CA 2535899
Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice- versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to- Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.
La présente invention concerne des techniques de transmission améliorant la continuité de service et réduisant les interruptions de remise des contenus imputables aux transitions intervenant lorsque l'équipement utilisateur passe d'une cellule à une autre, ou lorsque la remise des contenus abandonne une connexion point à point pour prendre une connexion point à multipoint dans la même cellule de desserte, et réciproquement. Ces techniques de transmission permettent une remise sans solution de continuité des contenus d'une frontière de cellule à l'autre et/ou entre différentes logiques de transmission telles que le point à multipoint et point à point. L'invention concerne également des mécanismes permettant de caler différentes séquences et de récupérer les contenus de chacun des blocs de données pendant de telles transitions, évitant ainsi les pertes de données pendant les transitions. L'invention concerne enfin des mécanismes permettant de recaler les données pendant le décodage au terminal récepteur.
