Abstract:
1. A mobile communications device for reducing packet collision in a random access wireless communication network the mobile communication device capable of supporting communications in both a cellular network and the random access wireless communication network during a call session, comprising: a processor configured to establish a connection with a server in the random access wireless communication network, and configured to update a registration with the cellular network to route the call session through the random access wireless communication network based on information from the server; a data generator under the control of the processor and configured to generate a data unit during the call session, the data unit generated at a rate having a fixed period, wherein the time required to transmit the data unit is shorter than the total fixed period; and a transceiver under control of the processor, wherein the transceiver receives a message that identifies the mobile communications device's assigned slot index, wherein the message also informs the device of the maximum number of slots, and configured to transmit the data unit to the server during a particular time slot, wherein the particular time slot is based upon the slot index assigned to the mobile communications device by the server, wherein the slot index identifies at least one of a plurality of transmission periods during which the data unit is to be transmitted.
