What Is Open Business?

A service is a communication capability provided by a telecommunications administration or service provider to meet the user's communication needs. As far as the telephone service is concerned, the telephone network provides users with call connections to realize the ability for users to make calls. To provide users with call capabilities is to provide users with telephone services. However, the "commodity" of such a telephone service is only manifested when a call is made between users.

With the development of society, especially the gradual establishment of a market economy, in order to participate in market competition, various enterprises and groups have put forward higher requirements for communications, requiring constant updates like commodities, and adding new functions to make them more suitable for users . In terms of telephone services, this means providing new telephone services to users. The so-called new telephone service is to add some performance that meets user requirements on the basis of basic telephone services, or a telephone service with some characteristics. For example, the called centralized payment service, which is currently familiar to the public, means that when a user dials a specific number to talk to the other party, the cost of the call is paid by the other party (called party). The feature of this service is that the cost of the call is paid by the called party. Because the characteristics of the telephone service can be reflected from various aspects, many new telephone services will appear. However, compared with the basic telephone service, these new telephone services only add some service features or characteristics to the basic telephone service, so the new telephone service is a telephone supplementary service.

Any new telephone service is a supplementary service, which has its own business characteristics. It reflects the most basic business unit that users feel when they use the service. This basic business unit is called a service feature, and it also represents the ability of the network to provide services to users. Therefore, a business is composed of one or more business characteristics. In addition, you can choose other business features you need to enhance a business.

Intelligent network open service classification

In order to enable the network to rapidly develop new services to meet user needs and occupy the service market, the telecommunication network must be further developed so that the realized services are not directly related to the network. A set of functional module structures are introduced on the basis of the existing telephone network to form Intelligent network based on SCP. According to ITU-T Q.1200 series recommendations, INCS-1 specifies 25 IN target services and 38 IN target services.

From the perspective of 25 target services and 38 target service characteristics, some IN services only need to include one service characteristic, such as call forwarding (CF), mass calling (MAS) and other services. Some may require several service features. For example, the called centralized payment service must have one number (ONE) and reverse charging (REVC) service features.

The services that a telecommunications network can provide to users can be divided into two categories, one is called Basic Service, and the other is Supplementary Service.

Basic services include Bearer Service and Teleservice.

The bearer service is the service capability that the network between the user and the network interface can bear.

The user terminal service range is from TE (terminal equipment) to TE, such as telephones, smart user telegrams, video teletext, and so on.

The supplementary service is a service provided to users after enhancing certain performance on the basis of basic services. At present, on the telephone network, the ability of digital program-controlled switches is used to open some supplementary services to users, such as abbreviated dialing and hotline services.

The supplementary services supported by the intelligent network make full use of the intelligence of the network. In addition to the supplementary services that can be provided on the PSTN or ISDN, the intelligent network can also provide more powerful supplementary services such as PCS (personal communication service) , AFPH (Advanced Called Pay Service), etc.

Intelligent Network Open Service Example of Intelligent Network Open Service

The following introduces several intelligent network services that have been standardized in China. Before introducing, first explain the business users and service providers: Service Subscriber refers to the user who applies for this service to the service provider; Service Provider refers to the Business departments, such as telecommunications operations.

Intelligent network open service called centralized payment service

Meaning

This service is a new telephone service reflected in billing performance. Its main feature is that the call to the service user is paid for by the called party, while the calling party does not pay for the call. For example, when a business, enterprise department, or individual applies as a business user to open the service, the telephone cost of the call to the business user is paid by the business user. Because these calls are free to callers, they are often called toll-free calls.

Business characteristics

This service has the following features in addition to the features of the service user to pay for the call:

a. One Number

It means that when a business user has multiple public network phone numbers, he can only register a unique called centrally paid phone number. Calls to this phone number can be routed to different destinations according to the requirements of the business user. . For example, calls can be routed to different destinations based on the originating area of the call.

b. Call Forwarding on Busy / No Reply

When the destination number of the call is busy or there is no answer, the call can be forwarded to another number or several numbers specified by the service user. At present, the service user can register up to two forward numbers. Forward shared these two forward numbers. For each call of a service user, the number of forwards is limited to two.

c. Call Barring

That is, the service user can be limited to calls made by users in some areas and block calls from other areas; or users in some areas are not allowed to make calls to him and only calls from other areas are allowed. Business users can register up to 10 restricted (used) numbers.

d. Voice prompt (Voice Prompt)

It is to prompt the caller who uses this service, request the user to follow the prompts for further operations, or send a recording notification to the user to notify a certain situation.

e. Selecting a destination by time (Routing by time)

It means that the business user can choose the destination number for his incoming calls at different times, such as holidays, weeks, or hours. The minimum unit is minutes. Currently, it is set to four time periods, that is, the user can register up to four time periods and Four destination numbers corresponding to these four time periods.

f. Password access (PIN Access)

That is, the service user can require the calling user to call a centralized pay service of the called party, and the password must be dialed in to connect. The password is four digits.

g. Select destination by calling location (Routing by Caller Location)

That is, calls to business users can be routed according to the geographic location of the calling user.

h. Call distribution

It means that a service user can allocate calls to it to different destination numbers in a certain proportion.

i. Simultaneous Call Limit

It means that when the number of simultaneous calls to a certain destination of a business user reaches a certain limit, it will not be connected and a recording notification will be sent to the user.

j. Call Limit for Calls to 800 Users

It means that the service user can specify the maximum limit of the number of calls or call costs (one of two options) that can be accepted within a period of time (such as one month). The user sends a recording notification.

Intelligent network open service debit card calling service

Meaning

The debit card service allows users to make calls on any telephone (DTMF telephone) and charge the charges to a prescribed account number. Users using debit card services must have a unique personal card number (Card Number). When using this service, the user enters the access code, card number, and password (PIN, Personal Identification Number) as required. After the network confirms the entered card number and password and sends a confirmation instruction to the user, the card holder can dial the called number to make a call like a normal call.

