3GPP TS 27.007 V6.3.0 (2003-

06)

Release 6

Set command controls parameters for transparent HSCSD calls in GERAN. Changing them during a call does not affect

the current call.

NOTE: In UTRAN, values set with this command are not needed. The only applicable parameter is <SPEED>,

which is set with +CBST command.

Defined values

<wRx>: integer type; wanted amount of receive timeslots. Default value 0 indicates that TA shall calculate a proper

value from currently selected fixed network user rate (<speed> subparameter from +CBST command) and

<codings>: a sum of integers each representing a channel coding that is accepted for transparent HSCSD calls.

Default value 0 indicates that all supported codings are accepted (refer +CHSD command for other values)

Implementation

Mandatory when transparent HSCSD implemented.

This command is not applicable to UTRAN single mode UE.

Description

Set command controls parameters for non-transparent HSCSD calls. In GERAN, changing <topRx> or <codings>

value during a call does not affect the current call. In GERAN, changing of <wAiur> or <wRx> affects the current call

only if <topRx> was non-zero when call was established.

Defined values

<wAiur>: integer type; wanted air interface user rate. Default value 0 indicates that TA shall calculate a proper

value from currently selected fixed network user rate (<speed> subparameter from +CBST command),

<codings>, and <wRx> (or <maxRx> from +CHSD command if <wRx>=0). Other values:

1 9600 bps

2 14400 bps

3 19200 bps

4 28800 bps

5 38400 bps

6 43200 bps

7 57600 bps

<wRx>: integer type; wanted amount of receive timeslots. Default value 0 indicates that TA shall calculate a proper

value from currently selected <wAiur> and <codings>. This parameter is not applicable to UTRAN single

mode UE.
