实现混合放号的方法及通信网络系统Method and communication network system for realizing mixed number allocation

技术领域technical field

本发明涉及通信技术领域，尤其涉及实现混合放号的方法及通信网络系统。The invention relates to the technical field of communication, in particular to a method for realizing mixed number allocation and a communication network system.

背景技术Background technique

混合放号一般用于在一个本地网范围内实现用户号码的统一管理。拥有混合放号特征后，每个用户将拥有两个号码，一个是向外公布的逻辑号码，一个是决定用户归属地的物理号码。采用这种编号方案后，用户的物理号码可以根据需要跨局迁移，改动，但逻辑号码不变，这样用户即具备了移动的特性。混合放号除了可以在固定用户之间混合放号外，还可以在固定，移动用户间混合放号，实现综合放号的功能。Mixed number allocation is generally used to realize unified management of user numbers within a local network. With the mixed number allocation feature, each user will have two numbers, one is the logical number announced to the public, and the other is the physical number that determines the user's attribution. After adopting this numbering scheme, the user's physical number can be migrated and changed across offices as needed, but the logical number remains unchanged, so that the user has the characteristics of mobility. Mixed number allocation can not only allocate numbers between fixed users, but also between fixed and mobile users to realize the function of comprehensive number allocation.

目前公共电话交换网(PSTN)用户使用的号码与用户实际的端口、设备和网络绑定在一起，用户的位置及归属的端局决定了其使用的号码，使得号码不具有可移动性。At present, the numbers used by users of the public switched telephone network (PSTN) are bound to the actual ports, devices and networks of the users. The location of the users and the end office they belong to determine the numbers they use, making the numbers non-portable.

为了解决号码迁移的问题，提出了号码携带(NP)方案，NP方案一般通过智能网实现，在NP方案中用户拥有两个号码，向外公布使用的逻辑号码和决定其归属地的物理号码。在智能网的NP解决方案中，包括以下两个流程：In order to solve the problem of number migration, a number portability (NP) scheme is proposed. The NP scheme is generally implemented through the intelligent network. In the NP scheme, the user has two numbers, and the logical number used and the physical number that determines its attribution are announced to the outside. In the NP solution of the intelligent network, the following two processes are included:

1、主叫NP业务：将主叫物理号码变换为主叫逻辑号码，用于主叫号码显示和正确的计费。主叫NP业务一般由主叫端局根据用户签约信息将该用户的呼叫自动加插接入码，送到智能网平台，由智能网平台完成主叫号码的变换，然后进行接续。1. Calling NP service: change the calling physical number to the calling logical number, which is used for calling number display and correct billing. For the calling NP service, the calling end office automatically adds an access code to the user's call according to the user's subscription information, and sends it to the intelligent network platform. The intelligent network platform completes the conversion of the calling number and then performs the connection.

2，被叫NP业务：将用户拨打的被叫逻辑号码变换为被叫物理号码，用于对被叫用户的寻址。被叫NP业务一般由被叫端局根据用户签约信息将该用户的呼入加插接入码送到智能网平台，由智能平台完成被叫号码的变换后再进行接续。2. Called NP service: convert the called logical number dialed by the user into the called physical number, which is used to address the called user. The called NP service is generally sent by the called end office to the intelligent network platform according to the user's subscription information, and the called number is converted by the intelligent platform before being connected.

虽然NP方案能实现号码的可移动性，但存在以下问题：Although the NP scheme can realize the portability of numbers, there are the following problems:

1、主叫NP业务存在的问题：目前网上端局交换机种类很多，部分机型不能自动根据用户属性在被叫号码前加插接入码，因此难以在全网实现上述的业务触发，使NP业务受到限制。1. Problems with the calling NP service: There are many types of end-office switches on the network at present, and some models cannot automatically add access codes before the called number according to user attributes. Business is limited.

