Description

Multi-speech prompting method for intelligent network

The present invention relates to a kind of method that in telecommunications network, in IN service, realizes multi-speech prompting with Intellight network mode.

In existing intelligent network business, the process that is absolutely necessary of the information interaction between system and the user, it also is a big characteristic of our intelligent network business simultaneously.In the process of system and user interactions, system provides relevant information to be very important to the user.In order to finish function to user's play cuing information, stipulated between SCP (Service Control Point) and the SSP (Service Switch Point) in China INAP (the Intelligent Network Application Protocol) rules, between SCP and the IP (Intelligent Peripheral), the operating structure between SSP and the SRF (Specialized ResourceFunction).The wherein relevant sign that relates in the warning tone operation professional voice of playing.Yet rules do not provide other description to the method for voice identifier except the parametric description of explanation voice identifier with 4 bytes.

Because the INAP rules had not both been stipulated the voice coding of miscellaneous service at present, did not provide concrete coding method yet, existing switch device all identifies voice with the numeral without any coding rule to various voice, thereby causes following problem:

1. owing to the encoded radio of each professional voice is not made unified regulation as the signal tone of switch, the switch device of each producer and intelligent equipment also have nothing in common with each other to the coding that same voice content provides, and coding does not have the implication on the attribute.So just be unfavorable for the interconnected of each producer's equipment, run counter to the original intention of INAP development;

2. when service needed during by certain language form of different voice of playback played in order or multilingual type voice, traditional method then is to send a plurality of operations in order to tone playing equipment.In realization, the transmission of a plurality of operations then is to send message by network or serial ports between each module, and a large amount of operations sends the transmission load of be bound to emphasizer and serial ports, causes system performance to descend;

3. because the INAP rules do not have the regulation of specific object to present voice coding, cause by data base querying voice resource and Managing speech resource difficulty relatively, efficient is very low.

If therefore the sign to voice does not adopt any coding rule, and only identify voice resource in the miscellaneous service with one 32 voice identifier sign indicating number (messageID), then sign will be any one numerical value in from 0x00000000 to 0xFFFFFFFF.This scheme does not have the bit field about business description, make the difficulty of searching and manage very of voice, and owing to lack about playback languages and playback description bit field in proper order, cause when service needed during by certain language form of different voice of playback played in order or multilingual type voice, will be by the transmit operation respectively of each languages, increase communication load, caused system performance to descend.In order to address this problem, Shenzhen Huawei Tech Co Ltd. once proposed a kind of scheme that voice identifier is numbered.This scheme has been enriched the information representation ability of messageID, has improved professional voice coding efficient, has improved the service efficiency of speech data inquiry and Internet resources.In order to compare, below this scheme is simply introduced with the present invention:

The kind of the voice coding of this scheme comprises warning tone coding and recording encoder.Wherein warning tone coding be used between SCP and IP, SCP and SSP, SSP and mailbox, IP and the mailbox alternately, be divided into a plurality of bit fields in 32 codings and identify voice content and various attribute (service numbers, languages number, languages, languages playing sequence, the business unit of holding, professional voice sequence number).Recording encoder is used for mutual between SMS (Service Management System business management system) and IP (ip intelligent peripherals), SMS and SSP (Service Switching Point), SMS and the mailbox, is divided into a plurality of bit fields in 32 codings and identifies the have particular community voice of (service numbers, languages, the business unit of holding, professional voice sequence number).

Its coded format is as follows respectively:

One) warning tone coded format

The warning tone coded format is encoded with four bytes, can comprise 4 kinds of different languages and playback order in the coding.

Table one

8bit	10bit	5bit	9bit
				The operation code bit field	4 kinds of language order coding bit fields	Business is sponsored subscriber-coded bit field	The voice coding bit field

31 23 13 8 0

In the last table, the label of below is an item, wherein being described as follows of each territory:

1, operation code: different business is corresponding to different operation codes, and the operation code scope is 0--254, and for the warning tone coding that can be used for a plurality of business, the operation code value is FF.The coding that SCE is different to all traffic assignments of its generation, in SCE passes to the management logic file of SMS, comprise this operation code and this business whether with sponsor user related information.Be 255 to the traffic limits that can generate among the SCE like this.

2,4 kinds of language order codings: coded format is as follows.It is the warning tone that 0 and 1,0 expression does not have this language that each languages has or not yard value, and 1 expression has the warning tone of this language.Each languages sequence code value can be 01,10,11,00, respectively gets a value by mandarin, English, dialect in these four kinds of code values, thereby determines the sequence code of other language, and default value is 01.Its form is as follows:

Table two

1bit	2bit	1bit	2bit	1bit	2bit	1bit
							Mandarin has or not a yard bit field	Mandarin sequence code bit field	English has or not a yard bit field	English sequence code bit field	Local language has or not a yard bit field	Local language sequence code bit field	Other language has or not a yard bit field

23 21 20 18 17 15 14 13

Business is sponsored subscriber-coded: have nothing to do if this business of professional voice is sponsored the user, its value is 00000.If business therewith business to sponsor the user relevant, for being generated by SCE with the coding of sponsoring the irrelevant part of user, its value is 00000: for being generated by SMS with sponsoring user-dependent coding, value is not 00000.