Debit card business can be divided into four categories according to the characteristics of the card (payment method and use method), namely:

Class A users (pay-per-month users). Users who have installed telephones apply for the debit card business, which meets the requirements after being credibly reviewed by the telecommunications department, and can pay the telephone bill monthly based on the telephone bill.

Class B users (pre-paid users). When applying for this service, the user must pay a certain amount of telephone charges in advance, and deduct the call charges once when using it. When the prepaid amount is used up during a call, the system stops providing services, and the user needs to pay the prepayment to continue using the service; if the user has not paid the prepayment after three months, the user card is automatically cancelled. If the user requests to cancel the debit card, the telecommunications department must return the balance of the prepaid in the account to the user.

Class C users (one-time users). By purchasing a valuable debit card, the user can use the service within a specified period of time (such as one year). When the user uses the service, the call cost is deducted once. When the accumulated value of the value card is reached, the system stops providing services.

Class D users (one-time users without passwords). By purchasing a valuable debit card, the user can use the service within a specified period of time (such as one year). When the user uses the service, the call cost is deducted once. When the accumulated value of the value card is reached, the system stops providing services. This type of user does not have a password, while A, B, and C users have a password.

Business characteristics

In addition to recording the cost of the call on the account number of the debit card, this service also features:

a. Destination Restricted Calling

That is, the debit card business can only make calls to certain ranges of destination numbers or cannot make calls to certain ranges of destination numbers. Cardholders can register up to 10 restricted (used) numbers, and restricted (used) numbers can be countries Number, area code, office number, or called number.

b. Limit indication

When the cost of the call on the balance of the B, C, and D cards reaches the minimum one-minute allowable call limit, the user is notified, and the call is terminated when the time limit is reached.

c. Password setting (PIN Set, Personal Indentification Number Set)

It represents a number that can be set by the card holder himself to prevent his / her debit card from being stolen. The password is four characters long.

f. Change password (PIN Modification)

That is, the card user can have the ability to modify the password PIN. Only the card user can modify the password, and the management personnel cannot modify the password, but in certain specific situations, for example, when the card user forgets the password set by himself, the management personnel can cancel the password at the request of the user.

g. Preventing Spoofing (Enhanced Security)

This refers to the inspection of continuous calls. When the card number and password are correct, the number of consecutive calls within a day exceeds a certain cost or number of times (the cost or number of times depends on the user's needs). The card number and password should be rejected and the trial call interrupted. And send a recording notification to the user.

h. Prompt & Collection

That is, the ability to issue a tone or language to the user and collect information from the user.

i. Query balance (Current Credit)

The user dials the corresponding number and performs the operation of checking the balance according to the regulations, and has the ability to provide the user with the query of the balance. Class A users cannot query the balance through the phone. They can only go to the service management department (SMP) to check the total call charge.

j. Abbreviated Dialing

The user can dial fewer digits for the called number, and the length of the abbreviated number is 1 digit, that is, each cardholder can perform abbreviated dialing for 10 users.

k. Modify Abbreviated Dialing Number Modification

The card user can have the ability to modify the abbreviated dialing, that is, the original abbreviated number can be assigned to the new called number.

l. In the process of entering passwords, account numbers or dialing other numbers, if you give up halfway or need to redial, you do not need to hang up. You can press the "*" key. The input is invalid and the system will prompt the user to enter again. .

6 Intelligent Network Open Service (6) Telephone Voting Service

Meaning

This business is a kind of consultation or opinion service provided to the society. Enterprises and institutions that need to conduct public opinion polls can apply to the network for one or more telephone voting numbers as business users to investigate the public's opinions on certain matters through the telephone network. The user who is willing to vote can dial his designated voting number to register his vote according to his choice, or dial a unique voting number. After dialing, he will give his opinion.

The network classifies and counts the number of calls and user opinion information for each voting number. Business users can query their business statistics at any time through terminals and DTMF phones.

Business form

VOT services can take the following forms to meet different needs:

a. Simple VOT

This is the simplest type of electronic voting business, with only voting and no other activities such as lottery. Each VOT number itself represents an opinion. The user only needs to dial a certain number, and the system will automatically count and then play a thank you message to the caller. Voting ends without any other operation.

b. Radio VOT

This VOT is actually a simple VOT business plus a lottery. In this VOT, a VOT number also represents an opinion. The service user can specify certain winning rules (such as the nth call, by percentage or time interval), the system counts the number of calls, and connects the selected call to the service. At the number specified by the user (host), for other unselected calls, the system will count the number and send a thank you message to the caller.

c. Multi-select VOT

This VOT service only has a project code and no opinion code. Therefore, a VOT number represents a project. Specific opinions need to be selected by the user according to the system's language prompt. Business users can apply for a lottery or no lottery.

Business characteristics

a. Regional (accessible office number) restrictions (optional feature)

If business users want their services to be open only in certain regions or offices, when applying for VOT services, they can propose to restrict / allow users' calls according to the long-distance area code or office number of the calling user. The business users can register up to Allowed / restricted numbers.

b. Maximum number of calls (optional feature)

If a service user wishes to limit the maximum number of calls of his own service, when applying for a VOT service, the maximum number of calls can be specified. During the operation of the service, once the number of calls reaches this threshold, the service automatically ends.

c. Validity Period (Basic Features)

When business users apply for VOT business, they must determine the validity period of their business, calculated in weeks.

d. Business Type Selection (Basic Features)

When business users apply for VOT services, they must choose one of the above-mentioned VOT service forms, that is, simple VOT, single-select VOT, and multiple-select VOT.
