Description

The invention relates to systems for transmitting and reproducing SMS messages over a mobile communication network, in particular, to protocols for interacting systems of content providers with an aggregator, and can be used for packet transmission of SMS messages using the TLV protocol.

There is a known method of providing non-voice Premium Rate services to mobile SPS mobile subscribers, which includes the following steps: a) using the SPS network to transmit the request and service; b) transmitting the subscriber’s request to the service provider to request the service; c) issuing the requested service to the subscriber; d) charging the requested service at the price stated by the service provider, separately from the standard tariffs of the operators of ATP networks, while services are also provided to subscribers of ATP networks of other Operators with which the Operator has concluded a Rome agreement, and additionally use a system containing a unit for analyzing subscriber requests, with the help of which they receive and initial analyze requests, the main unit of service logic, which identifies the service, converts the subscriber request into the format of the service provider and controls the provision of the service, the charging unit, by which the service is charged, data is generated containing at least the service request code, the time of the service and the telephone number of the subscriber, the request is generated by keyboard input from a mobile terminal, moreover, they select a request format that is interpreted by the SPS network as either dialing a voice number or transmitting a text fragment to a specific external application (RF patent No. 2336654, IPC H04M 15/00, publ. 10/20/2008).

The closest is the way the end client interacts with the SMS server (SMSC) for sending SMS and USSD messages using the Short message peer-to-peer protocol (SMPP) protocol. The method is based on the exchange of protocol data units (PDUs) transmitted on OSI layer 4 (TCP / IP sessions or X.25 SVC3). PDUs have a binary representation to increase transmission efficiency. Packet exchange can occur as synchronously, i.e. after sending the request, further packet exchange is suspended until a response is received, asynchronously, i.e. requests are sent without delay, processing of responses occurs as they arrive.

A well-known method of interaction between the end client and the SMS server (SMSC) using the SMPP protocol is an open standard and its description can be found in open sources: http://smsforum.net/.

The disadvantage of this method is that the transmission is carried out only at the level of single SMS-messages. In this case, each message must be confirmed by the remote side.

This means that if the content provider sends 500 SMS messages, then the content provider must generate 500 unique protocol messages (PDU-Protocol Data Unit). The remote side must accept them, process them, generate a unique acknowledgment for each PDU and send all acknowledgments. At the same time, the content provider separately processes all the unique confirmations in order to find out which PDUs the remote side of the confirmation did not send to, and there is a possibility of data loss and duplication.

All this creates a high load on the software module that is engaged in servicing the SMPP channel, because of which the method does not provide message transfer rates in the SMPP protocol of more than 400 SMS messages per second.

Another disadvantage of the known method using the SMPP protocol is that each operator has its own different extensions of SMPP, therefore, the minimum necessary set of different specific values is formed, first of all, the data type in SMS messages. All aggregators will support these values in a unified manner and independently engage in the correct mapping of the specialized protocol into their own subset of SMPP.

The technical problem to which the claimed invention is directed is to provide high performance when interacting with an aggregator when sending a large number of SMS messages over a mobile communication network, as well as the reliability and security of sending and receiving SMS message packets.

The stated technical problem is solved by the fact that in the method of interaction of the content provider system with the aggregator for batch transmission of SMS messages, which consists in the formation, transmission of a message and the receipt of a response confirmation message, according to the claimed invention, a package of SMS messages is formed and an SMS packet is transmitted messages using the TLV protocol, where the TLV protocol (Tag, Length, Value) is a way of binary representation of an information block in the form of three fields: information block identifier (Tag), which th is unique and allows you to uniquely determine what data is contained in the information block, values (Value) - the binary representation of the information block, values (Length) - the number of bytes in the Value field, a packet of outgoing SMS messages is formed in the block of the content provider, assigned to it a unique identifier, a sending address and a receiving address, and deliver to the aggregator block, repeating it until a response message is received from the aggregator block that confirms delivery and contains the sending address, the receiving address and a unique and received message identifier, an outgoing message with an SMS message package intended for a subscriber is sent to the operator unit from the aggregator unit, an SMS message delivery report for the subscriber is generated and sent to the aggregator unit in the operator unit, upon receipt of a response confirmation message from the operator unit to Aggregator block generates a response message to the operator in the form of a notification of receiving a report on the delivery of SMS messages to the subscriber and simultaneously generates and transmits a message from the result to the block to the content provider In order to send the package of outgoing SMS messages to the operator, which is assigned a unique identifier, the sending address and the receiving address, the transmission is carried out until the delivery of this message is confirmed by the content provider in the form of a notification on the receipt of the package with the results of the delivery of SMS messages to the subscriber, which contains the corresponding unique identifier messages with the results of sending the operator a package of outgoing SMS messages to transfer incoming SMS messages from the SMS center subscriber to the content provider block in the aggregator block form a package of incoming SMS messages from subscribers, assign a unique identifier, send address and receive address to the message in the form of a package of SMS messages and deliver to the block of the content provider, repeat the delivery until the receipt is confirmed by the content provider in the form of a response message containing same unique identifier.

