Description

触发消息计数器的更新方法、 机器类型通信服务器和终端
技术领域
本发明涉及终端通信领域, 尤其涉及一种触发消息计数器的更新方法、 机器类型通信服务器和终端。 背景技术
如图 1所示,蜂窝无线通讯系统主要由核心网(Core Network,简称 CN )、 无线接入网( Radio Access Network, 简称 RAN )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, 并且是用户面的锚点。 接入网包括基站, 或者基站以及基站控制, 接入网负责接入层事务(例如无线资源的管理) , 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 3之间的连接, 并且每个基站可以和一个或者一个以上的核 心网节点连接。 终端即用户设备 ( User Equipment, 简称 UE )是指可以和蜂 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。
下面对该系统中的网元进行介绍:
移动性管理单元(移动性管理实体( MME )或通用无线分组业务( GPRS ) 服务支持节点 (SGSN )或移动交换中心 (MSC )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 令控制和将终端注册到网络。
归属用户服务器 (HSS )是核心网中负责保存终端设备的身份信息、 认 证信息和授权信息等的实体。 根据不同情况, HSS可用于保存用户的身份信 息及用户和终端设备的绑定信息, 或只保存用户的身份信息 (可由网关保存 用户和终端设备的绑定信息) , 或直接保存终端设备的身份信息。 HSS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 查询用户或终端信息。
机器类型通信 ( Machine Type Communication, MTC ) 一互操作功能实体 ( IWF ): 移动通信网和外部公网之间的一个连接实体, 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 MTC服务器, 对内可 以连接到 HSS, 或 MME/SGSN/MSC等移动通信网络网元。
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, 并建立与服务器的连接。 目前为了满足服务器对终端的触发需求, 已有解决方案试图通过在触发消息 中包含触发请求的计数器, 使得终端能够检测重复的触发请求、 并关联触发 请求的确认消息, 亦使得服务器能够撤销触发请求。
然而, 在现有技术中, 还未有服务器和终端能正确设置和更新触发消息 计数器的机制, 这必然造成终端或服务器错误地对触发消息进行检测、 响应 或撤销, 以致终端触发失败或者网络存储资源的浪费。 发明内容

下面从 MTC服务器和终端交互的角度对本发明的技术方案进行详细描 述:
实施例一
该实施例中不含触发尝试计数器, 触发消息计数器的更新方法包括: 步骤 101、 MTC服务器与终端开机后,分别在本地设置触发消息计数器, 具体设置方式如下:
MTC 服务器在本地设置触发序列号计数器 ( TSC-S , Trigger
Sequence-number Counter - Server ) , 并初始化 TSC-S的值为 0, TSC-S的取 值范围是(0, 216-1 ) ;
MTC 终端在在本地设置触发序列号计数器 ( TSC-U , Trigger Sequence-number Counter - UE ) , TSC-U的取值范围是( 0, 216-1 ) 。
需要说明的是:
当服务器成功发送一条终端触发消息后, 将计数器 TSC-S的值加 1 ; 当 TSC-S的值为时 216-1时, 若再一次成功发送一条终端触发消息, 则计数器归 零, 从零开始重新计数, 周而复始; 当终端成功接收一条终端触发消息后, 读取触发消息中的触发请求计数 器, 并根据该触发请求计数器中包含的触发序列号在本地设置计数器 TSC-U 的值。
步骤 102、 当 MTC服务器需要从终端获取实时数据时, 将终端的触发消 息发送到 MTC-IWF;
