The invention provides a load resource management and device, an OMC and a virtualized EPC architecture. The load resource management method applied to a load resource management device side comprises the following steps: receiving a load status of virtual network element equipment in an OMC own management range sent by each OMC; determining a load factor among all virtual network element equipment according to the load status of the virtual network element equipment, wherein the load factor is used for identifying the loading condition of the virtual network element equipment; returning the load factor among the virtual network element equipment to each OMC so that the OMC can forward the load factor to the corresponding virtual network element equipment in the own management range thereof, sending the load factor to a base station by the virtual network element equipment, and determining the to-be-attached virtual network element equipment for the user equipment according to the load factor by the base station. Through the adoption of the method provided by the invention, the resource difference restriction between different manufacturers is broken, the network management is simplified, and the network operation and maintenance are unified; and the load resource management method is small in influence to the network transformation, and easy to implement.
