The invention name is "A method for M2M terminal access network and M2M. The priority of the Chinese Patent Application for the communication system is hereby incorporated by reference in its entirety. Technical field

本发明涉及移动通信技术，特别是涉及一种 M2M ( Machine-to-machine, 机器间）终端接入网络的方法、一种 M2M终端、一种用于 M2M通信的基站及一种 M2M通信***。背景技术 The present invention relates to mobile communication technologies, and in particular, to a method for accessing a network by a M2M (Machine-to-machine) terminal, an M2M terminal, a base station for M2M communication, and an M2M communication system. Background technique

目前的移动通信主要是人与人（ Human to human, 筒称 H2H )之间的通信，而机器间（M2M )通信作为一种新型的通信理念，其目的是将多种不同类型的通信技术有机结合，如：机器对机器通信、机器控制通信、人机交互通信、移动互联通信，从而推动社会生产和生活方式的发展。与 H2H通信技术相比， M2M通信具有低移动性、传输数据量小、对通信时延不敏感、要求极低功耗等特征。 The current mobile communication is mainly the communication between human to human (H2H), and the inter-machine (M2M) communication is a new communication concept. Its purpose is to organically combine many different types of communication technologies. Combine, such as: machine-to-machine communication, machine control communication, human-computer interaction communication, mobile internet communication, thereby promoting social production and lifestyle development. Compared with H2H communication technology, M2M communication has the characteristics of low mobility, small amount of transmitted data, insensitivity to communication delay, and extremely low power consumption.

M2M技术是物联网实现的关键， M2M会在若干年后成为 LTE ( Long Term Evolution, 长期演进）的核心应用之一。预计未来用于 H2H通信的终端可能仅占整个终端市场的 1/3, 而更大数量的通信是 M2M通信业务。 M2M technology is the key to the realization of the Internet of Things. M2M will become one of the core applications of LTE (Long Term Evolution) in a few years. It is expected that terminals used for H2H communication in the future may only account for 1/3 of the entire terminal market, and a larger number of communications are M2M communication services.

但是，当前的移动通信网络是针对 H2H通信设计的，如网络容量的确定等，还不支持专门针对 M2M通信的功能。因此，目前的 M2M终端只能当作普通的 H2H终端来使用，不能脱离用户，即不能称之为单纯的机器间通信或者机器型通信。而且，如果 M2M与 H2H 共存于通信***中， M2M通信会与 H2H通信竟争***的传输资源，如控制信道资源、业务信道资源等，在海量 M2M终端的情况下，还会对 H2H的通信产生比较大的影响。发明内容 However, the current mobile communication network is designed for H2H communication, such as the determination of network capacity, and does not support the function specifically for M2M communication. Therefore, the current M2M terminal can only be used as a normal H2H terminal, and cannot be separated from the user, that is, it cannot be called simple inter-machine communication or machine type communication. Moreover, if M2M and H2H coexist in the communication system, the M2M communication will communicate with the H2H communication system, such as control channel resources, traffic channel resources, etc., in the case of massive M2M terminals, It will have a relatively large impact on H2H communication.

Compared with the prior art, the technical solution provided by the embodiment of the present invention has at least one of the following features:

本发明实施例提出一种通过专用小区进行 M2M通信的方法： M2M终端启动后首先驻留在初始搜索到的小区中，然后根据小区广播控制消息中指示 M2M专用小区的信息，判断初始驻留小区是否为 M2M专用小区，如果不是，则根据所述指示 M2M专用小区的信息，通过小区重选驻留到 M2M专用小区。这样， M2M终端只在 M2M专用小区进行业务传输，从而降低了 M2M通信对 H2H通信的影响；而且， M2M专用小区能够支持 M2M通信的一些特性，因此 M2M终端不再当作普通的 H2H终端使用。 The embodiment of the present invention provides a method for performing M2M communication by using a dedicated cell. After the M2M terminal starts, it first resides in the initially searched cell, and then determines the initial camped cell according to the information indicating the M2M dedicated cell in the cell broadcast control message.

下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述： The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。 The above described objects, features and advantages of the present invention will become more apparent from the detailed description.

