网络连接方法及装置Network connection method and device

技术领域Technical field

本发明涉及通信领域，具体而言，涉及一种网络连接方法及装置。The present invention relates to the field of communications, and in particular to a network connection method and apparatus.

背景技术Background technique

目前，网际协议第6版(Internet Protocol version 6，简称为IPv6)链路建立过程，分为状态化自动配置(即，有状态配置)和无状态地址自动配置(即，无状态配置)，具体哪种配置方式，是运营商分配的具体接入点名称(Access Point Name，简称为APN)决定的。其链路建立过程是，移动终端(mobile Terminal，简称为MT)(例如，数据卡)和网络侧协商一个唯一的接口标识(3G通过分组数据协议(Packet Data Protocol，简称为PDP)上下文激活，长期演进(Long-Term Evolution，简称为LTE)通过附着ATTACH的过程)，终端设备(Terminal Equipment，简称为TE，也可称为主机设备)通过和MT交互以获取这个接口标识；然后TE构建本地链路地址和网络侧进行路由请求(Router Solicitation，简称为RS)/路由通告(Router Advertisement，简称为RA)交互；TE通过RA中携带的信息，可确定是用状态化配置方式还是无状态配置方式。如果是状态化配置，TE和网络将会通过动态主机配置协议(Dynamic Host Configuration Protocol)DHCPv6交互，以获取IPv6地址和DNS等信息，建链完成；如果是无状态配置，则RA中携带有IPv6地址前缀，TE获取该IPv6地址前缀后，可以将该IPv6地址前缀和已经获取的接口标识组成全局IPv6地址，而域名服务器(Domain Name Server，简称为DNS)地址等信息则通过DHCPv6交互来获取。由此可知，无论是哪种方式，TE在每次建立链路时，都需要TE主机和网络之间直接交互数据才能完成。Currently, the Internet Protocol version 6 (IPv6) link establishment process is divided into stateful automatic configuration (ie, stateful configuration) and stateless address automatic configuration (ie, stateless configuration). Which configuration method is determined by the specific access point name (APN) assigned by the operator. The link establishment process is that a mobile terminal (MT) (for example, a data card) and the network side negotiate a unique interface identifier (3G is activated by a Packet Data Protocol (PDP) context). Long-Term Evolution (LTE) is a process of attaching an ATTACH. The terminal equipment (Terminal Equipment, also referred to as TE, also referred to as a host device) interacts with the MT to obtain the interface identifier. Then TE constructs the local device. The link address and the network side perform the routing request (Router Solicitation, RS for short) or the route advertisement (RA). The TE can determine whether to use the stateful configuration or the stateless configuration. the way. If it is a stateful configuration, the TE and the network will interact with the DHCPv6 through the Dynamic Host Configuration Protocol (DHCP) to obtain information such as the IPv6 address and the DNS. The link is completed. If the stateless configuration is configured, the RA carries the IPv6. After the IPv6 address prefix is obtained, the TE can obtain the IPv6 address prefix and the obtained interface identifier to form a global IPv6 address. The information such as the domain name server (DNS) address is obtained through DHCPv6 interaction. Therefore, in either case, the TE needs to directly exchange data between the TE host and the network to complete each time the link is established.

但是考虑应用于LTE网络下的物联网终端(即TE终端)，由于节约资源的考虑，常常会有某种策略，使得终端频繁联网断网。例如，在没有数据交互时，断开网络链接，在重新有数据要收发时，又建立链接。这种场景并不罕见，当前的数据类产品的“按需拨号”功能就是为了实现这个目的，另外，现在随处可见的快递员携带的刷卡POS机也是类似这种机制，刷卡前需要拨号，一段时间不用就自动断网。However, considering the application of an Internet of Things terminal (ie, a TE terminal) under the LTE network, due to resource conservation considerations, there is often a certain strategy that causes the terminal to frequently disconnect from the network. For example, when there is no data interaction, the network link is disconnected, and when there is data to be sent and received, a link is established. This kind of scenario is not uncommon. The “on-demand dialing” function of the current data products is to achieve this goal. In addition, the POS card POS machine carried by the courier can be seen everywhere, and it needs to be dialed before swiping. Automatically disconnects the network when time is not used.

