Description

终端响应触发的方法及系统、 终端、 网络侧 技术领域
本发明涉及机器类型通信 ( MTC, Machine Type Communication )终端 的管理技术, 尤其涉及一种终端响应触发的方法及系统、 终端、 网络侧。 背景技术
图 1为蜂窝无线通讯系统的结构示意图, 如图 1所示, 蜂窝无线通讯 系统主要由核心网 (CN, Core Network ), 接入网 (RAN, Radio Access Network )和终端组成。 核心网负责非接入层事务例如终端位置更新等, 核 心网同时也是用户面的锚点。 接入网包括基站, 或者包括基站以及基站控 制器, 接入网负责接入层事务例如无线资源的管理等, 基站之间可以根据 实际情况存在物理或者逻辑上的连接, 如图 1中的基站 1和基站 2、 基站 1 和基站 3之间的连接, 并且, 每个基站可以和一个以上的核心网节点连接。 终端即用户设备(UE, User Equipment ), 是指可以与蜂窝无线通讯网络通 讯的各种设备, 比如移动电话或者笔记本电脑等。
移动性管理单元(移动性管理实体( MME, Mobility Management Entity ) 或者服务 GPRS支持节点( SGSN, Serving GPRS Support Node ) )是核心网 中负责管理终端接入控制, 位置信息更新以及切换的单元, 负责核心网到 终端的非接入层信令控制以及将终端注册到网络的功能。
归属用户服务器(HSS, Home Subscriber Server )或归属位置寄存器
( HLR, Home Location Register )是核心网中负责保存用户设备的身份信息、 认证信息和授权信息等的实体。 根据不同情况, HSS或 HLR可用于保存用 户的身份信息以及用户和用户设备的绑定信息, 或仅保存用户的身份信息
(可由网关保存用户和用户设备的绑定信息), 或直接保存用户设备的身份 信息。 HSS或 HLR还负责用户的签约数据库, 以及执行用户的身份验证和 授权等。 业务平台可从 HSS或 HLR查询用户或用户设备信息。
互操作功能实体(IWF, Inter- Working Function )是设置于移动通信网 和外部公网之间的连接实体, 能够实现协议转换、 地址查询、 信息保存等 功能。 互操作功能实体对外连接应用服务器, 对内可以连接到 HSS/HLR, 或 MME/SGSN。
通常有某些业务, 比如监控管理系统需要向监控终端获取监控数据, 需要通过服务器触发终端建立与服务器的连接, 以上报需要的数据。 那么 终端在接收到服务器的触发消息后, 就需要能立即响应, 建立与服务器的 连接。 而现有技术中, 触发终端时, 网络实体需要存储服务器发送的触发 消息, 直到终端响应该触发消息并建立与服务器的连接后, 才删除存储的 该终端的触发消息。 但终端请求消息连接到网络的信令中并没有携带是否 是响应触发消息的指示, 这样, 终端请求消息连接到网络的信令, 也有可 能是因为有其他业务而触发的。 如果网络实体不能得到正确的指示, 可能 会再次发送触发消息给终端, 造成终端重复发送信令, 浪费网络资源。 发明内容
有鉴于此, 本发明的主要目的在于提供一种终端响应触发的方法及系 统、 终端、 网络侧, 网络侧能根据接入请求消息中携带的触发标识确定该 接入请求消息是对哪个触发消息作出的响应, 从而在确定终端接入到服务 器后删除自身存储的该触发消息。

步驟 1、 当 MTC应用服务器需要从终端获取实时数据时, 将触发消息 发送到移动性管理单元(MME/SGSN )。 该触发消息中包含终端的标识, 触 发指示的有效时间, 服务器的地址等信息。
步驟 2、 MME/SGSN接收到触发消息后, 根据触发消息中的终端的标 识构建寻呼消息, 寻呼该终端;
寻呼终端过程是, MME/SGSN构建寻呼消息, 寻呼消息中包含终端的 触发消息和寻呼时刻参数, 并将寻呼消息发送给基站。 然后基站根据寻呼 时刻参数计算寻呼时刻, 并在寻呼时刻在寻呼信道上发送寻呼消息。 在终 端侧, 寻呼时刻参数预先配置在终端中, 终端按照与基站相同的计算方法 计算寻呼时刻, 并在寻呼时刻在寻呼信道上读取寻呼消息。
