Title:
IP ADDRESS POOL MANAGEMENT METHOD IN 5G SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/218294
Kind Code:
A1
Abstract:
A solution provided in the present invention is based on a next-generation 5G network architecture, takes into consideration a system in which an access network and a core network are merged, or in which at least some network elements of a core network is moved down to an access network. Primarily considered is a uRLLC scenario, in order to reduce end-to-end delay and, at the same time, to satisfy the reliability of data transmission, some network elements (such as a GW, comprising an S/P-GW) of the core network is moved down to the access network; as such, the access network is provided with discrete IP address management and assignment capabilities and a routing function; however, one direct impact of moving down the GW is that the management of an IP address pool is different from that of a conventional LTE network. The primary difference is embodied in that a next-generation 5G network dynamically creates sliced networks on an NFV/SDN basis, and because sliced networks in an access network need to be created and deleted in real-time as required, the impact brought forth is that network elements in each sliced network are created and deleted as required. Therefore, the assignment of the IP address pool of the GW is dynamically managed as required, comprising dynamic creation, dynamic assignment, adjustment, reclamation, and so forth. The solution of the present invention sets forth a resolving method on the basis of the described architecture.
