To meet the booming development of diversified services and new applications in the future, the fifth-generation mobile communi-cation system (5G) has arisen. Resources are increasingly scarce in the dynamic time-varying of 5G networks. Allocating resources effectively and ensuring quality of service (QoS) requirements of multi-services come to be a research focus. In this paper, we uti-lize effective capacity to build a utility function with multi-QoS metrics, including rate, delay bound and packet loss ratio. Taking advantage of opportunity cost (OC), we also propose a multi-QoS guaranteed resource allocation algorithm for multi-services to con-sider the future condition of system. In the algorithm, according to different business characteristics and the theory of OC, we pro-pose different selection conditions for QoS users and best effort (BE) users to choose more reasonable resources. Finally, simula-tion results show that our proposed algorithm achieves superior system utility and relatively better faess in multi-service scenarios.
