description The invention provides a method and device for separating services from routing. The method and device are applied to a gateway GPRS support node (GGSN). The method includes the following steps that: an activation message of the context of a packet data protocol (PDP) for a first terminal is received, wherein the activation message carries the first access point name (APN) of the first terminal; a first service gateway corresponding to the first APN is determined according to corresponding relationships between APNs and service gateways, and a connection relationship of the first terminal and the first service gateway is constructed; and service data streams from the first terminal are received, and the service data streams are forwarded to the first service gateway according to the connection relationship. According to the method and device of the invention, a part of services in the GGSN are guided to the service gateway, and therefore, the network management overhead of the GGSN can be reduced, and network
