ABSTRACT:
In a mobile radio system wherein a common group call is concurrently transmitted by several primary stations, each primary station includes in the structure of the call the identities of other primary stations which are transmitting the same call. In a TDMA system these identities may be transmitted in a time slot of a dedicated frame F, such as a control slot C, a ramp slot R, or an associated control slot AC. When the quality of the call as received by a mobile secondary station deteriorates, handover to the best available primary station transmitting the same group call can therefore be effected directly by the secondary station without the need for a signaling exchange with the primary stations involved. The invention is also applicable to FDMA systems.
