A method, system and software to dynamically allocate bandwidth on an application flow basis in a non-Internet-Protocol Multimedia Subsystem (non-IMS) environment is described. The method includes: receiving a request to create an application flow for an Internet Protocol (IP) filter with desired Quality of Service (QoS) properties; searching for an access bearer that is comparable to the desired QoS properties; when a comparable access bearer is not found, creating the access bearer adapted to support the IP filter and the desired QoS properties; and associating the application flow with the access bearer. According to various embodiments, a method to add a new application flow from a flow bandwidth manager to a Policy Control and Charging Rules Function (PCRF) is also described The method can include: searching for an access bearer that supports an IP filter and desired QoS properties; when there is an existing access bearer, mapping the new application flow to the access bearer and modifying the properties of the existing access bearer to support the new application flow. and creating a new access bearer when there is no existing access bearer.
