Abstract
A mobile device sends to a message a wireless network. The message indicates a plurality of different protocol types of broadcast messages to be processed as broadcast-to-unicast messages during a low power mode of operation of the mobile device. The protocol type of a given broadcast message is identifiable in a protocol identifier field of the broadcast message. The mobile device maintains its wireless receiver in a powered down state during the low power mode of operation while broadcast messages are broadcasted from the wireless network. For each broadcast message of each said indicated protocol type provided in the message sent to the wireless network, the mobile device monitors to receive via the wireless receiver a unicast message from the wireless network. The mobile device identifies broadcast message information of the broadcast message within the unicast message.
