Description

 The invention relates to mobile radio networks, and more specifically to digital mobile radio networks with packet information. The method can be recommended for use in mobile radio networks of generations 3G and 4G.

 A known mobile radio communication system (ed. St. SU 1474860, class N 04 B 7/26, 1989), in which two mobile subscribers carry out information exchange through the base station. However, the disadvantage of such a mobile radio communication system is its low throughput. This is explained by the fact that in the known mobile radio communication system, the total frequency resource of bandwidth is divided into separate channels by frequency and the total number of channels formed in this way, and therefore the number of subscribers who can simultaneously exchange information in the system, is limited by the width of the frequency spectrum .

 There is also a known method of transmitting and receiving information with code signal compression (ed. St. RF 2014738, class H 04 J 11/00, 1994), in which two mobile subscribers carry out information exchange through the base station in duplex mode.

 When applying the known method of transmitting and receiving information with code compression of signals for exchanging information between two mobile subscribers, the efficiency of using bandwidth is higher than in the known mobile radio communication system, since the total time-frequency resource of bandwidth is divided into channels by codes and the total number the communication channels formed at the same time, and consequently, the number of subscribers who can simultaneously exchange information is greater than in the mobile system radio communications. However, the disadvantage of the known method of transmitting and receiving information with code-division multiplexing of signals is the relatively low bandwidth, since in this case four communication channels are simultaneously used to provide information exchange between two mobile subscribers.

 The closest in technical essence to the claimed one is the method of messaging between two mobile subscribers, adopted in 3G mobile radio communication networks (see L.M. Nevdyaev. 3rd generation mobile communication. / Edited by Yu. M. Gornostaev, M .: Series of publications "Communication and Business", ICSTI, LLC "Mobile Communications", 2000, p. 159-163). With this method, a request signal is generated at the calling subscriber station, transmit it via the control channel to the base station. At the base station, a request signal is identified and a call signal is transmitted from the base station to the called subscriber station. At the called subscriber station, after receiving the call signal, a ready signal is generated, which is transmitted to the base station. At the base station, after receiving the ready signal from the called subscriber station, the communication channels with the specified parameters are isolated by the results of the identification of the request signal from the calling subscriber station. Then, a readiness signal is transmitted from the base station to the calling subscriber station, after which own corresponding information packets are formed at the corresponding subscriber stations, including address and information parts, and they are transmitted to the base station. At the base station they are identified and transmitted to the respective subscriber stations.

 The known prototype method partially eliminates the disadvantage of analogues regarding the low bandwidth of the mobile communication system. This follows from the fact that it provides for the use of separation of channels by frequency, time and codes. This makes it possible to increase the total number of channels in comparison with the known method of transmitting and receiving information with code compression of signals and, therefore, to increase the number of subscribers who can simultaneously exchange information.

 However, the disadvantage of the prototype method is the relatively low throughput due to the inefficient use of the formed communication channels. This is due to the fact that four communication channels are simultaneously used for the exchange between two corresponding subscriber stations: two direct communication channels from the base station to two subscriber stations and two feedback channels from subscriber stations to the base.

 The aim of the invention is to develop a method for exchanging messages in digital mobile radio networks with packet information, which increases the throughput of the mobile radio system by reducing the simultaneously used communication channels by one pair of corresponding subscriber stations.

 This goal is achieved by the fact that in the known method of messaging in digital mobile radio networks, which consists in the fact that the request signal is generated at the calling subscriber station, transmitted via the control channel to the base station, where it is identified, transmitted from the base station to the called subscriber call signal to the station, and after receiving it at the called subscriber station, a ready signal is generated, which is transmitted to the base station, at the base station according to the results of the call signal identification The communication channels with the specified parameters are allocated, and then a ready signal is transmitted from the base station to the calling subscriber station, after which they create their own information packets at the corresponding subscriber stations, including address and information parts, and transmit them to the base station, where they are identified and after identification transmit to the corresponding subscriber stations, additionally, at the corresponding subscriber stations, the information part of the generated personal information packets is stored dissolved. From their own information packets received at the base station, their information and address parts are extracted and the information parts extracted from their own information packets are converted into a code packet. After that, a single code packet is formed by kankenateniya code packet and address parts received from the corresponding subscriber stations of their own information packets. Then a single code packet is transmitted from the base station to the corresponding subscriber stations. At each subscriber station, the address part and the code packet are extracted from a single code packet, and then the information part of the correspondent's information packet is extracted from the code packet using the information part of its own information packet previously stored at this subscriber station. Then, at each subscriber station, the previously stored information part of its own information packet is erased and subsequent subsequent information packets are formed. After that, at each subscriber station, the information part of each subsequent information packet formed at this subscriber station is stored. Then all of the above actions are repeated with the next own packets of information until the completion of information exchange. In this case, a single code packet from the base station is transmitted to both subscriber stations via a common channel.