针对物联网的第三代合作项目组织(The 3rd Generation Partnership Project，简称为3GPP)标准是长期演进-机器到机器(LTE-Machine to Machine，简称为LTE-M)，有LTE的大部分特点。当终端配合分组核心演进(Evolved Packet Core，简称为EPC)网络(即LTE***)工作时，由于LTE网络“永远在线”的特点，TE在开机后附着网络时就已经激活默认分组数据网(Packet Data Network，简称为PDN)，如果TE发起联网断网，实际只是TE和MT之间的交互，默认PDN连接是一直存在的。但是，在相关技术中，在TE每次联网后，MT都要和网络侧发生RS、RA交互，以获取IP、DNS地址信息。RS、RA信息是终端和核心网的交互，终端由于业务需要，发生断网、联网，联网过程中会有大量的RS/RA和DHCPv6消息，如果是在终端众多，信号覆盖较弱的物联网、传感器网络场景，一是消息数量将更大，二是信号覆盖较弱的区域常常存在收发数据前，无线链路建立失败需要重建的场景，这两种情形将会使得核心网网关负载更重。并且，对于TE来说，也会延长链路建立过程的时间。The 3rd Generation Partnership Project (3GPP) standard for the Internet of Things is a long-term evolution-machine-to-machine (LTE-Machine to Machine) (LTE-M), which has most of the features of LTE. When the terminal works with the Evolved Packet Core (EPC) network (ie, the LTE system), the TE has activated the default packet data network (Packet) when the network is attached to the network after the LTE network is "always on". Data Network (referred to as PDN). If the TE initiates network disconnection, it is only the interaction between TE and MT. The default PDN connection is always there. However, in the related art, after each time the TE is connected to the network, the MT interacts with the RS on the network side to obtain IP and DNS address information. The RS and RA information is the interaction between the terminal and the core network. The terminal has a network disconnection and networking due to the business needs. There are a large number of RS/RA and DHCPv6 messages during the networking process. If there are many terminals, the IoT with weak signal coverage Sensor network scenario, one is that the number of messages will be larger, and the other is the signal The weaker coverage area often has a scenario where the wireless link setup fails and needs to be re-established before sending and receiving data. These two scenarios will make the core network gateway load heavier. Also, for TE, it also lengthens the link setup process.

由此可知，在相关技术中，当TE发生多次断网后的联网操作时，需要与网络进行多次交互，从而造成网络侧负载重，TE侧联网时间长的问题。Therefore, in the related art, when the TE is connected to the network after multiple times of network disconnection, multiple interactions with the network are required, resulting in heavy load on the network side and long networking time on the TE side.

针对上述问题，相关技术中并未提出有效的解决方案。In view of the above problems, an effective solution has not been proposed in the related art.

具体实施方式detailed description

下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

随着物联网项目的启动，以及物联网本身技术的特点，IPv6应用更广。目前，相关技术中的IPv4配合NAT等协议还能活跃在市场上，而随着各种无线摄像头、家居自动化设备、可穿戴设备等机器类型通信(Machine Type Communications，简称为MTC)终端的大量涌现，IPv6的使用量逐步激增。相对于个人电脑(Personal Computer，简称为PC)等具有完善操作***的主机来说，MTC终端可能支持的协议栈并不完备，加上终端数目增速飞快，因此对于IPv6方面的技术，尤其是IPv6配合“瘦”主机的应用场景，相对于配合PC来说要求会苛刻，因此对现有机制的优化和完善，是非常重要的。下面对如何优化和完善现有机制进行说明：With the launch of the Internet of Things project and the characteristics of the Internet of Things itself, IPv6 is more widely used. At present, protocols such as IPv4 and NAT in related technologies can be active in the market, and a large number of machine type communication (Machine Type Communications, MTC for short) terminals emerge with various wireless cameras, home automation devices, and wearable devices. The use of IPv6 has gradually increased. Compared with a host computer with a complete operating system such as a personal computer (PC), the protocol stack that the MTC terminal may support is not complete, and the number of terminals increases rapidly, so the technology for IPv6, especially The application scenario of IPv6 with "thin" host is more demanding than the PC, so it is very important to optimize and improve the existing mechanism. Here's how to optimize and refine existing mechanisms:

在本实施例中提供了一种网络连接方法，图1是根据本发明实施例的网络连接方法的流程图，如图1所示，该流程包括如下步骤：A network connection method is provided in this embodiment. FIG. 1 is a flowchart of a network connection method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

步骤S102，移动终端MT获取网络分配的IPv6地址信息和域名服务器DNS信息；Step S102, the mobile terminal MT acquires IPv6 address information and domain name server DNS information allocated by the network;

步骤S104，当主机设备TE通过上述MT连接网络时，MT将上述IPv6地址信息和DNS信息发送给TE，其中，该IPv6地址信息和DNS信息用于TE接入上述网络。Step S104: When the host device TE connects to the network through the MT, the MT sends the IPv6 address information and the DNS information to the TE, where the IPv6 address information and the DNS information are used for the TE to access the network.

通过上述步骤，采用由移动终端MT将获取的网络分配的IPv6地址信息和域名服务器DNS信息发送给TE进行网络连接的操作，可以将网络侧的操作转移到MT上进行，从而在TE发生多次断网、联网操作时，由MT与TE进行联网信息的交互，避免TE与网络侧的频繁交互，从而减轻了网络侧压力，同时，由于MT和TE之间的交互速度比TE与网络侧交互速度快，可以大大节省TE的联网速度，从而解决了相关技术中存在的当TE发生多次断网后的联网操作时，需要与网络进行多次交互，从而造成网络侧负载重，TE侧联网时间长的问题，进而达到了降低网络侧负载，减少TE联网时间的效果。Through the above steps, the operation of transmitting the network-assigned IPv6 address information and the domain name server DNS information by the mobile terminal MT to the TE for network connection is performed, and the operation on the network side can be transferred to the MT, so that the TE occurs multiple times. When the network is disconnected or networked, the interaction between the network and the TE is performed, and the frequent interaction between the TE and the network is avoided, thereby reducing the pressure on the network side. At the same time, the interaction speed between the MT and the TE is higher than that between the TE and the network. The speed is fast, and the networking speed of the TE can be greatly saved, thereby solving the problem that the network has multiple interactions with the network when the network operation of the TE occurs after multiple network disconnection occurs in the related art, thereby causing heavy load on the network side and networking on the TE side. The problem of long time has reached the effect of reducing the network side load and reducing the TE networking time.

在一个可选的实施例中，在上述步骤S102中，MT获取网络分配的IPv6地址信息和DNS信息可以包括：MT在成功附着上述网络后，从本地空口协议栈中获取IPv6地址信息中的IPv6接口标识(例如，从网络返回的附着接收消息中获取IPv6地址信息中的IPv6接口标识)；以及，上述MT向网络发送第一路由请求RS消息，其中，该第一RS消息用于触发上述网络下发路由通告RA；上述MT根据网络下发的RA获取IPv6地址信息中的IPv6地址前缀和DNS信息。在本实施例中，MT可以首先向网络发起附着请求(Attach Request)，在附着成功后再执行上述步骤S102中的操作，相关的发起附着请求之后的操作可以参考现有技术。上述的IPn6接口信息和IPv6地址前缀可以拼接成完整的IPv6地址，并且，MT在获取上述的IPv6地址信息和DNS信息后，可以进行存储，从而使得当TE通过MT进行联网操作时，可以直接由MT将存储的IPv6地址信息和DNS信息发送给TE进行联网操作，避免TE与网络侧的交互。 In an optional embodiment, in step S102, the acquiring the IPv6 address information and the DNS information of the network by the MT may include: after the MT is successfully attached to the network, acquiring the IPv6 in the IPv6 address information from the local air interface protocol stack. The interface identifier (for example, the IPv6 interface identifier in the IPv6 address information is obtained from the attached receiving message returned by the network); and the MT sends a first routing request RS message to the network, where the first RS message is used to trigger the network. The route advertisement RA is delivered; the MT obtains the IPv6 address prefix and the DNS information in the IPv6 address information according to the RA delivered by the network. In this embodiment, the MT may first initiate an attach request to the network, and perform the operations in step S102 after the attach is successful. The related operations after the initiate attach request may refer to the prior art. The IPn6 interface information and the IPv6 address prefix can be spliced into a complete IPv6 address, and the MT can store the IPv6 address information and the DNS information, so that when the TE performs the networking operation through the MT, the TE can directly The MT sends the stored IPv6 address information and DNS information to the TE for network operation to avoid interaction between the TE and the network side.

TE operation. The specific transmission process can refer to the above embodiment.

下面结合具体实施例对本发明进行说明：The present invention will be described below in conjunction with specific embodiments:

在本发明实施例中，MT中主要包括三个模块，本地中继模块(Rm Relay)(对应于上述的发送模块24和处理模块72)和地址信息块(Address Information Block)模块和空口中继模块(Um Relay)(对应于上述的获取模块22)。其中，空口中继模块与网络侧(Network，简称为NW)进行交互。在MT附着网络时，空口中继模块和网络侧进行路由请求RS，路由通告RA以及DHCPv6通信；本地中继模块则在联网断网时和主机TE进行通信。图8是根据本发明实施例的***模块图，下面结合图8对***的整体架构进行说明：In the embodiment of the present invention, the MT mainly includes three modules, a local relay module (Rm Relay) (corresponding to the foregoing sending module 24 and processing module 72), an address information block module, and an air interface relay. Module (Um Relay) (corresponding to the acquisition module 22 described above). The air interface relay module interacts with the network side (Network, referred to as NW for short). When the MT attaches to the network, the air interface relay module and the network side perform routing request RS, route advertisement RA and DHCPv6 communication; and the local relay module communicates with the host TE when the network is disconnected. FIG. 8 is a system module diagram according to an embodiment of the present invention, and the overall architecture of the system is described below with reference to FIG. 8:

在图8中，82是TE，例如PC主机或物联网中的智能传感器；84是MT，它与网络侧和主机侧进行通信；86是本地中继模块(Rm Relay)，主要作用是和TE进行交互，如IPV6CP、RS/RA，以及DHCPv6消息的交互；88是地址信息块，会存储网络指定的IPv6地址前缀，IPv6接口标识，DNS地址等信息；810是空口中继模块(Um Relay)，地址信息块中的信息，需要由空口中继模块进行配置，空口中继模块和网络、本地空口协议栈进行交互，以获取IPv6地址信息。812是网络侧(NW)，如3GPP的LTE网络。In FIG. 8, 82 is a TE, such as a smart sensor in a PC host or the Internet of Things; 84 is an MT, which communicates with the network side and the host side; 86 is a local relay module (Rm Relay), and the main function is TE. Interacting, such as IPV6CP, RS/RA, and DHCPv6 message interaction; 88 is an address information block, which stores information such as IPv6 address prefix, IPv6 interface identifier, and DNS address specified by the network; 810 is an air interface relay module (Um Relay) The information in the address information block needs to be configured by the air interface relay module, and the air interface relay module interacts with the network and the local air interface protocol stack to obtain IPv6 address information. 812 is a network side (NW), such as an LTE network of 3GPP.

需要说明的是，空口中继模块和网络侧以及空口协议栈的交互是发生在附着ATTACH之后的。在ATTACH过程中默认的PDN已经建立，P-GW给终端分配的前缀等信息也已经到达了MT；MT通过网络下发的RA消息中的M-flag，O-flag可以确认具体的地址配置方法，如是无状态自动配置还是自动化状态配置，具体配置方法决定着后续本地中继模块和TE交互的流程。接着本地中继模块和TE的交互，该过程将发生于TE发起拨号(connect)时。且后续如果TE多次发起联网断网，TE仅和MT的本地中继模块交互，而无需再与网络交互，从而实现链路的快速建立。It should be noted that the interaction between the air interface relay module and the network side and the air interface protocol stack occurs after the ATTACH is attached. The default PDN has been established in the ATTACH process, and the information such as the prefix assigned by the P-GW to the terminal has also arrived at the MT. The M-flag and the O-flag in the RA message sent by the MT can confirm the specific address configuration method. If the stateless automatic configuration or the automatic state configuration, the specific configuration method determines the flow of the subsequent local relay module and TE interaction. Then the local relay module interacts with the TE, and the process will occur when the TE initiates a connect. And if the TE initiates the network disconnection multiple times, the TE only interacts with the local relay module of the MT, and does not need to interact with the network again, thereby achieving rapid establishment of the link.

本发明实施例中的终端能够使用IPv6链路和网络进行通信。对TE来说，能够加快链路的建立过程，对网络侧来说，能够显著减轻核心网网关的负载。“加快链路的建立过程”指的是在联网、断网的过程中，主机TE无须再和网络侧交互RS、RA等信息，有效的减少了P-GW网关负载，同时也减少了TE上IPv6和DNS地址等信息的配置时间。The terminal in the embodiment of the present invention can communicate with the network using an IPv6 link. For TE, the link establishment process can be accelerated, and the load on the core network gateway can be significantly reduced for the network side. “Accelerating the establishment process of the link” means that the host TE does not need to exchange RS, RA and other information with the network side during the networking and network disconnection, which effectively reduces the load of the P-GW gateway and reduces the TE. The configuration time of information such as IPv6 and DNS address.

下面结合上述各个模块对本发明进行整体简要说明：The present invention will be briefly described below in conjunction with the above various modules:

本发明的IPv6链路建立过程主要包括如下步骤：The IPv6 link establishment process of the present invention mainly includes the following steps:

第一步：在MT***客户识别模块(Subscriber Identity Module，简称为SIM)，开机激活时，发起国际移动用户标识符(International Mobile Subscriber Identifier，简称为IMSI)附着Attach过程；该过程完毕后，空口中继模块将和网络进行RS/RA，DHCPv6消息交互，获取网络分配的IPv6地址信息，配置到地址信息块中；空口中继模块也会从本地的空口协议栈中获取信息，如从PDN激活响应消息中携带的IPv6接口标识等，将其配置到地址信息块中； The first step is to insert a Subscriber Identity Module (SIM) in the MT. When the device is activated, the International Mobile Subscriber Identifier (IMSI) attaches the Attach process. After the process is completed, the process is completed. The port relay module will exchange RS/RA and DHCPv6 messages with the network to obtain the IPv6 address information assigned by the network and configure it into the address information block. The air interface relay module also obtains information from the local air interface protocol stack, such as from the PDN. The IPv6 interface identifier carried in the response message is configured into the address information block.

第二步：在TE发起拨号后，TE和MT进行LCP、IPV6CP交互，在IPV6CP交互过程中，MT从地址信息块中获取IPv6接口标识配置给TE；TE使用该接口标识生成本地链路地址；Step 2: After the TE initiates the dialing, the TE and the MT perform LCP and IPV6CP interaction. In the IPV6CP interaction process, the MT obtains the IPv6 interface identifier from the address information block and configures it to the TE; the TE uses the interface identifier to generate the local link address.

