the interest in supplying management and logistic logistics application aspects to higher frequencies, particularly UHF (ultra high frequency) and microwave frequencies. At UH frequencies (around 868 MHz in Europe and 915 MHz in the United States according to the frequency assignment) the range that can be achieved in fixed industrial and professional installations is up to ten meters, which allows completely new applications compared to 13.56 MHz. The operation of radio frequency identification (RFID) communication at UHF and microwave frequencies is based on backscattering, that is, the reader (interrogator) generates an excitation signal / interrogation and radio frequency identification (RFID) tag (RFID transponder) alters its antenna impedance according to a specified data-dependent pattern. Currently, the most significant regulatory forum in the UHF band is the EPCglobal that is leading the development of industry-driven standards so that the Electronic Product Code (EPC) supports the use of Radio Frequency Identification (RFID) in commercial networks. rich in information and fast moving current. The short-term objective is to replace barcodes on pallets, and in the long term also on packaging and some individual products. If these objectives become reality, users will obtain product information or pointers for more detailed information to their terminals activated by radio frequency identification (RFID) communication only when they touch an article, which is provided with a radio frequency identification transponder ( RFID) that complies with EPCglobal. The excitation power generated in a radiofrequency identification (RFID) reader subsystem is reasonably high, of around 100 mW of consumer applications related to multi-watt mobile terminals used in professional fixed applications. The frequency assignments used for the UHF Radio Frequency Identification (RFID) band are the 868 MHz ISM band in Europe and the 915 MHz band in the United States. Obviously, the frequencies used are close to the cellular frequencies used, which are 880 MHz-915 MHz as well as 925 MHz-960 MHz in Europe and 824 MHz-849 MHz as well as 869 MHz-894 MHz in the United States for transmitter and receiver cellular mobile station, respectively. Due to the quite powerful radiofrequency identification (RFID) excitation signal that the radio frequency identification (RFID) reader subsystem emits, there can be severe interference to an operational cellular transceiver located in the same terminal due to an imperfect nature of the Radio frequency identification (RFID) excitation signal in a limited rejection of RF filters. In practice, the radiofrequency identification reading (RFID) antenna and the cellular antenna could be only a couple of centimeters apart from one another and thus the coupling loss would be approximately 10-20 dB. Considering a RF power level of the Radio Frequency Identification Reader (RFID) subsystem of around 20 dBm (corresponding to approximately 100 mW), there could be a 0 dBm signal observed at the antenna port of the cellular transceiver. The cellular antenna and the apparatus with its frequency dependence as well as the RF filter of the end rejects the interference to a certain extent, but the resulting signal level is still high enough to interfere drastically or in some situations even block the desired cell signal . In an extreme case when a maximum integration benefit is sought, the cellular radio and the radio frequency identification (RFID) reader could use the same antenna since the operating frequencies of these systems are typically close to each other and therefore a antenna could serve both systems. An objective of the present invention is to provide a methodology and means to enable the coordinated use of both a radio frequency identification (RFID) subsystem and a wireless communication subsystem. In particular, the considered coexistence applies to a cellular communication subsystem and a radio frequency identification (RFID) subsystem integrated in the same terminal device. The radio frequency identification (RFID) subsystem causes interference by means of a high noise floor to any wireless communication subsystem operating in that mobile terminal. The object of the present invention is solved by the features of the accompanying independent claims.

Throughout the following description, the same and / or same components will be mentioned by the same reference numbers. Next, the concept of the present invention will be described with reference to the cellular communication subsystem, which in particular supports GSM, GSM / GPRS, GSM / EDGE, cdma2000, and / or UMTS cellular communication. Furthermore, radio frequency identification (RFID) communication will be described with reference to ultra high frequency (UHF) radio frequency identification (RFID) communication, which in particular supports the EPCglobal standard. It should be noted that the specifications mentioned above of the cellular communication subsystem as well as the radio frequency identification (RFID) reader subsystem are given for illustration purposes. It should be understood that the invention is not limited thereto. Originally, radio frequency identification (RFID) technology has been developed and introduced for electronic article surveillance, article management and logistics purposes mainly to replace identification labels with bar codes, which are used for management purposes. of articles and logistics to date. A typical implementation of a radio frequency identification transponder (RFID) of the current art is shown with respect to Figure 1. A typical radio frequency identification (RFID) module 10 conventionally includes an electronic circuit, exemplified as a logical transponder 12, with data storage capacity, illustrated herein as transponder memory 13, and a radio frequency (RF) interface 11, which couples an antenna 14 to the transponder logic 12. Radio frequency identification (RFID) transponders are typically accommodated in small containers, mounted particularly in the article that will be labeled by means of adhesive. Depending on the requirements made in the contemplated applications of radio frequency identification (RFID) transponders (ie, the data transmission speed, interrogation power, transmission range, etc.) different types are provided for the transmission of data / information at different radio frequencies within a range of several 10-100 kHz to some GHz (eg, 134 kHz, 13.56 MHz, 860 MHz-928 MHz, etc.; only for illustration). Two major classes of radio frequency identification (RFID) transponders can be distinguished. Passive radio-frequency identification (RFID) transponders are activated and energized by radio frequency identification (RFID) readers, which generate an excitation or interrogation signal, for example a radio frequency (RF) signal at a predefined frequency. Passive radio-frequency identification (RFID) transponders comprise their own power supplies (not shown) such as batteries or accumulators for energization. After the activation of a radio frequency identification transponder (RFID) by means of a radio frequency identification (RFID) reader module 20, the information contents stored in the memory of the transponder 13 are modulated in a radio frequency (RF) signal. (that is, the interrogation RF signal), which is emitted by antenna 14 of the transponder radio frequency identification module (RFID) 10 to be detected and received by the radio frequency identification (RFID) reader module 20. More particularly, in the case of a passive radio frequency identification (RFID) transponder (i.e., that has no local power source) ), the radio frequency identification transponder (RFID) is conventionally energized by a time-varying electromagnetic radio frequency (RF) signal / wave generated by the interrogating radio frequency identification (RFID) reader. When the radio frequency (RF) field passes through the antenna associated with the radio frequency identification (RFID) transponder 10, a voltage is generated across the antenna. The voltage is used to energize the radio frequency identification (RFID) transponder 10, and enable the retrotransmission of information from the radio frequency identification (RFID) transponder to the radio frequency identification (RFID) reader, which is sometimes referred to as backscatter. The typical current RFID transponders correspond to radio frequency identification (RFID) standards such as the ISO 14443 TYPE a, the Mifare STANDARD, the Near Field Communication (NFC) standard and / or the EPCglobal standard. In accordance with the purpose of application of a radio frequency identification (RFID) transponder, the information or data stored in the memory of the transponder 13 can be either hard coded or soft coded. Hard coded means that the information or data stored in the memory of the transponder 13 are predetermined and non-modifiable. Soft encoded means that the information or data stored in the memory of the transponder 13 are configurable by an external entity. The configuration of the memory of the transponder 13 can be carried out by a radio frequency (RF) signal received by means of the antenna 14 or it can be carried out by means of a configuration interface (not shown), which allows access to the transponder memory 13. A radio frequency identification (RFID) reader module 20 typically comprises an RF interface 21, a logic reader 22 and a data interface 23. The data interface 23 is conventionally connected to a host system such as a terminal portable, which, among others, on the one hand exercises control over the operation of the radio frequency identification (RFID) reader 20 by means of instructions transmitted from the host to the reader logic 22 via the data interface 23 and on the other side receives data provided by the reader logic 22 via the data interface 23. After an instruction to operate, the reader logic 22 initiates the RF interface 21 for the gene The excitation / interrogation signal will be emitted by means of the antenna 24 coupled to the RF interface 21 of the radio frequency identification (RFID) reader module 20. In the event of a radio frequency identification (RFID) transponder such as a radio frequency identification transponder module (RFID) 10 within the coverage area of the excitation / interrogation signal, the radio frequency identification transponder (RFID) is energized and a modulated RF signal (backscatter RF signal) is received therefrom. In particular, the modulated RF signal carries the data stored in the memory of the transponder 13 modulated in the excitation / interrogation RF signal. The modulated RF signal coupled to the antenna 22, demodulated by the RF interface 21 and supplied to the reader logic 22, which is then responsible for obtaining the data from the demodulated signal. Finally, the obtained data of the received modulated RF signal is provided by means of the data interface to the host system. Figure 2 shows a schematic block illustration of components of a portable electronic terminal 10 in an exemplary form of a mobile / cellular telephone terminal. The portable electronic terminal 100 represents exemplary any type of terminal or processing device that can be extended with the present invention. It should be understood that the present invention is neither limited to the portable electronic terminal 100 illustrated nor to any other specific type of terminal or processing device.

As mentioned before, the portable electronic terminal 100 illustrated is exemplary carried out as a portable user terminal activated by cellular communication.

The keyboard and keyboard controller (Ctrl) 130 are provided to enable the user to enter information. The information entered through the keyboard is conventionally supplied by the keyboard controller (C to the processing unit (CPU / MPU) 110, which can be instructed and / or controlled according to the information entered. output (I / O) audio 140 includes at least one speaker to reproduce an audio signal and a microphone to record an audio signal.The processing unit (CPU / MPU) 110 which can control the audio control conversion or audio output signals and the conversion of audio input signals into audio data, where for example the audio data is properly formatted for transmission and storage.The conversion of audio signal from digital audio signals to audio signals audio and vice versa conventionally supports digital to analog and analog to digital circuits, for example, implemented based on a digital signal processor (DSP, not shown). user comprises for example alphanumeric keys and specific telephony keys such as those known for ITU-T keyboards, one or more soft keys having context specific input functionalities, a scroll key (up / down and / or right / left) and / or a combination thereof for moving a cursor on the visual presenter or navigating through the user interface (Ul), a four-way button, an eight-way button, a joystick or a similar controller. The portable electronic terminal 100 according to a specific embodiment illustrated in FIG. 1 includes the cellular communication subsystem 180 coupled to the radio frequency antenna (181) and operable with the subscriber identification module (SIM) 185. The communication subsystem cellular 180 is arranged as a cellular transceiver to receive signals from the cellular antenna that decodes the signals, demodulates them and also reduces them to the baseband frequency. The cellular communication subsystem 180 provides an air interface, which serves in conjunction with the identification module and / or (SIM) 185 for cellular communications with a corresponding base station (BS), base station controller, node B, and the like of a radio access network (RAN) of a public land mobile network (PLMN). The output of the cellular communication subsystem 180 then consists of a data stream that may require further processing by the processing unit (CPU / MPU) 110. The cellular communication subsystem 180 arranged as a cellular transceiver is also adapted to receive data. from the processing unit (CPU / MPU) 110, which will be transmitted via the air interface to the base station (BS) of the radio access network (RAN) (not shown). Therefore, the cellular communication subsystem 180 codes, modulates and upconverts the signals that incorporate data to the radio frequency, which will be used for aerial transmissions. The antenna (delineated) of the portable electronic terminal 100 then transmits the resulting radio frequency signals to the corresponding base station (BS) of the radio access station (RAN) of the public land mobile network (PLMN). The cellular communication subsystem 180 preferably supports a 2nd generation digital cellular network such as GSM (Global Mobile Communications System) which can be activated for GPRS (General Packet Radio Service) and / or EDGE (Increased Data for Evolution). GSM; 2.5 Generation), a 3rd generation digital cellular network such as CDNA (Code Division Multiple Access) including especially UMTS (Universal Mobile Telecommunications System) and cdma2000 System, and / or any similar, related or future standard (ie , 3rd generation, 4th generation) for mobile telephony. The wireless and / or wire data interface (I / F) 160 is exemplarily illustrated and is to be understood as representing one or more data interfaces, which may be provided in addition to or as an alternative to the cellular communication subsystem 180 described above implemented in the portable electronic terminal 100 exemplary. A large number of standards for wireless communication are currently available. For example, portable electronic terminal 100 may include one or more wireless interfaces that operate in accordance with any IEEE 802. xx standard, Wi-Fi standard, WiMAX standard, any Bluetooth standard (1.0, 1.1, 1.2, 2.0 + EDR, LE ), ZigBee networks (for wireless personal area networks (PANs)), Infrared Data Access (IRDA), USB (Universal Serial Bus) and / or any other currently available standard and / or standards for future wireless data communication such as UB (Ultra Wide Band). Moreover, the data interface (I / F) 160 should also be understood as representing one or more data interfaces including in particular wired data interfaces implemented in the exemplary portable electronic terminal 100. This wired interface can support the network of wired base such as LAN Ethernet (Local Area Network), PSTN (Public Switched Telephone Network), DSL (Digital Subscriber Line) and / or other available as well as future standards. The data interface (I / F) 160 can also represent any data interface that includes any private serial / parallel interface such as a universal serial bus (USB) interface, a Firewire interface (in accordance with any IEEE 1394 standard / 1394a / 1394b, etc.), a memory bus interface including a bus that adapts to ATAPI (Packet Interface for Advanced Technology Fixing), an MMC interface (Multimedia Card), a card interface (Secure Card) SD , Flash card interface and the like. The portable electronic terminal 100 according to one embodiment of the present invention comprises a radio frequency identification (RFID) reader subsystem 190 coupled to an RF antenna 194. Reference should be made to FIG. 1 and to the description mentioned above, the which illustrates the basic implementation and operation of a radiofrequency identification reader (RFID) module. The radio frequency identification (RFID) reader subsystem 190 may be included in terminal 100, fixedly connected to terminal 100 or detachably coupled to terminal 100. Moreover, the radio frequency identification (RFID) reader subsystem 190 may be to be provided with a functional cover of the portable electronic terminal 100, which is removably mounted to the portable electronic terminal 100. Preferably the radio frequency identification (RFID) reader subsystem 190 can be integrated into this removable functional cover. According to the inventive concept of the present invention, a programmer 200 is comprised by the terminal 100. The programmer 200 is connected to the terminal 100, the cellular interface 180, and / or the radio frequency identification (RFID) reader subsystem 190 Details about the specific implementation of the radio frequency identification (RFID) reader subsystem 190 and the programmer module 200 are presented below. The components and modules illustrated in Figure 2 can be integrated into the portable electronic terminal 100 as separate and individual modules, or in any combination thereof. Preferably, one or more components and modules of the portable electronic terminal 100 can be integrated with the processing unit (CPU / MPU) by forming a system in a microcircuit (SoC). This system in a microcircuit (SoC) integrates preferably all the components of a computer system in a single microcircuit. A SoC may contain digital, analog and mixed signals, and also commonly radio frequency functions. A typical application is in the area of integrated systems and portable systems, which are restricted especially to size and restrictions of energy consumption. This typical SoC consists of a number of integrated circuits that perform different tasks. These may include one or more components comprising a microprocessor (CPU / MPU), memory (RAM: random access memory, ROM: read-only memory), one or more UARTs (universal asynchronous receiver-transmitter), one or more ports serial / parallel / network, microcircuits DMA controllers (direct memory access), GPU (graphics processing unit), DSP (digital signal processor), etc. Recent improvements in semiconductor technology have allowed VLSI (Very Large Scale Integration) integrated circuits to grow in complexity, making it possible to integrate all the components of a system into a single microcircuit. Typical applications that operate with the portable electronic terminal 100 comprise below the basic applications making possible the data and / or voice communication functionality a contact management application, a calendar application, a multimedia player application, an application of WEB / WAP navigation and / or a message application that supports, for example, Short Message Services (SMS), Multimedia Message Services (MMS) and / or email services. Modern portable electronic terminals are programmable; that is, these terminals implement programming interfaces and execution layers, which make it possible for any user or programmer to create and install applications that operate with the portable electronic terminal 100. A current well-established device-independent programming language is Java, the which is available in a specific version adapted to the functionalities and requirements of mobile devices designated as JAVA Micro Edition (ME). To make possible the execution of application programs created based on JAVA ME, the portable electronic terminal 100 implements a JAVA MIDP (Mobile Information Device Profile), which defines an interface between a JAVA ME application program, also known as a JAVA MIDlet, and the portable electronic terminal 100. The JAVA MIDP (Mobile Information Device Profile) provides an execution environment with a JAVA virtual machine ready to execute the JAVA MIDlets. However, it should be understood that the present invention is not limited to JAVA MID and JAVA MIDlets programming language; other programming languages, especially private programming languages, are applicable with the present invention.

The main concept of the present invention relates to the coexistence of a radio frequency identification (RFID) reader 190 and a cellular radio interface 180 and its concurrent operations. The concept of the present invention will be described with reference to UHF radiofrequency identification (RFID) communication, especially that conforms to the EPCglobal standard for radio frequency identification (RFID) communication. In addition, the concept of the present invention will also be described with reference to a cellular radio interface 180 that especially supports GSM / GSM / EDGE, CDMA and / or cdma2000. However, it should be noted that the present invention is not limited to those specific modalities. Those skilled in the art will appreciate on the basis of the description that the concept of the description is likewise applicable with any other radio frequency identification (RFID) communication standard and wireless communication standard (including especially any other cellular communication standards and standards). of wireless network communication). As mentioned above, specific frequency bands are assigned for UHF radio frequency identification (RFID) communication: band ISM 868 for UHF RFID (Europe): 868-870 MHz (maximum 500 mw) and band 915 for RFID of IHF (USA): 902-928 MHz (maximum 4W). According to the different cellular norms, several frequency bands are assigned for cellular communication. The following table lists a selection of frequency bands used; the table is not exhaustive. For a later reference, the commonly accepted abbreviations for the different frequency bands are designated. Designation RF Band of RF Band of System Upward Link [MHz] Downlink [MHz] GSM 900 (Europe): 890-915 935-960 GSM 1800 (Europe): 1710-1785 1805-1880 GSM 850 (E.U.A.): 824-849 869-894 GSM 1900 (E.U.A.): 1850-1910 1930-1990 Cdma2000 (E.U.A.): 1850-1910 1930-1990 WCDMA 2100 (Europe): 1920-1980 2110-2170 The trained reader will appreciate that the frequency bands used by radio frequency identification (UHF) communication and cellular communications do not overlap. Accordingly, the concurrent cellular communication operation as well as radio frequency identification (UHF) communication (RFID) can be obtained by using RF components of the highest quality, at least theoretically. In practice, these components of the highest quality could be bulky and expensive. Therefore from a cost and size point of view, a solution with the ability to schedule operations of those radios preferably in time domain would be preferable. The excitation / interrogation signal, i.e., the downlink signal of a UHF radio frequency identification (RFID) reader is typically an amplitude or phase modulated carrier. The power of the signal depends on the application, but it could be several watts in industrial applications and possibly a couple of hundred milliwatts in application related to portable terminals.

Typically, the radio frequency identification reader (RFID) emits its excitation signal based on user action (for example, input signal detected after a user presses a button) or application request (for example, generated by an application for example after expiration of a synchronizer). During the exchange of data between the radio frequency identification (RFID) reader and the radio frequency identification (RFID) transponder, the radio frequency identification (RFID) reader continuously outputs the carrier signal to keep the radio frequency identification transponder (RFID) ) energized (see the description mentioned above) The emission of a powerful carrier in an uncoordinated manner during any cellular radio operation would be harmful to cellular radio performance, and therefore this type of situation should be avoided. According to one embodiment of the present invention, the portable terminal 100 has a control entity, which enables the operation of the radio frequency identification (RFID) reader only in coordination with any cellular radio transceiver operation in such a manner that preferably a concurrent or simultaneous operation of both radio frequency identification (RFID) communication and cellular communication can be obtained. In the present, it should be understood that concurrent and / or simultaneous communication operations can be operated at the physical level (lower layer level) multiplexed by time, where time multiplexing is transparent to the user in such a way that they are experienced communication operations substantially concurrent and / or simultaneous. In the first basic case the control entity, the scheduler 200, comprised by the portable terminal 100, checks whether the cellular radio is (completely) turned off before the programmers allow the radio frequency identification (RFID) reader to initiate its interrogation and communication. This first basic approach is quite simple, since raising the cellular operation requires a certain amount of time in a case in which the cellular connection is required just after the radio frequency identification (RFID) communication activity. In a more sophisticated approach, radio frequency identification (RFID) communication activity is scheduled to take place during the inactive periods of cellular operation. The same principle can be applied to different states of the terminal. When the terminal is not connected to the cellular network, the situation of radio frequency identification (RFID) reading is quite direct. Regardless of the cellular system in question, the fixed / standby mode of operation of the terminal listens to location messages, carries out measurements related to energy level between cells and related energy levels of adjacent cells (inter-cells) and availability of other systems, and send random access messages, when required. The activity required in this state is quite low to ensure a long battery life, and therefore there is ample time for radio frequency identification (RFID) communication activity. In the active state, the terminal is either coupled to a voice call or data exchange through a packet connection. This state, and also states that precede and precede the active state (eg, GPRS ready state), require a significant amount of activity, and therefore the time available for the radio frequency identification reading (RFID) operation is pretty limited. For example, there is only (8-2) x 0.577 ms «3.5 ms of time (note that according to the GSM time frame and structure, each frame comprises eight time segments) to achieve radio frequency identification reading operations (RFID) during an active GSM call, since most likely both cellular transmission (a time segment of the eight time segments) and cellular reception (a time segment) would be altered by the identification reading activity by radiofrequency (RFID) in these time segments. Accordingly, according to the present invention the programmer 200 establishes an interface between a radio frequency identification (RFID) subsystem, which is here incorporated as a radio frequency identification (RFID) reader subsystem 190, and the host system, the which is in the present incorporated as portable terminal 100. By means of a programmer algorithm, which is preferably implemented based on the programmer 200 with the help of hardware and / or software implementation, to concurrent multi-radio operation of the way mentioned above becomes possible. Control over the operation of the radio frequency identification (RFID) subsystem is exercised by the host system (ie, hand-held terminal 100) by means of the programmer 200. To make control possible, the radio frequency identification (RFID) subsystem (i.e. radio frequency identification (RFID) reader subsystem 190) can be provided with a radio signal terminal. activation (digital I / O) 196 and monitoring logic. With reference to Figure 2b, a radio frequency identification (RFID) subsystem based on the radio frequency identification (RFID) reader subsystem 190 is illustrated in accordance with one embodiment of the present invention. As mentioned above, the radio frequency identification (RFID) reader subsystem 190 includes the typical components required for a typical radio frequency identification (RFID) reader operation, in particular a data interface (I / F) 191 coupled to the system. host (i.e., portable terminal 100), a logical reader 192 for example implemented based on a microcontroller (μC), and a radio frequency (RF) interface 193 coupled to an RF antenna 194. The monitoring logic 195 agrees with one embodiment of the present invention it is arranged to make possible control capability over the operation of the Radio Frequency Identification Reader (RFID) subsystem 190. The monitoring logic 195 may be integrated in the reader logic or implemented separately. The monitoring logic 195 can be supplied with an activation signal from the host system (portable terminal 100) through an activation terminal 196. The activation signal is provided by the programmer 200 and generated according to the programming algorithm. . The programming algorithm will be described in more detail below. It should be noted that the data interface (I / F) 191 connected to the host system can also be arranged to receive configuration data and instructions from the host system. The data and configuration instructions allow to define details of the operation of the radio frequency identification (RFID) reader. With reference to Figures 3a to 3c, schematic diagrams of the main components that allow concurrent communication operations according to one embodiment of the present invention are shown. The host system is operated by the user by means of a user interface (Ul) 30, by means of which the user is allowed to have access to the functions of the guest system (for example, the portable terminal 100). In view of the multi-radio operation, the control exercised by the user through the user interface (Ul) 30 is carried out through the control programmer 200, which is interposed between the cellular communication subsystem 180 and the radio frequency identification (RFID) reader subsystem 190. The arrangement of the control programmer 200 makes it possible on the one hand to obtain information about the actual radio communication operations carried out by means of the cellular communication subsystem 180 as well as the subsystem radio frequency identification (RFID) reader 190 and on the other hand provide this obtained information and user inputs through the user interface to the programming algorithm to enable concurrent multi-radio operation. In analogy, the control can also be exercised by an application 35, which makes it possible to control the operation of the cellular communication subsystem 180 and the radio frequency identification (RFID) reader subsystem 190 through the control programmer 200. In detail, the Figures 3a to 3c illustrate different antenna arrangements including separate antennas 181 and 194 for the cellular communication subsystem 180 as well as the radio frequency identification (RFID) reader subsystem 190, a common antenna 182 coupled to both the cellular communication subsystem 180 and to the radiofrequency identification (RFID) reader subsystem 190 and a common antenna 182 coupled to both subsystems 180, 190 by means of a switch 196. The common antenna 182 is preferably an antenna of several frequencies, that is, an antenna whose characteristics are adapted to several frequency bands. These antennas are for example known in the field of dual and triple band GSM terminals. With reference to the implementation shown in Figure 3b, frequency bandpass filters (not shown) can be included in the signal path between the antenna 183 and the cellular communication subsystem 180 as well as the radio frequency identification reader subsystem ( RFID) 190 for separating RF signals received by the antenna 183 in such a way that the frequencies of different frequency bands are supplied to the respective subsystem 180 or 190 according to the corresponding radio frequency operating bands. With reference to the implementation shown in Figure 3c, an RF switch 196 is arranged to selectively couple the common antenna 182 to any of the subsystems 180 and 190 in accordance with a time-aligned operation thereof. The RF switch 196 can also be implemented as a tuneable bandpass filter circuit. The signal for adjusting the tunable bandpass circuit is provided by the control programmer 200. The proposed signal separation with reference to FIG. 3c is suitable for RF circuits of the cellular communication subsystem 180 as well as for the identification reader subsystem. by radio frequency (RFID) 190 since the RF signals "generated by one of the subsystems 180 or 190 do not apply to the respective other one.In particular, the implementation illustrated schematically in Figure 3c knows the requirement to program the operation of both subsystems 180 and 190 in a time-aligned manner The common antenna 182 is selectively coupled to any of the subsystems 180 and 190. The reception of RF signals and RF signal emission is operable with either the cellular communication subsystem 180 or the subsystem Radio Frequency Identification Reader (RFID) 190, respectively, Programmer 200 can be arranged separately e of the subsystems 180 and 190, the scheduler 200 can be implemented together with the subsystems 180 and 190 within a multi-radio communication subsystem, the scheduler 200 can be implemented based on one or more individual hardware and / or software components and / or these programming components can be part of the terminal 100, the cellular communication subsystems 180 or the radio frequency identification (RFID) reader subsystem 190. With reference to FIG. 4a, a sequence of total operation of the algorithm of programming according to one embodiment of the present invention. The operational sequence although illustrated as a linear sequence should be understood as the core of a monitoring circuit algorithm, which is carried out repeatedly in time. Based on the operation of the monitoring circuit and the ability to obtain information about the actual cellular operation frequency of the cellular communication subsystem 180, control is exercised over the radio frequency identification (RFID) reader subsystem 190. Programmer 200 is it is preferred to carry out the following operations when a user or application requests the operation of the radio frequency identification (RFID) reader subsystem 190. In operation S100, the actual frequency band is determined at which the cellular communication subsystem 180 currently operates. The determination of the actual frequency band is carried out regardless of whether the portable terminal currently operates in a fixed operating state or in an active operating state. It should be noted that the terms "fixed operation state", "operating state at rest" and "active operation status" refer to the operation in relation to the operative capacity of the cellular communication subsystem 180. In particular, a fixed / standby operating state designates a mode of operation of the cellular communication subsystem 180 in which location and measurement operations are carried out but no data or voice communication is carried out through the cellular communication subsystem 180. In the active operating state, the data and / or voice communication is carried out by means of the cellular communication subsystem 180 with the Radio Access Network (RAN) of the Public Land Mobile Network (PLMN), a which is subscribed cellular subsystem. In step S110, it is checked whether the cellular communication subsystem 180 is currently operated in the 850 MHz or 900 MHz frequency band (see definition of frequency bands given above). In case the cellular interface operates to another frequency band that is adequately separated from the UH frequency used by the radio frequency identification (RFID) reader subsystem 190, it can be assumed that a concurrent operation of both the cellular communication subsystem 180 and of the Radio Frequency Identification Reader (RFID) subsystem 190 is operable with reduced interference. The operational sequence branches to operation S220, where concurrent operation is allowed. However, it should be noted that the permission of a concurrent operation is simply possible in conjunction with an implementation of RF circuits that makes possible the concurrent reception and emission of RF signals at different frequencies as illustrated by the manner of illustration with respect to Figures 3a and 3b. Primarily, an implementation of RF circuits such as the one incorporated with reference to FIG. 3c does not make this concurrent operation possible. In such a case reference should be made to the time alignment, which will be described below with reference to the operations S160 to S230. In practice, almost all cellular terminals, which are currently on the market and which will be on the market in the future, are at least multi-band terminals or, preferably, multi-band terminals and multi-systems. Terminals that conform to typical cellular GSM support communication GSM 900/1800, communication GSM 850/1800/1900. Furthermore, the most recent cellular multi-system terminals support GSM 900/1800/1900 communication and WCDMA 2100 communication (UMTS). The same applies to cell terminals that support CDMA, for example, cell terminals activated by cdma2000 that support CDMA communication 850/1900 and are examples of available frequency combinations. Note that the cell terminals specified above are described by way of illustration; the present invention is not limited to any terminal of multi-systems and / or specific cellular multi-bands. Thus, portable terminals 100 may request to execute their cellular transmissions and receptions in a fixed or active operating state at frequencies outside 860-960 MHz or at least in a frequency band that is separated at a suitable distance at least in the case of UHF radio frequency identification (RFID) communication operationally. In case the cellular communication subsystem 180 operates on 850 MHz or 900 MHz radio frequencies, it is determined whether a radio frequency band transfer can be achieved in operation S130. The transfer can be an intra-system and / or inter-system transfer. The transfer operations must be reachable by the portable terminal 100 and the cellular communication subsystem 180, respectively. Intra-system transfer should be understood as a transfer to another frequency band while preserving the cellular system standard currently operated, for example, from GSM 850 (EUA) or GSM 900 (Europe) to GSM 1800 (Europe) and GSM 1900 (USA), respectively. Inter-system transfer should be understood as a transfer to another cellular system standard that typically includes a frequency band transfer, for example, from GSM 900 (Europe) to WCDMA 2100 (Europe or from GSM 850 (EUA) to cdma2000 (USA) Inter-system transfer can also be designated protocol transfer It should be noted that the requirements and needs to carry out intra-system transfer procedures as well as inter-systems must be considered. resources of frequency, availability of PLMNs that support the desired cellular system standard, provider that gives limitations and regulations of use, have to be taken into account The details about the requirements can be derived from transfer procedures defined in the respective cellular standards. It should also be noted that a protocol transfer from a GSM-CDMA-based system started at the request of the terminal 100 (and the cellular communication subsystem 180, respectively) may require adaptation of the current standards to make this protocol transfer possible. In particular, the GSM system does not specify an application allowing a cellular terminal to request a frequency band transfer in a fixed or active operating state. The invention introduces this transfer procedure that includes the request and response framework after the start of the portable terminal 100 capable of cellular communication. The inclusion of this protocol transfer according to the embodiment of the present invention is proposed herewith. In case the transfer is successfully achieved, the operational sequence branches to operation S220. Note that the comments mentioned above about the concurrent operation and about allowing the concurrent operation apply as well.

In step S140, the radio frequency output power of the radio frequency identification (RFID) reader subsystem 190 is reduced. The reduction of the RF output power can achieve a reduction in the level of interference. In step S150, the level of interference consequent to the reduced RF output power of the radio frequency identification (RFID) subsystem is determined. In case the interference level is below a predefined threshold, the concurrent operation can be allowed in the operation S220. Note that the comments mentioned above about the concurrent operation and allowing the concurrent operation also apply. The defined threshold may depend on priority considerations (prioritization of the cellular communication subsystem 180 or the Radio Frequency Identification Reader (RFID) subsystem 190), considerations of quality of service (bandwidth requirements, freedom or interruption) and types of communication (e.g., data packets, voice or communication by data streams currently operated by means of the cellular communication subsystem 180, and the like.) Otherwise, operation S160 is checked if the time-aligned operation of the communication subsystem cellular 180 or the radio frequency identification (RFID) reader subsystem 190 is permissible, in particular, based on the operational profile of the cellular communication subsystem (eg, GSM, cdma2000 and WCDMA, respectively) and the values related to the operation RF of the radio frequency identification subsystem (RFID), it is derived if it is an operation of iden Radio frequency (RFID) timing aligned in time in coordination with the cellular communication operation (either in the steady state / standby state or in the active operating state) is permissible. The possibility of time alignment depends on several conditions, including in particular whether the cellular communication subsystem 180 operates in the fixed / idle state of operation or in the active operating state and more particularly, in the case of the active mode of operation if the Communication mode allows alignment by time. Those skilled in the art will appreciate that the decision as to whether the time aligned operation is possible or does not require a closer consideration of the different cellular rules introduced above. The details about it will be illustrated in the following operational sequence described below with reference to Figure 4b. In step S170, according to the result of the revision operation S160, the time alignment operation can be denied or allowed. After the negation, the operational sequence branches to operation S210, where for example the user is informed that the concurrent time alignment operation is not available, respectively. Otherwise, the operational sequence is continued with the operation S180, wherein the operation mode of the cellular communication subsystem is determined and depending on the mode of operation, the operational sequence branches to either operation S190 or operation S200 for enabling an operation aligned in time in fixed operation mode as well as in active operation mode of the cellular communication subsystem. Details about the circuit operation in the fixed operating state (S190) and the circuit operation in the active operating state (S200) can be elaborated in more detail with reference to FIGS. 4c and 4d, respectively. In the operation S230, which follows the circuit operation in the fixed operating state (S190) and the circuit operation in the active operation state (S200), a selective repetition of the revision can be carried out for aligned operation by weather. In case this repetition is desired, the operational sequence returns to operation S160. A selective repetition may be adequate in view of a changing mode of operation and / or mode of operation of the cellular communication subsystem. More details will be apparent when the following description is read.

