Integrated local communication system

The present invention relates to a method and system for establishing a communication line in a wireless local communication system. The present invention belongs to the field of solutions which are described in detail in the following documents: US Patent Application Serial Number 08/476 504, entitled "MODULAR UNITHEADSET", registered on June 7, 1995 (case number 27946-00098; inventors: Nils Rutger Rydbeck and Per Stern) ; US patent application, serial number 08/471 606, entitled "ELECTRONIC EQUIPMENTAUDIO SYSTEM, registered on June 6, 1995 (case number 27946-00085); U.S. Patent Application, Serial Number 08/577 086, entitled "IDENTIFICATION OF MOBILE CALLS WITHIN A MOBILE TELEPHONE SYSTEM, registered on December 22, 1995 (case number 27943-00033; inventor: Eric Valentine); US Patent Application Serial Number 08/353 966, entitled "MODULAR RADIO COMMUNICATIONS SYSTEM, registered December 12, 1994 (case number 27946-00070; inventor: Per Stein).

The recent period has brought many solutions in the field of wireless telecommunications, which in turn has allowed to obtain a number of new products and provide new services. In the field of mobile telephony, new services include both private, available to subscribers of a private network in the home and office, as well as public, available to subscribers thanks to the public cellular network. Both private and public services can be based on a mobile phone network, and thanks to the so-called "roaming" subscribers can use the services of various private and public system stations.

Private cellular telephony services are usually provided by a private cellular telephony network having its own wireless telephony system standard, for example CT-2 (Cordless Telephone Standard 2). Private telephone systems can be an independent network or connected to another telephone network.

In contrast, public mobile telephony services are provided in a mobile telephony network using one of the commonly used standards, such as AMPS (Advanced Mobile Phone Service), System Standard, PCS (Personal Communications System) or GSM (Global System for Mobile Communication Standard).

New solutions have also appeared in the field of wireless telephony products. For some time now, wireless telephony communication systems connected to the so-called public switched telephone network PSTN (public switching telephone system) have been known. Wireless telephones use a portable telephone unit that connects to the base station by using a pair of radio transceivers in the portable unit and base station. The conversation occurs by sending a dial tone and voice signals from the transmitter in the portable unit to the receiver in the base station, and then in the traditional way via the PSTN line. Similarly, when answering the phone, voice signals are sent from the transmitter in the base station to the receiver in the portable unit.

Although the use of cordless telephones is convenient due to the lack of a cable preventing free movement, they, like traditional corded telephones, require holding a portable unit in your hand. Recent attempts to remove restrictions that can be encountered when operating traditional cordless phones have resulted in the creation of a set of words ^^^^ owk ^^,wego who does not interfere with other activities with both hands. As described in US Patent No. 4,882,745, granted to Silver, "a wireless telephone headset includes only one hand-covering telephone while the other remains uncovered. Another device is disclosed in U.S. Patent 4,741,030 (inventor: Wilson), in which the wireless headset is provided with the necessary keys near the microphone so that they are visible to the user. As with the Silver solution, the Wilson solution does not use two headphones and a volume control that would improve the sound quality by preventing outside noise. Another wireless headset that uses only one handset is described in US Patent 4 484 029, owned by Kennedy.

A competitive solution for the above-mentioned wireless headsets is disclosed in U.S. Patent 5,113,428, where the portable unit is placed in a headset equipped with its own key system, control buttons, battery, transceiver and two headphones with volume control.

The patent application, entitled "MODULAR UNITHEADSET, to which reference was made above, describes an integrated system in which the parent electronic system connected to the PSTN network communicates with the headset in both a wireless and wired system by using a modular unit attached to it. Another patent application referred to above, entitled "ELECTRONIC EQUIPMENTA UDIO SYSTEM, describes a modular port equipped with a modular connector that can communicate with a microphone in a wireless and wired system.

Therefore, it is clear that the improvements presented are aimed at increased interaction and modular integration of a number of devices, which is expected to contribute to convenience of use.

