Description

全球微波接入互操作性系统及实现实时、漫游业务的方法 Worldwide interoperability for microwave access system and method for real-time, roaming service

技术领域 FIELD

本发明涉及宽带无线接入网络技术,特别涉及一种全球微波接入互4乘作性系统及实现实时、漫游业务的方法。 The present invention relates to a broadband wireless access network technology, particularly to a method 4 by the world interoperability for microwave access for real-time systems and, roaming service.

背景技术 Background technique

宽带无线接入系统具有频-潜利用率高、辐射小、成本低等特点,因此宽带无线接入技术被业界认为是下一代无线通信的首选技术。 Broadband wireless access system having a frequency - high latent utilization, low radiation, low cost, and therefore broadband wireless access technology was considered a preferred technology for the next generation of wireless communications.

WiMAX (全球微波接入互搡作性),是一种宽带无线接入协议,用于确保不同宽带无线接入设备之间的兼容性和互操作性。 WiMAX (Worldwide Interoperability for Microwave Access for shoving resistance) is a broadband wireless access protocol that ensures compatibility and interoperability between different broadband wireless access equipment. WiMAX网络有两种组网方式:WiMAX网络单独组网或者与现有网络融合组网。 WiMAX network has two modes: a WiMAX network or a separate network integration network and the existing network. 目前比较有前景,且研究得较多的是第二种方式。 Currently more promising and more studied is the second way.

图1为现有技术中典型的WiMAX网络。 FIG. 1 is a typical prior art WiMAX network. 参见图1,该网络采用单独组网的方式,并采用移动IP协议(MIP)提供漫游服务。 Referring to Figure 1, the network uses separate networking manner, and using Mobile IP protocol (MIP) to provide roaming service.

MIP是一种网络层移动性管理协议,它引入了归属代理(HA)、外地代理(FA)两个新的功能实体和隧道技术,在不改变Internet (因特网)路由规则的前提下,解决了移动节点漫游时的路由问题。 MIP is a network layer mobility management protocol, which introduces Home Agent (HA), a foreign agent (FA) two new functional entities and tunneling, without changing the Internet (Internet) routing rules premise to solve the routing problems when roaming mobile node.

如图1所示的网络主要由移动台(MS)、接入服务网络(ASN)、连接服务网络(CSN)和Internet构成。 The network shown in Figure 1 mainly consists of Internet and the mobile station (MS), an access service network (ASN), Connectivity Service Network (CSN). 其中,ASN由基站(ASN-BS )和接入服务网关(ASN-GW)构成,提供802.16的物理层和MAC层功能,同时兼做M1P协议的FA;在该网络中有两个ASN: —个在MS的漫游网络,向MS提供漫游地的Internet接入服务;另一个在MS的归属网络,提供归属地的Internet接入服务。 Wherein, ASN is constituted by the base station (ASN-BS) and an access service gateway (ASN-GW), provides the physical layer and MAC layer functions 802.16, while also offering FA M1P protocol; two ASN in the network: - MS roaming in a network to provide Internet access to roaming services to the MS; MS another in the home network to provide Internet access service in a home. MS支持IP/MIP协议和802,16协议,并通过802.16 空中接口接入基站,基站通过局域网与ASN-GW相连。 MS supports IP / MIP protocol and protocol 802,16, 802.16 air interface access by the base station, connected via LAN to ASN-GW.

上述网络的工作原理是:MS从HA获得归属地址(HoA),当MS从外地代理FA1漫游到外地代理FA2时,从FA2获取转交地址(CoA ),并以该CoA向HA注册,从而绑定MS的Ho A和CoA,在HA与FA或者HA 与MS之间建立隧道,这就是MIP注册过程。 It said network operating principle is: MS obtain a home address (the HoA) from the HA, when the MS roams from the foreign agent to the foreign agent FA1 FA2, the acquired care-of address (CoA) from FA2, and to register the CoA with the HA, thereby binding MS, Ho a and CoA, establish a tunnel between the HA and the FA or the HA and the MS, this is the MIP registration procedure. MS发送数据时,以外地CSN 作为默认路由器直接发送;而由于所有发往MS的IP数据包必须经过MS 归属网络的防火墙过滤,所以MS接收数据要经过三边路由:归属CSN接收发往MS的数据包,并通过MIP隧道转交给外地CSN或ASN,然后再由该外地CSN或ASN转交给MS。 When transmitting data, other than the direct transmission CSN MS as a default router; and destined for the MS because all IP packets must be filtered through a home network firewall MS, the MS receives the data to be routed through the three sides: receiving home CSN sent to the MS packets, and forwarded to the CSN field or MIP tunnel through ASN, CSN and then by the foreign or ASN transferred to MS.

