Liaison Statement on SoLSA exclusive access

SMG2 WPA thanks SMG3 WPA/ TSG CN1 for their comments to the LS on SoLSA exclusive access Tdoc 736/99. According the information received from SoLSA discussions in SMG3 WPA/TSG CN1 the CR 04.08-528r1 has not been accepted. In addition it has been stated in the SMG3 WP/TSG CN1 meeting, that a Classmark 3 based solution should be considered in SMG2 WPA. 
The CR 04.08-A546 r1 has been discussed in SMG2 WPA and accepted to be proposed for SMG3 WPA/TSG CN1 for acceptance. 
Due to the time schedule for SoLSA, SMG2 WPA hopes that the CR can be approved by SMG3 WPA/ TSG CN1 in time for the SMG #29.
Enclosed is CR 04.08-A546 r1.

Other 
comments:	The page numbering in 04.08 version 7.0.1 seems to be in error. Page 551 (10.5.5.12a) refers to the second occurrence of that page number.	

The mobile station in packet idle mode (only applicable to mobile station supporting GPRS) may initiate packet access in the same cell before T3122 has expired, see GSM 04.60 and section 3.5.2.1.3.4.
After T3122 expiry, no CHANNEL REQUEST message shall be sent as a response to a page until a PAGING REQUEST message for the mobile station is received.
3.3.1.1.4	Assignment completion
The immediate assignment procedure is terminated on the network side when the main signalling link is established. Timer T3101 is stopped and the MM sublayer on the network side is informed that the RR entity has entered the dedicated mode.
On the mobile station side, the procedure is terminated when the establishment of the main signalling link is confirmed. The MM sublayer is informed that the RR entity has entered the dedicated mode.
3.3.1.1.4.1	Early classmark sending
Early classmark sending consists in the mobile station sending as early as possible after access a CLASSMARK CHANGE message to provide the network with additional classmark information.
A mobile station which implements the  Controlled Early Classmark Sending  option shall perform the early classmark sending if and only if explicitly accepted by the network, as indicated in the last reception in the accessed cell of the SYSTEM INFORMATION TYPE 3 message.
A mobile station which implements one or more of the  multiple band support  options shall also implement the  Controlled Early Classmark Sending  option.
A mobile station which implements the  multislot capability  option shall also implement the  Controlled Early Classmark Sending  option.
A mobile station that implements some form of treatment of UCS2 alphabet (see TS GSM 03.38) encoded character string (e.g., in short message, or in USSD string) may indicate so in the classmark. (An example is a Mobile Equipment able to display UCS2 encoded character string.) In such a case, it should also implement the « Controlled Early Classmark Sending » option. It is the mobile station responsibility to provide the UCS2 support information in due time. If the network needs this information and the mobile station did not provide it, the network may assume that the Mobile Equipment does not support UCS2.
A mobile station which implements the R-GSM band (see GSM 05.05) shall also implement the  Controlled Early Classmark Sending  option.
A mobile station which implements the extended measurement function shall also implement the  Controlled Early Classmark Sending  option.
A mobile station which implements the GPRS option shall also implement the  Controlled Early Classmark Sending  option.
A mobile station which implements the SoLSA option shall also implement the  Controlled Early Classmark Sending  option.
A mobile station which implements the  Controlled Early Classmark Sending  option shall indicate it in the classmark (ES IND bit). 
10.5.1.7	Mobile Station Classmark 3
The purpose of the Mobile Station Classmark 3 information element is to provide the network with information concerning aspects of the mobile station. The contents might affect the manner in which the network handles the operation of the mobile station. The Mobile Station Classmark information indicates general mobile station characteristics and it shall therefore, except for fields explicitly indicated, be independent of the frequency band of the channel it is sent on.
The MS Classmark 3 is a type 4 information element with a maximum of 14 octets length.
The value part of a MS Classmark 3 information element is coded as shown in figure 10.5.7/GSM 04.08 and table 10.5.7/GSM 04.08.
NOTE:	The 14 octet limit is so that the CLASSMARK CHANGE message will fit in one layer 2 frame.
SEMANTIC RULE : a multiband mobile station shall provide information about all frequency bands it can support. A single band mobile station shall not indicate the band it supports in the Multiband Supported field in the MS Classmark 3.
SEMANTIC RULE : a mobile station shall include the MS Measurement Capability field if the Multi Slot Class field contains a value of 19 or greater (see GSM 05.02).
Typically, the number of spare bits at the end is the minimum to reach an octet boundary. The receiver may add any number of bits set to "0" at the end of the received string if needed for correct decoding.