为了利用当前的移动通信网络来支持 M2M 通信，就需要根据 M2M通信的特点对当前移动通信***的机制进行优化，以便能够在对传统的 H2H通信不受或受较小影响的情况下，更好地实现 M2M通信。 In order to utilize the current mobile communication network to support M2M communication, it is necessary to optimize the mechanism of the current mobile communication system according to the characteristics of the M2M communication, so as to be able to M2M communication is better achieved in the case where conventional H2H communication is not affected or is less affected.

基于此，本发明实施例提出一种通过专用频率层 /专用载波 /专用小区进行 M2M通信的方法，将通信网络的频率层 /载^小区划分为 M2M 专用频率层 /载波 /小区和非 M2M 专用频率层 /载波 /小区，当 M2M 终端进行小区搜索时，基站通过一种指示的方法，通知 M2M 终端***中有 M2M专用的频率层 /载波 /小区，从而使得 M2M终端只在 M2M 专用的频率层 /载波 /小区驻留以及进行业务的传输，降低 M2M对 H2H的影响。 Based on this, the embodiment of the present invention provides a method for performing M2M communication by using a dedicated frequency layer/dedicated carrier/dedicated cell, and dividing the frequency layer/carrier of the communication network into M2M dedicated frequency layer/carrier/cell and non-M2M dedicated. Frequency layer/carrier/cell, when the M2M terminal performs cell search, the base station informs the M2M terminal system that there is a frequency layer/carrier/cell dedicated to the M2M through an indication method, so that the M2M terminal only has the frequency layer dedicated to the M2M. /Carrier/cell camping and transmission of services, reducing the impact of M2M on H2H.

其中， M2M终端也称为 MTC ( Machine Type Communications, 机器型通信 )终端。 M2M专用的频率层 /载波 /小区是指专用于 M2M 通信的频率层或者载波或者小区，所述频率层（也可称为频点或频段）、载波、小区是三个相互通用的概念， M2M 专用的频率层即指 M2M专用的载波，也可指 M2M专用的小区，但是多个小区可同属于一个频率层或载波。 Among them, the M2M terminal is also called MTC (Machine Type Communications) terminal. The frequency layer/carrier/cell dedicated to M2M refers to the frequency layer or carrier or cell dedicated to M2M communication. The frequency layer (also called frequency or frequency band), carrier, and cell are three common concepts, M2M. A dedicated frequency layer refers to a carrier dedicated to M2M, and may also refer to a cell dedicated to M2M, but multiple cells may belong to one frequency layer or carrier.

本发明实施例的具体实现方法如下： The specific implementation method of the embodiment of the present invention is as follows:

参照图 1 , 是本发明实施例所述一种 M2M终端接入网络的方法流程图。 1 is a flowchart of a method for an M2M terminal to access a network according to an embodiment of the present invention.

M2M通信包括基站侧的处理和终端侧的处理，基于现有的移动通信网络，为实现 M2M通信，首先需要对基站侧进行针对 M2M的配置，所述配置包括对 M2M专用频率层 /载波 /小区的配置，以及对非 M2M 专用频率层 /载波 /小区分别的配置，配置信息主要为指示 M2M专用小区的信息，然后 M2M终端根据所述配置按照以下步骤接入通信网络： The M2M communication includes the processing on the base station side and the processing on the terminal side. Based on the existing mobile communication network, in order to implement the M2M communication, the base station side needs to be configured for the M2M, and the configuration includes the M2M dedicated frequency layer/carrier/cell. The configuration, and the configuration of the non-M2M dedicated frequency layer/carrier/cell respectively, the configuration information is mainly information indicating the M2M dedicated cell, and then the M2M terminal accesses the communication network according to the configuration according to the following steps:

步骤 101 , M2M终端启动后，驻留在初始搜索到的小区中；小区初始搜索过程指的是用户设备 (UE)启动后选择通信***中的小区接入，并取得时间和频率的同步以及检测小区 ID (即物理层小区标识）的过程。小区初始搜索是移动终端开机后首先要做的步骤，是移动终端接入小区的保证。 M2M终端开机后，在可能存在小区的几个频段上进行搜索，通过接收附近基站发出的同步信号，获得频段中小区组里的小区 ID, 并以接收信号的强弱来判断可以初始驻留的小区。 Step 101: After the M2M terminal starts, camping in the initially searched cell; the cell initial search process refers to selecting a cell access in the communication system after the user equipment (UE) starts, and acquiring synchronization and detection of time and frequency. The process of cell ID (ie, physical layer cell identity). The initial cell search is the first step after the mobile terminal is powered on, and is the guarantee for the mobile terminal to access the cell. After the M2M terminal is powered on, the search is performed on several frequency bands in which the cell may exist, and the cell ID in the cell group in the frequency band is obtained by receiving the synchronization signal sent by the nearby base station, and the initial strength of the received signal is determined by the strength of the received signal. Community.