由上述分析可见,现有网络存在以下问题: Seen from the above analysis, the following problems existing networks:

1、 组网方式方面,没有充分利用现有的固定通信网络资源,从而导致网络建设成本高、难度大 1, networking aspects, there is no full use of existing fixed communication network resources, resulting in high cost of network construction, difficult

由于WiMAX网络覆盖范围小,使之不可能单独组建像GSM (全球移动通信系统)那样的广域覆盖网络,因此,需要与现有网络融合组网,特别是与现有的固定通信网络资源融合组网,以降低网络建设成本和难度,而现有技术并没有充分利用现有的固定通信网络资源。 Due to the small WiMAX network coverage, making it impossible to set up a separate like GSM (Global System for Mobile Communications) network such as a wide area coverage, therefore, need to integrate with existing network network, in particular integration with conventional fixed communication network resources networking, in order to reduce network construction costs and difficulty, and the prior art does not make full use of existing fixed communications network resources.

2、 业务能力方面,不能很好地提供实时业务 2, business ability, not well provide real-time business

虽然互联网的兴起使得IP数据业务不断增长,但传统的语音业务在通信业务中占据的比重仍然居于首位,因此,需要提供高质量的实时业务,特别是IP语音服务,而上述网络显然不能保证实时业务的服务质量(QoS)。 Although the rise of the Internet makes IP data traffic is growing, but the proportion of traditional voice services occupy in the communications business is still in the first place, therefore, the need to provide high quality real-time traffic, especially voice over IP services, and above obviously can not guarantee real-time network quality business service (QoS). 虽然现有技术中有通过设置IP专网,即在外地网络的CSN与归属网络的CSN之间建立IP语音(VoIP)专线,来获得具有电信级QoS的VoIP网络系统,但建设VoIP专线需要投入较大的建设资金和运行费用。 Although by setting the IP private network that is established between CSN CSN foreign network and the home network voice over IP (VoIP) line, to get the VoIP network system with carrier-class QoS, but the construction of Line VoIP need to invest in the prior art large construction capital and operating costs.

3、 漫游服务方面,只能通过三边路由来实现 3, roaming services, can only be achieved through a three-wing Origin

多个电信运营商不能通过用户漫游共享网络,而WiMAX网络覆盖范围又比较小,依靠三边路由实现的漫游服务不能保证实时业务的QoS,只能在有限的覆盖范围内提供对实时性要求不高的数据业务。 Number of telecommunications carriers can not be shared by users roaming network, and WiMAX network coverage and relatively small, rely on three sides roaming service does not guarantee QoS routing to achieve real-time business, not only provide real-time requirements within limited coverage high data traffic.

图4是本发明采用图2所示的网络系统,实现IP语音业务的上行语音处理 FIG 4 is a network system of the present invention is shown in Figure 2, to achieve an uplink voice over IP service voice processing

过程示意图。 Schematic diagram. 参见图4, i步骤401: ASN将用户数据包发送给CSN; Referring to Figure 4, i Step 401: ASN sends the user data packet to the CSN;

本步骤中,MS将用户数据包(包括HoA和用户的数据),通过802.16接入基站;基站完成用户数据的汇聚子层(CS)处理,然后将IP包通过ASN的内部数据通道(DP)发送给ASN-GW; ASN-GW将IP包加上通用路由封装(GRE),成为CoAIP包,发送给CSN。 In this step, the MS user data packet (including the HoA and the user data), by the access base station 802.16; completion station user data convergence sublayer (CS) processing, then the IP packet through the ASN internal data path (DP) sent to the ASN-GW; ASN-GW IP packet plus the generic routing encapsulation (the GRE), become CoAIP packet sent to CSN.

步骤402: CSN将CoAIP包还原为IP包,并从中分离出语音包; Step 402: CSN CoAIP the packet is reduced to an IP packet, and separates the voice packet;

语音、数据和信令在空中接口的物理层分别放在不同的信道之中传输,但是,在经过ASN到CSN的地面传输线路时,混合在同一条传输线路中传输, 例如,在本实施例中,通过LAN统一封装在IP包里传输; Voice, data and signaling are placed among the different transport channels in the physical layer air interface, however, when the ASN to the CSN via terrestrial transmission lines, hybrid transmission in the same transmission line, e.g., in the embodiment of the present , the transmission through the LAN IP unified package bag;

ASN和CSN都具有从IP包中将逻辑信道还原的能力,例如,通过物理分离的方式,为数据业务处理板配置一个IP地址,为语音业务处理板配置另一个1P地址,这样,语音和数据就很容易分开; ASN and CSN have the ability to reduce the IP packet in the logical channels from, e.g., by way of physical separation, configure an IP address for the data service processing board, 1P address to configure another voice processing board, so that voice and data it is easy to separate;

而CSN分离语音、数据和信令的方法是根据无线信道的不同来区分的,例如,MS在发送语音或数据的时候,就自动分配到不同类型的物理信道,基站接收的时候,也按照不同的无线信道类型,直接就将语音和数据区別开。 The method of separating the CSN voice, data and signaling radio channel are different to distinguish between, for example, when the MS transmits voice or data, is automatically allocated to different types of physical channels, the base station receives the time, also according to different the radio channel type, will direct the voice and data distinguished.

