A method comprising: establishing a wireless communication session between a mobile gateway and a mobile device in a mobile network; determining, by the mobile gateway, that the mobile device is associated with a mobile videoconferencing application, wherein the mobile videoconferencing application is capable of sending and receiving media streams; and providing, from the mobile gateway to a videoconferencing system (160, 162, 164) within a fixed network, a first set of indicators associated with the communication session, and performing policy control by the mobile gateway, the policy control including: causing the videoconferencing system within the fixed network to be configured for communicating with the mobile device, wherein the configuration is different from a configuration used by the videoconferencing system for communicating with videoconferencing end points (162, 164) within the fixed network, causing a session bearer within the mobile network to be adjusted to meet a quality of service, QoS, requirement of a videoconferencing media stream connected to the mobile device, the session bearer carrying the videoconferencing media stream, and causing a media bridge (130, 160) to process the videoconferencing media stream, wherein the videoconferencing media stream is processed by the media bridge (130, 160) using an operating mode that is different than an operating mode used for processing media streams for videoconferencing end points within the fixed network. establishing a wireless communication session between a mobile gateway and a mobile device in a mobile network; determining, by the mobile gateway, that the mobile device is associated with a mobile videoconferencing application, wherein the mobile videoconferencing application is capable of sending and receiving media streams; and providing, from the mobile gateway to a videoconferencing system (160, 162, 164) within a fixed network, a first set of indicators associated with the communication session, and performing policy control by the mobile gateway, the policy control including: causing the videoconferencing system within the fixed network to be configured for communicating with the mobile device, wherein the configuration is different from a configuration used by the videoconferencing system for communicating with videoconferencing end points (162, 164) within the fixed network, causing a session bearer within the mobile network to be adjusted to meet a quality of service, QoS, requirement of a videoconferencing media stream connected to the mobile device, the session bearer carrying the videoconferencing media stream, and causing a media bridge (130, 160) to process the videoconferencing media stream, wherein the videoconferencing media stream is processed by the media bridge (130, 160) using an operating mode that is different than an operating mode used for processing media streams for videoconferencing end points within the fixed network. causing the videoconferencing system within the fixed network to be configured for communicating with the mobile device, wherein the configuration is different from a configuration used by the videoconferencing system for communicating with videoconferencing end points (162, 164) within the fixed network, causing a session bearer within the mobile network to be adjusted to meet a quality of service, QoS, requirement of a videoconferencing media stream connected to the mobile device, the session bearer carrying the videoconferencing media stream, and causing a media bridge (130, 160) to process the videoconferencing media stream, wherein the videoconferencing media stream is processed by the media bridge (130, 160) using an operating mode that is different than an operating mode used for processing media streams for videoconferencing end points within the fixed network.
