The first three months of WiFi’s network billing system are a problem-focused outbreak. No matter how many tests the selection phase has tested, the deployment phase has been adjusted to reveal unexpected problems when it is actually running throughout the school. These issues are mostly not the bug of the system itself, but rather the mismatch between configuration parameters and real use. The wivi team will need to do more than just repair over the three months, so that the problem can be sorted, root causes found and treatment preset.
Failed to load authentication page is type I HF problem
The most common user complaints were made during the initial online WiFi network billing system"Can't open WiFi authentication page after the connection"The problem looks simple, but there are several root causes. The most common is the DNS problem.——Users get IP after WiFi is connected, but DNS is not configured and the domain name of the authentication page cannot be solved. Next is the HTTPS certificate problem——Some phones are not friendly to self-signed certificates and directly intercept the loading of authentication pages.——AC re-direction rules point to the wrong authentication server address. Such questions are sorted first to confirm whether users have access to IPs, DNSs are normal and re-directed URLs correct, and are excluded in this order.
The abnormal billing data is the second type of patient question.
User feedback"I'm not using that much traffic."or"I'm full, but the balance hasn't changed.", such problems are common in the early stages of WiFi's online billing system. The root causes may be several: delay in data collection for billing engines (the real-time charge system has been delayed by a few minutes is normal), traffic statistics include delays in returning differences between retransmission traffic, button and button when switching to a set of meals."User-based diagnostics"tool, you can pull the data by entering a user account, otherwise each manual query is too slow. The first month on line recommends an active sample of user-based data audit, which would be better to identify problems in advance than waiting for users to complain.
The issue of equipment compatibility is the most widespread in category III
WiFi network billing systems are online, with a wide variety of mobile phones, computers and flats. Some phone calls automatically eject the authentication page after WiFi, some without them; others have stable connections after certification, some disconnected within minutes. These problems will not be fully exposed during the testing phase because there is only limited equipment to test."Device Compatibility Library", document each problematic model of equipment, problem performance, and temporary solutions. After a period of accumulation, certain brands are identified as having common problems, which can be tailored for configuration or user guidance issued.
The peak performance bottleneck is the fourth category of advanced planning
WiFi’s network billing system may not have real peak pressure in the early part of the online cycle, but this does not mean that it has no performance bottlenecks. The peak period usually occurs in dormitory areas between 8 p.m. and 11 p.m. or when the large post-test building is connected to the Internet.——Simulates the amount of authentication and distribution during peak periods, observing system response time and resource occupancy. If there is a slower response in simulation tests, an increased failure rate for certification indicates that systems need to be expanded or subdued and not processed until they are really high.
User error is the most expensive type 5 communication problem.
WiFi online, a significant number of users complain that the system is not a problem but that the user does not work properly. Users forget passwords, enter incorrect accounts, turn off pages without completing authentication, and think WiFi can be connected to the Internet without being certified. These questions are not difficult at the technical level, but they are costly to communicate with.——The user doesn't understand why authentication is necessary, and feels"You didn't have to be so much trouble.". The guide team prepares user guidance materials, including graphics lessons, video lessons, and FAQ, covering common operating scenes. It is recommended that the guide be posted on the hall of the dormitory at an early stage online, that help links be placed on certified pages so that users can solve problems themselves and reduce client service stress.
The problem remixing mechanism was the most important working habit of the first three months.
The problem of the first three months, if not repeated, will always arise.——The re-dossing is a practice that has been developed in the first three months, and when the system enters stabilization period, it will improve its efficiency.
