Definitions

  • the present disclosure is generally related to mobile communications and, more particularly, to setting a follow-on request indicator in mobility registration update (MRU) for unavailability period in mobile communications.
  • MRU mobility registration update
  • a user equipment In wireless communications such as mobile communications under the current 3 rd Generation Partnership Project (3GPP) specification, a user equipment (UE) is required to set a follow-on request indicator in MRU to "No follow-on request pending" when indicating unavailability (UA) information to a network. This is a valid requirement when the UA period is activated right after the completion of the MRU procedure. However, if the UE informs the network about a start of the UA period and the activation of the unavailability period will happen at a later point in time, then it would be unreasonable to prevent the UE from using the established signaling connection for another payload as well. Due to this, the UE would not be able to reuse the existing signaling connection for additional data or signaling payloads.

Abstract

L'invention concerne des techniques se rapportant au réglage d'un indicateur de demande de suivi dans une mise à jour d'enregistrement de mobilité (MRU) pour une période d'indisponibilité dans des communications mobiles. Un appareil (par exemple, un UE) transmet un message à un réseau informant le réseau d'une période d'indisponibilité. Sur la base du message transmis au réseau, qui ne comprend pas l'heure de début de la période d'indisponibilité, l'appareil effectue une ou plusieurs opérations, notamment le réglage d'un indicateur de demande de suivi sur « aucune demande de suivi en attente ».