With reference to Figure 4b, the revision for time-aligned operation according to an embodiment of the present invention is carried out in more detail. In addition, reference will be made to the details that refer to different cellular rules. In operation S240, the operating mode of the cellular communication subsystem is obtained. The operating mode can be a fixed operation / standby state or active operation state. In step S245, the operational sequence is ramped depending on the determined mode of operation of the cellular communication subsystem. In the case that the operation mode is the fixed operation state, the time aligned operation is permissible according to the operation S295. The review operation is concluded. An excuse should be given in the following paragraphs to the operations of the cellular communication subsystem during the fixed / standby mode of operation. Reference will be made to the cellular rules mentioned above.

GSM, GSM / GPRS, GSM / EDGE: In the case of GSM, GSM / GPRS, GSM / EDGE, the cellular system uses time division multiple access (TDMA) (in addition to frequency division multiple access; FDMA) for separating data and / or voice communication between different cell terminals within a cell and / or between adjacent cells. Accordingly, basically all communication operations are carried out in a segmented manner by strict synchronizations, i.e., the well-defined start and end synchronization of the data communication burst. Therefore, time frames with time segments are defined. The time segments are selectively assigned to one or more cellular terminals and channels. Consequently, each cellular terminal has its own determined intervals, within which transmission and / or reception is operable. In general, the cellular communication subsystem does not operate any data or voice communication during the fixed operating state except for location communication and related to measurement. In the fixed operation mode, a terminal enabled by GSM / EDGE listens for example to the Common Control Channel (CCCH) to discover possible location carried out by the radio access network (RAN), base station (BS), the node B or similar. The CCCH listener also ensures synchronization in frequency and time of the cellular communication subsystem. The CCCH is received and decoded according to a predefined DRX (discontinuous reception) period, that is, from one to two to one for nine 51 multi-frames (listening interval of approximately 0.5 s-2 s).

Typically, the listening interval in the CCCH is around 2 seconds. In addition, a minimum of seven adjacent cells are monitored each time a location is heard. The terminal does not transmit anything in the fixed mode of operation unless there is a need to do so. The need could be a call initiation according to a call originating for the user, a response to a call initiation request (indicated by means of a location message) according to the call terminated by the mobile station, an update of the call. periodic location, etc. In case there is no service in use, location updates are the only activities that require the transmissions carried out by the cellular communication subsystem of the portable terminal. Therefore, in general, during the fixed mode of operation, a terminal activated by GSM / EDGE listens to the CCCH for two to four segments in two seconds, and carries out the received signal level measurements for the adjacent cell of the network public land mobile (PLMN); that is, the base station (BS) of the adjacent cell. All other operations occur in a very similar way, and therefore the CCCH reception mainly determines the radio frequency identification (RFID) activity allowed in this case. Analogous considerations apply to GSM and GSM / GPRS in fixed operation mode. As a result, there are available periods of non-activity of the cellular communication subsystem during which communication by radio frequency identification (RFID) (UHF) can be carried out. In addition, the periods of activity of the cellular communication subsystem GSM, GSM / GPRS or GSM / EDGE in fixed operation mode and consequently also the periods of non-activity are well defined.

WCDMA and CDMA (cdma2000): Both cdma2000 and WCDMA (Broadband Broadband Code Access as well as UMTS) use CDMA (Code Division Multiple Access) as a multiple access method. The CDMA base is formed by signals modulated by scattered spectrum. A broad-spectrum modulated signal is typically continuous in nature and therefore the programming solution differs from the GSM, GSM / GPRS or GSM / EDGE case mentioned above. During the fixed operation mode, a terminal activated by cdma2000 listens to the Pilot Channel Forward (F-PCH) of its property and adjacent cells to detect messages directed to it and measure the pilot power to determine the need for a fixed transfer. In addition, the terminal activated by cdma2000 listens to the Localization Channel (PCH) to detect possible incoming calls.