The method of establishing a communication line in a wireless local communication system, equipped with a mobile station associated with a cellular mobile telecommunications network, a radio base station associated with a fixed public switched telephone network, a wireless headset, adapted to communicate with at least one mobile or radio station base station, each mobile station, the radio base station and the wireless headset are connected to a separate local coupling module, according to the invention it is distinguished by determining whether the mobile station is in the first broadcasting range of the radio base station, the first wireless local path between the mobile station and the radio station is selectively established base station If the mobile station is in the first broadcasting range associated with the radio base station, if not, then it is determined if the mobile station is in the second transmission range associated with the wireless headset, a second wireless local path is selectively established between the wireless headset and the mobile station, if the mobile station is in the second transmission range associated with the wireless headset, and if not it is determined whether the wireless headset is in the first broadcasting range associated with the radio base station, a third wireless local path is selectively established between the wireless headset and the radio base station if the headset is in the first broadcasting range associated with the radio base station, each, the first, second and third local wireless path being established on the basis of a common local communication protocol .

A system for establishing a communication line in a wireless local communication system between a first locally located communication device and an external communication system, part of which is a locally located headset, where the locally located communication device and the locally located headset are located in a certain local area, according to the invention is distinguished by having the first local coupling module, operably connected to a locally located, first electronic communications device, and a second local coupling module, operably connected to a locally located, wireless headset.

The wireless headset is preferably equipped with a transceiver coupled to the antenna and a driver for controlling the transceiver, connected to the transceiver and amplifier of local communication signals received by the transceiver, located inside the housing, operatively connected to the sender device z - receiving and additionally with a handset equipped with a loudspeaker, microphone and power source located inside the housing.

The solution according to the invention allows the use of a cellular station equipped with a modular unit that can communicate with the base station of a cordless telephone, so that it can be an extension of the cordless telephone, which in turn

183 758 gives you the opportunity to communicate over a larger area. It is also beneficial to use a wireless headset that can communicate using one protocol with both the cellular telephone station and the base wireless telephone station. Thanks to such a system, the operator can operate various telecommunications devices, without having to replace various modular units. An important improvement is also the integration of an electronic data terminal, capable of transmitting and receiving sound signals, with the local area communication system (LACS for short), which further increases the usability of the terminal. It is obvious that such a terminal can be a computer, which in turn can be an independent device or connected to a local area network (LAN for short), fax machine, pager, printer or handheld electronic notebook. It is also beneficial to integrate a typical answering machine with LACS, enabling the playback of a greeting signal, a recorded message, as well as recording it.

The invention includes a local communication system (LACS) comprising a number of locally located communication devices of which any two can be selectively connected via the chosen means of communication. At least one of them can connect to an external or non-local communication network. Each of the locally located communication devices is equipped with a local coupling module that receives the incoming signals and converts them into local communication signals. Such signals can be transferred using at least one selected and commonly used protocol. According to a preferred embodiment of the present invention, the incoming signal or local communication signal can be either analog or digital, modulated using known methods. Both signals may be sound, vision, data or a combination thereof. A local interface module can be placed in the system of the respective communication device. According to an alternative solution, this module can be connected to the module port in the appropriate communication device.

The invention includes at least one cell phone station connecting to a cellular network, at least one telephone interfacing device (abbreviated PID) connecting to a public switched telephone public switching telephone network, abbreviated PSTN), at least one electronic data terminal and one unit that does not require manual operation. The specialist is aware that such a terminal may be a computer selectively connecting to the network, a printer, a pager, or a handy electronic notebook. Such a terminal, according to another aspect of the present invention, may be an answering machine. However, the computer can be a multimedia computer with a graphical, audio, video and data interface. PID, on the other hand, can be a radio connecting device or a traditional corded telephone equipped with a headset connecting to the camera via a cable. Each of these devices connects to a local coupling module including a transceiver to selectively create a local connection between the local coupling module of which it is part and any other local coupling module. The radio connecting device may be a traditional wireless telephone base unit connecting to the local coupling module, or alternatively, a local coupling module connecting directly to the PSTN and referred to as its own base station. This own base station can be equipped with a keypad for connection.

LACS together with a mobile phone station, acting selectively as a cordless telephone handset, enables calling and answering the phone via PSTN. The wireless headset selectively plays the role of a wireless extension of a mobile phone station or a remote unit that does not require manual operation and connects to the radio connecting unit associated with PSTN. Another advantage of the present invention is the integration into the LACS of an electronic data terminal as described above. Another advantage is the use of two headsets, preferably wireless, which

183 758 can connect locally to each other or to another locally located device using a common protocol.

