Description

The device and system for combining GSM-telephones for use with Internet telephony is applicable in communications, and in particular for universal connection via GSM telephones in and through the Internet.

BACKGROUND OF THE INVENTION

There are no known devices for pairing GSM-phones for connecting via Internet-telephony through the voice channel of the GSM-network.

The usual method of using Internet telephony, which is implemented in conjunction with any of the protocols Skype, MSN Messenger, Yahoo! Messenger, Google Talk, Voip Buster, Voip Discount, Voip Cheap, Gizmo Project, etc. require users to be right next to their computers. In this case, user-generated sound waves interfere with a microphone that generates an analog signal. The microphone is plugged into the sound card of the computer that digitizes this analog signal, after which the digitized signal is converted to the format needed to send it through the Internet to one or more computers, where the sound card converts the signal from digital to analog and, through the speakers connected to the sound card, provides a sound signal that is accessible to auditory perception by users.

This use implies lack or very little mobility for users using Internet telephony, since the microphone and speakers must be wired or wirelessly connected to the computer, and in both cases they must be close to the computer.

Some degree of mobility is achieved by using a mobile computer connected wirelessly to the Internet. But wireless computer networks have limited coverage.

Even greater mobility is achieved through the use of smart phones, which have an operating system that allows the installation and use of inter-telephony applications. But these phones are expensive, and the data network of GSM networks has a lower priority than voice. This limits the use of the data channel when the network is heavy.

A system for combining GSM telephones for use with Internet telephony is known [appl. US 2006/0233157 A1], consisting of specialized GSM telephones, additionally provided with a specialized operating system and specialized software for combining with the data channel of the GSM network through which the network is connected via Internet telephony.

The disadvantage of this known system is that it is of limited use because:

- requires specialized GSM phones;

- requires a specialized operating system in the GSM-phone;

- requires the installation of specialized Internet telephony software in the GSM-phone;

- low reliability of the transmitted data due to the lower priority of the GSM data channel over the voice channel;

- the data channel used makes the connection more expensive.

Of these, the disadvantage is that the GSM phone and the system are of high cost.

Another similar system for combining GSM telephones for use with Internet telephony is known [EP 1439675 A2], also consisting of specialized third-generation GSM telephones, which are factory provided with a specialized operating system for data channel combining of a GSM network through which the network connects via Internet telephony. This system has the same disadvantages as the previous one.

The aforementioned sources are known devices for combining GSM telephones for communication via the Internet telephony, which are only for connection through the data channel of the GSM network.

Utility model action

The device and system for combining GSM-phones for Internet telephony work as follows.

To use standard GSM phones-9 _p for calls over internet domain 3 is necessary audio signal, which is transmitted in the specific format of a given protocol for Internet telephony (minutes of Skype, MSN Messenger, Yahoo! Messenger, Google Talk, Voip Buster, Voip Discount, Voip Cheap, Gizmo Project, etc.) to be converted to GSM telephony in order to be sent to any standard GSM telephone 9. This conversion, according to the utility model, is carried out by the device - in its various modifications - to combine GSM-phones to work with Internet-telephones the one.

In order to establish a connection between a user with a GSM telephone 9 and an Internet telephony user 16 on a computer from the multiple computers 2 _pc of the GSM telephone 9, the personal GSM number of the GSM module 5 in the device Y1 is dialed (Fig. 1) . A telephone connection is established between them through the GSM network 10 and voice communication is initiated as follows: the microphone of the GSM phone 9 receives sound waves that are fed to the analog input of the audio codec of the GSM phone 9, which converts the signal into digital and submits it to the GSM processor of the GSM telephone 9. The data is then encoded according to the protocols used in the GSM standard and sent to the GSM network 10 via the antenna of the radio module of the GSM telephone 9. In the U1 device via its radio antenna module 5.3 captures the information sent and transmits it to GSM microprocessor 5.2, where data is decoded and transmitted to audio codec 5.1. It converts the signal from digital to analog. The analog signal is transmitted to the analog audio input of the audio converter 4, where it is digitized again to be transmitted to computer 2 via the standard interface 1. In computer 2, this signal is converted to the format for internet telephony protocol 16 and sent via internet 3 to internet telephony user 16 on a computer of multiple 2 _pc In the opposite direction, the sound waves are received from the microphone to a computer 2 ^ by the plurality of 2 _K , and then transmitted as an analog signal to the sound card of the computer 2 ^, where they are digitized, passed through the encoding of the respective Internet telephony protocol 16 and sent via the Internet 3. Reaching computer 2, the data is decoded and transmitted through computer interface 1 to the audio converter 4, where it is converted to an analog signal. From the analog output of the sound converter 4, they are transmitted to the audio codec 5.1 of the GSM module 5, which digitizes them and feeds them to the GSM processor 5.2. In it the data is encoded in accordance with the protocol of the GSM standard and through the radio module 5.3 and the antenna connected to it, are sent through the GSM network and 10 to the GSM phone 9. In it the data is decoded, converted to an analog signal and through the speaker on the GSM-phone 9 are played as sound.

