<P>PROBLEM TO BE SOLVED: To provide apparatus and methods for the communication of system state information change to wireless devices in a content server network in a resource and power efficient manner. <P>SOLUTION: A method for conveying system state information to a wireless device includes sending a primary message including first information configured to communicate a first current system state to the wireless device, and then sending second information set usable by the wireless device to update system state information. By summarizing or abbreviating the first information, a receiving device can easily compare to the past system states to determine whether further processing, such as processing of the second information, is needed, thereby affording the conservation of processing and power resources of a receiving device. Corresponding apparatus is also disclosed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
