Title: ROUTING ISSUING METHOD AND DEVICE
Abstract:
The present application relates to the technical field of routing allocation, and specifically to a routing issuing method and device. The method comprises: a control plane network element device receives position information of a UE; on the basis of the position information, the control plane network element device determines the client IP address used by the control plane network element device for accessing a third party server; the control plane network element device uses the client IP address to send an access request message to the third party server; the control plane element receives a UE IP address allocated to the UE by the third party server on the basis of the client IP address; and, on the basis of the UE IP address and the position information, the control plane network element device determines a user plane network element device used for issuing routing to the UE. The routing issuing method and device in the embodiments of the present invention can solve the problem of the possibility of different UE being allocated the same network section routing when UE IP addresses are allocated by a third party server in a separated CU system architecture.