Multiband Supported (3 bit field)

Band 1 supported (third bit of the field)
  0		P-GSM not supported
  1		P-GSM supported

Band 2 supported (second bit of the field)
  0		E-GSM or R-GSM not supported
  1		E-GSM or R-GSM supported

Band 3 supported (first bit of the field)
  0		DCS 1800 not supported
  1		DCS 1800 supported

The indication of support of P-GSM band or E-GSM or R-GSM band is mutually exclusive.

When the 'Band 2 supported' bit indicates support of E-GSM or R-GSM, the presence of the  <R Support> field, see below, indicates if the E-GSM or R-GSM band is supported.

In this version of the protocol, the sender indicates in this field either none or two of these 3 bands supported. However, if only one band is indicated, the receiver shall ignore the Associated Radio Capability 2.

For single band mobile station all bits are set to 0.

Associated Radio capability 1 and 2

If either of P-GSM or E-GSM or R-GSM is supported, the radio capability 1 field indicates the radio capability for P-GSM, E-GSM or R-GSM, and the radio capability 2 field indicates the radio capability for DCS1800 if supported, and is spare otherwise.

If none of P-GSM or E-GSM or R-GSM are supported, the radio capability 1 field indicates the radio capability for DCS1800, and the radio capability 2 field is spare.

The radio capability contains the binary coding of the power class associated with the band indicated in multiband support bits (see GSMß05.05).

R Support 

In case where the R-GSM band is supported the R-GSM band assciated radio capability field contains the binary coding of the power class associated(see GSMß05.05). A mobile station supporting the R-GSM band shall also when appropriate, see 10.5.1.6, indicate its support in the 'FC' bit in the Mobile Station Classmark 2 information element.

Note:	the coding of the power class for P-GSM, E-GSM, R-GSM and DCS 1800 in radio capability 1 and/or 2 is different to that used in the Mobile Station Classmark 1 and Mobile Station Classmark 2 information elements.

Multi Slot Class (5 bit field)

In case the MS supports the use of multiple timeslots then the Multi Slot Class field is coded as the binary representation of the multislot class defined in TS GSM 05.02.

UCS2 treatment

This information field indicates the likely treatment by the mobile station of UCS2 encoded character strings. If not included, the value 0 shall be assumed by the receiver.

0	the ME has a preference for the default alphabet (defined in GSM 03.38)
	over UCS2.

1	the ME has no preference between the use of the default alphabet and the
	use of UCS2.

Extended Measurement Capability

This bit indicates whether the mobile station supports 'Extended Measurements' or not

0	the MS does not support Extended Measurements

1	the MS supports Extended Measurements

0	the ME does not support SoLSA

1	the ME supports SoLSA

10.5.5.12a	MS Radio Access capability
The purpose of the MS RA capability information element is to provide the radio part of the network with information concerning radio aspects of the mobile station. The contents might affect the manner in which the network handles the operation of the mobile station.  
The MS RA capability is a type 4 information element. 
The value part of a MS RA capability information element is coded a shown table 10.5.146/GSM 04.08. 
-	SEMANTIC RULE : Among the three Access Type Technologies GSM 900-P, GSM 900-E and GSM 900-R only one shall be  present. 
-	Error handling : If a received Access Technology Type is unknown to the receiver, it shall ignore all the corresponding fields;
-	If within a known Access Technology Type a receiver recognizes an unknown field it shall ignore it.
-	See more details about error handling of MS radio access capability in TS GSM 08.18.
