<p>Prior reservation of bandwidth is enabled during conference setup. Through synchronization of directory databases at one or more multi-modal communication application deployment sites and use of a multi-modal communication enabled node at an evolved packet core (EPC), bandwidth is statically or dynamically allocated for communication sessions based on requesting user profile, requested modality, location of the user, and similar factors such that a desired Quality of Service (QoS) is maintained during the communication session. Service Providers (SPs) provide differentiated QoS by pre-reserving bandwidth margin over and above what is required. The bandwidth margin is used by the SPs to include additional error correction mechanism. Dynamic bandwidth allocation factors in the location of the UC devices and roaming status.</p> |
