Description
技术领域 technical field
本发明涉及通信技术领域，尤其涉及一种网络接入方法、业务处理方法、系统及设备。The present invention relates to the technical field of communication, and in particular to a network access method, a business processing method, a system and equipment.
背景技术 Background technique
随着通信技术的迅猛发展，无线运营商为用户提供多种无线接入网络，各种无线接入网络之间是完全独立的，例如：长期演进(Long Term Evolution，LTE)网络、第三代移动通信(3rd-Generation，3G)网络、无线局域网(WirelessLocal Area Network，WLAN)网络。With the rapid development of communication technology, wireless operators provide users with a variety of wireless access networks, which are completely independent, such as: Long Term Evolution (LTE) network, third-generation Mobile communication (3rd-Generation, 3G) network, wireless local area network (WirelessLocal Area Network, WLAN) network.
与此同时，终端设备上也设置了针对接入不同网络的多个接入模块，如图1所示的用户终端有3个接入模块，即为3G接入模块、LTE接入模块和WLAN接入模块，在不同应用场景下，终端设备用于可以根据需要，利用不同的接入模块接入相应的网络。At the same time, multiple access modules for accessing different networks are also set on the terminal equipment. As shown in Figure 1, the user terminal has three access modules, namely 3G access module, LTE access module and WLAN access module. The access module, in different application scenarios, the terminal device can use different access modules to access the corresponding network according to the needs.
例如：终端设备按照标准的802.1x接入WLAN的接入流程如图2所示，包括以下步骤：For example, the access process of a terminal device accessing a WLAN according to the standard 802.1x is shown in Figure 2, including the following steps:
步骤100：终端设备搜索WLAN信号，并将搜索到的WLAN服务集标识(Service Set Identifier，SSID)整理成列表。Step 100: The terminal device searches for WLAN signals, and organizes the searched WLAN Service Set Identifiers (Service Set Identifier, SSID) into a list.
步骤101：终端设备根据自身内存中配置的WLAN SSID和搜索到的WLAN SSID进行比较，如果两者匹配，则自动发起接入。Step 101: The terminal device compares the WLAN SSID configured in its own memory with the searched WLAN SSID, and automatically initiates access if the two match.
步骤102：终端设备主动发起扩展鉴权协议-用户标识模块/鉴权和密钥协商(Extensible Authentication Protocol-Subscriber Identity Module/Authenticationand Key Agreement，EAP-SIM/AKA)的认证，经由AC与3G网络中的认证、授权、计费(The 3rd Generation Partnership Project，Authentication，Authorization，Accounting，3GPPAAA)服务器交互，完成用户身份认证。Step 102: The terminal device actively initiates the authentication of the Extensible Authentication Protocol-Subscriber Identity Module/Authentication and Key Agreement (EAP-SIM/AKA), through the AC and the 3G network Authentication, authorization, accounting (The 3rd Generation Partnership Project, Authentication, Authorization, Accounting, 3GPPAAA) server interaction to complete user identity authentication.
步骤103：3GPPAAA从归属位置寄存器/归属用户服务器(Home LocationRegister/Home Subscriber Server，HLR/HSS)获取用户认证参数，完成与终端设备的EAP-SIM/AKA认证。Step 103: 3GPPAAA obtains user authentication parameters from Home Location Register/Home Subscriber Server (HLR/HSS), and completes EAP-SIM/AKA authentication with the terminal device.
步骤104：WLAN网络中的无线控制器/宽带接入服务器(AccessController/Broadband Remote Access Server，AC/BRAS)给用户分配本地IP地址。Step 104: The wireless controller/broadband access server (Access Controller/Broadband Remote Access Server, AC/BRAS) in the WLAN network assigns a local IP address to the user.
步骤105，终端设备根据获得的本地IP地址发起向域名服务器(DomainName Server，DNS)查询请求，DNS根据APN查询分组数据网关/增强型的分组数据网关(Packet Data Gateway/enhanced Packet Data Gateway，PDG/ePDG)的网关IP地址，并将查询结果返回给终端设备。Step 105, the terminal device initiates a domain name server (DomainName Server, DNS) query request according to the local IP address obtained, and the DNS queries the packet data gateway/enhanced packet data gateway (Packet Data Gateway/enhanced Packet Data Gateway, PDG/ ePDG) gateway IP address, and return the query result to the terminal device.
