Method for mitigating interference is established by means of a local wireless communication (204, 206) between a first portable communication device (PCD) (102, 301) and a second PCD (104, 302). The first and second PCD (301, 302) respectively communicate with first wireless network (110, 306, 310) and second wireless network (112, 308, 312) having different wireless air interface protocols. The local wireless communication link (107) is used to share (208) information (109, 111) concerning one or both of the first and second PCD. The information is then used to determine a communication priority (210) as between the first and second PCD with respect to at least one communication mode. The information is also used to selectively establish (212) an interference mitigation policy (304) to provide assured communications for the PCD with priority. The interference mitigation policy is executed (214) in the first and second PCD to cooperatively provide assured communication for the PCD with priority.
