ECGI和CGI用于LTE和GSM网络 [英] eCGI and CGI for LTE and GSM networks

问题描述

我试图确定UE被连接到CGI（该小区全局标识符）。

I'm trying to determine the CGI (the Cell Global Identifier) the UE is connected to.

从3GPP规范，它的定义如下：

From the 3GPP specs, it's defined as follows:

• 3G：CGI = PLMN-ID + LA code + CID


• 4G：ECGI = PLMN-ID + ECI

我已经可以从系统中获取LAC（位置区code）和CID（小区ID）。我可以生成PLMN-ID由MCC（移动国家code）和MNC（移动网络code）。

I can already get the LAC (location area code) and CID (Cell ID) from the system. And I can generate the PLMN-ID from the MCC (Mobile Country Code) and MNC (Mobile Network Code).

我的问题是可以我也从系统中获得CGI？

My question is can I also get the CGI from the system?

推荐答案

的CGI（2G和3G）和ECGI（OFR 4G）始终是一个15十进制数字code

The CGI (2G and 3G) and eCGI (ofr 4G) is always a 15 decimal digit code

有关2G 3G和4G网络的五个第一个数字是MCC（移动国家code）和MNC（移动网络code）

For 2G 3G and 4g networks the five first digits are the MCC (Mobile Country Code) and the MNC (Mobile Network Code)

有关2G和3G networs未来5位是LAC（位置区域code）和LAC在过去五年的小区ID

For 2G and 3G networs the next 5 digits are the LAC (Location Area Code) and the last five the Cell ID within the LAC

有关4G networs的10个数字然后eNB与分裂的7位code加上3位code的小区ID。

For 4G networs the 10 digits are then eNB and split in a 7 digits code plus a 3 digits code for the Cell ID.

问题的关键是，有些系统或应用程序可与德全CGI或ECGI等系统与spparate块的工作原理：（MCC-MNC-LAC-CID或MCC-MCC-的eNB）

The point is that some systems or applications works with de whole CGI or eCGI and other systems works with the spparate blocks: (MCC-MNC-LAC-CID or MCC-MCC-eNB)

从15位code到块翻译requiere知道电池技术，以知道，如果你有两个5位数块或在7和3位块拉斯10位分割。

Translating from a 15 digit code to the blocks requiere knowing the cell technology in order to know if you have to split the las 10 digits in two 5 digits blocks or in a 7 and 3 digits blocks.

在另一方面，如果你想翻译块到15位code，你必须垫然后块，达到15位长，所以如果你有213-01-123-5它可以是213010012300005（2G或3G）或21301000012305

In the other hand, if you want to "translate" the blocks into a 15 digits code, you have to pad then blocks to reach the 15 digits length, so if you have 213-01-123-5 it can be 213010012300005 (2G or 3G) or 21301000012305

谷歌API OFR地理位置有技术的非必填字段，但我认为它应该是强制性的。

Google API ofr geolocation has a non-mandatory field for technology, but I think that it should be mandatory.

我恐怕这是真的要成为一个问题。

I'm afraid that it is really going to be a problem.
