技术领域 FIELD

本发明涉及无线局域网(WLAN)和广域移动无线网之间的网际互联。 The present invention relates to the internetworking between a wireless LAN (WLAN) and wide-area mobile radio network.

背景技术 Background technique

采用无线技术的用户日益以较大的数目增长。 Users are increasingly using wireless technology to grow at a greater number. 由于极具吸引力的速率计划,更加刺激了这种趋向,此计划将电话费用带到社会中大多数人都可以接受的水平。 Due to attractive rate plans, more to stimulate this trend, this plan will call costs to the society, most people acceptable level. 用户的电话需要几乎完全依赖移动电话的现象更加普遍。 Users need to rely almost exclusively on phone mobile phone phenomenon is more common. 然而,在办公室或公司环境中,移动电话因为若干原因不能胜过有线线路的公司电话,在这些原因中突出的原因如下:·在办公大楼内来自广域网络基础结构的弱R/F信号,导致移动管理和话音质量的问题。 However, in an office or corporate environment, the mobile phone can not be overcome for several reasons wireline telephone company, projecting in these reasons the following reasons: * Weak R / F signal from the wide area network infrastructure in the office building, resulting in mobility management and voice quality problems.

·办公室电话系统内专用PBX特征的可用性,例如缩位拨号,提供持续使用公司电话方案的强烈诱因。 · Within a dedicated PBX office phone systems feature availability, such as abbreviated dialing, providing a strong incentive for continued use of company cell phone plan.

目前的情形是,人们使用两种不同的电话系统,一种在无线广域网中,另一种在公司场地中,其是有线线路电话系统,导致了多个手机、语音信箱和寻址机构。 The current situation is that people use two different phone systems in a wireless wide area network, another company in the field, it is a wireline telephone system, resulting in a number of cell phones, voice mail, and addressing mechanism.

和这些发展相平行,无线局域网络越来越广泛用于无线数据应用。 And parallel to these developments, wireless local area network is widely used for wireless data applications. 在这种网络中,合理带宽可用于公司无线客户,例如,在802.11bWLAN网络中,高达11Mbps可用于无线客户。 In such networks, the bandwidth can be used for reasonable Wireless customers, for example, in 802.11bWLAN network up to 11Mbps can be used for wireless customers. 该带宽足够用于承载语音。 This bandwidth is sufficient to carry voice. 此外,WLAN技术的广泛使用降低了该技术的价格。 In addition, the widespread use of WLAN technology reduces the price of the technology.

图1显示示范性无线广域网络(WWAN)100(也作为广域移动无线网络而公知)。 1 shows an exemplary wireless wide area network (WWAN) 100 (also as a wide area mobile wireless network known). WWAN100包括多个远程单元(手机)102,其与一个或多个基于天线的称为基站收发机系统(BTS)104的系统进行无线联系,基站收发机系统104发送无线信号到手机并从其接收无线信号。 WWAN100 comprising a plurality of remote units (mobile phone) 102, which is based on one or more antennas (BTS) system is called a base transceiver system of a wireless link 104, a base transceiver system handset 104 transmits a radio signal to and receives wireless signal. 多个BTS通过使用多种协议和技术(例如TDM,IP等)经固定链路108和称为基站控制器(BSC)106的控制器通信。 BTS controller via a plurality of fixed communication link 108 and a base station controller is called (BSC) 106 by using a variety of protocols and technologies (e.g., TDM, IP, etc.). 多个BSC和称为移动交换中心(MSC)110的、提供到广域交换电话网(WSTN)111的连接的交换机通信。 And a plurality of BSC as a mobile switching center (MSC) 110, there is provided a communication switch is connected to the wide area switched telephone network (WSTN) 111 a. WSTN包括信令链路113,例如SS7链路,以及公共交换电话网(PSTN)112。 WSTN comprising signaling link 113, such as SS7 links, and the Public Switched Telephone Network (PSTN) 112. 如MSC115所示,MSC可以包括控制平台117,用于控制信令链路上的消息,该消息可根据多种协议来传送,例如IOS,GSM A接口,IS41,GSM MAP等。 MSC115 As shown, the MSC may include a control platform 117, a control message on a signaling link, the message may be transmitted according to various protocols, e.g. IOS, GSM A interfaces, IS41, GSM MAP like. MSC115还可以包括媒体网关119,其和控制平台协作,用于控制PSTN112的承载电路。 MSC115 may further include a media gateway 119, which controls the platform and cooperate PSTN112 for controlling the bearer. 一些现有MSC,例如MSC115,还可在IP网络(例如IP网络120)上进行通信。 Some prior MSC, e.g. MSC115, may also communicate over the IP network (e.g., IP network 120).

MSC和与其相连的BSC以及BTS共同限定了一个覆盖区域,在此区域中,允许手机接收或发送电话呼叫。 MSC and BSC and BTS connected thereto together define a coverage area, in this region, allowing the phone to receive or send a phone call. 来自PSTN的对移动手机的呼入呼叫到达网关MSC,例如115,然后网关MSC路由该呼叫到称为服务MSC的MSC110,接收手机目前正在其覆盖范围内漫游。 An incoming call to the mobile phone call arrives from the PSTN gateway MSC, for example, 115, then the call is routed to the gateway MSC MSC110 called serving MSC, which is currently receiving phone roaming within the coverage area. 来自手机的呼出呼叫被路由到始发手机的服务MS109,然后从那里,呼叫或者经网关MSC被路由到接收移动手机的服务MSC,或经网关MSC路由到WSTN,从那里,WSTN路由该呼叫到(有线线路)手机。 Outgoing calls are routed from the handset to the originating Mobile Services MS109, and then from there, the call is routed via the gateway MSC or the serving MSC receives a mobile phone, or routed through the gateway MSC to WSTN, from there, WSTN route the call to the (wireline) phones.

