Description

驻留处理方法及装置
技术领域 本发明涉及通信领域, 具体而言, 涉及一种驻留处理方法及装置。 背景技术 集群通信系统是为了满足行业用户指挥调度需求而开发的、 面向特定行业应用的 专用无线通信系统, 系统中大量无线用户共享少量无线信道, 以指挥调度为主体应用, 是一种多用途、 高效能的无线通信系统。 具有特有的调度、 组呼以及快速呼叫等特性, 已经成为下一代集群系统的发展方向。 长期演进 (Long-Term Evolution, 简称为 LTE) 集群通信系统, 是在 LTE系统的 基础上实现集群的各种需求和功能。 LTE的演进分组交换中心 (Evolved Packet Core, 简称为 EPC) 核心网和集群的分布式系统服务 (Distribution System Service, 简称为 DSS) 核心网, 组网架构上做到业务完全隔离, 集群应用的组网, 不依赖于 LTE EPC 设备的布置, 不影响已有 LTE EPC核心网设备, 做到专网隔离, 公网共享。 集群系统信息的读取方式复用原有 LTE公网的实现方式,对支持集群通信的小区, 在系统信息块 (System Information Block, 简称为 SIB) 1 (即 SIBl ) 的调度信息列表 里面添加集群专用的 SIB19、 SIB20的指示。 其中, SIB19主要用于广播集群相关的公 共配置, SIB20主要用于指示该小区系统支持的能力。 基于集群采用单独布网的方式, 集群的公众陆地移动电话网 (Public Land Mobile Network,简称为 PLMN)列表是按小区配置的 PLMN列表下发的,而 LTE公网的 SIB1 中的 PLMN列表是按有效的 PLMN下发的。如果将集群的 PLMN列表也通过 SIB1下 发, 将不便于区分空口 SIB1中的 PLMN是属于 S1的还是 T1的或者 S1/T1共用的。 这样在终端进行驻留判断时, 由于无法区分 PLMN的来源, 只能判断出当前集群小区 是否适合驻留, 而不能正确得出应该到 EPC上注册还是到按下通话 (Press-To-Talk, 简称为 PTT)调度服务器(PTT Dispatch Server, 简称为 PDS)上注册, 影响注册成功 率。 针对相关技术中的上述问题, 目前尚未提出有效的解决方案。 发明内容 针对相关技术中,由于无法区分 PLMN来源而导致的注册成功率较低等技术问题, 本发明实施例提供了一种驻留处理方法及装置, 以至少解决上述问题。 根据本发明的一个实施例, 提供了一种驻留处理方法, 包括: 在支持集群通信的 小区, 将非接入层 (Non-Access Stratum, 简称为 NAS) 下发的第一 PLMN列表与第 二 PLMN列表进行匹配, 其中, 所述第二 PLMN列表携带于所述小区配置的指定 SIB 中;
