Method, device and system for service resource scheduling

The invention provides a method, a device and a system for service resource scheduling and belongs to the technical field of core networks. The method includes that a strategy receives service information of service dataflow reported by deep packet inspection equipment, generates corresponding quality of service (QoS) control strategy according to the service information, and transmits the QoS control strategy to a GREAN (GSM EDGE radio access network) through SGSN (service GPRS (general packet radio service) supporting node) to enable the GREAN to perform radio resource scheduling to the service dataflow according to the QoS control strategy. According to the technical scheme, differentiated radio resource scheduling can be performed to data services by means of high-precision service identification without influences on network awareness of users.