 The conversion of the information parts of its own information packets into a code packet at the base station and the allocation of the information part of its own correspondent information packet from the code packet at each subscriber station can be implemented in various ways. In particular, in the first version, for converting the information parts of their own information packets from the corresponding subscriber stations to a code packet at the base station, they are element-wise multiplied modulo two, and to extract the information part of their own information packets of the correspondent information at each subscriber station, the code packet is element-wise multiplied modulo two with the previously stored information part of its own information package.

 In the second option, for converting at the base station the information parts of their own information packets from the corresponding subscriber stations into a code packet, they are added element-wise. In this case, if the values of the folding elements of each pair coincide, a single value is assigned to the element of the code packet, and if it does not match, it is set to zero. To extract the information part of the correspondent’s own information package from the code package at each subscriber station, the code packet received at the subscriber station is added element-wise with the previously stored information part of the information package of its own. If the values of the combined elements of each pair coincide, the element of the information part of the correspondent’s own information package is assigned a single value, and if it does not match, it is set to zero.

 Thanks to the new set of essential features, namely, that when exchanging messages between two mobile subscribers at the base station, the information parts of their own information packets are converted into a code packet, at each subscriber station the information part of the correspondent’s own information packet is extracted from the code packet using the previously stored information part of its own information package, a reduction in simultaneously used communication channels is achieved. This follows from the fact that part of the direct communication channels from the base station to the subscriber stations is freed up by converting at the base station their own packets of information received from the subscriber stations into a single code packet and transmitting it to both subscriber stations via a common direct communication channel. This achieves a decrease in the number of direct communication channels used from the base station to the subscriber stations and, consequently, an increase in the throughput of the mobile radio communication system.

 The analysis of the prior art made it possible to establish that analogues that are characterized by a combination of features that are identical to all the features of the claimed technical solution are absent, which indicates the compliance of the claimed invention with the condition of patentability "novelty". Search results for known solutions in this and related fields of technology in order to identify features that match the distinctive features of the claimed object from the prototype showed that they do not follow explicitly from the prior art. The prior art also did not reveal the popularity of the impact provided by the essential features of the claimed invention transformations to achieve the specified technical result. Therefore, the claimed invention meets the condition of patentability "inventive step".

The claimed method is illustrated by drawings, on which are presented:
figure 1 is a functional diagram of a digital mobile radio communication system with packet data transfer that implements the claimed method;
in FIG. 2 - structure of control signals exchanged between subscriber and base stations during the connection, and the place of their formation;
3-8 are figures explaining the principle of the implementation of the messaging method in digital mobile radio networks with packet information transmission.

The implementation of the inventive messaging method in digital mobile radio networks with packet information transmission is explained using the example of the communication system shown in FIG. 1. The communication system is represented by base station 1 and two subscriber stations 2 ₁ and 2 ₂ , the first 2 ₁ of which is the calling (in Fig. 1 is indicated by the letter "A"), the second 2 ₂ is the called (indicated by the letter "B").

The base station includes n radio receivers 1.1 ₁ ... 1.1 _n , a conversion unit 1.2, m radio transmitters 1.3 ₁ ... 1.3 _m and a control device 1.4.

Radio receivers 1.1 ₁ . . .1.1 _n are intended for receiving own information packets from subscriber stations via feedback channels.

