Handover
Handover
A handover is similar to roaming, but occurs during an
ongoing call. A handover normally takes place “in the
background”, without disrupting the call (seamless
handover).
IPEI
International Portable Equipment Identity
• 13-digit identification code for PPs
• Example: 00019 0592015 3
(the final digit is the checksum).
• The code is represented in decimal form.
• This code is globally unique.
PARK
Portable Access Rights Key
Access code for the Portable Part. This code determines
whether a PP can access a particular DECT system. Used
for unique selection of the system at handset
enrolment/subscription time. Provided with the Aastra
OMM Activation Kit and unique to each SIP-DECT
deployment.
Roaming
Roaming
While in motion, the PP performs ongoing measurements
to determine which RFP is best received. The one that can
be best received is defined as the active RFP. To prevent
the PP from rapidly switching back and forth between two
RFPs that have similar signal strength, certain threshold
values are in effect.
