Abstract

一种业务资源分配方法及网络设备，其中，所述方法包括：网络侧确定机器类通信MTC设备当前待接入的业务；根据所述业务为所述MTC设备分配资源。

Description

一种业务资源分配方法及网络设备 技术领域
本文涉及但不限于移动通信技术领域，尤其涉及一种业务资源分配方法及网络设备。
背景技术
通信网络技术的出现和发展，给社会生活面貌带来了极大的变化，使得人与人之间可以更加快捷地沟通，信息的交流也更加顺畅。然而，当前仅仅是计算机和其他一些互联网技术(Internet Technology，IT)类设备具备这种通信和网络能力，而大量的普通机器设备几乎不具备联网和通信能力，这些不具备联网和通信能力的普通机器设备包括：家电、车辆、自动售货机、工厂的机器设备等。
作为机器对机器(Machine to Machine，M2M)物联网系统的一项关键技术，机器类通信(Machine-Type Communications，MTC)已成为当前一个重要的研究课题。M2M主要是指通过无线网络传递信息给后端的服务器网络来实现机器对机器的实时数据交换，也即机器之间的互联和互通。M2M技术是所有增强机器设备通信和网络能力的技术总称，M2M技术的目标是使所有机器设备都具备联网和通信能力。
M2M技术使得机器、设备、应用处理过程与后台信息系统能够共享信息，并与操作者能够共享信息，M2M技术提供了设备实时地在系统之间、远程设备之间或与个人之间建立无线连接，提供传输数据的手段。M2M技术综合了数据采集、全球定位系统(Global Positioning System，GPS)、远程监控、电信、信息技术，是计算机、网络、设备、传感器、人类等的生态系统，能够使业务流程自动化，集成公司IT系统和非IT设备的实时状态，并创造增值服务。这一平台可以在安全监测、自动抄表、机械服务和维修业务、自动售货机、公共交通系统、车队管理、工业流程自动化、电动机械、城市信息化等环境中运行并提供广泛的应用和解决方案。
M2M技术具有非常重要的意义和广阔的市场应用前景，推动着社会生产和生活方式新一轮的变革；预计未来将有相当的需求在物联网、车载网络，远程信息处理以及自动化，这些领域当前没有还没有得到广泛应用，一个主要原因是由于可靠性保障不够。那些专用系统的超可靠性是通过足够的频谱分配，并且终端数量也是有限的，相关技术在蜂窝系统中实现这种应用，不仅需要满足终端数量的要求，还需要满足在专用系统中的超可靠性要求；评价某种业务的可靠性则是通过如下参数来表示：如，传输速率、端到端时延等参数等；对于MTC业务的端到端时延定义了一个目标，是和相关技术中的商用系统相比时延要缩小5倍。
相关技术中的MTC业务资源分配方案是在接入网络接收到MTC设备的接入请求后再进行资源分配；一方面，该方案的资源分配过程消耗时间长；尤其在资源紧张的情况下，资源分配过程消耗的时间则更长；另一方面，相关技术中的MTC业务资源分配方案是在鉴权加密操作之后再进行的，由于鉴权加密过程需要MTC设备与接入安全管理设备(Access Security Management Entity，ASME)进行多次交互，因此，势必会加大业务建立的时延。

在一个可选实施例中，所述RAN可以通过广播信道或者寻呼信道向MTC设备所在的区域周期性地发送寻呼消息，并根据接收到的MTC设备标识获取对应的组应用标识，根据预先存储的组应用标识与业务的对应关系确定MTC设备当前待接入的业务，根据预先存储的组应用标识与资源信息的对应关系为所述MTC设备分配资源；
可选地，所述用户设备标识中可以用几个比特位来指示组应用标识；所述组应用标识是根据MTC设备的不同应用来划分多个组后，为每个组配置的。由于某些应用，例如传感器的应用具有较强的自相关性和互相关性，每次MTC服务器要求上报的信息均相似，因此，所需要的资源大小也具有相似性，即可将此类应用划分为同一个组，并为该组配置组应用标识；
可选地，本实施例中涉及的资源包括：信道资源和/或时隙格式。
步骤405，MTC设备接收寻呼消息，并向接入网络发送业务请求；
在一个可选实施例中，MTC设备接收到寻呼消息时，可以根据寻呼消息中携带的触发标识确定该寻呼消息为触发消息，并根据寻呼消息中的安全信息判断该寻呼消息是否合法，若该寻呼消息合法，则向接入网络发送业务请求。
步骤406，ASME根据运营策略触发鉴权加密流程；
步骤407，接入网络将资源分配信息发送至MTC设备，MTC设备与MTC服务器建立连接。
为实现上述资源分配方法，本发明实施例还提供一种网络设备，所述网络设备的组成结构，如图6所示，包括确定模块1和分配模块2；其中，
所述确定模块1，设置为确定MTC设备当前待接入的业务；
所述分配模块2，设置为根据所述业务为所述MTC设备分配资源。
在一个可选实施例中，所述确定模块1确定MTC设备当前待接入的业务包括，接收寻呼MTC设备的消息，根据所述寻呼MTC设备的消息中的MTC设备标识确定MTC设备当前待接入的业务。
在一个可选实施例中，所述确定模块1根据所述寻呼MTC设备的消息中的MTC设备标识确定MTC设备当前待接入的业务包括，根据所述寻呼MTC设备的消息中的MTC设备标识获取对应的组应用标识，根据预先存储的组应用标识与业务的对应关系确定MTC设备当前待接入的业务。
可选地，所述网络设备还可以包括发送模块，设置为将分配模块分配的资源信息发送至所述MTC设备。
可选地，所述分配模块根据所述业务为所述MTC设备分配资源。包括，根据预先存储的组应用标识与资源信息的对应关系为所述MTC设备分配资源。
本发明实施例中，所述用户设备标识中有几个比特位可以用来指示组应用标识；所述组应用标识是根据MTC设备的不同应用来划分多个组后，为每个组配置的。由于某些应用，例如传感器的应用具有较强的自相关性和互相关性，每次MTC服务器要求上报的信息均相似，因此，所需要的资源大小也具有相似性，即可将此类应用划分为同一个组，并为该组配置组应用标识。
可选地，本发明实施例中，所述资源可以包括：信道资源和/或时隙格式。
需要说明的是，在实际应用中，所述检测器确定模块1和分配模块2的功能可以采用位于网络侧的中央处理器(CPU)、或微处理器(MPU)、或数字信号处理器(DSP)、或可编程门阵列(FPGA)实现。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程 序指令来实现其相应功能。本申请不限制于任何特定形式的硬件和软件的结合。
工业实用性
本发明实施例所提供的资源分配方法及网络设备，网络侧确定MTC设备当前待接入的业务，根据所述业务为所述MTC设备分配资源。如此，可以根据MTC设备的业务预先分配对应的资源，与相关技术中接收到MTC设备的接入请求后再分配资源相比，可以有效地缩短MTC业务的初始建立时延，合理地分配MTC业务资源，提高资源的可用性。
