HLR用户跟踪

在HLR中激活用户跟踪的事件有：

a) Location updates/cancellations 位置更新/删除

b) Insert/delete subscriber data 插入/删除用户数据

c) Routing inquiry (speech and SM) 路由查询（包括话音和短讯）

d) Provide roaming number 提供漫游号

e) SS activity 补充业务操作

f) SMS: Alert service centre/Ready for SM 短消息业务：告警业务中心/准备接收短消息

在HLR中有两种过程，即Activate Home Subscriber Trace 和 Deactivate Home Subscriber Trace, 分别对应于OM-Subscriber-Tracing-Activation_req 和OM_ Subscriber_Tracing_Deactivation_req (09.02)。在HLR功能实体中相应的管理对象类为“traced Home Subscriber In HLR”, 由该管理类控制本网用户的跟踪。

IMSI：跟踪用户。

traceActivateInVlr：值域为True/False。当跟踪首次激活时被置为False；如果用户注册和漫游在本网PLMN时，HLR收到MAP_ACTIVATE_TRACE_MODE request的确认应答时，设置该值为True；如果用户不在本网中该值为False。

traceReference: 由OMC(OSF)确定的，和一个IMSI的某次跟踪相关的一个独一无二的值（2Bytes）。

traceType: 该值说明在MSC（或BSS）中运营者希望收集一个IMSI哪些激活事件的跟踪记录，它还说明了跟踪记录的类型并指示是否是有优先级跟踪（1Byte）。值域定义如下(12.08):

Trace Type:
