(57) Abstract:
(EN): Systems and methods are disclosed herein that provide a mechanism for a first Network Function (NF) to directly or indirectly indicate, to a second NF, a set of NFs of the same type as the first NF that support at least some of the same types of services as the first NF. In some embodiments, a method of operation of a first NF in a core network of a wireless communication system comprise providing, from the first NF to a second NF, information that directly or indirectly indicates a set of NFs of a same NF type as the first NF that support at least some of one or more types of services provided by the first NF. The set of NFs can be used by the second NF when the second NF desires to invoke a service of the first NF, e.g., when the first NF is unavailable.
(FR): L'invention concerne des systèmes et des procédés qui fournissent à une première fonction de réseau (NF) un mécanisme lui permettant d'indiquer, directement ou indirectement, à une seconde NF, un ensemble de NF du même type que la première NF, prenant en charge au moins certains des mêmes types de services que la première NF. Dans certains modes de réalisation, un procédé de fonctionnement d'une première NF dans un réseau central d'un système de communication sans fil consiste à fournir, de la première NF à une seconde NF, des informations qui indiquent, directement ou indirectement, un ensemble de NF d'un même type de NF que la première NF prenant en charge au moins certains d'un ou plusieurs types de services fournis par la première NF. L'ensemble de NF peut être utilisé par la seconde NF lorsque la seconde NF souhaite appeler un service de la première NF, par exemple lorsque la première NF n'est pas disponible.
