The present document is part 14, sub-part 2, of a multi-part deliverable covering Open Service Access (OSA); Mapping of Parlay X Web Services to Parlay/OSA APIs, as identified below: Part 1: “Common Mapping“; Part 2: “Third Party Call Mapping“; Part 3: “Call Notification Mapping“; Part 4: “Short M

15、essaging Mapping“; Part 5: “Multimedia Messaging Mapping“; Part 6: “Payment Mapping“; Part 7: “Account Management Mapping“; Part 8: “Terminal Status Mapping“; Part 9: “Terminal Location Mapping“; Part 10: “Call Handling Mapping“; Part 11: “Audio Call Mapping“; Part 12: “Multimedia Conference Mapping

16、“; Part 14: “Presence Mapping“; Sub-part 1: “Mapping to Presence and Availability Management“ Sub-part 2: “Mapping to SIP/IMS Networks“. NOTE: Part 13 has not been provided as there is currently no defined mapping between ES 202 391-13 10 and the Parlay/OSA APIs. If a mapping is developed, it will b

17、ecome part 13 of this series. The present document has been defined jointly between ETSI, The Parlay Group (http:/www.parlay.org) and the 3GPP. ETSI ETSI TR 102 397-14-2 V1.1.1 (2005-08) 5 1 Scope The Parlay X Web Services provide powerful yet simple, highly abstracted, imaginative, telecommunicatio

18、ns functions that application developers and the IT community can both quickly comprehend and use to generate new, innovative applications. The Open Service Access (OSA) specifications define an architecture that enables application developers to make use of network functionality through an open sta

19、ndardized interface, i.e. the Parlay/OSA APIs. IP Multimedia Subsystem (IMS) is a Core Network architecture for supporting multimedia services via a SIP infrastructure. The present document specifies the mapping of the Parlay X Presence Web Service to SIP/IMS Networks. 2 References For the purposes

27、llowing apply: applications: for Instant Messaging, Push to Talk, or call control and other purposes may become clients of the Presence Web Service NOTE: We assume that these applications belong to a watcher and authenticate to the services in the name of the watcher. identity: representation of a u

28、ser in the real world NOTE: See ES 202 915-14 5, clause 4.4.1. presence attributes: contain information about a presentity NOTE: An attribute has a name and a value and can be supplied by any device, application or network module that can be associated to the presentitys identity. A watcher can obta

29、in attributes only after he has successfully subscribed to them. Examples for attributes are activity, location type, communication means, etc. presence information: set of attributes that characterize the presentity such as current activity, environment, communication means and contact addresses NO

30、TE: Only the system and the presentity have direct access to this information, which may be collected and aggregated from several devices associated to the presentity. subscription: relationship between a watcher and present data NOTE 1: Before a watcher can access the presence data, he has to suscr

31、ibe to it. One possibility the API provides is an end-to-end subscription concept, in which only identities that have accepted a subscription to their presence can be addressed. Subscriptions can be also automatically handled by server policies edited by the presentity or other authorized users. The

32、 service/protocol to manage those policies is out of the scope of the present document. NOTE 2: This definition is not related to the term “subscription“ in ETSI TR 121 905 1. watcher and presentity: We use these names to denote the role of the client connected to the presence services. NOTE: As in

33、Parlay/OSA PAM 5 the watcher and the presentity have to be associated to identities registered to the system, i.e. users, groups of users or organizations. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 102 397-1 3 and the following apply: DMS Data Manipula

39、ns)OKPUBLISHFigure 2 6 Detailed Mapping Information 6.1 Operations 6.1.1 subscribePresence The sequence diagram in clause 5.1 illustrates the flow for the subscribePresence operation. Upon receiving a subscribePresenceRequest message, the Presence web service will issue a SIP SUBSCRIBE message towar

40、ds the watcher presence proxy. The role of the latter is address resolution, authentication of the web service, finding the network of the target presentity, accounting. In this state (S1), the web service expects to receive a SIP ACK message moving to state S2. In this new state (S2), it expects to

41、 receive a SIP NOTIFY PresUp message from the watcher proxy moving to state S3. In order to convey the selected presence attributes to the SIP system, a filter body has to be created in the SIP SUBSCRIBE message according to 4. In case of a group of presentities, the URI of the group specifies wheth

42、er the SIP SUBSCRIBE message is sent to a RLS (resource list server). If the URI specifies a group maintained by the Address List Management Web Service ES 202 391-13 10, then every member residing in a SIP system is addressed individually. 6.1.2 getUserPresence The sequence diagram in clause 5.1 il

43、lustrates the flow for the getUserPresence operation. getUserPresence gets the actual status stored in the Web Service, since the status changes of the presentity are asynchronously sent to it through the SIP NOTIFY PresUp messages. ETSI ETSI TR 102 397-14-2 V1.1.1 (2005-08) 9 6.1.3 startPresenceNot

44、ification The sequence diagram in clause 5.1 illustrates the flow for the startPresenceNotification operation. This operation enables the SIP events received via NOTIFY PresUp to be sent further to the watcher. In case the presence attributes specified in this operation are not the same as in the su

45、bscribePresenceRequest message, the web service reissues a SIP SUBSCRIBE message with a different filter upon receiving the startPresenceNotificationRequest. 6.1.4 endPresenceNotification The sequence diagram in clause 5.1 illustrates the flow for the endPresenceNotification operation. With this ope

46、ration, the service will cease to forward events to the watcher. The subscription remains active. No action occurs towards the SIP system. 6.1.5 statusChanged The sequence diagram in clause 5.1 illustrates the flow for the statusChanged operation. The asynchronous message statusChangedRequest is sen

47、t to the watcher upon receiving a SIP NOTIFY PresUp message from the SIP system, assuming the watcher notification has been previously enabled with the startPresenceNotification operation. 6.1.6 statusEnd This asynchronous message statusEndRequest is triggered by the web service. There is no mapping

48、 to the SIP system. 6.1.7 notifySubscription The sequence diagram in clause 5.1 illustrates the flow for the notifySubscription operation. Upon receiving the first SIP NOTIFY PresUp message from the watcher presence proxy (state S3), the web service issues an asynchronous notifySubscriptionRequest m

49、essage. 6.1.8 subscriptionEnded The sequence diagram in clause 5.1 illustrates the flow for the subscriptionEnded operation. The asynchronous message subscriptionEnded Request is sent to the watcher in case of a negative SIP NOTIFY PresUp message, following a subscription or a timeout. 6.1.9 publish The sequence diagram in clause 5.2 illustrates the flow for the publish operation. The publish operation maps in the web service to a SIP PUBLISH message to be sent to the next