优选的， M2M终端可以先在运营商预配置的固定频段上进行小区搜索，从而降低 M2M小区搜索的复杂度。 Preferably, the M2M terminal may first perform a cell search on a fixed frequency band pre-configured by the operator, thereby reducing the complexity of the M2M cell search.

步骤 102, 从初始驻留小区的广播中读取广播控制消息，所述广播控制消息中包含指示 M2M专用小区的信息； Step 102: Read a broadcast control message from a broadcast of an initial camping cell, where the broadcast control message includes information indicating a dedicated cell of the M2M;

M2M终端使用小区搜索过程识别并获得小区下行同步，从而可以读取小区广播信息。 M2M终端从小区广播信息中读取广播控制消息，广播控制消息中预先配置了指示 M2M 专用小区的信息， M2M 终端才艮据该配置信息就可以获知当前初始驻留的小区是否为 M2M专用小区。其中，所述指示 M2M专用小区的信息可以有多种配置方式，将在下面的内容中进行详细说明。 The M2M terminal uses the cell search procedure to identify and obtain the cell downlink synchronization, so that the cell broadcast information can be read. The M2M terminal reads the broadcast control message from the cell broadcast information, and the information indicating the M2M dedicated cell is pre-configured in the broadcast control message, and the M2M terminal can learn whether the currently camped cell is an M2M dedicated cell according to the configuration information. The information indicating the M2M dedicated cell may have multiple configurations, which will be described in detail below.

步骤 103, 根据所述指示 M2M专用小区的信息，判断所述初始驻留小区是否为 M2M专用小区； Step 103: Determine, according to the information indicating the dedicated cell of the M2M, whether the initial camping cell is an M2M dedicated cell;

如果是，则 M2M终端可以继续驻留在当前小区，接入当前小区的网络进行业务传输；如果不是，则继续步骤 104; If yes, the M2M terminal can continue to camp on the current cell, access the network of the current cell for service transmission; if not, proceed to step 104;

步骤 104, 如果所述初始驻留小区不是 M2M专用小区，则通过小区重选驻留到 M2M专用小区。 Step 104: If the initial camping cell is not an M2M dedicated cell, camp on the M2M dedicated cell by cell reselection.

M2M终端如果不能驻留在当前小区，则需要重新选择 M2M专用小区来驻留。 If the M2M terminal cannot camp on the current cell, it needs to reselect the M2M dedicated cell to camp.

综上所述，通过上述基站侧的配置以及 M2M终端在小区搜索过程中根据所述配置信息进行的判断处理， M2M 终端只驻留在 M2M 专用小区进行业务传输，从而降低了 M2M通信对 H2H通信的影响；而且， M2M专用小区能够支持 M2M通信的一些特性，因此 M2M终端不再当作普通的 H2H终端使用。 In summary, the M2M terminal only resides in the M2M dedicated cell for service transmission by the configuration of the base station side and the judgment process performed by the M2M terminal according to the configuration information in the cell search process, thereby reducing the M2M communication to the H2H communication. Moreover, the M2M dedicated cell can support some features of M2M communication, so the M2M terminal is no longer used as a normal H2H terminal.

