  • BACKGROUND With the development of wireless technologies, mobile communications can not only provide traditional voice services, but also provide various multimedia applications, such as video, conference, presence services, and the like.

  • the IMS domain control network element cannot be notified in time to inform the IMS i or the control network element that the user is or should be logged out at the IMS i. This causes, in some IMS services, the user's status is incorrect.

This leads to inconsistency in the system status and may be a security risk. All of this may not be resolved until the IMS periodic re-registration expires.
  • the user can initiate re-registration and the user is logged out. However, at this time, since the IMS re-registration expires due to the IMS re-registration expiration, the IMS re-registration cannot be performed on time, and the user cannot be logged on the IMS i.

It can be seen that when the AGW releases the IP address, there is no signaling path to find the correct P-CSCF from the bottom up, and the IMS domain NE cannot be notified to perform IP address deregistration, which will result in the PS domain and the IMS domain IP address.

Abstract

L'invention concerne un procédé destiné à assurer le maintien de la cohérence d'un désenregistrement d'adresses IP de domaine PS et de domaine IMS. Selon ce procédé, dans la structure réseau de domaine PS et de domaine IMS du présent réseau central mobile, la voie de signalisation est établie par enregistrement normal et désenregistrée lorsque le désenregistrement normal se produit. Il est alors déterminé qu'une relation correspondante existe entre l'adresse IP et le domaine IMS, c'est-à-dire que le désenregistrement IMS est insuffisant, si l'AGW désenregistre l'adresse IP. Si tel est le cas, le désenregistrement IMS est réalisé de bas en haut jusqu'à la fin et l'AGW informe le PDF/PCRF, P-CSCF ou S-CSCF correspondant en vue de la mise en oeuvre du désenregistrement de la couche d'application IMS pour l'UE. Dans le cas contraire, le désenregistrement est arrêté. Ce procédé permet d'assurer le maintien de la cohérence du désenregistrement d'adresse IP de domaine PS et de domaine IMS, l'identificateur d'utilisateur IMS enregistré sur l'adresse IP pouvant également être désenregistré lorsque l'adresse IP de l'UE est désenregistrée dans le domaine PS.