触发消息中包含终端的标识, 应用的标识, 服务器的地址, 触发请求的 有效期周期, 以及触发请求的计数器。 所述终端的标识为网络之外使用的外 部标识。 所述触发请求计数器包含触发序列号。
需要说明的是, 触发序列号为触发序列号计数器 TSC-S的值, 而本条终 端触发消息为服务器对终端的第一次触发请求, 故此时, 计数器 TSC-S的值 为 0。
步骤 103、 MTC-IWF本地数据库存储了外部标识与内部标识之间的一对 一映射表,以及内部标识与短消息服务中心( SMS-SC )之间的多对一对应表。
MTC-IWF解析触发消息,根据本地数据库中存储的外部标识与内部标识的映 射表, 查找触发消息中的终端标识对应的在网络中使用的内部标识, 如国际 移动用户识别码 (IMSI ) , 并根据内部标识在数据库中存储的内部标识与 SMS-SC的对应表查找终端所在的 SMS-SC。 之后, MTC-IWF使用终端内部 标识替代原触发消息中的终端外部标识, 构建新的触发消息, 并通过触发请 求信令发送到 SMS-SC;
新的触发消息中包含触发序列号, 以及由 MTC-IWF提供的终端路由信 息, 即终端的服务 MME和 /或 SGSN和 /或 MSC的地址。
步骤 104、 SMS-SC在接收到触发请求信令后, 解析并存储其中包含的触 发消息, 构建携带触发消息的短消息, 即触发消息作为该短消息的一个信息 元, 并根据触发消息中的终端路由信息通过 MME和 /或 SGSN和 /或 MSC发 送该短消息给终端。 若终端成功接收触发消息, 则执行步骤 105A-107A; 否 则, 执行步骤 105B-106B;
步骤 105A、 终端在接收到短消息后, 读取其中包含的触发消息, 并根据 触发消息中的触发序列号在本地设置计数器 TSC-U的值。 同时, 发送触发确 认消息到 SMS-SC, 通知 SMS-SC触发消息成功发送; 确认消息中包含触发 序列号, 以及终端的标识;
需要说明的是, 当终端在本地检测到触发消息中的触发序列号与计数器 TSC-U的值相同 (或小于) 时, 丟弃该终端触发消息。 步骤 106A、 SMS-SC在接收到确认消息后 , 读取其中包含的终端标识和 触发序列号, 移除对应的终端触发消息, 并发送确认消息到 MTC服务器, 通 知 MTC服务器触发消息成功发送;
步骤 107A、 MTC服务器在接收到确认消息后, 读取其中包含的终端标 识和触发序列号, 移除对应的终端触发消息, 并将对应的计数器 TSC-S的值 加 1。
步骤 105B、 SMS-SC根据触发消息中的有效期周期在本地检测到触发消 息过期时,移除该终端触发消息,并通过触发确认消息通知 MTC服务器终端 触发消息发送失败, 确认消息中包含触发序列号, 以及终端的标识;
步骤 106B、 MTC服务器在接收到确认消息后, 读取其中包含的终端标 识和触发序列号,可选地撤销或重发该终端触发消息,且对应的计数器 TSC-S 的值不变。
上述步骤 105A和 105B可以统称为步骤 105,上述步骤 106A和 106B可 以统称为步骤 106。
实施例二
该实施例中不含触发尝试计数器, 触发消息计数器的更新方法包括: 步骤 201至步骤 202与具体实施例一中的步骤 101至步骤 102对应相同。 步骤 203、 MTC-IWF本地数据库存储了外部标识与内部标识之间的一对 一映射表, 以及内部标识与移动性管理单元(MME/SGSN/MSC )之间的多对 一对应表。 MTC-IWF解析触发消息,根据本地数据库中存储的外部标识与内 部标识的映射表, 查找触发消息中的终端标识对应的在网络中使用的内部标 识, 如 IMSI, 并根据内部标识在数据库中存储的内部标识与移动性管理单元 的对应表查找终端所在的移动性管理单元; 之后, MTC-IWF使用终端内部标 识替代原触发消息中的终端外部标识, 构建新的触发消息, 并通过触发请求 信令发送到 MME和 /或 SGSN和 /或 MSC; 触发消息中包含触发序列号; 步骤 204、 移动性管理单元在接收到触发请求信令后, 解析并存储其中 包含的触发消息, 并根据触发消息中的终端标识查询本地数据库以获得该终 端的状态, 如果该终端处于空闲状态, 则移动性管理单元发送寻呼消息给终 端, 终端接收到寻呼消息后发送业务请求信令给移动性管理单元请求建立与 移动性管理单元的非接入层(NAS )连接。 