本发明涉及移动通信领域，尤其涉及一种寻呼优化的方法、装置及系统、存储介质。
背景技术
图1为现有技术中长期演进系统(LTE，Long Term Evolution)的总体架构示意图，如图1所示，LTE架构包括：移动管理实体(MME，Mobility Management Entity)，服务网关(SGW，Serving GetWay)，用户设备或称为终端(UE，User Equipment)和基站(eNodeB，简称为eNB)之间是UU接口，eNB和MME之间是S1-MME(S1 for the control plane)接口，eNB和SGW之间是S1-U接口，eNB之间是X2-U(X2-User plane)和X2-C(X2-Control plane)接口。在LTE中，S1-MME接口的协议栈从下往上分为以下几个协议层：L1协议，L2协议，因特网协议(IP，Internet Protocol)，流控制传输协议(SCTP，Stream Control Transmission Protocol)，S1应用协议(S1-AP，S1-Application Protocol)。在LTE中，S1-U接口的协议栈从下往上分为以下几个协议层：L1协议，L2协议，用户数据协议/因特网协议(UDP/IP)，GPRS隧道协议-用户面(GTP-U，GPRS Tunneling Protocol-User plane)。
为了给用户提供更高的业务速率并降低使用高速率服务所需的费用，同时也可以弥补已有分布式蜂窝无线通讯系统对用户家庭或办公室覆盖的不足，无线通讯网络运营商可以将基站改装成便于携带和安装的无线宽带接入设备，提供给用户放置在家庭或办公室使用。家庭基站是一种小型低功率基站，主要用于家庭和办公室等小范围室内场所。家庭基站通过室内 的电缆、DSL(Digital Subscriber Loop，数字用户专线)或光纤等有线接入设备连接到移动运营商核心网，为特定用户提供基于无线移动通信网络的接入业务(家庭基站网关架构如图2所示)，它是对现有网络部署的有效补充，能有效提高室内语音和高速数据业务覆盖。其具有很多优点，如低成本、低功率、接入简单、即插即用、节省回传、易于与现有终端兼容、能提高网络覆盖率等。
第三代伙伴组织计划(Third Generation Partnership Projects，简称为3GPP)标准组织定义的LTE(Long Term Evolution，长期演进)系统中家庭基站被称为HeNB(home eNB)。HeNB所支持的功能与eNB基本一致，HeNB与EPC(Evolved Packet Core，演进分组核心网)之间的进程和eNB与EPC之间的进程基本一致。由于HeNB的布署通常没有经过移动运营商的网络规划、覆盖范围小且数量众多，因此为了更方便的管理并支持更多数量的HeNB，在E-UTRAN(Evolved UTRAN，演进的通用陆基无线接入网)架构下，还可能在HeNB与EPC的S1连接之间引入一个新的网元——HeNB GW(Home eNB Gateway，HeNB网关)，HeNB可通过HeNB GW作为S1代理连接移动管理实体(Mobility Management Entity，简称MME)。
在现有的LTE系统下，网络可以向空闲态和连接态的UE发送寻呼，为了实现寻呼功能，MME通过UE所支持的TAI列表信息来下发寻呼消息。优化地，在家庭基站环境下，MME也可以通过UE所支持的CSG信息以及CSG接入模式信息来进一步优化寻呼消息下发范围。目前网络演进中，大量的小基站(小基站场景下双连接网关架构如图3所示)和家庭基站将被引入，由于智能手机的耗电比功能手机大很多，为了省电，智能手机进入“休眠”模式的时间更短，但是手机进入“休眠”模式之后，网络的下行数据包无法直接送到手机终端，而是要让MME发出寻呼消息(Paging)把终端从“休眠”模式中唤醒，才能发送出下行数据包。因此随着智能手机的普及， 寻呼消息会越来越多，对网络的压力越来越大。同时各种推送(Push)业务越来越多，都会导致大量的寻呼消息发送给休眠的手机终端；如果推送业务发送给体育场中的高密度人群，很有可能诱发LTE/EPC网络中的信令风暴，轻则让网元设备过载，重则会引起整个网络的瘫痪。
目前，寻呼消息是MME发给eNB的，由eNB在其覆盖范围内搜寻相关的终端，因此会占用eNB的无线资源。为了提高寻呼成功率以及终端用户的业务体验，MME需要发出大量的寻呼消息、扩大寻呼范围，但是，MME发出的寻呼消息越多，范围越大，肯定会消耗更多的无线资源。
