In spite of the same message, i.e., the same information can be used in various waveforms. For example, a message relating to the same subject, can be transmitted: (1) in the form of images; (2) as the spoken word; (3) how the written word; (4) as an encrypted word or image.

Mode mdcr-BP/TLD Universal mobile telecommunications system (UMTS) interface radio communication system in forward and backward directions (see TSG RAN WG1 (S1.21): "3rdGeneration Partnership Project (3GPP)", Vers.0.0.1, 1999-01) again based on a three-tiered structure, consisting of superquadra SC, frame radio CU and selected time intervals VI for all physical channels, as shown in Fig.3. The corresponding supercar SC again contains, for example, 72 frame radio CU, while each frame of the radio CU again contains, for example, 16 time intervals VI...VI.

In Fig. 4 shows in accordance with the scenario of radio communication according to the GSM standard two cell radio and placed them in the base station (base transceiver station - BPS), and the first base station BPS (transceiver) omnidirectional irradiates a first cell radio AR, and the second base station BPS (transceiver) omnidirectional irradiates the second cell radio EAR, and, on the basis of Fig.1 and 2, the script radio with repeated use of the channel in accordance with the frequency/temporal/ code division multiplexing, in which the base station BPS, BPS via a radio interface corresponding to the considered scenario, radio, communicate or have the ability to communicate with many located in the cell radio AR, AR mobile stations MS.. .MS (transmitting device) corresponding to the transmission channels KP. The base station BPS, BPS connected in a known manner (as in the communication system GSM) base station controller (ASC), which is under the control of the base stations performs the distribution function of frequency and switching. The base station controller KBS with his hand through the switching center CSM mobile stations associated with the higher-level communication network, e.g. the public switched telephone network (PSTN). The switching center mobile stations SMC is the control center for the shown communication system. He assumes full control of the call and performs using the attached registers (not shown) authentication of subscribers participating in the implementation of the communication and control locations on the network.

In Fig. 5 shows a functional block diagram of a base station BPS, BPS made in the form of a transceiver device, and Fig.6 shows a functional block diagram of the mobile station MS...MS, made in the form of radio devices. The base station BPS, BPS is sending radio messages to mobile stations MS...MS and receive messages from them, while the mobile station MS...MS transmits soeno Plant and the receiving antenna Print, and the mobile station MS 1...MS has a common antenna Ant used with the antenna switch up as on transmission and on reception. In the return line connection (receive channel) base station BPS, BPS receives through the receiving antenna Print at least one message with a single frequency/temporal/code component from at least one of the mobile stations MS. ..MS, while the mobile station MS...MS in a straight line (receive channel) through a common antenna receives, for example, at least one communication connection with one frequency/temporal/code component from at least one base station BPS, BPS. Message Radiocommunication CF formed when the carrier signal, the advanced along the spectrum, with a superimposed information by modulation of the data symbols.

In the receiving unit PRU received carrier signal is filtered and converted to an intermediate frequency, which is then sampled and quantized. After analog-to-digital conversion of the signal distorted in the channel due to multipath propagation, served in the correction block Bq, which corrects most part distortion (with synchronization).

Then in channel estimation block (message sending radio WED. The transmission properties of the channel that you specify in the time domain using an impulse response of the channel. In order to estimate the impulse response of the channel, the radio message on the transmission side (in this case from the mobile station MS...MS or respectively the base station BPS, BPS) is given special additional information generated in the form of test information sequences, the so-called midanbury (analogiei with the "preamble").

In the detector data DD, common to all received signals, signal components contained in the common signal, which is specific to the mobile station, adjusted and stand out in a known manner. After the correction, and selection inverter symbol in PDS data received data symbols are converted into binary data. After that, in the demodulator of DMT from the intermediate frequency to obtain the initial stream of data bits before the demultiplexer Dmult separate time intervals are associated with the correct logical channels and thereby different mobile stations.

In channel codec (QC) of the received bit sequence is decoded componentwise. According to channel the key signal in the case of the base station (Fig.5) data management and signaling and voice data for transmission to the base station controller KBS transferred to the appropriate interface (S), used for signaling and encoding/decoding of speech (speech codec), and in the case of the mobile station (Fig. 6) data management and signaling are transmitted to the control unit and alarm (BEADS) used to perform all functions of the alarm and control mobile station and the speech data to the speech codec (CU) made with the possibility of input and output speech signal.

