a reasonable price. This method allows you to define different module behaviour in Home
network, Roaming network and unknown operator areas. See Figure 45 below for details.
Profile 1 is configured for home network. Data acquisition and send intervals are quite
frequent here. To make profile use effective, it is wise to set more optimized parameters in
roaming profile (Profile 2) – this usually includes larger coordinate recording intervals, packets
with greater number of coordinates sending, and in some cases GPRS context available only for a
certain time interval. Profile 3 can either contain operator codes (rarely used) or have an empty
list. Profile 4 is not used (profile 4 can only be used when FMB630 encounters a 'panic' priority
event (see Chapter 7)
In the example (Figure 45) FMB630 connects to operator with code 24702. It checks profile
1 operator list, but there is only one operator code entered which does not mach. Then it checks
profile 2 operators list. This code is entered there, so FMB630 switches to profile 2.
If there are no operator codes entered in all profiles after operator search task FMB630 will
check all 3 profiles and won’t find any operators in any list. In such a case, FMB630 will switch to
profile 3. Note that before switching to profile 3, the device closes the GPRS session.
Operator search is performed every 15 minutes. If no operators are entered in
any profile it can have influence on GPRS sessions. IF GPRS sessions are
attaching/detaching every 15 minutes it means configuration of FMB630 is
performed incorrectly.
