1 Calling User Identification Presentation
1.1 Definition
Calling User Identification Presentation is a supplementary service to the called user which provides
the calling user's PHS-number, possibly with subaddress information, to the called user.
1.2 Description
1.2.1 General description
When Calling User Identification Presentation (CUIP) is applicable and activated, the network
provides the called user with the number of the calling user at call set-up on all incoming calls.
The calling user number may be accompanied by a subaddress.
The network should be capable of transmitting at least 15 digits[ maximum length of an integrated
services digital network(ISDN) number. In addition, if provided by the calling user, the network
should be capable of transmitting a subaddress.
The network to which the calling user belongs should attempt to ensure that enough digits aretransmitted to enable the called user to return the call, based on the calling number presented.
1.2.2 Specific terminology
None identified.
1.2.3 Qualifications on the applicability to telecommunication services.
This supplementary service is applicable to all telecommunication services.
1.3 Procedures
1.3.1 Provision/withdrawal
CUIP may be provided on a subscription basis or be generally available. CUIP may be withdrawn at
the request of the user or by the network provider for administrative reasons.
1.3.2 Normal procedures
1.3.2.1 Activation/deactivation/registration
CUIP is activated on provision and deactivated on withdrawal. No information needs to be registeredwith the network for the supplementary service.
1.3.2.2 Invocation and operation
The number presented shall unambiguously identify the access of the calling user.

1.3.3 Exceptional procedures
1.3.3.1 Activation/deactivation/registration
None identified.
1.3.3.2 Invocation and operation
There are two cases where the calling user number is not presented to the called user:(1) when the calling user has an arrangement (see definition of Calling User Identification
Restriction) whereby presentation of his number is not allowed; and(2) when the calling user number is not available, i.g. due to interworking with the analogue public
switched telephone network(PSTN).
In such cases no number is presented to the called user, but he shall receive an indication that the
number of the calling user is unavailable.
In case i), the user will be given an indication that the presentation of number is restricted.
In case ii), the user will be given an indication that the number is not available, for example because
of interworking.
1.3.4 Alternative procedures
1.3.4.1 Activation/deactivation/registration
None identified.
1.3.4.2 Invocation and operation
In some cases where a calling user has an arrangement such that presentation of his number is notallowed, there may be certain categories of called user that have the ability to override this restriction
and have the calling number presented. This function is a national option.
Problems may occur when the calling user does not belong to the same network of the called user andin the calling user's network the override category does not exist, while in the called user's network it
does. A problem occurs when a calling user who restricts presentation and assumes that his number isnever presented, makes a call to a called user who is in the override category.
The cases where the override category is applied is a national matter. Depending on bilateralagreement about the application of the override category in country A may or may not deliver thecalling user identification to country B. Agreements are also needed with any transit network.
1.4 Network capabilities for charging
This Recommendation does not cover charging principles.

1.5 Intercommunication considerations
On calls incoming from some non-ISDN or non-PHSs networks, the calling number may be delivered
to the destination PHS network without the ability to indicate whether presentation is allowed or not.
How the PHS network should behave in this case is for further study.
From some other non-ISDN or non-PHSs networks, no calling user number may be available to the
PHS network and therefore, the calling user number cannot be given to the called user who has been
provided with CUIP. In this situation, a “number unavailable” indication, is given to the called user. If
a “number unavailable” indication is given to the called user, the called user will be clearly informedthat the calling user number is not available as a result of network interworking.
As a national option, the originating network shall have the possibility to restrict any information
identifying the calling user from being forwarded to another network. If a destination network
receives a calling user PHS number without any indication of presentation allowed or restricted, thedestination network (host network) will act according to its own rules and regulations.
1.6 Interaction with other supplementary services
1.6.1 Calling User Identification Presentation (CUIP)
Not applicable.
1.6.2 Calling User Identification Restriction (CUIR)
The calling user identification will not be presented if the calling user has an arrangement to inhibit
the presentation of his number to the called user. The only occasion when a user subscribing to CUIP
can take precedence over Calling User Identification Restriction(CUIR) is when the user has anoverride category. This is a national option.
1.6.3 Call forwarding
1.6.3.1 Call Forwarding Unconditional (CFU)
Called user: if subscribed to, the called user can receive the calling user identification of all calls
which have been forwarded.
Forwarded-to users, who have subscribed to CUIP, may receive the calling user's number if thecalling user has not subscribed/invoked CUIR.
1.6.3.2 Call Forwarding on PS Busy (CFB)
Called user: if subscribed to, the called user can receive the calling user identification of all calls
which have been forwarded.
Forwarded-to users, who have subscribed to CUIP, may receive the calling user's number if thecalling user has not subscribed/invoked CUIR.

