Title
(EN) DISCOVERY OF A SERVICE-PROVIDING NETWORK FUNCTION
(FR) DÉCOUVERTE D'UNE FONCTION DE RÉSEAU DE FOURNITURE DE SERVICES
Abstract
(EN)
There is provided mechanisms for enabling discovery of a service-providing NF in a 3GPP communication network. A method is performed by a Network Repository Function. The method comprises registering locality information of service-providing NFs according to locality attribute of each service-providing NF. Each locality attribute comprises structured values of location information of its service-providing NF. The method comprises obtaining a request from a service-requesting NF for one of the service-providing NFs. The request specifies a preferred locality of the requested service-providing NF. The preferred locality indicates, in terms of structured values of location information, geographical location where the service- requesting NF is deployed. The method comprises identifying, out of the service-providing NFs, that service-providing NF which has a locality attribute that best matches the preferred locality, whereby the service-providing NF closest to the geographical location where the service-requesting NF is deployed is identified. The method comprises providing a response to the service-requesting NF. The response comprises the locality attribute of the identified service-providing NF, thereby enabling discovery of the service-providing NF.

L'invention concerne des mécanismes pour permettre la découverte d'une fonction de réseau de fourniture de services dans un réseau de communication 3GPP. Un procédé est exécuté par une fonction référentielle de réseau. Le procédé comprend l'enregistrement d'information de localité de fonctions de réseau de fourniture de services en fonction de l'attribut de localité de chaque fonction NF de fourniture de services. Chaque attribut de localité comprend des valeurs structurées d'information de localisation de sa fonction NF de fourniture de services. Le procédé comprend une étape comprenant l'obtention d'une requête provenant d'une fonction NF de demande de services pour une parmi les fonctions NF de fourniture de services. La demande spécifie une localité préférée de la NF de fourniture de services demandé. La localité préférée indique, en termes de valeurs structurées d'information de localisation, d'emplacement géographique où la fonction NF de de demande de service est déployée. Le procédé comprend l'identification, parmi les fonctions NF de fourniture de services, cette fonction NF de fourniture de services qui a un attribut de localité qui correspond le mieux à la localité préférée, grâce à quoi la fonction NF de fourniture de services le plus proche de l'emplacement géographique où la fonction NF de demande de service est déployée est identifiée. Le procédé comprend la fourniture d'une réponse à la fonction NF de demande de service. La réponse comprend l'attribut de localité de la fonction NF de fourniture de services identifiée, permettant la découverte de la fonction NF de fourniture de services.
