+ * coded according to Location Area Identification in 3GPP TS 24.008. The CN-Id is an integer defined by O&M. The
+ * least significant bit of the CN-Id field is bit 1 of octet 7 and the most significant bit is bit 8 of octet 6. If the CN-Id does
+ * not fill the field reserved for it, the rest of the bits are set to '0'.
