Call Control
This function is initiated when the RBS receives a SACCH INFO
MODIFY from BSC.
Description
This procedure is used by the BSC to modify the SACCH filling
information (System Information) sent on an individual SACCH
channel. For this purpose, the RBS receives a SACCH INFO MODIFY
message from BSC. The SACCH filling information as given in the
SACCH INFO MODIFY message shall be used on the indicated
channel until the channel is released or the information is changed by
another SACCH INFO MODIFY message.
The SACCH is used both uplink and downlink. On the uplink, the MS
sends measurements on its own RBS (signal strength and quality) and
neighbouring RBS (signal strength). On the downlink, the MS receives
information concerning what transmitting power to use.
20.14 LAPDm
Purpose
To provide a reliable signalling link.
Precondition and initiation
Channel combinations supported are defined in section Channel
Activation above.
LAPDm supports two modes of operation:
• unacknowledged
• acknowledged
Both SAPI-0 and SAPI-3 are supported; establishment of SAPI-3
requires that SAPI-0 is established.
SAPI-0
SAPI-0 is used for Call Control, Mobility Management and Radio
Resource Management Signalling. The following channels are
supported:
BCCH + CCCH Downlink. Unacknowledged mode is
supported.
SDCCH Acknowledged and unacknowledged
modes are supported.
FACCH Acknowledged and unacknowledged
modes are supported.
SACCH/C Unacknowledged mode is supported
SACCH/T Unacknowledged mode is supported.
SACCH/M Unacknowledged mode is supported.
