In a packet switched system used for speech communication, a user entering a silent period, start to transmit silence descriptor information (SID). According to the invention, a speech user is not allocated the same resources for transmission of SID as for the speech communication. Instead, the user is, upon entering a silent period, reallocated to a SID communication channel, shared between a number of different users in silent mode. The resources used for speech may then be more advantageously utilized for other speech users, and is not occupied for SID transmissions only. In an alternate embodiment of the invention, when a mobile station is in silent mode, it receives and transmits associated signaling information on the same transmission resources as those used for the SID transmissions. |
