A Session Initiation Protocol (SIP) server transfers a WPS authorization code to a WPS communication device. The WPS communication device transfers a WPS SIP message to a SIP server. The WPS SIP message has the WPS authorization code and a WPS session request. The SIP server authorizes the WPS SIP message based on the WPS authorization code. When the WPS SIP message is authorized, the SIP server system identifies network addressing based on the WPS session request. The SIP server system transfers a response message to the WPS communication device that identifies the network addressing. The WPS communication device wirelessly transfers WPS data over the WPS session using the network addressing. ## Claims ### Claim 1 A method of operating a wireless data communication network to serve Wireless Priority Service (WPS) communications, the method comprising: a Proxy Call State Control Function (P-CSCF) Session Initiation Protocol (SIP) server system transferring a WPS authorization code; a WPS communication device wirelessly receiving the WPS authorization code; the WPS communication device wirelessly transferring a WPS SIP message having the WPS authorization code and a WPS session request; the P-CSCF SIP server system receiving the WPS SIP message and authorizing the WPS SIP message based on the WPS authorization code, and when the WPS SIP message is authorized, the P-CSCF SIP server system identifying network addressing based on the WPS session request and transferring a response message that identifies the network addressing; and the WPS communication device wirelessly receiving the response message and wirelessly transferring WPS data over the WPS session using the network addressing. ### Claim 2 (depends on 1) The method of claim 1 further comprising the P-CSCF SIP server system authorizing the WPS SIP message based on a Time-To-Live (TTL) for the authorization code. ### Claim 3 (depends on 1) The method of claim 1 further comprising the P-CSCF SIP server system adding a WPS Resource Priority Header (RPH) to the WPS SIP message when the WPS SIP message is authorized. ### Claim 4 (depends on 1) The method of claim 1 further comprising the P-CSCF SIP server system adding a Quality-of-Service (QoS) level to the WPS SIP message based on the authorization code. ### Claim 5 (depends on 1) The method of claim 1 further comprising the P-CSCF SIP server system adding a Quality-of-Service (QoS) level to the WPS SIP message based on an identifier for the wireless communication device. ### Claim 6 (depends on 1) The method of claim 1 wherein the WPS SIP message does not contain a *272 dialing prefix. ### Claim 7 (depends on 1) The method of claim 1 wherein the WPS session comprises voice conferencing. ### Claim 8 (depends on 1) The method of claim 1 wherein the WPS session comprises video conferencing. ### Claim 9 (depends on 1) The method of claim 1 wherein the WPS session comprises data messaging. ### Claim 10 A wireless data communication network to serve Wireless Priority Service (WPS) communications comprising: a Proxy Call State Control Function (P-CSCF) Session Initiation Protocol (SIP) server system configured to transfer a WPS authorization code; a WPS communication device configured to wirelessly receive the WPS authorization code and wirelessly transfer a WPS SIP message having the WPS authorization code and a WPS session request; the P-CSCF SIP server system configured to receive the WPS SIP message and authorize the WPS SIP message based on the WPS authorization code, and when the WPS SIP message is authorized, the P-CSCF SIP server system is configured to identify network addressing based on the WPS session request and transfer a response message that identifies the network addressing; and the WPS communication device configured to wirelessly receive the response message and wirelessly transfer WPS data over the WPS session using the network addressing. ### Claim 11 (depends on 10) The wireless data communication network of claim 10 wherein the P-CSCF SIP server system is further configured to authorize the WPS SIP message based on a Time-To-Live (TTL) for the authorization code. ### Claim 12 (depends on 10) The wireless data communication network of claim 10 wherein the P-CSCF SIP server system is further configured to add a WPS Resource Priority Header (RPH) to the WPS SIP message when the WPS SIP message is authorized. ### Claim 13 (depends on 10) The wireless data communication network of claim 10 wherein the P-CSCF SIP server system is further configured to add a Quality-of-Service (QoS) level to the WPS SIP message based on the authorization code. ### Claim 14 (depends on 10) The wireless data communication network of claim 10 wherein the P-CSCF SIP server system is further configured to add a Quality-of-Service (QoS) level to the WPS SIP message based on an identifier for the wireless communication device. ### Claim 15 (depends on 10) The wireless data communication network of claim 10 wherein the WPS SIP message does not contain a *272 dialing prefix. ### Claim 16 (depends on 10) The wireless data communication network of claim 10 wherein the WPS session comprises voice conferencing. ### Claim 17 (depends on 10) The wireless data communication network of claim 10 wherein the WPS session comprises video conferencing. ### Claim 18 (depends on 10) The wireless data communication network of claim 10 wherein the WPS session comprises data messaging.
