Embodiments of the present invention disclose a method for assigning a dedicated channel uplink to a service subscriber of a trunking group. When a trunking group call is established, a network allocates a group call channel uplink to the trunking group, assigns the group call channel uplink to the service subscriber upon receiving an uplink access request sent by the service subscriber, establishes a dedicated channel uplink to be allocated to the service subscriber; and assigns the dedicated channel uplink to service subscriber. Through the method, a dedicated channel uplink is assigned to a service subscriber without increasing the time lag before the speech of the service subscriber. Furthermore, a dedicated channel uplink may be assigned to a service subscriber with a higher priority level without increasing the time lag before the speech of the service subscriber with the higher priority level.