2、被叫NP业务存在的问题：一方面，存在大量的路由迂回，同时，被叫端局能否支持相应的用户属性及加插相应接入码，将呼叫接续到业务交换点(SSP)也存在不确定的因素。2. Problems in the called NP service: On the one hand, there are a large number of roundabout routes. At the same time, whether the called end office can support the corresponding user attributes and insert the corresponding access code to connect the call to the service switching point (SSP) There are also uncertainties.

3、NP业务只是简单的号码变换流程，而智能网是为处理复杂业务而设计的，使用智能网解决NP业务，将耗费大量的智能网资源。这样，当NP用户容量较多时，对智能网处理能力的冲击较大。3. The NP service is just a simple number change process, while the intelligent network is designed to handle complex services. Using the intelligent network to solve the NP service will consume a lot of intelligent network resources. In this way, when the capacity of NP users is large, the impact on the processing capability of the intelligent network is relatively large.

另外，对于个人手持电话系统(PHS)向3G的迁移，目前的解决方案是PHS用户改号迁移到3G网络。但这种改号迁移方案，不能实现用户不改号无缝迁移到3G网络的功能。In addition, for the migration of the Personal Handyphone System (PHS) to 3G, the current solution is that PHS users change their numbers and migrate to the 3G network. However, this solution for number change and migration cannot realize the function of seamlessly migrating to the 3G network without changing the number of the user.

具体实施方式Detailed ways

参阅图1A所示，在本地网络中建设综合智能归属位置寄存器(SHLR)，该SHLR分别与公共电话交换网(PSTN)、公共陆地移动网(PLMN)、个人手持电话系统(PHS)和第三代网络(3G)连接。SHLR保存用户物理号码和逻辑号码的映射关系、固定移动混合业务的相关数据和集中鉴权数据等。本地网所有的始发呼叫均先发送到SHLR，由SHLR进行主被叫号码的变换，实现混合放号功能。Referring to shown in Fig. 1A, build comprehensive intelligent home location register (SHLR) in local network, this SHLR is connected with public switched telephone network (PSTN), public land mobile network (PLMN), personal handheld telephone system (PHS) and the third party respectively. Next generation network (3G) connection. SHLR saves the mapping relationship between user's physical number and logical number, related data of fixed mobile hybrid service and centralized authentication data, etc. All the originating calls of the local network are first sent to the SHLR, and the SHLR performs the conversion of the calling and called numbers to realize the mixed number allocation function.

参阅图1B所示，SHLR设备通过ISDN用户部分(ISUP)、移动应用部分(MAP)、信令或智能网应用规程(INAP)接口与PSTN网络中的端局LS，长途局TS，汇接局MS，关口局GW，智能SSP局相连，同时与PHS网络中的PHS端局，3G网络中的移动端局VMSC，移动关口局GMSC相连。Referring to Fig. 1B, the SHLR equipment communicates with the end office LS in the PSTN network, the toll office TS, and the tandem office through ISDN user part (ISUP), mobile application part (MAP), signaling or intelligent network application procedure (INAP) interface The MS is connected to the gateway office GW and the intelligent SSP office, and is connected to the PHS end office in the PHS network, the mobile end office VMSC in the 3G network, and the mobile gateway office GMSC.

SHLR实现混合放号业务有基于ISUP信令、基于INAP和基于MAP信令三种方式。There are three ways for SHLR to implement hybrid number allocation services based on ISUP signaling, INAP and MAP signaling.

参阅图2所示，基于ISUP信令的处理过程下：Referring to Figure 2, under the processing process based on ISUP signaling:

a、主叫发呼，呼叫始发交换局通过IAM消息将呼叫发送到SHLR。呼叫始发交换局是指在本地网范围内呼叫的发起局，包括主叫所在端局、长途局、关口局、智能业务交换局(SSP)或代理汇接局(当部分始发交换局不支持时，由汇接局进行代理)等。a. The calling party makes a call, and the call originating exchange sends the call to the SHLR through an IAM message. Call originating switching office refers to the calling originating office within the scope of the local network, including the calling end office, toll office, gateway office, smart service switching office (SSP) or agent tandem office (when part of the originating exchange office does not When it is supported, it will be proxied by the tandem office), etc.

