背景技术Background technique
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，人与人之间可以更加快捷地沟通，信息的交流也更顺畅。然而，目前仅仅是计算机和其他一些互联网技术(IT，Internet Technology)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。The emergence and development of communication network technology has brought great changes to the face of social life. People can communicate more quickly and communicate more smoothly. However, at present, only computers and other Internet Technology (IT) devices have such communication and network capabilities, and a large number of ordinary machines have little networking and communication capabilities. These are not common to networking and communication capabilities. Machine equipment includes: home appliances, vehicles, vending machines, factory machinery and equipment.

M2M mainly refers to the real-time data exchange between machines and machines through the wireless network to transmit information to the back-end server network, that is, machine interconnection and intercommunication. M2M is the general term for all technologies that enhance the communication and networking capabilities of machine equipment. The goal of M2M technology is to enable networking and communication capabilities for all machines.
M2M使得机器、设备、应用处理过程与后台信息***共享信息，并与操作者共享信息。它提供了设备实时地在***之间、远程设备之间或与个人之间建立无线连接，从而提供传输数据的手段。M2M技术综合了数据采集、全球定位***(GPS，Global Positioning System)、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***，能够使业务流程自动化，集成公司IT***和非IT设备的实时状态，并创造增值服务。这一平台可在安全监测、自动抄表、机械服务和维修业务、自动售货机、公共交通***、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 enables machines, devices, and application processes to share information with back-end information systems and share information with operators. It provides a means for transmitting data in real time by establishing a wireless connection between systems, between remote devices, or between individuals. M2M technology integrates data acquisition, Global Positioning System (GPS), remote monitoring, telecommunications, and information technology. It is an ecosystem of computers, networks, devices, sensors, and humans. It can automate business processes and integrate corporate IT. Real-time status of systems and non-IT devices and creating value-added services. This platform can be operated and provides a wide range of applications and solutions in environments such as safety monitoring, automatic meter reading, mechanical service and repair services, vending machines, public transportation systems, fleet management, industrial process automation, electromechanical, and urban information. Program.
M2M***主要由以下三部分构成：The M2M system is mainly composed of the following three parts:
无线终端：除常用的手机和笔记本电脑外，还包括各类型的行业应用终端；Wireless terminal: In addition to commonly used mobile phones and notebook computers, it also includes various types of industrial application terminals;

行业应用中心：是无线终端上传数据的会聚点，对分散的无线终端进行监控。 Industry Application Center: It is the convergence point of wireless terminal uploading data, and monitors distributed wireless terminals.
M2M技术具有非常重要的意义，有着广阔的市场和应用，推动着社会生产和生活方式新一轮的变革。但对于移动运营商来说可能缺乏足够的动力为M2M设备建立一张全新的网络。为了降低部署M2M网络的成本，在频谱方面，考虑动态或者半静态的重用现网的部分频谱以及应用零散频谱，以降低频谱的成本开销。M2M technology is of great significance, with a broad market and application, driving a new round of social production and lifestyle changes.

实施例一Embodiment 1
在本实施例中提供了一种终端接入方法，图1是根据本发明实施例的终端接入方法的流程图，如图1所示，该流程包括如下步骤：A terminal access method is provided in this embodiment. FIG. 1 is a flowchart of a method for accessing a terminal according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:
步骤S102，测量预先获取的小区列表中各个小区的信号质量，得到对应各个小区的信号质量测量值；Step S102, measuring signal quality of each cell in the pre-acquired cell list, and obtaining a signal quality measurement value corresponding to each cell;
在本发明的一个优选实施例中，本发明实施例提供的终端接入方法适用于机器类通信(Machine-Type Communications，简称MTC)，其中，MTC设备至少包括：家电、车辆、自动售货机、工厂的机器设备等；并且，本发明实施例提供的终端接入方法适用于网络侧服务器、MTC设备、非MTC设备及各个小区构成的通信网络，其中，网络服务器可以为多个网络服务器组成的服务器集群，MTC设备与非MTC设备通过接入小区与网络服务器建立通信连接。In a preferred embodiment of the present invention, the terminal access method provided by the embodiment of the present invention is applicable to Machine-Type Communications (MTC), where the MTC device includes at least: a home appliance, a vehicle, a vending machine, The device and the like of the factory; and the terminal access method provided by the embodiment of the present invention is applicable to a network side server, an MTC device, a non-MTC device, and a communication network formed by each cell, wherein the network server may be composed of multiple network servers. In the server cluster, the MTC device and the non-MTC device establish a communication connection with the network server through the access cell.
