DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication message conversion method for converting a message by linguistic processing in transmitting and receiving a message in a communication system, and more particularly, to describing a conversion processing method in a simple language. The present invention relates to a communication message conversion method and a communication message conversion device that handle this simple program as CPU software data.

[0002]

2. Description of the Related Art A message is translated in a conventional communication system by sequentially comparing and verifying a received message with a message configuration specified by a communication protocol.
This was done by converting it to the corresponding information. Therefore,
In order to convert the information into meaningful information (character information, etc.) that can be understood by humans, the bit pattern of the message to be communicated is analyzed (translated) by computer software. The translation process had to be described. Therefore, whenever the message specification (configuration) is changed, the software for analyzing (translating) the bit pattern of the message is modified or recreated each time.

FIG. 10 is a block diagram showing an outline of a communication system to which such a conventional communication message conversion method is applied. In the figure, 1 is a wireless unit as a communication unit,
2 is an antenna, 3 is a baseband processing unit, 4 is a communication control unit, 5 is a personal computer, 6 is a speaker / microphone, 7 is a CPU of the communication control unit 4, 8 is an input buffer, 9 is a message conversion program, 10 Is an output buffer.

Next, the operation will be described. Radio waves from the network are received by the antenna 2 and sent to the radio unit 1 to be demodulated into electric signals. The demodulated electric signal is sent from the radio unit 1 to the baseband processing unit 3, converted into a baseband signal, and input to the input buffer 8 of the communication control unit 4. The message based on the input baseband signal is converted into a human-readable everyday language under the control of the CPU 7 using the message conversion program 9 and output to the personal computer 5 from the output buffer 10. In the case of an audio signal or the like, it is output to the speaker / microphone 6.

FIG. 11 is an explanatory diagram showing the structure of a received message. In the figure, 21 is a plurality of protocols (two of # 1 and # 2 are shown), and 22 is a message in a daily language format. Input buffer 8 of communication control unit 4
The message stored in the CPU 7 is translated by the message conversion program 9 in the CPU 7. Here, the message includes a protocol type, a message type,
It has a specific data pattern part that represents an information element. A computer program for analyzing this is created, and the sequential processing is performed as follows.

First, a translation system to be processed is determined according to a protocol type. In general, a communication system includes a plurality of protocols (communication procedures). Although the protocol type is unique in one communication system, the message type and the information element type are defined independently for each protocol, and therefore overlap the message type and the information element type of other protocols. there is a possibility. Therefore, it is common to separate the translation system for each protocol type. Here, the protocol type is defined for each provided service type such as circuit-switched call connection management, packet-switched call connection management, mobility management, and radio resource management. Protocol 21 (#
As a result of performing the message conversion of 1), an output of the message 22 in the everyday language format is obtained.

There are a plurality of message types in one protocol, and the message type is one information unit (a command or function as a unit for specifying an operation) for transmitting information. For example, a call control protocol for making a telephone call is "SET" for call establishment.
It has an "UP message" and a "REL message" for disconnecting a call. One information unit (telegram) is 1
One message type has no more than one message type. The information element is an element constituting the message, such as a parameter 1 for specifying the content of the operation. One message has zero or more information elements. This message may have a plurality of information elements, and the information elements may be commonly used in two or more messages.

FIG. 12 is a flowchart showing the flow of a message conversion process by the communication control unit 4. The message includes a plurality of information elements, and each information element is coded according to a format defined by a protocol type. The flowchart shown in FIG. 12 is created for each protocol type. Here, a flowchart for protocol type 1 corresponding to protocol 21 (# 1) is shown.

First, in step ST11, a message type is determined. As a result, if the message identifier indicating the message type is “M11” indicating the message 1, the process proceeds to step ST12, where a11 of the information element 1
The process of b11, the process of c11, and the process of d11 are performed, and further, in step ST13, the process of a12 and the process of b12 of the information element 2 are performed. If the message identifier indicating the message type is “M12” indicating the message 2, the processing of a13 of the information element 2 and the processing of b13 are performed in step ST14, and the processing of a14 of the information element 2 is performed in step ST15. The processing of b14 and the processing of c14 are performed.

When converting a message according to the protocol 21 (# 2), a flowchart for the protocol type 2 corresponding to the protocol 21 is selected.
The same processing as described above is performed.

Next, a method for assigning meanings to information elements will be described with reference to FIG. In the method of assigning the meaning of the information element, in addition to the case where the information element as shown in FIG. In some cases, the correspondence is made via a certain linear algebraic transformation as shown in FIG. The information element is not limited to a fixed length but may be a variable length. When the information element length is a variable length, the expression method may be a case where an extension bit is provided to indicate the presence of the next data, an information element indicating the data length is provided, or a special symbol ( Special data indicating the end of data) may be provided.

The physical allocation of the information element to the real memory is not limited to a byte (8 bits) unit but may be an allocation of less than 8 bits. Also, there may be an assignment that extends over a plurality of bytes.

[0013]

Since the conventional communication message conversion method is configured as described above, when converting a received message into a character string or the like, software is created for each communication protocol (format). However, there is a problem in that the software size increases, and when adding functions or changing specifications, a large amount of work is required to remodel the software, which takes a long time.

[0014] The present invention has been made to solve the above-described problems.

The reason why the simplified language has such a format is as follows.・ Being easy to program. Be easy to understand.
(Basically, all specifications can be expressed by substitution formulas.)-High processing speed. (The range of variables is limited. The stack is fixed.)

FIG. 2 is an explanatory diagram showing the structure of a message according to the first embodiment. In the figure, 3
Reference numeral 1 denotes a protocol having a plurality of messages (messages 1 to 5 in the illustrated example) each having a specific data pattern portion representing a protocol type, a message type, and an information element. The protocol 31 is the protocol of the received current message to be processed. In such a communication system, generally, a plurality of protocols 31 are used.
(Communication procedures) are mixed, but the # 1 protocol is illustrated here. Reference numeral 32 denotes a message in a daily language format converted by the communication control unit 4 from the message of the # 1 protocol 31.

There are a plurality of message types in the protocol 31, and the message type is one information unit (a command or a function as a unit for specifying an operation) for transmitting information. For example, a call control protocol for making a telephone call is "SE" for call establishment.
Examples are a "T UP message" and a "REL message" for disconnecting a call. One information unit (message) is composed of one message type, and one message does not have two or more message types. The information element is an element constituting a message, and corresponds to a parameter 1 or the like for specifying the content of the operation. One message has zero or more information elements. This message may have a plurality of information elements, and the information elements may be commonly used in two or more messages.

Reference numeral 33 denotes a message list prepared for each protocol 31 by using an address table having each message and a corresponding message address as elements. Reference numeral 34 denotes a message list prepared for each message and translated for each information element. It is an information element table based on an address table having information element rules for processing and information element rule addresses corresponding thereto. Reference numeral 35 denotes a simple program which holds the program source of each information element conversion program, which is addressed by the information element table 34.

The above-mentioned protocol type is defined for each type of service provided, such as circuit-switched call connection management, packet-switched call connection management, mobility management, and radio resource management, and is unique to one communication system. It is. On the other hand, since the message type and the information element type are independently defined for each protocol, there is a possibility that the message type and the information element type of other protocols overlap.

FIG. 3 is a flowchart showing the flow of the message conversion process by the communication control unit 4. Protocol 31 held in input buffer 8 of communication control unit 4
Is sent by the CPU 7 to the simple program 11
Is performed.

The feature of the communication message conversion method according to the first embodiment of the present invention is that the flowchart shown in FIG.
It can be used regardless of the message protocol type and message type. The message list 33, the information element table 34, and the simple program 35 in FIG. 2 correspond to data processed by the communication control unit 4 on the flowchart shown in FIG. Therefore, this data (message list 33, information element table 34,
By replacing the contents of the simple program 35),
It is possible to convert messages corresponding to a plurality of protocol types.

Hereinafter, description will be made sequentially according to the flowchart shown in FIG. First, in step ST21, the protocol identifier of the received message is determined. here,
A communication system has a plurality of protocols (message formats) for each function, and each has a message and an information element independently. First, the protocol 31 (# 1) shown in FIG.
Since it is necessary to separate the message for each protocol as in the above, the protocol identifier of the received message is determined in step ST21.

If the result of the determination is that the protocol identifier is valid (if it is an identifier that exists in the protocol), the corresponding message list 33 is selected, and step ST22 is performed.
In, the message list 33 is searched based on the message identifier in the message, and the corresponding message address is extracted. That is, if the message identifier is "M11", the message address of message 1 in the message list 33 is extracted, and if the message identifier is "M12", the message address of message 2 in the message list 33 is extracted.

