技术领域technical field
本发明涉及一种使用闭合用户群业务的实现方法，特别是指一种在主、被叫用户进行通话呼叫时，将主叫用户和/或被叫用户的闭合用户群(CUG)编码信息记录到相应的话单中，并由主叫用户和/或被叫用户的CUG编码信息由计费中心在计费操作时提取并给予相应资费优惠的处理方法。属于数据通信技术领域。The present invention relates to a method for realizing closed user group services, in particular to recording the closed user group (CUG) coding information of the calling user and/or the called user when the calling user and the called user make a call. Into the corresponding bill, and the CUG coded information of the calling user and/or the called user is extracted by the billing center during the billing operation and given a corresponding tariff discount. It belongs to the technical field of data communication.
背景技术Background technique
对集团用户给予特殊优惠的资费政策，给集团用户和运营商都带来了利益，使得集团用户发展非常迅速。但是由于资费上的技术问题，使得这一业务开展的普及程度受到限制。The special preferential tariff policy for group users has brought benefits to both group users and operators, making group users develop very rapidly. However, due to technical problems in tariffs, the popularity of this service is limited.
目前利用现有技术实现集团用户资费优惠的方式大致有两种：At present, there are roughly two ways to use existing technologies to realize preferential tariffs for group users:
一，使用统一的集团用户编号方案，由运营商的计费中心(Bill Server，简称：BS)根据用户的号码在结算时进行后处理；使用统一的集团用户编号方案，计费中心需要在处理计费详单时判断主叫、被叫、计费方等的号码，对属于某集团的用户在集团内费率做特殊的优惠。具体需要将集团用户加入统一数据库，在批价时，对于主叫、被叫、前转话单中的主叫号码、被叫号码、前转号码进行分析，如果是网内用户(号码在同一集团号段内)，则给予呼叫中的主被叫用户以话费优惠。非同一集团号段的用户，则按普通费率扣费。1. Using a unified group user numbering scheme, the operator's billing center (Bill Server, BS for short) performs post-processing according to the user's number during settlement; using a unified group user numbering scheme, the billing center needs to process Judging the numbers of the calling party, called party, billing party, etc. when billing details, and giving special discounts to users belonging to a certain group within the group. Specifically, it is necessary to add group users to the unified database. When approving prices, analyze the calling number, called number, and forwarding number in the calling list, called number, and forwarding number. within the group number range), the caller and called party during the call will be given a discount on the call fee. Users who are not in the same group number segment will be charged at the normal rate.
这种方式的缺点是：由于计费中心通常与集团处于同一地域，其只能对业务给予优惠计费，而集团用户的漫游业务则由于参与统计的计费中心不同，集团用户实际上并不能得到相应的优惠；因此，如果要在全国实现某一集团的集群业务，上述的方法则无法实现相应的优惠计费。The disadvantage of this method is: since the billing center is usually in the same area as the group, it can only give preferential billing to the business, while the roaming business of the group users is actually not available to the group users due to the different billing centers participating in the statistics. Get the corresponding discount; therefore, if you want to realize the cluster business of a certain group in the whole country, the above method cannot realize the corresponding preferential billing.
其二，采用智能MVPN(虚拟专用移动网，Mobile Virtual Private Network)触发方式实现集团用户的费率优惠：集团用户每次始发或接收呼叫时，移动交换中心(Mobile Switch Center，简称：MSC)都触发智能MVPN流程到服务控制点(Service Control Point，简称：SCP)，SCP记录了集团用户的帐户信息，因而可以由它来判断该呼叫是网内还是网外呼叫，并由计费中心配合，对集团内呼叫给予话费优惠。Second, the smart MVPN (Mobile Virtual Private Network, Mobile Virtual Private Network) trigger method is used to realize the preferential rate for group users: each time a group user initiates or receives a call, the mobile switching center (Mobile Switch Center, referred to as: MSC) Both trigger the intelligent MVPN process to the service control point (Service Control Point, referred to as: SCP), and the SCP records the account information of the group user, so it can be used to judge whether the call is on-net or off-net, and the billing center will cooperate , give discounts on calls within the group.
