The Public_user_identity leaf defines zero or more public user identities to which the phone-context parameter value is associated.

• Occurrence: OneOrMore
• Format: chr
• Access Types: Get, Replace
• Values: <A public user identity>

The SS_domain_setting leaf indicates the network operator's preference for the selection of the domain used by the UE when performing supplementary services (SS) setting control for voice services.

• Occurrence: ZeroOrOne
• Format: int
• Access Types: Get, Replace
• Values: 0, 1, 2
  0
  Indicates that the UE only uses the PS domain for SS setting control
  1
  Indicates that the UE only uses the CS domain for SS setting control
  2
  Indicates that the UE uses the PS domain for SS setting control when the PS domain is being used by the UE for voice services, and the UE uses the CS domain for SS setting control when the CS domain is being used by the UE for voice services

The network operator can select the preference for the selection of the domain used by the UE when performing supplementary services (SS) setting control for voice services, according to the domain(s) where the supplementary services are provisioned. For example:

• if the supplementary services are provisioned only in the PS domain, the UE can be restricted to configure only the supplementary services part of the IMS multimedia telephony communication service by setting value "0";
• if the supplementary services are provisioned only in the CS domain, the UE can be restricted to configure only the supplementary services for CS speech by setting value "1"; and
• if the supplementary services are provisioned in both the CS domain and PS domain, then value "2" can be set to restrict the UE to:
  1. configure the supplementary services for CS speech when the UE is using the CS domain for voice services; and
  2. configure the supplementary services part of the IMS multimedia telephony communication service when the UE is using the PS domain for voice services.

The PS_domain_IMS_SS_control_preference leaf provides a means to define the method for which Supplementary Services as defined by TS 22.173 are controlled by the UE when SS setting control is to be invoked over the PS domain.

• Occurrence: ZeroOrOne
• Format: bool
• Access Types: Get, Replace
• Values: 0, 1
  0
  Indicates that the IMS SS setting control for services defined by TS 22.173 is to be invoked using XCAP/Ut as defined by TS 24.623
  1
  Indicates that the IMS SS setting control for services defined by TS 22.173 is to be invoked using SIP-based user configuration as defined by TS 24.238

The UE uses the information stored in the PS_domain_IMS_SS_control_preference leaf either when the SS_domain_setting leaf is set to "0", or when SS_domain_setting is set to "2" and the domain currently used for voice services is the PS domain.

This interior node describes the media type restriction policy.

• Occurrence: ZeroOrOne
• Format: node
• Access Types: Get, Replace
• Values: N/A

The media type restriction policy consists of zero or more media type restriction policy parts. Each media type restriction policy part is described by a child node. A media type is restricted from inclusion in a SDP message according to the media type restriction policy indicated by this interior node, if at least one child node restricts inclusion of the media type in the SDP message. The media type restriction policy does not influence SDP messages exchanged in an IMS emergency call.

This interior node describes the media type restriction policy part.

• Occurrence: ZeroOrMore
• Format: node
• Access Types: Get, Replace
• Values: N/A

The media type restriction policy part consists of a mandatory media type in the Media_type child node and zero or more conditions in child nodes other than the Media_type child node. The media type restriction policy part indicated by this interior node restricts inclusion of a media type in an SDP message if:

1. the media type is indicated in the Media_type child node;
2. the following is true:
   1. this node does not have an IP-CAN child node; or
   2. the following is true:
      1. the SDP message contains an "m=" SDP line of the media type;
      2. the "m=" SDP line is associated with a "c=" SDP line;
      3. the "c=" SDP line indicates an IP address;
      4. the IP address is associated with an IP-CAN bearer; and
      5. the IP-CAN bearer is of an IP-CAN indicated in the IP-CAN child node;
3. the following is true:
   1. this node does not have an ICSI child node; or
   2. the SDP message describes session offered or established by SIP signalling related to an IMS communication service identified in the ICSI child node; and
4. the following is true:
   1. this node does not have a Roaming child node; or
   2. the following is true:
      1. this node has a Roaming child node;
      2. the SDP message contains an "m=" SDP line of the media type;
      3. the "m=" SDP line is associated with a "c=" SDP line;
      4. the "c=" SDP line indicates an IP address;
      5. the IP address is associated with an IP-CAN bearer; and
      6. the UE roams in the IP-CAN of the IP-CAN bearer.

This leaf indicates a restriction applicable for a media type.

• Occurrence: One
• Format: chr
• Access Types: Get, Replace
