22.2433GPPRelease 17Speech recognition framework for automated voice servicesStage 1TS

SRF-based automated voice services may be provided by the network operator (home or visited) or by third parties. See appendix A for examples of such services.

The administration of the SRF-based automated voice services will be under the control of the network operator. But when decided to do so by the network operator, it should be possible to the third party providers to administer the SRF-based automated voice services them selves through the gateway that they would connect to IMS. In such case, the third party provider performs all the administrative steps and no registration would be required with the network operator.

6.1 Authorization

Authorization for use of SRF-based automated voice services will be under the control of the network operator. It shall require authorization of the connection to IMS.

The network operators can provide automated voice services or they can only provide the network that connects users to SRF-based automated voice services provided by third party application service providers. The network operator shall be able to permit or prevent access to a third party service. This requirement shall be treated as equivalent to allowing or prevent access to some phones numbers (IMS voice sessions) or internet services (domains for example in WAP data access).

The network operator shall be able to administer the authorization of a SRF-based automated voice service on a user basis as well as on a service basis (e.g. to authorize access to all users or prevent access to all users).

It shall be possible for the operator to provide for the user:

– Authorization to access a particular "address" (e.g. 3rd party SRF-based automated voice service)

– Authorization to use a service that the operator authorize access to when the 3rd party operator wishes to rely on the operator to control this access

It shall be possible for the third party provider to authorize usage of its services based on the identity of the user.

6.2 Deauthorization

Deauthorization for use of the SRF-based automated voice services shall be under the control of the network operator as for the authorization described in section 6.1.

6.3 Registration

Authorized SRF-based automated voice service register their address with the IMS upon authorization of the service authorized SRF-based automated voice service can then be reached by the user (by entering address and initiated a SRF session).

6.4 Deregistration

Disconnection from the IMS shall prevent the use of the SRF-based automated voice service. Deregistration may be decided by the third party provider.

6.5 Activation

Once authorized and registered a SRF-based automated voice service is deemed activated as for other IMS services.

6.6 Deactivation

Deactivation shall be done by deregistering the services (operator or service provider initiative) or by refusing to initiate a SRF session (service provider initiative).
