NETWORK MANAGEMENT METHOD AND CONTROLLER
First Claim
Patent Images
1. A network management method, comprising:
- when first user equipment (UE) is disconnected from a first base station, determining, by a controller based on in-network packet data network (IN-PDN) distribution information, a first IN-PDN and a first user plane gateway that are accessed by the first UE before the first UE is disconnected from the first base station, wherein the IN-PDN distribution information indicates a mapping relationship between an IN-PDN, a user plane gateway and the first UE;
determining, by the controller based on the IN-PDN distribution information, whether a second UE and a second user plane gateway exist, wherein there is a mapping relationship between the second UE and the first IN-PDN, there is a mapping relationship between the second UE and the first user plane gateway, and there is a mapping relationship between the second user plane gateway and the first IN-PDN; and
determining, by the controller based on a determining result about whether the second UE and the second user plane gateway exist, whether to update a mapping relationship between the first IN-PDN and a forwarding tunnel, a mapping relationship between the first IN-PDN and the first UE, and a mapping relationship between the first IN-PDN and a user plane gateway.

Abstract
A network management method and a controller are provided. Elastic scaling of an in-network packet data network IN-PDN is implemented when UE is migrated or detached. In addition, service continuity in a local network of the UE can still be ensured when the UE is migrated or detached, and an IN-PDN resource that is no longer used is reclaimed in time, thereby avoiding a waste of the IN-PDN resource.

11. A controller, comprising:
-
a processor; and a memory configured to store instructions which, when executed by the processor, cause the controller to; when a first user equipment (UE) is disconnected from a first base station, determine, based on in-network packet data network (IN-PDN) distribution information, a first IN-PDN and a first user plane gateway that are accessed by the first UE before the first UE is disconnected from the first base station, wherein the IN-PDN distribution information indicates a mapping relationship between an IN-PDN, a user plane gateway and the first UE, determine, based on the IN-PDN distribution information, whether a second UE and a second user plane gateway exist, wherein there is a mapping relationship between the second UE and the first IN-PDN, there is a mapping relationship between the second UE and the first user plane gateway, and there is a mapping relationship between the second user plane gateway and the first IN-PDN, and determine, based on a determining result about whether the second UE and the second user plane gateway exist, whether to update a mapping relationship between the first IN-PDN and a forwarding tunnel, a mapping relationship between the first IN-PDN and the first UE, and a mapping relationship between the first IN-PDN and a user plane gateway. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