The microprocessor 6 receives and processes information about the operation of the sound converter 4, the GSM module 5 and interface 1. The indicator unit 7 at the command of the microprocessor 6 serves to display connectivity information: in GSM network 10; internet telephony 16; to computer 2. This information is required during operation and when setting up the Y1 device. The power supply unit 8 supplies the required voltage to all modules of the unit Y1. Since at the initial moment of switching on, the GSM module 5 has a high power consumption until it establishes a connection to the GSM network 10, the power is supplied sequentially with some delay to the other blocks at the command of the microprocessor 6.

This is how GSM-phones are combined to work with high-efficiency Internet telephony; since the voice channel of the GSM network 10 is prioritized over the data channel. This reduces the risk of lack of communication in case of increased load on the GSM network 10.

Voice quality is improved as the audio signal is not subject to additional conversions in the GSM phone 9.

For the same reason, it is possible to use GSM phones 9 of all generations, including the low-end microprocessor limited capabilities.

The U2 device (Fig. 2) operates in the manner described for the U1 except that the ability of the GSM network 10 to divert connections is used when the dialed GSM number is busy. When the device U2 is initially connected to the GSM network 10 via each of its GSM module 5sh, the option "conditional divert" is set in this network, ie, if the dialed GSM number is occupied, the GSM network 10 redirects the call consecutively to the others. GSM numbers of the GSM modules 5M until a free module 5 is found and the connection is made. At the same time, splitting the GSM Phones 9 _p into M groups allows further speeding up of the connection, since the forwarding can start from any GSM module 5 _t . GSM-telephones 9 _n may be evenly divided in the groups M. In the groups may have a different number of GSM-phone 9 _in. For example, some of the 9 _n GSM phones may be alone in a group, i. be privileged and have more phones in other groups. When calling from a GSM-phone 9p of the personal GSM-number of a GSM-module 5t, its signal falls into the GSM-module 5t to which the group m belongs. If this GSM module 5t is not currently connected to another GSM telephone _9n in its group, the call is received and the signal is processed in the manner described for U1. Then, the analog input and output of the respective audio codec 5.1sh are connected to the respective audio output and input of one of the sound converters 4t through the multiplexer 11. The microprocessor 6 determines which of the sound converters 4sh to make this connection through the multiplexer 11. Namely, the microprocessor 6 continuously monitors which of the 4m sound converters are busy or free. Once the 5.1c audio codec of the GSM module 5sh is connected to the 4t audio converter, communication proceeds as described for the U1 method. If the corresponding GSM module 5t is busy during the call, due to the pre-selected "forwarding" option, the GSM network 10 sequentially searches for the other GSM modules 5 until it is free and the connection is made.

The UM device works like U1 with the difference that when making a connection between the GSM phone 9 and the GSM module 5, the desired destination for the call is recognized and if it is a fixed telephone post 15 connected to a telephone network 14 to which is connected to the SLIC module 12, then the microprocessor 6 sends a command to the SLIC module 12, which dials the individual number of the telephone post 15. After connection between the SLIC module 12 and the telephone post 15, the microprocessor 6 sends a command to the multiplexer 11, which connects the analog input and the analog output and codec 5.1 to the corresponding analog output and analog input of the SLIC module 12. The analog signal from the output of codec 5.1 is then fed to the analog input of the SLIC module 12, where the signal is converted to the standard of the telephone network and sent to the fixed telephone post 15. In the opposite direction, the signal from the fixed telephone post 15 reaches the SLIC module 12, from which the analog output reaches the analog input of the codec 5.1.

In case the call from the GSM-phone 9 is addressed to a subscriber of another fixed telephone network other than the telephone network 14, the microprocessor 6 sends a command to the multiplexer 11, which connects the analog input and the analog output of the codec 5.1 to the corresponding audio output and input of the audio converter 4. The communication then proceeds as described for the U1 method.

When a landline subscriber wants to connect to an internet telephony subscriber 16, the standard way to make a call through a typical telephone network 14 is that the telephone post 15 dials the personal telephone number 13. After the connection is made, from telephony post 15 is dialed the Internet telephony connection code 16, which enters the microprocessor 6 via the SLIC module 12. After recognizing this code, it sends a command to the multiplexer 11, which connects the analog input and the analog output of the SLIC module. 12 to resp Nittel analog output and input of the converter sound 4. Audio signal obtained in the SLIC-module 12 is transmitted to the multiplexer 11 in analog form, where it is sent to the converter sound 4. Further communication takes place as described for S1 way.

