Abstract
A data communication system delivers voice-conferencing and video-conferencing to User Equipment (UE). A wireless communication network establishes a signaling bearer between the UE and an Internet Protocol Multimedia Subsystem (IMS). The IMS initiates a video-conference bearer for the UE over the wireless communication network. The wireless communication network exchanges video data over the video-conference bearer using Carrier Aggregation (CA). In response to a UE handover to a target wireless access node, the wireless communication network signals the IMS to convert the video-conference bearer into a voice-conference bearer based on Carrier Aggregation (CA) technology at the target wireless access node. The IMS initiates a voice-conference bearer for the UE over the wireless communication network. The wireless communication network exchanges voice data over the voice-conference bearer. After another handover, the wireless communication network and the IMS may convert the voice-conference bearer back into a video-conference bearer.
