领域本发明一般地涉及通信系统,更具体地说,涉及包括社区无线局域网(WLAN)的通信系统及使用同一系统的方法,所述社区WLAN用以在多个用户设备终端和公用网之间提供语音和数据通信。 FIELD The present invention relates generally to communication systems, and more particularly, to a method including community wireless LAN (WLAN) communication system and using the same system, the community for WLAN user equipment between a plurality of terminals and provide public network voice and data communications.

背景近年来,对通信网络及包括电话、寻呼机、传真机、计算机和网络接入设备等装置的使用呈指数级增长。 Background In recent years, the use of the communication network and comprises means phones, pagers, fax machines, computers and network access device such as exponentially. 在许多区域和社区,这种对语音和数据通信业务的增长的需求超过了支持这些业务所需的公共基础设施的增长。 In many regions and communities, the demand for voice and data traffic growth exceeded the growth needed to support these services public infrastructure.

上述问题的一个可能的解决方案是使用常规的公共或专用无线网络。 One possible solution to the above problem is to use conventional public or private wireless networks. 然而,由于许多原因,这种方式并不能完全令人满意。 However, due to many reasons, this approach is not entirely satisfactory. 使用常规无线网络的根本缺陷是能够与常规GSM(全球移动通信系统)、GPRS(通用分组无线业务)或3G(第三代蜂窝)无线网络通信的无线电或用户设备终端(UE)相关的成本。 Conventional wireless network is capable of fundamentally flawed, GPRS (General Packet Radio Service) or 3G (third generation cellular) costs associated with conventional GSM (Global System for Mobile Communications) radio or a user equipment terminal (UE) of a wireless communications network. 虽然这些UE的费用通常不由为社区提供语音和/或数据通信的无线网络服务提供商负担,但可以理解,成本越高则潜在的用户数量就会越少。 Although these costs UE is typically not provide voice and / or data communication for community wireless network service providers burden, it is understood that the higher the cost of the potential number of users will be less. 因此,服务提供商更不可能愿意承担在社区安装必需基站和交换中心的费用。 Thus, service providers can not be more willing to bear the cost of installing the necessary base stations and switching centers in the community.

现有无线网络所服务的区域或社区中的另一个问题是扩展网络以便为其他用户提供服务或提供其他服务的困难和费用。 Another problem area or community existing wireless network service is an extension of the network in order to provide services to other users or provide other services to the difficulty and expense. 例如,无线网络服务提供商用于提供增加容量的典型方法是安装额外的基站和交换中心。 For example, a typical wireless network service provider to provide a method to increase the capacity is to install additional base stations and switching centers. 如上所述,由于费用的原因,在某些农村或贫困地区和社区,这是不可接受的。 As mentioned above, for cost reasons, in certain rural or poor areas and communities, which is unacceptable. 另外,在许多发达地区和城市地区,这也是不可接受的,在那些地区,过度拥挤的许可频段因对重叠基站的干扰而导致附加基站和交换中心的容量减少。 Further, in many developed and urban areas, which is unacceptable, in those areas, because of overcrowding licensed bands overlap interference and the reduction of the capacity of the base station and additional switching center.

因此需要一种便宜的通信系统和操作同一系统的方法,其可以为常规通信系统至今尚未服务或在服务的社区用户提供语音和高速数据通信。 Therefore a need for an inexpensive communication system and method of operating the same system, which can be a conventional communication system or service has yet to provide voice and high-speed data communication services in the community of users. 还需要一种通信系统和操作同一系统的方法,其可以快速经济地加以扩展,以为不断增加的用户提供服务。 Also you need a communication system and method of operating the same system, which can be expanded quickly and economically, that increasing users. 另外,还需要一种通信系统和操作同一系统的方法,其可以为语音和数据通信提供大容量。 Further, a need for a communication system and method of operation of the same system, which can provide large capacity for voice and data communications.

现在将重复本发明的一些重要方面,以进一步强调其结构、功能和优点。 It will now be repeated a number of important aspects of the invention, to further emphasize its structure, functions and advantages.

可以理解,诸如IEEE 802.1X、HiperLAN/1或HiperLAN/2、HiperMAN和BRAN等WLAN标准可用于获得任何加密器所用的认证和加密密钥,并可用于定期刷新密钥和重新认证以确保密钥资料是最新的。 It will be appreciated, such as IEEE 802.1X, HiperLAN / 1 or HiperLAN / 2, HiperMAN BRAN and the like may be used to obtain any standard WLAN authentication and encryption key is used, and can be used to refresh the keys periodically to ensure that the re-authentication and key data is current. 这些标准并未规定一种认证方法;相反,它们利用可扩展认证协议(EAP)作为其认证框架。 The standard does not specify an authentication method; rather, they use the Extensible Authentication Protocol (EAP) as its authentication framework. 这使得启用WLAN的接入点228可支持多种认证方法,包括基于证书的认证、智能卡、令牌卡及一次性密码(one time and passwords)。 This makes WLAN-enabled access point 228 can support multiple authentication methods, including those based on certificates, smart cards, token cards and one-time password (one time and passwords). 或者,由于交换机和接入点228A、228B、228C充当EAP的传递口(pass-through),因此,通过在主机和后端认证服务器328上添加软件,可以添加新的认证方法而无需升级交换机或接入点。 Alternatively, since the switches and access points 228A, 228B, 228C serving as a delivery port EAP (pass-through), and therefore, by adding software on the host and the backend authentication server 328, authentication may be a method of adding a new switch, or without having to upgrade Access Point.

使用基于WLAN的认证方案的主要优点是将接入控制功能内置于每个接入点228A、228B、228C中。 The main advantage of using WLAN authentication scheme based on the access control function is built into each of the access points 228A, 228B, 228C in. 启用802.11的接入点228A、228B、228C可直接与RADIUS系统310或服务器312进行通信,以对用户或UE 230进行认证并生成会话的加密密钥。 802.11 enabled access point 228A, 228B, 228C may communicate directly with the RADIUS server 312 or system 310, a user or UE 230 to authenticate and generate encryption session keys. 接入点228A、228B、228C还可以存储用户的计费记录,并将它们传送到使用RADIUS计费协议的RADIUS系统310。 The access point 228A, 228B, 228C may also be stored in the user's billing records, and transmits them to the RADIUS accounting system 310 RADIUS protocol. 基于WLAN 228的方案可用于在有线LAN 229和业务提供商运营的WLAN 228中提供到因特网208的接入。 WLAN-based scheme WLAN 228 may be used to operate the wired LAN 229 and the service provider 228 provides access to the Internet 208. 而且,根据内置于诸如可从微软公司购得的WindowsXP操作系统等许多操作系统中的WLAN,通过使用WLAN 228的认证功能,可大大简化网络的客户机部分。 Further, according to a number of built-in operating system available from Microsoft Corporation, such as the operating system and the like WindowsXP WLAN, WLAN 228 by using the authentication function, the client can greatly simplify the network.