上述的计费方案需要运营网络的MSC网元具有智能能力；而由智能设备参与的呼叫接续速度相对较慢；智能MVPN方案占用MSC/SSP(业务交换点，Service Switch Point，简称SSP)和SCP之间的信令资源，同时，SCP的处理能力也可能成为此方案的处理瓶颈，因而，从一定程度影响了集团用户数量的发展；由于流程上的限制，目前MVPN跟PPS(预付费业务，Pre-Paid Service)不能同时签约，因此对于预付费用户而言，还无法加入MVPN集团，享受话费的优惠。The above billing scheme requires the MSC network element of the operating network to have intelligent capabilities; while the call connection speed participated by intelligent devices is relatively slow; the intelligent MVPN scheme occupies MSC/SSP (Service Switch Point, SSP for short) and SCP At the same time, the processing capacity of SCP may also become the processing bottleneck of this solution, thus affecting the development of the number of group users to a certain extent; due to the limitation of the process, currently MVPN and PPS (prepaid service, Pre-Paid Service) cannot be signed at the same time, so for pre-paid users, it is still not possible to join the MVPN group and enjoy the discount on call charges.
在3GPP(The 3rd Generation Partnership Project，第三代伙伴关系计划)TS(技术规范，Technical Specification)中定义有闭合用户群(C1osed User Group，简称：CUG)业务，该CUG(闭合用户群)业务是一种GSM phase2(GSM第二阶段)定义的补充业务。它面向的对象是集团用户或者特殊人群，例如：公司或者亲友族。闭合用户群提供用户跟本网或网间其他用户组成闭合群的功能，对群外的访问进行限制。在某个CUG内部，用户之间可以正常进行呼叫，但不能接收群外呼叫和发起到群外的呼叫(具有OA/IA，出群/入群接入能力权限除外)。CUG补充业务不影响紧急呼叫。一个用户可以同时属于一个或多个CUG，最多不能超过10个。这些CUG通过CUG索引来区分，索引由运营商提供和分配。但是，3GPP TS没有定义它的计费过程，因而，CUG一直没有得到很好的利用。In 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) TS (Technical Specification, Technical Specification), there is a closed user group (C1osed User Group, referred to as: CUG) service, the CUG (closed user group) service is A supplementary service defined by GSM phase2 (GSM phase 2). It is aimed at group users or special groups of people, such as companies or relatives and friends. The closed user group provides users with the function of forming a closed group with other users on the network or in the network, and restricts access outside the group. Within a certain CUG, users can normally make calls between users, but cannot receive or initiate calls outside the group (except for OA/IA, group-out/group-in access capabilities). CUG supplementary services do not affect emergency calls. A user can belong to one or more CUGs at the same time, up to 10. These CUGs are distinguished by a CUG index, which is provided and allocated by the operator. However, 3GPP TS does not define its charging process, therefore, CUG has not been well utilized.
发明内容Contents of the invention
本发明所要解决的主要技术问题是提供一种基于CUG业务实现集团用户优惠资费的计费方案，能够针对不同类型、不同地区的用户提供全网资费优惠，可以为集团用户提供包括漫游业务在内的优惠计费方法，同时避免采用智能设备而带来的呼叫接续速度较慢、占用信令资源以及SSP/SCP处理瓶颈等问题。The main technical problem to be solved by the present invention is to provide a billing scheme based on the CUG service to realize preferential tariffs for group users, which can provide preferential tariffs for the entire network for users of different types and regions, and can provide group users with roaming services. At the same time, it avoids problems such as slow call connection speed, occupation of signaling resources, and SSP/SCP processing bottlenecks caused by the use of smart devices.
本发明具体通过如下的技术方案解决了上述技术问题：The present invention specifically solves the above-mentioned technical problems through the following technical solutions:
一种实现集团用户优惠资费的处理方法，在主叫用户和被叫用户进行通话呼叫时，将主叫用户和/或被叫用户的CUG编码信息记录到相应的话单中，该主叫用户和/或被叫用户的CUG编码信息由计费中心在计费操作时提取，并根据相应的资费优惠规则计算得到集团用户优惠的费用数据。A processing method for realizing preferential tariffs for group users. When the calling user and the called user make a call, the CUG code information of the calling user and/or the called user is recorded in the corresponding bill, and the calling user and the called user /or the CUG code information of the called user is extracted by the billing center during the billing operation, and calculated according to the corresponding preferential tariff rules to obtain the group user preferential fee data.