第三步：TE和MT之间进行RS/RA、DHCPv6交互，以获取全局单播IPv6地址和DNS等信息；此时TE已无需与网络进行RS/RA等数据包交换；Step 3: RS/RA and DHCPv6 interaction between the TE and the MT to obtain global unicast IPv6 address and DNS information; at this time, the TE does not need to exchange data packets such as RS/RA with the network;

第四步：如TE发起断网，仅断开TE和MT之间的PPP链路，而空口PDN仍是激活状态；Step 4: If the TE initiates a network disconnection, only the PPP link between the TE and the MT is disconnected, and the air interface PDN is still activated.

第五步：如TE重新发起联网，那么它在LCP、IPV6CP交互完成后，就会开始与网络尝试进行RS、RA，DHCPv6的交互，但是，实际上与之交互的是MT的本地中继模块，TE向网络侧发起的消息，终止于此模块，此模块对TE透明。正因为后续的重新联网过程不再发生实质上的终端、网络之间的交互，链路的建立变得快速，也节省了网络信令资源，减轻了网络负载。这正是本方案的意义所在。Step 5: If the TE re-initiates networking, then after the LCP and IPV6CP interaction is completed, it will start to interact with the network to perform RS, RA, and DHCPv6. However, the actual interaction module of the MT is actually interacting with it. The message initiated by the TE to the network side terminates in this module, and the module is transparent to the TE. It is precisely because the subsequent re-networking process no longer occurs between the terminal and the network, the establishment of the link becomes fast, the network signaling resources are saved, and the network load is reduced. This is what this program means.

步骤S902：MME给核心网网关发消息，请求建立默认承载；Step S902: The MME sends a message to the core network gateway to request to establish a default bearer.

步骤S903：P-GW通过DHCPv6机制，向外部的PDN的DHCP服务器请求IPv6地址等信息；Step S903: The P-GW requests information such as an IPv6 address from the DHCP server of the external PDN through the DHCPv6 mechanism.

步骤S904：创建会话响应，默认承载建立成功；Step S904: Create a session response, and the default bearer is successfully established.

步骤S905：Attach成功；Step S905: Attach succeeds;

步骤S906：空口中继模块主动向网络发送Router Solicitation(RS)消息，以触发网络立即下发Router Advertisement(RA)消息；Step S906: The air interface relay module sends a Router Solicitation (RS) message to the network to trigger the network to immediately send a Router Advertisement (RA) message.

步骤S907：空口中继模块接收到RA消息后，与网络侧进行DHCPv6交互(可能是状态化DHCPv6过程，也可能是无状态DHCPv6过程)。具体由RA消息中携带的参数M-flag、O-flag来确定。Step S907: After receiving the RA message, the air interface relay module performs DHCPv6 interaction with the network side (may be a stateful DHCPv6 process, and may also be a stateless DHCPv6 process). Specifically, it is determined by the parameters M-flag and O-flag carried in the RA message.

步骤S908：空口中继模块和网络侧之间进行DHCPv6过程。在无状态自动配置情况下，这里通常会获取到DNS服务器的地址，以及MTU等信息。在状态化自动配置的情况下，还可以获取到IPv6地址前缀。Step S908: The DHCPv6 process is performed between the air interface relay module and the network side. In the case of stateless autoconfiguration, the address of the DNS server and the MTU are usually obtained here. In the case of stateful autoconfiguration, an IPv6 address prefix can also be obtained.

步骤S909：TE发起联网请求。此后的过程是TE和MT间的过程。 Step S909: The TE initiates a networking request. The subsequent process is a process between TE and MT.

需要说明，在本实施例中，MT收到网络下发的RA消息中含有的内容，IPv6配置中继代理模块将按照原始内容记录下来，如其中的M-flag，O-flag，随后TE发起拨号时，仍将此原始RA发给TE。因为RA中含有该APN相关的地址配置方式的信息，这种方式是一种透明传输方式，在后续TE发起拨号时，它会认为是在同网络侧的P-GW进行信息交互。在完成了S908以上的步骤之后，TE就可以拨号发起建立IPv6链路了。It should be noted that, in this embodiment, the MT receives the content contained in the RA message sent by the network, and the IPv6 configuration relay agent module records the original content, such as M-flag, O-flag, and then TE initiates. This original RA is still sent to the TE when dialing. Because the RA contains the information about the APN-related address configuration mode, this mode is a transparent transmission mode. When the subsequent TE initiates dialing, it considers that it is performing information exchange with the P-GW on the network side. After completing the steps above S908, the TE can initiate an IPv6 link by dialing.

