(3) The SIP AS modifies the P-Asserted-Identity field and adds the user name and position information.
(4) And encapsulating the P-Asserted-Identity field to the INVITE message, sending the INVITE message back to the CSCF, and continuing to perform the subsequent processes.
(5) At the called user side, CSCF inquires iFC rule and sends INVITE to SIP AS network element.
(6) And the SIP AS performs fuzzy query of a longest matching algorithm through the number of the calling user and queries the user organization architecture information.

Specifically, as shown in fig. 1, the calling subscriber sends out an INVITE message (call initiation signaling). After receiving the INVITE, the IMS CSCF network element forwards the message to the SIP AS, and the SIP AS checks the calling number in the signaling, and if the user name information is queried, adds the information to the P-Asserted-Identity field (for convenience of explanation, the service flow of the MMTel AS and SBC is omitted in the figure).
And after receiving the INVITE message, the called CSCF forwards the INVITE message to a called SIP AS, and the SIP AS checks the calling and called information of the user and modifies the extension field X-Unit and the X-destination field.
After receiving the INVITE message, the SIP terminal parses out the P-Asserted-Identity, X-Unit and X-deparatment fields, and displays them on the screen in a hierarchical manner.
