Continuous interface maintenance for group communications to a wireless communications device group
First Claim
1. A method for selectively maintaining an open multicast interface to a communication computer device that is controlling wireless communication to at least one of a plurality of wireless communication devices that are in a communication group, the method comprising:
- registering at least one wireless communication device that is a member of the communication group at the communication computer device, the at least one wireless communication device configured to receive group-directed communications for the communication group, wherein the at least one wireless communication device is configured to selectively unregister itself from the communication computer device;
maintaining with the communication computer device a list of currently registered wireless communication devices that are members of the communication group, wherein maintaining the list comprises removing any wireless communication device that selectively unregisters itself;
establishing at least one multicast interface, wherein said at least one multicast interface comprises a broadcast A10 interface, between the communication computer device and another computer device on a wireless communication network, the at least one multicast interface permitting delivery of the group-directed communications to the at least one wireless communication device;
determining, via the maintained list, whether any wireless communication devices remain registered as members of the communication group; and
in response to the determining, maintaining the at least one multicast interface so long as any wireless communication device remains registered with the communication computer device as a member of the communication group after the group-directed communications have ended,wherein the communication group comprises a group of wireless communication devices registered to conduct group communications among each other.

Abstract
A system, method, and computer device that selectively maintain an open interface to a communication control device that is controlling wireless communication to at least one of a plurality of wireless communication devices that are in 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 interface is established between the communication control device and another computer device on the wireless communication network, such as a broadcast A10 interface with a broadcast serving node (BSN). The communication control device will then maintain the interface while the at least one wireless communication device, or at least one member device of the communication group, is registered such that group communications can more rapidly be delivered to the wireless communication device.

8. A system for selectively maintaining an open multicast interface to at least one of a plurality of wireless communication devices that are in a communication group, the at least one wireless communication device configured to receive group-directed communications for the communication group, the system comprising:
-
a memory storing instructions; and a processor configured to execute the instructions, the instructions causing the processor to perform operations comprising; registering the at least one wireless communication device; establishing at least one multicast interface wherein said at least one multicast interface comprises a broadcast A10 interface, between a communication computer device and another computer device on a wireless communication network to permit delivery of the group-directed communications to registered wireless communication devices; and maintaining a list of currently registered wireless communication devices that are members of the communication group, wherein maintaining the list comprises removing any wireless communication device that selectively unregisters itself, wherein the communication group comprises a group of wireless communication devices registered to conduct group communications among each other; determining, using the list, whether any wireless communication devices remain registered as members of the communication group; and maintaining, in response to the determining, the at least one multicast interface while any wireless communication device remains registered with the communication computer device as a member of the communication group after the group-directed communications have ended. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A communication computer device resident on a wireless communication network and configured to selectively control wireless communications for wireless communication devices that are registered therewith, with at least one wireless communication device being a member of a communication group of wireless communication devices and configured to receive a group-directed communication for the communication group, the communication computer device comprising:
-
means for registering the at least one wireless communication device that is a member of the communication group of wireless communication devices; means for maintaining a list of registered wireless communication devices; means for removing from the list any wireless communication device that selectively unregisters itself; means for establishing one or more multicast interfaces wherein said one or more multicast interfaces comprise a broadcast A10 interface, between the communication computer device and another computer device on the wireless communication network for group communications directed to the registered wireless communication devices; means for determining, using the list, whether there is any remaining registered member of the communication group; and means for maintaining, in response to the determining, at least one multicast interface while any wireless communication device remains registered with the communication computer device as a member of the communication group after the group-directed communication has ended, wherein the communication group comprises a group of wireless communication devices registered to conduct group communications among each other. - View Dependent Claims (16, 17, 18, 19, 20, 22)