下面对MT与TE之间的交互进行说明：The following describes the interaction between MT and TE:

图10是根据本发明实施例的MT与TE的交互流程图，如图10所示，TE和MT之间的交互过程开始于TE发起拨号(connect)的时刻，即步骤S1001。S1002和S1003是PPP协商过程，分别是LCP协商(对应于步骤S1002)和IPV6CP协商(对应于步骤S1003)。在图10中，MT在Attach Accept消息中获取网络下发的IPv6接口标识并将其配置进地址信息块中；接口标识在步骤S1003中通过IPv6CP分配给TE，TE会用它来生成本地链路地址；步骤S1004和S1005是TE用本地链路地址进行的RS/RA过程(其中，RS过程对应于步骤S1004，RA过程对应于步骤S1005)，本地中继模块需要和地址信息模块通信，以获取地址配置方式的信息，以及地址信息。从TE的角度看，该过程是和核心网的交互过程，本案中，则被MT的中继代理模块透明的替换掉了。S1005的RA消息是复制了原始的P-GW发来的RA包，其中含有M-flag，O-flag，该RA中还可能携带有IPv6地址前缀。根据M和O的值，又分为两种常见情况，如果M和O都为1，S1006则应该发起DHCPv6请求，即TE通过DHCPv6过程获取包括IPv6，DNS地址在内的所有信息；如果M为0，O为1，S1005的RA中将会含有IPv6地址前缀，TE使用该IPv6地址前缀来生成全局IPv6地址；DNS地址则通过S1006的DHCPv6交互来获取。本地中继模块将采取RA消息中指定的配置方式，从地址信息块中获取信息，并和TE进行交互。FIG. 10 is a flowchart of interaction between an MT and a TE according to an embodiment of the present invention. As shown in FIG. 10, the interaction process between the TE and the MT starts at a time when the TE initiates a connection, that is, step S1001. S1002 and S1003 are PPP negotiation processes, which are LCP negotiation (corresponding to step S1002) and IPV6CP negotiation (corresponding to step S1003). In Figure 10, the MT obtains the IPv6 interface identifier sent by the network and configures it into the address information block in the Attach Accept message. The interface identifier is allocated to the TE through the IPv6CP in step S1003, and the TE uses it to generate the local link. Address; steps S1004 and S1005 are RS/RA procedures performed by the TE with a link-local address (wherein the RS process corresponds to step S1004, the RA process corresponds to step S1005), and the local relay module needs to communicate with the address information module to obtain Information about the address configuration method, as well as address information. From the perspective of TE, the process is an interaction process with the core network. In this case, it is transparently replaced by the relay agent module of the MT. The RA message of S1005 is that the RA packet sent by the original P-GW is copied, and the M-flag, O-flag is included, and the RA may also carry an IPv6 address prefix. According to the values of M and O, there are two common cases. If both M and O are 1, S1006 should initiate a DHCPv6 request. That is, the TE obtains all information including IPv6 and DNS addresses through the DHCPv6 process. If the O is 1, the S1005's RA will contain the IPv6 address prefix. The TE uses the IPv6 address prefix to generate the global IPv6 address. The DNS address is obtained through the DHCPv6 interaction of S1006. The local relay module will take the configuration specified in the RA message, obtain information from the address information block, and interact with the TE.

