This phenomenon reflects the sharp rise in people's demand for mobility and information. Therefore, the trend of combining mobile with the Internet is a historical necessity, and the mobile Internet is gradually penetrating into all areas of people's life and work.
为了使用户通过移动通信网访问互联网，运营商对现有的移动通信网的基础架构做了多次升级和业务扩展，例如：网关GPRS支持节点GGSN和GPRS服务支持节点SGSN，GGSN可以和多种不同的数据网络连接，如ISDN、PSPDN和LAN等，GGSN可以把GSM网中的GPRS分组数据包进行协议转换，从而可以把这些分组数据包传送到远端的TCP/IP或X.25网络，GGSN具有PDP上下文激活、PDP上下文修改、PDP上下文去激活的功能；GGSN具有地址翻译和映射功能,包括查找DNS,实现域名解析功能，GGSN具有封装和隧道传输功能,可以将来自外部数据网的PDP PDU用GTP字头和TCP/IP或UDP/IP字头进行分装的功能,并以这些字头中的恶相关地址信息作为标识；SGSN主要完成分组数据包的路由转发、移动性管理、会话管理、逻辑链路管理、鉴权和加密、话单产生和输出等功能。In order to allow users to access the Internet through the mobile communication network, operators have upgraded the infrastructure of the existing mobile communication network and expanded services several times, for example: gateway GPRS support node GGSN and GPRS service support node SGSN, GGSN can communicate with various Different data network connections, such as ISDN, PSPDN and LAN, etc., GGSN can convert the GPRS packet data packets in the GSM network, so that these packet data packets can be transmitted to the remote TCP/IP or X.25 network, GGSN has the functions of PDP context activation, PDP context modification, and PDP context deactivation; GGSN has address translation and mapping functions, including DNS lookup, and domain name resolution functions. The PDU uses the GTP header and the TCP/IP or UDP/IP header to carry out the subpackage function, and uses the evil-related address information in these headers as an identification; SGSN mainly completes the routing and forwarding of packet data packets, mobility management, and session Management, logical link management, authentication and encryption, bill generation and output and other functions.
然而，现有的移动通信网中的网络设备的负载量是有限的，对于运营商而言，必须重新调整他们的网络接入策略，以适应日益增长的移动设备上网需求，具体包括：更高数据吞吐量，并且低时延；更低的建设和运行维护成本；与现有网络的可兼容性。因此，亟需一种针对上述需求的移动互联网访问系统。However, the load of network equipment in the existing mobile communication network is limited. For operators, they must readjust their network access strategies to meet the growing demand for mobile devices to access the Internet, including: higher Data throughput and low latency; lower construction and operation and maintenance costs; compatibility with existing networks. Therefore, there is an urgent need for a mobile Internet access system aimed at the above-mentioned requirements.

图2为应用图1所示的移动互联网访问系统进行的移动互联网访问方法流程图，结合图2所示的方法，具体说明通过图1所示的移动互联网访问系统各个设备是如何工作完成移动互联网访问的，如图2所示，该方法包括：Fig. 2 is a flowchart of a mobile Internet access method using the mobile Internet access system shown in Fig. 1. In combination with the method shown in Fig. 2, it is specifically explained how each device of the mobile Internet access system shown in Fig. 1 works to complete the mobile Internet Accessed, as shown in Figure 2, the method includes:
步骤100，第一基站对归属于自身的移动台发送的、用于进行互联网访问的数据包，采用自身具有的网内协议地址进行封装处理，并根据与自身对应的路由信息将封装处理后的数据包通过至少一个数据传输节点发送给部署在核心网中、且与网关相连接的第一数据传输节点；Step 100, the first base station encapsulates the data packet sent by the mobile station belonging to itself and used for Internet access, using its own network protocol address, and encapsulates the packet according to the routing information corresponding to itself The data packet is sent to the first data transmission node deployed in the core network and connected to the gateway through at least one data transmission node;
当移动台需要进行互联网访问时，向自身所归属的第一基站发送用于进行互联网访问的数据包，从而第一基站接收归属于自身的移动台发送的、用于进行互联网访问的数据包。需要说明的是，第一基站可以通过具体的业务类型标识或者要访问的目的地址信息来判断该数据包是用于进行互联网访问的。第一基站需要将该数据包通过接入网发送至核心网，以使核心网通过与互联网之间的网关将数据包发送至互联网，但是，与现有技术相比，第一基站不再通过现有的移动通信网设备比如网关GPRS支持节点GGSN和GPRS服务支持节点SGSN将用于进行互联网访问的数据包发送到核心网，因为这些设备在满足传统的移动通信业务之外，还要负荷海量的互联网数据业务，导致设备资源紧张，处理效率较低。When the mobile station needs to access the Internet, it sends a data packet for Internet access to the first base station to which it belongs, so that the first base station receives the data packet for Internet access sent by its own mobile station. It should be noted that the first base station may determine that the data packet is used for Internet access based on the specific service type identifier or destination address information to be accessed. The first base station needs to send the data packet to the core network through the access network, so that the core network can send the data packet to the Internet through the gateway between the Internet, but, compared with the prior art, the first base station no longer passes Existing mobile communication network devices such as gateway GPRS support node GGSN and GPRS service support node SGSN send data packets for Internet access to the core network, because these devices must also load massive Internet data services, resulting in tight device resources and low processing efficiency.