Figure 1 shows the network connections of the integrated local communication system (LACS), according to the present invention, numbered 100. This system combines a number of electronic communication devices, 110-1 - 110-N, at least one of which can connect to an external communication network, marked with numbers 140-1 to 140-4. Connections 130-1-130-4 between individual devices 110-1-110-4 and external communication systems 140-1 -140-4 may be in a wireless form or use wires in accordance with the present invention.

Figure 1 also shows a number of local coupling modules, 120-1-120-N, which connect to 110-1-110-N devices. According to a preferred example embodiment of the present invention, each of the 120-1 -120-N modules allows a wireless connection to other N-1 local coupling modules. According to the present invention, sound, image, data or any combination thereof may be transmitted as part of local communication. What's more, the local connection is made using one protocol using a local means, which can be electromagnetic waves, such as radio waves, infrared waves, optical waves or also microwaves, or magnetic waves or the wires themselves. The local signal can be in analog or digital form, and it can also be modulated in any known manner.

Figure 2 is a block diagram of a preferred embodiment of the present invention as 200. The number 210 is a radio connecting device which in turn connects to the public switched telephone network (PSTN) 260. According to one aspect of the present invention, the radio connecting device 210 may be a typical cordless telephone base unit that provides limited communication capability and is used in private homes and offices.

183 758

In Fig. 2, the number 240 indicates a typical mobile phone station connecting to the public cell phone network (PLMN) 270. The number 230, however, refers to the electronic data terminal as described above and which can connect to the local area network (LAN) 280. The average specialist knows the point is that many changes and modifications can be made to the electronic data terminal 230. For example, it can be a computer that selectively connects in a distributed computing environment. Alternatively, it can also be a printer, fax machine, pager, answering machine or handheld electronic notebook. According to the idea of ​​the present invention, changes and modifications of the terminal 230 can be used in the local communication network. Whereas the number 220 in fig. 2 means a wireless headset that, according to the preferred example solution, allows you to increase the convenience of the user creating a local communication path. The numbers 250-1 - 250-4 refer to four local coupling modules. The local coupling module 250-1 connects to the radio connecting device 210, the local coupling module 250-2 connects to the wireless headset kit 220, the local coupling module 250-3 connects to the electronic data terminal, and the local coupling module 250-4 connects with a 240 cell phone station. The skilled person will appreciate the fact that although local 250-1-250-4 coupling modules are presented in separate blocks, they can be integrated with communication devices 210, 220, 230 and 240. Furthermore, the radio connection device 210 may be of the type that its the 250-1 local coupling module can be integrated with its native connections. Similarly, it is also possible, in accordance with one aspect of the present invention, to integrate wireless headset 220 and local coupling module 250-2.

Figure 3 illustrates the use of a local communication system in accordance with one aspect of a preferred embodiment of the present invention. The number 210 is a radio device that connects to the PSTN, which enables external communication. The number 261 denotes the path connecting PSTN 260 to the radio connection device 210. The signals sent along this path can be analog or digital. According to a special solution, this path can be a T1 telephone line, an integrated service network (ISDN) or an asymmetrical digital subscriber line (Asymmetric Digital Suscriber Line, or ADSL) for high capacity. The radio connecting device 210, equipped with a local antenna 211 for local communication, can be a base unit of a wireless telephone connected to the appropriate local coupling module (not shown) or a directly connecting own base station.

The 240 mobile phone station connects to PLMN 270, which enables communication via a mobile phone. The path of such a connection 271 may be created between the cell phone station 240 and PLMN 270 using one of the commonly used cellular standards, such as AMPS (Advanced Mobile Phone Service), System Standard or GSM (Global System for Mobile Communication Standard). The 240 mobile phone station is equipped with a 242 non-local antenna that enables transmission and reception of signals between the 240 station and the base station (not shown in the figure). The station 240 further connects to a local coupling module 241 provided with an antenna 243 enabling local communication. The connection between station 240 and the local coupling module 241 is such that the signals of non-local cellular communication transmitted along the path 271 are selectively converted into local communication signals and vice versa. This enables them to be transmitted via a local communication link, which will be described below.

