Abstract
A method of automatic creation of a talk group in a wireless radio communication system comprising a plurality of mobile stations, said method comprising the steps of: transmitting by a first mobile station an emergency message containing at least its ID and localization data; transmitting by other mobile stations their IDs and localization data in response to said emergency message; creating said talk group by selecting those mobile stations which transmitted their IDs and localization data.
Claims25
A method of automatic creation of a talk group in a wireless radio communication system comprising a plurality of mobile stations, said method comprising:
- wirelessly broadcasting, by a first mobile station to other mobile stations in the plurality of mobile stations, a message containing at least a first mobile station ID and localization data associated with the first mobile station;
- wirelessly receiving, by the first mobile station, response messages from the other mobile stations transmitted in response to receiving said broadcast message;
- and
- creating said talk group by selecting ones of the other mobile stations as a function of the response messages that were wirelessly received at the first mobile station.
A mobile station comprising means for signal transmission, means for signal reception, a microphone, an audio processing circuitry, a keypad, a microprocessor, a memory, a localization circuitry, and a switch means being adapted to (i) initiate wireless broadcast of a message to other mobile stations out of a plurality of mobile stations in a wireless communication system, said message comprising localization data associated with the mobile station and an ID of said mobile station, (ii) initiate wireless receipt of response messages from the other mobile stations transmitted in response to receiving the broadcast message, and (ii) initiate creation of a talk group comprising all or a subset of the other mobile stations as a function of receipt of the response messages that were wirelessly received.
An infrastructure device in a wireless communications system configured to:
- receive, from a first mobile station, a broadcast message, wherein said broadcast message comprises a first mobile station ID and localization data associated with the first mobile station;
- receive, from other mobile stations, respective response messages including other mobile stations IDs and localization data transmitted by each of the other mobile stations in response to receiving the broadcast message;
- and
- dynamically create a talk group by selecting all or a subset of the responding other mobile stations as a function of the response messages and were wirelessly received at the first mobile station.
