What is PLMN network ID?
A PLMN is identified by a globally unique PLMN code, which consists of a MCC (Mobile Country Code) and MNC (Mobile Network Code). Hence, it is a five- to six-digit number identifying a country, and a mobile network operator in that country, usually represented in the form 001-01 or 001–001.
What is UE identity in LTE?
Identifiers for User Equipment (UE IDs) LTE networks are all IP networks. Because of such nature, UEs in an LTE network share radio and network resources. EPS entities of the LTE network allocate a UE ID to each UE to identify it.
What is the role of PLMN?
The PLMN is the term used to describe all mobile wireless networks that use earth-based stations rather than satellites. PLMN is the mobile equivalent of the PSTN. Such a system can stand alone, but often it is interconnected with a fixed system such as the public switched telephone network (PSTN).
How is PLMN ID calculated?
If storage for fewer than the maximum possible number n is required, the excess bytes shall be set to ‘FF’. For instance, using 246 for the MCC and 81 for the MNC and if this is the first and only PLMN, the contents reads as follows: Bytes 1-3: ’42’ ‘F6′ ’18’ Bytes 4-6: ‘FF’ ‘FF’ ‘FF’ etc. TS GSM 04.08 [14].
How is PLMN generated?
A PLMN is identified by the combination of Mobile Country Code (MCC), and Mobile Network Code (MNC) that the UE should treat as equivalent for the purposes of PLMN selection, cell selection/reselection and handover. The UE adds the PLMN of the current network to the received E-PLMN list before storing it.
How many types of PLMN are there in SIM card?
There are two modes for PLMN selection, Automatic and Manual explained below.
What is DRB and SRB in LTE?
In LTE there are two main types of bearers, namely the SRB (Signalling Radio Bearer) and the DRB (Data Radio Bearer). The DRB is used to carry the data associated with an EPS bearer. If you enjoy using our glossary, here are some other useful resources you might like…
What is MCC and MNC in LTE?
MCC and MNC are the acronyms of “Mobile Country Code” and “Mobile Network Code”. These codes are used to identify the country and network codes on mobile telecommunications for GSM, LTE, CDMA, or UMTS communications.
What is the PLMN identity list?
The Equivalent PLMN (E-PLMN) list allows a network to provide the UE with a list of PLMN identities. A PLMN is identified by the combination of Mobile Country Code (MCC), and Mobile Network Code (MNC) that the UE should treat as equivalent for the purposes of PLMN selection, cell selection/reselection and handover.
What is TAC in LTE network?
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.
How many SRB is LTE?
As mentioned in the LTE SRB table, there are three types of SRB in the LTE technology. SRB0 used to transfer RRC messages which use CCCH channel. SRB1 used to transfer RRC messages which use DCCH channel. SRB2 used to transfer RRC messages which use DCCH channel and encapsulates a NAS message.
What is EPS bearer in LTE?
On the other hand, an EPS bearer is a pipe through which IP packets are delivered over the LTE network, i.e., between a UE and a P-GW (UE – eNB – S- GW – P-GW). A UE can have multiple EPS bearers concurrently. So, different EPS bearers are identified by their EPS bearer ID, which is allocated by an MME.
How many digits is IMSI?
14-15 digits
An IMSI forms part of a device’s SIM profile and comprises 14-15 digits. The first 2-3 digits are the mobile country code (MCC) and the following 2-3 digits are the mobile network code (MNC). After this, there’s a unique combination of 9 or 10 digits to identify the SIM card user, and which is unique to the subscriber.
What is Msisdn used for?
On a cellular network, MSISDN (Mobile Station Integrated Services Digital Network) is the phone number which identifies a device during calls or data sessions. It performs a crucial function in ensuring secure connectivity between the different components within an IoT network.
How is PLMN selected?
PLMN Selection ( Automatic Mode or Manual Mode)
UE first selects the last RPLMN or a PLMN in the EPLMN list and attempts to register on the selected PLMN. If the registration on that PLMN is successful, the selected PLMN is displayed on the UE, and the UE can now obtain services from the operator.
How many eNodeB are in a TAC?
Tracking Area Codes (TACs) or TAs: it is group of eNodeBs in one small area with maximum number of 100 eNodeBs.
What is DRB and SRB?
What is RRC in LTE?
The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 for UMTS, in TS 36.331 for LTE and in TS 38.331 for 5G New Radio.
What is ECM in LTE?
ECM stands for EPS Connection Management and EMM stands for EPS Mobility Management in LTE technology. • These are parts of NAS (Non Access Stratum). • NAS is basically used to transport non radio signalling messages between UE and MME in LTE.
Is IMEI and IMSI the same?
The IMSI (International Mobile Subscriber Identity) is a code used by the phone company to identify the SIM on the mobile network. The IMEI (International Mobile Station Equipment Identity) is an international “Serial number” for your phone (device itself) to properly identify it on the carriers network.
How IMSI is coded?
IMSI (International Mobile Subscriber Identifier) is a number of 14-15 digits which identifies a mobile subscriber by their SIM card. It is made up of several parts, including a country code, a network code, and an individual string of digits identifying each particular card within the mobile network.
What is MSISDN in LTE?
MSISDN (Mobile Station International Subscriber Directory Number) An MSISDN is a number that uniquely identifies a subscription in a GSM or a UMTS mobile network. An MSISDN is the phone number associated with a single SIM card and is the number to which you call or send an SMS message.
What is cell selection in LTE?
Then the question is which specific single cell the UE have to register. For this UE goes through a specific decision making process to pick up a specific base station (cell) to register, this specific decision making process is called ‘Cell Selection’.
What is LAC and TAC in LTE?
What is eNodeB ID in LTE?
Enodeb-id. 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 identifies an eNodeB globally.
