一、通信系统EIR是什么?
在移动通讯网络中,EIR多指接入终端设备识别码。详细说明如下:
1、EIR:Equipment Identity Register 设备识别寄存器
EIR在基站里面,存储着基站下所有移动设备的国际移动设备识别码(IMEI),通过核查三种表格(白名单、灰名单、黑名单)使用得网络具有防止无权用户接入、监视故障设备的运行和保障网络运行安全的功能。每个出厂具有入网许可证的手机都有一个唯一的硬件编号,类似电脑的MAC地址,全球唯一。对于手机来说,这个编号叫做国际移动设备识别码(IMEI)。
2、EIR: Excess Information Rate 超出信息速率,承诺提供给用户的最大带宽。
EIR与CIR(承诺信息速率)都是专线业务非常重要的一种业务需要,传统的基础数据专线业务如帧中继和ATM都能提供CIR/EIR。
3、简单介绍下EIR识别的流程:
Equipment Identity Register
简单介绍一下在移动通信中设备识别的程序,手机用户发起呼叫,移动交换中心(MSC)和拜访位置寄存器(VLR)向移动台(手机)请求IMEI,并把它发送给EIR,EIR将收到的IMEI与白、黑、灰三种表进行比较,把结果发送给MSC/VLR,以便MSC/VLR决定是否允许该移动台设备进入网络。因此如果该移动台使用的是偷来的手机或者有故障未经型号认证的移动设备,那么MSC/VLR将据此确定被盗移动台的位置并将其阻断,对故障移动台也能采取及时的防范措施。我们通常所说的通过网络追踪器追踪被盗手机就是通过EIR实现的。沃达丰公司等网络运营商开始使用这项业务对被盗手机进行监测。可惜的是我国基本上没有采用EIR对IMEI进行鉴别,而且如果被盗手机更换网络和修改IMEI那么EIR也将无能为力。
二、What is EIR? Understanding the EIR Acronym in Finance
When it comes to financial terms and acronyms, it's easy to feel overwhelmed. One such acronym that often pops up in discussions related to finance is EIR. What exactly does EIR stand for, and what does it mean in the context of finance? In this article, we will delve into the world of finance to demystify the EIR acronym and help you understand its significance.
What is EIR?
EIR stands for Effective Interest Rate. In finance, the EIR refers to the actual annual interest rate that takes into account the compounding of interest over time. Unlike the nominal interest rate, which is the stated interest rate without considering compounding, the EIR provides a more accurate representation of the true cost of borrowing or the return on investment.
Why is EIR important in finance?
The Effective Interest Rate is a crucial metric in finance because it allows borrowers and investors to accurately assess the cost or return on their financial transactions. By factoring in compounding, the EIR provides a more realistic picture of the interest expenses or returns over time.
Calculating EIR
Calculating the Effective Interest Rate involves taking into account the nominal interest rate, the compounding frequency, and the time period. The formula for calculating EIR varies depending on the specific financial instrument or transaction. However, in general, it involves using mathematical calculations or specialized software to determine the EIR accurately.
Applications of EIR
The EIR is widely used in various financial scenarios. For example, when applying for loans, borrowers can compare different loan offers by considering the EIR, enabling them to make informed decisions based on the true cost of borrowing. Similarly, investors can evaluate the returns on investment opportunities by examining the EIR to determine the most profitable ventures.
Limitations of EIR
While the Effective Interest Rate provides valuable insights, it's essential to note its limitations. The EIR assumes a constant interest rate throughout the entire duration of a financial transaction, which may not always reflect reality. Additionally, it may not consider other factors such as fees or charges associated with the transaction, which can impact the overall cost or return.
Conclusion
In conclusion, the EIR acronym in finance stands for Effective Interest Rate. It is a crucial metric that takes into account the compounding of interest over time and provides a more accurate representation of the true cost of borrowing or the return on investment. Understanding the EIR can help borrowers and investors make informed financial decisions. So the next time you come across the EIR acronym, you'll have a better understanding of its significance in finance.
Thank you for taking the time to read this article. We hope that it has helped you gain a better understanding of the EIR acronym in finance and its importance in assessing the true cost of borrowing or the return on investment. Stay tuned for more informative articles!
