technical field

The invention relates to the field of intelligent network technology, in particular to a voice playing method and system supporting multiple currencies, a service control point (SCP) and an intelligent peripheral (IP). the

Background technique

The intelligent network technology system mainly includes functional entities such as Service Control Point (SCP, Service Control Point), Service Switching Point (SSP, Service Switching Point), and Intelligent Peripheral (IP, Intelligent Peripheral). SCP is the core component of the intelligent network, which stores user data and business logic. The main function of the SCP is to start different service logics according to the call events reported by the SSP, and send call control instructions to the corresponding SSP according to the service logic, so as to realize various intelligent calls. The SSP provides the call connection function. The SSP can detect the intelligent call request and establish a control relationship with the SCP; it responds to the instructions of the SCP and allows the service logic in the SCP to affect the call processing. IP is a special resource to assist in the completion of intelligent services, and usually has various voice functions, such as voice synthesis, playing recorded notifications, receiving dual-tone multi-frequency dialing, voice recognition, and so on. the

In intelligent business, SCP often not only interacts with SSP, but also needs to interact with IP to realize human-computer interaction between business processes and users, play voice prompts to users and collect user information. IP may be integrated in SSP, or may Independent of SSP, the SSP that integrates IP is called integrated SSP/IP, and the IP that is independent of SSP and is a single device is called independent IP. The SCP first requests the SSP to connect the current call to the IP device, and then sends an instruction to the IP to request to play a notification sound to the current caller or to play a notification sound and collect user information. the

In the intelligent network service, the service interacts with users through IP equipment, plays notification sounds to users and collects user information. Play voice prompts (PA, Play Announcement), voice prompts and collect user information ( PC, Prompt And Collect User Information), Voice Prompt and Receive Message (PR, Prompt And Receive Message) The definition of Price in the Variable Part (VariablePart) parameter only defines the price value field, and does not define the corresponding Price Currency type. In the actual business operation process, different users of the same business may have accounts in different currencies, and because the VariablePart parameter only defines the price value field for the Price definition, and does not define the currency type corresponding to the Price, the IP system can only use A default currency is used to play voice prompts, which cannot meet the actual needs of business operations. the

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. the

Embodiment 1: Set currency type variable tone parameters, the intelligent peripheral (IP) receives the playback operation instruction from the service control point (SCP), extracts currency type information and amount information from the playback operation instruction, and performs voice Synthesis, play the amount prompt sound containing the currency type. the

Example 1: A new amount and currency type (priceAndCurrencyType) field is added to include both variable amount information and currency type information. the

The following uses the INAP protocol and the CAP protocol as examples for description. In order to meet the needs of multiple currencies in the actual operation of the business, it is necessary to modify and expand the variable part (VariablePart) parameter in the playback operation instruction on the basis of the original standard specification, and add an amount and currency type (priceAndCurrencyType) field. The Amount and Currency Type fields include current currency type information and amount information. According to actual operation needs, the above playback operation instructions include the operation of playing voice prompts (PA, Play Announcement), voice prompts and collecting user information (PC, Prompt AndCollect User Information) or voice prompts and receiving messages (PR, Prompt AndReceive Message) , or any combination of the three. the

For the CAP protocol, the modification of this embodiment is defined as the modification of the standard:

VariablePart::＝CHOICE{

integer [0]Integer4,

number [1]Digits, --Generic digits

time [2]OCTET STRING(SIZE(2)), --HH:MM, BCD coded

date [3]OCTET STRING(SIZE(4)), --YYYYMMDD, BCD

Coded

price [4]OCTET STRING(SIZE(4))

priceAndCurrencyType[31]OCTET STRING(SIZE(5))

}

The definition of PriceAndCurrencyType is shown in Table 1:

Table 1

It can be seen from the above description that under VariablePan, a new priceAndCurrencyType field is added, which contains current currency type information and amount information. If the SCP sends the priceAndCurrencyType field to the IP, the IP can directly extract the currency type and amount information from the received message. the

For the INAP protocol, modify as follows:

VariablePart ::＝CHOICE{

integer [0]Integer4,

number [1]Digits, --Generic digits

time [2]OCTET STRING(SIZE(2)), --HH:MM, BCD coded

date [3]OCTET STRING(SIZE(3)), --YYMMDD, BCD coded

price [4]OCTET STRING(SIZE(4)), --BCD coded

priceAndCurrencyType[31]OCTET STRING(SIZE(5))

}

The definition of PriceAndCurrencyType is shown in Table 2:

Table 2

Similar to the CAP protocol, under VariablePart, a new priceAndCurrencyType field is added, which contains current currency type information and amount information. If the SCP sends the priceAndCurrencyType field to the IP, the IP can directly extract the currency type and amount information from the received message. the

For the network cable intelligent network mobile application part (WIN MAP) protocol, the modification is as follows:

The play operation indication is carried by a dedicated resource function indication (SRFDIR) operation. Because the SRFDIR operation includes two types of announcement modes: one is the announcement mode indicated by the voice list parameter (AnnouncementList), and the other is the announcement mode defined by the execution script (ExecuteScript). Since the voice list mode cannot support variable voice playback, the script mode is used to play variable voice. The ExecuteScript parameter definition defined by WIN MAP related specifications is shown in Table 3:

table 3

The name (ScriptName) and script execution control (ScriptArgument) parameters of the script are not clearly defined in the existing specification, but the maximum byte length is given as 96 bytes. Changing the value of ScriptArgument can change the voice played. Here, the format of defining ScriptArgument in this example is shown in Table 4:

Table 4

The format of the fixed part is shown in Table 5:

table 5

The PriceAndCurrencyType field has been added, so that there are 7 variable pronunciation types:

Number Number 1

Integer Integer 2

Date Date Date 3

Time Time 4

Amount Price Price 5

Duration Duration 6

Amount with currency PriceAndCurrencyType 254

The definition of PriceAndCurrencyType is shown in Table 6: when playing the amount including currency, the variable tone part is 9-byte octets. the

Table 6

It can be seen from the above description that a new type of variable sound is added, that is, the priceAndCurrencyType field, which contains current currency type information and amount information. If the SCP sends the priceAndCurrencyType field to the IP, the IP can directly extract the currency type and amount information from the received message. the

Example 2: Modify the existing amount parameter to include variable amount information and currency type information. the

It can be realized by modifying the PA and VariablePart parameters in the PC operation defined by the INAP/CAP specification or the bit meanings of some fields of the Price sub-parameter of the sub-parameter ScriptArgument in the ExecuteSrcipt parameter defined by the WIN MAP specification. the

For example, the variable part parameters defined by the CAP specification are as follows:

VariablePart::＝CHOICE{

integer [0]Integer4,

number [1] Digits, --Generic digits

time [2]OCTET STRING(SIZE(2)), --HH:MM,BCD coded

date [3]OCTET STRING(SIZE(4)), --YYYYMMDD, BCD coded

price [4]OCTET STRING(SIZE(4))

}

The structure of the existing price is shown in Table 7:

Table 7

--bits HGFE DCBA -- tens of thousands hundreds of thousands -- Hundreds thousands -- 0～9 Tens -- Hundredths Tenths

Here, bits E to H of the first byte of price can be used as the currency type. The modified price structure is shown in Table 8:

Table 8

--bits HGFE DCBA 1 Currency Type(0～F) PriceElement(HEX) 2 PriceElement(HEX) PriceElement(HEX) 3 PriceElement(HEX) PriceElement(HEX) 4 PriceElement(HEX) PriceElement(HEX)

There are many ways of modification, and the above only provides an example of modification, but is not limited to the above modification example. the

For the WIN MAP specification, it can be implemented by modifying the Price sub-parameter of ScriptArgument. The principle is the same as the implementation of the CAP protocol, and will not be described again. the

Example 3: Add or modify existing parameters to include currency type information. the

For example, there are many parameters in operations such as PA and PC, and many parameters are composite parameter types. In this way, a currency type parameter can be added to other parameters of PA and PC. , for example, add a currency type parameter parallel to variableParts in the existing variable message (variableMessage) parameter; or, it can also modify the structure of an existing parameter, similar to modifying the price structure in Example 2, for example The existing elementary message ID (elementary message ID) in PA and PC can be modified to carry the currency type. In this way, the newly added or modified existing parameters and the existing amount parameters include currency type information and amount information respectively. the

In short, in Embodiment 1, as long as the announcement operation instruction includes currency type information and amount information, this application does not limit how to set the currency type information and amount information in the announcement operation instruction. the

Referring to Fig. 2, it is a schematic flow diagram of playing the amount prompt tone including the currency type based on the WIN MAP protocol according to Embodiment 1 of the present invention. the

Steps 201-205, SSP sends ORREQ (OriginationRequest) message to SCP, SCP sends SEIZERES (SeizeResource) message to SSP, SSP returns response seizeres to SCP; SCP sends CONNRES (ConnectResource) message to SSP, SSP according to the received request and IP A temporary connection is established between them, after which IP sends an INSERQ (InstructionRequest) message to SCP. All the above steps are exactly the same as the existing processing. the

In step 206, the SCP sends a SRFDIR (SRFDirective) message to the IP, and the message includes currency type information and amount information. the

Step 207, the IP extracts currency type information and amount information from the received instruction, performs speech synthesis, and plays an amount prompt tone including the currency type. the

In step 208, the IP returns a response srfdir to the SCP. the

In steps 209-210, the SCP returns a response instreq to the IP, and returns a response orreq to the SSP. the

So far, the amount prompt tone including the currency type has been played. the