本实施例在接入网和/或核心网中部署了多个数据传输节点，需要注意的是，部署在核心网中与网关相连接的数据传输节点为第一数据传输节点，第一数据传输节点为一个或者多个，每个第一基站根据预先部署的路由信息通过至少一个数据传输节点与核心网上的第一数据传输节点连接，其中，每个第一基站和每个数据传输节点都具有符合移动通信网设备互联协议、用于移动通信网设备之间相互传递信息的网内协议地址，即意味着第一基站和数据传输节点之间可以使用网内协议地址基于预先部署的路由信息进行信息传递。需要注意的是，网内协议地址不同于移动台进行互联网访问所用的IP地址，移动台发送的用于进行互联网访问的数据包包括自身的IP地址和待访问的互联网内的目标设备的目标IP地址，各个移动台发起互联网访问所用的IP地址和互联网内的节点所拥有的IP地址是符合TCP/IP协议的地址信息，与本实施例中接入网中的第一基站和接入网和/或核心网中部署的多个数据传输节点所具有的符合移动通信网设备互联协议、用于移动通信网设备之间相互传递信息的网内协议地址不同，网内协议地址由本领域技术人员根据系统规模和所部属的数据传输节点的数量和层次进行分配，因此，多个数据传输节点不能识别IP地址。因此，第一基站需要采用自身具有的网内协议地址对归属于自身的移动台发送的、用于进行互联网访问的数据包进行封装处理，并根据与自身对应的路由信息将封装处理后的数据包发到对应的数据传输节点，从而通过至少一个数据传输节点发送到部署在核心网上，且与网关相连接的第一数据传输节点。举例说明如下：移动台A要访问互联网中的B设备，移动台A将包含自身的IP地址192.0.0.1和互联网中的B设备的IP地址192.0.1.3的报文发送给所归属的第一基站，第一基站用自身具有的网内协议地址10.0.0.2进行封装处理，以根据预先部署的与自身对应的路由信息将封装处理后的数据包发送给对应的数据传输节点，数据传输节点所具有的网内协议地址都属于10.0.0.X地址体系，从而通过路由寻址将该数据包发送给该路由信息指定的第一数据传输节点。In this embodiment, multiple data transmission nodes are deployed in the access network and/or core network. It should be noted that the data transmission node deployed in the core network and connected to the gateway is the first data transmission node, and the first data transmission node There are one or more nodes, and each first base station is connected to the first data transmission node on the core network through at least one data transmission node according to pre-deployed routing information, wherein each first base station and each data transmission node have Compliant with the mobile communication network device interconnection protocol, the intra-network protocol address used to transmit information between mobile communication network devices means that the first base station and the data transmission node can use the intra-network protocol address based on pre-deployed routing information. Information transfer. It should be noted that the intranet protocol address is different from the IP address used by the mobile station to access the Internet. The data packet sent by the mobile station for Internet access includes its own IP address and the target IP address of the target device in the Internet to be accessed. Address, the IP address used by each mobile station to initiate Internet access and the IP address owned by the nodes in the Internet are address information that conforms to the TCP/IP protocol, and is related to the first base station and the access network in the access network in this embodiment. /or the multiple data transmission nodes deployed in the core network have different intra-network protocol addresses that conform to the mobile communication network device interconnection protocol and are used to transfer information between mobile communication network devices. The intra-network protocol addresses are determined by those skilled in the art according to The system scale and the number and level of the deployed data transmission nodes are allocated, therefore, multiple data transmission nodes cannot identify IP addresses. Therefore, the first base station needs to use its own network protocol address to encapsulate the data packets sent by its own mobile station for Internet access, and according to the routing information corresponding to itself, the encapsulated data packets The packet is sent to the corresponding data transmission node, so as to be sent to the first data transmission node deployed on the core network and connected to the gateway through at least one data transmission node. An example is as follows: mobile