An apparatus and method for dynamic group prioritization in a communication network includes a first step (400) of defining a dynamic list of group participants by an application, such as a dispatch function. A next step (402) includes sending a request to a Group Management Function, wherein the request includes a requested group priority and the list of group participants. A next step (404) includes allocating a unique identifier to the group and assigning a group priority to the group. A next step (406) includes notifying the application, group participants, and network of the unique identifier and the network of the assigned group priority. The assigned priority of the group and its flows can be dynamically altered in real-time while the group is active.