另一方面，在 H2H终端接入网络的过程中，为了限制 H2H终端对 M2M通信的影响，还可以对 M2M 专用小区进行以下配置：在 M2M专用小区的广播控制消息中设置指示当前小区不能驻留 H2H终端的信息。这样，当 H2H终端进行小区搜索并初始驻留到 M2M专用小区时，根据该小区广播控制消息中的所述配置就可以获知当前小区是 M2M专用小区，不能进行驻留，因此需要通过小区重选选择非 M2M专用小区驻留。这样， H2H终端也不会占用 M2M通信的资源，即 H2H通信也不会影响 M2M通信。为了进一步详细说明如何在小区广播控制消息中配置指示 M2M 专用小区的信息，下面将以 LTE***为例，提供多种配置方式。 On the other hand, in the process of accessing the network by the H2H terminal, in order to limit the impact of the H2H terminal on the M2M communication, the M2M dedicated cell may also be configured as follows: In the broadcast control message of the M2M dedicated cell, the setting indicates that the current cell cannot be camped on. H2H final Information on the side. In this way, when the H2H terminal performs the cell search and initially camps on the M2M dedicated cell, according to the configuration in the cell broadcast control message, it can be known that the current cell is an M2M dedicated cell, and cannot be camped. Therefore, cell reselection is required. Select non-M2M private cell camping. In this way, the H2H terminal does not occupy the resources of the M2M communication, that is, the H2H communication does not affect the M2M communication. To further detail how to configure the information indicating the M2M private cell in the cell broadcast control message, the LTE system is taken as an example to provide multiple configurations.

目前 LTE ***定义了两类用于传输广播信息的信息块，即主信息块（MIB , Master Information Block)和***信息块（SIB， System Information Block ), 其中 MIB 在物理广播信道（PBCH, Physical Broadcasting Channel)中发送； SIB在物理下行共享信道（ PDSCH, Physical Downlink Shared Channel)中发送，高层协议中定义了多种 SIB信息块（SIB1~SIB15 )，这些 SIB信息块依靠高层协议规定的逻辑关系进行区分。 Currently, the LTE system defines two types of information blocks for transmitting broadcast information, namely, a Master Information Block (MIB) and a System Information Block (SIB), where the MIB is in a Physical Broadcasting Channel (PBCH, Physical Broadcasting). The SIB is transmitted in the Physical Downlink Shared Channel (PDSCH). The SIB information blocks (SIB1~SIB15) are defined in the upper layer protocol. These SIB information blocks are based on the logical relationship defined by the upper layer protocol. distinguish.

其中， SIB1主要用于小区选择以及小区驻留的判断； Among them, SIB1 is mainly used for cell selection and cell resident judgment;

SIB2主要用于公共信道参数和资源的配置； SIB2 is mainly used for configuration of common channel parameters and resources;

SIB3〜SIB5主要用于小区重选。 SIB3~SIB5 are mainly used for cell reselection.

目前 LTE的 MIB信息块大小确定为 24比特（ bits )，但 LTE Release 8***只使用了其中 14bits, 其余 1 Obits留作后续扩展使用，目前在 LTE Release 8中对这部分没有使用的 lObits填零处理， LTE Release 8 ***中的用户设备仅解读前 14bits，不解读该填零部分。 At present, the MIB information block size of LTE is determined to be 24 bits (bits), but the LTE Release 8 system only uses 14 bits, and the remaining 1 Obits are reserved for subsequent expansion. Currently, in the LTE Release 8, the lObits that are not used in this part are zero-filled. Processing, the user equipment in the LTE Release 8 system only interprets the first 14 bits, and does not interpret the zero padding.

现有技术中， LTE中小区能否驻留 H2H终端的配置如下：在 SIB1 消息中的参数 cellBarred用来指示当前小区是否能够驻留 H2H终端， barred表示当前小区不能驻留， notBarred表示当前小区可以驻留，具体如下所示。 H2H终端进行小区搜索的过程中，根据小区广播控制消息中的参数 cellBarred可以获知当前小区是否可以驻留，如若不能则进行小区重选。 In the prior art, the configuration of whether the cell in the LTE can camp on the H2H terminal is as follows: The parameter cellBarred in the SIB1 message is used to indicate whether the current cell can camp on the H2H terminal, the barred indicates that the current cell cannot camp, and the notBarred indicates that the current cell can Resident, as shown below. During the cell search process, the H2H terminal can learn whether the current cell can camp according to the parameter cellBarred in the cell broadcast control message, and if not, perform cell reselection.

基于现有移动通信网络的上述配置，本实施例也将在传输广播信息的信息块 MIB或 SIB中对广播控制消息配置指示 M2M专用小区的信息。 Based on the above configuration of the existing mobile communication network, the present embodiment also configures the broadcast control message with information indicating the M2M dedicated cell in the information block MIB or SIB transmitting the broadcast information.