所述查询请求中携带了终端设备内存中配置的无线接入点(Access PointName，APN)。The query request carries the wireless access point (Access PointName, APN) configured in the memory of the terminal device.
步骤106：终端设备根据接收到的PDG/ePDG的网关IP地址向PDG/ePDG发起互联网密钥交换版本2(Internet Key Exchange version 2，IKEv2)的互联网协议安全性(Internet Protocol Security，IPsec隧道协商过程，建立从终端设备到PDG/ePDG的IPsec隧道。Step 106: The terminal device initiates the Internet Protocol Security (IPsec tunnel negotiation process) of Internet Key Exchange version 2 (Internet Key Exchange version 2, IKEv2) to the PDG/ePDG according to the received gateway IP address of the PDG/ePDG , to establish an IPsec tunnel from the terminal device to the PDG/ePDG.
步骤107：IPsec隧道建立后，PDG/ePDG为终端设备分配业务IP地址。Step 107: After the IPsec tunnel is established, the PDG/ePDG assigns a service IP address to the terminal device.
终端设备可以使用所述业务IP地址，承载用户的网络数据报文，而WLAN网络中的AC/BRAS给终端设备分配的本地IP地址作为IPsec的隧道传输地址。The terminal device can use the service IP address to bear the user's network data packets, and the local IP address assigned to the terminal device by the AC/BRAS in the WLAN network is used as the IPsec tunnel transmission address.
步骤108：终端设备完成接入WLAN网络流程，发起数据业务，将自身的业务流封装到IPsec隧道，并将业务流数据经由PDG/ePDG发送给无线接入网关。Step 108: The terminal device completes the process of accessing the WLAN network, initiates a data service, encapsulates its own service flow into an IPsec tunnel, and sends the service flow data to the wireless access gateway via the PDG/ePDG.
以上是以WLAN为例说明的终端设备接入WLAN的过程，针对3G接入模块接入3G网络的过程、以及LTE模块接入3G网络的过程，都可按照现有的3GPP标准进行接入。The process of terminal equipment accessing WLAN is described above using WLAN as an example. The process of 3G access module accessing 3G network and the process of LTE module accessing 3G network can be accessed according to the existing 3GPP standards.
然而，在现有的多种无线接入网络架构下，即使终端设备位于多种无线接入网络共同覆盖的区域，终端设备也只能按照上述WLAN、3G、LTE的方式选择其中一个无线网络接入，无法真正实现终端设备同时接入多个无线网络并使用多个无线网络的网络资源。However, under the existing multiple wireless access network architectures, even if the terminal device is located in an area covered by multiple wireless access networks, the terminal device can only select one of the wireless network access methods according to the above-mentioned WLAN, 3G, and LTE methods. However, it is impossible to realize that the terminal device can simultaneously access multiple wireless networks and use the network resources of multiple wireless networks.

实施例一Embodiment one
如图3所示，为本发明实施例一中网络接入的方法流程示意图，包括以下步骤：As shown in FIG. 3 , it is a schematic flowchart of a method for network access in Embodiment 1 of the present invention, including the following steps:
步骤201：终端设备向多个网络发送接入请求消息。Step 201: The terminal device sends access request messages to multiple networks.
由于终端设备具有接入各个网络所需的接入模块，因此在本步骤201中，终端设备可以向多个网络发送接入请求消息。Since the terminal device has access modules required for accessing various networks, in this step 201, the terminal device may send access request messages to multiple networks.
步骤202：终端设备确定其接入的其中一个网络所锚定的接入网关为自身分配的业务IP地址。Step 202: The terminal device determines the service IP address assigned to itself by the access gateway anchored by one of the networks it accesses.
在终端设备向网络发送接入请求消息后，接入网关将终端设备锚定在自身，并为终端设备分配在该网络中的业务IP地址，终端设备接收所述多个网络为其分配的业务IP地址，并确定其接入的其中一个网络所锚定的接入网关为自身分配的业务IP地址。After the terminal device sends an access request message to the network, the access gateway anchors the terminal device to itself, and allocates a service IP address in the network to the terminal device, and the terminal device receives the services allocated to it by the multiple networks IP address, and determine the service IP address allocated for itself by the access gateway anchored by one of the networks it accesses.