b、SHLR进行主叫号码查询和分析，如果主叫用户是混合放号用户，则将主叫物理号码变换为主叫逻辑号码，通过ACM消息将变换的主叫号码返回；如果主叫不是混合放号用户，不向呼叫始发交换局返回ACM消息。b. SHLR conducts calling number query and analysis. If the calling user is a mixed number allocation user, the calling physical number is converted into the calling logical number, and the converted calling number is returned through the ACM message; if the calling user is not mixed The number allocation user does not return the ACM message to the originating switching office of the call.

c、SHLR进行被叫号码查询和分析，如果被叫用户是混合放号用户，则将被叫逻辑号码变换为被叫物理号码，同时通过回拆重路由消息(REL)将变换的被叫号码返回，并利用REL消息通知端局重新进行号码分析并重现选路；如果被叫不是混合放号用户，REL消息则不返回被叫号码，通知呼叫始发交换局重新选路。c. SHLR performs the called number query and analysis. If the called user is a mixed number allocation user, the called logical number is converted into the called physical number, and the converted called number is converted by returning the rerouting message (REL) Return, and use the REL message to notify the end office to re-analyze the number and re-select the route; if the called party is not a mixed number allocation user, the REL message will not return the called number, and notify the calling originating exchange to re-select the route.

d、呼叫始发交换局收到REL回拆消息后，向SHLR发送释放完成(RLC消息)消息，拆除连接到HLR的中继电路。d. After receiving the REL teardown message, the originating switching office of the call sends a release complete (RLC message) message to the SHLR to tear down the trunk circuit connected to the HLR.

e、呼叫始发交换局根据HLR返回的主被叫号码，重新向被叫号码发起新的呼叫。e. The originating exchange of the call initiates a new call to the called number according to the calling and called numbers returned by the HLR.

f、新的呼叫流程与现有的呼叫流程相同。f. The new call flow is the same as the existing call flow.

参阅图3所示，基于MAP的处理过程如下：Referring to Figure 3, the MAP-based processing is as follows:

a、主叫发呼，呼叫始发交换局向SHLR发起SRI操作。a. The calling party makes a call, and the call originating exchange initiates an SRI operation to the SHLR.

b、SHLR进行主被叫号码查询和分析，如果主叫用户是混合放号用户，则将主叫物理号码变换为主叫逻辑号码；如果被叫用户是混合放号用户，则将被叫逻辑号码变换为被叫物理号码，通过SRIACK消息返回。b. SHLR performs calling and called number query and analysis. If the calling user is a mixed number allocation user, the calling physical number is converted into the calling logic number; if the called user is a mixed number allocation user, the called logical number The number is transformed into the called physical number, which is returned through the SRIACK message.

c、呼叫始发交换局根据SHLR返回的主被叫号码，重新向被叫号码发起新的呼叫。c. The originating exchange of the call initiates a new call to the called number according to the calling and called numbers returned by the SHLR.

d、新的呼叫流程与现有的呼叫流程相同。d. The new call flow is the same as the existing call flow.

参阅图4所示，基于INAP的处理过程如下：Referring to Figure 4, the processing process based on INAP is as follows:

a、对所有本局用户发起的呼叫，触发智能业务，将主被叫号码通过初始监测点(InitialDP)上报给SHLR。a. For calls initiated by all local office users, trigger the intelligent service, and report the calling and called numbers to the SHLR through the initial monitoring point (InitialDP).

b、SHLR配置相应的事件检测点(RRBE)，请求SSP遇到相应的事件监测点上报给SHLR。b. The SHLR configures the corresponding event detection point (RRBE), and requests the SSP to report to the SHLR when encountering the corresponding event detection point.

