FIG. 2 illustrates an exemplary operation of wireless communication system 100 that comprises wireless UE 110 and wireless communication networks 101-102 to deliver the priority communication service. The operation may differ in other examples. In UE 110, circuitry 112 correlates the network IDs for wireless communication networks 101-102 with respective instructions “A” and “B” for the priority communication service (201). Circuitry 112 identifies a user request for the priority communication service (202), and in response, identifies the network ID for the currently serving one of networks 101-102 (203).

When wireless communication network 101 is currently serving UE 110 (203), circuitry 112 identifies instruction “A” based on the correlation of network ID “101” with instruction “A” (204). Instruction “A” directs UE 110 to use the priority communication service in a normal mode. Circuitry 112 exchanges network signaling for the priority communication service with radios 111 based on instruction “A” (205). Circuitry 112 exchanges user data for the priority communication service with radios 111 based the network signaling. Radios 111 and wireless communication network 101 exchange the network signaling and user data for the priority communication service (206).