 The packet conversion unit 1.2 is intended for converting information parts of its own information packets into a code packet.

Radio transmitters 1.3 ₁ ... 1.3 _m are designed to transmit a single code packet over a common direct communication channel to subscriber stations.

 The control device 1.4 provides the interaction of all nodes of the base station, processes the request signals received from mobile subscribers, identifies them and, based on the identification of the request signals, selects communication channels with specified parameters, generates a call signal, allocates the address and information parts of its own information packets received from subscriber units stations, forms a single code packet. The control device constantly maintains a list of addresses of subscribers registered at this base station.

Each subscriber station includes a radio transmitter 2.1 ₁ , 2.1 ₂ , a radio receiver 2.2 ₁ , 2.2 ₂ , a storage unit 2.3 ₁ , 2.3 ₂ and an allocation unit 2.4 ₁ , 2.4 ₂ .

The radio transmitting device 2.1 ₁ , 2.1 _{2 is} designed to transmit its own information packets to the base station via the feedback channel.

The radio receiver 2.2 ₁ , 2.2 _{2 is} designed to receive a single code packet from the base station via a common direct communication channel.

The storage unit 2.3 ₁ , 2.3 _{2 is} intended for storing the information part of its own information packet generated at a given subscriber station, from the moment it is transferred to the base station until the end of the allocation of the information part of the correspondent’s own information packet.

The allocation unit 2.4 ₁ , 2.4 _{2 is} intended for extracting from the unified code packet its address part and the code packet, as well as extracting the information part of the correspondent’s own information packet from the code packet using the stored information part of its own information packet.

 The claimed method of messaging in digital mobile radio networks with packet information is implemented as follows.

If necessary, communication between two mobile subscribers at the calling subscriber station 2 ₁ (A) generate a request signal containing the signal "Request" and the addresses of the called and calling subscriber stations (see Fig. 2a). In FIG. 2-8 are indicated: AC _A - calling subscriber station A; AC _B - called subscriber station B; BS - base station.

 The generation of the request signal can be implemented by typing on the numeric keypad of the calling subscriber station A the addresses of the called subscriber station B, as provided for in all known subscriber stations of mobile radio communication networks (for example, in the GSM standard system).

 Each signal that is used in the process of establishing a connection between the calling and called subscriber stations is a sequence of binary symbols defined for a given signal.

 The request signal on the control channel of the base station is transmitted from the calling subscriber station A to the base station. In the control device 1.4, the addresses of the corresponding subscriber stations are extracted from the received request signal, and they are identified, thereby determining by the address of the called subscriber station B whether it is registered at this base station. To do this, check the availability of the address of the subscriber station B in the list of addresses of subscriber stations registered at the base station.

 Provided that the called subscriber station B is registered at the base station, a call signal is generated in the control device 1.4 containing the “Call” signal and the addresses of the called and calling subscriber stations (see Fig. 2b). The call signal on the control channel is transmitted to the called subscriber station B. In the event that the called subscriber station B is in the coverage area of this base station and if it is not turned off, after receiving the call signal on it, a ready signal containing the Ready signal and addresses calling and called subscriber stations A and B (see Fig. 2B). The generated ready signal is transmitted from the called subscriber station B to the base station via the control channel. After receiving the ready signal on the control channel of the base station 1 in the control device 1.4, channels with the given parameters are allocated from the channel resource available at the base station: two feedback channels and one direct (common) channel for providing information exchange of own information packets between the calling and called subscriber stations A and B (see Fig. 2d). Then, a ready signal is transmitted from the base station 1 to the calling subscriber station A.

After allocating direct and feedback channels at the base station and receiving a ready signal at the calling subscriber station A, the calling and called subscriber stations A and B form their own information packets containing the address and information parts (see Fig. 3a, c). The address part of its own information packet contains the addresses of the called and calling subscriber stations and is a sequence of binary characters. The information part of its own information packet is also a sequence of binary characters. Own information packets generated at the calling and called subscriber stations A and B have equal strictly defined (fixed) volumes V _A and V _B. After the formation of their own information packets at the calling and called subscriber stations A and B, the information parts of these packets are stored in storage units 2.3 ₁ , 2.3 ₂ (see fig. 3b, d), and the generated own information packets are transmitted using radio transmitting devices 2.1 ₁ , 2.1 ₂ through feedback channels to the base station 1.

