Problems solved by technology

However, when the terminal device moves from location 1 to location 2, it can be seen that the terminal device has moved out of the LADN SA at this time, but is still within the service range of the RAN. If the RAN node receives the LADN downlink Data, the LADN downlink data will still be sent to the terminal device, which will cause the LADN downlink data to still be received when the terminal device moves out of the LADN SA

Abstract

The invention discloses a communication method and device, relates to the field of communication, and solves the problem that LADN downlink data still can be received under the condition that terminalequipment is moved out of an LADN SA. The method comprises the following steps: an RAN node receives a first message from an AMF node, wherein the first message comprises designated area related information of the terminal equipment, and the designated area related information is used for indicating a designated area of the terminal equipment; when the RAN node determines that the terminal equipment is moved out of the designated area according to the designated area related information and first position information of the terminal equipment; and the RAN node sends the first position information or first indication information to the AMF node or an SMF node, wherein the first indication information is used for indicating that the terminal equipment has been moved out of the designated area. The communication method and device is suitable for a 5G communication process.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a communication method and device. Background technique [0002] The 5G system introduces the concept of Local Area Data Network (LADN). When the terminal device is in the LADN service area (LADN Service Area, LADN SA), the terminal device can access LADN, otherwise the terminal device cannot access LADN. . [0003] When there is downlink data to be sent to the terminal device in the data network (Data Network, DN) node, for example, LADN downlink data, the DN node will send the downlink data to be sent to the terminal device through the user plane function (User PlaneFunction, UPF) node The radio access network (Radio Access Network, RAN) node, and then the RAN node sends to the terminal device. [0004] However, the service scope of LADN SA and RAN nodes may be different, such as figure 1 As shown, when the terminal device is at position 1, it me...
