Quality of Service Control and Usage Monitoring Mechanisms for Unlicensed Access
Abstract:
This disclosure relates to techniques for managing and monitoring access to a cellular network using unlicensed spectrum. According to some embodiments, policy information indicating permissible and/or non-permissible uses of unlicensed spectrum to access a radio access network of the cellular network may be distributed to elements of the radio access network, such as base stations. A base station establishing a radio bearer with a wireless device may receive information regarding a service type associated with the radio bearer and may determine radio bearer characteristics, potentially including whether to establish the radio bearer using unlicensed or licensed spectrum, based at least in part on the service type associated with the radio bearer and the network policy information. The base station and/or the user device may also report information regarding unlicensed (and possibly also licensed) network access by the user device to a core network of the cellular network.