本实施例提供了多种方法分别对 M2M专用小区和非 M2M专用小区进行配置： This embodiment provides multiple methods for configuring an M2M dedicated cell and a non-M2M dedicated cell separately:

1、对 M2M专用小区，提供了 2种配置方式： 1. Two configuration modes are provided for the M2M dedicated cell:

1.1、在 M2M专用的频率层 /载^小区的广播控制消息中增加用于指示当前小区是否能够驻留 M2M 终端的参数信息 MTC-cellBarred, 如果 MTC-cellBarred为 barred, 表示 M2M终端不能驻留；如果 MTC-cellBarred为 NotBarred, 表示 M2M终端可以驻留。如果 M2M终端检测到 MTC-cellBarred,则忽略针对 H2H终端的参数 cellBarred的设置。 1.1. Adding parameter information MTC-cellBarred for indicating whether the current cell can camp on the M2M terminal in the broadcast control message of the M2M-specific frequency layer/carrying cell, and if the MTC-cellBarred is barred, indicating that the M2M terminal cannot be camped; If MTC-cellBarred is NotBarred, it means that the M2M terminal can reside. If the M2M terminal detects MTC-cellBarred, the setting of the parameter cellBarred for the H2H terminal is ignored.

本实施例提供了 2种 MTC-cellBarred参数设置方式： This embodiment provides two types of MTC-cellBarred parameter settings:

1 )一种可选的方式是将 MTC-cellBarred消息放在 SIB1中传输，具体如下所示： 1) An optional way is to place the MTC-cellBarred message in SIB1, as shown below:

}， },

2 )另外一种可选的方式是在 MIB消息的预留比特中增加一个息域来设置 MTC-cellBarred，用以指示当前小区是否为 M2M小区，具体如下所示： 2) Another optional method is to add a region in the reserved bits of the MIB message to set the MTC-cellBarred to indicate whether the current cell is an M2M cell, as follows:

MasterlnformationB lock ::= SEQUENCE { MasterlnformationB lock ::= SEQUENCE {

基于 1.1的配置，当 M2M终端按照图 1所示流程尝试接入网络时，如果搜索到一个 M2M专用频率层 /载¾7小区，通过该小区广播控制消息中的参数 MTC-cellBarred就知道可以驻留在该小区。 Based on the 1.1 configuration, when the M2M terminal attempts to access the network according to the flow shown in FIG. 1, if an M2M dedicated frequency layer/carrier is searched, the parameter MTC-cellBarred in the cell broadcast control message is known to be campable. In the cell.

1.2、在 M2M专用频率层 /载波 /小区的广播控制消息中增加用于指示***中其他的 M2M专用频率层 /载^/小区的消息。 1.2. Add a message for indicating other M2M dedicated frequency layer/carrier/cell in the system in the broadcast control message of the M2M dedicated frequency layer/carrier/cell.

一种可选的方式是在 SIB5中增加 mtcFreqCarrierFreqList参数，用于指示当前***中其他专用于 M2M通信的频率层 /载波 /小区，具体如下所示： An optional way is to add the mtcFreqCarrierFreqList parameter to the SIB5 to indicate other frequency layers/carriers/cells dedicated to M2M communication in the current system, as follows:

替换页（细则第 26条) 如果一个 M2M专用频率层 /载波 /小区同时进行了 1.1和 1.2所述的配置，当 M2M终端按照图 1所示流程尝试接入网络时，如果搜索到该 M2M专用频率层 /载波 /小区，根据 1.1的配置获知可以驻留，根据 1.2的配置获知其他可以驻留的专用频率层 /载波 /小区，这时 M2M 终端可以通过小区重选的方式选择最优的小区驻留。 Replacement page (Article 26) If an M2M dedicated frequency layer/carrier/cell is configured as described in 1.1 and 1.2 at the same time, when the M2M terminal attempts to access the network according to the flow shown in FIG. 1, if the M2M dedicated frequency layer/carrier/cell is searched, according to The configuration of 1.1 is known to be camped. According to the configuration of 1.2, other dedicated frequency layers/carriers/cells that can be camped on are known. At this time, the M2M terminal can select the optimal cell camping by means of cell reselection.

