Abstract: Embodiments of the present application provide a method for dynamically creating a local packet data network, an apparatus, and a system. The method includes: receiving a user plane network element selection request, allocating a first user plane network element to UE based on cell location information, a service type, and an access point name of the UE, and then sending a user plane network element response message that carries an identifier of the first user plane network element to a session management network element, so that the session management network element sends a new session establishment request to the first user plane network element.

Abstract: A method for configuring a path for intercepting user data, a method for intercepting user data, an apparatus, a system, a control plane entity and a user plane entity, the method for configuring the path for intercepting user data comprises: acquiring a target to be intercepted and an intercepting interface address; configuring data path configuration information on a user plane entity GW-U according to the target to be intercepted and the intercepting interface address; sending the data path configuration information to the user plane entity GW-U so that the GW-U establishes a path for data transmission; initiating an establishment of an intercepting connection of an intercepting interface to an intercepting entity based on the intercepting interface address so as to transmit the data of the target to be intercepted.

Abstract: The present disclosure a service path changing method and apparatus, including: determining, by an MME, that a UE needs to be handed over from a first AG to a second AG; and instructing, by the MME, the UE to notify, according to bearer information used to perform service transmission between the second AG and the UE and assigned by the second AG, a service peer end that an IP address of the UE is changed from a first IP address assigned by the first AG to a second IP address assigned by the second AG. It is not required to add the first IP address assigned to the UE by the first AG into the IP address segment maintained by the second AG, and it is unnecessary to change routing information of a router in a PDN to route downlink data of the UE to the second AG.

Abstract translation: 本公开一种服务路径改变方法和装置，包括：由MME确定UE需要从第一AG切换到第二AG; 并且由MME指示UE根据用于在第二AG和UE之间进行业务传输并由第二AG分配的承载信息通知UE的IP地址从 由第一AG分配给第二AG分配的第二IP地址的第一IP地址。 不需要将由第一AG分配给UE的第一IP地址添加到由第二AG维护的IP地址段中，并且不需要改变PDN中的路由器的路由选择信息来路由UE的下行链路数据 到第二个AG。
