The contents of the present document are subject to continuing work within the TSG and may change fo
21、llowing formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented
22、to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the d
23、ocument. Introduction This technical specification gives an overview of the security architecture and defines the security features and security mechanisms for the presence services. Presence services enable the dissemination of presence information of a user to other users or services. A presence e
24、ntity or presentity comprises the user, users devices, services and service components. It is the intention that this platform will enable new services like e.g. enhancement to chat, multimedia messaging, cinema ticket information, the score of a football game and so on. A user has the possibility t
25、o control if her or his information is made available to other users or services. This control is possible to achieve with high granularity e.g. explicitly define which user or users and services have access to presence information. A presentity is a uniquely identifiable entity with the capability
26、to provide the presence information and it has only one principal associated with it. Hence a principal is distinct from all other principals and can be e.g. a human, organisation, program or even a collection thereof. One example of such a relation is when the presentity is a terminal and the princ
27、ipal of the terminal is the subscriber. However, the presence service is based on Public Identities, and consequently it is possible to have several terminals related to the same presentity. A watcher is also a uniquely identifiable entity but with the aim to fetch or request information about a pre
28、sentity. There are access rules that set the rules for how presence information gets available to watchers. Presence information consists of a number of elements or presence tuples as defined in TS 23.141 3 ETSI ETSI TS 133 141 V14.0.0 (2017-04)53GPP TS 33.141 version 14.0.0 Release 141 Scope The pr
29、esent document is the Stage 2 specification for the security requirements, security architecture, security features and security mechanisms for the Presence Service, which includes the elements necessary to realise the requirements in TS 22.141 2 and TS 23.141 3. As far as SIP-based procedures are c
30、oncerned, this specification refers to TS 33.203 4. The main content of this specification is the security for the Ut reference point, which is HTTPbased, as applied in presence services. The present document includes information applicable to network operators, service providers and manufacturers.

43、SCFs as Watcher Presence proxies and Presentity Presence proxies may offer the Presence services on top of the IMS network, see TS 22.141 2. The access security for IMS is specified in TS 33.203 4 ensuring that SIP signalling is integrity protected and that IMS subscribers are authenticated through
44、the use of IMS AKA. The security termination point from the UE towards the network is in the P-CSCF utilising IPsec ESP. A watcher may send a SIP SUBSCRIBE over IMS towards the network, to subscribe or to fetch presence information, i.e., the Presence Service supports SIP-based communications for pu
45、blishing presence information. The presence information is provided by the Presence Server to the Watcher Application using SIP NOTIFY along the dialogue setup by SUBSCRIBE. This traffic is protected in a hop-by-hop fashion as specified in TS 33.210 10 with the access security provided in TS 33.203
46、4. The Presence Server is responsible for managing presence information on behalf of the presence entity and it resides in the presentitys home network. Furthermore, the Presence Server provides a subscription authorization policy that is used to determine which watchers are allowed to subscribe to
47、certain presence information. Prior to accepting the subscription requests from watchers, the presence server attempts to verify the identities of the watchers. Optionally, depending on the implementation, the Presence Server may authenticate an anonymous watcher depending on the Subscription Author
48、ization Policy. A Presence List Server is responsible of storing grouped lists of watched presentities and enables a Watcher Application to subscribe to the presence of multiple presentities using a single SIP SUBSCRIBE transaction. The Presence List Server also stores and enables management of filt
49、ers in the presence list, see figure 1.
