Definitions

  • a cache execution entity of an embodiment of the present invention includes:
  • Step S40 When the service layer entity (AF) receives the cache control information related to the media session, the service layer entity sends a media cache request including the cache control information to the cache control entity of the bearer layer.
  • SPDF media cache request
  • the media cache request may be sent through a Diameter protocol message (Gq, interface).
  • Attribute 6 indicates that when the specified media content expiration period expires, the cache entity needs to send the request to the original server to re-enable the content before responding to the subsequent other client request; that is, when the cached content response expires, This indication requires the caching entity to perform an end-to-end revalidation operation.
  • name it "Must Reval idate (mr)."
  • the type of this parameter can be set to Boolean. Possible values include: N0, YES; The default is YES. The specific meaning is as described in the previous method.
  • the steps S50 to S52 are the same as the steps S40 to S42 described in FIG. 4, and are not described again.
  • the cache control entity sends a media cache request indication containing the authorized media cache control information to the cache execution entity on the bearer path for execution.
  • the difference from the description of step S44 in FIG. 4 is:
  • the SPDF can be extended by expanding the Diameter protocol.
  • the AVPs are used to carry the media cache request indication. For the extension and definition of the AVPs in the Diameter protocol, refer to the description of step S40 in FIG. 4, and details are not described herein.
  • the steps S60 to S62 are the same as the steps S40 to S42 described in FIG. 4, and are not described again.
  • the cache control entity sends a media cache request indication that includes the authorized media cache control information to the cache execution entity on the bearer path for execution.
  • the SPDF sends an relevant media cache request indication to the x-RACF through the Diameter request message, and the x-RACF controls the RCEF to execute the media cache policy corresponding to the media cache request indication; and after the execution is completed, The Diameter response message is replied in step S66.
  • the cache control entity 2 configured to obtain media cache control information from the service layer entity 1, and generate a media cache request indication including the media cache control information, and send the same to the cache execution entity 3;
  • the media cache request indicates the corresponding media cache policy.
  • the cache control entity 2 may further include:
  • the media cache request receiving module 20 receives a media cache request including media cache control information from the service layer, and obtains media cache control information;

Abstract

Le mode de réalisation de la présente invention porte sur un procédé de mise en œuvre d'une gestion de politique de cache dans la commande et le support de systèmes de communication séparés. Le procédé comporte les étapes suivantes : l'entité de gestion de cache émet une indication de requête de cache multimédia, qui contient des informations de gestion de cache multimédia, à l'entité d'exécution de cache; l'entité d'exécution de cache se voit ainsi indiquer d'exécuter la politique de cache multimédia correspondante. Le mode de réalisation de la présente invention porte également sur le système de mise en œuvre de gestion de politique de cache, sur l'entité de gestion de cache et sur l'entité d'exécution de cache. Le mode de réalisation de la présente invention porte ainsi sur un projet de solution simple mais efficace pour une gestion en temps de réel de politique de cache dans des sessions multimédias.
