Title
(EN) ROBUST HEADER COMPRESSION INDICATION AFTER PATH SWITCH DURING HANDOVER
(FR) INDICATION ROBUSTE DE COMPRESSION D'EN-TÊTE APRÈS COMMUTATION DE TRAJET PENDANT UN TRANSFERT INTERCELLULAIRE
Abstract
(EN)
Systems, methods, and devices are provided to: perform packet data convergence protocol (PDCP) deciphering of the packets to store deciphered packets in a common buffer; perform PDCP reordering of the deciphered packets in the common buffer to generated a stream or reordered packets; perform robust header compression (ROHC) decompression on the stream of reordered packets; and determine, based on a packet indication, to reset the ROHC decompression, wherein the packet indication comprises a single bit in a PDCP header set to indicate a start of ROHC reset based on a path switch during a handover from a source cell to a target cell.
(FR)
L'invention concerne des systèmes, des procédés et des dispositifs pour : effectuer le déchiffrement des paquets selon le protocole de convergence de données par paquets (PDCP) pour stocker les paquets déchiffrées dans un tampon commun; effectuer un réordonnancement PDCP des paquets chiffrés dans le tampon commun pour générer un flux ou des paquets réordonnés; effectuer une décompression ROHC (compression d'en-tête robuste) sur le flux de paquets réordonnés; et déterminer, sur la base d'une indication de paquet, de réinitialiser la décompression ROHC, l'indication de paquet comprenant un seul bit dans un ensemble d'en-tête PDCP pour indiquer un début de réinitialisation ROHC basé sur un changement de chemin pendant un transfert d'une cellule source à une cellule cible.
