Abstract: Disclosed are a method, system and device for switching a communication path. The method comprises: an MME receives a request message, wherein the request message is used for requesting for a communication in a D2D path; and the MME sends at least one bearer resource processing request message to a GW, wherein the bearer resource processing request message is used for notifying that a data path on a network side is switched from a CN path to the D2D path to be transmitted. The step that the MME receives the request message may comprise: the MME receives the request message from a eNodeB; or, the MME receives at least one bearer processing request from at least one of the two pieces of UE which have performed a D2D communication through the eNodeB.
Abstract translation: 公开了一种用于切换通信路径的方法，系统和设备。 该方法包括：MME接收请求消息，其中请求消息用于请求D2D路径中的通信; 并且MME向GW发送至少一个承载资源处理请求消息，其中承载资源处理请求消息用于通知网络侧的数据路径从CN路径切换到要发送的D2D路径。 MME接收请求消息的步骤可以包括：MME从eNodeB接收请求消息; 或者，MME从已经通过eNodeB执行了D2D通信的两个UE中的至少一个接收至少一个承载处理请求。

Abstract: A system, method and apparatus for processing a packet data service are provided. The system may include: an SGSN, configured to acquire at least one of an APN and an RNC identifier in a UMTS, and select, when an RAN CDN has been enabled in the UMTS, the RAN CDN according to at least one of the APN and the RNC identifier to process a packet data service in a UMTS network. Or, the system may include: an MME, configured to acquire at least one of an APN and an eNodeB identifier in an LTE, and select, when an RAN CDN has been enabled in the LTE, the RAN CDN according to at least one of the APN and the eNodeB identifier to process a packet data service in an LTE network.
