ps (Packet Switched) - All data and control
activities that involve packet services. SRVCC is also mapped to this
traffic-type as the voice is carried using PS service. PS traffic type is
further qualified using a set of QCI values or ARP values or APN profile names.
These qualified entries are only used for paging triggered by S11 Downlink Data
Notifications or Create Bearer Request or Update Bearer Request
Optionally, define the APN Profile for PS traffic:
is an alphanumeric string of size 1 to 64.
The MME supports paging profile selection based on APN. A
maximum of four APN profiles can be configured per precedence using this
When heuristics paging is enabled, the
MME selects the paging profile based on the APN profile, if paging-profile with
matching APN profile name is fetched from the APN information corresponding to
the EBI received in DDN is configured in the paging-map. If the incoming DDN
does not have the EBI information then the APN information is received from the
bearers stored in the MME for the UE. If multiple APN information is available,
then the mapping with the highest precedence is picked. MME warns the user of
duplicate APN profile names in a given entry. The same APN profile name cannot
be configured with more than one precedence level.
Optionally, define the ARP priority based paging for PS traffic
type in the paging-map:
The allowed ARP value " arp_value " is an integer from 1 through 15.
Optionally, define the QoS Class Identifier (QCI) value for this
The QCI values can be either standard or non-standard. The
qci_value is an integer from 1 through 9, 65, 66, 69, 70 (standard values)
and from 128 up to 255 are non-standard values.
QCI qualified entries can only be used for paging triggered by
Downlink Data Notifications received on S11. If the incoming DDN contains EPS
Bearer ID (EBI) information, the QCI corresponding to that PDN is used to find
the appropriate 'ps qci xx' entry and its configured paging-profile.
If there are multiple EBIs included in the DDN the mapping entry
with highest precedence is selected.
If no QCI specific mapping exists, or if the incoming DDN does
not have the EBI information then the qci corresponding to the bearers stored
in MME for the UE shall be used to find the appropriate 'ps qci xx' entry and
its configured paging-profile. The MME warns the user of duplicate QCI values
in a given entry, same QCI values cannot be configured with more than one
signaling [ detach |
]: UE level
signaling requests. This traffic can be optionally qualified according to the
following sub-traffic types:
detach: Paging requests triggered due to UE
triggered in response to an IDR event, such as receiving an IDR Request.
(Location Services) – Paging requests triggered due to Positioning Requests
coming from SMLC over SLs interface. Mobile Terminated Location Requests
arriving on SLg interface can also trigger paging if UE is in IDLE state, and
are included in this sub-traffic type.
node-restoration: Paging requests triggered due to
node restoration (for example, due to P-GW Restart Notification (PRN)). By
default, no precedence is assigned to node restoration signaling traffic. The
MME treats node restoration paging with the least priority.
sub-traffic-type is not configured then paging-profile configured for signaling
(with no sub traffic-type qualification) shall be applied. If no such entry
exists then default-heuristics based paging behavior is applied.