在 NAS连接建立完成后, 移动性 管理单元将从 MTC-IWF 接收到的触发消息封装在 NAS 信令下行链路 ( Downlink ) NAS传输( transport ) 中, 即触发消息作为该 NAS信令的一个 信息元发送给终端; 如果该终端处于连接状态, 则移动性管理单元直接将触 发消息封装在 NAS信令 Downlink NAS transport中, 发送给终端。 若终端成 功接收触发消息, 则执行步骤 205Α-207Α; 否则, 执行步骤 205Β-206Β;
步骤 205Α、 终端在接收到 NAS信令后, 读取其中包含的触发消息, 并 根据触发消息中的触发序列号在本地设置计数器 TSC-U的值。 同时, 发送触 发确认消息到移动性管理单元, 通知移动性管理单元触发消息成功发送; 确 认消息中包含触发序列号, 以及终端的标识;
步骤 206A、 移动性管理单元在接收到确认消息后, 读取其中包含的终端 标识和触发序列号,移除对应的终端触发消息,并发送确认消息到 MTC服务 器, 通知 MTC服务器触发消息成功发送;
步骤 207A、 MTC服务器在接收到确认消息后, 读取其中包含的终端标 识和触发序列号, 移除对应的终端触发消息, 并将对应的计数器 TSC-S的值 加 1。 触发消息过期时,移除该终端触发消息,并通过触发确认消息通知 MTC服务 器终端触发消息发送失败。 确认消息中包含触发序列号, 以及终端的标识。
步骤 206B、 MTC服务器在接收到确认消息后, 读取其中包含的终端标 识和触发序列号,可选地撤销或重发该终端触发消息,且对应的计数器 TSC-S 的值不变。
上述步骤 205A和 205B可以统称为步骤 205,上述步骤 206A和 206B可 以统称为步骤 206。
实施例三
该实施例中包含触发尝试计数器, 触发消息计数器的更新方法包括: 步骤 301、 MTC服务器与终端开机后, 分别在本地设置触发计数器, 具 体设置方式如下:

MTC服务器在本地设置触发尝试计数器( TAC, Trigger Attempt Counter ), 并初始化 TAC的值为 0, TAC的取值范围是(0, 5 ) ;
MTC终端在在本地设置触发序列号计数器 TSC-U, TSC-U的取值范围是 ( 0, 216-1 ) 。
需要说明的是, 当服务器每尝试一次发送同一条(同一触发序列号)终 端触发消息后,将计数器 TAC的值加 1;若此条终端触发消息发送尝试成功, 且服务器发起了下一条(下一触发序列号)终端触发消息的发送尝试, 则计 数器 TAC清零, 从零开始重新计数; 当计数器 TAC的值为 5时, 若再一次 尝试发送此条终端触发消息并且发送失败, 则服务器撤销此触发请求, 并在 服务器发起了下一条终端触发消息的发送尝试时, 将计数器 TAC清零, 从零 开始重新计数。
步骤 302、 当 MTC服务器需要从终端获取实时数据时, 将终端触发消息 发送到 MTC-IWF;
触发消息中包含终端的标识, 应用的标识, 服务器的地址, 触发请求的 有效期周期, 以及触发请求的计数器。 所述终端的标识为网络之外使用的外 部标识。 所述触发请求计数器包含触发序列号。
需要说明的是, 本次为此条终端触发消息的第一次发送尝试, 故此时, 计数器 TAC的值为 0。
步骤 303至步骤 306与实施例一中的步骤 103至步骤 106对应相同; 步骤 307A、 MTC服务器在接收到确认消息后, 读取其中包含的终端标 识和触发序列号, 移除对应的终端触发消息, 并将对应的计数器 TSC-S的值 加 1 ; 对应的计数器 TAC的值不变;
步骤 307B、 若 MTC服务器选择重发该终端的触发消息, 则对应的计数 器 TSC-S的值不变, 将对应的计数器 TAC的值加 1。 上述步骤 307A和 307B可以统称为步骤 307。
需要说明的是, 本次为此条终端触发消息的第二次发送尝试, 故此时, 计数器 TAC的值为 1。 当服务器在本地检测到欲尝试发送的终端触发消息对 应的计数器 TAC的值为 5时, 撤销该终端触发消息; 当服务器发起下一条终 端触发消息的发送尝试时, 将对应的计数器 TAC的值清零, 从零开始重新计 数。
