L’offload vise à décharger une partie du trafic de données des utilisateurs du réseau mobile de … Pivot Table Excel Tutorial - Duration: 13:36. In this post I intend to look at the different approaches for VoWiFi and throw in some technical details. While over-the-top (OTT) mobile communications services may also employ Wi-Fi, where possible, to prevent using a subscriber’s (licensed) data plan, this is not typically referred to as VoWiFi as these services are not tightly integrated with a MNOs global service offering and infrastructure. Ce message s’appelle une balise ou un “beacon” en anglais. D’ailleurs WiFi Calling et VoLTE partagent la même architecture de service, à savoir l’IMS, IP Multimedia Subsystem). Furthermore, the specification outlines the subset of required telephony supplementary services and the supported media types.
Tech Knowledge 109 views. Un autre scénario se profile : WiFi Calling. It based on the EPC (ePDG), SingleSDB (3GPP AAA), and IMS as the core control architecture. Huawei VoWiFi Solution The Huawei VoWiFi solution complies with 3GPP specifications and uses the EPC (ePDG), SingleSDB (3GPP AAA), and IMS as the core control architecture. The Voice over Wi-Fi (VoWiFi) service, also called Wi-Fi Calling, enables subscribers to use smartphones that support VoWiFi to dial numbers to initiate voice or video calls when Wi-Fi connection is available.Huawei VoWiFi solution complies with 3GPP specifications. Ce message contient plusieurs informations comme le SSID (le nom du réseau WiFi), les débits supportés par la borne, la sécurité mise en place… Ce beacon est envoyé par la borne surun et un seul canalqu’elle a choisi au préalable 2. le clie… Quand le réseau faiblit, le VoWiFi est l’une des solutions combinant le WiFi local à la 4G pour améliorer les appels et la transmission des SMS/MMS. Par ailleurs cette solution permet lauthentification par lopérateur mobile du client WiFi. L’offload du trafic de l’accès à WiFi en est une des principales raisons. Following the 3GPP reference architecture defined within the 3GPP’s TS 23.402 (Architecture enhancements for non-3GPP [IP] accesses), connectivity from the mobile handset to the evolved packet core (EPC) is over the S2b reference interface via an enhanced packet data gateway (ePDG) function. Comment se passe une association entre un client et une AP ? 4:58. Interface S6b entre le PDN GW et le 3GPP AAA server Architectures d'Accès WiFi à l'ePC et Service VoWiFi/WiFi Calling Associé . Employing VoWiFi enables MNOs (or MVNOs) to quickly and easily extend their coverage or service range without costly radio access network (RAN) infrastructure build-outs, investing in new licensed spectrum or engaging in complex roaming agreements. 4. IR.51 also specifies the basic Wi-Fi radio, IMS and EPC capabilities along with describing functionality that is applicable across the protocol stack and subsystems.
Ce scénario sappelle Carrier WiFi. Kevin Stratvert Recommended for you. A presentation from LTE World Summit 2014 by Taqua on this topic has already crossed 13K views.
7. The PRD also stipulates the use of (dual-radio) circuit switch (CS) call continuity and fallback (VCC), per 3GPP TS 23.237. Ce détournement du signal vise à répondre à la demande exponentiellement croissante de consommation de lInternet mobile. The Huawei VoWiFi solution uses untrusted WLAN access (native VoWiFi) or direct connection to IMS (VoWiFi with app). Les architectures de roaming associées sont aussi décrites. Lusager utilise le WiFi pour accéder directement à internet et le WiFi Calling pour les services de téléphonie et SMS avec son opérateur mobile. 13:36 .
