What is MNC and MCC for GSM
MCC MNC – Telecom
What is mcc and mnc :- Both are very first question in your mind when you start learning on telecom its basic behind numbering system in telecom lets understand each one in details.
MNC full form in telecom : Mobile Network Code.
MCC full form in telecom : Mobile Country Code.
What is the meaning of MCC? :
Mobile Country Code（MCC meaning) – MCC consists of 3 decimal numbers. It indicates the home country of the mobile subscriber. MCC is composed of 3 decimal numbers. The coding range is decimal 000-999.
MCC is used in international mobile subscriber identity (IMSI) and location area identity (LAI).
1. LAI. It is periodically transmitted in system information of each cell. MCC indicates the home country of GSM PLMN. MS uses the received information as the important basis for network selection.
2. IMSI of MS. MS’s IMSI also contains MCC. It shows the resident country of the mobile subscriber. When MS logs on the network or applies for a certain service, it must report its IMSI to the network (When TMSI is unavailable.). The network uses the MCC in IMSI to judge whether this subscriber is an international roaming subscriber.
As the unique country identity standard, MCCs are allocated and managed by the International Telecommunication Union (ITU). ITU Recommendation E.212 (blue book) stipulated the MCC number for every country. Due to the special meaning of MCC, modification of it is prohibited once it has been set in the network.
What is the meaning of MNC? :
Mobile Network Code（MNC meaning) : MNC is used to uniquely identify a specific GSM PLMN network in a certain country (decided by MCC).MNC is composed of two decimal numbers. The coding range is decimal 00-99.
MNC is used in international mobile subscriber identity (IMSI) and location area identity (LAI).
LAI. It is periodically transmitted in system information of each cell. Here, MNC indicates the network number of GSM PLMN. MS uses the received information as an important basis for network selection.
IMSI also contains MNC. It shows the home GSM PLMN network of the subscriber. When MS logs on the network or applies for a certain service, it must report IMSI to the network (When TMSI is unavailable.). The network judges whether this subscriber is a roaming subscriber according to the MNC in IMSI, and uses it as one of the important parameters for addressing to subscriber HLR.
If a country has more than one GSM PLMN, different networks must have different MNC. MNC is allocated by relevant telecommunication management department of the country.
One operator can have one or more MNC (which regards to the scale provided by the service, usually one operator has one MNC.). Different operators can share the same MNC. Due to the special meaning of MNC, modification is prohibited once it has been set in the network.
What is MCC and MNC in APN?
MCC (Mobile Country Code) is a three-digit code that uniquely identifies a country in the international mobile network.
MNC (Mobile Network Code) is a two or three-digit code that identifies a specific mobile network within a country.
In the context of APN (Access Point Name), MCC and MNC are used to specify the mobile network the device should connect to when accessing mobile data services. They help in routing data traffic to the correct network in a given country.
What is MCC 313 MNC 100?
MCC 313 and MNC 100 together represent a specific combination used in mobile networks. However, without additional information, it’s not possible to identify the exact country or mobile network associated with this MCC-MNC pair. These codes are part of the larger system used in telecommunications to uniquely identify countries and mobile networks.
What is the MCC MNC prefix?
The MCC (Mobile Country Code) and MNC (Mobile Network Code) together form a prefix that uniquely identifies a mobile network worldwide. The MCC is a three-digit code representing the country, while the MNC is a two or three-digit code identifying the specific mobile network within that country. When combined, they create a prefix that helps route and manage mobile network traffic globally.
What is MNC and MCC for GSM?
In GSM (Global System for Mobile Communications), MNC (Mobile Network Code) and MCC (Mobile Country Code) are identifiers used to uniquely identify mobile networks across different countries.
MCC (Mobile Country Code)
The MCC is a 3-digit code used to identify the country of a mobile network. It is assigned by the International Telecommunication Union (ITU). Each country has a unique MCC that distinguishes it from others. For example, the MCC for the United States is 310, while for the United Kingdom, it is 234.
MNC (Mobile Network Code)
The MNC is a 2 or 3-digit code that identifies a specific mobile network within a country. It is used together with the MCC to uniquely identify a mobile operator. For example, in the United States, Verizon has the MNC of 012, while T-Mobile has the MNC of 260.
Usage
- MCC: Identifies the country where the mobile network operates.
- MNC: Identifies the specific mobile network operator within that country.
When combined, the MCC and MNC form the IMSI (International Mobile Subscriber Identity), which is used to authenticate a user on the network.
In GSM, MNC (Mobile Network Code) and MCC (Mobile Country Code) are used together to uniquely identify a mobile network operator within a specific country. They form part of larger identifiers like IMSI (International Mobile Subscriber Identity) and CGI (Cell Global Identity).
MCC – Mobile Country Code
- Identifies the country.
- Always consists of 3 digits.
- Example:
- 262 = Germany
- 310 = USA
- 404 = India
MNC – Mobile Network Code
- Identifies the mobile network operator within the country.
- Can be 2 or 3 digits.
- Example (for MCC 262, Germany):
- 01 = Telekom Deutschland
- 02 = Vodafone Germany
- 07 = O₂ Germany
Together, MCC + MNC uniquely identifies a GSM network operator globally and is used in various signaling processes like roaming, authentication, and location updates.
