What is tracking area code in LTE?
The Location Area Code/Tracking Area Code, abbreviated as LAC/TAC, is an identifier of the location area within an MNO’s network. This part of the code can be represented using hexadecimal values with a length of two octets. The served area of a cellular radio network is usually divided into location areas.
What is eNB ID in LTE?
evolved NodeB IDentifier. Used to identify an eNodeB uniquely within a Public Land Mobile Network (PLMN). The eNB-ID can have either 20 bits or 28 bits. It is also comprised within the Global eNB-ID, which uniquely identi- fies an eNodeB globally.
What is MMEI in LTE?
The MME IDs Each MME has three main identities. An MME code (MMEC) uniquely identifies the MME within all the pool areas. A group of MMEs is assigned an MME Group Identity (MMEGI) which works along with MMEC to make MME identifier (MMEI). A MMEI uniquely identifies the MME within a particular network.
What happens in mode tracking area update?
The value of timer T3412 is sent by the network to the UE in the ATTACH ACCEPT message and can be sent in the TRACKING AREA UPDATE ACCEPT message. Combined TAU – The UE operating in CS/PS mode 1 or CS/PS mode 2, in state EMM-REGISTERED, shall initiate the combined tracking area updating procedure.
What is a tracking area?
Tracking Area, abbreviated as TA, is a set of cells. A tracking area is the LTE (Long-Term Evolution) counterpart of the location area and routing area. Tracking areas can be grouped into lists of tracking areas (TA lists), which can be configured on the User Equipment (UE).
What is tracking area identifier?
The Tracking Area identity is the identity used to identify tracking areas. The Tracking Area Identity is constructed from the MCC (Mobile Country Code), MNC (Mobile Network Code) and TAC (Tracking Area Code).
What is cell ID and LAC?
LAC means Location Area Code, which is a group of cell towers. And CID stands for Cell Identification, referring to the cell number and sometimes a sector. In other words, the CID tells you where the antenna is located and which direction it faced.
What does gNodeB stand for?
Node B vs eNodeB vs gNodeB Node B, Evolved Node B (eNodeB) and Next Generation Node B (gNodeB) are radio base stations that allow mobile phones to connect to 3G, 4G and 5G mobile networks.
What is Guti and Gummei?
The GUTI (Globally Unique Temporary Identity) has two main components, the GUMMEI (Globally Unique MME Identifier) that uniquely identifies the MME that allocated the GUTI and the M-TMSI (M-Temporary Mobile Subscriber Identity) that provides for an unambiguous identity of the UE within this MME.
What is S TMSI and M-TMSI?
The S-TMSI is similar in format to the P-TMSI. It is used to protect the subscribers IMSI during NAS interaction as well as identifying the MME (Mobility Management Entity) or MME pool that is responsible for the UE. The S-TMSI is constructed from the MMEC (MME Code) and the M-TMSI.
What is tracking area in 5g?
The Registration Area in 5GS is a list of one or more Tracking Areas (TA list), • The UE performs Registration update due to mobility when moving outside its Registration Area i.e. TA list, • The UE in idle state also performs periodic Registration update when the periodic Registration update timer expires.
What is Tai in 4g?
Tracking Area Identity. The Tracking Area identity is the identity used to identify tracking areas. The Tracking Area Identity is constructed from the MCC (Mobile Country Code), MNC (Mobile Network Code) and TAC (Tracking Area Code).
What is tracking area in LTE?

What is TAC (tracking area code)?
Tracking Area Code ( TAC) is a 3GPP fixed length (of 2 octets) internationally Unique Identifier for a Tracking Area within the Public Land Mobile Network ( PLMN ). Tracking Area Code tracking area identification shall be coded using a full hexadecimal representation.
What is a tracking area (Ta)?
In LTE mobile network, every eNB consists of several cells, and every group of cells, are grouped into a Tracking Area (TA). Therefore, we can say that, the the mobile network consists of several TAs.