If the message address search is successful, the process proceeds to step ST23, where the type of the information element is determined, and the corresponding information element table 34 is searched.
At T24, an information element conversion program describing a conversion method of the information element is called from the simple program 35 indicated by the information element rule address. That is, if the message identifier is “M11” and the identifier of the information element is “E11”, the information element 1 rule address is extracted from the information element table 34 of the message 1 and the conversion method of the information element 1 of the simple program 35 is performed. Is called based on the address. If the message identifier is “M11” and the identifier of the information element is “E12”, the rule address of the information element 2 is extracted from the information element table 34 of the message 1 and the conversion method of the information element 2 of the simple program 35 is performed. Is called based on the address.

All the information element rule addresses of the information elements constituting the message are written in the information element table 34 shown in FIG. 2 for each message. In addition, since the information element may be used in common by a plurality of messages, the program source of the information element conversion program describing the processing in the actual simple program 35 is the message list 33 and the information element table 34. Are configured independently and the method of associating the components of the message with the actual processing (simple program 35) by the information element rule address of the information element table 34 is adopted.

When the information element conversion program is called from the simple program 35, in step ST25,
The relevant information element is translated according to the rules specified in the information element conversion program. That is, when the information element 1 conversion program is called, the processing of a11, the processing of b11, the processing of c11, and the processing of d11 in the information element 1 corresponding thereto are sequentially executed.

When the process of translating the information element (for example, information element 1) in step ST25 is completed, the management pointer of the information element rule address is updated to the management pointer of the next information element rule address, and the process proceeds to step ST2.
Return to 3. Here, the management pointer indicates a reading point of the original message according to the # 1 protocol 31 stored in the input buffer 8 and a writing point of the conversion result.

Hereinafter, the information element conversion program is called from the simple program 35 in the same processing procedure as described above, and the translation processing is executed according to the information element conversion program. Here, when the information element 2 conversion program is called, in step ST25, the processing of a12 and the processing of b12 in the information element 2 corresponding thereto are sequentially executed. If the extraction of the message address by searching the message list 33 fails, the process returns to step ST23 assuming that the information element does not exist, and the next information element is searched.

This series of processing is repeated until all the information elements have been converted. When the conversion process of all information elements is completed and there is no new information element, and it is determined in step ST23 that there is no search element, the process proceeds to step ST27 and ends the message conversion process.

If the translation process in steps ST23 to ST25 succeeds, a message 32 in a daily language format shown in FIG. 2 is output as a result of the conversion. If the translation process fails, if the information element is a required information element, the entire message is invalidated and the process is terminated. The essential information element is an information element that must be included in a message, and without that information, the purpose of sending the message is lost. On the other hand, if the information element is not required information,
Assuming that the information element did not exist (ignored), the process returns to step ST23, and proceeds to the processing of the next information element.

In the message conversion system method according to the first embodiment configured as described above, the protocol 31
When changing or exchanging the information, the message list 33 corresponding to the protocol configuration of the protocol 31 shown in FIG. 2, the information element table 34 storing the information element rule addresses for each message, and the information element rule addresses are used. What is necessary is just to replace the contents of the simple program 35 for analyzing the information elements with those based on the new protocol configuration. At this time, there is no need to change the flowchart shown in FIG. 3 for performing those processes.

As described above, according to the first embodiment, a simple language for message conversion is defined, and a message address, an information element rule address, and an information element conversion program are defined as a part of the simple language. Define
The simple program described in the simple language is treated as the processing data of the CPU software to execute the restored message analysis process and convert the message, so that the message list 33, which depends on the message, Information element table 34, simple program 3
By exchanging the contents of No. 5, an effect is obtained that a communication message conversion method capable of converting messages corresponding to various protocol types can be realized irrespective of a protocol difference.

Embodiment 2 In the first embodiment, a message list holding a message address of each message, an information element table holding an information element rule address for each message, and a simple program holding an information element conversion program for each information element However, the information element program address of each information element may be stored in the information element list, and the information element conversion program of each information element may be stored in the information element table. FIG. 4 is an explanatory diagram showing a message configuration in such a communication message conversion method according to the second embodiment of the present invention.

In FIG. 4, 31 is a protocol (# 1 protocol), 32 is a message in a daily language format,
The parts corresponding to those in the first embodiment shown in FIG. Reference numeral 36 denotes an information element list based on an address table indicating information element program addresses of the respective information elements. Reference numeral 37 denotes a simple program source prepared for each information element and addressed by the address table of the information element list 36. 3 is an information element table in which an information element conversion program is stored. In the simple program 35 used in the first embodiment, each information element conversion program is based on an information element table 37 by a simple program source.
Is not necessary in this case.

