3GPP Glossaries:  Interfaces / Reference Points
for letter 'P' (3 of 3)

 

Pi

Up       Top

between  S-CSCF
and  Presence Network Agent

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.6 

The S-CSCF may provide IMS-specific presence information (e.g. about IMS registration state). This reference point shall use mechanisms defined for the ISC reference point.


Pk

Up       Top

between  Presence Network Agent
and  GGSN

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.11 

This reference point shall allow the GGSN to report presence relevant events to the Presence Network Agent (such as PDP context activation/de-activation). This reference point is implemented using the mechanisms of the RADIUS interface for reporting of access requests on Gi reference point.


Pl

Up       Top

between  Presence Network Agent
and  GMLC

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.8 

This reference point shall be used by the Presence Network Agent to retrieve location information related to a subscriber (associated with the presentity). This reference point is the interface to GMLC and it is an instance of the Le reference point.


Pp

Up       Top

between  Presence Network Agent
and  PDG

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.13 

This reference point shall allow the PDG to report presence relevant events to the Presence Network Agent (such as tunnel establishment/removal, allocation of the remote IP address for the WLAN UE). This reference point is based on reusing of the Wi reference point.


Pr

Up       Top

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.12 

This reference point shall allow the 3GPP AAA Server to report IP-connectivity related events to the Presence Network Agent (such as WLAN UE attaching/detaching and tunnel establishment/removal). The Pr reference point shall be as much as possible based on mechanisms of existing interfaces.


Pw

Up       Top

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.4 

This reference point shall allow a Watcher application to request and obtain presence information. This interface shall support the transport of presence information under the PIDF format as specified in RFC 3863.


Pwp

Up       Top

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.15 

The Pwp interface is an intra-operator interface. This reference point shall allow all the functionalities provided by the Pw and Pep reference points.


Px

Up       Top

between  Presentity Presence Proxy
and  HSS

see it   here

specified from  Rel-6  in
TS 23.141, clause 4.3.7 

The Px interface is an intra-operator interface. This interface shall assist locating the Presence Server of the presentity. This interface is implemented using the mechanisms defined for the Cx and Dx reference points.
