Definitions

  • Embodiments disclosed herein generally relate to wireless communications and, for example to methods, apparatus and systems for network selection and configuration enabling remote provisioning, for example of subscription information.
  • Certain networks can be implemented in which user equipment is pre-configured with subscription information.
  • a wireless transmit receive unit may scan available provisioning access networks and store a list of provisioning access networks. The WTRU may then select a network from a list of provisioning access networks and transmit a registration message to the selected network. Further, the scanning may include reading an indicator in the broadcast system information, wherein the indicator includes a provisioning access network identifier (ID). Also, the registration message may include a WTRU ID and default credentials. The WTRU may further undergo an authentication procedure with a provisioning server. Moreover, if an authorization is successful, the WTRU may receive a registration accept message from the selected network. Further, the registration accept message may include a home network ID and other information. Also, the WTRU may receive a registration reject message, including the home network ID.
  • ID provisioning access network identifier
  • the WTRU may then compare the home network ID with a network ID. If the home network ID and the network ID are the same, the WTRU may transmit a protocol data unit (PDU) session establishment message to the selected network. Further, the WTRU may receive subscription data. If the home network ID and the network ID are different, the WTRU may transmit a de-registration message to the selected network and transmit a registration message to a home network. [0006] Also, if the authorization is not successful, the WTRU may receive a registration reject message from the selected network. Further, the WTRU may select another network from the list of provisioning access networks.

Abstract

La présente invention concerne un appareil et des procédés destinés à la sélection d'un réseau. Dans un exemple, une unité de réception d'émission sans fil (WTRU) peut balayer des réseaux d'accès de mise en service disponibles et stocker une liste de réseaux d'accès de mise en service. La WTRU peut ensuite sélectionner un réseau à partir d'une liste de réseaux d'accès de mise en service et transmettre un message d'enregistrement au réseau sélectionné. En outre, le balayage peut comprendre la lecture d'un indicateur dans les informations de système de diffusion, l'indicateur comprenant un identificateur de réseau d'accès de mise en service (ID). De plus, le message d'enregistrement peut comprendre un identificateur de WTRU et des justificatifs d'identité par défaut. La WTRU peut en outre subir une procédure d'authentification avec un serveur de mise en service. De plus, si une autorisation est réussie, la WTRU peut recevoir un message d'acceptation d'enregistrement de la part du réseau sélectionné. En outre, le message d'acceptation d'enregistrement peut comprendre un ID de réseau domestique et d'autres informations. De plus, la WTRU peut recevoir un message de rejet d'enregistrement, comprenant l'ID de réseau domestique.
