Initial Conditions
System Simulator:
- 1 GAN cell, default parameters
Mobile Station:
- MS in GA-CSR-DEDICATED state in service of GAN cell and a voice call is ongoing.
Foreseen Final State of the MS
MS in GA-CSR- IDLE state in service of GAN cell.
Test Procedure
A voice call is ongoing. The SS configures a traffic channel by transmitting corrupted GA-CSR ACTIVATE CHANNEL to the MS. In the corrupted GA-CSR ACTIVATE CHANNEL message “Sample Size” octet 3 is set to “1” (1ms), which is a undefined value.
MS fails to establish the traffic channel and transmits a GA-CSR ACTIVATE CHANNEL FAILURE and acts as if the GA-CSR ACTIVATE CHANNEL was not received.

82.6.1.1.1 Conformance requirement
|
On receipt of the GA-CSR CLASSMARK ENQUIRY message or in case of "early classmark sending" procedure based on the system information indication received in GA-RC REGISTER ACCEPT message, the mobile station sends a GA-CSR CLASSMARK CHANGE message to the GANC.
The MS shall include the IE "Mobile Classmark 2" in the GA-CSR CLASSMARK CHANGE. It may also contain a IE "Mobile Classmark 3" depending on the MS capabilities.
In addition a MS supporting UTRAN sends a GA-CSR UTRAN CLASSMARK CHANGE message.
The Classmark Enquiry Mask information element in the GA-CSR CLASSMARK ENQUIRY message indicates the type of request. If the Classmark Enquiry Mask information element is not included in the GA-CSR CLASSMARK ENQUIRY message, this indicates a request for GA-CSR CLASSMARK CHANGE message.

3GPP TS 44.318 subclause 7.8.1:
The purpose of this procedure is to transfer, upon request from the MS (and under the control of the GAN), a connection between MS and GAN to another radio access technology (e.g. GERAN).
The procedure is applicable in GA-CSR-DEDICATED state.
The procedure may be initiated by the MS based on:
- local measurements of GAN coverage signal quality;
- reception of a GA-CSR UPLINK QUALITY INDICATION message indicating poor uplink quality in the UL Quality Indication IE; If the UL Quality Indication IE indicates "Network problem" a handover out to GERAN or UTRAN should be attempted. In case the UL Quality Indication information element shows "Radio problem" or "Undetermined problem" a search for a new access point should be done before the handover out is initiated;
- reception of RTCP packets indicating poor uplink quality;
- excessive loss or delay in the received RTP packets.
When the MS decides to trigger the handover from GAN, it shall:
- send a GA-CSR HANDOVER INFORMATION message to the network including a list of candidate/ target cell identifiers ranked in order of preference which is the most recent list available from the other radio access technology (e.g. GSM RR) and including the received signal strength for each identified GERAN or UTRAN cell. The MS may include GERAN cells, UTRAN cells or both.
3GPP TS 44.318 subclause 7.8.3:
The MS shall:
- suspend all NAS layer signalling transmissions;
- start the connection establishment to the target radio access technology (e.g. GERAN) by using the contents of the Handover From GAN Command IE. This message carries information about the candidate/ target cell identifier and radio parameters relevant for the target radio access technology;
A MS that is simultaneously operating in GPRS and CS modes over GAN shall follow the procedure as outlined in 3GPP TS 43.055 when it switches to target cell.
NOTE: The requirements concerning the establishment of the radio connection towards the target radio access technology (e.g. GERAN) and the signalling procedure are outside of the scope of this specification.
3GPP TS 44.318 subclause 7.8.4:
Upon successfully completing the handover, the GANC should:
- release all radio resources associated with the GAN connection.
Upon successfully completing the handover, the MS shall:
- switch to target radio access technology (e.g. GERAN) mode i.e. detach the GA-RR entity from the RR-SAP;
- enter GA- RC -REGISTERED state.
NOTE: The release of the GAN radio resources is initiated from the target RAT. The MS may deregister from the GANC (as defined in sub-clause 6.4) after successfully completing the handover. If the MS chooses to deregister from the GANC, it may do so either immediately after successfully completing the handover or after sending the GA-CSR RELEASE COMPLETE message to the GANC in response to the GA-CSR RELEASE message from the GANC.

