Patent ID: 8335532

Claim:
A wireless communication device, comprising: circuitry configured to receive a request to send a data package to a target over a group communication channel; circuitry configured to determine whether at least one group communication channel is not established with a group communication server; circuitry configured to selectively store the data package in a queue in response to determining that at least one group communication channel is not established with the group communication server, wherein the queue includes a plurality of data packages; circuitry configured to determine whether the memory size of the plurality of queued data packages is greater than a predetermined memory size threshold; circuitry configured to establish the group communication channel with at least the group communication server in response to determining that the memory size of the plurality of queued data packages is greater than the predetermined memory size threshold; and circuitry configured to send all queued data packages intended for the target to at least the group communication server via the established group communication channel.
