Abstract

A system and method for providing quality-of-service based network resource allocation and utilization in a dynamic network environment. For example, a wireless communication network may comprise a first system and a second system. The first system may provide a current service to a user at a current quality level. The first system and second system may establish a wireless communication link. At least one of the first and second systems may determine whether utilizing one or more resources of the second system will provide the current service to the user at a higher level of quality than the current quality level. One or more resources of the second system may be allocated for providing the current service to a user at a higher quality level. The allocated resources may be utilized to provide the current service to the user at a higher quality level than the current quality level.
