Method for sending a communication unit parameter to a plurality of communication units
First Claim
1. In a wireless communication system that includes a plurality of communication units, a method for sending a communication unit parameter to the plurality of communication units, the method comprising steps of:
- sending the communication unit parameter to the plurality of communication units during a first period of time, wherein the communication unit parameter is sent using one of either a group update method and an individual update method;
determining a first set of communication units of the plurality of communication units that did not receive the communication unit parameter; and
sending the communication unit parameter to the first set of communication units during a second period of time, wherein the communication unit parameter is sent using the individual update method.

Abstract
In a wireless communication system (100), a communication unit parameter is sent to a plurality of communication units (105-108) during a first period of time using either a group update method or an individual update method (401). A first set of communication units that did not receive the communication unit parameter is determined (402) and, during a second period of time, the communication unit parameter is sent to the first set of communication units using only the individual update method (403). During the second period of time, the communication unit parameter is sent based on primary and/or secondary regions of operation for each communication unit and also upon detection of update opportunities. This process can be repeated for any number of communication unit parameters (404). Using this method, updates of communication unit parameters have a high likelihood of being successfully and efficiently performed.

11. In a key management controller that includes a processor, wherein the key management controller operates within a wireless communication system and controls encryption keys for a plurality of communication units within the wireless communication system, a method for sending encryption information to the plurality of communication units, the method comprising steps of:
-
sending, via the wireless communication system, at least one encryption key to the plurality of communication units during a first period of time, wherein the at least one encryption key is sent using one of either a group update method and an individual update method; determining a first set of communication units of the plurality of communication units that did not receive the at least one encryption key; sending, via the wireless communication system, the at least one encryption key to the first set of communication units during a second period of time, wherein the at least one encryption key is sent using the individual update method; sending, via the wireless communication system, an encryption map index corresponding to the at least one encryption key to the plurality of communication units during a third period of time, wherein the encryption map index is sent using one of either the group update method and the individual update method; determining a second set of communication units of the plurality of communication units that did not receive the encryption map index; and sending, via the wireless communication system, the encryption map index to the second set of communication units during a fourth period of time, wherein the encryption map index is sent using the individual update method. - View Dependent Claims (12, 13, 14, 15, 16, 17)