例如，本发明实施例以MTC设备为例进行说明，其中MTC设备以自动售货机为例进行说明，自动售货机为接入小区，通过小区与供应商服务器建立通信连接，以便供应商通过该自动售货机接入的网络，根据接收到的自动售货机反馈的信息对该自动售货机进行控制，因此，自动售货机为了与供应商的服务器建立通信连接，则在建立通信连接之前，通过预先获取的小区列表，测量该小区列表中各个小区的信号质量。 For example, the embodiment of the present invention is described by taking an MTC device as an example. The MTC device is described by taking a vending machine as an example. The vending machine is an access cell, and a communication connection is established between the cell and the provider server, so that the supplier passes the automatic. The vending machine accesses the vending machine according to the received feedback from the vending machine. Therefore, in order to establish a communication connection with the supplier's server, the vending machine obtains the communication connection before obtaining the communication connection. The cell list measures the signal quality of each cell in the cell list.
假设小区列表中有3个小区，分别为小区A、小区B和小区C，对应的自动售货机测量到的小区A的信号质量测量值为A1、自动售货机测量到的小区B的信号质量测量值为B1和自动售货机测量到的小区C的信号质量测量值为C1，具体如表1所示：It is assumed that there are 3 cells in the cell list, which are cell A, cell B and cell C respectively. The signal quality measurement value of cell A measured by the corresponding vending machine is A1, and the signal quality measurement of cell B measured by the vending machine is measured. The value of the signal quality measured by B1 and the cell C measured by the vending machine is C1, as shown in Table 1:
表1Table 1
小区Community 信号质量测量值Signal quality measurement
小区ACommunity A A1A1
小区BCommunity B B1B1
小区CCell C C1C1
步骤S104，依据预先获取的信号质量门限修正参数，修正各个小区所需的信号质量门限，得到修正后的各个小区所需的信号质量门限；Step S104, correcting a signal quality threshold required by each cell according to the pre-acquired signal quality threshold correction parameter, and obtaining a corrected signal quality threshold of each cell;
在本发明实施例中，该信号质量门限修正参数为网络侧服务器配置的，并由网络服务器下发至MTC设备、非MTC设备及各个小区。In the embodiment of the present invention, the signal quality threshold correction parameter is configured by the network side server, and is sent by the network server to the MTC device, the non-MTC device, and each cell.
仍旧以MTC设备为例，MTC设备根据网络服务器发送的信号质量门限修正参数修正各个小区所需的信号质量门限，得到修正后的各个小区所需的信号质量门限，例如：信号质量门限修正参数以±3为例，假设小区列表中有3个小区，分别为小区A、小区B和小区C，对应的小区A的所需的信号质量门限为A2、小区B的所需的信号质量门限为B2和小区C的所需的信号质量门限为C2；Still taking the MTC device as an example, the MTC device corrects the signal quality threshold required by each cell according to the signal quality threshold correction parameter sent by the network server, and obtains the corrected signal quality thresholds of each cell, for example, the signal quality threshold correction parameter is As an example, it is assumed that there are three cells in the cell list, namely cell A, cell B, and cell C. The required signal quality threshold of the corresponding cell A is A2, and the required signal quality threshold of cell B is B2. And the required signal quality threshold of cell C is C2;
修正过程如下：The correction process is as follows:
修正后的A3＝A2±3；The corrected A3=A2±3;
修正后的B3＝B2±3；和Corrected B3=B2±3; and
修正后的C3＝C2±3。The corrected C3 = C2 ± 3.