c、SHLR根据主被叫号码进行业务处理，如果主叫用户是混合放号用户，则将主叫物理号码变换为主叫逻辑号码；如果被叫用户是混合放号用户，则将被叫逻辑号码变换为被叫物理号码；变换后的主被叫号码通过向SSP下发的连接操作(Connect)。c. SHLR performs business processing according to the calling and called numbers. If the calling user is a mixed number allocation user, the calling physical number will be converted into the calling logical number; if the called user is a mixed number allocation user, the called logical number The number is converted into the called physical number; the converted calling and called numbers pass the connection operation (Connect) delivered to the SSP.

d、SSP检测到相应事件后向SHLR上报事件(ERB)。d. After detecting the corresponding event, the SSP reports the event (ERB) to the SHLR.

e、SHLR拆除相应的连接(Releasecall)。e. SHLR removes the corresponding connection (Releasecall).

其中步骤b、d、e中可选消息，如果所有可选消息均不选，则Connect消息必须通过对话结束消息(TC-END消息)下发，以结束对话。Among them, optional messages in steps b, d, and e, if all optional messages are not selected, then the Connect message must be sent through a dialog end message (TC-END message) to end the dialog.

由于在SHLR保存了用户的鉴权数据，SHLR成为集中鉴权中心。在图2、图3和图4的流程中，SHLR进行主被叫分析时，根据鉴权数据和主被叫号码决定是继续呼叫还是终止呼叫，如果是终止呼叫，则通过信令回送给发端局，由发端局拆除此类呼叫。采用集中鉴权不再需要各个网络的关口局根据呼叫的主被叫号码进行判别，克服了因每个网络均要维护一套鉴权数据而存在多点维护和数据复杂的问题。Since the user's authentication data is stored in SHLR, SHLR becomes a centralized authentication center. In the process of Figure 2, Figure 3 and Figure 4, when SHLR analyzes the calling party and called party, it decides whether to continue the call or terminate the call according to the authentication data and the calling and called number. If the call is terminated, it will be sent back to the originating end through signaling The originating office disconnects such calls. The use of centralized authentication no longer requires the gateway office of each network to distinguish according to the calling and called numbers of the call, which overcomes the problems of multi-point maintenance and data complexity because each network needs to maintain a set of authentication data.

由于采用SHLR来实现混合放号，使PHS用户向3G网络的平滑迁移成为可能。由于MSISDN号码(移动台ISDN号码)为国内号码前缀+区号+DN(用户逻辑号码)号码，因此在该用户做主叫时主叫号码的显示将不再存在问题；同时，转网的PHS用户与其他3G用户一样使用WCDMA终端(用户需要更换手机)分配USIM(通用移动通信系统的用户标志模块)卡，IMSI(国际移动用户识别符)号码同其他普通3G用户，因此其他移动网的操作都没有问题。Due to the use of SHLR to realize mixed number allocation, it is possible to smoothly migrate PHS users to 3G networks. Because the MSISDN number (mobile station ISDN number) is the domestic number prefix + area code + DN (subscriber logic number) number, so when the user makes a call, the display of the calling number will no longer have problems; Other 3G users also use WCDMA terminals (users need to change mobile phones) to assign USIM (Universal Mobile Communications System Subscriber Identity Module) cards, and IMSI (International Mobile Subscriber Identity) numbers are the same as other ordinary 3G users, so other mobile network operations are not available question.

参阅图5所示，SHLR与3G网络的归属位置寄存器(HLR)融合。PHS用户转3G网络后在SHLR设置转3G标识。3G网络根据PHS用户原号码，寻址用户的路由信息进行接续。Referring to Fig. 5, the SHLR is integrated with the Home Location Register (HLR) of the 3G network. After the PHS user switches to the 3G network, set the switch to 3G logo on the SHLR. The 3G network addresses the user's routing information for connection according to the original number of the PHS user.