Wireless headset 220 works either as a wireless extension of station 240 via the first local communication radio link 310, or as a telephone unit that does not require manual operation, enabling communication via PSTN 260 using the second local communication radio link 320. A third radio link 330 is created selectively between station 240 and the radio connecting device 210, with station 240 acting selectively as a telephone unit

183 758 requiring manual operation and connecting to the 210 radio connection device, which allows access via PSTN 260.

In Fig. 4, the number 410 indicates a possible network connection of public cellular networks PLMN 270A, 270B with the public switched telephone network PSTN 260, in accordance with one aspect of the preferred embodiment of the present invention. A subscriber to a mobile telephony (MS) 420 network connects to one of the PLMN networks, which is his own PLMN 270A network. Within each pLmN 270A, 270B network there are a number of 470A, 470B cellular network exchanges (MSCs) serving areas within the network's coverage. The 420 subscriber supported by his own PLMN 270A network has the ability to connect to other wireless and wired terminals, connecting to the PSTN 260 network via the 430A link (GMCS). The access tandem (AT) 440 included in the PSTN 260 network routes the signals of mobile phones originating from the PlMn 270A network to wired terminals operated by one of its exchanges within the PSTN 260 network or to another PLMN 270B network through its GMCS 430B link. In the situation when the subscriber 420 is outside the range of his PLMN 270A network, but within the range of the neighboring PLMN 270B network, there is an exchange between the PLMN 270A network and the neighboring 270B, thanks to which the MS 420 continues to use services, now the 270B network, thanks to the so-called "roaming".

Figure 5 is a block diagram of a PLMN 270 network including a 470 cellular network switchboard. In addition, PLMN 270 includes a subscriber recording device of a given HLR 480 network, a subscriber recording device from outside a given VLR 490 network and a number of antenna systems 500-1 to 500-M. The 470 cellular telephone exchange is also known as a base station system. It includes a 510 base station controller and one or more transceiver (BS) 520-1 to 520-L base stations. Each transceiver station is connected to a subgroup of 500-1 to 500-M antenna systems. Placing subscriber 420 in your own network requires registration in HLR 480. Whenever the MS 420 turns on the device, it is possible that and at regular intervals after that, registration in the PLMN 270 network will take place giving the location.

MSC 470 connects directly to HLR 480 and VLR 490 to obtain subscriber information and forwards call signals from one BS to another while MS 420 travels while remaining within PLMN 270 network coverage. GMCS 430 operates on a link basis, enabling access to other wired terminals connected to PSTN 260 or connecting to mobile subscribers connected to other PLMN networks.

Connection using a mobile phone within the PLMN 270 network, as well as outside it, usually takes place thanks to the SS7 network protocols (signaling system number 7, Signałing System No. 7) using network addresses. An American patent application, entitled "IDENTIFICATION OF MOBILE CALLS WITHINA MOBILE TELEPHONE SYSSEM, registered on December 22, 1995, to which reference was made above, describes the method and system for using network addresses to construct a mobile number identifier.

Figure 6 is a block diagram of a typical telephone, designated by number 610. This telephone includes the 6351 handset 645. The telephone 610 connects to PSTN 260 via a 615 cable that allows the transmission of analog or digital signals. It should be noted that the wire connection 615 may be the same as the connecting path 261 as shown in Figure 3 and described above. The 635 includes a Data Access Arrangement section 620 (DAA for short), a 625 key pad (KEYPAD), and a 630 ringer circuit (RINGER CIRCUIT). The 645 handset includes a SPEAKER 640 speaker and a microphone (MICROPHoNe) 650 The DAA 620 includes analog filters and other known protective devices necessary to connect to PSTN 260. The 625 keypad is used to dial the number when connecting to PSTN 260. The 630 ring circuit and associated known signaling means are used to notify the user of the telephone to be picked up.

Figure 7 is a block diagram of a typical cordless telephone base unit designated by number 710. It can operate, for example, in or near 46 to 49 MHz. The base unit of the 710 cordless phone is submimature

183 758 mobile phone system. It is equipped with at least a channel for transmitting signals similar to a typical channel for transmitting signals in a mobile phone. He also receives instructions from the remote hand-held unit 715.

