Wireless messaging with high-priority quality-of-service
A wireless User Equipment (UE) generate a Session Initiation Protocol (SIP) message that comprises a SIP header and a user message. The SIP header indicates a priority QoS and the user message indicates a message destination. The wireless UE wirelessly transfers the SIP message to a wireless network and the wireless network transfers the SIP message to a message network. In response to the priority QoS indicated in the SIP header, the message network generates and transfers another SIP message using the priority QoS. The other SIP message comprises another SIP header and the user message.

a wireless User Equipment (UE) generating a Session Initiation Protocol (SIP) message that comprises a P-Access-Network Info (PANI) header and the user message, wherein the PANI header indicates the priority QoS and an establishment cause and the user message indicates the message destination;
the wireless UE wirelessly transferring the SIP message to the wireless network;
the wireless network wirelessly receiving the SIP message from the UE;
the wireless network transferring the SIP message to a message network; and
the message network receiving the SIP message, and in response to the priority QoS and the establishment cause indicated in the PANI header, generating and transferring another SIP message using the priority QoS and the establishment cause, wherein the other SIP message comprises another PANI header and the user message.
2. The method of claim 1 further comprising:
the wireless network receiving the other SIP message that comprises the user message from the message network and wirelessly transferring the other SIP message to another wireless UE that comprises the message destination; and
the other wireless UE wirelessly receiving the other SIP message that comprises the user message.

the wireless network wirelessly receiving the SIP message from the UE comprises using the priority access class.
7. The method of claim 1 wherein:
the wireless UE wirelessly transferring the SIP message to the wireless network comprises using access class 14 ; and
the wireless network wirelessly receiving the SIP message from the UE comprises using the access class 14 .
8. The method of claim 1 wherein:
the establishment cause comprises a priority establishment cause;
the wireless UE wirelessly transferring the SIP message to the wireless network comprises using the priority establishment cause; and
the wireless network wirelessly receiving the SIP message from the UE comprises using the priority establishment cause.
9. The method of claim 1 wherein:
the establishment cause comprises an emergency establishment cause;
the wireless UE wirelessly transferring the SIP message to the wireless network comprises using the emergency establishment cause; and
the wireless network wirelessly receiving the SIP message from the UE comprises using the emergency establishment cause.
10. The method of claim 1 wherein:
the wireless UE comprises a Long Term Evolution (LTE) UE;
the wireless network comprises an LTE network; and
the message network comprises an Internet Protocol Multimedia Subsystem (IMS).
11. A wireless communication system to transfer a user message to a message destination using a priority Quality-of-Service (QoS), the wireless communication system comprising:
a wireless User Equipment (UE) configured to generate a Session Initiation Protocol (SIP) message that comprises a P-Access-Network Info (PANI) header and the user message, wherein the PANI header indicates the priority QoS and an establishment cause and the user message indicates the message destination;
the wireless UE configured to wirelessly transfer the SIP message to the wireless network;
the wireless network configured to wirelessly receive the SIP message from the UE;
the wireless network configured to transfer the SIP message to a message network; and
the message network configured to receive the SIP message, and in response to the priority QoS and the establishment cause indicated in the PANI header, generate and transfer another SIP message using the priority QoS and the establishment cause, wherein the other SIP message comprises another PANI header and the user message.
12. The wireless communication system of claim 11 further comprising:
the wireless network configured to receive the other SIP message that comprises the user message from the message network and wirelessly transfer the other SIP message to another wireless UE that comprises the message destination; and
the other wireless UE configured to wirelessly receive the other SIP message that comprises the user message.
