1.1eMLPP
用户需求的发展和来自其他运营商的挑战，要求现在的GSM网络不仅仅能提供语音、数据等标准业务，还能提供其他富有特色的个性化业务，eMLPP是实现此目的的一个很好的功能。
EMLPP主要是通过为特定的用户群提供较高的服务质量，这些用户通常是高端用户，他们占用户数的比例不高，但为运营商带来了业务的大部分收入，提高他们的满意度和忠诚度是稳定和提高业务收入的重要手段。
EMLPP功能简要说明
EMLPP允许在呼叫建立，呼叫延续时提供不同级别的权限,它可以为紧急呼叫提供高的服务等级，允许呼叫的优先级,允许呼叫的优先级控制
手机用户可以在呼叫建立或启动一个补充业务时提供优先级信息
无线资源的预清空；为高优先级用户强拆被叫方的通话
EMLPP支持的优先级有7种：
A，B，0-4。
在呼叫建立时，MSC根据用户的EMLPP的值来确定此次呼叫的优先级
在MSC中需要为每个eMLPP优先级定义一些参数。
在MSC与BSC交互的信道分配请求（ASSIGNMENTREQUEST）和切换请求（HANDOVERREQUEST）中要包括PCI、PVI两个参数
PCI（Pre-emptionCapabilityIndicator），PCI=1表明此连接可以拆除其他连接；
PVI（Pre-emptionVulnerabilityIndicator），PVI=1表明此连接可以被高优先级连接
请求拆除
