Title:	Adding UE Capabilities to Classmark Change RR message

Background

This CR proposes to change the CLASSMARK CHANGE RR message for the handling of the UE Capabilities. These new capabilities for UMTS can be handled similar to MS Classmark 2 and 3 during the establishment of connection in GSM access mode. 
Discussion

UE Capabilities are proposed to be stored in the serving radio access network (BSS), when received in L3 RR messages in the GSM access mode similar like the radio part of GSM MS Classmark 2 and 3 are stored. 
The UE sends the UE Capabilities in the Um interface message CLASSMARK CHANGE. The sending is triggered by Classmark enquiry from the network. 
The change to A-interface message for passing UE Capabilities on to the core network is discussed in another CR. 
Reasons to change

The BSS shall need UE Capabilities in case the Relocation is possible from GSM to UMTS.
The attached CR towards GSM 04.18 describes in details the changes needed to Classmark Change RR message.

Reason for 
change:
	The proposed change will add the UE capabilities for UTRAN to the Classmark Change RR message. The change will enable to retrieve these capabilities from UMTS capable terminal using the GSM radio access with the CM enquiry from the network. The UE may also send the UE capability in RR Classmark Change when it starts to measure on UMTS.

9.1.11.1	Additional Mobile Station Classmark Information
This IE shall be included if and only if the CM3 bit in the Mobile Station Classmark IE is set to 1.
9.1.11.2	Mobile Station Classmark
This IE shall include for multiband MS the Classmark 2 corresponding to the frequency band in use.
9.1.11.3	UE Capability Information for UTRAN 
This IE shall be included if MS is capable for UTMS radio access. This IE shall include the UE capabilites for UTRAN.

10.5.2.48	UE Capability Information 
The UE Capability Information information element gives all parameters related to the UE capabilites for UTRAN.
The UE Capability Information information element is coded as shown in figure 10.5.2.48/GSM 04.18 and table 10.5.2.48/GSM 04.18.
The UE Capability Information is a type 4 information element with a minimum length of 4 octets. The maximum length depends on the parameters, which are formatted and coded according to the TS 25.331 [80]
