INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Systems and methodologies are described that facilitate providing software upgrade notifications to user devices that utilize unicast and multicast communication techniques in a wireless communication environment. Bandwidth and power consumption is minimized by permitting determination to be made regarding whether a given software update is relevant to the user device prior to attempting a download or receiving a notification thereof. Additionally, evaluation of version number and software identity facilitates determining whether to employ a unicast software check-up protocol or a multicast software check-up protocol. Software upgrade information may also be transmitted over a multicast channel for a predetermined time period, after which a user device may initiate a unicast check-up protocol to receive software upgrade information. ## Claims ### Claim 1 A method implemented on a server for providing software upgrades, the method comprising: transmitting a software upgrade notification on a data channel, the software upgrade notification including one or more server tokens associated with m most recent software upgrades available on the server, where m is an integer;