In addition, in the block of the content provider, a package of outgoing SMS messages is formed in the form of an “outgoing_package” message, a “outgoing_package” message is assigned a unique identifier, a send address and a receive address, they are delivered to the aggregator block before receiving a response message about the packet received from the aggregator block outgoing SMS messages in the form of an outgoing_package_ack message containing a sending address, a receiving address and a unique identifier for a received outgoing_package message.

In addition, an outgoing message is sent from the aggregator block to the operator block by an SMS message package intended for the subscriber in the form of a submit_sm request; in the operator block, an SMS message delivery report for the subscriber is sent and sent to the aggregator block in the form of a submit_sm_resp message .

In addition, in the aggregator block, a message is generated and sent to the block to the content provider with the results of sending the package of outgoing SMS messages to the operator in the form of "send_result_package", which is assigned a unique identifier, a sending address and a receiving address, the transmission is carried out until the delivery of this message is confirmed by the content provider in the form of a notification of receipt of a package with the results of the delivery of SMS messages to the subscriber in the form of a message "send_result_package_ack", which contains the corresponding unique identifier of the message "send_result_package".

In addition, in the operator’s block, a report on the delivery of SMS messages to the subscriber is generated and sent to the aggregator block in the form of the message “delivery_sm_DR”, after receiving which a response message is generated in the aggregator block in the form of a notification on the receipt of the SMS message delivery report to the subscriber in as the message "delivery_sm_resp_DR".

In addition, in the aggregator block, a message is generated about the results of SMS delivery to the subscriber in the form of a package with the results of the delivery of SMS messages to the subscriber in the form of the message “delivery_receipt_package” containing the sending address, the receiving address and a unique identifier, while the message of the form is repeated from the aggregator block “Delivery_receipt_package” to the content provider block until confirmation of receipt in the form of a message “delivery_receipt_package_ack”, which contains a unique identifier for the corresponding message “delivery_receipt_package”.

In addition, to transfer incoming SMS messages from the SMS center subscriber to the content provider block, an aggregator block forms a package of incoming SMS messages from subscribers in the form of an incommg_package message, assigns a unique identifier, sending address and address to the incoming_package message receive and deliver to the block of the content provider, the delivery is repeated until the receipt of confirmation by the content provider in the form of a response message "incoming_package_ack" containing the same unique identifier.

In addition, they check the operability of the communication channel by generating a “ping” message in the unit of the aggregator or in the block of the content provider, which is periodically sent in the absence of transmission packets to determine the state of the communication channel, and each message “ping” is assigned a unique identifier, and each received message of the ping type sends a response message in the form of ping_ack, which includes a unique identifier from the corresponding request message of the ping type.

The technical result is to increase the transmission speed when sending a large number of SMS messages over a mobile network, due to the fact that many SMS messages are sent in one packet, upon receipt of which the aggregator will process one PDU (Protocol Description Unit) (one protocol message) and send one confirmation, which ensures high performance, reliability and security of sending and receiving SMS message packets.

Terms Used In The Description

Aggregation - the process of combining various elements into a single whole, in particular, for mobile services - the provision of services of different service providers through a single system or platform.

