A method (500, 600) for conducting group communications, comprising: receiving at a group communication participating UE (120, 800) information defining a group communication from a first network; and detecting at the UE an availability of at least one local uni-directional radio broadcast network outside the first network, wherein the at least one local uni-directional radio broadcast network is an FM/AM transmission, characterised in that: detecting the availability of the at least one local uni-directional radio broadcast network further comprises determining whether the UE has an FM/AM receiver; if the UE has an FM/AM receiver and can receive the FM/AM transmission: transmitting from the UE an acknowledgement indicating an intention to connect to the at least one local uni-directional radio broadcast network; and monitoring at the UE the group communication on the at least one local uni-directional radio broadcast network using the UE's FM/AM radio receiver; and receiving at the UE group communication media over a FM/AM channel; if the UE has no FM/AM receiver and/or cannot receive the FM/AM transmission: transmitting from the UE an acknowledgment indicating that the UE will be a unicast member of the group communication; and receiving at the UE group communication media over a unicast channel. receiving at a group communication participating UE (120, 800) information defining a group communication from a first network; and detecting at the UE an availability of at least one local uni-directional radio broadcast network outside the first network, wherein the at least one local uni-directional radio broadcast network is an FM/AM transmission, characterised in that: detecting the availability of the at least one local uni-directional radio broadcast network further comprises determining whether the UE has an FM/AM receiver; if the UE has an FM/AM receiver and can receive the FM/AM transmission: transmitting from the UE an acknowledgement indicating an intention to connect to the at least one local uni-directional radio broadcast network; and monitoring at the UE the group communication on the at least one local uni-directional radio broadcast network using the UE's FM/AM radio receiver; and receiving at the UE group communication media over a FM/AM channel; if the UE has no FM/AM receiver and/or cannot receive the FM/AM transmission: transmitting from the UE an acknowledgment indicating that the UE will be a unicast member of the group communication; and receiving at the UE group communication media over a unicast channel. detecting the availability of the at least one local uni-directional radio broadcast network further comprises determining whether the UE has an FM/AM receiver; if the UE has an FM/AM receiver and can receive the FM/AM transmission: transmitting from the UE an acknowledgement indicating an intention to connect to the at least one local uni-directional radio broadcast network; and monitoring at the UE the group communication on the at least one local uni-directional radio broadcast network using the UE's FM/AM radio receiver; and receiving at the UE group communication media over a FM/AM channel; transmitting from the UE an acknowledgement indicating an intention to connect to the at least one local uni-directional radio broadcast network; and monitoring at the UE the group communication on the at least one local uni-directional radio broadcast network using the UE's FM/AM radio receiver; and receiving at the UE group communication media over a FM/AM channel; if the UE has no FM/AM receiver and/or cannot receive the FM/AM transmission: transmitting from the UE an acknowledgment indicating that the UE will be a unicast member of the group communication; and receiving at the UE group communication media over a unicast channel. transmitting from the UE an acknowledgment indicating that the UE will be a unicast member of the group communication; and receiving at the UE group communication media over a unicast channel.
