Definitions

  • the present disclosure relates to the field of mobile communication, in particular to 5G mobile networks. More specifically, a service based interface, SBI, for a network entity (NE), e.g. according to 5G, is provided which allows for resource management and service handling at a network function (NF) instance running at a local node.
  • SBI service based interface
  • NE network entity
  • NF network function
  • the SBI is associated with the deployed NF instances on-demand.
  • a new interface might be configured individually.
  • pre-configuration in such a way is inefficient. This becomes even more evident in case of NF instance deployment under a dynamic situation, such as when NF instances are migrated in the cloud cluster from time to time, which leads to an unnecessary coordination of their interfaces as well.
  • On-demand configuration solutions only work in a cloud environment. However, in many cases, dedicated physical devices are still widely used in many operators’ networks. Unfortunately, configuration after virtualization via a controller cannot cover the latter case.
  • the on-demand pre-configuration separates the virtualization and interface establishment into two independent steps..
  • the interface specifically configured for VM deployment decreases the opportunity of multiplexing of the interface.
  • the method further includes initiating, by the SBI, the discovery of the service or the information related to a service from at least one other network entity, if the service or the information related to a service cannot be discovered from the local NF service table.
  • FIG. 5 shows a schematic view of a method according to an embodiment of the present invention.
  • the embodiments of the present invention provide a common layer to delegate service requests of running NF instances 103.
  • a more efficient service request processing is proposed so that unnecessary service discovery can be avoided.
  • service requests from respective NF instances will be directly mapped to the network routing layer, and if the routing information is not available to an NF instance, a discovery process for the NF instance will take place.
  • the embodiments of present invention open such an information and makes it public to all local NFs, therefore, if another NF service is either prepared, found and/or proactively discovered once, this information will be available to all NFs. Therefore, to handle a service request 104, a progressive service discovery mechanism is used where it always starts with a local matching and search.

Abstract

La présente invention se rapporte du domaine de la communication mobile, et en particulier aux réseaux mobiles 5G. Une interface basée sur un service, SBI, associée à une entité de réseau (101) est fournie. La SBI (100) est configurée pour identifier une ressource locale (102) de l'entité de réseau (101) et au moins une fonction de réseau, NF, locale, (103) de l'entité de réseau (101) ; pour obtenir une demande de service (104) à partir d'une NF locale (103) ; pour découvrir un service (105) et/ou des informations relatives à un service (106) sur la base de la demande de service (104) ; pour traiter la demande de service (104) sur la base d'au moins un élément parmi : une priorité de la demande de service (104), le service découvert (105) et/ou des informations relatives à un service (106), et la ressource locale identifiée (102) et au moins une NF (103) locale.