Aggregator - a system that provides an interface with the systems of mobile operators. The main purpose of the system is to provide a gateway that allows you to organize convenient and reliable operation between the transport platform (TP) of content providers and SMS centers of mobile operators to facilitate the process of organizing the delivery of mobile content to its consumers - mobile or fixed-line subscribers

Transport platform (TP) is a content provider system that provides messages to an aggregator. TP establishes a connection to the systems of aggregators, monitors the viability of the connection and restores the connection in the event of a break, provides balancing traffic between aggregators.

KP is a content provider.

The TLV protocol (Tag, Length, Value) is a method of binary presentation of information, in which each significant block of information is represented as a triple of:

- block identifier (Tag), which is unique within the current context, which allows you to uniquely determine what data is contained in this block;

- length of the value (Length) - the number of bytes in the Value field;

- Values are a binary representation of block information, and the exact way to interpret the value depends on the type of information (i.e., on the Tag value).

The Value field in the TLV representation can be:

- an elementary unit value (for example, the string "Hello, world");

- a composite value consisting of a sequence of TLV blocks;

- empty. In this case, the Length is zero and physically the Value field in the TLV block is absent.

Figure 1 shows a block diagram of a software and hardware complex, which provides the implementation of the proposed method of interaction of the content provider system with the aggregator for batch transmission of SMS messages using the TLV protocol. The hardware and software complex contains the content provider block 1 connected by the communication channels, the aggregator block 2 and the SMS operator center block 3 of the mobile operator.

Block 1 of the content provider includes a module 4 for servicing the protocol and the associated block 5 of the database.

Protocol maintenance module 4 performs the functions of generating global unique identifiers for outgoing GUID / UUID message packets, and also checks for the uniqueness of packet identifiers received from the aggregator.

Block 5 of the database (DB) is designed to store information about outgoing message packets GUID / UUID.

Block 2 of the aggregator includes module 6 for interacting with content providers, the associated block 7 of the database on packets of outgoing and incoming SMS messages, module 8 for interacting with mobile operators, the input of which is connected by communication channels to the output of module 6, block 9 operational information databases associated with module 8.

Module 6 for interaction with content providers is designed to support the protocol; generates global unique identifiers for packets with the results of sending SMS messages to the operator (send_result), packets with the results of delivery of messages to subscribers (delivery_receipt) and packets of incoming messages; verifies the uniqueness of packet identifiers received from the content provider.

Block 7 of the database is designed to store information about packets, phones of outgoing and incoming SMS messages, the results of sending SMS messages to the operator, the results of message delivery to subscribers;

Module 8 for interaction with mobile operators supports interaction with operators via SMPP protocol, as well as module 3 for interaction with content providers working with the internal protocol.

Block 9 of the database is designed to store operational information for interaction with the operator.

Block 3 SMS center of the mobile operator includes a module 10, designed to receive, process and route SMS messages.

25 - notification of receipt of the package of incoming messages (incommg_package_ack),

26 - (outgoing) SMS message (submit),

27 - report on receipt of SMS message (submit_ack).

The inventive method is as follows.

In block 1 of the content provider, a packet of 12 outgoing SMS messages is formed in the form of an outgoing_package message for sending to aggregator block 2. A message of the type "outgoing_package" is assigned a unique identifier, a send address, and a receive address. The content provider repeats the delivery of the package of outgoing SMS messages in the form of the message “outgoing_package” to block 2 of the aggregator until the delivery aggregator confirms the delivery of the generated packet of 12 outgoing SMS messages.

Upon receipt of a package of 12 outgoing SMS messages in the form of an outgoing_package message in block 2 of the aggregator, notifications 13 are generated and sent to block 1 to the content provider via communication channels about receiving a package of outgoing SMS messages in the form of an outgoing_package_ack message containing the sending address, receive address and unique identifier of the received message.

Next, from the aggregator block 2, an outgoing message 14 intended for the subscriber is sent to the operator block 3 in the form of a “submit_sm” request. After receiving a report 15 on receiving an outgoing message in the form of a “submit_sm_resp” message from block 3 of the statement, in block 2 of the aggregator, block 16 is generated and transferred to block 1 to the content provider with the results of sending the packet of outgoing SMS messages to the operator in the form of the message “send_result_package”.

In this case, the message “send_result_package” is assigned a unique identifier, a send address and a receive address. The aggregator repeats sending the message "send__result_package" until the delivery is confirmed.

