The disclosure provides a method, an apparatus and a system for processing a non-resource-reservation type service, wherein the method for processing the non-resource-reservation type service comprises: acquiring a service type of a received non-resource-reservation type service; according to the service type, querying a Network Attachment Control Function (NACF) entity about parameter information of the non-resource-reservation type service; generating a control strategy according to a present usage state of an interactive resource and the parameter information; according to the generated control strategy, controlling the received non-resource-reservation type service. The disclosure solves the problem that the non-resource-reservation type service cannot be admission-controlled in the Next Generation Network (NGN) of the prior art, and can efficiently use resources.

A resistance welding high frequency transformer and a high frequency resistance welding machine using the same are disclosed. The transformer comprises a magnetic core (), primary coils () and secondary coils (). The primary coils and the secondary coils are alternatively positioned layer by layer. Each secondary coil is arranged between two primary coils. The primary coils are provided at the internal side and the external side of the secondary coil. The secondary coil is composed of red copper pipes through which water flows. Each secondary coil is wound with one to two turns. The red copper pipes of the secondary coils and rectifier diodes constitute a full-wave rectifier circuit. The resistance welding high frequency transformer can be wound conveniently. Its structure can reduce size, weight, leakage inductance and copper circuit loss, and the heat from the primary coils and secondary coils is dissipated conveniently, thus enabling the high-frequency transformer to output high current and high power with a high duty cycle. The resistance welding machine using the transformer has high power factor, high output power, small volume, light weight, and saves energy and material, which is especially suitable to produce a suspension spot welding machine with the integration of the transformer and welding tongs.
