Abstract
An Internet Protocol Multimedia Subsystem (IMS) receives a media session invite having a Wireless Priority Service (WPS) prefix over a non-Long Term Evolution (LTE) network for a User Equipment (UE). The IMS identifies the WPS prefix and adds a Resource Priority Header (RPH) indicating that the media session invite is for a WPS call. The IMS transfers an authentication request to a WPS Application Server to authenticate the UE for the WPS call based on a UE identifier and receives an authentication response indicating that the UE is authenticated. The IMS determines that the media session invite was transferred over the non-LTE network and transfers an instruction to the UE indicating that the UE should re-originate the media session invite over the LTE network. The UE receives the instruction and transfers the media session invite having the WPS prefix to the IMS over the LTE network.