在某些配置中,网关和服务MSC功能可用通过相同的物理实体来实现。 In some configurations, the gateway and serving MSC functions may be used to achieve the same physical entity. 允许用户在覆盖区域内漫游,并当漫游时,WWAN的不同实体协作,以确保漫游时保持手机的无线连接。 It allows the user to roam within the coverage area, and, when roaming, WWAN different entities cooperate to ensure that the phone is roaming when the wireless connection. 手机可以从一组BTS/BSC/MSC的覆盖区域漫游到另一组BTS/BSC/MSC的覆盖区域。 Phones can roam from the coverage area of ​​a group of BTS / BSC / MSC to another set of BTS / BSC / MSC coverage area. 前一组BTS/BSC/MSC被称为源,后一组被称为目标实体。 A front set of BTS / BSC / MSC is referred to as the source, after a group called the target entity. 规定了一系列的过程来协调手机从WWAN的源到目标实体的切换。 It provides for a series of procedures to coordinate the switch the phone from the source to the target entity WWAN. 作为切换过程的结果,发生手机位置的更新。 As a result of the handover process, update your phone position occurs. 这是通过手机发送位置更新消息到MSC来实现的,该MSC使用标准工业协议,例如IS-41,GSM-MAP等路由该消息到称为归属位置寄存器(HLR)114的注册处。 This update location message sent by the mobile phone to the MSC achieved, the MSC using standard industry protocols, such as routing IS-41, GSM-MAP message to the other is called a home location register Registry (HLR) 114 a.

在手机102和BTS104之间的通信使用了不同的空中接口技术。 Communication between the phone 102 and BTS104 use different air interface technologies. 这些技术包括码分多址(CDMA),全球移动通信系统(GSM),个人数字蜂窝(PDC)等,以及这些技术的各种扩展和增强,例如CDMA2000,通用移动陆地系统(UMTS),国际移动电话IMT-2000等。 These techniques include Code Division Multiple Access (CDMA), Global System for Mobile (GSM), Personal Digital Cellular (PDC) and the like, as well as various extensions and enhancements of these techniques, such as CDMA2000, Universal Mobile Terrestrial System (UMTS), an International Mobile telephone IMT-2000 and so on. 所有这些网络采用以上提及的已知实体,虽然使用不同术语、结构来收发电话呼叫。 All of these entities using known network mentioned above, although the use of different terms, the structure of a telephone call to the transceiver. 所有这些对于本领域普通技术人员都是已知的。 All of those of ordinary skill in the art are known.

图2显示示范无线局域网络(WLAN)200。 Figure 2 shows an exemplary wireless local area network (WLAN) 200. WLAN包括一个或多个地理区域(小区),称为基本服务组(BSS)202。 WLAN includes one or more geographical areas (cells), known as the basic service set (BSS) 202. 每个小区由称为接入点(AP)204的系统控制。 Each cell is controlled by a system called an access point (AP) 204 of. 通常,WLAN包括若干BSS,每个都有其相连的AP。 Typically, WLAN comprises several BSS, each with its attached AP. AP通常使用802.x WLAN技术中的以太网技术来与有线线路网络206相连。 802.x WLAN AP techniques commonly used Ethernet technology network 206 is connected to the wireline. AP和公司路由器208通信,208通常路由在公司网内或到公司网外的业务。 AP 208 and the communication company router, typically 208 to route traffic in the network outside the company, or to an office network. 允许无线数据客户210在规定BSS内漫游,并通过客户根据已知过程从一个AP到相邻AP的切换方式穿过规定的BSS。 210 allow wireless customers to data roaming within the specified BSS, the AP and the switching mode by a client through a predetermined BSS according to known procedures from a neighboring AP. 在典型的WLAN实施中,物理层使用多种技术,例如在802.11WLAN实施中,物理层可以使用红外线、2.4GHz频段内的跳频扩展频谱,或2.4GHz频段内的直接序列扩展频谱。 In the exemplary embodiment a WLAN, the physical layer using a variety of techniques, such 802.11WLAN embodiment, the physical layer can use infrared, frequency hopping spread spectrum in the 2.4GHz band, or direct sequence spread spectrum in the 2.4GHz band. 媒体访问层(MAC)除执行典型的功能外,还执行例如分组分段存储,重发和确认等附加功能。 A media access layer (MAC) to perform typical functions in addition, also perform additional functions packet fragmentation, retransmission acknowledgment and the like for example.

