Similar to OIP and OIR, the TIP and TIR services also have been very common place in legacy networks.
The TIP service enables the calling party to receive the identification information of the remote party from the network. This information is provided to the originating party once the IMS communication has been accepted between the endpoints. The information is delivered regardless of the capability of the handset to process such information at the originating end.
The TIR service provides the terminating party with an option to restrict the identity to be presented to the originating party of the IMS communication. Logically speaking, it is the reverse of what TIP is.
The TIP and TIR services need some support at the handset’s end as well to function properly. Currently the 3GPP release is at 8.3 regarding these services.

OIP and OIR have been around for a long time in the legacy world. So, it is no surprise that they have been standardized as part of the IMS architecture.
Even though supplementary services are call control telephony services, and should logically be the part of the CSCF, but they have been pushed to the IMS application layer in the form of a MMtel server.
The OIP service enables the called party to receive a network generated and trusted identity of the calling user on the screen of the mobile device. The originating user may also present a custom identity to be seen at the called party. The user generated identity is usually screened by the network of the originating user.
The OIR service is invoked when the calling user does not want their identity to be shown to the called party. In such cases, the network of the originating user signals to the network of the called user, to withhold the identity of the calling user.
Both these services are pretty basic in nature, and are being used almost with every mobile phone call we make !