此外，优选的，为了限制 H2H终端驻留在 M2M专用频率层 /载 ^小区，对 M2M通信造成影响，还可以在 M2M专用的频率层 /载波 /小区的广播控制消息中配置指示当前小区处于 H2H终端不能驻留的信息。一种可选的方式是通过将 SIB1中 cellBarred信息域置为 barred 状态，从而阻止 H2H终端的驻留。这时， H2H终端需要通过小区重选选择非 M2M专用小区驻留。 In addition, in order to limit the impact of the H2H terminal on the M2M dedicated frequency layer/carrier, the M2M communication may be affected, and the M2M-specific frequency layer/carrier/cell broadcast control message may be configured to indicate that the current cell is in the H2H. Information that the terminal cannot reside on. An alternative is to prevent the H2H terminal from camping by setting the cellBarred information field in SIB1 to the barred state. At this time, the H2H terminal needs to select a non-M2M dedicated cell camp by cell reselection.

2、对非 M2M专用小区，提供了 4种配置方式： 2. For non-M2M dedicated cells, four configuration modes are provided:

总的配置思路是：在非 M2M专用的频率层 /载波 /小区的广播控制消息中增加指示当前***中是否有专用于 M2M通信的专用频率层 /载波 /小区的消息。此种情况下， M2M终端可以通过小区重选的方式重新驻留在 M2M专用频率层 /载波 /小区。 The general configuration idea is: Add a message indicating whether there is a dedicated frequency layer/carrier/cell dedicated to M2M communication in the current system in the broadcast control message of the frequency layer/carrier/cell dedicated to the M2M. In this case, the M2M terminal can re-resident in the M2M dedicated frequency layer/carrier/cell by means of cell reselection.

优选的，在小区重选的过程中，如果初始驻留小区不是 M2M专用小区，还可以将所述初始驻留小区的优先级置为最低，将广播控制消息中指示的 M2M专用小区的优先级置为高，则 M2M终端进行小区重选时将选择优先级高的 M2M专用小区驻留。 Preferably, in the process of cell reselection, if the initial camping cell is not an M2M dedicated cell, the priority of the initial camping cell may be set to be the lowest, and the priority of the M2M dedicated cell indicated in the broadcast control message is to be broadcasted. When set to high, the M2M terminal will select the M2M dedicated cell with high priority to camp when performing cell reselection.

2.1、基于专用频率层 /载波的配置方式 2.1, based on the dedicated frequency layer / carrier configuration

1 ) 一种可选的方式是放在 SIB5 中，在邻频载波信息 InterFreqCarrierFreqlnfo 中增加一个标识 mtcFlag, 用于指示专用于 M2M通信的专用频率层 /载波，所述标识是一个布尔类型的变量，具体如下所示： 1) An optional way is to put in the SIB5, add an identifier mtcFlag in the adjacent frequency carrier information InterFreqCarrierFreqlnfo, for indicating a dedicated frequency layer/carrier dedicated to M2M communication, the identifier is a Boolean type variable, The details are as follows:

下面通过具体举例进行说明： The following is a specific example:

例 1: 基于 1.1和 2.1的配置示例 Example 1: Configuration example based on 1.1 and 2.1

假设通信***中有两个频率层 /载波 /小区 F1和 F2， F1用于 H2H 通信， F2用于 M2M通信，这两个频率层 /载¾7小区上的配置分别如下： Assume that there are two frequency layers/carriers/cells F1 and F2 in the communication system, F1 is used for H2H communication, and F2 is used for M2M communication. The configurations on the two frequency layer/carriers are as follows:

在 F1的广播控制消息中增加上述 2.1的配置，指示***中 M2M 专用频率层 /载波 /小区信息，可选择两种设置方法 mtcFlag 或者 mtcFreqCarrierFreqList的指示；在 F2的广播控制消息中将 cellBarred 置为 Barred, 将 MTC-cellBarred置为 notBarred, 如 1.1所述。 Adding the configuration of 2.1 above to the broadcast control message of F1, indicating the M2M dedicated frequency layer/carrier/cell information in the system, and selecting two indication methods mtcFlag or mtcFreqCarrierFreqList; setting the cellBarred to Barred in the broadcast control message of F2 , set MTC-cellBarred to notBarred, as described in 1.1.

