Abstract
The invention discloses a method for overload indication in cross-access network, which is suitable for a wireless communication system comprising a plurality of access networks. The various access networks are connected with each other through IUR interfaces and various access networks comprise node B and radio network controllers. The method comprises the following steps: Step 1, an overload indication signaling for IUR interface is sent to the access network connected with the access network through the IUR interface by utilizing the IUR interface when the access network is in the overload condition; Step 2, the access network connected with the access network through the IUR interface receives the overload indication signaling for IUR interface and obtains and correspondingly processes the overload information of the access network. Under the circumstance that the access network is overloaded, the invention realizes that other access networks connected with the overloaded access network through the interface can quickly obtain the overload indication and the specific overload information so as to prevent other access networks from applying the ineffective or negative operations to the access network and simultaneously also reduce the overload factors of the overloaded access network and ensure that the overloaded access network achieves the normal state as soon as possible.