MAC层支持两种基本访问机制:分布协调功能(DCF)和点协调功能(PCF)。 MAC layer supports two basic access mechanism: Distributed Coordination Function (DCF) and Point Coordination Function (PCF). 在DCF中,基本访问机制是带冲突避免的载波检测多路访问(CSMA/CA)机制。 In DCF, the basic access with collision avoidance mechanism is a carrier sense multiple access (CSMA / CA) mechanism. 典型的例子是以太网,它是具有冲突检测(CD)机制的CSMA。 A typical example is Ethernet, it is CSMA (CD) mechanism has collision detection. 在CSMA协议中,想要发送的客户检测媒体,并如果发现媒体忙,即,被某些其他客户使用,则延迟发送;否则允许其发送。 In the CSMA protocol, the media want to send customers to detect, and if found that the medium is busy, that is, some other customers, the delay is sent; otherwise allowed to send. 总有可能两个客户检测到媒体空闲并开始发送,从而导致冲突;因此,在这种协议中,冲突避免和检测非常重要。 It is always possible to detect two customers and start sending free media, leading to conflict; therefore, in this protocol, collision avoidance and detection is very important. 例如,802.11WLAN使用冲突避免和检测机制。 For example, 802.11WLAN use of collision avoidance and detection mechanisms. 想要发送的802.11客户检测媒体,如果发现媒体忙,则延迟发送;否则开始发送。 802.11 detect media customers want to send, if we find the media is busy, delay sending; otherwise it starts sending. 接收机检测到对正确发送的接收(经循环冗余校验-CRC),如果发现接收满意,则发回确认。 Receiver detects the reception (by the cyclic redundancy check data_CRC) correctly transmitted, if found satisfactory reception, then sends back an acknowledgment. 确认的接收向发射机表示,发送已被正确接收。 Receiving a confirmation to the transmitter, the transmission has been received correctly. 如果没有接收到确认,发射机则会重发,直至接收到确认或发射机决定放弃发送为止。 If no acknowledgment is received, the transmitter will retransmit until an acknowledgment is received or the transmitter decided to abandon transmitted. 为进一步降低冲突的可能性,某些实施也使用虚拟载波检测机制。 To further reduce the possibility of conflict, certain embodiments also use the virtual carrier sense mechanism. 在此方案中,想要发送的客户首先通过发送请求发送(RTS)将其意图用信号通知目的接收机。 In this scenario, the customer wants is first transmitted by transmission request (RTS) which is intended to signal the receiver object. 接收机用清除发送(CTS)响应,为发射机和接收机有效“预留”媒体。 A receiver with a clear to send (CTS) response, the effective "reserved" for the transmitter and receiver media. 发射机现在可以发送预定的信息。 The transmitter can now send predetermined information.

在这些例子中,当想要发送的客户发现媒体忙时,客户延迟发送。 In these instances, when a customer wants to send the media found busy, the customer delayed transmission. 因此客户被迫重试以了解媒体的状态。 Therefore, customers are forced to retry to understand the state of the media. 在解决此问题的标准方法中,使用“指数降低过程(exponential back off procedure)”来确定重试的频率。 In the standard method of solving this problem, a "exponential reduction processes (exponential back off procedure)" to determine the frequency of retry. 该方法涉及选择随机数目并在重试之前等待许多时隙。 The method involves selecting a random number of time slots and a number of wait before retrying. 如果重试再次发现媒体忙,则重试次数呈指数减少。 If the retry find again the media is busy, the number of retries decreases exponentially. 该延迟过程还用在成功发送之后和各个重发之后。 The delay process is also used after each successful transmission and retransmission after.

当客户想要访问BSS(在打开电源之后或当第一次进入BSS时),不必从控制BSS的AP获得同步信息。 When a customer wants to access BSS (after the power is turned on or when you first enter the BSS), without having to obtain synchronization information from the AP control the BSS. 规定了两种方法用于客户获得此信息。 It provides two methods for customers to obtain this information. 在被动扫描方法中,客户等待从AP接收“信标帧”,该信标帧由AP定期发送。 In the passive scanning method, the client waits to receive the "beacon frame" from the AP, the beacon frame transmitted periodically by the AP. 信标帧包含同步信息。 The beacon frame includes the synchronization information. 在第二种方法中,被称为主动扫描,客户发送试探给AP,并等待对该试探的响应。 In the second method, referred to as active scanning, client transmits the AP to the probe, and waits for a response to the temptation. 一旦该站点发现AP,则需要对其鉴权。 Once the site is found to AP, the need for its authentication. 这要求在AP和客户之间交换信息以建立客户的鉴权。 This requires the exchange of information between the AP and the client in order to build customer authentication. 一旦完成鉴权过程,客户开始在客户和AP之间交换关于客户位置和BSS容量的信息的相关处理。 Upon completion of the authentication process, the client begins the exchange between the client and the AP information related to the processing position on the client BSS and capacity. 在完成这些相关处理时,客户准备好接收或发送数据。 Upon completion of these related processing, customer ready to receive or send data.

在PCF访问机制中,当检测到媒体在给定的称为单点帧间间隔(PIFS)的时间长度内空闲时,AP获得对该媒体的控制。 In the PCF access mechanism when the medium is idle is detected within a given length of time known as single inter-frame space (the PIFS) is, the AP gains control of the medium. 然后AP担当起协调程序的角色,开始轮询在由AP维护的“轮询列表”内列举的所有站点。 AP then assume the role of coordinator, began to poll all sites listed in the AP maintained by the "poll list." 当被轮询到时,允许站点进行发送。 When polled, allows transmission site. AP支持PCF模式的时间周期是无竞争的,从而可以为语音业务提供更好机会。 AP mode support PCF period of time is no competition, which can provide better opportunities for voice service. AP必须交替DCF和PCF周期。 AP must alternate DCF and PCF period. 所有这些对于本领域普通技术人员都是已知的。 All of those of ordinary skill in the art are known.

因此,需要一种用于网际互联WLAN和无线广域网络(WWAN)的方法,以在两个网络之间进行具有完全移动管理的语音通信,并保留WWAN环境中的PBX特征。 Thus, the method and internetworking WLAN wireless wide area network (WWAN) is a need for a speech communication having to completely moved between two network management, and retention feature WWAN PBX environment.