通过这样的配置可以实现如下功能： Through such a configuration, the following functions can be realized:

对于 M2M终端： For M2M terminals:

当 M2M终端进行小区搜索并初始驻留在 F1上时，通过 F1上的广播控制消息荻知 F2是为 M2M通信专用的载波，那么 M2M终端在小区重选的过程中将 F1的优先级置为最低，同时将***广播控制消 When the M2M terminal performs cell search and initially camps on F1, the broadcast control message on F1 knows that F2 is a carrier dedicated to M2M communication, and then the M2M terminal sets the priority of F1 in the process of cell reselection. Minimum, at the same time, the system broadcast control

替换页（细则第 26条) 息中指示的 M2M专用频率层 /载波的优先级设为最高，从而通过小区重选的机制重新驻留到 F2上。 Replacement page (Article 26) The priority of the M2M dedicated frequency layer/carrier indicated in the message is set to the highest, so that it re-resident to F2 through the mechanism of cell reselection.

当 M2M终端进行小区搜索并初始驻留在 F2上时，如果检测到 MTC-cellBarred参数的设置，则忽略 cellBarred参数设置，从而驻留在 F2上。 When the M2M terminal performs cell search and initially camps on F2, if the setting of the MTC-cellBarred parameter is detected, the cellBarred parameter setting is ignored, and thus resides on F2.

对于 H2H终端： For H2H terminals:

当 H2H终端初始驻留在 F2上时，由于 F2 的 cellBarred设置为 Barred, 所以 H2H终端需要重新进行小区搜索，从而驻留在 F1上。 When the H2H terminal initially resides on F2, since the cellBarred of F2 is set to Barred, the H2H terminal needs to perform cell search again, so as to reside on F1.

当 H2H终端初始驻留在 F1上时，其操作与现有技术一致。 When the H2H terminal initially resides on F1, its operation is consistent with the prior art.

例 2: 基于 1.1、 1.2和 2.1的配置示例 Example 2: Configuration example based on 1.1, 1.2, and 2.1

假设***中有三个频率层 /载^小区 Fl、 F2和 F3, F1用于 H2H 通信， F2和 F3用于 M2M通信，那么这三个频率层 /载波 /小区上的配置分别如下： Suppose there are three frequency layers/loading cells Fl, F2 and F3 in the system, F1 is used for H2H communication, F2 and F3 are used for M2M communication, then the configurations on these three frequency layers/carriers/cells are as follows:

在 F1的广播控制消息中增加上述 2.1的配置，指示***中 M2M 专用频率层 /载波 /小区信息，可选择两种设置方法 mtcFlag 或者 mtcFreqCarrierFreqList的指示，从而致使***中的 F2和 F3是用于 M2M通信的频率层 /载^小区。 Adding the configuration of 2.1 above to the broadcast control message of F1, indicating the M2M dedicated frequency layer/carrier/cell information in the system, and selecting two indication methods mtcFlag or mtcFreqCarrierFreqList, so that F2 and F3 in the system are used for M2M. The frequency layer/carrier of the communication.

在 F2 和 F3 的广播控制消息中将 cellBarred 置为 Barred, 将 MTC-cellBarred置为 notBarred, 另外在 F2的***广播控制消息中增加 mtcFreqCarrierFreqList用于指示 F3是用于 M2M通信的频率层 /载波 /小区，同时在 F3 的系统广播控制消息中增加 mtcFreqCarrierFreqList用于指示 F2是用于 M2M通信的频率层 /载波 / 小区。从而使得 M2M终端通过小区重选的方式驻留在最优的小区中。 In the broadcast control messages of F2 and F3, set cellBarred to Barred, set MTC-cellBarred to notBarred, and add mtcFreqCarrierFreqList to F2 system broadcast control message to indicate that F3 is the frequency layer/carrier/cell for M2M communication. At the same time, mtcFreqCarrierFreqList is added to the system broadcast control message of F3 to indicate that F2 is a frequency layer/carrier/cell for M2M communication. Thereby, the M2M terminal resides in the optimal cell by means of cell reselection.