参阅图6所示，PHS用户向3G网络的平滑迁移处理过程如下：As shown in Figure 6, the smooth migration process of PHS users to the 3G network is as follows:

a、本地/外地/他网呼叫该用户时使用其DN号码，就是其原有的固定号码；呼叫被路由到原来的固定本地网。固定本地网交换机(LS/TS/MS/GW)以ISUP信令与SHLR交互查询被叫LRN号码(路由号码)(主叫号码查询略)；a. When local/foreign/other network calls the user, use its DN number, which is its original fixed number; the call is routed to the original fixed local network. The fixed local network switch (LS/TS/MS/GW) interacts with the SHLR to query the called LRN number (routing number) through ISUP signaling (the calling number query is omitted);

b、SHLR查询到被叫LRN号码后进一步分析其转3G网标识，如果该标识表示用户已转3G网络(为“Y”)，则根据其记录的MSC/VLR号向VMSC/VLR发起请求漫游号码(PRN)操作(MAP操作，要求提供MSRN)。b. After the SHLR inquires the called LRN number, it further analyzes its transfer to 3G network identification. If the identification indicates that the user has transferred to the 3G network ("Y"), it initiates a roaming request to the VMSC/VLR according to the MSC/VLR number recorded Number (PRN) operation (MAP operation, MSRN required).

c、被叫用户所在VMSC/VLR分配漫游号码(MSRN)并以PRN ack返回。c. The VMSC/VLR where the called user is located assigns a roaming number (MSRN) and returns it with a PRN ack.

d、综合SHLR将得到的MSRN通过REL消息返回给固网交换机。d. The integrated SHLR returns the obtained MSRN to the fixed network switch through the REL message.

e、固网交换机根据得到的MSRN进行路由重选，将呼叫路由到用户所在VMSC或移动关口局(GMSC)，如果路由到GMSC，GMSC分析该号码为MSRN号码(通过MSRN号段识别)，则不再发起SRI操作，直接分析入局号码路由到VMSC。e. The fixed network exchange performs routing reselection according to the obtained MSRN, and routes the call to the VMSC or the mobile gateway office (GMSC) where the user is located. If the call is routed to the GMSC, the GMSC analyzes that the number is an MSRN number (identified by the MSRN number segment), then The SRI operation is no longer initiated, and the incoming number is directly analyzed and routed to the VMSC.

f、VMSC根据入局MSRN索引到VLR中用户位置更新时由综合SHLR插入的用户数据，并根据其中记录的位置区信息发起寻呼，用户响应后接通呼叫。f. VMSC indexes into VLR the user data inserted by integrated SHLR when the user location is updated according to the incoming MSRN, and initiates paging according to the location area information recorded therein, and connects the call after the user responds.

g、用户挂机后，VMSC呼叫并生成相应的计费信息。g. After the user hangs up, the VMSC calls and generates corresponding billing information.

本发明在网络系统中设置综合智能归属位置寄存器(SHLR)，并在SHLR中建立用户逻辑号码与物理号码的映射关系来实现混合放号功能，使固定用户也可以像移动用户一样跨局迁移，同时使PHS用户能够平滑迁移到3G网络。The present invention sets a comprehensive intelligent home location register (SHLR) in the network system, and establishes the mapping relationship between the user logical number and the physical number in the SHLR to realize the mixed number allocation function, so that fixed users can also migrate across offices like mobile users. At the same time, it enables PHS users to migrate to 3G network smoothly.

在SHLR保存智能业务属性的签约数据、广域集群用户的业务数据、游子归家用户的业务数据、鉴权数据、一机多号或/和一号通业务的业务数据等用户业务数据后，SHLR可以成为全网的简单业务处理中心。该简单业务是指号码变换类业务和业务逻辑简单的业务。After the SHLR saves the subscription data of smart business attributes, the business data of wide-area cluster users, the business data of wandering home users, the authentication data, the business data of one machine with multiple numbers or/and one number service, etc., SHLR can become a simple business processing center of the whole network. The simple service refers to a number change service and a service with simple service logic.

