The Linear TV service is triggered through user interactio

49、n, preset recording instructions, or other means. 2. The ITF initiates a SIP session by sending a SIP INVITE to the P-CSCF (E3i). 3. The P-CSCF initiates a resource reservation request (reservation phase) to the RACF based on the Bandwidth requested in the incoming INVITE. The RACF allocates the default initial bandwidth (S3).The RACF signals that the bandwidth allocation is complete to the P-CSCF (S3). 4. The P-CSCF forwards the INVITE to the S-CSCF.