1.6.3.3 Call Forwarding on No Reply (CFNRy)
Called user: if subscribed to , the called user can receive the calling user identification of all calls
which have been forwarded.
Forwarded-to users, who have subscribed to CUIP, may receive the calling user's number if thecalling user has not subscribed/invoked CUIR.

2 Calling User Identification Restriction
2.1 Definition
Calling User Identification Restriction is a supplementary service offered to the calling party torestrict presentation of the calling party’s PHS-number and subaddress to the called user.
2.2 Description
2.2.1 General description
When Calling User Identification Restriction(CUIR) is applicable and activated, the originating node
provides the destination node with a notification that the calling user's PHS number and any
subaddress information are not allowed to be presented to the called user. In this case no calling user
number s included in the call offering to the called user's installation.
Note- When CUIR is subscribed to, some network providers may not wish to send the originating
identity of the calling customer to network providers.
2.2.2 Specific terminology
None identified.
2.2.3 Qualifications on the applicability to telecommunication services
None identified, i.e. this supplementary service is applicable to all telecommunication services.
2.3 Procedures
2.3.1 Provision/withdrawal
CUIR can be provided on a subscription bases or be generally available.
As a network provider option, CUIR can bee offered with several subscription options. The options
apply separately to each PHS number. Subscription options are summarized below:

Table 2-1/B-SV2.00 Subscription option values
Subscription option
CUIR mode
Default (only for temporary mode)

ValuesPermanent(active for all calls)
Temporary(specified by user per call)
Presentation restricted
Presentation not restricted

It is a network provider option to specify either or both of the above options for all subscribers, forinstance, in an exchange or network.
2.3.2 Normal procedures
2.3.2.1 Activation/deactivation/registration
If subscribed to in the permanent mode, CUIR is always activated. If subscribed to on a temporary
basis, CUIR is activated upon explicit request for the service, or on default, on a particular call and isdeactivated after that call.
2.3.2.2 Invocation and operation
If the called party subscribes to Calling User Identification Presentation and the calling party has
CUIR activated, the called party shall receive an indication that the presentation of the calling party
number is restricted.
2.3.3 Exceptional procedures
2.3.3.1 Activation/deactivation/registration
No exceptional procedures identified.
2.3.4 Alternative procedures
2.3.4.1 Activation/deactivation/registration
No alternative procedures identified.
2.3.4.2 Invocation and operation
Certain countries may define categories of subscribers that have the ability to override thepresentation restriction and have the calling user's PHS number and any subaddress presented(e.g. thepolice).
The ability to have such override category is a national matter.
When a call originates in one PHS network and terminates in another PHS network and CUIR isapplied, the rules and regulations of the destination network(the host network) should apply. For

B-SV2.00-01-TS

example, if the override category is not applicable in the originating network but it is in thedestination network, a call with CUIR applied can still be overridden in the destination network,
whenever information on the calling user is available for this network.
2.4 Network capabilities for charging
This Recommendation does not cover charging principles.
2.5 Interworking requirements
On calls to or via non-ISDNs or non-PHSs, it cannot be assured that a CUIR indication can be carried
to the destination network. As a national option, the originating network shall have the possibility torestrict any information identifying the calling user PHS number without any indication ofpresentation allowed or restricted, the destination network(the host network)will act according to its
rules and regulations.
2.6 Interaction with other supplementary services
2.6.1 Calling User Identification Presentation (CUIP)
The calling user identifications will not be presented if the calling user has an arrangement to inhibit
the presentation of his number to the called party.

is in an override category. This is a national option.
2.6.2 Calling User Identification Restriction (CUIR)
Not applicable.
2.6.3 Call forwarding
2.6.3.1 Call Forwarding Unconditional (CFU)
