Continuous broadcast interface maintenance for group communications to wireless communication devices

A system, method, and computer device that selectively maintain an open broadcast interface to a communication control device that is controlling wireless communication to at least one wireless communication device that is configured to receive group-directed communications for a communication group, such as a push-to-talk (PTT) group. In one embodiment, the wireless communication device registers at the communication control device, such as a base station controller, and at least one broadcast interface is established between the communication control device and another computer device, such as a broadcast A10 interface with a broadcast serving node (BSN). The communication control device maintains the broadcast interface while the wireless communication device configured to receive group-directed communications is registered such that group-directed broadcast communications can more rapidly be delivered to the wireless communication device. When the communication control device determines that the group communication has ended, it releases the broadcast interface.