It takes an average of about 100 ms to hear its own segment during the cycle length of the 2SCI F-PCH segment (SCI SLOT_CYCLE_INDEX) in units of 1.28 s (for example, SCI = 1 (2SCI = 2) in the US and SCI = 2 (2SCI = 4 in Japan, typically.) In case the cdma2000 PLMN supports Fast Forward Channel (F-QPCH) channel indicators, the terminal activated by cdma2000 listens to its F-QPCH indicator for about 20 ms. of the segmented page listener, which occurs approximately once per minute In IS-2000 edition A the fixed mode of operation is a bit different from the one described above The F-BCCH (Transmission Control Channel Forwards) contains header messages is only decoded when there is a need to access or when a new pilot is detected indicating a possible fixed transfer The F-CCCH (Common Control Channel Forward), which carries location messages to cellular terminals, is decoded when a location is detected in F-QPCH. In the case of a fixed WCDMA mode of operation the terminal activated by WCDMA is camped to a cell, listens to system information, location and notification messages and carries out regular measurements to find the most powerful base station (BS) signal and the adjacent base stations (BS, nodeB, etc.) also. The signal levels of the service call are measured at least every DRX cycle (discontinuous reception) (from 0.64 s to 5.12 s in the fixed operation state). There are also cell measurements between frequencies (with a measurement cycle of 1.28 s and 5.12 s in the fixed operating state) and inter-frequency cell measurements (each frequency in each (Ncarr? Er-1) * 1.28 s (Ncarrler- 1) * 5.12 s cycle). The location comprises listening to BCH and PCH transport channels sent in P-CCPCH (Primary Common Control Physical Channel) and S-CCPCH (Secondary Common Control Physical Channel), respectively. The terminal activated by WCDMA can also send the discontinuous reception (DRX) in the fixed operation state, and in that case the terminal activated by WCDMA only has to monitor a location indicator from the location indicator channel (PICH). This occurs once every DRX cycle. Naturally, if the terminal initiates a call (call originated in terminal), a message is sent in the RACH (Random Access Channel). As a result, there are periods of non-activity available from the cellular communication subsystem during which radio frequency identification (RFID) (UHF) communication can be carried out. Furthermore, the activity periods of the CDMA or WCDMA cellular communication subsystems in fixed operation mode and consequently also the periods of non-activity are well defined. Referring again to Figure 4, in case the mode of operation is the active operating state and the ability to allow over time-aligned operation or to deny the time-aligned operation requires a more detailed consideration of the different cellular system standards. In operation S250, it is checked whether the cellular communication subsystem can operate with GSM, GSM / GPRS or GSM / EDGE communication and, in case the revision coincides, it is determined if the allocation of time segments makes the time aligned operation possible. As mentioned above, a cellular system activated by GSM, GSM / GPRS or GSM / EDGE uses time division multiple access (TDMA) (in addition to frequency division multiple access (FDMA)) to separate data communication and / or voice between different cell terminals within a cell and / or between adjacent cells. Consequently, basically all communication operations are carried out in a segmented manner with strict synchronizations, that is, the start and end synchronization of the data communication burst is well defined. This means, the decision of permission or denial of an operation aligned in time has to consider whether the time segments are available in which the cellular system is inactive (ie, inactive in the means that one or more segments of a table are not assigned to the transmission or reception of data). During a voice call or GPRS data call the cellular communication subsystem is active during its uplink and downlink segments of the TDMA (Time Division Multiple Access) frame, which are assigned for each data uplink as well as for data downlink transmission. There could be more than one segment assigned to the cellular communication subsystem in both directions (uplink and downlink). In addition, the cellular communication subsystem monitors the adjacent base stations (BS, nodeB, etc.) once in a TDMA frame (comprising eight time segments), one base station at a time. According to the concept of the present invention, the radio frequency identification (RFID) reader subsystem placed with a GSM, GSM / GPRS or GSM / EDGE cellular communication subsystem has to prevent the transmission of carrier waves during the active periods of the subsystem of cellular communication as mentioned above. In accordance with one embodiment of the present invention, FIG. 5a representatively illustrates the activity diagram of the GSM / EDGE subsystem operated in a time aligned manner with a radio frequency identification (RFID) reader subsystem. In particular, the activity diagrams illustrate activity states in the case of a Dual Transfer Mode (GSM / EDGE (DTM) case illustratively showing the interleaving of the activity periods of both subsystems.) Figure 5a illustrates an assignment of two time segments (time segments RX # 1 and # 2) for downlink communication (RX) and a time segment (time segment TX # 2) for uplink communication (TX). in a TDMA frame (comprising time segments # 0 to # 7) one of the adjacent base stations (BS, nodeB, etc.) monitored based on a measurement operation, the measurement operation is interposed exemplarily between the segments of time # 4 and # 5 with respect to the TDMA structure of the uplink communication channel It should be noted that the allocation of uplink and downlink time segments is exemplary; only assignments of time segments for uplink communication and / or downlink communication can be used. According to the uplink and downlink communication as well as the measurement operation, two periods of non-activity per TDMA frame can be identified; that is, a first period of non-activity (substantially comprising time segments # 0 and # 1) interposed between the downlink operation and the uplink operation and a second period of non-activity (substantially comprising the segment of time TX # 3 and a part of the time segment TX # 4) interposed between the uplink operation and the measurement operation. These periods of non-activity of the cellular communication subsystem are applicable to operate the radio frequency identification subsystem (RFID) as exemplified in Figure 5a with respect to the CW (continuous wave) of RFID reader operation. The trained reader understands based on the illustration of Figure 5a that depending on the allocation of time segments in TDMA systems one or more periods of non-activity may be available within the segmented time structure. These periods of non-activity of the cellular communication subsystem are applicable to operate in the radiofrequency identification subsystem (RFID) without having the fear of suffering interference generated by the cellular communication subsystem and the radio frequency identification subsystem (RFID). It should also be noted that the allocation of time segments for uplink and downlink communication may be requested by the cellular communication subsystem of the terminal. As a result, an adequate allocation of time segments can be requested to obtain periods of non-activity which makes possible a time-aligned operation of both subsystems. The request for an appropriate time slot allocation may be accompanied by a downlink and / or downlink data rate of the cellular communication subsystem but adequately makes the time aligned operation possible. As a result, depending on the operation assigned by time by allocation of time segments of both subsystems can be allowed or rejected. In the first case of permission, the operational sequence continues with operation S295, while in the second case of rejection, the operational sequence continues with operation S290. In step S290, the time-aligned operation is denied. In step S260, it is checked whether the cellular communication subsystem can operate with WCDMA communication and, in case the revision coincides, it is determined if the communication mode is applicable with the operation aligned in time, in step S265. As mentioned above, WCDMA (Multiple Access by Division of Broadband Codes such as UMTS uses CDMA (Multiple Access by Code Division) as a multiple access method. The base of CDMA is formed by modulated signals of broad spectrum. A broad-spectrum modulated signal is typically continuous in nature, and therefore the programming solution differs from the case (GSM, GSM / GPRS or GSM / EDGE mentioned above.) While having a voice or data call in the mode of WCDMA active operation, the cellular communication subsystem can use compressed mode to enable an apparently concurrent radio frequency identification reader (RFID) reader operation.Reference should be made to Figure 5b, which illustrates an exemplary time structure of a communication in compressed mode Although WCDMA uses CDMA (Code Division Multiple Access) methodology as a multiple access method, time multiplexing is equally applied to different channels separated in the physical layer.The structure of multiplexing by time is typically based on a structure of time frames, where each time frame comprises 15 time segments, in compressed mode (or segmented) the base station (BS, nodeB, etc.), to which the cellular communication subsystem communicates, allocates transmission spaces both in downlink and uplink to enable inter-cell measurements carried out by the subsystem of cellular communication of the terminal. These inter-cell measurements are required for the inter-frequency transfer of a cellular communication subsystem of the terminal and are carried out on the different carrier frequencies of WCDMA. Several time segments can be assigned to carry out this measurement. These assigned segments can be either in the middle of a single frame or scattered over two frames. To enable the operation of a radio frequency identification (RFID) reader, some or all of the assumed measurements that are carried out by the terminal (and the subsystem thereof, respectively) are skipped to leave sufficient time of non-applicable activity for the operation of the radiofrequency identification subsystem (RFID). Transmission Space Length (TGL) and synchronization are determined by the cellular Radio Access Network (RAN). Compressed tables are simultaneous in both uplink and downlink time. The specified Transmission Space Length (TGLs) is 3, 4, 7, 10 and 14 segments, that is, from 2 ms to 9.3 ms. Operation in compressed mode can be achieved in different methods including reducing the dispersion factor (for example in 2: 1), drilling bits (that is, resulting in a reduced amount of information that will be transmitted) or programming changed into layers higher (for example, that less time segments are required for communication). With reference to Figure 5b (1), in a compressed table the segments of #Nfirst to #Number that define the length of the transmission space are not used for data transmission. As exemplified, the instantaneous transmit power is increased in the compressed frame to thereby maintain the quality of service (Bit Error Rate, Frame Error Rate, etc.) unaffected by the reduced processing gain. The amount of increase in power depends on methods of reduction in transmission time illustrated above. The tables that will be compressed are indicated by the network. Mainly in compressed mode, compressed tables can occur periodically, or be ordered on demand. The speed and type of compressed frames is variable and depends on the environment and the measurement requirements. With reference to Figures 5b (2) - (4), different frame structures for uplink and downlink compressed frames are illustrated. Referring particularly to the structure of downlink compressed frames, there are two different types of frame structures defined. Type A (for example see 5b (3)) maximizes the Transmission Space Length (TGL), while type B is optimized for power control. The type A or B frame structure is established by higher layers regardless of the type of downlink segment format A or B. With the type A frame structure, the pilot field of the last segment of the transmission space is transmitted. The transmission is switched off for the rest of the transmission space. With the type B frame structure, the TPC field of the first segment in the transmission space and the pilot field of the last segment in the transmission space are transmitted. The transmission is switched off for the rest of the transmission space. Although in communication in compressed mode the Transmission Space Length (TGL) and its synchronization are determined by the cellular Radio Access Network (RAN), those skilled in the art will appreciate that provisions can be made to enable the cellular communication subsystem of the terminal to instruct the communication in compressed mode and determine its properties (length, synchronization). As a result, the communication in compressed mode can be requested by the terminal to obtain periods of non-activity which makes possible the aligned operation in time of both subsystems. The measurement operations originally arranged are omitted. The request for a communication in compressed mode can be achieved and can be accompanied by a downlink data rate and / or reduced downlink of the cellular communication subsystem but makes the time aligned operation suitably possible. As a result, depending on the time-aligned operation the communication mode of both subsystems can be allowed or rejected. In the first case of permission, the operational sequence continues with operation S295, while in the latter case of rejection, the operational sequence continues with operation S290. In step S290, the time-aligned operation is denied. In step S270, it is checked whether the cellular communication subsystem is operable with the cdma2000 communication and, in case the revision coincides, it is determined if the communication mode is applicable with time aligned operation, in the operation S275. As mentioned above, cdma2000 also uses CDMA (Code Division Multiple Access) methodology as a multiple access method. The base of CDMA is formed by modulated signals of broad spectrum. A broad-spectrum modulated signal is typically continuous in nature, and therefore the programming solution differs from the GSM, GSM / GPRS or GSM / EDGE case mentioned above. The terminal activity activated by cdma2000 is generally continuous while in the active operating state. The only exception is the Discontinuous Transmission (DTX) mode. In Discontinuous Transmission (DTX) mode, the cellular communication subsystem activity of the terminal is only 50% of the nominal value in the reverse link (ie, uplink address). Similarly, there is also a discontinuous transmission available for the forward link (i.e., the downlink address). These spaces in uplink and downlink transmission and reception could be used to enable the radio frequency identification (RFID) operation. However, it should be noted that the mode of Discontinuous Transmission (DTX) is only allowed in F-DCCH (Dedicated Forward Control Channel in cdma2000) and R-DCCH (Dedicated Backward Control Channel), but voice data can not be transferred in those channels. If necessary, the Discontinuous Transmission mode (DTX) can be requested by the terminal activated by cdma2000. The communication request in the Discontinuous Transmission (DTX) mode may be accompanied by a downlink data rate and / or reduced downlink of the cellular communication subsystem but makes the time aligned operation possible. As a result, depending on whether Discontinuous Transmission Mode (DTX) is available and applicable, the time-aligned operation of both subsystems can be allowed or rejected. In the case of permission, the operational sequence continues with operation S295, while in case of rejection the operational sequence continues with operation S290. In step S290, the time-aligned operation is denied. Those skilled in the art will appreciate that the concept of the present invention described on the basis of the TDMA-based cellular communication subsystems incorporated and mentioned above and the CDMA-based cellular communication subsystems is also applicable with other communication subsystems to base of TDMA and CDMA, respectively. This means that the programming of a radio frequency identification (RFID) reader subsystem according to one embodiment of the present invention should not be limited to the cellular communication subsystems mentioned above. In general, periods of non-activity are commonly provided in wireless communication systems to enable the reduction of the power consumption of the respective wireless communication subsystem. The consideration of energy consumption refers especially to portable terminals (such as terminal 100), which are supplied for batteries and / or accumulators that provide only a limited total energy capacity. During periods of non-activity, wireless communication subsystems can be turned off or at least operated in energy-saving modes. In view of the aforementioned description of the needs and constraints required to enable the time aligned operation of the cellular communication subsystem and the Radio Frequency Identification Reader (RFID) subsystem, reference should now be made to Figure 4c which shows schematically an operational sequence of the circuit method in steady state / standby state according to an embodiment of the present invention. The procedure of the fixed operation / standby state circuit is part of the complete operational sequence described above with reference to Figure 4a. Typically during the fixed / standby mode the cellular communication subsystem of the terminal listens to the location messages coming from the PLMN and base station (BS, nodeB, etc.), respectively, to know if a communication connection will be established . Accordingly, when the cellular terminal activated by radio frequency identification (RFID) is turned on or the functionality of the radio frequency identification (RFID) reader of a cellular terminal is activated, the timing of the operation aligned in time starts to operate in accordance with the following monitoring circuit operations according to one embodiment of the present invention. In operation S300, when the cellular communication subsystem is set to the Radio Access Network (RAN) or the base station (BS, nodeB, etc.), or later regularly during the fixed / idle state, the subsystem of The cellular communication receives one or more system information messages which include information about the location group, to which the cellular communication subsystem is assigned, and therefore also the location synchronization. In step S310, when the cellular communication subsystem is set to the Radio Access Network (RAN) or the base station (BS, nodeB, etc.), or later regularly during the fixed / standby state, the subsystem of The cellular communication also receives synchronization information from system information messages about measurements of potential signal levels from adjacent base stations. In the S320 operation, after obtaining the information that refers to the location cases as well as the information that refers to the measurement cases, the information is provided to the programmer. Based on the synchronization information about the location instants and programming instants, the programmer is synchronized to the location and measurement synchronization in such a way that exact location and measurement instants and their lengths are known. As a result, the programmer is informed about the exact synchronization of the periods of activity and non-activity of the cellular communication subsystem; in particular, synchronization of the start and end of the activity and the periods of activity and non-activity of the cellular communication subsystem. In step S330, the additional configuration of the programmer and / or radio frequency identification reader subsystem (RFID) is operable. The following description should be referred to. In step S340, the operation of the radiofrequency identification (RFID) reader subsystem can be initiated. The start can be caused after the reception of a user input in the terminal or after a start signal generated by an executable application in the terminal. After the indication starts, the operational sequence continues with operation S350, otherwise the operational sequence branches to operation S360. In step S350, the programmer aligns the operation timing of the radio frequency identification reader (RFID) in such a way that the operation is carried out during periods of non-activity of the cellular communication subsystem. The periods of non-activity are determined based on the information that refers to cases of location as well as information that refers to the measurement cases (see operation S320). In an S360 operation, it is checked whether new information that relates to the timing of the time-aligned operation (ie, location instances and information related to location instances and / or information related to measurement instances) is available, for example, of system messages received from the Radio Access Network (RAN) by the cellular communication subsystem of the terminal. In case new information is available, the operational sequence returns to operation S300, otherwise the operational sequence continues with operation S370. In step S370, the time-aligned operation of the radiofrequency identification subsystem (RFID) can be carried out repeatedly. The operational sequence can be returned to operation S340 or operation S350, when for example the operation of the radio frequency identification (RFID) subsystem is divided into individual radio frequency identification (RFID) subsystem operations. It should be noted that the mode of operation of the cellular communication subsystem may change. This means that, after the indication of the radio access network (for example, location message, mobile terminated call start message, etc.) or in response to a user request (e.g. mobile call) the cellular communication subsystem can change from fixed operation / sleep mode to active operation mode. In case of a change from operating mode to active operation mode the operational sequence may return to S160 described with respect to figure 4a, to check the possibility of operation aligned in time in the active operation mode. In view of the aforementioned description of the needs and constraints required to enable the time aligned operation of the cellular communication subsystem and the Radio Frequency Identification Reader (RFID) subsystem, reference should also be made to Figure 4d, which schematically shows an operational sequence of active operating state circuit procedure according to an embodiment of the present invention. The active operation state circuit procedure is part of the total operational sequence described above with reference to FIG. 4a. In case of active operation status (ie, either voice call or data call currently carried out) or states that require a similar type of activity to the actual active operating status (eg, GSM ready state / GPRS), the operation of the radiofrequency identification subsystem (RFID) has to be programmed in such a way that an overlap with the activity of the cellular communication subsystem is avoided. In accordance with one embodiment of the present invention, the active operation status includes the following operations. In operations S400 and S410, the standard and mode of communication as well as information related to synchronization of activities are obtained. In particular, when the terminal enters the state of active operation (or similar), or subsequently regularly during the active operating state, the standard and mode of communication (GSM, GSM / GPRS, GSM / EDGE, WCDMA compressed mode, cdma2000 , DTX mode, etc.) and the information returned with activity synchronization of the cellular communication subsystem are determined. Information related to activity synchronization includes especially the synchronization of active segments in case of GSM, GSM / GPRS, GSM / EDGE synchronization, TGL in WCDMA compressed mode, or Discontinuous Transmission synchronization (DTX) in cdma2000 is obtained from the subsystem of cellular communication. Reference should be made to the description given above with reference to Figure 4b. In operation S420, after obtaining the information related to synchronization, the information is supplied to the provider. Based on the synchronization information about the moments of location of instants of measurement, the programmer is synchronized based on the information related to synchronization in such a way that the periods of non-activity and their lengths are known. As a result, the programmer is informed about the exact synchronization of activity periods and non-activity of the cellular communication subsystem; in particular, the synchronization of start and end of activity periods and non-activity of the cellular communication subsystem. In step S430, additional configuration of the programmer and / or radio frequency identification (RFID) reader subsystem is operable. The following description should be referred to. In step S440, the operation of the radio frequency identification (RFID) reader subsystem can be initiated. The start may be caused after the receipt of a user input to the terminal or after a start signal generated by an executable application in the terminal. After the indication to start, the operational sequence continues with operation S450, otherwise the operational sequence branches to operation S460. In operation S450, the programmer aligns the operation timing of the radio frequency identification (RFID) reader in such a way that the operation is carried out during periods of non-activity of the cellular communication subsystem. The periods of non-activity are determined based on information related to synchronization (see step S420). In an operation S460, it is checked whether new information related to the programming of the time-aligned operation (that is, information related to location instances and / or information related to measurement instances) is available, for example, from messages of systems received from the Radio Access Network (RAN) by the cellular communication subsystem of the terminal. In the event that new information is available, the operational sequence returns to operation S300, otherwise the operational sequence may continue with operation S470. In step S470, the time-aligned operation of the radio frequency identification (RFID) subsystem can be carried out repeatedly. The operational sequence can be returned to operation S440 or operation S450, when for example the operation of the radio frequency identification (RFID) subsystem is divided into several operations of the individual radio frequency identification (RFID) subsystem. It should be noted that the operation mode of the cellular operation subsystem may change. This means that after the indication of the Radio Access Network or in response to a user request the cellular communication subsystem can change from an active operation mode to a fixed operation / rest mode. In the case of a change from the operation mode to a fixed operation / rest mode, the operational sequence can be returned to S160 described with respect to figure 4a, in order to return the possibility of an operation aligned in time in the fixed operation mode / rest or can branch directly to step S300 described with respect to figure 4c. The description mentioned above of the programming algorithm focuses on the requirements that have to be satisfied to make possible a main time alignment of both subsystems. Next, an optimized operation of the radio frequency identification (RFID) reader subsystem will be described. The optimization is adequate to enable an effective operation of the Radio Frequency Identification Reader (RFID) subsystem within periods of non-activity, during which the operating capacity is permissible. In accordance with one embodiment of the present invention, a configuration and control interface, preferably an application program interface (API), is provided to control and configure the operation of the radio frequency identification (RFID) reader subsystem. The configuration and control interface for the radio frequency identification (RFID) reader subsystem can be achieved by the exchange of data and commands through the data interface of the Radio Frequency Identification Reader (RFID) subsystem. It should be noted that the specific activation and / or digital signal terminal mentioned above that can be used to synchronize the operation of the Radio Frequency Identification Reader (RFID) subsystem can be implemented as a separate signal input terminal to the revision logic of the reader subsystem. Radio Frequency Identification (RFID) or as an alternative, the activation signal can be supplied to the logical reviewer of the radiofrequency identification (RFID) reader subsystem through its data interface, too. A terminal of separate activation signals may be preferred to thereby ensure synchronization with the activation signal. The configuration capability of the radio frequency identification (RFID) reader subsystem is preferably under the control of the programmer, which also activates the operation of the radio frequency identification (RFID) reader subsystem. Reference should be made back to operations S330 and S430 of the circuit procedures of fixed and active mode of operation, respectively. In general, the programming mechanism described in detail above uses information related to synchronization to identify periods of activity and non-activity of the cellular communication subsystem in such a way that the programmer prevents the radio frequency identification (RFID) reader subsystem from operating. the cellular communication subsystem works, that is, while the cellular communication subsystem for example receives location messages, carries out measurements, sends or receives data packets, or sends bursts of random access data. Among others, the programmer is willing to configure the maximum duration of a single RF emission so that it is not greater than a period of non-activity of the cellular communication subsystem and triggers the operation of the Radio Frequency Identification Reader (RFID) subsystem in correspondence with expected start of the period of no activity. The programmer may use the specified digital I / O activation signal terminal to activate the synchronized RF activity of the radio frequency identification (RFID) reader subsystem. Reference should be made to Figure 6a, which exemplarily illustrates a time-of-activity sequence based on the GSM / EDGE DTM activity diagram shown in Figure 5a according to one embodiment of the invention. For reasons of illustration, a first period of activity? and a second period of activity are still identified as a first period of non-activity? and a second period of non-activity? nn are identified. According to the periods of non-activity, periods of RF signals from the Radio Frequency Identification Reader (RFID) subsystem are indicated as RFID Reader RF Activity Windows (see legend in Figure 6a) meaning an RF broadcast, in accordance with the level of signal strength, accuracy and integrity requirements, of the radio frequency identification (RFID) reader subsystem antenna. An optimized time to establish the activation signal to initiate the RF activity of the Radio Frequency Identification Reader (RFID) subsystem is a duration At, which represents an ascending ramp duration? I. The ascending ramp duration At is required by the radiofrequency identification reader subsystem (RFID) from receiving the activation signal to start transmitting an RF signal in accordance with the signal power level, accuracy and integrity requirements of the radio frequency identification (RFID) reader system, of the reader subsystem antenna of radio frequency identification (RFID). Among others, the up-ramp duration? I is caused by a PLL (Phase Circuit Safe) setting, microcontroller / logic warming, RF interface establishment time and / or other needs before RF activity.

