Description

The utility model relates to mobile cellular communications and can be implemented using the wireless access protocol (WAP).

Recently, the Internet has been developing rapidly. The World Wide Web is widely used as a standard infrastructure on the basis of which various applications can be hosted. A growing number of people are using the world wide web to solve everyday problems. Something similar is happening in the field of mobile telecommunications, where there is an increasing need for wireless Internet access, in particular with the help of WAP.

Instant messaging services are popular on the Internet. At the same time, interest in the functionality of mobile devices is growing, and the short message service (SMS), outdated for technical reasons, can no longer satisfy all the needs.

Wireless networks entailed the development of wireless Internet, as a result of which a new WAP standard was developed.

The extensible mobile profile hypertext markup language (XHTML Mobile profile), which is also part of WAP, is used to present information from the World Wide Web in the form required for a mobile device.

Currently, Internet subscribers are given the opportunity to exchange instant messages; for this exists

many specialized protocols and programs. For subscribers of cellular networks, Internet models are transferred directly, which makes it possible for subscribers to communicate using programs that adapt the capabilities of a cell phone and cellular network to existing Internet services.

A known system for exchanging text messages between subscribers of a mobile cellular network, comprising at least one base transceiver station with individual addressing, providing two-way coverage of subscribers, and a server containing specialized interactive applications; the system provides transmission of an interactive display message of the RTMP type, reception of response messages of all subscribers, transmission of response messages for displaying information of this interactive application, RU 2292120 C2.

The disadvantage of this system is that it provides a call not to a specific subscriber, but to all subscribers in a given geographical area, which does not allow for personal communication of cellular subscribers.

A known system for exchanging synchronous WAP messages between subscribers using mobile telephony, comprising a WAP chat server configured to create a document for each client containing the client profile and messages sent to them, as well as synchronizing the presentation of these documents on the WAP chat server; the system also includes a mobile phone network SMS center and mobile terminals, US2002078154.

This technical solution was made as a prototype of this utility model.

The disadvantage of this system is the fact that sending a WAP message is possible only to a subscriber registered on a WAP chat server; subscribers who did not install

communication with the WAP chat server, cannot receive messages from other subscribers. In addition, a serious drawback of the system is that the WAP message is transmitted immediately to all subscribers registered on the WAP chat server, communication between only two subscribers is impossible.

The objective of this utility model is to provide the possibility of exchanging WAP messages between the calling and called subscribers of mobile telephony regardless of the registration of the called subscriber on the WAP chat server, as well as ensuring the inaccessibility of these messages to all other subscribers.

According to a utility model, a system for exchanging synchronous WAP messages between subscribers using mobile telephony, comprising a WAP chat server, a mobile phone network SMS center and mobile subscriber terminals configured to wirelessly communicate with a WAP chat server, further comprises a unit for connecting the called subscriber to the WAP chat server, the input of the indicated block is connected to the output of the WAP chat server, and its output is connected to the input of the SMS center of the mobile telephone network.

The applicant has not identified any sources of information containing information about technical solutions that are identical to the claimed utility model, which allows us to conclude that it meets the criterion of "novelty."

The applicant also did not establish sources of information about the influence of the distinguishing features of the utility model on the technical result achieved - the possibility of exchanging synchronous WAP messages between mobile phone subscribers if the called subscriber is not registered on the WAP chat server, while ensuring that these messages are not accessible to all other subscribers.

The essence of the utility model is illustrated in the drawing, which shows a diagram of the system.

A system for exchanging synchronous WAP messages between subscribers

using mobile telephony contains a standard WAP chat server 1, SMS center 2 of the mobile telephone network, unit 3 connecting the called party to the WAP chat server. This unit in a specific example is made in the form of a personal computer 3 and is implemented on the basis of a 65 nm Intel® Core ™ 2 Duo E6850 processor or similar. The functionality required to realize the claimed benefits is provided by using the specified processor.

To implement the claimed functions, standard communication protocols are used:

HTTP (eng. HyperText Transfer Protocol - “Hypertext Transfer Protocol”) is a protocol for the application level of data transfer primarily in the form of text messages. The basis of HTTP is the client-server technology, that is, it is assumed that there are consumers (clients) who initiate the connection and send the request, and suppliers (servers) who wait for the connection to receive the request, perform the necessary actions and return the message with the result. HTTP is currently widely used on the World Wide Web to retrieve information from websites. The protocol is an open standard and its detailed description can be found in open sources: http://ru.wikipedia.org/wiki/HTTP.