对于 M2M终端： For M2M terminals:

当 M2M终端进行小区搜索并初始驻留在 F1上时，处理流程与例 1相同，通过小区重选重新驻留到 M2M专用小区 F2或 F3上。当 M2M 终端初始驻留在 F2 上时，根据广播控制消息中的 mtcFreqCarrierFreqList可以获知***中还有 F3也是专用频率层 /载波 / 小区；同样，当 M2M终端初始驻留在 F3上时，根据广播控制消息中的 mtcFreqCarrierFreqList也可以获知***中还有 F2也是专用频率层 /载波 /小区。这时， M2M终端可以从 F2和 F3中选择一个质量最优的小区进行驻留。 When the M2M terminal performs cell search and initially camps on F1, the processing procedure is the same as that in the first example, and re-resident to the M2M dedicated cell F2 or F3 by cell reselection. When the M2M terminal initially camps on F2, it can be known from the mtcFreqCarrierFreqList in the broadcast control message that F3 is also a dedicated frequency layer/carrier/cell in the system; likewise, when the M2M terminal initially resides on F3, according to the broadcast control Message The mtcFreqCarrierFreqList in the system can also know that F2 is also a dedicated frequency layer/carrier/cell in the system. At this time, the M2M terminal can select one of the best quality cells from F2 and F3 to camp.

对于 H2H终端： For H2H terminals:

其处理与例 1相同。 The processing is the same as in Example 1.

2.2、基于专用小区的配置方式 2.2. Based on the configuration mode of the dedicated cell

在非 M2M专用频率层 /载^/小区的广播控制消息中增加指示当前频点中的 M2M专用小区的信息，以及指示相邻频点中的 M2M专用小区的信息。这样，当 M2M终端按照图 1所示流程尝试接入网络时，如果搜索到一个非 M2M专用频率层 /载^小区，根据所述配置就可以获知同频及邻频的 M2M专用小区列表，然后通过小区重选重新驻留到 M2M专用小区。 The information indicating the M2M dedicated cell in the current frequency point and the information indicating the M2M dedicated cell in the adjacent frequency point are added to the broadcast control message of the non-M2M dedicated frequency layer/carrier/cell. In this way, when the M2M terminal attempts to access the network according to the flow shown in FIG. 1, if a non-M2M dedicated frequency layer/carrier is searched, according to the configuration, a list of M2M dedicated cells of the same frequency and adjacent frequency can be obtained, and then Re-resident to the M2M dedicated cell by cell reselection.

一种可选的方式是在 SIB5中增加 MTC-InterFreqNeighCellList专用 MTC小区列表，用于指示相邻频点中专用于 M2M通信的专用小区；以及在 SIB4中增加用于指示当前频点中专用于 M2M通信的专用小区。具体如下所示： An optional manner is to add an MTC-InterFreqNeighCellList dedicated MTC cell list in SIB5 for indicating a dedicated cell dedicated to M2M communication in the adjacent frequency point; and adding in SIB4 to indicate that the current frequency point is dedicated to M2M.

The CI is a normal cell, that is, an H2H cell, and C2, C3, and C4 are M2M dedicated cells. Among them, C2 and CI have the same frequency, and C3, C4 and CI have different frequencies. The configuration of Cl, C2, C3, C4 is as follows:

在 C 1的广播控制消息中，在 SIB4中的 mtelntraFreqNeighCellList 中携带 C2的小区信息，在 SIB5的 mtc-interFreqNeighCellList中携带 C3、 C4的小区信息。在 C2、 C3、 C4的广播控制消息中，可以参考例 1或例 2的方式进行配置。 In the broadcast control message of C1, the cell information of C2 is carried in the mtelntraFreqNeighCellList in SIB4, and the cell information of C3 and C4 is carried in the mtc-interFreqNeighCellList of SIB5. In the broadcast control messages of C2, C3, and C4, you can refer to the method in Example 1 or Example 2.

The M2M terminal can perform cell reselection, and preferentially selects the best quality cell among the M2M dedicated cells C2, C3, and C4. If the quality of these several M2M dedicated cells does not satisfy the cell selection criteria, it still resides in the C1 cell.

当 M2M终端初始驻留在 C2或 C3或 C4上时，处理流程与例 2 相同，可以选择一个质量最优的小区进行驻留。 When the M2M terminal initially resides on C2 or C3 or C4, the processing flow is the same as in Example 2, and a cell with the best quality can be selected for camping.
