3-188 AT Commands Reference Manual June 30, 2008
The following table provides definitions for EFEM-related terms.Table 3-122:EFEM Parameters
Abbreviation/Term Description
2bis Binary information telling wh ether the ext_ind bit in the SysInfo 2 message (sent
by the serving cell in idle mode) indicates that the network is sending a 2bis
message.
2ter Binary information telling whether the 2TI bit in the SysInfo 3 message (sent by
the serving cell) indicates that the network is sending a 2ter message.
5bis Binary information telling wh ether the ext_ind bit in the SysInfo 5 message (sent
by the serving cell in dedicated mode) indicates that the network is sending a 5bis
message.
5ter Binary information indicating whether a 5ter message has been decoded on the
SACCH of the serving cell.
Access class GSM access control class, represented in hexadecimal.
ATT flag Bit that allows or prohibits IMSI attach/detach procedures (from SI 3).
Attach state Either states that the mobile is not camped (in which case it can be either attached
and out-of-coverage, or just not attached), or indicates whether the mobile is
IMSI-attached, GPRS attached, or combine-attached (that is, both IMSI- and
GPRS-attached).
Avarage throughput Average LLC or RLC throughput for the current TBF in kilobits per second.
Throughput is calculated and displayed in the following format: ddd.ff (kbps).
The nine Most Significant Bits provide the kbit/s part of the calculation
(ddd<511); The seven Least Significant Bits provide the decabit/s part (ff<99).
Throughput is calculated as follows: throughput = kbps*1000 + dbps*10.
Warning: LLC throughput counts repeated data as transmitted data, whereas RLC
throughput does not. Note that: the RLC/LLC data flow rates do not take headers
into account; throughput refers to the useful data flow rate.
(P)BCCH ARFCN for
serving cell ARFCN of the serving cell, for either its BCCH in idle and packet/idle modes, or
its PBCCH in packet idle mode (when a PBCCH is present in the cell).
Beacon carrier BC for BCCH. PB for PBCCH.
BS_AG_BLKS_RES Number of paging blocks reserved for AGCH (and not PCH) on the serving cell.
This value (between 0 and 7) is broadcast on System Info 3.
BS_PA_MFRMS Number of 51-frame multiframes between two consecutive paging blocks (on
CCCH). This value (between 2 and 9) is broadcast on System Info 3.
BSIC Base Station Identity Code - The value is represented by an octal format.
C1 The path loss criterion. This is used in cell selection and reselection.
C2 The reselection criterion, which is used only in cell reselection.
C31 GPRS signal-level threshold criterion for reselection, indicating whether or not to
consider a hierarchical reselection.
C32 GPRS cell-ranking criterion for reselection, used to select among cells that have
the same priority.
CBA or CBA2 Cell Bar Access (from System Info 1, 2, 2bis, 3, 4).
CBQ/EXC ACC Cell Bar Qualify. Broadcast on System Info 3 rest octets and 4 rest octets.
