    • The present invention pertains to improved communication quality in cellular communication networks (10) and the like. A customer has the option to pay different amounts 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. 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 case 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)等中的改进的通信质量。 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的费用(S102)。 较高的服务层可以保证使用特定的声码器或比特率。 不同的层级可能与客户的记录(208)相关联,用于计费。 通过将给定的高端电话与指示与给定电话相关联的服务级别的查找表(图6)进行比较,网络(200)还可以为高端蜂窝电话提供更高的语音质量。 呼叫移动台(312)或接收移动台(302)可以将另一移动台改变为更健壮的声码器(410)或比特率(S508),以确保更高质量的电话呼叫。 此外,用户还可以选择在通话之前或期间改变质量水平。