Preferably, an additional guard duration? P should be considered between the end of the activity period of the cellular communication subsystem and the beginning of the emission of RF signals from the radiofrequency identification reader subsystem (RFID). When considering the ascending ramp duration At and the guard duration p, the activation signal that initiates the operation of the radiofrequency identification reader subsystem (RFID) must be adjusted? -? H before an end of a period of activity of the cellular communication subsystem. When a reference point is arbitrarily defined at time 0 coinciding with an end of a period of activity as well as the beginning of a period of non-activity of the cellular communication subsystem, the activation signal must be established at a point in time Tz =? p- ?? < 0. The emission of an RF signal from the radio frequency identification (RFID) reader subsystem starts correspondingly at a point in time Tu? P > 0, which is equal to the guard duration? P. Optimized time for restoration (release) of the activity signal to stop the RF activity of the Radio Frequency Identification Reader (RFID) subsystem is a duration Am, which represents a down-ramp duration Am, The down-ramp duration? p is required by the radio frequency identification (RFID) reader subsystem from detecting the restart of the activation signal until the RF signal emission generated by the radiofrequency identification (RFID) reader subsystem. The RF emission will be terminated before the start of the activity of the cellular communication subsystem, and therefore also before the time instant 0 'and the end of the Ara period. In contrast to the ascending ramp duration? I, there is no need to ensure sufficient establishment times of the PLL (phase locked circuit), RF interface, etc. during? m at the end of the RF activity, since the accuracy and integrity of the power level of the RF signal is not relevant as long as the output stage is deactivated and there is no RF emission from the antenna of the reader subsystem. radio frequency identification (RFID). When the descending ramp duration A is considered, the restart of the activation signal that terminates the operation of the radio frequency identification (RFID) reader subsystem must be set to Am before an end of a period of non-activity of the cellular communication subsystem. . When a reference point is arbitrarily defined at time 0 'coinciding with an end of a period of non-activity as well as the beginning of a period of activity of the cellular communication subsystem, the activation signal must be established at a point in time Tm = -Am < 0 '. Thus, the emission of an RF signal ends correspondingly during a period of time ending before a reference point at time 0 ', in such a way as to avoid interference with cellular activity. Those skilled in the art will appreciate that the period of operation of the radio frequency identification (RFID) reader subsystem can be optimized by adjusting the guard duration? P and considering the up-ramp duration At as well as the down-ramp duration? I. The ascending ramp duration? I as well as the descending ramp length m are typically specific to the radio frequency identification (RFID) reader subsystem used. Additional parameters of the Radio Frequency Identification Reader (RFID) subsystem can also make it possible to adjust and / or optimize the operation of the Radio Frequency Identification Reader (RFID) subsystem. An optimization and adjustment of the radio frequency identification reader (RFID) subsystem operation is adequate to effectively use periods of non-activity of the cellular communication subsystem and adjust the operation of the radio frequency identification (RFID) reader subsystem to the specific lengths of periods of non-activity. The adjustment and / or optimization may include the modification of some of the parameters of the Radio Frequency Identification Reader (RFID) subsystem.

