This book presents the architecture of two networks that make up the backbone of the telephone service VoLTE and video service ViLTE. The 4G mobile network makes it possible to construct bearers through which IP packets, containing either telephone signals (SIP, SDP) or voice or video media (RTP stream), are transported. The IMS network performs the processing of the telephone signal to provide VoLTE and ViLTE services, including call routing and the provision of additional services. Different procedures are described: the set-up and termination of a session, interconnection with third-party networks, roaming and intra-system handover. The inter-system handover PS-CS is a special case that occurs when the mobile loses 4G network coverage over the course of a session. The e-SRVCC mechanism enables continuity of the service during the switch of the telephone communication to the 2G or 3G networks. The SMS service for short messages, which is a special telephone service in itself, is provided by two structures, one relying on the IMS network, and a second on the CSFB functionality.

Les services téléphonique VoLTE (Voice over Long Term Evolution, qui réduit le temps de connexion et améliore la qualité sonore des appels) et vidéo ViLTE (Video over Long Term Evolution, qui propose une nouvelle norme pour la visiophonie) sont en train de se déployer dans le secteur de la téléphonie mobile et devraient équiper les prochaines générations de smartphones. Pour offrir ces services, deux réseaux sont utilisés : le réseau de mobiles 4G, qui permet de construire des supports (bearers) dans lesquels sont acheminés des paquets IP ; et le réseau IMS, qui effectue le traitement de la signalisation téléphonique, comprenant le routage de l’appel et la fourniture des compléments de services. Cet ouvrage détaille de façon exhaustive les caractéristiques de ces réseaux (architecture, protocoles de signalisation, fonctionnalités…) et les procédures (établissement et terminaison de session, interconnexion avec les réseaux tiers, itinérance, handover intra-système et inter-système…) mises en oeuvre pour faire fonctionner VoLTE et ViLTE.

The adoption of smartphones has had as a corollary the use of services that require streaming, such as video streaming, which is a constraint for the 4G mobile network. The integration of the network of Wi-Fi hotspots deployed by the operators adds capacity to the 4G mobile network. The use of Wi-Fi technology in carrier networks is the result of developments coordinated by the IEEE, WFA and WBA standardization bodies. For its part, the 3GPP standardization body has been working to integrate Wi-Fi technology into the 4G mobile network. The first part of this book presents the characteristics of the Wi-Fi radio interface. The different IEEE 802.11b / g / n / ac physical layers characterize the implementation in the 2.4 GHz ISM frequency bands and U- NII at 5 GHz. The MAC layer defines a number of media access procedures such as scanning, associating, or transferring data. The second part of this book deals with the architecture of the 4G network based on the Wi-Fi interface. This architecture defines several models corresponding, on the one hand, to Wi-Fi access controlled or not, On the other hand, to a handover controlled by the network or by the mobile. The integration of Wi-Fi technology resulted in a redefinition of attachment and session set-up procedures. Smartphones have the ability to activate simultaneously the two radio interfaces, LTE and Wi-Fi, which allows to direct certain services to one and / or the other of the interfaces. The ANDSF and HotSpot 2.0 functions provide the mobile with rules for network selection and traffic control to determine which traffic is to be routed to what type of interface.