本发明通过采用CUG，避免了采用智能设备而带来的呼叫接续速度较慢、占用信令资源以及SSP/SCP处理瓶颈等问题，并且具有如下的优点：By adopting the CUG, the present invention avoids problems such as slow call connection speed, occupation of signaling resources, and SSP/SCP processing bottleneck caused by the use of smart devices, and has the following advantages:
采用CUG实现了不同类别的用户虚拟在一个集团用户群内，从而避免了预付费用户更换手机号码，给用户和运营商带来了便利，也丰富了预付费用户的业务。Using CUG enables different types of users to be virtualized in a group user group, thereby avoiding the need for prepaid users to change mobile phone numbers, bringing convenience to users and operators, and enriching the services of prepaid users.
CUG不需要手机支持也可以实现，所以在终端方面没有限制；用户漫游时也能得到优惠的资费，实现了国际、国内，网内、网间范围内的集团业务。CUG can be implemented without the support of mobile phones, so there is no limitation in terms of terminals; users can also get preferential tariffs when roaming, realizing international, domestic, intra-network, and inter-network group services.
CUG本身是GSM已经定义了的补充业务，现有网上的设备就能提供这样的功能，只需要小小的改动，就可以实现丰富多样的计费策略。CUG itself is a supplementary service already defined by GSM. Existing devices on the network can provide such a function, and various billing strategies can be implemented with only minor changes.
具体实施方式Detailed ways
以下结合具体的实施例对本发明作进一步的详细说明：Below in conjunction with specific embodiment the present invention is described in further detail:
在计费规范中，一般必选的话单有主叫话单(MOC)，被叫话单(MTC)和前转话单(CFW)。由于CUG这种补充业务一般适用于语音呼叫，数据业务和传真业务，所以在这三种话单中(MOC、MTC、CFW)，与用户直接相关的话单中需要提供充分的CUG信息，以便计费中心(Bill Server，简称：BS)批价时根据话单中记录的集团用户标记，区别对待网内网外的呼叫。In the billing specification, the generally required bills include the calling bill (MOC), the called bill (MTC) and the forwarding bill (CFW). Since the supplementary service CUG is generally applicable to voice calls, data services and fax services, in these three bills (MOC, MTC, CFW), it is necessary to provide sufficient CUG information in the bills directly related to users, so as to calculate The bill server (Bill Server, referred to as: BS) treats the calls in and out of the network differently according to the group user mark recorded in the bill when approving the price.
首先，要通过CUG业务实现集团用户资费优惠，需要在MSC的计费详单的主叫话单(MOC)、前转话单(CFW)、被叫话单(MTC)中各自增加：First of all, to realize group user tariff discounts through the CUG service, it is necessary to add each in the calling bill (MOC), forwarding bill (CFW), and called bill (MTC) of the billing bill of MSC:
1)用于标识主叫用户CUG编码的字段(CallerCUGInterlockCode)；1) A field (CallerCUGInterlockCode) for identifying the CUG code of the calling user;
2)用于标识被叫用户CUG编码的字段(CalledCUGInterlockCode)。2) A field for identifying the CUG code of the called user (CalledCUGInterlockCode).
上述的CUG编码的字段为是两个字节的整数数字，例如：1234。运营商可以在全网中进行规划，也可以在其各个子网中进行规划。The above-mentioned CUG encoded field is an integer number of two bytes, for example: 1234. Operators can plan in the entire network or in each subnet.