When a landline subscriber wishes to connect to a GSM telephone 9, by default, the telephone post 15 dials the personal telephone number 13. After the connection is made, the telephone post 15 15, the dialing code is dialed through the GSM network 10, which enters the microprocessor 6 via the SLIC module 12. It, in the manner described above, sends a command to the GSM module 5, which dials the individual telephone number of the GSM telephone 9 _p . At the same time, the microprocessor 6 also sends a command to the multiplexer 11, which connects the analog input and the analog output of the SLIC module 12 to the corresponding analog output and analog input of the codec 5.1. The audio signal received in the SLIC module 12 is transmitted to the multiplexer 11 in analog form, from which it is sent to the codec 5.1 of the standard GSM module 5. Further communication proceeds as described for Y1.

When the connection is between a GSM telephone 9 _n and an Internet telephony user 16 ^ 2, the multiplexer 11 connects the analog input and the analog output of the sound converter 4 to the corresponding analog output and analog input of codec 5.1, and communication proceeds as for U1.

When a user wishes to make a connection from a landline telephone 13 connected directly to the SLIC module 12, a landline telephone 13 is dialed and sent directly to the microprocessor 6 to the microprocessor 6 to indicate what type of call to make. If the command is to call an Internet telephony user 16, the microprocessor 16 sends a command to the multiplexer 11 to connect the analog input and analog output of the sound converter 4 to the corresponding analog output and analog input of the SLIC module 12. If the command is for making a call to a fixed telephone post 15, the audio signal from the fixed telephone 13, without passing through the multiplexer 11, is directly transmitted from the SLIC module 12 through the telephone network 14 to the fixed telephone post 15.

The U4 device operates in the manner described for the U2 method, and when the connection between the GSM telephone 9 _n and the GSM module 5 is made, the desired destination is recognized in the manner described for the UZ method. Additional action is that the microprocessor 6, but to continuously monitor the employment of converter sound 4m, monitor and Employment phones SLIC 13 _t to 12 _t-modules. The initial installation of the telephone numbers 13 _t in the telephone network 14 activates the "conditional forwarding" service (when the number is busy). When an incoming call from a fixed telephone line 15p to a busy 13 _t number is forwarded in the same way as in U2. Landline telephone posts 15n are also grouped according to the descriptions for GSM telephones _9n in the Y2 manner (Fig. 2).

The U51, U52, U53, and U54 devices operate as described for the U1, Y2, UZ, and U4 devices respectively, except that the digital signal from the sound converter 4 is fed to the microprocessor 6, and it is of a higher class and is capable of operating the operating system necessary to use the Internet telephony software 16. The microprocessor 6 encodes the signal according to the format of the Internet telephony protocol used 16. The encoded data is then sent to the Internet connection interface 1 for sending. The communication then proceeds as described for the devices Y1, Y2, KM and Y4 respectively.

Devices U61 and U62 operate in the manner described respectively for devices Y1 and Y2, with the difference that once the radio module 5.3 receives the data transmitted from the GSM-phone 9 _n in GSMmrezhata 10, the data is decrypted in the GSM-npotsesora 5.2, and then are sent to digital type to sound converter 4, which converts them to the appropriate transmission format according to the Internet telephony protocol used 16. The communication then proceeds as described for the U1 and U2 devices respectively. In the opposite direction, the data received from the computer 2 is sent digitally to the audio converter 4, which decodes it and sends it back digitally to the GSM microprocessor 5.2. The communication then proceeds as described for the U1 and U2 devices respectively.

The U71 and U72 devices operate in the manner described for the U61 and U62 devices respectively, except that the digital signal from the GSM microprocessor 5.2 is fed to the microprocessor 6, and it encodes the signal according to the format of the Internet telephony protocol used 16. The encoded then data is sent to interface 1 for connection to internet space 3 for sending.

Where a type 17 set of microphones and headsets is connected to the audio converter 4 or to at least one 4w audio converter in a U1, UZ, or U2 and U4 device for combining GSM telephones for Internet telephony, an on-site operator is possible where to get the device involved in communication. This allows the operator to use computer 2 for Internet telephony, for example when repairing and / or setting up the device.

The system for combining GSM telephones for Internet telephony (Fig. 13) allows GSM telephones 9 to be of all generations, and the used channel of the GSM network 10 to be the voice channel. This is because, between this voice channel of each GSMphone 9 and Internet telephony 16, sets of identical or different devices U, namely U1, Y2, Y51, U52, Y61, Y62, Y71, Y72, are connected in two ways 9 for use with Internet telephony 16 via the voice channel in the manner described above for each of them.

It is possible that when in the system for combining GSM telephones for use with Internet telephony (Fig. 14) some of the devices Y are also according to the claims UZ, U4, U53, U54, it is also for communication with fixed and telephones 13, and fixed landlines 15, as described above for each device U.