当SHLR作为简单业务中心后，本地网所有的发话呼叫均先到SHLR进行主被叫号码的查询和处理后再接续。SHLR根据智能业务属性的签约数据判断用户签约了智能业务，则直接在用户号码前插入接入码，可以很容易地实现智能业务的全网触发；根据鉴权数据可以对用户进行鉴权，如果鉴权失败则通知终止呼叫；根据广域集群用户的业务数据、游子归家用户的业务数据、一机多号和一号通业务的业务数据可能对主、被叫号码进行转换。因此SHLR成为事实上的数据中心和控制中心。在此基础上，可以发展成全网的简单业务处理中心，集中处理逻辑简单、无交互类的业务。这类业务包括：一号通，游子归家，广域CENTREX的长短号变换，一机多号以及一号多机业务等。When the SHLR is used as a simple service center, all outgoing calls in the local network first go to the SHLR to query and process the calling and called numbers before continuing. SHLR judges that the user has signed up for the smart service based on the subscription data of the smart service attribute, and then inserts the access code directly in front of the user number, which can easily trigger the whole network of the smart service; the user can be authenticated according to the authentication data, if If the authentication fails, the call will be terminated; the calling and called numbers may be converted according to the business data of the wide-area trunking user, the business data of the wandering home user, and the business data of the multi-number and one-number service. So SHLR becomes the de facto data center and control center. On this basis, it can be developed into a simple business processing center of the entire network, which can centrally process services with simple logic and no interaction. This type of business includes: one number connection, wandering home, long and short number change of wide area CENTREX, one phone with multiple numbers and one number with multiple phones, etc.

SHLR可以基于ISUP信令、基于INAP信令和基于MAP信令实现智能业务的全网触发，其基本方法为：SHLR进行主被叫号码分析和查询时，如果主叫签约了智能业务，则在被叫号码前加插主叫智能业务接入码；如果被叫签约了智能业务，也在被叫号码前加插被叫智能业务接入码。然后将变换后的被叫号码回送给发端局，由发端局将呼叫接续到业务交换点(SSP)，由SSP根据智能业务接入码实现业务的接续。SHLR can realize network-wide triggering of intelligent services based on ISUP signaling, INAP signaling and MAP signaling. The basic method is: when SHLR analyzes and inquires calling and called numbers, Add the calling smart service access code before the called number; if the called party subscribes to the smart service, also insert the called smart service access code before the called number. Then the converted called number is returned to the originating office, and the originating office connects the call to the service switching point (SSP), and the SSP realizes the connection of the service according to the intelligent service access code.

参阅图7所示，无混合放号情况下智能业务的触发流程如下(以ISUP为例)：Referring to Figure 7, the triggering process of the intelligent service in the case of no mixed number allocation is as follows (taking ISUP as an example):

a、主叫发起呼叫，本地网始发交换局向SHLR发送IAM，消息中的主叫号码是逻辑号码，被叫号码是逻辑号码。a. The calling party initiates a call, and the originating exchange of the local network sends an IAM to the SHLR. The calling number in the message is a logical number, and the called number is a logical number.

b、当SHLR分析出主叫或者被叫签约了智能业务时，只向呼叫始发交换局回送智能业务接入码。b. When the SHLR analyzes that the calling party or the called party has subscribed to the intelligent service, it only returns the intelligent service access code to the switching office where the call originates.

c、SHLR向呼叫始发交换局发送RLC消息，指示端局拆除与SHLR连接的中继电路。c. The SHLR sends an RLC message to the originating switching office of the call, instructing the end office to remove the trunk circuit connected to the SHLR.

d、呼叫始发交换局向SSP发送IAM消息，IAM中主叫号码为逻辑号码，被叫号码为智能业务接入码+被叫逻辑号码。d. The originating exchange of the call sends an IAM message to the SSP. In the IAM, the calling number is a logical number, and the called number is an intelligent service access code + called logical number.

e、SSP向呼叫始发交换局回送ACM。SSP进入放音收号流程，后续的业务流程与现有流程相同。e. The SSP returns the ACM to the call originating exchange. The SSP enters the process of broadcasting and collecting numbers, and the subsequent business process is the same as the existing process.

