无线互联网络话音与数据通信的结构 Structure wireless Internet voice and data communications

本发明涉及互联网上实现话音和数据服务的网络结构,更准确地说,涉及一种网络结构,其中部署多个互联网基站,每个互联网基站具有用于用户话音和数据通信的与互联网中心局连接的大容量中继线、综合业务数据网出入口和无线收发信机。 The present invention relates to achieve voice and data services on the Internet network architecture and, more particularly, relates to a network structure, wherein a plurality of Internet base stations deployed, each having a base station for connecting Internet user's voice and data communications with the central office Internet The high-capacity trunk, integrated services digital network gateway and wireless transceivers.

众所周知,互联网电话可以实现互联网上话音到话音的通信,如图1所示,这是用本地电话公司的设备实现的(有时是长途载波)。 As we all know, the Internet telephony can achieve voice communication over the Internet to voice, as shown in Figure 1, which is the local telephone company's equipment to achieve the (sometimes long distance carrier). 也就是说,第一用户计算机11通常借助于调制解调器12拨号而进入本地电话交换机13。 In other words, the first user computer 11 typically by means of a modem dial 12 and 13 to enter the local telephone exchange. 第一个计算机11装备了麦克风16和喇叭17。 The first computer 11 is equipped with a microphone and a speaker 17 16. 本地电话交换机发送这个“呼叫”(即,已调制话音数据)到互联网服务器14,后者在通过电话线15建立与计算机11的双向通信之后,把分组话音数据放在互联网19的分组交换网络里。 Local telephone switch sends the "call" (ie, modulated voice data) to the Internet server 14, which after passing through the telephone line 15 to establish two-way communication with the computer 11, the packet voice data on the Internet in a packet-switched network 19 . 在远端,第二用户计算机11(也有调制解调器12、麦克风16和喇叭17)同样建立与另一个连接互联网服务器14的本地交换机13的双向通信。 At the far end, a second user computer 11 (also have a modem 12, a microphone 16 and speaker 17) to establish a connection to Internet servers the same local exchange 13 of 14 two-way communication with one another. 分组话音数据在互联网服务器14之间的互联网上来回传送,发送(或接收)已调制话音数据到(或从)各自的计算机11。 Packet voice data sent back and forth between the Internet 14 Internet servers, send (or receive) modulated voice data to (or from) their computers 11. 调制解调器12将已调制话音数据解调,以便在喇叭17上再现声音。 Modem 12 demodulates the modulated voice data, so that the reproduced sound in the speaker 17.

现在将参考图5-7的流程图,介绍本发明的无线互联网络的操作。 Referring now to the flowchart of FIG. 5-7, describes a wireless network operating according to the present invention.

图5介绍移动用户通过拨从互联网基站获得的目的地号码进行(开始)呼叫的情况。 Figure 5 shows the case of mobile users (start) the call by dialing the destination number obtained from the Internet station. (步骤501)。 (Step 501).

控制单元47首先经由T1/E1组合器电路访问原始位置寄存器HLR(和/或访问位置寄存器VLR),以便请求被叫用户号码约定(Indentification)并确定所知最近被叫移动用户位置(步骤502)。 The control unit 47 first accesses the home location register HLR (and / or visitor location register VLR) via a T1 / E1 combiner circuitry, in order to request the called subscriber number convention (Indentification) and determines the called mobile subscriber recently known location (step 502) . 如果被请求的被叫用户号码没有在HLR中找到,HLR发回适当的报文到IBS(步骤503和504)。 If the called subscriber number is requested was not found in the HLR, HLR sends back the appropriate message to the IBS (step 503 and 504). 此时,所述呼叫请求被IBS认为是移动点-陆地线路装备定向呼叫。 In this case, the call request is considered to be a mobile point IBS - Directed Call landline equipment. IBS经由本地交换机提供的ISDN连接把这种呼叫请求连接到本地交换机(步骤505)。 IBS via an ISDN connection to the local exchange to provide such a call requesting a connection to the local exchange (step 505). 当被叫用户处于摘机状态(off-hook)时(步骤506),建立连接,并且IBS开始发送64千比特每秒PCM话音给被叫用户(步骤507)。 When the called user is off-hook (off-hook) (step 506), to establish a connection, and start sending IBS 64 kilobits per second PCM voice to the called user (step 507). 从这点来看,所有呼叫信号方式都象标准ISDN话音和数据呼叫一样被处理。 From this point of view, all calls are signaled as standard ISDN voice and data calls are treated the same.