较优的，所述终端设备在并行接入多个网络时，确定接入的其中一个网络所锚定的接入网关具体为：Preferably, when the terminal device accesses multiple networks in parallel, it is determined that the access gateway anchored by one of the accessed networks is specifically:
终端设备在并行接入多个网络时，确定首次接入的无线网络所锚定的接入网关。When the terminal device accesses multiple networks in parallel, it determines the access gateway to which the wireless network accessed for the first time is anchored.
终端设备确定首次接入的无线网络所锚定的接入网关，此时，终端设备即可确定该接入网关为其分配的业务IP地址，进而能较快的成功接入其它网络。The terminal device determines the access gateway anchored by the wireless network that it accesses for the first time. At this time, the terminal device can determine the service IP address allocated by the access gateway, and then can quickly and successfully access other networks.
步骤203：终端设备在成功接入所述多个网络中的任一网络后，向接入网关发送IP地址请求信息，所述IP地址请求信息中携带了所述业务IP地址。Step 203: After successfully accessing any one of the plurality of networks, the terminal device sends IP address request information to the access gateway, and the IP address request information carries the service IP address.
步骤204：接入网关将所述业务IP地址作为该终端设备在当前成功接入的网络中所使用的IP地址。Step 204: The access gateway uses the service IP address as the IP address used by the terminal device in the network successfully accessed currently.
较优的，在所述首次接入的网络不为WLAN网络时，终端设备接入WLAN网络具体包括：Preferably, when the network accessed for the first time is not a WLAN network, the access of the terminal device to the WLAN network specifically includes:
接入网关为终端设备下发SSID；The access gateway issues the SSID for the terminal device;
终端设备将自身搜索到的SSID与接入网关下发的SSID进行比较，若匹配，则接入WLAN网络。The terminal device compares the SSID found by itself with the SSID issued by the access gateway, and if they match, it accesses the WLAN network.
终端设备利用上述网络接入方法，接入多个网络后，由于终端设备在不同的网络中具有相同的IP地址，因此，可以利用多个网络进行业务数据的传输。After the terminal device uses the above network access method to access multiple networks, since the terminal device has the same IP address in different networks, it can use multiple networks to transmit service data.
本发明实施例一的网络接入方法中，接入网关为同一终端设备在不同的网络分配相同的业务IP地址，使得终端设备可以向不同的网络同时发送业务数据，并接收来自不同网络发送的业务数据，因此，终端设备可以利用的网络带宽为多个网络带宽的和，加快了数据传输速度，改善了用户体验。In the network access method of Embodiment 1 of the present invention, the access gateway assigns the same service IP address to the same terminal device in different networks, so that the terminal device can simultaneously send service data to different networks and receive data from different networks. Service data, therefore, the network bandwidth that the terminal device can use is the sum of multiple network bandwidths, which speeds up the data transmission speed and improves the user experience.
在终端设备成功接入多个网络后，本发明实施例还提供一种业务处理方法，如图4所示，所述方法包括：After the terminal device successfully accesses multiple networks, the embodiment of the present invention also provides a service processing method, as shown in FIG. 4, the method includes:
步骤301：终端设备向网络侧发送业务分流策略请求信息。Step 301: The terminal device sends service distribution policy request information to the network side.
在本步骤301中，终端设备可以向其当前接入的网络中的任意一个网络发送业务分流策略请求信息，请求该网络为其下发业务分流策略。In this step 301, the terminal device may send service offloading policy request information to any one of the networks it is currently accessing, requesting the network to issue a service offloading policy for it.

步骤302：网络侧为终端设备确定分流策略，并向所述接入网关及终端设备发送该终端设备的分流策略。Step 302: The network side determines an offload policy for the terminal device, and sends the offload policy of the terminal device to the access gateway and the terminal device.
具体的，网络侧则根据终端设备发送的业务分流策略请求信息中携带的当前已接入的网络标识所对应的网络为该终端设备确定业务分流策略，该业务分流策略中包含了业务类型与承载网络的对应关系。Specifically, the network side determines the service distribution strategy for the terminal device according to the network corresponding to the currently accessed network identifier carried in the service distribution strategy request information sent by the terminal device. The service distribution strategy includes the service type and bearer network correspondence.
