| 摘要 |
The present invention relates to a radio communications gateway device (200) for retransmitting messages of different forms between a first radio communications network (202) and a second radio communications network (204), said gateway device (200, 300) including: a first transmitter (214) capable of processing the radio communications of the first network (202) according to a first coding scheme, a second transmitter (216) capable of processing the radio communications of the second network (214) according to a second coding scheme, and a switch (201) which, when the gateway device is activated, connects the first and second transmitters (214, 216) to retransmit voice messages from a group communication processed by one of said transmitters (214, 216) to the other of said transmitters (214, 216), characterized in that said switch includes a controller (215) for automatically implementing: the gateway device in active mode upon reception of a voice message of a group communication; the gateway device in suspended mode by suspending the switch (201) so that said first and second transmitters (214, 216) process independently of one another voice or non-voice messages between the gateway device and one of the two radio communication networks, respectively, the suspended mode being activated when signaling data of the messages of different forms indicate a change in communication other than a group voice communication. |