3GPP TS 44.318 subclause 7.8.1:
The purpose of this procedure is to transfer, upon request from the MS (and under the control of the GAN), a connection between MS and GAN to another radio access technology (e.g. GERAN).
The procedure is applicable in GA-CSR-DEDICATED state.
The procedure may be initiated by the MS based on:
- local measurements of GAN coverage signal quality;
- reception of a GA-CSR UPLINK QUALITY INDICATION message indicating poor uplink quality in the UL Quality Indication IE; If the UL Quality Indication IE indicates "Network problem" a handover out to GERAN or UTRAN should be attempted. In case the UL Quality Indication information element shows "Radio problem" or "Undetermined problem" a search for a new access point should be done before the handover out is initiated;
- reception of RTCP packets indicating poor uplink quality;
- excessive loss or delay in the received RTP packets.
When the MS decides to trigger the handover from GAN, it shall:
- send a GA-CSR HANDOVER INFORMATION message to the network including a list of candidate/ target cell identifiers ranked in order of preference which is the most recent list available from the other radio access technology (e.g. GSM RR) and including the received signal strength for each identified GERAN or UTRAN cell. The MS may include GERAN cells, UTRAN cells or both.
3GPP TS 44.318 subclause 7.8.3:
The MS shall:
- suspend all NAS layer signalling transmissions;
- start the connection establishment to the target radio access technology (e.g. GERAN) by using the contents of the Handover From GAN Command IE. This message carries information about the candidate/ target cell identifier and radio parameters relevant for the target radio access technology;
A MS that is simultaneously operating in GPRS and CS modes over GAN shall follow the procedure as outlined in 3GPP TS 43.055 when it switches to target cell.
NOTE: The requirements concerning the establishment of the radio connection towards the target radio access technology (e.g. GERAN) and the signalling procedure are outside of the scope of this specification.
3GPP TS 44.318 subclause 7.8.4:
Upon successfully completing the handover, the GANC should:
- release all radio resources associated with the GAN connection.
Upon successfully completing the handover, the MS shall:
- switch to target radio access technology (e.g. GERAN) mode i.e. detach the GA-RR entity from the RR-SAP;
- enter GA- RC -REGISTERED state.
NOTE: The release of the GAN radio resources is initiated from the target RAT. The MS may deregister from the GANC (as defined in sub-clause 6.4) after successfully completing the handover. If the MS chooses to deregister from the GANC, it may do so either immediately after successfully completing the handover or after sending the GA-CSR RELEASE COMPLETE message to the GANC in response to the GA-CSR RELEASE message from the GANC.

The network initiates the ciphering mode setting procedure by sending a GA-CSR CIPHERING MODE COMMAND message to the mobile station, indicating whether ciphering shall be used or not, and if yes which algorithm to use.
Additionally, the network may, by the use of the cipher response information element, request the mobile station to include its IMEISV in the GA-CSR CIPHERING MODE COMPLETE message.
Whenever the mobile station receives a valid GA-CSR CIPHERING MODE COMMAND message, it shall, if a SIM is present and considered valid and the ciphering key sequence number stored on the SIM indicates that a ciphering key is available, save information about the ciphering key to use if the MS is later performing Handover from GAN. A valid GA-CSR CIPHERING MODE COMMAND message is defined to be one of the following:
- one that indicates "start ciphering" and is received by the mobile station in the "not ciphered" mode;
- one that indicates "no ciphering" and is received by the MS in the "not ciphered" mode; or
- one that indicates "no ciphering" and is received by the mobile station in the "ciphered" mode.
Other GA-CSR CIPHERING MODE COMMAND messages shall be regarded as erroneous, and a GA-CSR STATUS message with cause "Protocol error unspecified" shall be returned, and no further action taken.
The MS shall also calculate a MAC (Message Authentication Code). The MAC shall be calculated over the following data:
RAND | IMSI
using "HMAC-SHA1-96" algorithm, as specified in [24] with Kc as authentication key.
In the formulas above, the "|" character denotes concatenation. RAND is the 16-octet random number received from the GANC in the GA-CSR CIPHERING MODE COMMAND message. IMSI is the MS IMSI, in the same format as defined for the Mobile Identity IE as defined in [8 / 3GPP TS 44.318 v.6.0.0] i.e. as a variable-length sequence of digits in BCD format (e.g. the IMSI "123456789098765" is encoded as the following octets (in hexadecimal): "21 43 65 87 09 89 67 F5"). Network byte order is used.
The Kc key is the Kc that has been derived during the last authentication. The length of the MAC is 12 octets.
When the appropriate action on the GA-CSR CIPHERING MODE COMMAND message has been taken, the mobile station sends back a GA-CSR CIPHERING MODE COMPLETE message. If the "cipher response" field of the cipher response information element in the GA-CSR CIPHERING MODE COMMAND message specified "IMEISV must be included" the mobile station shall include its IMEISV in the GA-CSR CIPHERING MODE COMPLETE message.