具体实施方式 Detailed ways

本发明的优选实施例提供WLAN和WWAN之间的语音网际互联,并有效统一了这两种完全不同的技术。 Preferred embodiments of the present invention provide a voice internetworking between WLAN and WWAN, and the effective unified two completely different technology. 因此,用户无需忍受和多个手机、地址以及语音邮箱相关的问题。 Therefore, users do not need to endure the problem and multiple cell phones, and voice mail address associated. 如下所述,在某些实施例中,具有对WLAN客户的某些相关修改的WWAN的网关MSC(GMSC)交换机为该统一提供了必需的逻辑。 As described below, in some embodiments, WWAN gateway has modified some of the relevant WLAN client MSC (GMSC) for the unified switch provides the necessary logic. 实质上,GMSC同时用作WLAN语音业务的服务MSC。 Essentially, GMSC both as WLAN voice service MSC.

图3显示本发明的示范性实施例。 3 shows an exemplary embodiment of the present invention. WWAN组件与如以上结合图1所描述的相同,除了MSC302包括一些新的以下讨论的网际互联逻辑之外,以处理WLAN和WWAN的统一,使其用作一个宏网络300。 WWAN assembly as described above in connection with FIG. 1 is the same, except MSC302 includes new internetworking logic discussed below, to process the unified WWAN and WLAN, so that it is used as a macro network 300. 除了其他之外,MSC302用作WLAN的服务MSC。 Among other things, MSC302 as a WLAN service MSC. 现在WLAN和WWAN通过IP链路304有效连接。 Now linked WLAN and WWAN 304 via the IP link. 在该组IP链路304上承载从公司到MSC302的IP接口的到WLAN和来自WLAN的语音业务以及相关信令和控制消息。 Group carried on the IP link 304 from the company to the MSC302 IP interface to the WLAN from the WLAN and voice services and associated signaling and control messages. WLAN组件也和上述的相同,除了手机或无线数据客户310包括多模式装置之外,其能操作在WLAN或WWAN环境中,如下所述。 And also the same as the above-described components WLAN, wireless phone or data in addition to the client 310 includes a multi-mode device than that can operate in the WWAN or WLAN environment, as described below.

MSC302允许完成WWAN100和WLAN200的客户之间的电话呼叫。 MSC302 allowed to complete a telephone call between WWAN100 and WLAN200 customers. WLAN客户能自由地在WLAN环境中漫游,还可在WWAN环境中漫游,而无需要求用户有任何手动干预。 WLAN clients can freely roam in a WLAN environment, but also roaming WWAN environments, without requiring any manual user intervention. 从WLAN到MSC302的语音业务可使用任何已知的语音编码技术。 Voice traffic from the WLAN to the MSC302 may be used any known speech coding technology. 对于CDMA网络,可使用增强可变速率编解码器(EVRC),对于GSM网络,可使用自适应多速率(AMR)编码。 For CDMA networks, using Enhanced Variable Rate Codec (the EVRC), for a GSM network, using an adaptive multi-rate (AMR) coding. 然后在IP链路304上将编码后的语音承载为RTP/UDP/IP分组。 Then the voice IP 304 on the link after the bearer is encoded RTP / UDP / IP packets. 从WLAN200到MSC302的控制和信令消息也承载在IP链路304上。 From the control and signaling messages to WLAN200 MSC302 also carried on the IP link 304. 在某些实施例中,以会话初始协议(SIP)消息的格式承载控制和信令消息,并具有被描述为本发明一部分的用于控制手机切换的附加信息元素(IE)。 In certain embodiments, the format to Session Initiation Protocol (SIP) message and the bearer control signaling message, and a part of the present description have been used to control the additional information element (IE) of the phone switches to the invention.

通过使用能操作在WLAN或WWAN环境中的多模式手机310,使在某些实施例中的语音网际互联变得容易。 By using WLAN or WWAN can operate in a multi-mode mobile phone environment 310 enables voice internetworking In certain embodiments becomes easy. WLAN和WWAN(多模式)电话310在任意时刻都能自动确定它是否能使用WLAN接入,而非宏网络载波(GSM,CDMA,UMTS,TDMA,PDC等)。 WLAN and WW (multimode) phone 310 can automatically determine whether it can access the WLAN at any given time, rather than the macro network carriers (GSM, CDMA, UMTS, TDMA, PDC, etc.).

可通过在准许802.1b/a频谱(对于802.11b/802.11g是2.4GHz频段,对于802.11a是5GHz频段)内检测RF能量推断出是否存在WLAN。 May be permitted by 802.1b / a spectrum (for 802.11b / 802.11g is 2.4GHz band for 802.11a is 5GHz band) in the detection of RF energy to deduce whether there is WLAN. 如图4所示,移动站310可在相关频谱内开始RF能量的检测402。 4, the mobile station 310 may begin 402 RF energy detected in the relevant frequency spectrum. 在成功的能量检测之后,移动站可通过两种方法之一来检测是否出现可用WLAN200:·被动扫描:移动站310搜索802.11x AP 204广播的信标帧·主动扫描:移动站310发送试探请求帧,并等待来自AP204的试探响应帧。 After a successful energy detection, the mobile station can be detected by one of two methods the WLAN 200 whether there is available: · passive scanning: the mobile station 310 searches 802.11x AP 204 broadcasts a beacon frame · Scan active: the mobile station 310 transmits probe request frame, and waits for the probe response frame from AP204.