另外引入了CUG计费流程，完全兼容以前的非CUG计费处理，以下分别以8个实施例，从呼叫流程和计费分拣的角度，对本发明作进一步的说明：In addition, the CUG billing process is introduced, which is fully compatible with the previous non-CUG billing process. The following 8 embodiments are used to further illustrate the present invention from the perspective of call process and billing sorting:
实施例1，移动用户-移动用户的出局呼叫，其CUG群内呼叫流程及其详单填写的过程如下：Embodiment 1, mobile user-mobile user's outbound call, the call flow in the CUG group and the process of filling in the detailed list are as follows:
以主叫用户(CUG群1用户)呼叫被叫用户(CUG群1用户)为例的CUG群内呼叫的呼叫过程：The call process of a call within a CUG group, taking the calling user (CUG group 1 user) calling the called user (CUG group 1 user) as an example:
首先确定：First make sure:
主叫用户只签约了一个CUG群，且该CUG群的CUG群码(CUGInterlock)＝1，对应该CUG群的用户索引(CUGIndex)＝11；The calling user only subscribes to one CUG group, and the CUG group code (CUGInterlock) of the CUG group=1, and the user index (CUGIndex) of the corresponding CUG group=11;
被叫用户只签约了一个CUG群，且该CUG群的CUGInterlock＝1，对应该CUG群的用户CUGIndex＝22；The called user only subscribes to one CUG group, and the CUGInterlock of the CUG group=1, corresponding to the user CUGIndex of the CUG group=22;
如果主叫用户是CUG用户，手机在发送呼叫建立setup(初始呼叫建立消息)消息时，可以带上该主叫用户的用户索引；If the calling user is a CUG user, the mobile phone can carry the user index of the calling user when sending the call setup setup (initial call setup message) message;
发端MSC/VLR根据主叫用户的签约数据向位置归属寄存器(HomeLocation Register，简称HLR)发送路由信息，带上主叫用户的CUG群码以及该用户的CUG出群能力信息；The originating MSC/VLR sends routing information to the HomeLocation Register (HLR) according to the calling user's subscription data, and carries the calling user's CUG group code and the user's CUG outgoing group capability information;
HLR查询被叫用户的信息，根据被叫用户的CUG群码进行CUG原则匹配，发现主、被叫是同群用户，因此接受呼叫，向发端MSC/访问地位置寄存器(Visit Location Register，简称VLR)发送被叫用户路由信息MSRN(Mobile Station Roaming Number移动台漫游号码)的同时，带上被叫用户的CUG群码和CUG出群能力信息；HLR queries the information of the called user, performs CUG principle matching according to the CUG group code of the called user, and finds that the calling party and the called party are users in the same group, so accepting the call, and sending the call to the originating MSC/Visit Location Register (VLR for short) ) while sending the called user routing information MSRN (Mobile Station Roaming Number mobile station roaming number), bring the called user's CUG group code and CUG out-group capability information;
发端MSC/VLR收到路由信息响应，发现SRI-ACK中带有CUG群码和CUG出群能力信息，就直接记录下来。最终出计费详单MOC时，将主叫用户的CUG群码记录在MOC的CallerCUGInterlockCode字段、被叫用户的CUG群码记录在CalledCUGInterlockCode中；The originating MSC/VLR receives the routing information response, finds that the SRI-ACK contains the CUG group code and the CUG outgoing capability information, and records it directly. When MOC is finally issued, record the CUG group code of the calling user in the CallerCUGInterlockCode field of the MOC, and record the CUG group code of the called user in CalledCUGInterlockCode;
呼叫接续，发端MSC向收端MSC发送IAM(Initial Address Message，初始地址消息，ISUP的第一条信令)消息，带上主叫用户的CUG群码和CUG出群能力信息；Call connection, the originating MSC sends an IAM (Initial Address Message, initial address message, the first signaling of ISUP) message to the receiving MSC, carrying the calling user's CUG group code and CUG outgoing group capability information;
收端MSC在收到IAM消息后，记录下主叫用户的CUG群码，以便最终产生MTC时，记录在MTC的CallerCUGInterlockCode字段中；另一方面，接续过程中获取被叫用户数据的同时，收端MSC会得到被叫用户的CUG群码，最终会记录在MTC话单的CalledCUGInterlockCode中；After receiving the IAM message, the MSC at the receiving end records the CUG group code of the calling user, so that when the MTC is finally generated, it is recorded in the CallerCUGInterlockCode field of the MTC; The terminal MSC will get the CUG group code of the called user, which will eventually be recorded in the CalledCUGInterlockCode of the MTC bill;
计费中心在收到发端MSC的MOC话单后，比较CallerCUGInterlockCode字段和CalledCUGInterlockCode字段的信息，如果一致(都为1)，则认为主、被叫用户为CUG同群用户，就给予主叫用户该群相应的资费优惠。相应的，计费中心在收到收端MSC的MTC话单后，比较CallerCUGInterlockCode字段和CalledCUGInterlockCode字段的信息，如果一致(都为1)，则认为主、被叫用户为CUG同群用户，就给予被叫用户该群相应的资费优惠。After receiving the MOC bill from the originating MSC, the billing center compares the information in the CallerCUGInterlockCode field and the CalledCUGInterlockCode field. If they are consistent (both are 1), the calling user and the called user are considered to be CUG users in the same group, and the calling user is given the Group corresponding tariff discounts. Correspondingly, after receiving the MTC bill from the MSC at the receiving end, the billing center compares the information in the CallerCUGInterlockCode field and the CalledCUGInterlockCode field, and if they are consistent (both are 1), then the calling user and the called user are considered to be CUG users in the same group, and the The corresponding tariff discount for the called user group.
