<p>2090655PC 24 (57) ABSTRACT When a communication session is implemented, the communications of a direct mode terminal (13) may be mediated via a direct mode gateway (15) such that mes- sages of adirect mode first terminal are addressed with identification information ofthe direct mode gateway. In the invention identity information ofa user of the direct mode terminal is delivered to a trunked mode terminal (11, 2) in a user plane signalling message of the communica- tion session. In terminal procedures identity of the direct mode gateway may be replaced by identity information received in the user plane signalling message. Identity of the direct mode terminal is then in a simple manner made available to terminal procedures of the trunked mode ter- minal. (Figure 1)</p> |
