Abstract

The present disclosure pertains to improved communication quality of service (QoS) in communication networks. Higher service tiers may guarantee that a specific vocoder or bit rate is used. They may also guarantee that communication is supported by such parameters as maximum allowed dropped calls rate, maximum allowed jitter and maximum allowed latency. Network availability may be guaranteed per Service Level Agreements that are the part of the contract between a subscriber and a service provider. The network may also afford high end devices higher voice quality by comparing a given high end device to a look up table, which indicates what level of service is associated with that device. A calling device or a receiving device may ask the other device to change to a more robust vocoder or bit rate to ensure higher quality communication. Furthermore, the quality level may be adjusted before or during a call.