The voice coding bit field: if business therewith business to sponsor the user irrelevant, this voice coding is generated by SCE.If business therewith business to sponsor the user relevant, for being generated by SCE with the coding of sponsoring the irrelevant part of user: for stipulating coding range with the coding of sponsoring user's relevant portion by SCE (Service CreateEnvironment), specific coding is generated in this scope by SMS.

With the typical warning tone coding of such scheme as:

0xABa000CD: the Chinese of the CD voice of expression AB business.

0xABb800CD: Chinese, the English of the CD voice of expression AB business, the Chinese back is English earlier.

0xABd400CD: Chinese, the English of the CD voice of expression AB business, English earlier back Chinese.

Two) recording encoder form

The recording encoder form: encode with four bytes, do not comprise the playback order of different languages in the coding, only explanation is that a kind of language in coding.

Table three

8bit	1bit	1bit	1bit	1bit	6bit	5bit	9bit
								Operation code	Mandarin has or not sign indicating number	English has or not sign indicating number	Local language has or not sign indicating number	Other languages have or not sign indicating number	Need not	Business is sponsored subscriber-coded	Voice coding

31 23 22 21 20 19 13 8 0

Wherein operation code and voice coding are encoded with warning tone.4 kinds of languages coding is only with 4, gets 0 or 1 languages of representing this recording encoder with every.Can only have one in these four is 1.The recording encoder scheme should be consistent with the scheme of warning tone coding.

Exemplary audio records coding as:

The Chinese speech file recording encoder of the CD voice of 0xAB8000CD:AB business.

The English voice document recording encoder of the CD voice of 0xAB4000CD:AB business.

This locality language voice document recording encoder of the CD voice of 0xAB2000CD:AB business.

Other language voice document recording encoder of the CD voice of 0xAB1000CD:AB business.

We can find from top elaboration, and such scheme has solved the said standard in front, efficient and managerial problem really, have satisfied intelligent network product demand at home substantially.But along with the development of intelligent network technology, along with the expansion of intelligent network product market abroad, this encoding scheme can not satisfy overseas user's requirement, and its major defect has the following aspects:

1. professional relevant with voice.At present in the intelligent network business generative process, the information of languages is write direct in the executable file, promptly professional relevant with this service informing language form.So, when our service application to other country, when the type of service informing language changes, professionally just need regenerate, test and load, can't satisfy a plurality of countries to same business but the requirement of different language types;

2. the voice language form of Zhi Chiing is few.Maximum can only be supported four kinds of language forms in the voice coding at present, be respectively: mandarin, English, the local dialect and do not belong to a kind of language of above-mentioned languages require to support multilingual support situations such as Swahili, Spanish, French, Portuguese to meet the demands for the overseas customer;

3. the voice suggestion playing sequence is specified dumb.In present voice identifier encoding scheme, the playing sequence of mandarin, English and the local dialect can be specified flexibly, but, for other languages that do not belong to above-mentioned three kinds of language, the order of its broadcast can only be in the back of above-mentioned three kinds of languages, this is the country of mother tongue for overseas non-Chinese, non-English, just can't satisfy the requirement on the speech play order;

4. can't satisfy the requirement of many currency types price data speech play.In intelligent network business, system often needs to play the special data type Notes of Key Data to the user, such as the remaining sum on the subscriber card.In existing speech coding system, the unit of currency, the position of monetary unit are that for example in Chinese, the unit of currency is " unit " along with the type of language changes, and monetary unit is to play at the rear portion of numeral.Because monetary unit is by the type decided of language, has the remaining sum of what US dollars just can't carry out if want to play the user so in Chinese, therefore need to expand existing price and play scheme, when the broadcast price with on the information of monetary unit;

Purpose of the present invention is exactly in order to overcome the above problems, and a kind of multi-speech prompting method for intelligent network is provided, and it has been realized that support is more multilingual, used purpose more flexibly by new voice identifier encoding scheme.

