Abstract
A system described herein may provide for the prioritization of Session Initiation Protocol ('SIP') messages, transmitted by a User Equipment ('UE'), based on a priority class indicator (“PCP”) included in a registration message (e.g., a SIP REGISTER message) from the UE. The PCI may be included in a contact header, a SIP contact Uniform Resource Identifier (“URI”), and/or some other portion of the registration message. A Universal Integrated Circuit Card (“UICC”) may store information indicating the priority class (e.g., in an Access Control Class (“ACC”) Elementary File (“EF”)). One or more network components, such as a Call Session Control Function (“CSCF”) may prioritize SIP messages from the UE based on the priority class indicator included in the registration message by the UE.