In the speech codec interface, And base stations BPS, BPS speech data is converted into a predetermined data stream (for example, a stream with a speed of 64 kbit/s in the direction to the network and, accordingly, the flow at the rate of 13 kbit/s from the network).

In the control unit BU is full control of base stations BPS 1, BPS.

In the forward direction (transmission path) base station BPS, BPS passes through the transmitting antenna Plant, for example, at least one communication radio WED containing frequency/time/code component, at least one mobile station MS...MS, while in the opposite direction (transmission path) of the mobile station MS...MS through the common antenna Ant transmits, for example, at least one communication radio with CF frequency/temporal/code components, The PO2 in Fig.5 the fact that the received codec channel QC from the base station controller ASC interface And data management and signaling and voice data are sent in the time interval of the control and alarm or time interval of the speech signal, and the data in these time intervals componentwise encoded by receiving the bit sequence.

The transmission path begins at the mobile station MS...MS in Fig.6 the fact that the received codec channel QC from the speech codec KR speech data and from the control unit and alarm BUS control data and signaling are sent in the time interval of the control and alarm or time interval of the speech signal, and the data in these time intervals componentwise encoded by receiving the bit sequence.

Received in the base station BPS, BPS and the mobile station MS...MS bit sequence is converted into the character data corresponding to the data Converter in the characters (PDS). Then the received data symbols are expanding the spectrum using a code unique to each user, in block spread spectrum (SRS). In the generator package SE, consisting of a block layout packages (Brestova information sequence in the form of "midanbury" for channel estimation, and in multiplexer M thus obtained information packet is placed in the corresponding time interval. Then the received packet is modulated in the modulator Mod to transfer at a high frequency, and is subjected to digital-to-analog conversion before thus obtained signal in the form of radio messages CF via the radio device RPD will be transferred to the transmitting antenna Plant or respectively in the joint antenna Ant for radiation.

Communication systems operating in the duplex transmission with a temporary seal (TLDs) are communication systems in which a frame transmission, which consists of several time slots, divided into two parts, respectively, for direct communication line and a return line, preferably in the middle.

Communication system with TLD, which has a similar frame transmission is, for example, a known communication system DECT (DECT - Digital enhanced (formerly European) cordless communication system; see Nachrichtentechnik Elektronik 42 (1992) Jan./Feb. 1, Berlin, DE; U. Pilger "Struktur des DECT-Standards", 's. 23-29, in conjunction with the ETSI - publication ETS 300175-1. . .9,0 kt. 1992; and DECT-publication DECT-Forum, Feb.1997, S. 1-16).

In Fig. 7 shows the frame transmission standard, the second communication line. For any bilateral connection radio on a predefined frequency in the direction of a straight line (PL) and in the reverse direction of the connection line (OL), according to the DECT standard, it selects a free pair of time intervals containing one time interval of a straight line (VIPLand one time interval of the reverse line (VIOL); the interval between the time interval of a straight line VIPLand time interval of the reverse line VIOLalso according to the DECT standard, is half the duration (5 MS) frame transmission of the DECT standard.

Communication systems operating in the duplex transmission with frequency-seal (DCU), represent a communication system in which a frame transmission, consisting of several time intervals for direct communication line is transmitted in the first frequency band, and for the return line is transmitted in the second frequency band.

Communication system with DCU, which has a similar frame transmission is, for example, a known communication system GSM (GSM - global system for mobile communication; see, for example, Informatik Spektrum 14 (1991) June, Nr.3, Berlin, DE; A. Mann: "Der GSM-standard - Grundlage für digitale europaeische Mobilfunknetze", S. 137-152; in conjunction with pleshet many logical channels, which are defined as services of the transmission channel, for example channel access (channel ID), a channel broadcast (channel current), fast associated control channel (channel SSA), the channel search call (channel RO) channel random access channel (SD) and channel traffic channel (Tr), the corresponding functions are described in several publications (see, for example, Informatik Spektrum 14 (1991) June, Nr.3, Berlin, DE; A. Mann: "Der GSM-standard - Grundlage für digitale europaeische Mobilfunknetze", S. 137-152; telekom praxis 4/1993, P. Smolka: "GSM-Funkschnittstelle - Elemente und functions, S. 17, 24). The system of the GSM standard has to the same frame structure, in which each supercade with a duration of 60 MS 13-th time interval superquadra made in the form of "idle" frame. In this "idle" frame, which is not transmitted useful data, mobile station of the GSM system is able to transfer various messages, especially messages for pre-synchronization for a possible treatment for switching communication channels.

