Call Control
Precondition and Initiation
Channel combination supported is defined in section Channel Activation
above.
This function is applicable for:
•
SAPI-0 on SDCCH and FACCH
•
SAPI-3 links on SDCCH, SACCH/T and SACCH/M
The function is initiated when the RBS receives an I-frame from MS.
Description
The following procedure is used when the MS sends a transparent layer
3 message to RBS. The message is forwarded to the BSC. The message
is sent through the RBS on the layer 2 link (the RBS is not affected by
the message).
The RBS receives an I-frame containing the layer 3 message. When the
message is received, an acknowledge (RR-frame) is sent back to the
MS. RBS sends a Data Indication message to BSC. The message
contains the received transparent layer 3 message from MS.
The message is in this case sent from mobile to network (BSC). One
example when this is used is for sending an SMS-message to another
subscriber.

Figure 93 Transparent message reception
Transparent transmission in acknowledge mode requires that multiframe
mode /GSM 08.58:3.1,3.2/ has been established. With multiframe mode
means that an answer is needed. In this case an RR-frame (receiver
ready) is sent back as a confirmation to the MS.
20.13 SACCH Info Modify
Purpose
To modify the SACCH information on an individual channel. The
information from RBS is filtered so the unwanted data is removed.
Precondition and initiation
Channel combinations supported are defined in section Channel
Activation above.
