22.0973GPPMultiple Subscriber Profile (MSP) Phase 2Release 17Service descriptionStage 1TS

The profile used when a supplementary service is invoked will be subject to the charging principles and invocation requirements relevant to that supplementary service. The service provider may decide which profiles to charge for the service provision.

6.1 Line Identification Services

The profile in use for the incoming or outgoing call shall be used for the line identification services.

The Line Identification services will be provisioned on a per subscriber basis. If provisioned, the Line Identification services shall apply over all profiles.

6.2 Call Hold (HOLD)

The HOLD service can only be invoked if the profile for that active call has the HOLD service provisioned.

6.3 Call Waiting (CW)

CW for an incoming call can only be invoked if the profile for the ongoing call has the CW service provisioned and active although the incoming call may be on any profile.

6.4 Call Forwarding

Call Forwarding will be available to the subscriber per-profile. An operator specific control procedure may be used by the subscriber to control the call forwarding service.

The subscriber shall be able to forward calls to from one profile to another profile.

6.5 Multi Party Service (MPTY)

The MPTY service can only be invoked or an MPTY call controlled or extended if MPTY is provisioned for the served subscriber for each profile(s) associated with the MPTY call leg(s).

6.6 Closed User Group (CUG)

An MO call shall be treated according to the rules of the CUG service if CUG is provisioned for the selected profile. An MT call shall be treated according to the rules of the CUG service if CUG is provisioned for the profile defined by the called MSISDN.

6.7 Advice of Charge (AoC)

If subscribed to, AoCI or AoCC shall be applicable to the selected profile. Each profile shall have a separate meter (ACM) and a separate upper limit (ACMmax) when AoCC is subscribed. There shall be an overall meter for all profiles, with its own upper limit for AoCC if subscribed. For normal operation both the individual meter applicable to the selected profile and the overall meter shall be incremented.

When roaming to a non-supporting network, only the overall meter shall be incremented.

6.8 Call Barring

Call Barring will be available to the subscriber per-profile. An operator specific control procedure may be used by the subscriber to control the call barring service.

ECT can only be invoked if the service is provisioned for each profile which governs a call leg to be joined by the ECT service.

6.10 CCBS

The CCBS service shall be provisioned per profile. The option not to be a target of CCBS requests shall also apply per profile. When the subscriber is informed of a CCBS recall, the profile in use when the CCBS request was activated shall be used for the CCBS call. If the subscriber activates a CCBS call request on a profile that is not the default profile and subsequently moves to a network not supporting MSP Phase 2, then if the CCBS recall matures, the corresponding CCBS request shall be suspended until the subscriber next registers on a network supporting MSP Phase 2.

The limit to the number of outstanding CCBS requests that can be activated by the subscriber shall apply regardless of the number of profiles.