Static information: The programmer must be informed about at least one sleep clock cycle of the Radio Frequency Identification Reader (RFID) subsystem and the duration of the up and down ramp required before the RF activity and after the RF activity of the RF radio frequency identification (RFID) reader subsystem. Also the information that refers to minimum, predetermined and maximum values as well as units of additional parameters, which are listed below, must be available in the programmer. This information is typically described by the manufacturer of the radio frequency identification (RFID) reader subsystem used in a data sheet. The information is preferably stored in the programmer or stored in the terminal to be accessible by the programmer when required. Information related to semi-static standard: Among others, the programmer can obtain and optionally modify the following parameter values that are relevant to the duration of RF activity. Reference should be made to the EPCglobal generation 2 standard. The following parameters may be relevant and will be described with reference to figures 6b to 6d. With reference to Figure 6b, the activation as well as the RF envelope deactivation of the interrogation RF signal is illustrated. Reference should be made to the above-mentioned description of the ascending ramp duration and descending ramp duration. The time of origin Tr and flow time Tf illustrated in Figure 6b comprise the ascending ramp duration At and descending ramp duration? M. However, it should be noted that Figure 6b simply illustrates the envelope of the detectable RF signal at the RF interface of the Radio Frequency Identification Reader (RFID) subsystem. The time of origin Tr and time of calflow Tf must be within the time scale of 1 μs to 500 μs. After activation, the interrogation signal requires an establishment time Ts before being substantially at a constant level (100% energy level). The establishment time Ts must be within the time scale from 0 to 1,500 μs. During activation, the envelope must originate monotonically when exceeding the power level of 10% to at least the ripple limit M (power level of 95%). During deactivation, the envelope must be monotonically reduced when it falls below the 90% power level to at least the power of the Ms limit (1% power level). The power levels Mi (undershoot, maximum 95%) and Mh (overshoot, maximum 105%) define the limits of power levels of the RF envelope. It should be noted that in some regions an attempt has to be made to detect carriers before starting radio frequency identification (RFID) communication. For example, with regard to the regulations of the ETSI (European Telecommunications Standards Institute), which have especially been considered in Europe, the use of radio frequency identification (RFID) communication for example at a frequency scale of 865 MHz to 868 MHz presupposes a so-called "Listen Before Speaking" operation (LBT). The Listen Before Speech (LBT) operation is provided to detect if a different frequency subband destined for radio frequency identification (RFID) communication is currently busy or free (unoccupied). The detection must avoid the collision of communications in the same radio frequency sub-band. For example, according to the specifications of the ETS, immediately prior to each communication by a radio frequency identification (RFID) reader subsystem, the radio frequency identification (RFID) reader subsystem has to be passed to a so-called listening mode in which one or more preselected frequency sub-bands are monitored during a specific listening period, which will also be designated as the TLSB bearer detection period- The bearer detection period T SB (for example according to the ETSI regulations) must comprise a fixed time interval, for example 5 ms and a time interval random, for example, in the time scale of 0 ms ar ms, in particular in the time scale from 0 ms to 5 ms. In case the monitored subband is free (unoccupied), the random time interval is set to 0 ms. The ETSI specifications further define certain minimum levels allowed for threshold levels, which define sensitivity characteristics. These minimum allowable levels depend on the level of transmission power intended to be used in radio frequency identification (RFID) communication. Note that the TLSB variable carrier detection period (equal to a variable time period in the time scale from 5 ms to 10 ms) should also be considered when adjusting and / or optimizing the operation of the radio frequency identification reader subsystem (RFID) With reference to Figure 6c, the data encoding in physical layer is illustrated. In particular, the RF envelope signal of the data-0 and data-1 coding symbols used for data coding is illustrated. Tar? is the reference time interval for interrogator to tag signaling (i.e., signaling by the radio frequency identification (RFID) reader subsystem to the transponder) and represents a duration of the data symbol 0 representing, for example, binary 0. The value x (within the scale of values from 0.5 to 1.0) defines the duration data-1 based on the reference time interval Tar ?, that is, the value x defines a relative time interval of reference for the signaling of interrogator to label and represents a duration of the symbol data-1 based on the duration of the symbol data-0, where the symbol data-1 represents for example binary 0. The high values represent a transmitted continuous wave (CW), which is designated on the excitation interrogation or RF signal as well. Low values represent attenuated CW. The depth of modulation, time of origin, time of calda and width of pulse are defined. The valid values of the aforementioned parameters depend on the type of modulation used for transponder communication including Double Sideband Amplitude Displacement Handling (DBS-ASK), Individual Sideband Amplitude Displacement Handling (SSB-ASK) and Manipulation by Displacement of Amplitude of Reversion of Phases (PBS-ASK), which have to be supported by the transponders. According to the type of modulation the reference time interval Tar? it can have the values 6.25 μs (for DSB-ASK), 12.5 μs (for SSB-ASK) and 25 μs (for PR-ASK). Furthermore, the depth of modulation should be at least 80%, typically 90% and maximum 10%. The time of origin of the RF envelope (10%? 90%) and the time of origin of the RF envelope (90%? 10%) must be within the range of 0 to 0.33 * Tar? . The RF pulse width must be within the MAX scale (0.265 * Tar ?, 2) to 0.525 * Tar ?. The RF pulse width, RF envelope time, RF envelope drop time are specific to the radio frequency identification (RFID) reader subsystem. These parameters can only be read and are not modifiable. The carrier sequence can be selected from the frequency scale of 860 MHz to 960 MHz. However, local regulations must be considered and the carrier frequency must also be determined by the local radio frequency environment. With reference to figure 6d, a synchronization of the reading link to the transponder (R- »T) and the transponder to the reader (T- >) is illustrated.; R). The Transponder-to-Transponder (R-> T) communication is based on the continuous wave (CW), which corresponds to the RF interrogation / excitation signal mentioned above. The continuous wave is continuously emitted by the radio frequency identification (RFID) reader subsystem to ensure the energization of the radio frequency identification transponder (RFID). To access the information stored by the radio frequency identification transponder (RFID), the set of commands is provided, which can be modulated on the continuous wave. In more detail, the radio frequency identification (RFID) reader subsystem is activated by sending information to one or more radio frequency identification (RFID) transponders by modulating an RF carrier (continuous wave (CW), interrogation or excitation RF signal) using Double Sideband Amplitude Shift (DSB-ASK), Single Sideband Amplitude Shift (SSB-ASK) or Phase Reversal Amplitude Shift (PR-ASK) using a Pulse Interval Coding Format (PIE) . The radio frequency identification (RFID) transponders are arranged to receive their operational energy from this same modulated RF carrier. A radio frequency identification (RFID) reader subsystem is further arranged to receive information from a radio frequency identification (RFID) transponder when transmitting an unmodulated RF carrier (continuous wave (CW), interrogation or excitation RF signal) and listening to a previous answer. The radio frequency identification (RFID) transponder communicates information by backscattering the amplitude and / or phase of the RF carrier. The coding format, selected in response to commands from the Radio Frequency Identification Reader (RFID) subsystem, is for example either a subcarrier modulated by FMO or Miller. The communication link between a radio frequency identification (RFID) reader subsystem and the radio frequency identification (RFID) transponder is half duplex, meaning that the radio frequency identification (RFID) transponder should not be required to demodulate commands from the identification reader subsystem by radiofrequency (RFID) while this is taking place. A radio frequency identification (RFID) transponder must not respond using full duplex communications. In an exemplary manner, a command to select, consult and recognize is illustrated. Before issuing a command to the radio frequency identification transponder (RFID), the radio frequency identification (RFID) reader must at least emit the continuous wave for eight times of the symbol and the RTcai period of the release symbol Interrogator to Label, where RTca? is equal to the length of the symbol data-0 and data-1 (that is, RTcai is within the time scale of 2.5 * Tari to 3.0 * Tari). After receiving a select command by a radio frequency identification (RFID) transponder, the transponder is instructed to answer that command. The first query command instructs the selected radio-frequency identification transponder (RFID) to respond to a random number of 16 bits or a pseudorandom number (RN16). Upon receipt of a recognition command from the radio frequency identification (RFID) reader that informs the radio frequency identification (RFID) transponder that the 16-bit random or pseudo-random number (RN16) is valid, the transponder transmits for example a electronic product code (EPC), protocol control (PC) and a cyclic redundancy check (CRC) value. The radio frequency identification (RFID) reader is able to verify, based on the cyclic redundancy review, whether the response was successfully received or not. Consequently, the radio frequency identification (RFID) reader can then transmit an additional command or a non-recognition command. The last command is transmitted to indicate to the radio frequency identification transponder (RFID) that the payload of the previous response has been received erroneously. As indicated in figure 6d, several waiting periods have to be considered for example waiting periods between transmissions of consecutive radio frequency identification (RFID) reader commands (T4), between the end of a radio frequency identification (RFID) reader command and the start of the transponder response of radio frequency identification (RFID) (Ti), and vice versa, between the end of the response of the radio frequency identification transponder (RFID) and the start of the radio frequency identification (RFID) reader command (T2) . Commands and scripts are provided to remove information from radio frequency identification (RFID) transponders and / or to modify the information stored in radio frequency identification (RFID) transponders. With reference to Figure 6e, major radiofrequency identification (RFID) scripts and radio frequency identification (RFID) transponder states are illustrated illustratively. Radio frequency identification (RFID) communication in accordance with the EPCglobal standard is arranged for communication with a population of transponders, which includes, in particular, communication with a single transponder. The radio frequency identification (RFID) reader subsystem is activated to handle a population in radio frequency identification (RFID) transponders based on the three basic processes, which in turn comprises one or more specific process commands. The following description briefly details the basic processes without going into details. A Select process is provided to choose a population of radio frequency identification (RFID) transponders for subsequent communication, in particular communication of inventory commands and access. A Select command can be applied selectively to select a particular population of radio frequency identification (RFID) transponders based on criteria specified by the user. This operation can be seen as analogous when selecting one or more records from a database. An Inventory process is provided to identify radio frequency identification (RFID) transponders, that is, to identify radio frequency identification (RFID) transponders of the population selected by the Select command means. A radio frequency identification (RFID) reader subsystem can begin an inventory round, that is, one or more transponder response cycles and inventory commands, by transmitting a Query command in one of four sessions. One or more radio frequency identification (RFID) transponders can answer. The radio frequency identification (RFID) reader subsystem is activated by detecting a single response of radio frequency identification transponders (RFID) and requesting the PC, EPC and CRC of the radio frequency identification transponder (RFID). The inventory process can comprise several inventory commands. An inventory round operates in one session at a time. An Access process is provided to communicate with the radio frequency identification (RFID) transponder, wherein the communication comprises reading especially from and / or writing to the radio frequency identification (RFID) transponder. Individual radio-frequency identification (RFID) transponders must be uniquely identified before the Access process. The Access process may comprise several access commands, some of which employ cover coding based on a time of the communication link from Reader to Transponder. In more detail, the Selection process uses a single command, Select, which can apply a radio frequency identification (RFID) reader subsystem successively to select a particular population of radio frequency identification (RFID) transponders based on user-defined criteria., making possible the division of the transponder based on union, intersection and negation. The Radio Frequency Identification (RFID) reader subsystems are activated by performing union and intersection operations when issuing successive Select commands. The inventory process command includes Query (query), QueryAdjust (query setting), QueryRep, ACK (recognition), and NAK (non-recognition) commands. The Query command initiates an inventory round and decides which radio frequency identification (RFID) transponders participate in the inventory round, where "inventory round" is defined as the period between successive Query commands. The Query command includes a segment count parameter (used for random withdrawal in the scheme to avoid collisions). The Q segment counting parameter can be configured and set by the radio frequency identification (RFID) reader subsystem. After receiving a Query command, each of the participating radio-frequency identification (RFID) transponders must select a random value on the scale from 0 to 2Q-1 and must store this value in their segment counter. Radio frequency identification (RFID) transponders that collect a zero must change to the response state and respond immediately. Radio frequency identification (RFID) transponders that collect a non-zero value must change to the arbitrary state and wait for a QueryAdjust command or a QueryRep command. Assuming a single radio frequency identification (RFID) transponder answers, the query-response algorithm provides the radio frequency identification (RFID) transponder for the backscatter of a 16-bit random number or a pseudorandom number response (RN16) to the enter the answer. The radio frequency identification (RFID) reader subsystem recognizes the radio frequency identification transponder with an acknowledgment command (ACK) that includes the same RN16. Then, the recognized radio frequency identification (RFID) transponder changes to the recognized state, re-scattering its PC, EPC and CRC. In addition, the radio frequency identification (RFID) reader subsystem can issue a QueryAdjust or QueryRep command, causing the identified radio frequency identification (RFID) transponder to change to the ready state, and potentially causing another radio frequency identification (RFID) transponder. initiate a query-response dialog with the reader subsystem of radio frequency identification (RFID), starting again the sequence of consultation processes mentioned above. If a radio frequency identification (RFID) transponder can not receive the ACK command or receives the ACK command with an erroneous RN16, the radio frequency identification (RFID) transponder must return to the arbitrary state.

