CONTINUOUS INTERFACE MAINTENANCE FOR GROUP COMMUNICATIONS TO A WIRELESS COMMUNICATION 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;
establishing at least one multicast 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 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.

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.

20. A non-transitory computer-readable medium 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 non-transitory computer-readable medium comprising:
-
at least one instruction to register 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; at least one instruction to establish at least one multicast 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; at least one instruction to determine whether any wireless communication devices remain registered as members of the communication group; and at least one instruction to maintain, in response to the determining, 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.