需要说明的是，本发明实施例中网络侧并不局限与根据终端设备当前接入的网络确定终端设备的业务分流策略，也可以结合网络当前的负荷，确定业务分流策略，例如：终端设备当前接入的网络为A网络和B网络，A类型的业务适合A网络传输，但当前A网络负荷较重，而B网络负荷较轻，则在确定业务分流策略时，可以将该A类型的业务承载在B网络。It should be noted that in this embodiment of the present invention, the network side is not limited to determining the service offloading strategy of the terminal device according to the network currently accessed by the terminal device, but can also determine the service offloading strategy based on the current load of the network, for example: The connected networks are A network and B network. Type A services are suitable for transmission on A network. However, the current load of A network is relatively heavy, while the load of B network is light. When determining the business distribution strategy, the A type of business can be It is carried on the B network.
总之，网络侧确定分流策略的总的原则是，将终端设备的业务数据分流到最合适的网络进行传输。In short, the general principle for determining the offload strategy on the network side is to offload the service data of the terminal device to the most suitable network for transmission.
步骤303：接入网关及终端设备接收并存储所述业务分流策略。Step 303: the access gateway and the terminal equipment receive and store the service distribution policy.
步骤304：终端设备根据接收的业务分流策略，确定承载当前业务的待发送信息的网络，并向确定的网络发送所述待发送的信息。Step 304: The terminal device determines the network carrying the information to be sent of the current service according to the received service offloading policy, and sends the information to be sent to the determined network.
较优的，终端设备根据接收的业务分流策略，确定承载待发送信息的网络，具体为：Preferably, the terminal device determines the network that bears the information to be sent according to the received service distribution strategy, specifically:
终端设备确定当前待发送消息的业务类型，根据业务分流策略中包含的业务类型与承载网络的对应关系，确定承载当前待发送信息的网络。The terminal device determines the service type of the message currently to be sent, and determines the network that bears the information currently to be sent according to the corresponding relationship between the service type included in the service distribution policy and the bearer network.
步骤305：在该终端设备的业务数据到达时，接入网关根据所述业务分流策略，确定承载所述业务数据的网络，并利用确定的网络发送所述业务数据。Step 305: When the service data of the terminal device arrives, the access gateway determines the network carrying the service data according to the service offloading policy, and uses the determined network to send the service data.
较优的，接入网关根据所述业务分流策略，确定承载所述业务数据的网络，具体为：Preferably, the access gateway determines the network carrying the service data according to the service offloading strategy, specifically:
接入网关确定所述业务数据的业务类型，根据所述业务分流策略中的业务类型与承载网络的对应关系，确定承载所述业务数据的网络。The access gateway determines the service type of the service data, and determines the network that bears the service data according to the correspondence between the service type and the bearer network in the service offloading policy.
需要说明的是，本步骤305中的业务数据包括终端设备的上行业务数据(从终端设备发送到网络侧的数据)和终端设备的下行业务数据(网络侧发送给终端设备的数据)。It should be noted that the service data in step 305 includes uplink service data of the terminal device (data sent from the terminal device to the network side) and downlink service data of the terminal device (data sent from the network side to the terminal device).
在步骤302中，网络侧将下发的业务分流策略发送给接入网关的目的是，当该终端设备的业务数据到达接入网关时，接入网关可以根据所述业务分流策略，确定承载所述业务数据的网络，并向确定的网络发送所述业务数据，也即本步骤305的方案，进而使得终端设备的业务数据在上行及下行均在最合适的网络上传输。In step 302, the purpose of the network side sending the issued service offloading policy to the access gateway is that when the service data of the terminal device arrives at the access gateway, the access gateway can determine the bearer traffic according to the service offloading policy The network of the above-mentioned service data, and send the above-mentioned service data to the determined network, that is, the solution of step 305, so that the service data of the terminal device is transmitted on the most suitable network in both uplink and downlink.

所述业务分流策略请求信息中携带了终端设备当前实际接入网络的网络标识。The service offload policy request information carries the network identifier of the terminal device currently actually accessing the network.
在本步骤第一步中，由于终端设备断开了其接入的其中一个或多个网络的连接，因此，原有的业务分流策略已不能使用，终端设备需重新确定业务分流策略。终端设备在向网络侧发送业务分流策略请求时，也可自行先调整业务分流策略，以便于在接收新的业务分流策略之前使用。In the first step of this step, since the terminal device is disconnected from one or more networks it accesses, the original service distribution strategy cannot be used, and the terminal device needs to re-determine the service distribution strategy. When the terminal device sends a service distribution strategy request to the network side, it can also adjust the service distribution strategy first, so as to use it before receiving a new service distribution strategy.