station A wants to access device B in the Internet, mobile station A sends a message containing its own IP address 192.0.0.1 and the IP address of device B in the Internet 192.0.1.3 to the first base station to which it belongs , the first base station uses its own network protocol address 10.0.0.2 to perform encapsulation processing, so as to send the encapsulated data packet to the corresponding data transmission node according to the pre-deployed routing information corresponding to itself, and the data transmission node has All intranet protocol addresses belong to the 10.0.0.X address system, so that the data packet is sent to the first data transmission node specified by the routing information through routing addressing.
需要说明的是，数据传输节点用于完成数据的转发和传递，比如可以包括：路由器和/或交换机，就路由器与交换机来说，交换机工作在数据链路层，路由器工作在网络层，交换机是利用物理地址或者说MAC地址来确定转发数据的目的地址，而路由器则是利用不同网络协议号来确定数据转发的地址，本领域技术人员可以根据具体的应用场景的规模和需要进行配置。与现有工作的移动通信网设备比如GGSN和SGSN，大量的数据传输节点建设和运行维护成本非常低，并且通过网内协议地址可以和现有的基站兼容工作。It should be noted that the data transmission node is used to complete the forwarding and delivery of data, for example, it may include: a router and/or a switch. As far as the router and the switch are concerned, the switch works at the data link layer, the router works at the network layer, and the switch is The physical address or MAC address is used to determine the destination address of forwarded data, while the router uses different network protocol numbers to determine the address of data forwarded. Those skilled in the art can configure according to the scale and needs of specific application scenarios. Compared with the existing mobile communication network equipment such as GGSN and SGSN, the cost of construction, operation and maintenance of a large number of data transmission nodes is very low, and it can work compatible with existing base stations through the intranet protocol address.
需要说明的是，每个第一基站和每个数据传输节点所具有的网内协议地址，以及与每个第一基站对应的、从第一基站经过多个数据传输节点到核心网的路由信息可以是移动管理实体所分配和部署的。另外，移动台发送互联网访问业务所用的IP地址可以是第一基站通过核心网从互联网获取动态主机配置协议服务器分配的、与第一基站的标识信息对应的IP地址池，以根据IP地址池为归属于自身且进行互联网访问的移动台分配的IP地址。It should be noted that each first base station and each data transmission node have an intra-network protocol address, and corresponding to each first base station, routing information from the first base station to the core network via multiple data transmission nodes It may be allocated and deployed by the mobility management entity. In addition, the IP address used by the mobile station to send the Internet access service may be the IP address pool allocated by the dynamic host configuration protocol server obtained by the first base station from the Internet through the core network and corresponding to the identification information of the first base station. An IP address assigned by a mobile station that belongs to itself and that accesses the Internet.
步骤101，第一数据传输节点对采用网内协议地址标识的数据包进行解封装处理，并通过所述网关发送给所述互联网。Step 101, the first data transmission node decapsulates the data packet identified by the intranet protocol address, and sends it to the Internet through the gateway.
第一数据传输节点通过至少一个数据传输节点接收第一基站发送的用于互联网访问的数据包后，对采用网内协议地址标识的数据包进行解封装处理，以使并将处理后的数据包通过网关发送给互联网。After the first data transmission node receives the data packet for Internet access sent by the first base station through at least one data transmission node, it decapsulates the data packet identified by the intranet protocol address, so that the processed data packet sent to the Internet through the gateway.
