    • The present invention pertains to improved communication quality of service (QoS) in cellular communication networks (10) and the like. A customer has the option to pay different fees for different tiers of service relating to voice quality and bandwidth access (S102). 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 (Table 1). Network availability may be guaranteed as per Service Level Agreements that are the part of the contract between a subscriber and a service provider. Different tiers may be associated with customers' records (208) for billing purposes. The network (200) may also afford high end cellular phones higher voice quality by comparing a given high end phone to a look up table (FIG. 6), which indicates what level of service is associated with the given phone. A calling mobile station (312) or a receiving mobile station (302) may ask the other mobile station to change to a more robust vocoder (410) or bit rate (S508) to ensure a higher quality phone call. Furthermore, the user may also opt to change the quality level before or during a call.
    • 本发明涉及蜂窝通信网络(10)等中的改进的通信服务质量(QoS)。 客户可以选择为与语音质量和带宽访问相关的不同层次的服务支付不同费用(S102)。 较高的服务层可以保证使用特定的声码器或比特率; 他们还可以保证通信由最大允许掉话率,最大允许抖动和最大允许延迟等参数支持(表1)。 可以根据作为订户和服务提供商之间的合同一部分的服务级别协议来保证网络可用性。 不同层级可能与客户的记录(208)相关联,用于计费。 网络(200)还可以通过将给定的高端电话与查找表(图6)进行比较来为高端蜂窝电话提供更高的语音质量,该查询表指示与给定电话相关联的服务级别。 呼叫移动台(312)或接收移动台(302)可以要求另一移动台改变为更稳健的声码器(410)或比特率(S508),以确保更高质量的电话呼叫。 此外,用户还可以选择在呼叫之前或期间改变质量水平。
