(EN) METHOD AND APPARATUS FOR CELLULAR INTERNET OF THINGS (CIOT) DATA TRANSFER OVER A CONTROL PLANE IN A WIRELESS COMMUNICATION SYSTEM

Abstract
(EN)
A method, apparatus, and computer program product are provided for control plane cellular Internet of Things (CIoT) data transfer in a wireless communication system. A method for control plane messaging between a first entity and a second entity in a network in which control plane messages are sent in a control plane protocol is described. The5 method can include a service request procedure whereby the 5GMM mode is changed from 5GMM-IDLE to 5GMM-CONNECTED mode. In some embodiments, if a user equipment is using EPS services with control plane CIoT EPS optimization, this procedure can be used for UE initiated transfer of user data via the control plane. In some embodiments, the method can include receiving from a user equipment (UE), at a core access and mobility 10 management function, a control plane service request message, starting a T3517 timer and enter the state 5GMM-SERVICE-REQUEST-INITIATED, and changing a 5GMM mode from a 5GMM-IDLE mode to a 5GMM-CONNECTED mode.

L'invention concerne un procédé, un appareil et un produit programme d'ordinateur pour Le transfert de données de l'Internet des objets cellulaire (CIoT) par l'intermédiaire d'un plan de commande dans un système de communication sans fil. L'invention concerne également un procédé de messagerie de plan de commande entre une première entité et une seconde entité dans un réseau dans lequel des messages de plan de commande sont envoyés dans un protocole de plan de commande. Le procédé peut comprendre une procédure de requête de service consistant à changer le mode 5GMM d'un état 5GMM-IDLE à un état 5GMM-CONNECTED. Dans certains modes de réalisation, si un équipement utilisateur utilise des services EPS avec une optimisation CIoT EPS de plan de commande, cette procédure peut être utilisée pour un transfert initié par UE de données d'utilisateur par l'intermédiaire du plan de commande. Dans certains modes de réalisation, le procédé peut consister à recevoir, de la part d'un équipement utilisateur (UE), au niveau d'une fonction de gestion de mobilité et d'accès central (10), un message de requête de service de plan de commande, à démarrer un temporisateur T3517 et à entrer dans l'état 5GMM-SERVICE-REQUEST-INITIATED, et à changer un mode 5 GMM d'un mode 5 GMM-IDLE à un mode 5GMM-CONNECTED.