步骤S1007到S1009主要描述的是，在终端后续正常使用或待机过程中，TE发生一例断网(对应于步骤S1007)、联网(对应于步骤S1008)的情形，在S1009再次联网后，TE无需再与网络侧交互RS/RA等消息了，而是与MT进行RS/RA、DHCPv6的交互(对应于步骤S1009)从而实现了快速建链。Steps S1007 to S1009 mainly describe that in the subsequent normal use or standby process of the terminal, the TE has a case of disconnecting the network (corresponding to step S1007) and networking (corresponding to step S1008). After the network is reconnected in S1009, the TE does not need to be used again. The RS-RA and the like are exchanged with the network side, and the RS/RA and DHCPv6 are interacted with the MT (corresponding to step S1009) to realize rapid link establishment.

从图10可知，在本发明实施例中，透明的屏蔽了TE和网络侧的RS/RA、DHCPv6交互。在建链过程中，由于少了TE和网络的信息交互，一方面降低了网络侧网元的负载，另一方面加快了建链速度。As shown in FIG. 10, in the embodiment of the present invention, the RS and the RS/RA and DHCPv6 interactions on the network side are transparently shielded. In the process of building the chain, due to the lack of information exchange between the TE and the network, on the one hand, the load on the network side network element is reduced, and on the other hand, the link building speed is accelerated.

在本发明实施例中提出的方案是应用于IPv6链路建立方面的，是属于物联网最底层的感知层，是一种基础设施。具体的实际应用场景可以是在上层，底层可以为形形色色的上层应用提供服务，只要MTC设备需要独立IPv6地址，就需要联网，那么就可以应用本发明实施例中的方案进行优化。因此本发明实施例中的方案的实际应用场景是非常广的，如公共环境的智能公路摄像头阵列，居家安全方面的门锁、摄像头、运动检测器、火灾/烟雾/水灾/气体/入侵者报警器等，每个MTC设备作为TE，在联网后均分配有IPv6地址；在长期工作中有可能发生断网重连过程，那么重连时，就减少了RS/RA过程的交互，加快了建链速度，降低了P-GW的负载；The solution proposed in the embodiment of the present invention is applied to the IPv6 link establishment, and belongs to the lowest layer of the Internet of Things, and is an infrastructure. The specific application scenario may be in the upper layer, and the bottom layer may provide services for a variety of upper-layer applications. As long as the MTC device requires a separate IPv6 address, networking is required, and then the solution in the embodiment of the present invention may be applied for optimization. Therefore, the practical application scenarios of the solution in the embodiments of the present invention are very wide, such as an intelligent road camera array in a public environment, a door lock, a camera, a motion detector, a fire/smoke/flood/gas/intruder alarm in the home security aspect. Etc., each MTC device acts as a TE, and is assigned an IPv6 address after networking; The network reconnection process can occur, and when reconnecting, the interaction of the RS/RA process is reduced, the chain construction speed is accelerated, and the load of the P-GW is reduced;

另外需要说明的一点是，IPv6的概念提出了很多年，但当前并未全球广泛应用。原因在于当前物联网刚起步，还不太发达，目前的IPv4+NAT模式，还能满足基本需求。但是最近智能嵌入式设备，智能可穿戴设备数目爆发式发展，也只有IPv6能够满足物联网对于地质资源的海量性要求，实现“无所不在的IP”。近年来针对物联网和嵌入式网络，有很多IPv6的协议和技术规范出台，如用于支持IPv6和无线传感网的6LowPan等，这都说明在IPv6基础设施如链路配置方面的发明和优化，是紧急且重要的。Another point to note is that the concept of IPv6 has been proposed for many years, but it is not widely used globally. The reason is that the current Internet of Things has just started and is still not developed. The current IPv4+NAT model can also meet basic needs. However, the number of intelligent embedded devices and the number of smart wearable devices has recently exploded, and only IPv6 can meet the massive requirements of the Internet of Things for geological resources and achieve "ubiquitous IP." In recent years, there have been many IPv6 protocols and technical specifications for IoT and embedded networks, such as 6LowPan for supporting IPv6 and wireless sensor networks, which illustrate the invention and optimization of IPv6 infrastructure such as link configuration. It is urgent and important.