步驟 3、 终端接收到寻呼消息后, 读取寻呼消息中的触发消息, 向 MME/SGSN发起附着请求消息,并在附着请求消息中设置一个布尔型参数, 这里参数名称为 "触发标识", 并将 "触发标识"参数的值设置为 "TRUE"。
这里, "TRUE" 即是指示用于标识触发消息的, 而不是因响应其他业 务而发送的附着请求消息。 本示例中, 假设终端在设定时段内接收到的触 发消息为一个。 即其他服务器未在设定时段内同时发起对该终端的触发消 步驟 4、 MME/SGSN在接收到终端的附着请求消息后, 读取附着请求 消息中的 "触发标识" 信息, 如果该值设置为 "TRUE" , 意味着是对触发 消息的响应消息, 则删除本地保存的该终端的触发消息。
步驟 5、如果终端不是因为触发消息而发起附着请求消息, 则在附着请 求消息中将参数 "触发标识" 的值设置为 "FALSE"。
实施例二
步驟 1、 当 MTC应用服务器需要从终端获取实时数据时, 将触发消息 发送到移动性管理单元(MME/SGSN )。 该触发消息中包含终端的标识, 触 发指示的有效时间, 服务器的地址。
步驟 2、 MME/SGSN接收到触发消息后, 根据触发消息中的终端的标 识构建系统消息, 在广播信道上广播;
构建系统消息过程是, MME/SGSN将触发消息发送到基站, 基站将触 发消息添加到现有的系统消息块中, 或者生成新的系统消息块, 然后将系 统消息块承载在广播信道上发送。
步驟 3、 终端读取广播信道上的系统消息, 读取其中的触发消息, 向 MME/SGSN发起业务请求消息,并在业务请求消息中设置一个布尔型参数, 这里参数名称为 "触发标识", 并将 "触发标识"参数的值设置为 "TRUE"。 步驟 4、 MME/SGSN在接收到终端的业务请求消息后, 读取业务请求 消息中的 "触发标识" 信息, 如果该值设置为 "TRUE" , 则删除本地保存 的该终端的触发消息。
步驟 5、如果终端不是因为触发消息而发起业务请求消息, 则在业务请 求消息中将参数 "触发标识" 的值设置为 "FALSE"。
实施例三
步驟 1、 当 MTC应用服务器需要从终端获取实时数据时, 将触发消息 发送到移动性管理单元(MME/SGSN )。 该触发消息中包含终端的标识, 触 发指示的有效时间, 服务器的地址。
步驟 2、 MME/SGSN接收到触发消息后, 通过非接入层(NAS )信令 将触发消息发送给终端。
通过 NAS信令发送过程如下:
MME/SGSN在 "DOWNLINK GENERIC NAS TRANSPORT"这条 NAS 信令中包含触发消息, 发送给终端;
步驟 3、 终端接收到 "DOWNLINK GENERIC NAS TRANSPORT" 信 令后, 读取其中的触发消息, 向 MME/SGSN发起分组数据网络连接请求消 息或分组数据协议上下文建立请求消息, 并在分组数据网络连接请求消息 或分组数据协议上下文建立请求消息中设置一个布尔型参数, 这里参数名 称为 "触发标识", 并将 "触发标识" 参数的值设置为 "TRUE"。
步驟 4、 MME/SGSN在接收到终端的分组数据网络连接请求消息或分 组数据协议上下文建立请求消息后, 读取分组数据网络连接请求消息或分 组数据协议上下文建立请求消息中的 "触发标识" 信息, 如果该值设置为 "TRUE" , 则删除本地保存的该终端的触发消息。
步驟 5、如果终端不是因为触发消息而发起分组数据网络连接请求消息 或分组数据协议上下文建立请求消息, 则在附着请求消息中将参数 "触发 标识" 的值设置为 "FALSE"。
实施例四
本示例适用于在设定时段内, 终端接收到了两个以上的触发消息, 这 里, 设定时段主要是指, 终端接收到触发消息和向网络侧响应该终端的接 入请求消息的一般处理时长, 该时段长度可由网络系统运营商根据实际情 况配置, 这里不再给出具体的手段设置值。