In block 1 of the content provider, in order to confirm receipt of packet 16 with the results of sending SMS messages in the form of a send_result_package message, a notification 17 is generated and sent to block 2 of the aggregator on receipt of a packet with the results of sending outgoing messages to the operator in the form of a send_result_package_ack message (one at a time for each message received in the form of "send_result_package").

For all transfers, the message "send_result_package" corresponds to the same unique identifier.

Next, from block 2 of the aggregator, a message with a package of SMS messages is transmitted to block 3 to the operator in the SMS center.

In block 3, the operators generate and send to block 2 of the aggregator a report 18 on the delivery of an SMS message to the subscriber in the form of a message “delivery_sm_DR”, after receiving which in block 2 of the aggregator they generate a response message in the form of a notification 19 on receipt of a report on the delivery of an SMS message to the subscriber in the form of the message "delivery_sm_resp_DR".

In block 2 of the aggregator, a message is generated about the results of SMS delivery to the subscriber in the form of a packet 20 with the results of the delivery of SMS messages to the subscriber in the form of a message “delivery_receipt_package”, including the sending address, the receiving address and a unique identifier. At the same time, from a block 2 of the aggregator, the delivery of a message of the form “delivery_receipt_package” is repeated to block 1 of the content provider until receipt is confirmed.

In block 1 of the content provider, a notification 21 is generated and sent to block 2 of the aggregator of the receipt of a package with the results of the delivery of SMS messages to the subscriber in the form of the message "delivery_receipt_package_ack" (one for each received message "delivery_receipt_package"). Each message of the form "delivery_receipt_package_ack" contains a unique identifier for the corresponding message "delivery_receipt_package", the sending address and the receiving address. For all repeated shipments, the message "delivery_receipt_package" will retain the same unique identifier.

The aggregator transmits a series of incoming SMS messages from subscribers to the Content Provider in the form of packet 24 “incoming_package”. Each incoming_package message has a unique identifier, a send address and a receive address. The aggregator repeats the delivery of the “incoming_package” message to the Content Provider until the confirmation is received from the Content Provider in the form of message 25 “incoming_package_ack”. For all transfers, the message "incoming_package" corresponds to the same unique identifier.

At the same time, the Aggregator is not responsible for gluing together SMS, which are parts of a long incoming message. Therefore, different parts of one long incoming message can be placed in different "incoming_package".

A specific incoming SMS should be transmitted to the Content Provider in only one message of the type “incommg_package”. If the Aggregator received message 25 “incommg_package_ack” from the content provider, then incoming SMS from the confirmed message 24 “mcoming_package” should no longer appear in new messages “incoming_package”.

Transfer by the Aggregator of incoming SMS messages from the subscriber of the SMS center to the content provider is as follows.

The aggregator receives messages 22 from the SMS center deliver_sm_IN, generates a message packet and transmits a message packet in the form of message 24 “incoming_package” to the Content Provider.

Upon receipt of the “incoming_package” message, the content provider generates and sends to the Aggregator a confirmation in the form of message 23 “incoming_package_ack” (one for each received “incoming_package”). Each incoming_package_ack message is assigned a unique identifier from the corresponding incoming_package message, in addition it includes a send address and a receive address.

Check the operability of the communication channel as follows:

To check the operability of the communication channel by the Aggregator or the Content provider, a “ping” message is generated. It is periodically sent in the absence of transmission packets to determine the status of the communication channel. Each ping message is assigned a unique identifier.

One ping_ack reply is sent to each received ping message. A unique identifier from the corresponding request message of the ping type is included in the ping_ack message.

An example of generating requests and messages using the TLV protocol. TLV (Tag, Length, Value) is a method of binary presentation of information, in which each significant block of information is represented as a triple of:

1. The identifier of the block (Tag). The identifier is unique within the current context, which allows you to uniquely determine what data is contained in this block.

2. Lengths of the value (Length). The number of bytes in the Value field.

3. Values. Binary representation of block information. The exact way to interpret the value depends on the type of information (i.e., on the Tag value). The Value field in the TLV representation can be:

- an elementary unit value (for example, the string "Hello, world");

- a composite value consisting of a sequence of TLV blocks;

- empty. In this case, the Length is zero and physically the Value field in the TLV block is absent.
