EXAMPLE:

The Resource_Allocation_Mode leaf indicates whether UE initiates resource allocation for the media controlled by IM CN subsystem for all IMS sessions not covered by any "ICSI Resource Allocation Mode", when both UE and network can initiate resource allocation.

• Occurrence: ZeroOrOne
• Format: bool
• Access Types: Get, Replace
• Values: 0, 1
  0
  Indicates that the UE attempts to initiate resource allocation for the media controlled by IM CN subsystem.
  1
  Indicates that the UE does not attempt to initiate resource allocation for the media controlled by IM CN subsystem.

In absence of the parameter, UE attempts to initiate resource allocation for the media controlled by IM CN subsystem for all IMS sessions not covered by any "ICSI Resource Allocation Mode", when both UE and network can initiate resource allocation.

The Voice_Domain_Preference_E_UTRAN leaf indicates network operator's preference for selection of the domain to be used for voice communication services by the UE.

• Occurrence: ZeroOrOne
• Format: int
• Access Types: Get, Replace
• Values: 1, 2, 3, 4
  1
  Indicates that the UE does not attempt to initiate voice sessions over the IM CN Subsystem using an E-UTRAN bearer. This value equates to "CS Voice only" as described in TS 23.221.
  2
  Indicates that the UE preferably attempts to use the CS domain to originate voice sessions. In addition, a UE, in accordance with TS 24.292, upon receiving a request for a session including voice, preferably attempts to use the CS domain for the audio media stream. This value equates to "CS Voice preferred, IMS PS Voice as secondary" as described in TS 23.221.
  3
  Indicates that the UE preferably attempts to use the IM CN Subsystem using an E-UTRAN bearer to originate sessions including voice. In addition, a UE, in accordance with TS 24.292, upon receiving a request for a session including voice, preferably attempts to use an E-UTRAN bearer for the audio media stream. This value equates to "IMS PS Voice preferred, CS Voice as secondary" as described in TS 23.221.
  4
  Indicates that the UE attempts to initiate voice sessions over IM CN Subsystem using an E-UTRAN bearer. In addition, a UE, upon receiving a request for a session including voice, attempts to use an E-UTRAN bearer for all the the audio media stream(s). This value equates to "IMS PS Voice only" as described in TS 23.221.

The SMS_Over_IP_Networks_Indication leaf indicates network operator's preference for selection of the domain to be used for short message service (SMS) originated by the UE.

• Occurrence: ZeroOrOne
• Format: bool
• Access Types: Get, Replace
• Values: 0, 1
  0
  Indicates that the SMS service is not to be invoked over the IP networks.
  1
  Indicates that the SMS service is preferred to be invoked over the IP networks.

The Keep_Alive_Enabled leaf indicates whether the UE sends keep alives.

• Occurrence: One
• Format: bool
• Access Types: Get, Replace
• Values: 0, 1
  0
  Indicates that the UE does not send keep alives.
  1
  Indicates that the UE is to send keep alives.

3GPP TS 24.229 describes the normative behaviour for the UE sending keep alives when the Keep_Alive_Enabled leaf indicates that sending keep alives is enabled.

The Voice_Domain_Preference_UTRAN leaf indicates network operator's preference for selection of the domain to be used for voice communication services by the UE.

• Occurrence: ZeroOrOne
• Format: int
• Access Types: Get, Replace
• Values: 1, 2, 3
  1
  Indicates that the UE does not attempt to initiate voice sessions over the IM CN Subsystem using an UTRAN PS bearer. This value equates to "CS Voice only" as described in TS 23.221.
  2
  Indicates that the UE preferably attempts to use the CS domain to originate voice sessions. In addition, a UE, in accordance with TS 24.292, upon receiving a request for a session including voice, preferably attempts to use the CS domain for the audio media stream. This value equates to "CS Voice preferred, IMS PS Voice as secondary" as described in TS 23.221.
  3
  Indicates that the UE preferably attempts to use the IM CN Subsystem using an UTRAN PS bearer to originate sessions including voice. In addition, a UE, in accordance with TS 24.292, upon receiving a request for a session including voice, preferably attempts to use an UTRAN PS bearer for the audio media stream. This value equates to "IMS PS Voice preferred, CS Voice as secondary" as described in TS 23.221.

This leaf applies if a UE utilises the services provided by EPS or GPRS to provide packet-mode communication between the UE and the IM CN subsystem. The Mobility_Management_IMS_Voice_Termination leaf indicates whether the UE mobility management performs additional procedures as specified in TS 24.008 and TS 24.301 to support terminating access domain selection by the network.
