CALL:FUNCtion

Function

GSM TA

This command sets/queries the type of connection. This is always set to AUTO for the GSM test application.

GPRS TA

This command sets/queries the type of connection that is used when you use the command CALL:FUNCtion:DATA:START to start a data connection.

If you set this parameter to ETSI Type A, no packet data traffic channel (PDTCH) bursts will be transmitted on the downlink.

Setting this parameter to ETSI Type B (unacknowledged) ensures that one or more downlink (PDTCH) bursts are present, which can be used to loopback data through the uplink. The number of downlink bursts is determined by the setting of the command CALL:(PDTCH|PDTChannel):MSLot:CONFig . The ETSI Type B Acknowledged connection type (ACKB) is almost identical to the ETSI Type B (Unacknowledged) connection type, except that it features an acknowledged downlink. The acknowledged downlink ensures maximum compatibility with different mobile station types.

ETSI Type B (Unacknowledged) or ETSI Type B (Acknowledged) is required if you want to perform BER measurements in active cell mode.

Setting this parameter to BLER ensures that an Agilent proprietary data connection type is used which allows the test set to obtain BLock Error Rate (BLER) measurement reports from the mobile station (see Block Error Rate (BLER) Reports Description ). In addition, the BLER data connection type allows you to perform other GPRS measurements at the same time (except BER and ORFS due to Modulation).

It is recommended you always end the data connection (using CALL:FUNCtion:DATA:STOP ) before changing the data connection type. If you change this parameter while the data connection status is transferring, the data connection will be dropped (changing the data connection status to attached), and an error message will be generated.

GSM/GPRS LA

In addition to the functions of the GPRS TA (above), the GSM/GPRS lab application has the following effects:

• When the data connection type is AUTO (formerly known as IP Data), BER measurements will not be accurate due to synchronization problems. However, BLER measurements are not affected.

EGPRS TA

This command sets/queries the type of connection that is used when you use the command CALL:FUNCtion:DATA:START to start a data connection.

If you set this parameter to ETSI Type A, no packet data traffic channel (PDTCH) bursts will be transmitted on the downlink.

Setting this parameter to ETSI Type B (unacknowledged) ensures that one or more downlink (PDTCH) bursts are present, which can be used to loopback data through the uplink. The number of downlink bursts is determined by the setting of the command CALL:(PDTCH|PDTChannel):MSLot:CONFig . The ETSI Type B Acknowledged connection type (ACKB) is almost identical to the ETSI Type B (Unacknowledged) connection type, except that it features an acknowledged downlink. The acknowledged downlink ensures maximum compatibility with different mobile station types.ETSI Type B (unacknowledged) or ETSI Type B Acknowledged is required if you want to perform BER measurements in active cell mode.

Each of the ETSI test modes are extended with EGPRS header information.

Setting this parameter to BLER ensures that an Agilent proprietary data connection type is used which allows the test set to obtain BLock Error Rate (BLER) measurement reports from the mobile station (see Block Error Rate (BLER) Reports Description ). In addition, the BLER data connection type allows you to perform other GMSK modulated EGPRS measurements at the same time (except Bit Error Rate and ORFS due to Modulation).

Setting this parameter to SRBL ensures that the Switched Radio Block (SRB) Loopback mode is used for the data connection. This connection type is only available in Active Cell operating mode.

It is recommended you always end the data connection (using CALL:FUNCtion:DATA:STOP ) before changing the data connection type. If you change this parameter while the data connection status is transferring, the data connection will be dropped (changing the data connection status to attached), and an error message will be generated.

When the data connection type is AUTO (formerly known as IP Data), BER measurements will not be accurate due to synchronization problems. However, BLER measurements are not affected.

GPRS TA

This command sets/queries whether or not the Logical Link Control (LLC) Frame Check Sequence (FCS) is corrupted in order to establish a BLER mode data connection.

Setting this parameter to VALid ensures that the cyclic redundancy check code within the FCS is valid.

Setting this parameter to CORRupt causes the test set to transmit an invalid FCS to the mobile. This setting may enable some mobiles to establish a BLER mode data connection which would not otherwise be possible with a valid FCS.

This parameter is only applicable when the data connection type is set to BLER using CALL:FUNCtion:CONNection:TYPE BLER.

If you change this parameter while the data connection type is any type other than BLER, the setting has no effect until a new BLER mode data connection is established.

This command along with CALL:FUNCtion:DATA:BLER:POLLing:INTerval provides you with additional control over BLER data connection type settings. This may enable the test set to establish a BLER mode data connection with mobiles which cannot connect under normal conditions.

When the PDU count is set to zero, the test set commands the mobile station to transmit continually as long as there is a connection between the mobile station.

This command sets/queries the type of frame numbering scheme to be used when establishing a data connection.

Changing the frame numbering scheme may enable the test set to establish a data connection with mobiles which cannot connect under normal conditions.

When you set this command to:

• RELative, the test set sends the starting frame number to the mobile as a relative offset from the current frame.
• ABSolute, the test set sends the starting frame number to the mobile as an absolute frame number.
• IMMediate, the test set sends the starting frame number as an immediate assignment.

It is recommended that you should not change this parameter while the data connection status is Starting, as there is no guarantee whether the new setting or the previous setting will be used for the current data connection.

If the type of data connection you want to establish is BLER, the commands CALL:FUNCtion:DATA:BLER:LLC:FCSequence and CALL:FUNCtion:DATA:BLER:POLLing:INTerval may also be helpful in enabling the test set to establish a data connection with mobiles which cannot establish a BLER data connection under normal conditions.

In order to keep backward-compatibility, when the setting is set to OFF in operating modes other than EGPRS test modes, the Demod Type is always Normal. But the BTE report is still not available to reduce the message exchange between processors of the test set. When the setting becomes OFF in EGPRS test modes and BER, BLER or SRB BER measurement is not running, the EGPRS Demod Type Setting reverts to Reduced and EGPRS demodulation is applied only occasionally.
