An audio data sharing method for radio broadcast systems includes sharing audio data using vehicle-to-vehicle communication and vehicle-to-infrastructure communication between vehicles and infrastructure units in low reception areas for radio broadcasting. The audio data sharing occurs by means of tuner leasing. The method also includes forming a framework for message sharing between the different units. The method enables uninterrupted audio data availability in low reception areas for enhancing the customer experience.

A wireless communication network controls data services that are delivered over a wireless access point. The wireless access point broadcasts service identifiers for the data services to user communication devices. The user communication devices and the wireless access point exchange the user data for the data services. The wireless access point and a network gateway exchange the user data for the data services. The network gateway processes the user data to determine if one of the data services falls below a Quality-of-Service (QoS) threshold. If one of the data services falls below its QoS threshold, then the network gateway transfers an instruction to stop wirelessly broadcasting the service identifier for the data service. The wireless access point receives the instruction and stops its wireless broadcast of the service identifier for the data service.
