How does mobile switching center work?
Mobile Switching Center It acts as a control center of a Network Switching Subsystem (NSS). The MSC connects calls between subscribers by switching the digital voice packets between network paths. It also provides information needed to support mobile service subscribers.
What are the functions of MSC Mobile Switching Center?
Mobile Services Switching Center (MSC) The MSC performs the switching of calls between the mobile and other fixed or mobile network users, as well as the management of mobile services such as registration, authentication, location updating, handovers, and call routing to a roaming subscriber.
What are the main components in a mobile switching center?
The Mobile Switching Center connects to the following elements:
- Home Location Register (HLR) for obtaining data about the SIM and mobile services ISDN number (MSISDN; i.e., the telephone number).
- Base Station Subsystem (BSS) which handles the radio communication with 2G and 2.5G mobile phones.
What is the relationship between a base station and a mobile switching center?
The MSC is structured so that base stations connect to it, while it connects to the PSTN. Because cellphones connect to these base stations, all forms of communication, whether between two cell phones or between a cell phone and a landline telephone, travel through the MSC.