For achieving the above object, the present invention proposes a kind of multi-speech prompting method for intelligent network, be used for determining the broadcast mode of voice, it is characterized in that comprising the steps: 1) voice identifier of voice that needs are play encodes, contain one " species index " district in the coding, determine one " species index number " with each value in this district; 2) one " species index table " is set, lists the attribute of each possible " species index number " pairing voice in above-mentioned " species index " district in the table, the attribute of described voice comprises broadcast mode; Described " species index table " loaded by the backstage and is set among the SSP, also can dynamically be filled in by SCP, and the property store of described voice is to SSP; 3) in the time need playing to concrete voice, read " species index number " in " species index " district, SSP described by searching " species index table ", attribute according to these corresponding voice of " species index number " described in " species index table ", determine the broadcast mode of these voice, and play this voice according to determined broadcast mode.

Owing to adopted above scheme, not that attribute with voice directly writes in the voice identifier sign indicating number, but only in the voice identifier sign indicating number, write a call number, the attribute of voice is determined with a concordance list in addition, the position that so just can save the voice identifier sign indicating number greatly is long, and the attribute kind that enables to support increases greatly.As: be used under the condition of multilingual broadcast,, can only supporting four kinds of language (four languages) with former method, but can support 258 kinds of language with our rule as determining voice attributes with 8 bit code length.On the other hand, because after adopting this method, voice attributes itself is not in the write-in program, but be present in the concordance list, like this when needs are revised, just needn't update routine, and it is just passable only to need concordance list is made amendment, and has strengthened its adaptability and dirigibility greatly.

Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.

Embodiment one: the multi-speech prompting method for intelligent network in this example is the playing sequence that described method is used for classification and each languages of definite languages under the situation of multilingual broadcast, comprising the steps: 1) voice identifier of voice that needs are play encodes, contain " operation code " district in the coding, " category of language index " district and " voice coding " district, determine one " category of language index number " with each value in " category of language index " district: one " category of language concordance list " 2) is set, list the attribute of each possible pairing voice of index number in above-mentioned " category of language index " district in the table, comprise the languages categorical measure, languages numbering and playing sequence; 3) in the time need playing to each concrete voice, read the index number in its " category of language index area ", then by searching " category of language concordance list ", attribute according to these voice in " category of language concordance list ", determine the broadcast mode of these voice, comprising: the languages that should play and the playing sequence of each languages.

The present invention optimizes the design of encoding scheme can also support existing voice identifier coding method, simultaneously, by the mode of parameter configuration, supports a kind of encoding scheme of new voice identifier.New encoding scheme is supported 256 kinds of language classifications at most, supports 8 kinds of language simultaneously at most.Its form is as follows:

Table four

8bit	8bit	16bit
			Operation code	The category of language index	Voice coding

In this scheme, the implication of " operation code " is consistent with existing definition, and " voice coding " equals existing " business is sponsored subscriber-coded "+" voice coding ", and " category of language index " is then corresponding to existing " 4 kinds of language order codings ".For with the CNS compatibility, length is decided to be 8 bit (as not considering typical problem, obviously its length can be decided to be other values, can support more combination as length when longer, length reduces then can save word bit number).Because the 8bit finite capacity, can not hold the type and the playback order of 8 kinds of language, therefore with its index as sound-type and playback order, concrete language form and playback order are tabled look-up by index and are obtained.The index of 8 bit has 256 kinds of combinations, can satisfy the needs of professional voice.For the messageID compatibility to old form, the language form of old form and playback order also are provided with in this table, with the compatibility of certain skill realization to old messageID form.

Category of language indexed format such as table five:

Format	The category of language index
			8bit
Old form	4 kinds of voice and in proper order preceding 8bit
			8bit

In this table, preceding 8 of " 4 kinds voice and order " of old form also are set up, because the special rules of coding, " 4 kinds voice and order " preceding 8 bit can unique expression speech category and voice order.Like this, no matter the messageID that sends of SCP is new coded format or old coded format, and SSP is all according to the processing of tabling look-up of this table.Realized compatibility to two kinds of coded formats.

Table six

		0b1111101010，ob1001101010，0xfa，0x9a	Dialect, English, mandarin

Table seven is category of language index tableau formats of SSP side.

The category of language index	Language classification number	The language classification
			0～255	1～8	Language classification 1
		Language classification 2
					Language classification 3
		Language classification 4
					Language classification 5
		Language classification 6
					Language classification 7
		Language classification 8

But the final election of language classification, the playback order of every kind of language is determined successively.The particular content of this table need be determined according to concrete demand.Simultaneously old " 4 kinds voice and order " corresponding codes (seeing the above table) will be reserved out, be used for supporting the support to old messageID form coding, and new messageID form coding also can use this index.The benefit of doing like this is that SSP, SCP etc. all need not do special sign for the problem of compatibility and distinguish the messageID form, can unify to handle.

The language classification that the backstage is determined and selected other playback of class of languages are set to the foreground with following data structure in proper order and handle.