作为信标帧或试探响应的一部分,AP发送标识AP204的SSID(1-32八位组长度字符串)。 As part of a beacon frame or probe response, AP transmits the identification AP204 SSID (1-32 octets of the string). 移动站310将此SSID和SSID列表(可能包括范围)比较,并如果匹配,则推断WLAN200是可获得接入的有效网络。 The mobile station 310 of this SSID and SSID list (possibly including range) are compared and if a match is inferred WLAN200 effective network access is available. 移动站310在成功SSID匹配之后通过鉴权过程。 The mobile station 310 after a successful authentication process by matching SSID. 如果鉴权成功,则移动站继续进行相关处理,借此,移动站作为有效和合法客户(节点)加入WLAN网络。 If the authentication is successful, the mobile station continues correlation process, whereby the mobile station as an effective and legitimate client (node) to join the WLAN network.

移动站310是先验的,提供有有效SSID列表和SSID范围。 The mobile station 310 a priori, there is provided effective range SSID and SSID list. SSID比较避免了移动站进入它永远不可能被鉴权的运行WLAN网络的鉴权或相关处理。 SSID compare avoid the mobile station enters it can never authentication or authentication-related processes are running WLAN networks. 例如,假设移动站MS1属于使用SSIDEn1SSID1的公司E1。 For example, assume that the mobile station MS1 ​​using SSIDEn1SSID1 companies belonging to E1. 当移动站进入公司E1时,信标搜索成功,进一步发生SSID匹配,从而移动站进行鉴权处理。 When the mobile station enters the company E1, the beacon search is successful, matching the SSID further occurs, so that the mobile station authentication process. 在鉴权成功时,它继续进行到相关处理,并获得对WLAN服务的接入。 When authentication is successful, it continues to correlation processing, and gain access to WLAN services. 当同一移动站MS1进入另一碰巧也有有效802.11WLAN但具有不同SSID(例如En2SSID2)的公司时,该SSID和移动站内的SSID不匹配,从而移动站不会试图开始鉴权(因此认为该WLAN服务不可用)。 When the same happened to another mobile station MS1 ​​enter a valid 802.11WLAN but also when the company has a different SSID (eg En2SSID2), which SSID and SSID within the mobile station does not match, so that the mobile station will not attempt to start authentication (therefore considered that the WLAN service unavailable).

在CDMA网络的例子中,在移动站内SSID的提供可通过使用基于空中的提供程序(over the air provisioning procedures)(OTASP/OTAPA)从宏网络300开始,或在GSM/UMTS网络(使用短消息服务)中也是一样。 In the case of CDMA network, in the mobile station SSID provided by the use of based provider (over the air provisioning procedures) (OTASP / OTAPA) starts from the macro network 300 or the GSM / UMTS network (using a short message service ) it is also the same. 为防止宏网络内SSID的窃听,可使用与在移动站中用于宏网络鉴权/加密相同的密钥(A-密钥或SSD)来加密该消息自身。 To prevent eavesdropping SSID within a macro network, may be macro using the same network authentication / encryption key (or key A- SSD) in the mobile station encrypt the message itself.

周期检测和随后发现WLAN的存在影响了移动站的电池寿命。 Cycle detection and subsequent WLAN found impact battery life of the mobile station. 期望最小化电池消耗,在多模式电话中实现此效果的一种方式是最小化检测或发现尝试的次数,同时如果可用,保持跳到公司WLAN的能力。 It is desirable to minimize battery consumption, one way to achieve this effect in the multi-mode phone is to minimize the number of attempts detected or found, and if available, to maintain the ability to jump to a corporate WLAN. 对于使用多模式移动站310能降低检测/发现尝试次数的两种观察:·可用于用户的公司无线LAN服务的区域数目是有限的;例如,公司用户可能仅限于在其公司位置内才可以访问其WLAN服务。 For multi-mode mobile station 310 to reduce the detection / observation found that the two attempts: • the number of regions may be used to the user's wireless LAN service company is limited; for example, a user may be limited to the company can access the company in its position its WLAN service.

·多模式移动站总试图保持与宏网络(CDMA,GSM,UMTS等)的连接。 · Total multi-mode mobile station attempts to remain connected with the macro network (CDMA, GSM, UMTS, etc.). 例如,检测到有效IS-95/IS-2000信号的CDMA电话总试图向IS-41核心网络注册;检测到GSM/UMTS有效信号的GSM/UMTS电话总试图向GSM-MAP核心网络注册。 For example, detection of a valid IS-95 / IS-2000 CDMA phone signal is always attempting to register with IS-41 core network; detect the GSM GSM / UMTS valid signal / UMTS phone always attempting to register GSM-MAP core network. 作为注册结果,宏网络和移动站都已知的小区ID表示移动站的当前位置。 As a result of registration, the macro network and the mobile station are aware of the cell ID indicates the current position of the mobile station.

通过联系以上两个事实,宏网络300可以确定移动占310何时应当试图检测或发现公司WLAN。 By contacting the above two facts, the macro network 300 can determine the movement should be accounted for when trying to detect or find 310 companies WLAN. 如图5所示,在本发明的优选实施例中,宏网络300在成功实现网络注册时,可以发送涉及检测或发现处理的502信息给移动站310。 As shown in FIG 5, in this embodiment, when the macro network 300 successfully registered to a network, may transmit or detect discovery relates to processing information 502 to the mobile station 310 in the preferred embodiment of the present invention. 该信息包括宏网络小区ID,在该小区中移动站310应当试图检测或发现402'公司WLAN。 The network information including macro cell ID, a cell in which the mobile station 310 should attempt to discover or detect 402 'company WLAN. 该小区ID是总测量,因此可以覆盖非常大的区域(在农村/郊区区域大约有几平方英里)或很小的区域(在密集的城市区域大约有几百平米)。 The total cell ID is measured, it is possible to cover a very large area (approximately in rural / suburb area of ​​a few square miles), or a small area (approximately several hundred square meters in dense urban areas).

