A system for scheduling group resources during trunking communication, comprising a trunking switch center and base stations connected to the trunking switch center,

• the trunking switch center is configured to classify the base stations into at least one co frequency base station set and mark a base station that cannot be classified into the at least one co frequency base station set as a different frequency base station according to central frequencies and home regions of the base stations;
• when a group call is established, to allocate the same trunking shared channel and designate the same packet delivery time to base stations in one co frequency base station set, and notify each base station in the co frequency base station set of the allocated trunking shared channel and the designated packet delivery time;
• and
• the base stations in the co frequency base station set are configured to start to send trunking packets on the allocated trunking shared channel at the designated packet delivery time.
