More Information
Summary:When a user equipment (UE) registers with an Internet Protocol Multimedia Subsystem (IMS), a serving call session control function (S-CSCF) of the IMS can obtain user profile information associated with the UE from a Home Subscriber Server (HSS). The user profile information may include a priority indicator, such as an indication that a user associated with the UE is a Wireless Priority Services (WPS) user or other high priority user. In that situation, the S-CSCF can inform a proxy call session control function (P-CSCF) of the IMS that the user is a WPS user or other high priority user by sending a dedicated priority message to the P-CSCF, separately from sending a registration confirmation message to the P-CSCF.
