B2BUA, dialog, header, header field, SIP response, SIP request, session: definitions in IETF RFC 3261 [3] apply. incoming initial request: all requests intended to initiate either a dialog or a standalone transaction terminated by the served user incoming communication: communication destined to the served user in progress communication: outgoing or incoming communication for which the initiating request has been forwarded to the terminating UE. outgoing communication: communication outgoing from the user side of the interface supplementary service: see ITU-T Recommendation I.210 [5], clause 2.4. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AS Application Server CB Communication Barring CDIV Communication DIVersion services ECT Explicit Communication Transfer HPLMN Home Public Land Mobile Network HSS Home Subscriber Server IP Internet Protocol ODB Operator Determined Barring SDP Session Description Protocol SIP Session Initiation Protocol UE User Equipment 4 Operator Determined Barring Service Description The network feature Operator Determined Barring (ODB) as specified 3GPP TS 22.041 [11] and in this specification allows a network operator or service provider to regulate access to IM CN subsystem services, by the barring of certain categories of incoming or outgoing communications, the barring of certain categories of roaming and the barring of certain categories of supplementary services configuration and invocation. When barring of an incoming or outgoing category of communications is configured all in progress communications belonging to that category are released. The SIP related procedures for support of ODB of Communication Barring are realized in an Application Server (AS) as defined in 3GPP TS 24.229 [2], which depending on the use case, is to be provided on the originating side or the terminating side. The SIP related procedures for support of ODB of the SIP based configuration of a supplementary service, as defined in 3GPP TS 24.238 [8], are realized by the AS which provides the function of SIP based configuration for that supplementary service. ETSI 3GPP TS 24.315 version 11.0.0 Release 11 7 ETSI TS 124 315 V11.0.0 (2013-01) The XCAP related procedures for support of ODB of the XCAP based configuration of a supplementary service, as defined in 3GPP TS 24.623 [9], are realized by the AS which provides the function of XCAP based configuration for that supplementary service. ODB based barring is applied to a subscription by administrative action in the HSS. In order to get the information about the ODB settings for a subscriber an AS can subscribe to notification on such changes via Sh interface as specified in 3GPP TS 29.329 [12]. The HSS contains the ODB categories that apply to the subscriber. The URIs for premium numbers for entertainment, the URIs for premium numbers for information and the conditions for operator specific categories are locally configured in the AS providing the ODB services. It shall be possible for the operator to use patterns and regular expression to configure the URIs for premium numbers in the AS. ODB categories cannot be configured by the user. 5 Barring of Communication 5.1 Barring of outgoing Communication 5.1.1 General Barring of outgoing communication is invoked in the AS performing ODB service. Barring of outgoing communication includes one of the following categories: - barring outgoing communication; - barring outgoing international communications; - barring outgoing international communications except those directed to the home PLMN country; or - barring of outgoing communications when roaming outside the home PLMN country; and one or more of the following categories: - barring of outgoing Premium Rate Communications (Information); - barring of outgoing Premium Rate Communications (Entertainment); - barring of outgoing Premium Rate Communications (Information) when roaming outside the home PLMN country; or - barring of outgoing Premium Rate Communications (Entertainment) when roaming outside the home PLMN country. and one or more of the following categories: - when registered in the HPLMN, Operator Specific Barring (Type 1); - when registered in the HPLMN, Operator Specific Barring (Type 2); - when registered in the HPLMN, Operator Specific Barring (Type 3); or - when registered in the HPLMN, Operator Specific Barring (Type 4). Editor"s Note: Blocking of Premium Rate Communications for roaming subscriber requires further study. ETSI 3GPP TS 24.315 version 11.0.0 Release 11 8 ETSI TS 124 315 V11.0.0 (2013-01) 5.1.2 Procedures in the Application Server The AS providing the ODB service shall operate as a routeing B2BUA as specified in subclause 5.7.5 of 3GPP TS 24.229 [2]. An AS providing the ODB service and rejecting a request shall operate as a terminating UA, as specified in subclause 5.7.2 of 3GPP TS 24.229 [2]. On reception of an initial SIP INVITE request or SIP MESSAGE request initiated by the UE an AS providing the ODB service needs to determine whether ODB is applied to the SIP request. In order to do so the AS providing the ODB service shall: 1) identify the served user as specified in 3GPP TS 24.229 [2] for communication initiated by the UE; 2) determine whether the subscription profile for the served user contains ODB categories as listed in subclause 5.1.1; and 3) use the rules defined in subclause 5.1.3 to determine whether any of the categories apply to the communication. When a barring category applies to a communication, the AS shall either: 1) reject the SIP request, and send an indication to the originating UE by sending a SIP 603 (Decline) response. In addition, based on configuration prior to terminate the communication the AS can provide an announcement to the originating user. The procedure of invoking an announcement is described within 3GPP TS 24.628 [6]; or 2) forward the SIP request to a pre-configured destination using normal SIP procedures as defined in 3GPP TS 24.229 [2]. Editor"s Note: How the AS determines the action to be performed for an outgoing call (i.e. rejection vs forwarding to pre-defined destination is FFS. Also, the level of granularity for configuration of action for the case where a request is barred requires further study. When a new barring category is set for a user, the AS providing the ODB shall determine whether the category applies to any communication of the served user using the rules defined in subclause 5.1.3. When a barring category applies to a communication, the AS providing ODB shall: 1) if two dialogs have been established, then simultaneously send a SIP BYE request for both dialogs managed by the AS, as specified in subclause 5.7.5.3 of 3GPP TS 24.229 [2]; or 2) if a communication is currently being established, then simultaneously send a SIP 603 (Decline) response to the served user and a SIP CANCEL request towards the called user, as specified in 3GPP TS 24.229 [2]. NOTE: In order to get the information about the ODB settings for a subscriber an AS subscribes to notification on such changes via Sh interface as specified in 3GPP TS 29.329 [12]. 5.1.3 Determining whether a category applies to a communication In order to determine whether an ODB category applies for a communication the following applies: 1) outgoing communication: this evaluates to true for all outgoing communication. 2) outgoing international communications: this evaluates to true when the request URI of the outgoing SIP request: a) corresponds to a telephone number, i.e. a SIP URI with a "user" URI parameter set to "phone" or a tel URI; and b) does not point to a destination served by a network within the country where the originating user is located when initiating the call. 3) outgoing international communications except those directed to the home PLMN country: this evaluates to true when the request URI of the outgoing SIP request: a) corresponds to a telephone number, i.e. a SIP URI with a "user" URI parameter set to "phone" or a tel URI; b) does not point to a destination served by a network within the country where the originating user is located when initiating the call; and ETSI 3GPP TS 24.315 version 11.0.0 Release 11 9 ETSI TS 124 315 V11.0.0 (2013-01) c) does not point to a destination served within the served users home network. 4) outgoing communications when roaming outside the home PLMN country: this evaluates to true when the served user is registered from an access network other than the served user home network and when the access network is outside the home PLMN country. NOTE: Whether the served user is registered from another network then the served users home network can be determined from the P-Visited-Network-ID header field specified in IETF RFC 3455 [x] and the P- Access-Network-Info header field specified in IETF RFC 3455 [x] both are provided during the registration process, see 3GPP TS 24.229 [2], subclause 5.7.1.3. 5) outgoing Premium Rate Communications (Information): this evaluates to true when the canonical form of the request URI of the outgoing SIP request matches an entry in the locally configured list of URIs for premium rate communications for information. 6) outgoing Premium Rate Communications (Entertainment): this evaluates to true when the when the canonical form of request URI of the outgoing SIP request matches an entry in the locally configured list of URIs for premium rate communications for entertainment. 7) outgoing Premium Rate Communications (Information) when roaming outside the home PLMN country: this evaluates to true when a) the canonical form of the request URI of the outgoing SIP request matches an entry in the locally configured list of URIs for premium rate communications for information; and b) the served user is registered from an access network other than the served user home network and when the access network is outside the home PLMN country. 8) outgoing Premium Rate Communications (Entertainment) when roaming outside the home PLMN country: this evaluates to true when a) the canonical form of the request URI of the outgoing SIP request matches an entry in the locally configured list of URIs for premium rate communications for entertainment; and b) the served user is registered from an access network other than the served user home network and when the access network is outside the home PLMN country. 9) when registered in the HPLMN, Operator Specific Barring (Type 1): this evaluates to true when the request matches the locally configured conditions for operator specific barring type 1. 10) when registered in the HPLMN, Operator Specific Barring (Type 2): this evaluates to true when the request matches the locally configured conditions for operator specific barring type 2. 11) when registered in the HPLMN, Operator Specific Barring (Type 3): this evaluates to true when the request matches the locally configured conditions for operator specific barring type 3. 12) when registered in the HPLMN, Operator Specific Barring (Type 4): this evaluates to true when the request matches the locally configured conditions for operator specific barring type 4. The Operator specific barring definition for type 1, type 2, type 3, and type 4 is locally configured in the AS providing the ODB service. For operator specific barring the criteria that can be used by the operator to define conditions that are used to determine whether the category applies may be based on any signalling information from the incoming request. Examples of such criteria are: 1) destination type e.g. international numbers or specific numbers; 2) media used in the communication, e.g. audio, video, or text. When any of the items 1) to 12) evaluates to true then the ODB category applies for a communication. 5.2 Barring of incoming Communication Barring of incoming communication is invoked in the AS performing the ODB service. Barring of incoming communication includes one of the following categories: ETSI
