一种复合式无线网络交联方法 A composite radio network crosslinking process

技术领域 FIELD

[0001] 本发明涉及一种用于支持网络终端设备(WLAN UE)连接网络的技术,尤其涉及一种用于支持无线局域网络(WLAN)与移动数据网络交互的技术。 [0001] The present invention relates to a connection network support network terminal equipment (WLAN UE) is used, and in particular relates to a technique for supporting a wireless local area network (WLAN) mobile data network interaction.

背景技术 Background technique

[0002] 随着通信技术的发展,人们对网络终端设备的使用越来越多,网络终端设备连接网络的技术也在日益更新,其发展速度不断加快。 [0002] With the development of communication technology, people use more and more network terminal equipment, network terminal equipment connected to the network technology is also increasingly update, its growth rate is accelerating. 目前,比较普遍的用于网络终端设备连接网络的技术是第三代合作伙伴计划(3rd Generation Partnership Project, 3GPP)提出的通过无线局域网络(WLAN)经移动网络鉴权后可接入至移动分组域的技术。 Currently, more generally, a network terminal device connected to the network technology is the third generation partnership project (3rd Generation Partnership Project, 3GPP) may be made after the mobile access to the mobile network authentication packet through a wireless local area network (WLAN) technology domain. 在该技术中,3GPP定义了两种流程:流程一是用户通过WLAN接入,移动网络鉴权后,可直接接入至互联网;流程二是用户通过WLAN接入,移动网络鉴权后,接入至移动分组域,并经过移动分组域访问运营商网络、企业网或者互联网。 In this technology, 3GPP has defined two processes: First, the user process through WLAN access, the mobile network authentication, can directly access to the Internet; the second is the user process through WLAN access, the mobile network authentication, then to move into the packet domain, and domain access through mobile packet network operators, enterprise network or the Internet.

[0003] 这两种流程被采用为当前主流的技术,于是当用户使用网络终端设备连接网络时的技术步骤基本上为: [0003] Both processes are employed for the current mainstream technology, so when the user steps using techniques network terminal device connected to the network is substantially:

[0004] 1.用户进行终端数据配置选择采用上述两种流程之一。 [0004] 1. The user terminal configured to select data in one of the two processes.

[0005] 2.网络终端设备扫描可用WLAN的服务识别码(SSID),并由用户从中选择出最优的WLAN。 [0005] 2. The network terminating device scans for available WLAN service identifier (SSID), selected by the user from an optimal WLAN.

[0006] 3.网络终端设备通过WLAN接入,申请进行移动网络鉴权,鉴权通过后,进入WLAN附着态。 [0006] 3. The network terminal device through the WLAN access network authentication request to move, after the authentication is passed, to enter the WLAN attached state.

[0007] 4.用户进行互联网业务访问请求,如终端数据配置为流程一,则通过WLAN直接访问互联网;如终端数据配置为流程二,则通过WLAN,至分组数据网关(PDG)建立通道,进入WLAN连接态,用户经WLAN及移动分组域访问互联网。 [0007] 4. The user of Internet service access request, such as a terminal for the process data configuration, direct access to the Internet through the WLAN; The terminal is configured to process two data, via the WLAN, to a packet data gateway (the PDG) establishes the tunnel, into the WLAN connection state, the user via the WLAN to access the Internet and mobile packet domain.

[0008] 5.用户在访问业务过程中如修改终端数据配置,网络终端设备至分组数据网关(PDG)所建立的通道将被断开,并根据数据配置选择重新建立。 [0008] 5. The user access to modify the course of business terminal configuration data, the network terminal device to the gateway packet data channel (the PDG) established will be disconnected and re-established in accordance with the configuration data selection.

[0009] 然而,从运营商角度看,引入WLAN接入移动分组域,主要目的就是利用WLAN作为移动网络的有效的补充,缓解移动网络的压力,充分均衡利用移动网络和WLAN的资源,提供更好的网络服务。 [0009] However, from the operator's point of view, the introduction of WLAN access mobile packet domain, the main purpose is to use the WLAN as an effective complement to the mobile network, the mobile network to ease the pressure, full and balanced use of resources of the mobile network WLAN, providing more good network services. 3GPP虽然定义了两种教完善的流程,允许用户经WLAN接入,移动网络鉴权后,可直接接入互联网或者经移动分组域接入运营商网络、企业网或者互联网。 Although 3GPP defines two perfect teaching process, allowing the user after WLAN access, mobile network authentication, direct access to the Internet or through mobile packet domain access network operators, enterprise network or the Internet. 两种流程均允许用户访问互联网等外部网络,但3GPP并未明确提出什么场景下该应用哪种流程,当两种流程均可应用时该如何选择使用也成为问题。 Two kinds of processes are allowing users to access the Internet and other external networks, but 3GPP has not made it clear what the application process under what scenario, how the process can be applied when both the select use has become a problem. 用户只能通过手动方式在网络终端设备的配置工作上进行网络选择,然后再通过人工体验选择较优的网络为自己服务。 The user can select the network configuration work in the network terminal equipment manually, and then manually select superior network experience for their own services.

发明内容 SUMMARY
