Schools use a fee-for-service network. Different schools choose different business models depending on their own network status, funding and operating objectives. The current campus network Authentication & Billing system supports two typical business models: the school self-building model and the PPPoE proxy model. Both models are excellent and vary in terms of their applicability, and schools need to carefully evaluate their choice in relation to their own circumstances.
School self-building model: school self-operation
The school self-building model refers to the building and operation of a network of campuses by schools themselves, Authentication & Billing, which sets out its own fee-paying strategy, manages user accounts, and collects web fees. In this model, schools have full operational autonomy: flexible formulas (back months, traffic, daily etc.) can be designed according to students’ needs, with an autonomous price adjustment, with deep interface with a school ' s cartoon, engineering system, etc., and with students registering for their own use on a mobile phone Portal page, and self-help contributions, reducing manual services. The disadvantage is that schools need to invest in systems, provide personnel for them and cover the costs of system maintenance and upgrading.
Operating process for the school self-construction model
Under the self-built model of the school, students are usually connected to the following: after being connected to the dormitory WiFi, they are reoriented to a campus network certified Portal page; students enter into school numbers and passwords to complete certification (required for registration for the first time and selected a set of meals); system costs are calculated based on the student ' s choice of a package, with students paying fees through a cartoon, micromail, payment of treasures etc.; after contribution is successful, the system provides access to the Internet to students so that they can access it properly; during the Internet, the system records the student ' s online hours and traffic usage in real time, counting them according to the set meal rules; students can search for amounts, renewals, changes and meals via a self-service platform; and the graduation or exit system automatically suspends its account number. The school self-building model also supports the integration of schools’ financial systems and direct access to school accounts from network fees, which facilitates financial management and auditing.
PPOE dialling model: Introduction of operator cooperation
The PPOE proxy model means that schools introduce one or more operators, bind the campus wireless network and operator's mobile phone suite to a set of cellular dishes, with the operator covering part of the cost of building and operating the network. In this model, students’ Internet account numbers are tied on the campus network Authentication & Billing system to the operator's account number, and students are certified by dial-up gateways to BRAS, which initiates a PPPOE dial-up to the operator, and after dialing them is successful, students can access the Internet. The advantages of the PPOPE proxy model are that schools can reduce financial and security pressures, that operators bear the cost of network construction and maintenance, that students ' Internet access costs are tied to mobile phone packages and perceived as cheaper; that the disadvantages are limited autonomy for schools, fee-for-charge strategies and package design require consultation with operators, that user data is in the hands of operators and that schools have less control. This model suits schools with limited funding, that wish to build campus networks quickly or that want to work more closely with operators.
Operating process for the PPoE dialling model
Under the PPOE proxy model, students ' Internet access is different from their own building mode: after a student has been connected to the dormitory WiFi, he/she is redirected to the Portal page for registration on campus network; students enter into school codes and passwords that bind operators' accounts to complete certification; campus network Authentication & Billing system validates students, and PPONE dialling is initiated by the proxy gateway to the operator ' s BraS; and the operator BRAS validates the student ' s operator account number, assigns network addresses and post-line access to the student; The Internet traffic of students is accessed via the operator’s web export and the Internet fees are included in the student’s operator’s mobile phone suite; if a student needs to change or renew his or her package, it is handled through the operator’s channel, with the school side only responsible for account binding and basic certification management. Under the PPOE proxy model, schools are managed with an emphasis on account numbering, certification management and network quality monitoring, with specific billing and charges borne by the operator.
Comparison and selection of the two modes
The self-building model and the PPOE proxy model are excellent, and schools need to take a combination of factors into account in their selection. From the point of operational autonomy, the school self-construction model is fully autonomous, the PPPOE sub-design model needs to be negotiated with operators; from the financial input, the school self-building model requires investment in construction and maintenance costs, and the PPPoE alternative model operator bears most of the cost; from the user experience, the student self-constructural model pays for and provides services through school channels, the students have to experience harmonization, and the PPPOE sub-description model students need to operate part of the business through the operator channel, which may be fragmented; From a data security perspective, the user data for the school self-build model are exclusively in the hands of the school and some PPOE proxy mode data is in the hands of the operator; from the point of view of responsibility, the school self-construction model schools assume full responsibility for carrying the responsibilities of the carrier, the PPoE model operators bear the responsibilities of network export and billing, and the school is responsible for the inside part. Schools should choose their own models according to their financial situation, information base, mobility and operational objectives, and can use different models (e.g. free of charge by the school in the teaching area, and Ppoe charges by the dormitory) with flexible combinations.
Mixed models and future trends
In addition to purely self-built schools and PPpoE sub-dealings, more and more schools use a mixed model: the basic network is built and managed by the school itself, guaranteeing free and stable access to teaching and office; the housing area brings together operators to operate on a fee basis through PPOE sub-deals, allowing students to choose between different operators. The hybrid model takes into account the public goods of the school and the flexibility in its operation, which is the dominant trend in the current school network. In terms of future developments, with the spread of technology such as 5G, IPv6, and the Internet, the campus network NATSHEL_AUTH_BILLING also needs to support more certification methods, more sophisticated billing strategies, more open interfaces and smarter business analysis to provide stronger support for school information-building. Whatever model is chosen, a mature and stable, open interface and a tactical campus network Authentication & Billing system is the basis for successful campus network operation.
School self-building and PPPoE proxy are two typical models of operation for the campus network NATSHEL_AUTH_BILLING, each with a suitable setting. The school self-construction model is well controlled, data autonomous, suitable for schools with financial and transport capabilities; the PPOE proxy model has low financial pressure, operators bear costs, and is suitable for schools that wish to build quickly or work with operators. Whatever model is chosen, the core is a mature and stable campus network with open interfaces and flexible billing systems, NATSHEL_AUTH_BILLING, which provides security for long-term stability of the campus network.