The 710 base unit is equipped with a 720 link with a local line (LOCAL LENE INTERFACE), a 730 link with a remote unit (REMOTE UNIT INTERFACE) connecting to the 770 antenna, a channel switch (CHANNEL SWITCH) 740, an audio signal source (TONE SIGNAL SOURCE) 750 , generating sound signals, such as a ring signal, and the controller (CONTROLLER) 760. Channel switch 740 selectively opens the channel between the 720 link with the local PSTN line and the 730 link with the remote unit, and the channel between the 750 sound source and the 730 link with the remote unit. It is known in the art that a 720 connection with a local PSTN line may include a hook loop (not shown) that can open and close the loop, a telephone signal detection circuit (not shown) and a transmitter (not shown) for sending dialing signals. It is also known from the prior art that the 730 link with the remote unit includes the audio tape processing circuit (not shown), mixer (not shown), radio transceiver (not shown) connecting to the 770 antenna. 760 controller controls operation of the 720 link with a local PSTN line, channel 740 switch and 730 link with a remote unit.

In Figure 8, 810 is a block diagram of a wireless headset in accordance with one aspect of the present invention. The 820 antenna, adapted to receive and transmit local communication signals using either standard wireless communication protocols or proprietary protocols, is electronically connected to the 830 radio transceiver. It is known in the art that the functionality of the 830 radio transceiver can be improved in many ways, for example by using electronic tuning and so on.

The signal output from the radio transceiver 830 shown in Fig. 8 is fed to the 840 baseband modulator / demodulator (BASEBAND MODULATOR / DEMODULATOR), which either retrieves information signals from the local radio carrier wave or modulates the local radio carrier wave using the signal information. The incoming signal is delivered to the 880 speaker via the preamplifier / amplifier 850. It is known in the art that the 880 speaker and preamplifier. The 850 amplifier can take various forms. The outgoing information signal is generated by the 870 microphone and amplified by the preamplifier / amplifier 850 system. The amplified signal is then modulated by the local radio carrier wave, which allows local transmission via local means. According to the preferred solution, the 860 controller is used, which connects to the 830 radio transceiver, baseband modulator / demodulator 840, preamplifier / amplifier 850, which allows supervision of two-way communication of information signals. In accordance with one aspect of the present invention, the controller assembly 860 may include a microprocessor, a number of control buttons, memory, and / or digital circuit logic. According to a further aspect of the present invention, the wireless headset may include one housing together with a separate keypad and corresponding control buttons and a portable power source such as a battery. According to another aspect, the wireless headset may include two headphones, a pivoting microphone, movably attached to the housing, a volume control allowing for natural sound, and an additional strap that prevents the headset from sliding off the head. According to a preferred embodiment, the antenna 820 can be placed on a swinging arm on the microphone 870, although in another aspect this antenna may be attached to one of the headphones, sliding out of its housing. Instead of a typical switch, you can use a voice-responsive mechanism that makes it easy to connect and disconnect as part of local communication with the headset. It is also beneficial that the headphones are made of flexible rubber or plastic material so that they adapt to the shape of the ear, minimizing the amount of noise coming from outside. As an alternative solution, the headphones may be hollow

183 758 cushions similar to those that allow high fidelity reproduction, which further reduces outside noise. A wireless headset can also have a specific look, depending on the aesthetic tastes of the designer.

Figure 9A is a block diagram of a preferred example solution of a local coupling module adapted to be used with a cell phone station 240 (not shown) connecting the PLMN 270 network (not shown). Fig. 9B is a block diagram of a preferred example solution of a local coupling module that performs the function of directly connecting to its own base station connecting to PSTN 260. Fig. 9C is a block diagram of a preferred example solution of a local coupler module connected to a serial port. Fig. 9D is a block diagram of a preferred exemplary solution of a local coupling module used together with electronic data terminal 230. FIG. 9E shows a block diagram of a preferred example solution of a local coupling module used with the cordless telephone base unit 210 connecting to PSTN 260.