具体如表2所示：The details are shown in Table 2:
表2Table 2
Figure PCTCN2015079325-appb-000001
Figure PCTCN2015079325-appb-000001
步骤S106，依据修正后的各个小区所需的信号质量门限，与各个小区的信号质量测量值进行比较；Step S106, comparing with the signal quality thresholds of the respective cells according to the corrected signal quality thresholds of the respective cells;
步骤S108，选取信号质量测量值大于修正后的小区所需的信号质量门限的小区；Step S108, selecting a cell whose signal quality measurement value is greater than a signal quality threshold required by the corrected cell;
在一个优选实施例中，步骤S108结合步骤S106，仍旧以步骤S102与步骤S104中的表1与表2中的数据为例进行说明，将表1中的数据与表2中的数据进行比较，选取信号质量测量值大于修正后的小区所需的信号质量门限的小区，即，假设A1>A3、B1<B3、C1<C3，则选取小区A。In a preferred embodiment, step S108 is combined with step S106, and the data in Table 1 and Table 2 in step S102 and step S104 are still taken as an example to compare the data in Table 1 with the data in Table 2. A cell whose signal quality measurement value is larger than a signal quality threshold required by the corrected cell is selected, that is, assuming that A1>A3, B1<B3, C1<C3, the cell A is selected.
步骤S110，向选取得到的小区发送接入请求，并接入选取得到的小区。Step S110: Send an access request to the selected cell, and access the selected cell.
在本发明实施例中，仍旧以上述步骤中的自动售货机为例进行说明，自动售货机向小区A发送接入请求，并接入该小区A。In the embodiment of the present invention, the vending machine in the above steps is still taken as an example, and the vending machine sends an access request to the cell A and accesses the cell A.
本发明实施例中的MTC设备均为具备通信功能的设备，通过小区与供应商的服务器建立连接。MTC设备除通信功能外还包括存储功能及数据处理功能。本发明实施例仅以自动售货机为例进行说明，以实现本发明实施例提供的终端接入方法为准，具体不做限定。The MTC devices in the embodiments of the present invention are all devices having a communication function, and establish a connection between the cell and the server of the provider. In addition to the communication functions, the MTC device includes a storage function and a data processing function. The embodiment of the present invention is only described by taking a vending machine as an example, and the terminal access method provided by the embodiment of the present invention is implemented, which is not limited.
通过上述步骤，采用测量预先获取的小区列表中各个小区的信号质量，得到对应各个小区的信号质量测量值；依据预先获取的信号质量门限修正参数，修正各个小区所需的信号质量门限，得到修正后的各个小区所需的信号质量门限；依据修正后的各个小区所需的信号质量门限，与各个小区的信号质量测量值进行比较；选取信号质量测量值大于修正后的小区所需的信号质量门限的小区；向选取得到的小区发送接入请求，并接入选取得到的小区。解决了为M2M网络中的MTC设备提供网络接入技术的问题，进而达到了解决MTC设备接入网络的效果。Through the above steps, the signal quality of each cell in the pre-acquired cell list is measured, and the signal quality measurement value corresponding to each cell is obtained; the signal quality threshold required by each cell is corrected according to the pre-acquired signal quality threshold correction parameter, and the correction is obtained. The signal quality thresholds required by each of the subsequent cells are compared with the signal quality measurement values of the respective cells according to the corrected signal quality thresholds of the respective cells; and the signal quality measurement values are selected to be larger than the signal quality required by the corrected cells. a cell of the threshold; sending an access request to the selected cell, and accessing the selected cell. The problem of providing network access technology for the MTC device in the M2M network is solved, thereby achieving the effect of solving the MTC device accessing the network.
此外，非MTC设备同样适用于上述步骤S102至步骤S110中所述的方法，该非MTC设备与MTC设备在本发明实施提供的终端接入方法中的区别为：当非MTC设备接入MTC专用小区时，网络侧服务器为了保障MTC设备在MTC专有小区中所使用的频谱资源不被非MTC设备占用，将拒绝非MTC设备访问，该表现形式可以为：非MTC设备无法接入MTC专用小区，或在接入后MTC专用小区后与小区断开连接。In addition, the non-MTC device is also applicable to the method described in the foregoing steps S102 to S110. The difference between the non-MTC device and the MTC device in the terminal access method provided by the implementation of the present invention is: when the non-MTC device accesses the MTC-specific In the case of a cell, the network side server will refuse to access the non-MTC device in order to ensure that the spectrum resource used by the MTC device in the MTC private cell is not occupied by the non-MTC device, and the representation may be: the non-MTC device cannot access the MTC dedicated cell. Or disconnected from the cell after accessing the MTC private cell.
