How to cancel the value-added service fee?

You can directly dial 10086, press the 0 key, perform manual service, and then you can cancel related services. What are the mobile value-added services? Voice service is the most basic service in mobile communication service, so other services relative to voice service are generally called value-added services. At present, the value-added service that people often mention is to develop and operate services other than basic services such as voice on the mobile communication network. At present, mobile value-added services are generally divided into three categories, namely, mobile intelligent services, mobile data services and mobile IP services.

2. 1 mobile voice value-added services

IN terms of mobile voice value-added services, Intelligent Network (IN) is the mainstream technology to provide voice value-added services. Intelligent network is a layer of service network superimposed on the original communication network, and it is a framework for generating and realizing various new services quickly, conveniently, economically, flexibly and effectively. Intelligent network can be used in many telecommunication fields. Intelligent network based on GSM network is called mobile intelligent network, and intelligent network based on CDMA network is called wireless intelligent network.

The currently published specifications are divided into three stages: the first stage, the prepaid stage and the second stage. The main services supported in the first stage include incoming call screening service, caller name display service and voice control service; Prepayment stage mainly supports prepaid services; The second stage supports five services, such as called centralized payment and instant payment.

The mobile voice value-added services successfully launched on the mobile/wireless intelligent network include: prepaid service, mobile virtual private network (VPMN) service, M-zone service, mobile IP telephone service, wireless advertising service, mobile calling and called payment service, home number service, mobile voice mail service, mobile secretary service and color ring back tone service.

2.2 Mobile data value-added services

According to the user experience and implementation technology, the next generation of mobile data value-added services will include mobile content services, mobile commerce services, mobile location services, mobile terminal services, etc., as detailed below.

Mobile content service

Mobile content service refers to the content information service that mobile users can browse or subscribe in various ways, and it is an extension of the Internet in the mobile field. The access modes available to mobile users include SMS, MMS, WAP, BREW, etc. The content includes weather, news, stock market, mail, chat and other information. Third-party content providers are responsible for providing content and operators are responsible for providing access.

Mobile commerce

Mobile commerce refers to the business of trading through mobile devices. Mobile services include micropayment, mobile banking, mobile securities and mobile insurance.

To develop mobile services, we must solve several key problems, such as security, reputation and payment methods. Mobile commerce uses a closed mobile communication system to conduct transactions, and its security and reliability are much higher than that of the open Internet. . Mobile commerce takes reputable mobile operators as payment intermediaries, which solves the problem of reputation crisis; Mobile commerce allows voice, SMS, WAP and other payment and transaction methods, which is more convenient and flexible.

Mobile location service

Mobile location service is a service that provides location information for mobile users. Mobile location services include public safety services, location-based billing, tracking services, enhanced call routing, location-based information services and enhanced network services.

Mobile terminal service

The mobile terminal service is a service that runs by using the processing power of the mobile terminal. This service regards the mobile network as a transparent data pipeline, and directly downloads applications from the Internet server and runs them on the terminal. Mobile terminal services include JAVA service, SIM card toolkit service (SAT) and various MExE applications that can be downloaded and run on PDA and PDA.

3 Next Generation Mobile Value-added Service Network

3. 1 network architecture

The field of mobile communication is divided into three levels: mobile communication basic network, mobile value-added service system and management operation and maintenance support system. The mobile communication infrastructure network provides basic communication services; The mobile value-added service system provides various mobile voice value-added services and mobile data value-added services, and provides an open service interface for value-added services; Management operation and maintenance support system provides unified management and operation and maintenance support functions.

3.2 Mobile Value-added Service System

The mobile value-added service system includes: mobile voice value-added service subsystem, mobile packet data value-added service subsystem, mobile commerce subsystem, mobile location service subsystem, mobile multimedia resource subsystem and mobile message service subsystem. The functions of each subsystem and the interfaces with internal and external entities are described as follows:

Mobile voice value-added service subsystem

It evolved from the existing mobile intelligent network SCP of CAMEL2 and the wireless intelligent network SCP of WIN. This subsystem is the operating platform of mobile voice value-added services, which can provide various voice value-added services based on GSM and WCDMA networks. The subsystem will support the circuit-switched part of CAMEL3 protocol, as well as the circuit-switched parts of WIN stage 1, WIN PPC and WIN stage2 protocols.

Mobile packet data value-added service subsystem

Mainly the newly-built CAMEL3 mobile intelligent network SCP. The subsystem supports the packet switching part of CAMEL3 protocol, and can provide various mobile packet data value-added services based on GPRS network, such as GPRS prepaid, GPRS VPN, real-time charging of streaming media, etc. In terms of external interface, the subsystem interacts with SGSN which realizes gprsSSF function through CAP, and with HLR through MAP protocol. In the future, this subsystem will be combined with OSA to realize data session control SCF.

Mobile commerce subsystem

It evolved from the existing mobile micropayment platform (MPP). This subsystem has two functions. First, operators, as the operating platform of carrier-level mobile commerce services, provide mobile commerce services themselves; Second, as a mobile commerce gateway, it provides an open interface for mobile commerce SP.

The subsystem will provide various payment methods, including prepaid account, post-paid account, micropayment account, virtual wallet, bank card, bank account and so on. Provide a variety of access methods, including voice, SMS, MMS, WAP, etc. Provide standard and open service access interface; Provide a reliable security mechanism and use the security authentication management mechanism based on PKI system to realize the mobile phone security authentication based on the third-party CA; Provide a variety of account management functions, including account opening, account closing, freezing, unfreezing, cash deposit and withdrawal, transfer and so on. Provide all kinds of account processing, including account rolling, account reconciliation, account generation and settlement. It can provide various mobile commerce services, such as micropayment, mobile banking, mobile securities and air ticket booking.

Mobile location service subsystem

It can be evolved from the existing CAMEL2 mobile intelligent network SCP, and can also be built as needed. This subsystem can be used as the operation platform and location service gateway of carrier-level mobile location service.

The subsystem will support various positioning technologies, including chief operating officer, electronic OTD, TOA, global positioning system and so on.
