Embodiment Construction

[0123] figure 1 It is a schematic diagram of a possible application scenario of this application. Such as figure 1 As shown, the system includes a UE, an access network (English: Access Network, abbreviated: AN) network element, a user plane (English: User Plane, abbreviated: UP) network element, a control plane (English: Control Plane, abbreviated: CP) network element and service network.

[0124] figure 1 The system shown is a system in which the UP network element and the CP network element are separated from each other. For example, in a possible design, the original PGW is split into PGW-C and PGW-U, the original SGW is split into SGW-C and SGW-U, and PGW-C and SGW-C can be collectively referred to as CP network In actual deployment, PGW-C and SGW-C can be deployed independently or integrated; PGW-U and SGW-U can be collectively referred to as UP network elements. In actual deployment, PGW-U and SGW- U can be deployed independently or integrated into one. exist fig...

Abstract

The present application relates to the technical field of route distribution, and in particular to a method and device for delivering routes. The method includes: a control plane network element device receives location information of a user equipment UE; the control plane network element device determines a client IP address used by the control plane network element device to access a third-party server according to the location information; 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 network element device receives the third-party server according to the client IP address. An allocated UE IP address; the control plane network element device determines a user plane network element device for delivering a route to the UE according to the UE IP address and the location information. The method and device for delivering routes in the embodiments of the present invention can solve the problem that different UEs are allocated the same network segment routes that may occur when the UE IP address is allocated by a third-party server under the CU separation system architecture.

Description

technical field [0001] The present application relates to the technical field of route distribution, and in particular to a method and device for delivering routes. Background technique [0002] When user equipment (English: User Equipment, UE for short) accesses the system network, the system needs to assign an IP address to the UE, and publish a route for the UE to access the network according to the IP address of the UE. [0003] In a typical communication system, that is, a communication system in which the control plane (English: Control Plane, CP for short) and the user plane (English: User Plane, UP for short) are integrated together, the PGW or the first The third-party server assigns an IP address to the UE. In the case where the third-party server assigns an IP address to the UE, the PGW sends a request message to the third-party server, and the request message carries the IP address of the PGW as the client of the third-party server. (referred to as PGWIP address...
