Title (EN) ENHANCED GPRS INTEGRITY BIT AND CROSS-LAYER INDICATIONS
(FR) BIT D'INTÉGRITÉ GPRS AMÉLIORÉ ET INDICATIONS INTER-COUCHES
Abstract:
(EN) An electronic communication device of a telecommunications system receives a message containing an integrity mode bit and an integrity protection bit from another electronic communication device, and determines whether the integrity protection bit indicates that a Frame Check Sequence, FCS, field of the message has been replaced by a Medium Access Control, MAC, field. Responsive to determining that the integrity protection bit indicates that the FCS field has been replaced by the MAC field, the device determines whether the MAC field is valid. Responsive to determining that the MAC field is not valid and the integrity mode bit having a first defined value, the message is discarded. Responsive to determining that the MAC field is not valid and the integrity mode bit having a second defined value, content of the message is provided to a higher network protocol layer for processing.
(FR) L'invention concerne un dispositif de communication électronique d'un système de télécommunication qui reçoit un message contenant un bit de mode d'intégrité et un bit de protection d'intégrité à partir d'un autre dispositif de communication électronique, et détermine si le bit de protection d'intégrité indique ou non qu'un champ de séquence de vérification de trame (FCS) du message a été remplacé par un champ de contrôle d'accès au support (MAC). En réponse à la détermination du fait que le bit de protection d'intégrité indique que le champ FCS a été remplacé par le champ MAC, le dispositif détermine si le champ MAC est ou non valide. En réponse à la détermination du fait que le champ MAC n'est pas valide et en réponse au bit de mode d'intégrité ayant une première valeur définie, le message est supprimé. En réponse à la détermination du fait que le champ MAC n'est pas valide et en réponse au bit de mode d'intégrité ayant une seconde valeur définie, le contenu du message est fourni à une couche de protocole de réseau supérieure pour un traitement.
