- the structure 220 determines whether the SDS application requires going through an IP network or not. The SDS application does not need to go through the IP network, so the lower structure 210 becomes transparent, and the SDS application uses a TCS type interface (for Tetra Connectlvlty Server, in English) to reach the network infrastructure appropriate legacy.

Otherwise, the structure 220 will select the legacy network. If on the other hand the IP data is advanced IP such as http (for Hyper Text Transfer Protocol, for example), then the structure 210 supports this IP data. Thus, according to FIG. 4b, this datum being of IP type, then the lower structure 210 selects the appropriate IP access network 106, 107, 108, as a function of the priority level. assigned to the data, the capacity or the load of the access networks 106, 107, 108, of unicast or broadcast configuration, or of the load balancing between said networks.

- the structure 220 determines whether the voice service requires going through an iP network or not. Since the voice service does not need to go through the IP network, then the lower structure 210 becomes transparent, and the voice service uses a TCS (for Tetra Connectivity Server) type interface in order to reach the appropriate legacy network infrastructure. .
- TCS Tetra Connectivity Server
- the capacity or the load of the access networks 103, 106, 107, 108, the unicast or broadcast configuration, or even the load balancing between said networks introduces the IP network as support for the legacy network.
- the voice service becomes IP, then the lower structure 210 selects the appropriate IP access network 106, 107, 108.