Speaking of local connecting modules, 905-A to 905-E in Figures 9A to 9E, it should be noted that, according to the preferred example embodiment of the present invention, these modules are essentially the same, and also resemble to a large extent the wireless headset shown in Fig. 8. As described above, the antenna 820 can receive and transmit local communication signals using either standard local communication protocols or proprietary protocols and one local communication center, which may be electromagnetic waves, infrared waves, radio waves, microwaves, magnetic waves, optical waves or even wires. Signal modulation and demodulation is done by means of a baseband modulator / demodulator 830 that connects to the coupling block 910-A to 910-E. The coupling block 910-A (iNtERFACE TO MOBILE PhONE - mobile phone link) is responsible for the proper transformation of communication signals between the local 905-A coupling module and the 920 system connector (SYSTEM CONNECToR TO MOBILE STATION - a system connector with a mobile phone station), associated with a 240 cell phone station (not shown). The coupling block 910-B (INtERFACE TO PSTN - link with PSTN) is responsible for the proper conversion of communication signals between the directly connecting local coupling module 905-B (or own base station as described above) and PSTN 260. The coupling block 910- C (INTERFACE TO SERIAL PORT) is responsible for the proper conversion of communication signals between the local 905-C interface module and serial port 930 (SERIAL CONNECTOR). According to one aspect of this invention, the serial port 930 may be, according to a preferred embodiment, an RS-232 connector. Alternatively, the 910-C coupling block may be compatible with the PCMCIA standard, as described in the known solution.

The 910-D (INTERFACE TO ELECTRONIC DATA TERMINAL) link is responsible for the proper conversion of communication signals between the 905-D local coupling module and the 935 (ELECTRONIC DATA TERMINAL) electronic data terminal. The 910-E (INTERFACE TO CORDLESS PHONE BASE UNIT) link is responsible for the proper conversion of communication signals between the local 905-E coupling module and the 210 (CORDLESS PHONE BASE UNIT) base unit that connects from PSTN 260.

According to a preferred embodiment of the present invention, each of the local coupling modules 905-A to 905-E may be located inside the housing of the communication device (not shown) to which it is to be connected. According to an alternative solution, the local coupling module may be placed in a separate housing, thus creating a separate unit connected to the module port in the communication device. As mentioned above, the driver module 860 in Fig. 9A to 9E is substantially similar to the controller module 860 shown in Fig. 8.

Figures 10,11A and 11B are two flowcharts showing exemplary decision diagrams that can be used in accordance with the present invention and that show how wireless local communication occurs at least between a radio connecting device, a cell phone station and a wireless headset . Due to the purpose of this invention, which is the maximum user convenience and flexibility of the solution, different decision patterns corresponding to the specific conditions of use can be used.

Figure 10 is a flowchart of selective creation of local wireless communication upon telephone reception. Steps 1005 to 1020 show decision blocks in which it is determined whether the connected telephone comes from the PSTN network (PSTN CALL? - is it a telephone whose signal is transmitted through the PSTN network?) Or is it a conversation from a mobile phone signals are sent via PSTN. For the second type of telephone, the user must determine whether the receiving device is to be a mobile phone station or a headset (MS OR HEADSET? - mobile phone station or headset?). This decision is presented in block 1010. If the cell phone station is in the range of the radio transceiver unit of the local coupling module connected to the radio connecting device, and the user decides to use the cell phone station to pick up the phone whose signal is transmitted by PSTN, he chooses the path MS marked number 1011 After making this decision, the user can selectively create a wireless local connection between the cell phone station and the radio connecting device, as shown in block 1015 (SELECTABLY ESTABLISH LOCAL LINK WITH MS - selectively create a local connection to MS). However, if the cell phone station is out of range to be able to connect to the radio connecting device, or if the user wants to receive the PSTN phone from the wireless headset, he chooses the headset path (HEADSET

- headset) 1012 to, at step 1017 (SELECTABLY ESTABLISH LOCAL LINK WITH HEADSET - selectively create a local connection to the headset) selectively create a wireless local connection between the wireless headset and the radio connecting device. However, if the headset is out of range, or you do not want to use it, you can proceed as in step 1016 (RECEIVE CALL by HANDSET IF PROVIDED - use the handset, if available, when answering the phone), answering the PSTN phone , using a typical, wired or wireless handset, thus selecting path 1018.

