OCMS Parlay X Web Services  6-1

This chapter describes OCMS support for the Parlay X 2.0 Presence Web services 
interfaces for developing applications. The Web service functions as a Presence 
Network Agent which can publish, subscribe, and listen to notifies on behalf of the 
users of the Web service. This chapter contains the following sections:

OCMS provides support for Part 14 of the Parlay X Presence Web Service as defined in 
the Open Service Access, Parlay X Web Services, Part 14, Presence ETSI ES 202 391-14 
specification. The OCMS Parlay X Web service maps the Parlay X Web service to a 
SIP/IMS network according to the Open Service Access, Mapping of Parlay X Web 
Services to Parlay/OSA APIs, Part 14, Presence Mapping, Subpart 2, Mapping to 
SIP/IMS Networks, ETSI TR 102 397-14-2 specification.

The presence Web service communicates directly with IMS presence network elements 
using the SIP/SIMPLE protocol interface, and uses the JSR-32 UAC framework to 
communicate with the SIP network.

The HTTP server that hosts the presence Web service is a Presence Network Agent or 
a Parlay X to SIP gateway.

Due to the synchronous nature of the Web service, to receive a 

callback from the Web service the client must implement the Web 
service callback interface. For presence, the required interface is the 
PresenceNotification

 interface described in Open Service Access, 

Parlay X Web Services, Part 14, Presence ETSI ES 202 391-14. 

Because this implementation is not common or practical for most Web 
service architectures, the PresenceNotification interface is not 
currently supported.
