Title (EN) APPARATUS AND METHODS FOR MODEM ASSISTED VIDEO TELEPHONY
(FR) APPAREIL ET PROCÉDÉS DE TÉLÉPHONIE VIDÉO ASSISTÉE PAR MODEM
Abstract:
(EN) Aspects of the present disclosure provide an apparatus and method for modem-assisted video telephony. As one example, a user equipment (UE) utilizes a modem to perform video telephony (VT) communication with a remote device through a wireless network. The UE determines a network metric indicative of congestion in the wireless network based on modem information obtained from the modem, independent of feedback information received from the remote device. The UE dynamically adjusts a data rate of the VT communication by an amount proportional to a quantity based on the network metric.
(FR) Dans ses modes de réalisation, la présente invention se rapporte à un appareil et à un procédé de téléphonie vidéo assistée par modem. Dans un exemple, un équipement d'utilisateur (UE) utilise un modem pour exécuter une communication en téléphonie vidéo (VT) avec un dispositif distant, via un réseau sans fil. L'UE détermine une mesure réseau indiquant un encombrement dans le réseau sans fil, sur la base d'informations de modem obtenues du modem, indépendamment de données de rétroaction reçues du dispositif distant. L'UE ajuste de façon dynamique un débit de données de la communication VT d'une quantité proportionnelle à une quantité basée sur la mesure de réseau.