当在设定时段接收到的触发消息为两个以上时, 仅凭是否是对触发消 息的响应的标识, 网络侧将不能确定接入请求消息是针对哪个触发消息作 出的响应, 因此, 需要设置业务标识或触发指示标识等能分辨出不同触发 消息的标识, 供网络侧识别并删除对应的接入请求消息。
步驟 1、 当 MTC应用服务器需要从终端获取实时数据时, 将触发消息 发送到移动性管理单元(MME/SGSN )。 该触发消息中包含终端的标识, 业 务标识或触发指示标识, 触发指示的有效时间, 服务器的地址。
在这里, 业务标识或触发指示标识能够唯一的标识当前的触发消息, 用于终端可以区别来自不同服务器的触发消息。 因此, 只要是能具备相同 功能的标识, 都可以作为这里所述的业务标识或触发指示标识的替代标识。
步驟 2、 MME/SGSN接收到触发消息后, 通过非接入层( NAS )信令 将触发消息发送给终端。
通过 NAS信令发送过程如下:
MME/SGSN在 "DOWNLINK GENERIC NAS TRANSPORT"这条 NAS 信令中包含触发消息, 发送给终端;
步驟 3、 终端接收到 "DOWNLINK GENERIC NAS TRANSPORT" 信 令后, 读取其中的触发消息, 向 MME/SGSN发起分组数据网络连接请求消 息或分组数据协议上下文建立请求消息, 并在分组数据网络连接请求消息 或分组数据协议上下文建立请求消息中设置一个结构型参数, 这里参数名 称为 "触发标识", 其结构如下:
触发指示 {
是否触发 布尔型;
触发标识 字符型;
} , 并将 "触发指示" 中的 "是否触发" 项的值设置为 "TRUE" , "触 发标识" 项的值设置为接收到的触发消息中的业务标识或触发指示标识。
步驟 4、 MME/SGSN在接收到终端的分组数据网络连接请求消息或分 组数据协议上下文建立请求消息后, 读取分组数据网络连接请求消息或分 组数据协议上下文建立请求消息中的 "触发标识"信息, 如果其中参数 "是 否触发" 值为 "TRUE" , 则删除本地保存的该终端的触发消息中业务标识 与标识中的 "触发标识" 项匹配的那条触发消息。
步驟 5、如果终端不是因为触发消息而发起分组数据网络连接请求消息 或分组数据协议上下文建立请求消息, 则在附着请求消息中将参数 "触发 标识" 中的 "是否触发" 的值设置为 "FALSE" , "触发标识" 项设置为空。
实施例五
步驟 1、 当 MTC应用服务器需要从终端获取实时数据时, 发送触发消 息给 HSS或 HLR或 IWF, HSS或 HLR或 IWF在本地保存该触发消息, 并 将触发消息发送到移动性管理单元( MME/SGSN )。 该触发消息中包含终端 的标识, 触发指示的有效时间, 服务器的地址。
步驟 2、 MME/SGSN接收到触发消息后, 通过非接入层(NAS )信令 将触发消息发送给终端。
通过 NAS信令发送过程如下:
MME/SGSN在 "DOWNLINK GENERIC NAS TRANSPORT"这条 NAS 信令中包含触发消息, 发送给终端; 步驟 3、 终端接收到 "DOWNLINK GENERIC NAS TRANSPORT" 信 令后, 读取其中的触发消息, 向 MME/SGSN发起分组数据网络连接请求消 息或分组数据协议上下文建立请求消息, 并在分组数据网络连接请求消息 或分组数据协议上下文建立请求消息中设置一个布尔型参数, 这里参数名 称为 "触发标识", 并将 "触发标识" 参数的值设置为 "TRUE"。
步驟 4、 MME/SGSN在接收到终端的分组数据网络连接请求消息或分 组数据协议上下文建立请求消息后, 读取分组数据网络连接请求消息或分 组数据协议上下文建立请求消息中的 "触发标识" 信息, 如果该值设置为 "TRUE" ,则发送触发成功消息给 HSS或 HLR或 IWF, HSS或 HLR或 IWF 在本地删除响应的触发消息。
步驟 5、如果终端不是因为触发消息而发起分组数据网络连接请求消息 或分组数据协议上下文建立请求消息, 则在附着请求消息中将参数 "触发 标识" 的值设置为 "FALSE"。