步骤403: AN将IP包中的净荷解出后,还原成64kbit/s的PCM语音,放到E1的时隙通道上,通过V5.2协议,传给LE。 Step 403: After the AN IP packet payload solved, restore the PCM speech 64kbit / s, the channel time slot into E1 by protocol V5.2, passed LE.

步骤404: LE将64kbit/s的PCM语音发送至PSTN、 PLMN等电路交换网络,并最终到达对方MS。 Step 404: LE to PCM voice 64kbit / s is transmitted to the PSTN, PLMN, circuit switching networks, and finally to the other MS.

至此,上行语音处理过程结束,下行语音处理是上行语音处理的逆过程, 下面对下行语音处理过程进行说明。 Thus, the uplink speech processing ends, the downlink is the reverse of speech processing uplink speech processing, speech processing procedure Next, the downlink will be described. 图5是本发明采用图2所示的网络系统, 实现IP语音业务的下行语音处理过程示意图,.参见图5,该过程包括以下步骤: FIG 5 is a diagram of a network system of the present invention is employed in FIG. 2, a schematic diagram of a downlink speech processing procedure implemented voice over IP services, see FIG. 5, the process comprising the steps of:

步骤501: LE从PSTN 、 PLMN等电路交换网络接收到发给本网MS的64kbit/s的PCM语音。 Step 501: LE received from the PSTN, PLMN, circuit switching network to the PCM voice is sent to this site MS 64kbit / s of.

步骤502: LE将该语音放到El的时隙通道上,通过V5.2协议传送给AN。 Step 502: LE placed on the voice channel slots El and transmitted to the AN through the V5.2 protocol.

步骤503: AN将64kbit/s的PCM语音转换成IP语音包,发送给CSN。 Step 503: AN the PCM voice 64kbit / s into IP voice packets, sent to the CSN.

步骤504: CSN将用户数据发送给ASN; Step 504: CSN user data to the ASN;

ASN-GW将CoA IP包解封装,并通过ASN的内部数据通道(DP )发iil给基站;基站通过802.16将数据发送给MS。 The ASN-GW CoA IP packets decapsulated and sent to the base station via the ASN iil internal data paths (the DP); the base station transmits data to the MS through 802.16. 至此,下行语音处理过程结束。 At this point, the downstream end of the voice processing.

另外,当用户关机时,可以主动发Detach;但离开网络覆盖区域时,不会主动发Detach,这样就会造成寻呼失败。 Further, when the user turned off, can actively send the Detach; but leaves the coverage area of ​​the network, does not send the Detach active, this will result in paging failure. 本方案中,当寻呼失败连续超过一定次数,如3次时,由ASN-GW通知LE将该MS从寻呼区域删除,以提高效率。 In the present embodiment, when the paging failed continuously for more than a certain number of times, such as when three times the ASN-GW notifies the MS LE removed from the paging area, to improve efficiency.

以上是对本发明提供IP语音业务的具体实施方法的说明,该方法通过在原有WiMAX网络基础上,设置由CSN到AN再到LE的通道,并由CSN 将语音业务从用户数据中分离之后,传送到该通道进行处理,在WiMAX网络中实现了IP语音业务;并且,由于该通道采用电路交换实现语音传输, 因而具有优质的QoS,实现了在宽带无线接入网中提供电信级TP语音服务的目的。 To provide a voice service over IP of the present invention, illustrate specific embodiments of the method, the method based on the existing WiMAX network, and then set the channel from the LE to the AN CSN, followed by separation of the voice service from the CSN user data, transfer to the channel processing, voice over IP services in a WiMAX network; and, since the circuit-switched voice channel transmission, which has the QoS quality achieved TP provide carrier-class voice in a broadband wireless access network and services purpose.

此外,在上述实施例中,漫游MS用户的数据业务仍然通过MIP的三边路由提供,而用户的语音业务则通过CSN分离之后,传送至由CSN、 AN 和LE组成的通道进行处理,如此,为语音业务提供了一种新的漫游方式, 实现了数据业务与实时业务分别漫游;并且通过网间漫游拓展了覆盖范围, 弥补了802.16在覆盖方面的不足,使运营商能够迅速开展服务. Further, in the above embodiment, the user data services roaming MS is still provided by the MIP triangular routing, and after the user voice service separated by the CSN, is transmitted to the channel by the CSN, consisting of the AN and LE is processed, so, provide for voice roaming services, a new way to achieve real-time data services and roaming services separately; and expand coverage through inter-network roaming, to make up for deficiencies in the coverage of 802.16, allowing operators to rapidly initiate service.