第二步：网络侧根据所述当前实际接入网络的网络标识，重新为终端设备下发业务分流策略。Step 2: The network side re-delivers the service distribution policy to the terminal device according to the network identifier of the current actually connected network.
第三步：接入网关接收及终端设备接收所述业务分流策略，并将本地存储的业务分流策略更新为本次接收的业务分流策略。Step 3: The access gateway receives the service distribution strategy and the terminal device receives the service distribution strategy, and updates the locally stored service distribution strategy to the service distribution strategy received this time.

实施例二Embodiment two
本发明实施例二将以终端设备同时接入3G/LTE、WLAN网络为例对实施例一中的网络接入的方法及业务处理方法进行详细说明。Embodiment 2 of the present invention will take a terminal device simultaneously accessing 3G/LTE and WLAN networks as an example to describe the network access method and service processing method in Embodiment 1 in detail.
在本发明实施例二中，由于终端设备接入同时接入的网络为无线网络，故在本发明实施例二中将本发明实施例一中的接入网关称为无线接入网关。In Embodiment 2 of the present invention, since the network that the terminal device accesses at the same time is a wireless network, the access gateway in Embodiment 1 of the present invention is referred to as a wireless access gateway in Embodiment 2 of the present invention.
如图5所示，为终端设备首次接入的网络为3G/LTE，并同时发起接入WLAN的流程示意图，包括以下步骤：As shown in Figure 5, the network that the terminal device accesses for the first time is 3G/LTE, and at the same time initiates a flow diagram of accessing the WLAN, including the following steps:
步骤400：终端设备发起3G/LTE接入流程，确定其在3G/LTE锚定的无线接入网关为其下发的业务IP地址。Step 400: The terminal device initiates a 3G/LTE access process, and determines the service IP address delivered to it by its wireless access gateway anchored in the 3G/LTE.
与此同时，搜索WLAN网络的SSID，并将搜索到的SSID整理成列表。At the same time, search for the SSID of the WLAN network, and organize the searched SSIDs into a list.
步骤401：无线接入网关为终端设备下发SSID。Step 401: The wireless access gateway issues an SSID to the terminal device.
在本步骤401中，无线接入网关主动为终端设备下发SSID，减少了用户对于网络接入的操作参与，优化了用户使用移动中终端的业务体验。In this step 401, the wireless access gateway actively issues the SSID for the terminal device, which reduces the user's participation in network access operations and optimizes the service experience of the user using the mobile terminal.
步骤402：终端设备将自身搜索到的SSID与无线接入网关下发的SSID进行比较，如果比较结果为匹配，则发起到WLAN的接入，并执行步骤403；如果比较结果为不匹配，则不发起WLAN的接入。Step 402: The terminal device compares the SSID it has searched for with the SSID sent by the wireless access gateway, if the comparison result is a match, then initiates access to the WLAN, and executes step 403; if the comparison result is no match, then WLAN access is not initiated.
步骤403：终端设备按照背景技术中步骤102-步骤108的流程接入WLAN网络。Step 403: The terminal device accesses the WLAN network according to the procedures of steps 102-108 in the background art.
步骤404：终端设备向所述无线接入网关发起IP地址请求，请求所述无线接入网关为其分配所述业务IP地址作为其在WLAN网络中所使用的IP地址。Step 404: The terminal device initiates an IP address request to the wireless access gateway, requesting the wireless access gateway to allocate the service IP address as the IP address used in the WLAN network.
具体的，终端设备通过(e)PDG向无线接入网关发起IP地址请求。Specifically, the terminal device initiates an IP address request to the wireless access gateway through the (e)PDG.
步骤405：无线接入网关为终端设备发送所述业务IP地址。Step 405: The wireless access gateway sends the service IP address for the terminal device.
经过上述步骤401-步骤405，终端设备同时接入了3G/LTE、WLAN，后续终端设备的业务数据由多个无线网络处理时，终端设备需要获知业务分流策略，以便于将不同的业务类型的业务数据通过不同的网络发送出去。如图6所示，为终端设备同时接入3G/LTE网络和WLAN网络后向网络获取分流策略的流程示意图，具体如下：After the above step 401-step 405, the terminal device is connected to 3G/LTE and WLAN at the same time, and when the service data of the subsequent terminal device is processed by multiple wireless networks, the terminal device needs to know the service distribution strategy, so as to facilitate the allocation of different service types Service data is sent through different networks. As shown in Figure 6, it is a schematic flow diagram of obtaining a distribution policy from the network after the terminal device simultaneously accesses the 3G/LTE network and the WLAN network, specifically as follows:
步骤501：终端设备接入到3G/LTE网络，访问数据业务。Step 501: The terminal device accesses the 3G/LTE network and accesses data services.
