Communication method and device

The invention discloses a communication method and device. The method comprises the following steps: determining function parameter configuration information of a distributed service center in the distributed service center, wherein the function parameter configuration information comprises distributed service center device identification, network identification, cluster identification, cluster information, service identification, core network service center identification or address information; and determining communication demand of the distributed service center according to the function parameter configuration information, and sending a communication request message to corresponding equipment. A core network service center device gives a response according to the communication request message after receiving the communication request message sent by the distributed service center; and an end node receives a system broadcast message sent through an air interface, and then, updates cluster state information according to the system broadcast message. Through the communication method and device, burden caused by an access device to core network storage and signaling processing can be reduced, and control function can be localized, thereby reducing time delay due to control surface signaling process.
