In LTE network, different IDs are used to identify each entity depending on their relationship with other IDs just like different names and titles are used to refer to a person - a name (e.g. James), or a title at work (e.g. Manager James, James from Netmanias, James from Google, etc.) or at home (e.g. son, dad, uncle, etc.) - in human network. Understanding these IDs as well as the EPS entities defined in  is essential to understand LTE technologies.
We have previously discussed the LTE network architecture, our first topic in LTE area. Now we will cover LTE identification, our second topic in the area, in a series of three companion documents. This document is the first of the series and will focus on user equipment (UE) IDs. The second and third documents will specifically cover network equipment (NE) IDs and EPS sessions/bearers, respectively.
This document is organized as follows.
In Chapter 2, LTE identification is classified into different groups.
In Chapter 3 and Chapter 4, UE IDs and ME IDs are described respectively based on the classification.
In Chapter 5, the overall features of the UE and ME IDs are briefly summarized.
Hi Netmanias Team,
Please have a look for a corection on the summary part at the top of this document.
"ME IDs such as IMSI and IMSISV are explained"
I think it should be : IMEI and IMEISV.
Thank you for noticing the typo.
We have fixed some typos regarding to IMEI (IMSI -> IMEI) and posted the updated file.
Thanks again for your kind comment.
The presentation of the information related to LTE is excellent. Please accept my kudos.
Would like to point out a small error:
refer Fig 5. explaining dynamic IP address allocation. the message arrow between MME and P-GW indicates there is an interface between the two nodes. In fact, there is no such interface. The message Create Bearer request is sent by MME to S-GW which relays to P-GW.
Dear netmanias team,
Thanks for your illustrative article.
Just a comment on fig. 9. Isn't it better to have UCCI(or SIM card) in the figure instead of USIM? Because ME and USIM are not from the same category. ME is a device and USIM is an application. But UCCI can be cansidered to be a device as ME since it is an integrated circuit securely incorporating IMSI and runs USIM.