The biggest difference between the GSM system uses a frequency-time plane, functioning in a coordinated licensed mode, and the DECT system, also using the frequency-time plane and functioning in a disorderly relicensing system or subscriber of the communication system.

In a coordinated licensed communication system distribution channels controlled from a Central location from network provider. This is possible because all mobile stations within the service area of the base station use the same time base, i.e., can operate synchronously. Synchronous operation allows the exact determination of the boundaries of time intervals and thereby to clearly differentiate between various subscribers of the communication system. There is no need to synchronize the operation of neighboring stations, as the diversity of channels used in neighboring cells, the radio, in the General case is based on the planning of the use of frequencies in the frequency plane. This type of distribution channels is designated as "fixed distribution channel (PRK).

In uncoordinated unlicensed communication system, in which there is no such Central point for distribution of frequencies, the first channels are selected on a dynamic basis, which is referred to as "dynamic selection of channel (DSC), and then distributed. The frequency-time plane serves as a platform or "pool" as for the dynamic selection of channels, and for RASU region and selects the result of the combination of frequency and time interval, when the transmission channel is less affected by the interference. Due to the fact that neighboring necoordinirovannami working base stations and mobile devices are always asynchronous and therefore temporary bases mutual way pass through each other and respectively drifting relative to each other, it is often the case when the degree of interference reaches an unacceptably high level. In this case, should be moving connection connection ("transfer call") on the other channel, i.e., must be entered or initiated a new combination of frequency and time interval. In this case we speak of transfer (move) communication within the cell.

As in scenario system UMTS (third generation mobile communication systems or system IMT-2000) mode SMDR/DCU and mode mdcr-BP/TLDs can be used together, requires efficient processing of logical channels and, accordingly, the service transmission channel in the interface radio communication system for communication with the wireless transmission based on the principles of the code and the temporary seal between the mobile and/or stationary transceiver devices.

The task underlying the invention is that for a communication system with wireless the local transmitting-receiving device in the procedure of communication to offer a way which allows for a reliable way to make the indication of communication for different modes of operation of transceiver devices.

This problem is solved by the characteristics specified in paragraph 1 of the claims.

The idea underlying the invention is that according to paragraph 1 of the claims in the communication system to the wireless transmission based on the principles of the code and the temporary seal between the mobile and/or stationary transceiver device as in mode TLD and mode DCU stationary transmitting-receiving device is in "idle" (i.e. Unallocated free) frame temporary seal superquadra disables the alarm broadcast, in the current pair of time intervals due evaluates interfering situation by determining the jamming power, compares the measured interference value with a predefined threshold value, and if the value of the interference is greater than or equal to the threshold value, then enters the interference value in the list, select the channel for the transmission of communications and/or indicates the status of the transmission link for the transmission of communications.

Preferred further embodiments of described in the dependent punktorah shows the following:

VI'8, with the first four time intervals VI'1. . . VI'4 are provided for direct communication line PL, and the second four time intervals VI'5...VI'8 is provided for backward communication line OL. The number of time intervals equal to 16 according to Fig.1 and 3 and reduced to 8 only for purposes of illustration, table of distribution channels, shown in Fig. 9, and does not impose any limitations on the invention. On the contrary, the number of time intervals may, like other physical resources (e.g., code, frequency, etc.,) to vary con is s for channels with components of the frequency/code/temporary seal on the base frame of the temporary seal according to Fig.8. Component temporary seal this table covers the time intervals VI...VI'8 time division mode TLD according to Fig. 8. Component frequency sealing covers 12 frequency B1...

At first the frequency of B1 in the code plane occupied codes K1...K8 implemented sealing implemented in the form of a service transmission channel, for example, a logical channel communication system, such as a control channel for signalling, channel access (channel ID), a channel broadcast (channel current), the channel search call (channel RO) channel random access channel (DM), the channel traffic channel (Tr) and/or fast associated control channel (channel SSA), required in the communication system in the direction of a straight line and/or reverse link. This seal is suitable for the above-mentioned communication system, because thereby it is possible to avoid excessive employment of time intervals, i.e., loading a temporary resource.

In Fig.9 shows the preferred form of execution, according to which the first frequency of the B1 in the direction of a straight line in the first time interval of the return line in the fifth time interval TS'5 as specified (agreed) of the second selected time interval are preferably used all the codes K1...K8 to seal these transmission channel. Of course, it is also possible to use a smaller number of codes or more of their number, if available provided more than eight codes.

