Abstract (en)
[origin: WO2013053414A2] The invention relates to a radio-communication system (100) for Push-to-Talk applications, comprising: a narrow-band PMR-technology terminal (110) capable of connecting, via a radio-electric interface, to a narrow-band network infrastructure (120) for accessing, via a PTT server (150), a set of narrow-band PTT resources or applications (160); and a wide-band-technology terminal (210, 510, 610) capable of connecting, via a radio-electric interface, to an IP-WAN network (240) for accessing, via a server (265), a set of wide-band PTT resources or applications (260), wherein said terminal (210, 510, 610) comprises a client PTT application (215, 515, 615) on the IP-WAN network configured to establish an IP connection between the terminal (210, 510, 610) and a PTT server (250, 550, 550a, 550b, 550c, 650, 650a, 650b, 650c) over the IP-WAN via an interface (225, 525, 625a, 625b), such that said terminal (210, 510, 610) can access the narrow-band PTT resources or applications (160) and establish a communication channel with the terminal (110).
