服务质量参数可以在每个实体的基础上改变，这是每个实体支持复杂的数据通信模式配置的关键。
Quality of service parameters can be changed based on each entity, it is key for each entity supported complex data communication mode configuration.
此外，服务质量属性可以添加到必须的配置消息中，从而进一步减小数据通信量。
Furthermore, the quality of service attribute may be added to an obligatory configuration message, thus even further reducing the data traffic.
这样有效降低了查询的数据通信量，非常适合于配置较低、信道有限的移动终端实现多媒体信息的查询。
Therefore, this method can reduce the querying data transfer and it is suitable for the low configuration and the limited channel mobile terminal to achieve the media information query.