作为本发明的方法的示范显示,考虑一个CDMA(IS-95)用户,他同时也是位于马萨诸塞吐克斯伯利(Tewksbury,Mass)的大厦W内的802.11服务的公司用户。 As an exemplary method of the present invention display, we consider a CDMA (IS-95) the user, who is also a user company located in Massachusetts spouting 802.11 services within Tewksbury (Tewksbury, Mass) building W. 当该用户进入吐克斯伯利的CDMA交换区域时,其IS-95电话开始网络注册。 When the user enters the CDMA exchange region Tewksbury, the IS-95 telephone network registration starts. 作为该注册的一部分,宏网络300确定用户可能进入大厦W内的WLAN服务的覆盖区域;即,宏网络将用户和大厦W都在吐克斯伯利交换区域内的信息相关起来。 As part of the registration, the macro network 300 determines that the user may enter the coverage area of ​​WLAN services in the Building W; that is, the macro network users and building W in Tewksbury related to the exchange of information within the region together. 宏网络现在提供W大厦所处的502小区ID信息给用户的移动站310以及应当开始WLAN检测的触发。 The mobile station 310 now provides the macro network 502 W building located cell ID information to a user and the WLAN should start trigger detected. 当接收到该信息时,移动站开始扫描802.11信标,特别是寻找和大厦W内的AP的SSID列表的匹配。 When receiving the information, the mobile station begins scanning 802.11 beacon, in particular in the building and W match with an SSID of the AP list. 该检测直至用户进入BSS202才会成功。 The detection until the user enters BSS202 to be successful. 当成功的从AP204检测到信标时,用户的移动站310撤销宏网络300的注册,并向WLAN200的服务MSC注册。 Upon successful AP204 is detected from the beacon, the mobile station 310 user's registration revocation macro network 300, and registered service WLAN200 MSC. 当移动站在WLAN200内漫游时,它继续检测WWAN100和WLAN200的RF能量强度。 When the mobile station roams within WLAN200, it continues to detect the intensity of the RF energy and WLAN200 of WWAN100. 如果检测到WLAN RF能量强度低于某阈值且WWAN强度高于阈值,则它开始对宏(WWAN)网络100的注册过程。 If the RF energy intensity detected WLAN and WWAN below a certain threshold intensity above a threshold, then it begins the registration process of the macro (WWAN) network 100.

如前所述,宏网络300的小区ID可指定非常大的地理区域。 As described above, the cell ID of the macro network 300 may specify a very large geographical area. 如果小区ID和小地理区域相关,则最小化移动站内的功率消耗的机会增加了,因为检测或发现处理仅限于较小的地理区域。 If the cell ID and a small geographic area, then the opportunity to minimize power consumption in a mobile station increases because the processing is limited to the detection or discovery smaller geographic area. 在某些实施例中,可使用集成有GPS(地理定位卫星)有效信息的移动站。 In certain embodiments, it may be integrated with valid information using GPS (geographic positioning satellite) mobile station. 由于GPS信息相比于小区ID信息更加准确,所以GPS信息的使用将进一步减少需要开始检测或发现处理的地理区域,从而更加节省移动站的功耗。 Since the GPS information as compared to the cell ID information is more accurate, the use of GPS information will reduce the need for further tests or geographical area discovery process, thereby saving even more power consumption of mobile stations.

由宏网络提供给移动站的小区ID列表可以不仅包括用户可以漫游进的公司位置,还潜在的包括其他“公司”或“公共区域”。 The macro cell ID list provided by the network to the mobile station may include not only a user may roam into the business location, potentially further comprising other "Company" or "public area." 例如,宏网络服务提供商可能和例如餐厅或宾馆的公共公司LAN具有漫游协议。 For example, the macro network and service providers such as restaurants or hotels may be a public company LAN has a roaming agreement. 参考图6,当用户310向宏网络注册时,不仅接收用户公司所在的602小区ID,而且还接收位于相同交换区域内的公共LAN的小区ID是有益的。 Referring to FIG 6, when a user registers with the macro network 310, 602 receives not only the cell ID where the user companies, but also receives the cell ID in a common LAN within the same exchange area is beneficial.

使用标准短消息服务(SMS)、或通过使用基于服务控制点(SCP)的逻辑,或通过修改HLR或使用代理HLR实体来实现位置信息或在移动站310内开始(或停止)搜索WLAN信标的更直接的指令的传送。 Using a standard short message service (SMS), or by implementing a location information by modifying the HLR or using a proxy HLR entity-based Service Control Point (SCP) logic, or or begins in the mobile station 310 (or stop) Search for WLAN beacon more direct transfer instruction. (参见,例如美国专利申请09/845703的代理HLR的例子,其在2001年4月30日申请,在此结合其全部内部作为参考。)当移动站310向MSC/HLR注册时,宏网络可以作为具有特定类型的SMS(短消息服务)发送小区ID列表,信标搜索/停止指令等。 (See example, U.S. Patent Application No. 09/845703 e.g. HLR agent, which in the application on April 30, 2001, incorporated herein by reference in its entirety inside.) When the mobile station 310 registers with the MSC / HLR, the macro network may transmitting cell ID list as SMS (short message service) having a specific type of beacon search / stop instruction or the like. 在对由移动站310开始的位置更新的成功响应后发送此SMS消息。 Sending the SMS message after a successful response to the start position of the mobile station 310 by the update.