步骤502：终端设备获得3G/LTE网络分配的IP地址后，向网络侧发送业务分流策略请求信息，该业务分流策略请求信息中携带了3G/LTE的网络标识。Step 502: After obtaining the IP address assigned by the 3G/LTE network, the terminal device sends a service offload policy request message to the network side, and the service offload policy request message carries a 3G/LTE network identifier.
步骤503：终端设备接入WLAN网络。Step 503: The terminal device accesses the WLAN network.
步骤504：终端设备获得无线接入网关为其分配的所述业务IP地址后，向网络侧发送业务分流策略请求信息，该业务分流策略请求信息中携带了3G/LTE、WLAN网络的网络标识。Step 504: After obtaining the service IP address allocated by the wireless access gateway, the terminal device sends a service offload policy request message to the network side, and the service offload policy request message carries network identifiers of 3G/LTE and WLAN networks.
由上述步骤501-步骤504可知，终端设备在每次成功接入一个网络时，均可以向网络侧发送业务分流策略请求消息。终端设备接收网络侧针对步骤502中的业务分流策略请求而返回的业务分流策略，也接收到了网络侧针对步骤504中的业务分流策略请求而返回的业务分流策略，终端设备根据当前接入的网络，确定最终使用的业务分流策略，在本实施例中，终端确定最终使用的业务分流策略是网络侧针对步骤504中的业务分流策略请求而返回的业务分流策略，所述业务分流策略中包含了业务类型与承载网络的对应关系。It can be known from the above steps 501 to 504 that, each time the terminal device successfully accesses a network, it can send a service distribution policy request message to the network side. The terminal device receives the service distribution strategy returned by the network side for the service distribution strategy request in step 502, and also receives the service distribution strategy returned by the network side for the service distribution strategy request in step 504, and the terminal device according to the currently accessed network , to determine the final service distribution strategy to be used. In this embodiment, the terminal determines that the final service distribution strategy to be used is the service distribution strategy returned by the network side in response to the service distribution strategy request in step 504. The service distribution strategy includes Correspondence between service types and bearer networks.
一般的，业务分流策略可以为：服务质量(QoS)高的业务类型通过3G/LTE网络发送，例如语音业务；服务质量(QoS)低的业务类型通过WLAN网络发送，例如即时通信业务。Generally, the service offloading strategy may be: service types with high quality of service (QoS), such as voice services, are sent through the 3G/LTE network; service types with low quality of service (QoS), such as instant messaging services, are sent through the WLAN network.
网络侧为终端设备下发了业务分流策略，终端设备即可根据该业务分流策略进行业务数据的传输。如图7所示，为终端设备按照网络侧下发的业务分流策略进行业务处理的流程图，包括以下步骤：The network side issues a service distribution strategy to the terminal device, and the terminal device can transmit service data according to the service distribution strategy. As shown in Figure 7, it is a flow chart of the terminal device performing service processing according to the service offloading strategy issued by the network side, including the following steps:
步骤601：终端设备发起第一数据业务，确定所述第一数据业务的类型，根据网络侧下发的业务分流策略，确定承载所述第一数据业务为WLAN网络，将所述第一数据业务通过WLAN网络发送。Step 601: The terminal device initiates a first data service, determines the type of the first data service, determines that the WLAN network is the bearer of the first data service according to the service offload policy issued by the network side, and transfers the first data service to the WLAN network. Sent via Wi-Fi network.
步骤602：所述第一业务数据到达无线接入网关，无线接入网关根据本地储存的该终端设备的业务分流策略将所述第一业务数据发送到WLAN网络处理。Step 602: The first service data arrives at the wireless access gateway, and the wireless access gateway sends the first service data to the WLAN network for processing according to the locally stored service distribution policy of the terminal device.
步骤603：终端设备发起第二数据业务，确定所述第二数据业务的类型，根据网络侧下发的业务分流策略，确定承载所述第二数据业务为3G网络，将所述第二数据业务通过3G网络发送。Step 603: The terminal device initiates the second data service, determines the type of the second data service, determines that the second data service is carried by the 3G network according to the service offload policy issued by the network side, and transfers the second data service Sent via 3G network.
