Title: DATA TRANSMISSION METHOD, DEVICE AND SYSTEM
Abstract:
The present invention discloses a data transmission method, device and system, for diverting local service data between a UE and an EPC to a local service server provided at access network side when local service data exists between the UE and EPC, thus making it unnecessary to configure a special APN at an HSS, and unnecessary for a core network to process the local service data, thereby avoiding service jitter, improving a service effect, and optimizing the entire system architecture and functions. The present invention provides a data transmission method comprising: monitoring S1 interface data between an Evolved Node B (eNB) and an Evolved Packet Core (EPC) network; when local service data exists between a UE and an EPC, diverting the local service data between the UE and EPC to a local service server provided at an access network side.