其它变化本发明的基本机制是当其在呼叫期间从WLAN漫游到WWAN环境中的移动站的切换。 Other variations of the present invention, the basic mechanism is that when it roams during a call handover from WLAN to WWAN environment of the mobile station. 该机制假定存在连接WLAN和使用例如IS-41的标准移动管理协议的WWAN交换机的主干线。 The trunk connection mechanism is assumed that there, for example, WLAN and WWAN switch using standard mobility management protocol is IS-41. 图29显示一方法的示范实施例,该方法用于当缺少此类连接性时影响切换,结合图30讨论示范逻辑。 29 shows an exemplary embodiment of a method, the method is used when the absence of such impact switch is connected, in conjunction with FIG. 30 discussed exemplary logic. 如图所示,并根据本发明的先前描述,当参与和A方的电话呼叫时,该A方可能使用PSTN手机2902或WWAN移动手机2904,移动站310(MS)检测WLAN和WWAN环境,并确定WLAN环境强度逐渐减弱,而WWAN环境强度增强。 As shown, and in accordance with the present invention previously described, when the telephone call participants and the A-party, the A-party may use the PSTN or a mobile phone 2902 2904 WWAN mobile handset, the mobile station 310 (MS) detects the WLAN and WWAN environment, and WLAN environment to determine the intensity gradually weakened, and WWAN environments strength enhancement. 在此方案中,移动站310可以确定3002即将进行切换。 In this embodiment, the mobile station 310 may determine 3002 the upcoming handover. 当做出该决定时,移动站310请求3004WLAN交换机302给它发送临时本地电话号码(TLDN)。 When making this determination, the mobile station 310 requests 3004WLAN switch 302 sends the temporary local number (the TLDN) to it. 如本领域技术人员所知,其他电话交换机可使用TLDN来路由呼叫到发送该TLDN的交换机。 As those skilled in the art, may be used TLDN other telephone exchange to route the call to the switch to send the TLDN. 当接收到TLDN时,移动站310继续漫游,以及移动站310或WLAN交换机或二者发现3006移动站310和WLAN交换机之间的连接性已消失。 Upon receiving the TLDN, the mobile station 310 continues to roam, and the mobile station 310 or WLAN switches or both found in the connection between mobile station 310 and 3006 WLAN switch have disappeared. 在此偶然事件中,WLAN交换机暂时将A方置于3008在线(WLAN可以通过预录的广播通知A方事情的进行状态)。 In this fortuitous event, WLAN switch temporarily placed 3008 A party-line (WLAN A party may notify the state of things by broadcasting pre-recorded). 当检测到WWAN环境并成功完成在WWAN环境中的注册时,移动站310请求将TLDN用作目的地的呼叫(被叫方)。 When detecting the WWAN environment and successfully completed registration WWAN environment, the mobile station 310 requests TLDN as the call destination (called party). WWAN交换机使用它的基于TLDN的路由逻辑路由3010该呼叫到WLAN交换机。 WWAN TLDN based switch uses its routing 3010 routes the call to the logical WLAN switches. WLAN交换机认出3012该TLDN,并将A方连接到呼入呼叫。 WLAN switches 3012 recognizes the TLDN, and party A is connected to the incoming call. 从而,虽然有中断,但是A方和MS可以继续正进行的呼叫。 Thus, while there is an interrupt, the A side and the positive MS may continue the call.

许多公司利用专用小交换机(PBX)。 Many companies use private branch exchange (PBX). PBX系统通常提供特征丰富的环境给附加的电话,例如缩位拨号,多方呼叫等。 PBX systems typically provide a rich environment for additional telephone features, such as abbreviated dialing, multiparty calls. 在本发明的某些实施例中,可和PBX系统一起使用WLAN交换机。 In certain embodiments of the present invention may be used with the switch WLAN and PBX system.

图31显示此种配置的示范实施例。 31 shows an exemplary embodiment of this configuration of Fig. WLAN200通过标准支持接口(例如ISDN PRI)连接到PBX3102。 WLAN200 PBX3102 connected to the support via standard interfaces (e.g., ISDN PRI). 从连接到PBX的手机发起的并且目的地是WLAN控制的手机的电话呼叫可以经该标准接口传送到WLAN交换机3104。 From mobile phone connected to a PBX initiates a WLAN and a destination mobile telephone call control interfaces can be transmitted to the switch 3104 via the WLAN standard. WLAN交换机可使用该标准接口来传送电话呼叫到PBX。 WLAN switches can use the standard interface to transmit a telephone call to the PBX.

移动站310可使用WLAN空中接口进行呼叫,此类呼叫经LAN206的IP链路在有线LAN206上被传送到WLAN交换机2904。 The mobile station 310 may use WLAN air interface calls, such calls via the IP link LAN206 WLAN switch 2904 is transmitted to the wired LAN206. 交换机3104然后在ISDN PRI链路3106上传送该呼叫信令(以及最终是语音或其他数据)到PBX交换机3102,该交换机处理呼叫,就好像该呼叫来自PBX电话3108似的,并因此提供PBX服务给移动站。 Switch 3104 is then transmitted on the ISDN PRI call signaling link 3106 (and ultimately voice or other data) to the PBX switch 3102, the switch processes the call, if the call from the PBX phone 3108-like, and thus to provide PBX services to the mobile station. 例如,如果移动站使用缩位拨号方案,则PBX会做出适当连接,并经PBX交换机3102传送该通信。 For example, if the mobile station using abbreviated dialing program, the PBX will make the appropriate connections, 3102 and transmitting the communication via the PBX.