参阅图8所示，混合放号情况下智能业务的触发流程如下(以ISUP为例)：Referring to Figure 8, the triggering process of the intelligent service in the case of mixed number allocation is as follows (taking ISUP as an example):

a、主叫发起呼叫，呼叫始发交换局向SHLR发送IAM，消息中的主叫号码是物理号码，被叫号码是逻辑号码。a. The calling party initiates a call, and the originating exchange of the call sends an IAM to the SHLR. The calling number in the message is a physical number, and the called number is a logical number.

b、SHLR根据智能业务属性的签约数据对主被叫号码进行分析，向呼叫始发交换局返回ACM消息，其中返回主叫的逻辑号码。b. The SHLR analyzes the calling and called numbers according to the subscription data of the intelligent service attribute, and returns an ACM message to the switching office where the call originates, including the logic number of the calling party.

c、当SHLR分析出主叫或者被叫签约了智能业务时，只向呼叫始发交换局回送智能业务接入码。c. When the SHLR analyzes that the calling party or the called party has subscribed to the intelligent service, it only returns the intelligent service access code to the call originating exchange.

d、SHLR向呼叫始发交换局发送RLC消息，指示端局拆除与SHLR连接的中继电路。d. The SHLR sends an RLC message to the call originating exchange, instructing the end office to remove the trunk circuit connected to the SHLR.

e、呼叫始发交换局向SSP发送IAM消息，IAM中主叫号码为逻辑号码，被叫号码为智能业务接入码+被叫逻辑号码。e. The originating exchange of the call sends an IAM message to the SSP. In the IAM, the calling number is a logical number, and the called number is an intelligent service access code + called logical number.

f、SSP向端局回送ACM。SSP进入放音收号流程，后续的业务流程与现有流程相同。f. The SSP sends the ACM back to the end office. The SSP enters the process of broadcasting and collecting numbers, and the subsequent business process is the same as the existing process.

参阅图9所示，SHLR基于ISUP信令处理广域集群(CENTREX)业务的流程如下：Referring to Fig. 9, the process of SHLR processing wide-area cluster (CENTREX) business based on ISUP signaling is as follows:

a、主叫发呼，呼叫始发交换局向SHLR发送IAM消息；IAM消息中携带的主被叫信息为：主叫为主叫物理号码，被叫为被叫短号。a. The calling party sends a call, and the originating exchange of the call sends an IAM message to the SHLR; the calling and called information carried in the IAM message is: the calling party is the calling physical number, and the called party is the called short number.

b、SHLR根据主叫物理号码分析主叫用户所在的CENTREX群，获取主叫短号并通过ACM消息返回给呼叫始发交换局。b. SHLR analyzes the CENTREX group where the calling user is located according to the calling physical number, obtains the calling short number and returns it to the originating exchange through an ACM message.

c、SHLR进行被叫号码查询，根据主被叫用户所在的CENTREX群，进行被叫长短号的变换，将出群字冠+被叫长号通过REL消息回送给呼叫始发交换局。c. SHLR conducts the called number query, converts the called long and short numbers according to the CENTREX group where the calling and called users are located, and returns the outgoing group prefix + called long number to the originating switching office of the call through the REL message.

d、呼叫始发交换局收到SHLR发送的REL回拆消息，向SHLR发送RLC消息，拆除与SHLR相连的中继电路。d. The originating switching office of the call receives the REL teardown message sent by the SHLR, sends an RLC message to the SHLR, and removes the trunk circuit connected to the SHLR.

e、呼叫始发交换局根据被叫物理号码向陆地端发送IAM消息，其中主叫号码是主叫短号，被叫号码是被叫长号。e. The originating exchange of the call sends an IAM message to the land terminal according to the called physical number, wherein the calling number is the calling short number, and the called number is the called long number.

f、陆地端局向发端局回送ACM消息。后续的业务流程与现有业务相同。f. The land end office sends back the ACM message to the originating office. The subsequent business process is the same as the existing business.