Radio frequency identification (RFID) transponders in arbitrary states or response states then receive a first QueryAdjust Q setting (increasing, reducing or leaving it unchanged after selecting a random value on the scale from 0 to 2Q-1 and storing that value). In its segment counter, Radio Frequency Identification (RFID) transponders that collect zero must change to the response state and respond immediately.The radio frequency identification (RFID) transponder that collects a non-zero value must change the arbitrary status and wait a QueryAdjust or QueryRep command: Radio frequency identification (RFID) transponders in the arbitrary state reduce their segment counter each time they receive a QueryRep, changing to the response state and backscattering an RN16 when its segment counter reaches zero. , during the RF activity cycle of the radio identification reader subsystem frequency (RFID), first the radio frequency identification (RFID) transponders selected according to the Select process, later the radio frequency identification (RFID) reader subsystem can proceed to the inventory process and finally an access process can be executed. Those skilled in the art will appreciate that the scheduler is preferably activated to obtain one or more of the parameter values mentioned above and, if desired or required, to modify one or more of the parameter values. The programmer obtains and / or modifies the parameter values through the configuration and adjustment interface described above. The programmer can at least obtain and modify parameter values that are relevant to align the RF activity of the radiofrequency identification reader subsystem (RFID) and the cellular communication subsystem. The activity of the cellular communication subsystem is prioritized over the activity of the radio frequency identification (RFID) reader subsystem due to the fact that the activity of the cellular communication subsystem is typically under the control of the Radio Access Network (RAN) and the Possibilities for the terminal to affect the activity of the cellular communication subsystem are very limited. Correspondingly, the time periods available and their synchronized distance allowed by radio frequency identification (RFID) communication are known from the periods of activity and non-activity of the cellular communication subsystem. This means that the maximum durations of individual continuous waves (CWs), refer to Figure 6d, and a duration of sleep between two consecutive continuous waves (CWs) is known. Within these maximum durations, the radio frequency identification (RFID) communication between the reader subsystem and the transponders has to be carried out, referring to figures 6d and 6e. The length of time required for a contemplated radio frequency identification (RFID) communication procedure comprising one or more commands and responses can be determined or calculated from a sequence of commands and responses as well as from the synchronization requirements illustrated above. By adjusting one or more synchronization parameters including in particular Tari reference time interval, relative reference time interval value x, RF pulse width carrier frequency and Q segment count parameters, the duration in time required for The radio frequency identification (RFID) communication procedure contemplated can be optimized to thereby establish a maximum duration of a single continuous wave (CW). The adjustment of the parameter must be at least possible within one or more tolerance scales. After adjusting the digital activation signal (I / O), which substantially represents a Boolean parameter, the Select process is started. further, the RF power level of the radio frequency identification (RFID) reader subsystem can be adjusted in a corresponding power adjustment command by the programmer to the radio frequency identification (RFID) reader subsystem. Furthermore, the number of radio frequency identification (RFID) transponders that will be read can be defined or limited. It should be noted that the periods of non-activity of the cellular communication subsystem may be short in time in relation to the duration in time required for a radiofrequency identification (RFID) communication in the manner described above based on the EPCglobal standard for reasons of illustration. The bit rate from Reader to Transponder is within a scale of 26.7 kbps to 128 kbps depending on the modulation scheme applied, while the bit rate of transponder to reader within a scale of 40 kbps to 640 kbps (and 5 kbps at 320 kbps when modulating a subcarrier). However, the effective bit rate suffers from several synchronization requirements illustrated for example above with reference to FIG. 6d. The period of non-activity available for radio frequency identification (RFID) communication should be used as effectively as possible. The communication and operation of radio frequency identification (RFID) is mainly described above in view of the application of labeling and identification of products. It should be understood that the invention is not limited to any specific application and the use case in the field of radio frequency identification (RFID) technology. In general, radio frequency identification (RFID) technology can be considered as a wireless storage technology, where transponders provide random access or read-only storage, which is wirelessly accessible by means of reader subsystems. In principle, the communication between transponders and reader subsystem operates in analogy to the illustrative modalities. For example, radio frequency identification (RFID) technology has been selected to store biometric identification information in digitally enhanced passports. This passport comprises a radiofrequency identification transponder, which stores biometric information about the passport holder such as a digital image of his face, a digital representation of one or more fingerprints and / or a digital representation of an iris scan. Radio-frequency identification (RFID) reader subsystems provided at passport control stations at a state boundary make it possible to access stored biometric information to authenticate the passport bearer. In particular, transponders of radio frequency identification (RFID) in passports implement access control mechanisms to prevent unauthorized access to stored information.

In addition, the radio frequency identification transponder (RFID) can also be provided with a logic sensor, especially condition monitoring sensors or environmental monitoring sensors such as temperature sensors, humidity sensors, pressure sensors, gas sensors (which detect one or more specific types of gas) and the like. The calibration of these sensors and / or the access to reading them can be operated through the interfaces described above in detail. However, should it be considered that the calibration access to a sensor implemented in a radio frequency identification (RFID) transponder requires a period of time, which will be designated as a Treac sensor reading period? - The same applies to access of reading the data generated by this sensor. Access to data generated by a sensor or obtained from a sensor requires a period of time, which will be designated as a Twnte sensor write period. • Note that one or more Twpte sensor write periods and one or more periods of reading Treac sensor? they should also be considered when adjusting and / or optimizing the operation of the Radio Frequency Identification Reader (RFID) subsystem. Optimization can be obtained by limiting the number of accesses to sensor reading and / or sensor writing, preferably only to one or more specific sensors by communication with the radio frequency identification (RFID) transponder during a period of non-activity. In contrast to the parameters mentioned above that refer to communication properties (parameters related to communication) the sensor-related parameters can be designated in general as application-related parameters. According to yet another embodiment of the present invention, the operation of the radiofrequency identification (RFID) reader subsystem can be used to emit an RF interrogation signal (RF excitation signal, continuous wave) and, if necessary and / or requires, for Listen Before Speaking measurements. The RF interrogation signal is for example (continuously) emitted to energize one or more radio frequency identification (RFID) transponders in the coverage area of the radio frequency identification (RFID) reader subsystem (RFID). The communication of data with the one or more radio frequency identification (RFID) transponders (including reception of data from radio frequency identification transponders (RFID) as well as the transmission of data and / or commands to radio frequency identification transponders ( RFID)) can be operated on a different radiofrequency band, possibly also with a different protocol and / or based on a different wireless data communication technology. However, the power supply through an RF interrogation signal is adequate to make possible the provision of a passive energy module capable of wireless data communication. Those skilled in the art will appreciate that the concept of the present invention described based on a cellular communication subsystem is also applicable to other radiofrequency communication subsystems, in particular wireless network interface subsystems. This means that the activity programming of a radio frequency identification (RFID) reader subsystem according to one embodiment of the present invention should not be limited to the cellular communication subsystems mentioned above, but that the general solution is also applicable with the Standards of Mobile Telephony of 3rd Generation and 4th Generation contemplated, WLAN (Wireless Local Area Network), WiMAX, UWB (Ultra Wide Band), Bluetooth and any other wireless technology. However, the interference would be worse for a wireless communication subsystem operating near the 900 MHz UHF band of the UHF radio frequency identification (RFID) subsystem, the broadband noise originating from the radio frequency identification reader subsystem. (RFID) could also cause difficulties in the wireless communication subsystem operating at other frequencies of the spectrum.

Moreover, programming according to one embodiment of the present invention could be very beneficial with 2.4 GHz ISM radio frequency identification (RFID) reader subsystems, which could cause powerful interference in wireless communication subsystems operating in the band. of ISM frequencies of 2.4 GHz, for example, IEEE 802.11b / g WLAN and Bluetooth. Based on the inventive concept illustrated in accordance with the above description, those skilled in the art will understand that a substantially concurrent operation of a radio frequency identification (RFID) reader subsystem and a cellular / wireless communication subsystem is operable. The advantages of the substantially concurrent operation of both subsystems can be taken by the user when additional data communication is desired by the user for example to retrieve additional information depending on the information withdrawn from a radio frequency identification transponder.

(RFID) such as a data withdrawal in a database that stores this additional information. In view of the radio frequency identification (RFID) transponder conforming to EPCglobal which conventionally provides a unique electronic product code (EPC) worldwide, which serves as a tagged product identification code, the additional information may comprise for example information related to supply chains such as origin, manufacturer, vendor, date of manufacture, expiration, etc. Another use case may comprise transmitting the information read from the radio frequency identification transponder (RFID) in a database to supply and for supply chain management purposes. In contrast to the conventional way of first removing information from the radio frequency identification (RFID) transponder, intermediate storage of the withdrawn information and after that carrying out the removal of the database by means of the cellular / wireless communication interface that it makes possible the access by wide area network (WAN) to for example an Internet database service, the concept of the invention allows to skip the intermediate storage and accelerates the recovery of a database thanks to a substantially operation concurrent of both subsystems. Especially in the use case, where a multiplicity of radio frequency identification (RFID) transponders are read and the information read can be stored in a database or the information can be removed from a database according to the information read, the advantages of the inventive concept are immediately apparent. In addition, the concept of the invention solves the operation of the radiofrequency identification (RFID) reader subsystem. Due to the time-aligned operation of the subsystems, when the cellular / wireless communication subsystem is typically prioritized due to implementations and side network requirements, radio frequency identification (RFID) communication has to be adjusted to adapt to the available periods of non-activity of the cellular / wireless communication subsystem. This adaptation requirement can be achieved by adjusting one or more parameters obtainable from the radiofrequency identification (RFID) reader subsystem and adjustable to make possible the coincidence in time of the radio frequency identification (RFID) communication with the one or more periods of non-compliance. activity available. It will be obvious to those skilled in the art that as technology advances, the inventive concept can be implemented in a large number of ways. The invention and its embodiments are then not limited to the examples described above but may vary within the scope of the claims. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