Received in the radio receivers 1.1 ₁ , 1.1 ₂ (see figure 1) own information packets are identified in the control device 1.4. In this case, the addresses of the calling and called subscriber stations A and B are determined, the common direct communication channel assigned to them, and the information and address parts of the received own information packets are allocated. After that, in the conversion block 1.2, a code packet is formed from the information parts of the received own information packets (see Fig. 4a, Fig. 7a). Then, in the control device 1.4, by co-catenating the code packet generated in the conversion unit 1.2 and the address parts received in the radio receivers 1.1 ₁ and 1.1 ₂ from the calling and called subscriber stations A and B, their own information packets form a single code packet including the address and information parts (see figb, figb). At the same time, the address part of the single code packet contains the addresses of the calling and called subscriber stations A and B. The volume of the single code packet V of the _{BS is} strictly fixed and does not exceed the volume of its own information packets generated at the calling and called subscriber stations A and B:
V _BS ≤V _A = V _B.

The generated single code packet with the help of a radio transmitting device 1.3 _{1 is} transmitted to the calling and called subscriber stations A and B via a common direct communication channel. After reception by radio receivers 2.2 ₁ , 2.2 _{2 of a} single code packet in the allocation blocks 2.4 ₁ , 2.4 ₂ , the address part of the single code packet and the code packet are extracted from the single code packet. Then, in the allocation blocks 2.2 ₁ , 2.2 ₂ , the information part of the correspondent’s own information packet is extracted from the code packet (see Fig. 5a, b). This selection is carried out using the information part of its own package of information stored in storage units 2.3 ₁ , 2.3 ₂ (see figa, d). After the information part of the correspondent’s own information package is allocated, the information part of the own information package is erased in the storage units 2.3 ₁ , 2.3 ₂ . Moreover, the implementation of erasure in the storage units 2.3 ₁ , 2.3 _{2 of the} information part of its own information package is carried out in various ways. In particular, for this, the information part of the next proprietary information packet, or the “erasing” packet, which is formed in the absence of the next proprietary information packet, can be used for this. The volume of the “erasing” packet is fixed and equal to the volume of the information part of its own information packet. As a “erasing” packet, a “zero” packet can be used, all elements of which have a value equal to 0 (see Fig. 5c), or a “single” packet, all elements of which have a value equal to 1 (see Fig. 5d) . In principle, there may be other versions of the “erasing” packet of the informational part of the information packet in the storage blocks 2.3 ₁ , 2.3 ₂ .

 After that, at the calling and called subscriber stations A and B, the next own information packets are formed, the information parts of each subsequent own information packet formed on this subscriber station are stored and all of the above actions are repeated with the next own information packets until the information exchange is completed.

In the case of one-way transmission of one’s own information packets, for example, from the calling subscriber station A to the called subscriber station B, when the called subscriber station B receives information from the calling subscriber station A and does not transmit anything to it (it only works for reception) at the calling subscriber station stations A form their own information packet containing the address and information parts (see figa). The address part of its own information packet contains the addresses of the called and calling subscriber stations A and B and is a sequence of binary characters. The information part of its own information packet is also a sequence of binary characters. After the formation of its own information packet at the calling subscriber station A, its information part is stored in the storage unit 2.3 ₁ (see FIG. 3b), and the own information packet is transmitted using the radio transmitting device 2.1 ₁ via the feedback channel to the base station. At the called subscriber station B, their own information packet is not generated; in the storage unit 2.3 ₂ , the “erasing" packet is stored (see Figs. 5c, d). The feedback channel does not transmit its own information packet from the called subscriber station B to the base station.