另一方面,当以肯定的确认回答IBS对HRL的请求时,则经由互联网可到达被叫用户。 On the other hand, when the answer to positive confirmation request for IBS HRL when the called subscriber can be reached via the Internet. 此时,IBS开始基于互联网的话音呼叫连接(步骤508)。 At this time, IBS start Internet-based voice call connection (step 508). 当呼叫建立程序表明被叫用户已经准备说话时(步骤509),它将分组压缩语音发送到被叫用户的地址(步骤510)。 When the call establishment procedure indicates that the called user is ready to speak (step 509), the compressed voice packet will be sent to the called user's address (step 510). 同时,被叫用户在主叫用户的方向上同样这样做。 Meanwhile, the called user in the same direction on the caller to do so.

现在参考图6a,当呼叫请求从公用交换电话网络到达本地交换机(中心局)(步骤601)时,本地交换机查找自己的数据库确定被叫号码是关于连接到交换机固定终端,还是别的特殊东西,例如移动终端的标准呼叫(步骤602)。 Referring now to Figure 6a, when a call request from the public switched telephone network to the local exchange (central office) (step 601), the local exchange to find its own database to determine the called number is on a fixed terminal connected to the switch, or other special things, a mobile terminal such as a standard call (step 602). 如果不是移动终端,那么呼叫用户以众所周知的方式进行(步骤603)。 If not the mobile terminal, then the calling user in a well known manner (step 603). 如果是移动步骤,那么ISDN交换机的国内互连网络(National IN)能力触发HLR查询(步骤604)。 If the moving step, the ISDN switch domestic interconnection network (National IN) the ability to trigger HLR query (step 604). 所述HLR识别包含最近所知的被叫移动用户位置的IBS(步骤605)。 The HLR will identify the IBS (step 605) the latest known location of the called mobile subscriber. 基于这种报文,本地交换机开始向已识别的IBS的ISDN呼叫请求(步骤606),所述IBS把这种请求转变为对被叫移动用户的寻呼请求。 Based on this message, the local exchange to the identified start of IBS ISDN call request (step 606), the IBS to this request into the called mobile subscriber's paging request. 如果移动用户响应此寻呼请求,则用64千比特每秒的PCM话音建立连接(步骤607)。 If the mobile user responds to this paging request, then with 64 kilobits per second PCM voice connection is established (step 607).

图6b介绍基于互联网的呼叫请求。 Figure 6b describes a call request based on the Internet. 呼叫被传送至正确的IBS,因为,如上所述(步骤502,图5),始发IBS向HLR查询关于被叫移动用户的最近所知位置。 The call is transferred to the correct IBS, because, as described above (step 502, FIG. 5), the HLR query originating IBS recently known locations of the called mobile. HLR响应这个包含被叫用户的IBS的互联网地址的查询。 HLR response to this query contains the called user's Internet address of IBS. 这样,目的地IBS(即,被叫用户的IBS)直接从始发IBS接收报文,连同被叫用户终端地址(步骤608)。 Thus, the destination IBS (i.e., the called user IBS) directly receives packets from the originating IBS, along with the address of the called user terminal (step 608). 当被叫用户的服务IBS接受这请求时,它提取被叫用户的号码(步骤609)并把它转换成寻呼报文(步骤610)。 When the called subscriber's service IBS accept this request, it extracts the called subscriber's number (step 609) and converts it into a paging message (step 610). 当被叫移动用户响应这种寻呼时(步骤611),IBS通过利用压缩语音分组通向中心局的互联网连接,把被叫用户连接到主叫用户。 When the called mobile subscriber in response to this page (step 611), IBS compressed speech packet by using the Internet connection leading to the central office to connect the called user to the calling user.

现在参考图7描述交接情况。 Now be described with reference to FIG. 7 handover situation. 当移动用户离开IBS服务的覆盖范围(即“源”IBS)时,为了给用户提供不间断服务必须进行交接。 When the mobile user leaves IBS service coverage (ie, the "source" IBS), in order to provide uninterrupted service to users must be handover. 基于各传输信号参数,移动用户连续地把目标站清单传达到源IBS,所述清单代表其最大可能的服务IBS的概况(步骤701)。 Each transmission signal parameters based on the mobile user to the destination station list is continuously conveyed to the source IBS, the list of services on behalf of its maximum possible overview of IBS (step 701). 当源IBS认为交接正常时(步骤702),源IBS从移动用户提供的清单中选择最好的目标站(步骤703)并经由它的互联网连接发送给那个目标站一种交接请求报文(步骤704)。 When the source IBS considered normal handover (step 702), the source IBS select the best target station (step 703) from a list provided by the mobile user and sent to the destination station is connected via its Internet a handover request message (step 704). 目标IBS可能或可能不接受这个请求(步骤705)。 IBS target may or may not accept the request (step 705). 如果目标IBS不接受这个请求,下一个更合适的目标站被源IBS选择(步骤703)然后将交接请求传送至那里(步骤704)。 If the target IBS does not accept this request, the next station is a more suitable target source IBS selected (step 703) and then transmits the handover request to there (step 704).

如果目标IBS接受所述请求,它发送接受报文(步骤706)并立刻设法得到 移动用户。 If the target IBS accepts the request, it sends an acceptance message (step 706) and try to get the mobile users at once. 当连接被建立(步骤707),目标IBS发送它的输入分组数据到源IBS(步骤708)。 When the connection is established (step 707), the target IBS send its packet data input to the source IBS (step 708). 再参考图4,目标IBS的输入分组数据通过分组I/F 46和作为输入加到选择器电路43。 Referring again to Figure 4, the input packet data destination via the IBS packet I / F 46 and as an input to the selector circuit 43. 在控制单元47的控制下,源IBS比较从编码器/解码器电路42接收到的信道编码信号的质量与分组I/F46接收到的信号的质量(步骤709)。 The quality of the received signal under the control of the control unit 47, compares the received source IBS from the encoder / decoder circuit 42 to the channel encoded signal quality and packet I / F46 (step 709). 来自选择器43的最好质量的信号被选择和输出(步骤710)。 The best quality signal from the selector 43 is selected and output (step 710). 如果被叫用户是公用交换电话网络的固定终端,被选择的最好质量的信号被加到话音编码器43,在这里对该信号进行脉冲编码调制(步骤711和步骤712)并将它经由ISDN线路传送至本地交换机(步骤713)。 If the called subscriber is a public switched telephone network of fixed terminal, the best quality signal is selected is applied to the speech encoder 43, where the signal is a pulse code modulation (step 711 and step 712) and it via ISDN wire transfer to the local switch (step 713). 另一方面,如果被叫用户是别的移动用户,则最好质量的信号未经压缩语音而直接被加到/从PCM转换到分组I/F 46以便经由互联网连接传送(步骤714)。 On the other hand, if the called subscriber is another mobile subscriber, the best quality signal / F 46 is connected via the Internet to transmit (step 714) without being directly applied to compressed speech / converted from PCM to packet I.

当移动用户在目标IBS严格控制之下时,目标IBS将指示源IBS把所有无线电资源交付给其他用户,除了只要存在呼叫就被使用的选择器和接口连接之外。 When the mobile user in the target IBS under strict control, the target source IBS IBS indicating radio resources delivered to all other users, in addition to the call as long as there is selected and used by the interface connections outside.