步骤604，所述第二业务数据到达无线接入网关，无线接入网关根据本地储存的该终端设备的业务分流策略将所述第二业务数据发送到3G网络处理。Step 604, the second service data arrives at the wireless access gateway, and the wireless access gateway sends the second service data to the 3G network for processing according to the locally stored service distribution policy of the terminal device.
由本实施例二的终端设备网络接入过程及业务处理过程可知，终端设备可以同时接入3G/LTE网络和WLAN网络，并根据业务分流策略将不同类型的业务数据发送至不同的网络进行处理，增加了用户数据业务带宽(用户数据业务带宽是其接入的各个网络的带宽之和)，优化了网络资源的使用，提高了数据传输速度，进而提升了用户体验。It can be seen from the terminal device network access process and service processing process in the second embodiment that the terminal device can simultaneously access the 3G/LTE network and the WLAN network, and send different types of service data to different networks for processing according to the service distribution strategy. The user data service bandwidth is increased (the user data service bandwidth is the sum of the bandwidths of the various networks it accesses), the use of network resources is optimized, the data transmission speed is improved, and the user experience is further improved.
假设终端设备同时接入的网络为WLAN和3G网络，在终端设备发生移动离开WLAN网络覆盖后，终端设备仍可保持数据业务连续，保持数据业务连续的流程示意图如图8所示，包括以下步骤：Assuming that the networks that the terminal device accesses at the same time are WLAN and 3G networks, after the terminal device moves away from the coverage of the WLAN network, the terminal device can still maintain the continuity of the data service. The schematic diagram of the process for maintaining the continuity of the data service is shown in Figure 8, including the following steps :
步骤701：终端设备发起第三业务数据，确定所述第三数据业务的类型，根据网络侧下发的业务分流策略，确定承载所述第三数据业务为WLAN网络。Step 701: The terminal device initiates third service data, determines the type of the third data service, and determines that the third data service is carried by a WLAN network according to a service offload policy issued by the network side.
步骤702：终端设备将所述第三数据业务通过WLAN网络发送至无线接入网关。Step 702: The terminal device sends the third data service to the wireless access gateway through the WLAN network.
步骤703：终端设备发生移动离开WLAN网络覆盖范围，终端设备检测到WLAN网络无线信号不可用。Step 703: The terminal device moves away from the coverage of the WLAN network, and the terminal device detects that the wireless signal of the WLAN network is unavailable.
步骤704：终端设备自动调整业务数据的发送路径，将所述第三数据业务通过3G网络进行发送，并通知网络侧进行业务分流策略的更新。Step 704: The terminal device automatically adjusts the sending path of the service data, sends the third data service through the 3G network, and notifies the network side to update the service distribution strategy.
在上述步骤704中，由于终端设备可用的网络只剩下一个，即3G网络，此时，终端设备不再向网络侧请求业务分流策略，但通知网络侧更新业务分流策略，以便于网络侧能正确的处理终端设备的业务数据。In the above step 704, since there is only one network available to the terminal device, that is, the 3G network, at this time, the terminal device no longer requests the service distribution strategy from the network side, but notifies the network side to update the service distribution strategy, so that the network side can Correctly process business data of terminal equipment.
若在上述步骤704中，终端设备仍然有两个可用的网络时，终端设备将向网络侧重新发送业务分流策略请求信息，根据本次接收到的业务分流策略，发送业务数据，保证用户的业务始终保持连续。If in the above step 704, the terminal device still has two available networks, the terminal device will resend the service distribution strategy request information to the network side, and send service data according to the service distribution strategy received this time to ensure the user's service Always be continuous.
综上所述，终端设备只要与一个网络保持连接，即可保证数据业务传输的不中断，用户的体验不受影响。To sum up, as long as the terminal device is connected to a network, it can ensure uninterrupted data service transmission and user experience will not be affected.
同样的，当终端设备新接入一个网络时，则此时将向网络侧重新发送业务分流策略请求信息，根据本次接收到的业务分流策略，发送业务数据，保证业务数据通过当前接入的网络中最合适的网络发送。Similarly, when a terminal device is newly connected to a network, it will resend the service distribution policy request information to the network side at this time, and send service data according to the service distribution policy received this time to ensure that the service data passes through the currently connected The most suitable network send in the network.
