Definitions

  • downlink indicates communication from the BS to the MS
  • uplink indicates communication from the MS to the BS.
  • a method of enabling a mobile station to perform initialization to a base station in a wireless communication system includes synchronizing with the base station, obtaining an uplink parameter based on the synchronization, performing initial ranging by using the uplink parameter and establishing security association between the mobile station and the base station while performing the initial ranging.
  • a method of performing initial ranging in a wireless communication includes receiving a first ranging request message, transmitting a first ranging response message indicating that ranging process is successful, receiving a second ranging request message including a mobile station public key for ciphering and transmitting a second ranging response message including a base station public key in response to the second ranging request message.
  • a method of performing initial ranging in a wireless communication system includes transmitting a first ranging request message, receiving a first ranging response message indicating that ranging process is successful, transmitting a second ranging request message including a certificate and receiving a second ranging response message including a temporary session key, wherein the temporary session key is ciphered through a public key in the certificate.
  • a method of performing initial ranging in a wireless communication system includes receiving a ranging request message including a certificate, generating a temporary session key through a public key in the certificate and transmitting a ranging response message including the temporary session key.

Abstract

L'invention concerne un procédé qui permet à une station mobile d'effectuer une initialisation L'invention se rapporte à une station de base dans un système de communication sans fil. Le procédé consiste à: synchroniser avec la station de base; obtenir un paramètre de liaison montante basé sur la synchronisation; effectuer un réglage initial à l'aide du paramètre de liaison montante; et établir une association de sécurité entre la station mobile et la station de base au cours du réglage initial. Au cours du réglage initial, un identifiant unique ou une signalisation de commande de la station mobile peut être transmis(e) en toute sécurité.
