METHOD AND DEVICE OPTIMISING CALL/BROADCAST ALERT MESSAGE RECEPTION BY SELF-SUPPLIED WIRELESS COMMUNICATION DEVICES

摘要

FIELD: radio engineering.;SUBSTANCE: invention refers to wireless communication networks and is intended for transmission of call/broadcast alert message to wireless communication devices and for reception of call/broadcast alert message. Wireless communication network accept each incoming call arranged for wireless communication device by transmission of call/broadcast alert message in corresponding section of digital radio communication frame of preset format. As response to each broadcast event the network transmits repeating broadcast alert message notifying about availability of broadcast information from network. Broadcast alert message is retransmitted in each frame of digital radio communication. Other sequence features wireless communication device operation in this network. As response to activation from expectation state the wireless communication device estimates quality of received signal. Wireless communication device also receives scheduled network transmission of call alert message and set of copies (at least one) of repeating alert message transmitted through broadcast network repeated for each scheduled transmission of call alert message. This number varies in inverse proportion to certain quality of signal.;EFFECT: functional enhancement due to available broadcasting information from network.;53 cl, 7 dwg