In the claimed System, the HTTP protocol is used to send text messages between subscribers in the process of an established communication session. At a lower level - for the connection between the WAP-CHAT server and the WAP gateway of the Mobile Operator.

Short message peer-to-peer protocol (SMPP) - a protocol that describes the interaction of the end client with the SMS server. It is used to send SMS and USSD messages, usually in VAS (Value Added Services - value-added services, additional communication services, which include the proposed System. The protocol is based on the exchange of PDU (protocol data units, packets

protocol data) transmitted at OSI layer 4 (TCP / IP session or X.25 SVC3). PDUs have a binary representation to increase transmission efficiency. Packet exchange can occur both synchronously (after sending a request, further packet exchange is suspended until a response is received), and asynchronously (requests are sent without delay, the processing of responses occurs as they arrive).

The protocol features allow it to be used specifically to establish a connection between subscribers when sending a call to Subscriber B. At a lower level, the protocol is used to connect between the output of unit 3 of the System and the input of the SMS center of a cellular operator.

SMPP is an open standard and its specifications can be found in open sources: http://smsforum.net/.

To transfer data, the standard HTTP GET protocol is used.

For authentication and security, cookies are used.

To establish a connection with the SMS center, use the bind_transmitter command (http://smsforum.net/SMPP_v3_4_Issuel_2.zip).

To send the initiating message, use the submit_sm command (http://smsforum.net/SMPP_v3_4_Issuel_2.zip).

The input of block 3 is connected to the output of the WAP chat server 1, and its output is connected to the input of the SMS center 2 of the mobile telephone network.

The system operates as follows.

The caller of the mobile telephone network who wishes to exchange synchronous WAP messages with other subscribers of the mobile telephone network using mobile telephone communication is registered on the WAP chat server. After that, the caller using a standard WAP browser installed on his mobile

terminal 4, enters the WAP chat server 1, which, using a standard application, identifies it by the subscriber number of the mobile terminal 4. An additional password can be entered for the above identification. The caller receives this password, if he wishes, when registering on the WAP chat server. The subscriber is registered on the server with the obligatory use of block 3 using the HTTP protocol and cookie functions, which ensures the necessary level of confidentiality achieved by transferring subscriber authentication tools (login and password for entering the server) only to the registered subscriber. Server 1 after successful identification of the calling subscriber creates by standard means a document containing the profile of the calling subscriber, and forms a space for communication - a page on which there is a field called subscriber. Then, the calling subscriber enters the number of the mobile terminal 5 of the called subscriber in the called subscriber field, and makes his call. The call is made through block 3 using the SMPP protocol and the submit_sm function, which performs the function of generating an initiating message, converting this message into a format understandable to the SMS center and sending the message directly. In this call, the called subscriber is sent a message generated and converted for sending by block 3, for example, in the WAP or SMS format, which initiates the connection of the called subscriber to the WAP chat server via a mobile telephone channel. Block 3 also provides guaranteed delivery of the message to the called subscriber on the mobile terminal 5, and ensures delivery to the subscriber with the entered number, thereby ensuring the personality and confidentiality of communication between the called and calling subscribers. When an initiating SMS message is received, the called subscriber opens a link to connect to the WAP chat server,

contained in the incoming initiating SMS message. When a message is generated, block 3 ensures the uniqueness of the received link, access to which is possible only for the called subscriber, thereby achieving the practical impossibility of connecting another subscriber to the dialogue between the called and calling subscribers and ensuring the necessary confidentiality of communication. Upon receipt of the initiating message in the WAP format, the browser of the mobile terminal 5 of the called subscriber establishes, with his consent, communication with the WAP chat server. After this, synchronous WAP messages are exchanged between the calling and called subscribers. At the time of sending a WAP message, it is displayed simultaneously in both subscribers. This ensures the creation of a communication space accessible only to the calling and called subscribers.

To implement the utility model, well-known technical means with standard applications are used, which determines, according to the applicant, compliance with its criterion of "industrial applicability". Block 3 is based on a 65 nm Intel® Core ™ 2 Duo E6850 processor or equivalent.
