Reason for 
change:
	A new System Information message type 5gamma is introduced in order to provide dual mode (UMTS/GSM) mobiles with information about UMTS neighbouring cells. The new coding for this new message is added in Information Elements SACCH Information and System Info Type.

The Length field (octet 2) indicates in binary the total remaining length of the element (octets 3 - N).
The Number of SI messages field (octet 3) indicates in binary the number of messages contained in the element.
The coding of each of these messages consists of a type field (Type of n’th msg), a length field (Length of n’th message) and a message field (n’th message).
The "Type of n’th msg" field indicates the type of SYSTEM INFORMATION, or an EXTENDED MEASUREMENT ORDER message that follows in the "n’th message" field. It is coded as follows:
Value			 Message
0 0 0 0  0 1 0 1		SYSTEM INFORMATION 5
0 0 0 0  0 1 1 0		SYSTEM INFORMATION 6
0 0 0 0  1 1 0 0		SYSTEM INFORMATION 5gamma
0 0 0 0  1 1 0 1		SYSTEM INFORMATION 5bis
0 0 0 0  1 1 1 0		SYSTEM INFORMATION 5ter
0 1 0 0  0 1 1 1		EXTENDED MEASUREMENT ORDER
All other values are reserved.
The "Length of n’th SI message" field indicates in binary the length of the "n’th message" field that follows.
The "n’th message" field contains a complete SACCH message as defended in GSM 04.08.
9.3.30	System Info Type
This element is used to indicate the type of SYSTEM INFORMATION message or an EXTENDED MEASUREMENT ORDER message as defined in GSM 04.08 .
