+\section{Interfaces}
+\label{sec:interfaces}
+The following table contains a brief description of the interfaces used inside a GSM network.
+On the upper part the interfaces for the Network Subsystem are listed and on the lower part the interfaces for the Base Station Subsystem can be found.

+Name &Between &Function\\
+\midrule
+$A$ &MSC $\leftrightarrow$ BSS &BSS management data for Mobility Management\\
+ & &and Call Control\\
+$B$ &MSC $\leftrightarrow$ VLR &MSC receives data about MSs in the current area\\
+ & & and sends data from Location Updates\\
+$C$ &MSC $\leftrightarrow$ HLR &MSC can request routing data during call setup\\
+ & &and send \eg charging information\\
+$D$ &HLR $\leftrightarrow$ VLR &Exchange of location-dependent subscriber data\\

+$E$ &MSC $\leftrightarrow$ MSC &Executing a Handover when subscriber changes\\