由于SHLR中保存有用户的鉴权数据，因此SHLR可以作为集中鉴权中心。SHLR进行主被叫分析时，首先根据主、被叫用户的鉴权数据进行鉴权，如果鉴权失败则通过信令指示呼叫始发交换局终止呼叫，由呼叫始发交换局拆除此类呼叫。如果鉴权成功则继续后续处理。现有技术中一般是由各个网络的关口局根据呼叫的主被叫号码进行判别来实现鉴权，因此每个网络均要维护一套鉴权数据，存在多点维护，数据复杂的问题。采用这种集中鉴权方式，只需要在SHLR中维护一套鉴权数据即可。Since the user's authentication data is stored in the SHLR, the SHLR can be used as a centralized authentication center. When SHLR analyzes the calling and called parties, it first performs authentication based on the authentication data of the calling and called users. If the authentication fails, it will instruct the originating exchange to terminate the call through signaling, and the originating exchange will dismantle such calls. . If the authentication is successful, the subsequent processing is continued. In the prior art, authentication is generally implemented by the gateway office of each network according to the calling and called numbers of the call. Therefore, each network needs to maintain a set of authentication data, and there are problems of multi-point maintenance and complex data. With this centralized authentication method, only one set of authentication data needs to be maintained in the SHLR.

同理，如果SHLR根据用户数据判断被叫用户为其他有关号码转换的智能业务用户时，将被叫用户设定的号码返回所述呼叫始发交换局。如一号码业务游子归家等。简要说明如下：Similarly, if the SHLR judges that the called user is an intelligent service user related to number conversion according to the user data, the number set by the called user will be returned to the switching office where the call originates. Such as one number business traveler returning home and so on. A brief description is as follows:

在SHLR保存有用户的一号通业务数据时，当呼叫始发端局将呼叫发送到SHLR后，SHLR查询出一号通用户真实的位置号码，指示呼叫始发交换局按用户真实的位置号码进行接续，其基本流程参阅图10所示。When the SHLR saves the user's ONLY service data, when the originating end office of the call sends the call to the SHLR, the SHLR inquires out the real location number of the ONLY user, and instructs the originating exchange to press the user's real location number To continue, the basic flow is shown in Figure 10.

根据上述，本领域的普通技术可以得知，在SHLR保存有用户的游子归家业务数据(即游子归家用户登记的家庭号码)时，当呼叫始发端局将呼叫发送到SHLR后，SHLR查询出游子归家用户的家庭号码，指示呼叫始发交换局按用户的家庭号码进行接续。在SHLR保存一机多号用户的业务数据(即多个逻辑号码与一个物理号码的对应关系)时，当呼叫始发端局将呼叫发送到SHLR后，SHLR查询出一机多号的物理号码，指示呼叫始发交换局按用户的物理号码进行接续。在SHLR保存一号多机用户的业务数据(即一个逻辑号码对应的多个物理号码)时，当呼叫始发端局将呼叫发送到SHLR后，SHLR查询出一号多机用户对应的多个物理号码，指示呼叫始发交换局按用户的物理号码进行接续。According to the above, it can be known by ordinary technology in the art that when the SHLR stores the user's wandering home service data (that is, the home number registered by the wandering home user), when the originating end office of the call sends the call to the SHLR, the SHLR Query the home number of the home user who is traveling and return home, and instruct the originating switching office to connect the call according to the user's home number. When SHLR saves the service data of one-machine-multiple-number users (that is, the correspondence between multiple logical numbers and one physical number), when the originating end office of the call sends the call to SHLR, SHLR inquires out the physical number of one-machine multiple-number , instructing the originating switching office of the call to connect according to the user's physical number. When SHLR saves the service data of one-number multi-device users (that is, multiple physical numbers corresponding to one logical number), when the originating end office of the call sends the call to SHLR, SHLR inquires out the multiple numbers corresponding to one-number multi-device users. Physical number, instructs the call-originating exchange to proceed with the user's physical number.