Next, the operation will be described. Here, FIG.
9 is a flowchart showing the flow of a message conversion process according to the second embodiment. Hereinafter, the message conversion procedure will be sequentially described with reference to the flowchart shown in FIG. First, in step ST31, the protocol identifier of the received message is determined. Here, the communication system has a plurality of protocols (message formats) for each function, and each has a message and an information element independently. Therefore, the protocol 31 (#
Since the message needs to be separated for each protocol as in 1), first, the protocol identifier of the received message is determined in step ST31.

As a result of the determination, if the protocol identifier is valid, the information element list 36 corresponding to the message corresponding to the protocol configuration of the protocol 31 is selected in step ST32. Next, in step ST33, the identifier of the information element in the message is searched from the information element list 36, and the corresponding information element program address is extracted. That is, if the identifier of the information element in the message 1 of the # 1 protocol 31 is “E11”, the information element program address of the information element 1 is extracted from the information element list 36, and the identifier of the information element is “E12”. If there is, the information element program address of the information element 2 is extracted from the information element list 36.

If the search for the information element program address is successful, in step ST34, a simple program of the information element conversion program describing the information element conversion method is described from the information element table 37 pointed to by the extracted information element program address. Call the source. That is, from the information element table 37 specified by the information element program address of the information element 1, the simple program source of the information element 1 conversion program is called, and the information element table 37 specified by the information element program address of the information element 2 is called. , A simple program source of the information element 2 conversion program is called.

When the information element translation process in step ST34 is completed, the management pointer of the information element rule address is updated to the management pointer of the next information element rule address, and the process returns to step ST33. Hereinafter, the information element conversion program is called from the simple program 35 in the same processing procedure as described above, and the translation processing is executed according to the information element conversion program. If the extraction of the message address by searching the message list 33 fails, the process returns to step ST33 assuming that the information element does not exist, and the next information element is searched.

This series of processing is repeated until the conversion of all information elements is completed. When the conversion process of all information elements is completed and there is no new information element, and it is determined in step ST33 that there is no search element, the process proceeds to step ST36 to end the message conversion process.

If the translation process in steps ST33 and ST34 succeeds, a message 32 in a daily language format shown in FIG. 4 is output as the result of the conversion. Also,
If the translation process fails, if the information element is a required information element, the entire message is invalidated and the process ends. On the other hand, if the information element is not the essential information, the process returns to step ST33 assuming that the information element did not exist (ignored) and proceeds to the processing of the next information element.

In the communication message conversion method according to the second embodiment configured as described above, when the protocol 31 is changed or replaced, an information element list for each message corresponding to the protocol configuration of the protocol 31 shown in FIG. 36 and the contents of the simple program source of the information element conversion program for the information element analysis in the information element table 37 corresponding to the information element rule address may be replaced with a new protocol configuration. At this time, there is no need to change the flowchart shown in FIG. 5 for performing those processes.

As described above, according to the second embodiment,
A simple language for message conversion is defined, an information element conversion program address and an information element conversion program are defined as a part of the simple language, and the simple program described in this simple language is processed by the CPU software. By replacing the contents of the information element list and the information element table that depend on the message, the message can be converted regardless of the protocol, and the message conversion process is simplified. As a result, effects such as faster processing and smaller software size can be obtained.

It is an encoding table. 43 is a coding table 42
For example, “0: OFF”,
This is a conversion table of a simple program in which conversion rules of the original message 41 such as “1: ON” are described. Reference numeral 44 denotes a conversion message converted by executing a simple program using the conversion table 43. Note that FIG. 6 shows that the original message 41 of “1” has been converted into the conversion message 44 of “ON”.

Next, the operation will be described. When the data conversion process is started, first, in step ST41,
The information (conversion table address) on the conversion table 43 is acquired based on the input coding table 42. Next, the process proceeds to step ST42, where it is determined whether or not the input data of the original message 41 is within the normal range. If not, the process is terminated as it is. on the other hand,
If it is within the normal range, the process proceeds to step ST43, where the code of the original message 41 is normalized, and then the process proceeds to step S43.
At T44, the conversion table 43 specified by the address
Is used to convert the data of the original message 41,
The obtained conversion message 44 is output. When the output of the conversion message 44 ends, the process proceeds to step ST45, where the pointer setting of the message is updated, and a series of processing ends.

As described above, according to the third embodiment,
