There are risks in transferring networks, and you need to be cautious when handling them. Everything can't be perfect. It is very convenient to carry the number to the network, but there are also many things that bother you. Therefore, you need to measure the pros and cons of it before you handle it. Recently, the "Information and Communication Industry Development Plan (2016-2020)" issued by the Ministry of Industry and Information Technology mentioned that it is necessary to promote the implementation of mobile phone number portability services nationwide. And this means that in 2020, nationwide mobile phone card users will likely usher in the long-awaited port number transfer. It is understood that in October 2006, the port number transfer policy was introduced. On November 22, 2010, the Ministry of Industry and Information Technology officially adopted Tianjin and Hainan as the first pilot cities to carry the number to the network. On September 20, 2014, the second batch of portable number transfer network pilots landed in Jiangxi, Hubei, and Yunnan. In August this year, the Ministry of Industry and Information Technology clearly stated in a “13th Five-Year Plan†document that it is necessary to implement the port number transfer service nationwide in 2020. Although China has begun to implement the port number transfer policy a few years ago, due to the complicated process procedures and technical problems of third-party platforms, the port number transfer network has not been widely promoted, and the results have been minimal. According to the Ministry of Industry and Information Technology, as of the end of June 2016, more than 450,000 users in the five provinces (cities) conducting the pilot number transfer network used the number portability service. Among them, China Telecom brought in 168,000 and carried out 66,000; China Mobile brought in 162,000 and carried out 250,000; China Unicom brought in 147,000 and carried out 161,000. The number of users transferred to the China Telecom network is the highest, while China Mobile has the highest user churn rate. Compared with the progress of porting numbers in other countries, China is still in its infancy. According to statistics from previous operators, global mobile users have grown to 4.7 billion in 2016. According to media statistics, more than 70 countries around the world have implemented port number transfer, which is equivalent to the implementation of the port number transfer in the area where 4 billion users are involved. After nearly seven years of development, only five provinces (cities) in the country have been transferred to the pilot port number, and have not been fully liberalized. The report of the Institute of Telecommunications Research of the Ministry of Industry and Information Technology pointed out that it is difficult for users to transfer their numbers to the network. The reason is that operators avoid artificial user churn and set various thresholds through technical means to prevent users from carrying out. At the moment, the mobile phone number has already occupied an important position like the ID number of people. The number used for many years has a certain feeling, expanding a lot of contacts, socializing, and binding with a lot of information, such as bank cards, Alipay, WeChat, important registration files, etc., and changing cards requires too much effort to unbind and re-bind. In addition, for many of the current package tariffs and network services, the user's needs are not met. Therefore, the user's voice for the port number is getting higher. However, some people have different opinions on the advantages and disadvantages of the port number transfer service. In the industry's senior analyst Occam razor, the port number transfer is not feasible. First of all, jurisprudentially, the mobile phone number is a subject matter of your contract with the operator. It only exists because of the contract itself. Secondly, as the operator and the management department of the management operator, three major operations must be considered. The problem of resource allocation between quotients does not allow serious misappropriation of resource allocation; in addition, there are some cases in which foreign countries have transferred to the Internet, but only a few operators have a means of promotion, and port number transfer is not necessary for operators. Obligation provided. After changing the network, it will also involve the change of customer service and data sharing. When encountering security problems, it may also result in a situation of “cutting and resolvingâ€. In addition, when changing the network, problems related to inter-operator network settlement and system upgrade will also bring many problems. For operators whose strength needs to be improved, they are at a disadvantage in the competition. If they carry the port number transfer, they will face a large number of users losing in a short period of time, and the revenue will inevitably drop sharply. At present, in addition to Tianjin, Hainan, Jiangxi, Hubei, and Yunnan, the participation in the pilot number transfer network is still far from the national promotion. Despite the current problems of technology and resource allocation balance in the number portability network, the communication market may be turbulent at first, but full free market competition can finally find balance and solutions. In my opinion, the port number transfer is the trend of the times. Operators are not as worried about the loss of users. It is better to upgrade their services, more affordable package combinations, and better networks. Piezoelectric Buzzer For Driver Circuit Built-in
The piezoelectric buzzers (for Driver Circuit Built-in) offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a piezo Buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous for any battery operated device. Since piezo buzzers don`t have a magnet in their construction, it eliminates EMI/EMC issues.