Table eight

8bit	8bit	8bit	·····	8bit
					The category of language index	Language classification number	Language classification 1	·····	Language classification 8

The speech category index is represented with 8 bit, index range 0～255, and 8 bit of voice class number represent other number of class of languages of this index playback, represent 1～8 language classification of this index correspondence with 8 bit.The language classification is represented with 8 bit, supports 256 kinds of voice at most.Language classification in the table represents that the multipotency of playback successively puts 8 kinds of voice, and these 8 kinds of voice are chosen from 256 kinds of voice.

Xia Mian structure for example:

Table nine

0	8	1	3	5	8	9	10	11	25 3
										1	3	1	3	5	7	9	25 5	25 5	25 5

Expression:

8 kinds of voice play in playback index 0, and the order of playback is language classification 1,3,5,8,9,10,11,253 successively.

3 kinds of voice play in playback index 1, and the order of playback is language classification 1,3,5 successively.Because the playback number is 3 kinds, just not playback such as language classification 7,9.

Such scheme can be realized following 2 points at least:

1, to the support of voice language form quantity

The enforcement of above-mentioned encoding scheme from 4 kinds of language forms of original support, is supported 4 kinds of voice to play simultaneously and has been become the most nearly 256 kinds of language forms of support, supports 8 kinds of voice to play simultaneously, has solved the problem that the multilingual number of types is supported effectively.

2, to supports professional and concrete sound language form relevant issues

After adopting new encoding scheme, what business was filled in the process of processed voice is not the concrete syntax type and the playing sequence of voice, but the category of language index of voice (this index also can dynamically be filled in by SCP), and the quantity of the voice of this index correspondence, the type of language and playing sequence are by the category of language concordance list translation that is stored on the SSP, thereby can be under not revising professional prerequisite by revising on the SSP quantity of the language of respective index correspondence in the category of language concordance list, the mode of language form and order satisfies different user to multilingual demand, thereby has solved the professional and concrete relevant problem of suggestion voice language form.

Embodiment two: to the support of many currency types more voice price data playback problem

In the Intelligent Network Application Protocol of ITU-T, price (Pice) is an OCTET STRING (SIZE (4)) according to type, is binary-coded decimal in CINAP, if with the such Price Range of binary representation, only need 27 bit, so Sheng Xia several bit just can be used for representing the type of currency.Therefore, it is feasible currency type information being joined in the coding of Price data type, both can satisfy the standard of ITU_T, can represent the information of multiple currency type again, and can realize the configurable purpose of currency type.

Be head it off, described method can be used for the multi-speech prompting under many currency types, multilingual situation, to determine classification, the rule of combination of monetary unit and the used languages of pronouncing of Currency Type, comprising the steps: 1) voice identifier of voice that needs are play encodes, contain " Currency Type index " district and " price numerical value " district in the coding, determine one " Currency Type index number " with each value in " Currency Type index " district; 2) one " Currency Type concordance list " is set, lists the attribute of each possible pairing voice of index number in above-mentioned " Currency Type index " district in the table, comprise the rule of combination of pronounce languages, Currency Type and monetary unit; 3) in the time need playing to each concrete voice, read the index number in its " Currency Type index area ", then by searching " Currency Type concordance list ", attribute according to these voice in " Currency Type concordance list ", determine the broadcast mode of these voice, comprising: the rule of combination of the Currency Type that should play, languages and each monetary unit.

Specifically, in the new Multiple Currencies support scheme of this kind, adopted following coding method:

Table ten

4bit	28bit
		The Currency Type index area	Price numerical value district

The 4bit of Currency Type index area is used for representing the currency type of price numerical value, and maximum can be supported 16 kinds of currency types.Price numerical value district then adopts 16 systems to represent concrete price value, the minimum unit representation of its value.The maximum numerical value that can reach more than 200,000,000.

For example: price numerical value is 1234.56, and language form is Chinese, and monetary unit is " unit ", and the Currency Type index of Chinese " unit " is 1, and the value in the price price that then issues should be: 1001E240 Currency Type concordance list form:

Table ten one

Languages	Currency Type	Rule of combination
			Chinese	Renminbi	A+ circle+B+ angle+C+ branch+D+E
Chinese	Dollar	A+ dollar+BC+ cent+D+E
			Chinese	Other coin
English	Renminbi
				。。

Rule of combination ABCD refers to a kind of zone bit in the table, and as representing A with 0xFF, 0xFE represents B, and 0xFD represents C, 0xFC represents D, and 0xFB represents E, and whether the D back wants fraction part to put together with one, and promptly together whether BC, the Chinese fraction part has the angle branch, and dollar does not just have, and has only cent.E represents the sequencing of the unit of broadcast and numeral, and if any E, unit is play in expression earlier, plays numeral again.

Other is as circle, and the angle is divided, dollar, U.S. grading information is a MsgID, represents this voice.
