Method and device for determining service chain for users

Abstract

The objective of the invention is to provides a method and a device for determining a service chain for users. An Sy interface between a PCRF and an OCS is enhanced, the PCRF can obtain fee information of a service chain, and an optimized service chain can be determined according to obtained fee information. The method and the device for determining a service chain for users make up gaps in the prior art, ensure that a service chain used by users are optimized in fee and save users' cost. Meanwhile, for service providers, selection of a service chain based on charging information can satisfy demands of service providers providing network service at the lowest cost so that the network operation cost is maximally reduced and a purpose of the largest output of network resources is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a technology for providing services to users. Background technique [0002] When the UE accesses the network, it will use various services in the network. When the data flow is transmitted in the network, it needs to pass through various service nodes to ensure that the network can provide users with safe, fast and stable services according to the design requirements. Internet service. When the data flow passes through these business nodes (mainly referring to security devices such as firewalls, load balancing, etc.) according to the established order required by the business logic, this is the service chain (Service Chain). Service chaining can be understood as a business form. [0003] However, in the existing LTE network, the determination and selection of the service chain is relatively static, and the influence of charging information is not considered when selecting...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing LTE network, the determination and selection of the service chain is relatively static, and the influence of charging information is not considered when selecting the service chain, which will cause the selected service chain to be difficult for operators and users. Not optimal, especially the cost

This kind of service chain selection that does not consider billing information can neither meet the needs of end users to enjoy network services at the lowest possible cost, nor can it meet the needs of operators to provide network services at the lowest cost, and cannot achieve the greatest possible reduction in network operating costs. In order to achieve the purpose of maximizing the output of network resources
