New issue 644 by EMMartins: Support OMA Service-URI-Template for Presence
Lists
http://code.google.com/p/mobicents/issues/detail?id=644
As in "Implementation Guidelines for OMA Presence SIMPLE v1.1" Section
5.5.1:
"As described in [PRS_RLS_XDM] “Validation Constraints”, the Service URI
for Presence Lists (i.e. the value of the “uri”
attribute of a <service> element in a Presence List document) proposed by
an XDMC when creating a Presence List in the
RLS XDMS must conform to the syntax of the Service-URI-Template parameter
described in [PRS_AC] and [PRS_MO].
It is RECOMMENDED that:
• the Service-URI-Template for Presence Lists have the following structure:
<xui>;pres-list=<id>
where the <xui> and <id> substitution tags are described in [XDM_Core]
“Provisioned XDMC Parameters”.
The reasons for the recommendation include:
• effective use of resources (e.g. access network bandwidth), since the
recommended Service-URI-Template makes it
easier for the XDMC to generate a globally unique Service URI that is
accepted by the RLS XDMS; and
• simplification for the SIP/IP Core network to recognize the Service URI
as a Presence List (e.g. to optimize routing
of Presence List subscriptions).
An example of a Service URI conforming to the recommended
Service-URI-Template is as follows:
sip:[email protected];pres-list=list-a
where the XUI used to generate the Service URI is a SIP URI, as required by
[PRS_RLS_XDM] “Validation constraints”. "
