A method for centralized oam resource allocation in 5gs

Abstract

The invention discloses a method, device and system for centralized OAM resource allocation in 5GS, which are suitable for an OAM resource allocation end, including receiving a request message sent by a sending end, wherein the request message includes at least an OAM function supported by a network function entity NF; According to the OAM function supported by the network function entity NF, the network function entity NF is allocated a separate and isolated virtual OAM resource; if the allocation is successful, a corresponding request success message is sent to the sender. The technical scheme of the present invention allows the OAM resource allocation end to allocate individual OAM resources isolated by virtualization containers for each network function entity NF.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for centralized OAM resource allocation in 5GS. Background technique [0002] 5G mobile networks are expected to better support diverse communication services, service models and end-user groups. In order to provide independent network services for various services without laying a dedicated network separately, the 5G network introduces network slicing technology to schedule the entire network layer resources in units of network slices. This technology virtualizes physical infrastructure resources into multiple independent parallel network slices. Each network slice subnet realizes logical isolation in equipment, access network, transmission network and core network, and each network slice serves A specific business scenario to meet the differentiated requirements of different business scenarios on bandwidth, delay, and service quality, so as to meet the di...

Problems solved by technology

However, the OAM of each NF uses the overall public resources on the centralized OAM entity, and does not allocate independent OAM resources for a certain NF. In this case, once a problem occurs in the OAM of one NF, it will affect the entire NF. OAM operation in 5GS

[0004] If the existing virtualization container (NFV) technology is used to allocate an OAM virtual resource to a NF, although the OAM of each NF can be isolated to reduce the impact of faults between the OAMs of each NF, but now according to TS 3GPP The protocol standard does not have a specific process and specification for dynamically allocating dynamic OAM resources for each NF. If static allocation of NF resources is adopted, manual operation is required for each allocation and release of virtual OAM resources, resulting in low network flexibility and network management efficiency. not tall
