Disclosed are a method and device for communication, comprising: receiving on a distributed service center a communication request message of an end point node, where the communication request message carries an identifier of the end point node; transmitting a communication processing message of the end point node to a core network, where the communication processing message carries the identifier of the end point node; and, when a communication processing message transmitted by the distributed service center to the core network is received, returning a communication response message to the end point node. Employment of the present application not only greatly reduces the load that an access device incurs on the core network in storage and signal processing, but also localizes a control function, thus greatly reducing delay caused by a control plane signaling process.