In dedicated mode, the GANC can request a modification of the channel mode, multi-rate configuration, RTP redundancy configuration, sample size, GANC IP address, GANC RTP UDP port and GANC RTCP UDP port used for an active traffic channel.
The channel mode modify procedure allows the network to request the mobile station to modify configuration used for an active channel. The channel mode covers the coding, decoding and transcoding mode as well as the redundancy policy used on the active channel.
This procedure is always initiated by the network.
The network initiates the procedure by sending a GA-CSR CHANNEL MODE MODIFY message to the mobile station.
When the MS has received the GA-CSR CHANNEL MODE MODIFY message, the mobile station modifies the configuration, sets the mode and/or the RTP redundancy configuration for the active channel and then replies by a GA-CSR CHANNEL MODE MODIFY ACKNOWLEDGE message indicating the ordered channel mode.

If the GANC receives a GA-PSR-ACTIVATE-UTC-REQ message from the MS while the network initiated GA-PSR TC activation procedure is in progress, the GANC aborts the network initiated activation procedure and responds to the MS with the GA-PSR-ACTIVATE-UTC-ACK message including the cause indicating successful activation. The message includes GANC IP address and GANC UDP port to be used for the uplink GPRS user data transport.
If the MS receives a GA-PSR-ACTIVATE-UTC-REQ message from the GANC while the MS initiated GA-PSR TC activation procedure is in progress, the MS shall silently discard the request and wait for the acknowledgment related to the MS initiated activation already in progress.
Upon receiving the uplink user data transfer request from the LLC for LLC SAPI 3, 5, 9 or 11 and while the MS GA-PSR is in the GA-PSR-STANDBY state, the MS shall,
- send a GA-PSR-ACTIVATE-UTC-REQ message,
- start timer TU4002,

|
Upon receiving the downlink user data transfer request associated with LLC SAPI 3, 5, 9 or 11 and if there is no GA-PSR TC associated with the specific MS, the GANC allocates the IP address and the UDP port number to be used by the MS for GPRS user data transport and sends a GA-PSR-ACTIVATE-UTC-REQ message to the MS. The GANC also:
- sets downlink packet sequence number to 0 and
- sets the expected uplink packet sequence number to 0
Upon receiving the GA-PSR-ACTIVATE-UTC-REQ message from the GANC, the MS shall verify the following:
- the GA-PSR is in GA-PSR-STANDBY state
- the GA-PSR TC does not exist
- the GPRS service is not suspended
Assuming successful verification, the MS shall allocate UDP port number for the MS GPRS user data transport and store the associated information. In parallel, the MS GA-PSR shall transition to GA-PSR-ACTIVE state and start TU4001 timer. Subsequently, the MS shall send the GA-PSR-ACTIVATE-UTC-ACK message to the GANC with the cause indicating successful activation. The message includes the MS UDP port to be used for the downlink GPRS user data transport.
After the MS has sent the GA-PSR-ACTIVATE-UTC-ACK message, it shall:
- set the uplink packet sequence number to 0 and
- set the expected downlink packet sequence number to 0
When the TU4001 timer expires and if there are no outstanding uplink GPRS user data messages to be transferred, the MS GA-PSR shall send the GA-PSR-DEACTIVATE-UTC-REQ message to the GANC to request the deactivation of the transport channel. In parallel, the MS shall start TU4002 timer to wait for the confirmation.