对于内部呼叫,WLAN交换机3104实质上用作协议转换器,接收作为IP的移动站信令和数据,并经ISDN PRI链路经其作为ISDN信息提供给PBX。 For an internal call, WLAN switch substantially as a protocol converter 3104, a mobile station receives signaling and IP data, and supplied to the PBX via the ISDN PRI links via which information as ISDN.

对于外部呼叫,某些实施例如下操作。 For external calls, certain embodiments operates as follows. WLAN交换机3104检测到移动站期望呼叫外方。 WLAN switch 3104 detects that the mobile station calls a desired outward. 这可以通过分析被呼叫方信息来世旭,例如察看是否使用某种拨号方案信息,例如在被呼叫号码的前面加上号码“9”。 This caller information may be analyzed hereafter Xu, for example, to see whether the dialing plan to use some information, for example in front of the called number plus the number "9." 在此例子中,交换机3104和WWAN交换机3112通信,并请求稍后和被呼叫方信息相关的TLDN,被呼叫方信息例如是被呼叫方号码“123”。 In this example, the switch 3104 and the switch 3112 WWAN communication, and requests the later and the TLDN associated caller information, the caller information, for example, called party number "123." 当接收到此类TLDN时,交换机3104然后使用该TLDN经链路3106请求PBX交换机3102把和该移动站相关的电路连接到WWAN交换机3112,即请求PBX把呼叫连接到用作被呼叫方的TLDN。 When receiving such a TLDN, and then use the switch 3104 via link 3106 TLDN 3102 requests the PBX and the mobile station circuit associated with the switch 3112 is connected to the WWAN, i.e. the call connection request to the PBX of the called party as TLDN . WWAN交换机3112认出具有TLDN的该呼入呼叫请求是到先前存储的被呼叫方号码123的(即WWAN交换机3104将发送的TLDN和先前从WLAN交换机3104接收的被呼叫号码“123”相联系),并如标准路由逻辑所述,路由该呼叫到被叫方号码“123”。 WWAN switch 3112 recognizes that the incoming call request with a TLDN is to (and previously received TLDN from the WLAN switch 3104 called number "123" that is linked to the switch 3104 sends a WWAN) previously stored called party number 123 and, as the standard routing logic, to route the call to the called party number "123." 从而,PBX3102请求到目的地TLDN的呼叫,但WWAN交换机3112认出该呼叫实际上是到目的地“123”的,并路由该呼叫到“123”。 Thus, PBX3102 TLDN call request to the destination, but the switch 3112 recognizes that the WWAN call to the destination is actually "123", and route the call to the "123." TLDN用作标识符,识别在IP链路3114上的“信令”以及来自PBX的在ISDNPRI链路3110上的请求。 TLDN as an identifier identifying the IP link 3114 "signaling" and a request from the PBX link in ISDNPRI 3110. 这样,任何后续信令或和移动站310相关的链路3114都和链路3110上的正确承载电路相联系。 Thus, any subsequent signaling or mobile station 310 and associated links 3114 and are on the correct bearer link 3110 associated.

在移动管理方面,可如上所述进行漫游。 In the mobile management, roaming may be as described above. 如果在WWAN交换机3312和WLAN交换机3104之间存在移动管理主干线,则如上所述进行硬切换。 If there is the main trunk between the mobile management WWAN and WLAN switch 3104 switches 3312, a hard handover is performed as described above. 该逻辑显示在图12-14以及19-21中,并有在不同网络条件下的相关硬切换说明。 The logic shown in Figures 12-14 and 19-21, and the hard handover related instructions under different network conditions. 在缺少此类主干线时,可将TLDN用作切换机制来进行切换,即当移动站漫游到WWAN区域并失去和WLAN的无线连接时,移动站通过使用TLDN自动重新连接该呼叫来执行切换。 In the absence of such a trunk line, the switching mechanism may be used as the TLDN to switch, i.e. when the mobile station roams to the area and WWAN and WLAN losing wireless connection, the mobile station performs handover by automatically reconnect the call using the TLDN. 在此例子中,在呼叫建立期间,或如上所述响应于移动站请求,WLAN交换机可以通知移动站要使用的TLDN(例如WLAN交换机3104缓存TLDN并等待移动站的请求)。 In this example, during call set up, as described above, or the mobile station in response to the request, the WLAN switch TLDN may inform the mobile station to be used (e.g., WLAN switches 3104 and wait for a request buffer TLDN mobile station).

在此配置中,WWAN MSC3112固定该呼叫。 In this configuration, WWAN MSC3112 fixing the call. 某些变化是可能的。 Some variations are possible. 例如,在切换期间,WWAN MSC可拆掉先前所使用的到PBX的链路。 For example, during handover, WWAN MSC link may be removed previously used to the PBX. 这对于两方呼叫是有效的。 This two-party call is effective. 然而,为支持PBX域内多方参与的呼叫,必须保持到PBX的链路。 However, to support multi-domain PBX call involved, it must be kept to a PBX link. 在此种情况下,WWAN MSC3112必须将移动站临时接入现有呼叫。 In this case, WWAN MSC3112 have temporary access to the mobile station existing call.