With this seal, as shown in Fig.9, codes K1...K8 in the first time interval TS'1 distributed so that one code is reserved or allocated for the control channel for signalling and channel OD, another code - channel noise reduction and channel PV, and the remaining six codes for channel Tr, while codes K1...K8 in the fifth time interval TS'5 are distributed in such a way that one code is reserved or dedicated for channel DM, another code for channel SSA for indicating the status of communication (i.e., move the call)and the remaining six codes again for channel Tr.

In Fig. 10 is a diagram of the message flow of procedure of the "passing communication". Procedure "passing communication" consists in principle of three stages: the first stage, which is indicated as an indication of the transmission link, the second stage, kosorylaya transmission connection, moreover, these steps are performed in sequence.

In case of deterioration of the quality of the transmitted service (QoS) base station indicates the status of the transmission link", i.e. the procedure is started "passing communication". The deterioration in the quality of the transmitted service (QoS) can be installed as an option by the mobile device, such as a first mobile device A, the second mobile device A, n-th mobile device of the MUP, which informs the deterioration of the base station, for example, channel SSA. In this case, the base station BS according to the process of "passing communication" is the leading and the mobile device A...MP is a slave. It is also possible that the mobile device is in the process of "communication" is the leading and the base station to the guest.

By specifying the "passing communication" base station BS selects the last in the list of selectable channels a couple of time intervals "communication", for which the quality of the transmitted services better than for the current pair of time intervals of communication. At the first stage of the process of "communication", i.e. at the stage indicating the communication pair of time intervals for transmitting swasa station BS for this disables the alarm in channel broadcast (GSR), specifies the GSM idle (i.e., free, unoccupied) frame interfering situation by determining the jamming power, for example, by measuring the field strength of the signal in the time interval of communication and stores the measured result (the value of interference) in the select list of channels. In order not constantly on the basis of inclusion in the select list of channels was conducted by the procedure of transfer of communication (hysteresis effect), is determined threshold value, which is between the respective current value received interference and some interference value, which corresponds to the "most peaceful" couple time intervals. Base station BS should not be taken to include in the select list of channels and/or to specify a condition and to initiate the procedure of "communication", if the value received interference does not exceed a predefined threshold value.

The second phase of the procedure "passing communication", namely the initiation of communication begins with the fact that the base station BS sets the channel current in a time interval of a straight line connection of the pair of time intervals of communication. In this time interval a direct line of communication pairs temporary Internet who will be in the time interval of the straight line of the pair of time intervals due.

In the broadcast mode transmission, which similarly initiated the second stage of the procedure "passing communication", in contrast to the mode of traffic, not only is the simultaneous transmission of information (data services).

After successfully establishing a channel current in a time interval of a straight line connection of the pair of time intervals of the communication base station BS transmits the first message S1 "transmission Request of communication" channel current in a time interval of a straight line connection of the pair of time intervals due to mobile devices A...MP associated with the base station BS on this channel. With this first message S1 mobile devices A...MP reported position of the pair of time intervals "communication". After transmission of the first message S1 base station BS continues simultaneous transmission of information (data services) in time intervals of the straight line of the pair of time intervals "communication" and passes to the same first message S1 channel noise reduction in the time intervals of the straight line of the pair of time intervals due to until all associated with the base station BS of the mobile device MO...MP confirm the initiation of the "transfer whodat, if the corresponding mobile device MO...MP are still required to transmit data after receiving the first message S1 directly with pairs of time intervals due to a couple of time intervals "communication". In this case, transmission data in a pair of time intervals communication is terminated without breach of continuity continues in a pair of time intervals "transmission connection".

If the corresponding mobile device MO...MP still have data to send, the mobile device MO...MP transmits the second message S2 "confirmation of communication" channel signaling to the base station BS.

The base station BS receives thus, on the one hand, data in pairs of time intervals of communication and in a pair of time intervals "communication" and, on the other hand, the second message S2. The initiation of communication by the first message S1 base station is considered as confirmed if the first-mentioned case, the data transmitted from the corresponding mobile device MO...MP in the time interval of the reverse line pairs of time intervals "communication", accepted by the base station BS without errors or if Adachi communication", i.e., the initiation of communication" is completed, if all mobile devices A...MP confirmed the initiation of communication by the first communication C1.

At the third stage of the procedure "passing communication", i.e., at run time "transmission connection", after all mobile devices A...MP confirmed the initiation of communication by the first message S1, a pair of time intervals "communication" is used thus as a new pair of time intervals of communication, and finally, the transmission used is still a couple of time intervals the connection is terminated.
