Description

信息的发送、 转发方法及装置
技术领域 本发明涉及物联网通信领域, 具体而言, 涉及一种信息的发送、转发方法及装置。 背景技术 机器到机器 (Machine to Machine, 简称为 M2M) 通信技术指机器之间建立连接 的所有技术和手段。对 M2M通信应用场景研究表明在移动网络上提供 M2M通信具有 潜在的市场前景。 但 M2M业务对系统提出了很多新的要求, 为了增强移动网络在这 方面的竞争力, 有必要对现有的移动网络进行优化, 来更有效的支持 M2M通信。 现有的移动通信网络主要针对人与人的通信进行设计, 而对机器与机器, 人与机 器的通信则优化不足。此外,运营商如何能够以低成本提供 M2M通信服务,也是 M2M 通信部署成功的关键。 基于以上情况, 有必要研究移动网络支持 M2M通信的解决方案, 解决方案要最 大限度重用现有网络, 降低大量 M2M通信对网络造成的影响以及运营维护的复杂度。 目前电信市场竞争日趋激烈, 资费不断下降, 运营商利润空间不断减小, 以人为 基础的通信市场正在趋于饱和, M2M对运营商来说是全新的发展机遇。 一个由多家标准组织组成的联盟日前成立了一个新的全球组织 oneM2M, 以确保 机器到机器 (M2M) 通信系统的有效部署。 M2M 是物联网的支撑技术, 可以让未来 的智能城市成为现实。 它允许各种电子设备通过可连接无线感应器和移动互联网的 SIM卡相互通信, 用于管理、 监控和服务提供。 全球 M2M的连接数量正呈现指数级 增长态势, 庞大的连接数量预计可以分布于几乎所有主要的市场中: 从医疗、 运输、 能源到农业等等。 由 oneM2M制定的标准规范提供了通用 M2M服务层, 该层可嵌入 各类硬件和软件中, 并可连接现场的无数设备。 该组织将为 M2M制定全球端到端规 范, 目的在于降低成本、 缩短产品上市时间、 创建规模经济、 简化应用开发, 以及避 免标准重叠等。 这一联盟由七家标准组织所构成, 这些组织都在研究制定技术规范和 报告, 以确保 M2M设备可以成功地在全球范围内实现通信。 0neM2M的系统架构目 前还在讨论中, 其概念示意图如图 1所示。 oneM2M的上层协议架构如图 2所示。 物联网要真正实现全球的互联互通, 标准化是亟需解决的重要问题, 而要将各种 物体连接到网络中, 并实现物与物、 物与系统、 物与人之间的通信以及基于此的各种 应用, 首先必须对物联网涉及的各种实体进行高效、 唯一的标识。 标识是一种自动识 别各种物联网物理和逻辑实体的方法,识别之后才可以实现对物体信息的整合和共享、 对物体的管理和控制、 对相关数据的正确路由和定位, 并以此为基础实现各种各样的 物联网应用。 物联网主要采用赋予性标识。 赋予性标识是为了识别方便而人为分配的标识, 如 物品编码、 手机号、 互联网协议 (Internet Protocol, 简称为 IP)地址等, 通常由数字、 字母等符号按照一定编码规则组合而成, 相对基于自然属性的本质性标识, 赋予性标 识形式简单易于保存、 读取和处理, 是现阶段物联网中标识的主要形式。 物联网中有物理实体、通信实体和应用实体三种类型的对象需要标识。物理实体: 是指在实现对信息的获取、 传递和处理以及对物的控制等各种物联网应用和管理的过 程中, 要与网络发生联系的任何物体。 如各种传感器、 执行器、 贴有标签的物体 (如 动物、 货物、 食品) 以及各种智能装置 (如数码产品、 家用电器) 等。 通信实体: 是 物与物、 物与系统、 物与人通信过程中涉及到的各种通信硬件实体和逻辑实体。 硬件 实体包括手机、 M2M网关等, 逻辑实体比如通信协议、 会话、 端口等。 应用实体: 是 指物联网中涉及的各种服务和信息资源, 如 Web服务、 数字内容、 聚合数据等物体标 识主要标识物联网三类需标识对象中的物理实体和通信硬件实体。 基于条码和射频标识(Radio Freqency Identification, 简称为 RFID)标签的物体标 识主要用于实现对物体的辨别、 信息追溯、 信息交换和关联操作等, 主要适用于非智 能物体, 如集装箱、 食品等。 通信标识用于标识与信息数据传送和交换相关的逻辑实 体, 主要目的是寻址, 实现信息的正确路由和定位, 这些逻辑实体包括通信协议、 会 话、 端口等, 比如 IP 地址、 E.164 号码、 国际移动用户识别码 (International Mobie Subscriber Identity, 简称为 IMSI) 号码、 会话启动协议 (Session Initiation Protocol, 简称为 SIP)统一资源标识符 (Uniform Resource Identifier, 简称为 URI)各类端口号 等。应用标识主要标识物联网中的各类应用实体,包括各种服务和信息资源等,如 URI、 ContentID等。 物联网中的通信标识和应用标识通常存储在计算机和其他智能设备中, 而物体标识则需要存储在特定的载体中, 在使用前通过特定技术写入, 并在需要时利 用相应技术读出。 物联网在标识方面, 与传统互联网及电信网相比, 急需解决的问题 重点主要集中在物体标识, 其次是通信标识。 物联网大规模分布式的特点, 要求必须 有一个健壮的可扩展的物体标识体系。 如何建立起兼容多种标准体系的统一物体标识 与解析体系, 如何应对物体通信对通信标识数量需求的大规模增加是物联网需要解决 的重点问题。 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,尚无有效地能够兼容多种标准体系的物体标识方案等技术问题, 本发明实施例提供了一种信息的发送、 转发方法及装置, 以至少解决上述问题。 根据本发明的一个实施例, 提供了一种信息的发送方法, 应用于 M2M通信系统, 该方法包括: 发送端设备通过通信网络向目标设备发送待发送信息, 其中, 所述待发 送信息中携带有以下之一指定标识: 第一标识, 用于在所述通信网络之外标识所述目 标设备;
