General
If set on the mobile phone, enter the Personal Identification Number (PIN). In response to this, the mobile phone system contacts the most favorably positioned Base Transceiver Station (BTS) and then routes the data over the Base Station Controller (BSC) to the Mobile Service Switching Center (MSC). Access authorization for the mobile telephone network is issued following inquiry of the required data in the Mobile Service Switching Center (MSC) from the Authentication Center (AC).
After registering in the mobile telephone network, in vehicles with code (386) Mobile phone, the name of the mobile telephone network is displayed on the mobile phone screen. If the next nearest Mobile Service Switching Center (MSC) is not the one entered by the user when logging-in his/her mobile phone as a mobile phone subscriber in the Home Location Register (HLR), then he/she is registered in the Visitor Location Register (VLR). The Mobile Service Switching Center (MSC) then establishes contact with the user's Mobile Service Switching Center (MSC), in which the user is entered in the Home Location Register (HLR) as a mobile phone subscriber, requests the necessary data and issues access authorization to the mobile telephone network.
The Mobile Service Switching Center (MSC) thus automatically knows where the subscriber is located and it can then route the incoming phone calls to him/her as long as he/she remains logged into the mobile telephone network. Any change of location is updated in the Mobile Service Switching Center (MSC).