Received in the radio receiving device 1.1 ₁ own packet of information from the calling subscriber station A is identified in the control device 1.4. In this case, the addresses of the called and calling subscriber stations A and B are determined, the common direct communication channel allocated for them, and the information part of the received own information packet is allocated. After that, a code packet is formed in the conversion block 1.2, for which the information part of its own packet of information received from the calling subscriber station A (see Fig. 3b) and the "erasing" packet (see Fig. 5c, d) are used. At the same time, using the “zero” packet as the “erasing” packet, the resulting code packet will have the form shown in Fig. 6a and Fig. 8a, and using the “single” packet it will be the form shown in Fig. 6c and Fig. 8c . Then, in the control device 1.4, a single code packet is formed, including the address and information parts (in Fig. 6b and Fig. 8b when using the "zero" packet as an "eraser" and in Fig. 6d, Fig. 8g - when using the "single" ), which, using a radio transmitting device 1.3 _{1, is} transmitted to the called and calling subscriber stations A and B via a common direct communication channel. The volume of a single code packet is strictly fixed and does not exceed the volume of its own packet of information generated at the calling subscriber station A: V _BS ≤V _A.

After reception by radio receivers 2.2 ₁ , 2.2 _{2 of a} single code packet (see Fig. 6b, 8b) in the allocation blocks 2.4 ₁ , 2.4 ₂ , the address part of the single code packet and the code packet are extracted from the single code packet. Then, in the allocation blocks 2.2 ₁ , 2.2 ₂ , the information part of the correspondent’s own information package is extracted from the code packet. This selection is carried out using the information part of its own package of information stored in storage units 2.3 ₁ , 2.3 ₂ . At the same time, a “erasing” packet is allocated at the calling subscriber station A (see FIGS. 5c, d), which indicates the absence of its own information packet from the correspondent. At the called subscriber station B, in the allocation block 2.4 ₂ , the information part of the correspondent’s own information packet is extracted from the code packet using the “erasing” packet stored in the storage block 2.3 ₂ in the absence of generating its own information packet on the called subscriber station B (see FIG. 5 B). Then, at the calling and called subscriber stations A and B, the information part of their own information packet is erased, for which purpose the information part of the next own information packet generated at this station can be recorded in storage unit 2.3 _{1 of the} subscriber station A, and in storage block 2.3 ₂ be recorded "zero" or "single" packet (see figv, d).

 After that, at the calling subscriber station A, the next own information packets are formed and all of the above actions are repeated until the transfer of their own information packets from the calling subscriber station A to the called subscriber station B.

The formation of the code packet in the conversion unit 1.2 of the base station 1 and the allocation of the information part of the correspondent's own information packet in the allocation blocks 2.4 ₁ , 2.4 _{2 of the} called and calling subscriber stations 2 ₁ , 2 ₂ can be performed in various ways. In particular, in the first embodiment, for the formation of a code packet in the conversion unit 1.2, the informational parts of the own information packets from the corresponding subscriber stations are multiplied modulo two, and to extract the informational part of the correspondent's own information packet in the allocation blocks 2.4 ₁ , 2.4 _{2 of the} calling and called subscriber stations A and B, the code packet is multiplied element-wise modulo two with the previously stored information part of its own information packet.

Below is an example of the formation of a code packet in the conversion unit 1.2 of the base station 1 and the allocation of the information part of its own correspondent information packet in the allocation blocks 2.4 ₁ , 2.4 _{2 of the} calling and called subscriber stations A and B in the first embodiment. The following binary sequence is conventionally accepted as the information part of the own information packet of information generated at the calling subscriber station A: 11001 (see Fig. 3b), and the binary sequence 01100 is used as the information part of the own information packet of information generated at the called subscriber station B (01100 ( see figg). The code packet generated in the conversion unit 1.2 by elementwise multiplication modulo two elements of the information parts of its own information packets has the following form: 10101 (see figa).

 In a one-way transmission of information, for example, from the calling subscriber station A to the called subscriber station B in the conversion unit 1.2 of the base station 1, the code packet in the first embodiment will be generated by modulo multiplying two elements of the information part of its own information packet received from the calling subscriber station A and erasing package. Fig. 6a shows a code packet, and Fig. 6b shows a single code packet corresponding to it, obtained using the "zero" erasing packet (see Fig. 5c), and Fig. 6c, g shows a code packet and its corresponding single a code packet obtained using a “single” erasing packet (see FIG. 5 d).

