A method and system for dynamically allocating backhaul bearer service based on network loading conditions to help use backhaul-network resources more efficiently. A RAN detects an event relating to bearer service establishment for a given application. Then the RAN identifies a standard bearer service for the given application, where the standard bearer service has a first quality of service. After detecting the event, the RAN determines that a load of the backhaul communication network does not exceed a load threshold. Then, based on the determination that the load of the backhaul communication network does not exceed the load threshold, the RAN selects a bearer service for the given application, where the selected bearer service has a second quality of service that is higher than the first quality of service. Next, the RAN causes the selected bearer service to be established.
