METHOD FOR ENABLING RADIOELECTRIC COEXISTENCE BETWEEN TWO PMR DEVICES OF WHICH ONE IS A NARROWBAND TYPE AND THE OTHER IS A BROADBAND TYPE

摘要

The present invention relates to a method for enabling radioelectric coexistence between two devices based on personal mobile radio or PMR technology, of which one is a narrow band device and the other is a broadband device, and each device interacts via a radioelectric link with respective base stations connected to a control unit for the radio resource of their respective networks, characterized in that it comprises the following steps:
detection of the presence of a narrow band radioelectric emitter device in the vicinity of device,transmission of a message on the broadband network, addressed to the control unit, which message signals the presence of a possible narrow band emitter close to said device, andassignment by the control unit of new frequency blocks for uplinks, only in predefined allocated periods.

A method for enabling radioelectric coexistence between two devices based on personal mobile radio or PMR technology, of which one is a narrow band device and the other is a broadband device, and each device interacts via a radioelectric link with respective base stations connected to a control unit for the radio resource of their respective networks, characterized in that it the method comprising the following steps:
detection of the presence of a narrow band radioelectric emitter device in the vicinity of device, transmission of a message on the broadband network, addressed to the control unit, which message signals the presence of a possible narrow band emitter close to said device, and assignment by the control unit of new frequency blocks for uplinks, only in predefined allocated periods.