To extract the information part of the correspondent’s own information packet produced in the allocation unit 2.4 _{1 of the} calling subscriber station A, the code packet received from the base station 1 (see Fig. 4a) and the information part of the own information packet stored in the storage block 2.3 will be used ₁ (see figb). In this case, the information part of the correspondent’s own information package will be highlighted (see Fig. 5b). At the called subscriber station B, a code packet (see Fig. 4a) received from the base station and the information part of the own information packet stored in the storage unit 2.3 ₂ will be used to extract the information part of the correspondent’s own information packet (see Fig. 3d). At the same time, in the allocation block 2.4 ₂ , the information part of the correspondent’s own information package, shown in Fig. 5a, will be received.

In the second embodiment, for conversion in the conversion unit 1.2 of the information parts of the own information packets from the corresponding subscriber stations into a code packet, they are added element by element. In this case, the code packet element is assigned the value “unit” at E ₁ = E ₂ and the value “zero” at E ₁ ≠ E ₂ , where E ₁ and E ₂ are the values of the corresponding elements in the stacked pair of elements of the information parts of their own information packets generated on calling and called subscriber stations. To extract the information part of the correspondent’s own information package from the code packet in the allocation blocks 2.4 ₁ , 2.4 _{2 of the} calling and called subscriber stations A and B, the code packet is added element-wise with the information part of the own information packet previously stored in the storage unit 2.3 ₁ , 2.3 ₂ . In this case, the element of the highlighted information part of the correspondent’s own information package is assigned the value “unit” at E ₃ = E ₄ and the value “zero” at E ₃ ≠ E ₄ , where E ₃ and E ₄ are the values of the corresponding elements in the stacked pair of elements of the code packet and previously memorized information part of its own package.

Below is an example of the formation of a code packet in the conversion unit 1.2 of the base station 1 and the allocation of the information part of its own correspondent information packet in the allocation blocks 2.4 ₁ , 2.4 _{2 of the} calling and called subscriber stations A and B in the second embodiment. The following binary sequence is conventionally accepted as the information part of the own information packet of information generated at the calling subscriber station A: 11001 (see Fig. 3b), and the binary sequence 01100 is used as the information part of the own information packet of information generated at the called subscriber station B (01100 ( see figg). For the elementwise addition according to the indicated rule, which is performed in the conversion unit 1.2 of the base station 1, the informational parts of own information packets received from the corresponding subscriber stations A and B will be used (see Fig. 3b, d). The resulting code packet will look like: 01010 (see Fig. 7a).

 In the case of one-way transmission of information, for example, from the calling station A to the called station B in the conversion unit 1.2 of the base station 1, the code packet in the second embodiment will be generated by adding, according to the mentioned rule, the elements of the information part of the own information packet received from the calling subscriber station A and the erasing packet . On figa shows a code packet, and on figb corresponding to a single code packet obtained using the "zero" erasing packet (see figv), and figv, d - code packet and its corresponding single code a packet obtained using a “single” erasing packet (see FIG. 5d).

To extract the information part of the correspondent's own information packet produced in the allocation unit 2.4 _{1 of the} calling subscriber station A, the code packet of the single code packet received from the base station (see Fig. 7a) and the information part of the information packet of its own stored in the storage block 2.3 will be used ₁ (see figb). In this case, the information part of the correspondent’s own information package will be obtained (see Fig. 5a). At the called subscriber station B, a code packet (see Fig. 7a) and an information part of its own information packet stored in the storage unit 2.3 ₂ (see Fig. 3d) will be used to extract the information part of its correspondent information packet. In this case, the information part of the correspondent’s own information package, shown in FIG. 5b, will be obtained.

 In principle, other methods of generating a code packet at the base station can be implemented with the subsequent allocation of the information part of the correspondent’s own information packet at the calling and called subscriber stations.

 Thus, the exchange of messages in digital mobile radio networks with packet information between two subscribers located in the service area of one base station is carried out using three communication channels instead of four. This leads to an increase in the degree of their use and, as a result, to an increase in the throughput of the mobile communication system.