If the received call signal comes from a mobile phone, which is determined in step 1080 (CELLULAR CALL? - does the signal come from a mobile phone?), The user can use a mobile phone station to answer the phone in a typical way, as shown in block 1025 (RECEIVE CALL CONVENTIONALLY WITH MS? - answer the phone using MS?). It can also create a wireless local connection between a cell phone station and a wireless headset, provided they are at an appropriate distance from each other. The tan stage is marked with number 1040 (SELECTABLY ESTABLISH LOCAL LINK WITH HEADSET? - do you selectively create a local connection to the headset?).

Figures 11A and 11B illustrate an exemplary decision scheme corresponding to merging in accordance with the idea of ​​one aspect of the present invention. Decision blocks 1105 (PSTN CALL?

- will it be a phone with a signal sent via PSTN?) and 1185 (CELLULAR CALL? - will it be a call from a mobile phone?) allow you to specify whether the call signal should be sent via PLMN or PSTN. In the case of a PSTN telephone, the user selects YES (yes) 1104. Then he chooses between a wireless headset with a keypad and a mobile phone station, as shown in block 1110 (MS OR HEADSET? - MS station or headset?). By deciding to use the MS station, which is in addition in the local range of the radio connecting device, he can, by choosing path 1112, create a selectively local connection between

183 758 mobile phone station and radio connecting device, as shown in block 1121 (SELEcTaBLY ESTABLISH LOCAL LiNk WITH MS - selectively create a local connection to the MS station). If, however, the user wants to use the headset by selecting track 1111, the next steps depend on whether the wireless headset has its own keypad necessary to perform the remote operation. The appropriate test is carried out at step 1115 (hEaDSET WITH KEYPADS? - does the headset have a keypad?). If the answer is negative (NO), the user selects path 1116 to connect using the PSTN network and the radio connecting device keypad, as shown in block 1117 (INITIATE CALL USING PHONE INTERFACING DEVICE KEYPAD - connect using the connecting device keypad). Then the user can return via track 1118 to use the wireless headset in step 1119 (SELECTABLY ESTABLISH LOCAL LINK WITH HEADSET - selectively create a local connection to the headset), which can also be reached via path YES 114 from decision block 1115. Alternatively, unless the user selects either a cell phone station or a wireless headset, the PSTN phone number can be selected using a typical handset, if it is equipped with a radio connection device, as shown in step 1120 (eStABLISH PSTN CALA WITH HAnDsET IF PRVIDED - to make a call, connect to the PSTN network using the handset, if available.

However, if the call is to be made using a cellular telephone network, which selection is made at step 1125 (CELLULAr CALL? - a telephone using a cellular telephone network?), The user decides whether to use the headset or the cellphone station. If such a set is out of range (step 1135 HEADSET IN RANGE? - is the headset in range?) Or is not equipped with a keypad, the user uses the MS station, as shown in block 1165 (INITIATE CELLULAR CALL WiTh MoBILE STATION - connect through the cellular network using the MS station) accessed via path 1141 or 1136. After connecting in this way, the user can return to the headset via path 1172, or continue (step 1170 CONTINUE? - continue?) To use the MS station, as shown in step 1175. Similarly, by selecting the path YES 1142 (yes) when answering question 1140 (HEADSET WITH KEYPADS? - does the headset have a keypad?), The user can create a local connection between the headset and the mobile phone station, as shown in step 1160 (SELEcTaBLY ESTABLISH LOCAL LINK WITH HEADSET - selectively create a local connection to the headset). Although preferred examples of the method and apparatus of the present invention are shown in the accompanying drawings and described in detail above, they are not a limitation of the present invention. It is possible to carry out a number of changes, modifications and replacements without departing from the spirit of the present invention as set out in the claims. For example, local communication paths can use infrared waves, microwaves or magnetic fields. Instead of radio transceivers, you can use the appropriate receivers / transmitters. The term "radio transceiver" also refers to the corresponding radio control logic, enabling the transmission of signals using wireless communication standards such as DAMPS, GSM, DECT and others. The transceiver device may include, next to the transmitter and receiver, a modem when the communication device is used for data transmission. Both local and non-local signals (that is, located between a number of communication devices and appropriate external networks) can be analog or digital and transmit sound, vision and data. The skilled person understands that the aforementioned modifications and changes regarding the local communication system (LACS), allowing local connections between several communication devices using one center, do not go beyond the idea of ​​the present invention.