实施例2，移动用户-移动用户的出局呼叫，其CUG群间呼叫流程及其详单填写的过程如下：Embodiment 2, mobile user-mobile user's outbound call, its CUG inter-group call flow and the process of filling in the detailed list are as follows:
以主叫用户(CUG群1用户)呼叫被叫用户(CUG群2用户)为例，说明CUG群间呼叫的呼叫过程：Take the calling user (CUG group 1 user) calling the called user (CUG group 2 user) as an example to illustrate the call process between CUG groups:
主叫用户：只签约了一个CUG群，且该CUG群的CUGInterlock＝1，对应该CUG群的用户CUGIndex＝11，且CUG-OA(CUG出群能力)为yes(可以出群)；Calling user: only subscribed to one CUG group, and the CUGInterlock of the CUG group=1, the corresponding user CUGIndex of the CUG group=11, and the CUG-OA (CUG group exit ability) is yes (can exit the group);
被叫用户：只签约了一个CUG群，且该CUG群的CUGInterlock＝2，对应该CUG群的用户CUGIndex＝22，且CUG-IA(CUG入群能力)为yes(可以入群)；Called user: only subscribed to one CUG group, and the CUGInterlock of the CUG group=2, corresponding to the user CUGIndex of the CUG group=22, and CUG-IA (CUG group entry ability) is yes (can join the group);
如果主叫用户是CUG用户，手机在发送呼叫建立setup消息时，可以带上该主叫用户的用户索引；If the calling user is a CUG user, the mobile phone can carry the user index of the calling user when sending a call setup message;
发端MSC/VLR根据主叫用户的签约数据向HLR发送路由信息，带上主叫用户的CUG群码以及该用户的CUG出群能力信息；The originating MSC/VLR sends routing information to the HLR according to the calling user's subscription data, and carries the calling user's CUG group code and the user's CUG out-group capability information;
HLR查询被叫用户的信息，根据被叫用户的CUG群码进行CUG原则匹配，发现主、被叫用户不是同群用户，因此检查主叫用户的CUG-OA和被叫用户的CUG-IA，发现可以接受呼叫，就向发端MSC/VLR发送被叫用户路由信息MSRN的同时，带上被叫用户的CUG群码和CUG出群能力信息；HLR queries the information of the called user, performs CUG matching according to the CUG group code of the called user, and finds that the calling user and the called user are not in the same group, so check the CUG-OA of the calling user and the CUG-IA of the called user, When it is found that the call can be accepted, it sends the called user's routing information MSRN to the originating MSC/VLR, and at the same time carries the called user's CUG group code and CUG group outgoing capability information;
发端MSC/VLR收到路由信息响应，发现发路由信息(Send Routing Info，简称SRI)-ACK(请给出中英文全称)中带有CUG群码和CUG出群能力信息，就直接记录下来。最终出计费详单MOC时，将主叫用户的CUG群码记录在MOC的CallerCUGInterlockCode字段；被叫用户的CUG群码记录在CalledCUGInterlockCod中；The originating MSC/VLR receives the routing information response and finds that the Send Routing Info (SRI for short)-ACK (please give the full name in Chinese and English) contains CUG group code and CUG outgoing group capability information, and records it directly. When the MOC is finally issued, the CUG group code of the calling user is recorded in the CallerCUGInterlockCode field of the MOC; the CUG group code of the called user is recorded in CalledCUGInterlockCod;
呼叫接续，发端MSC向收端MSC发送IAM消息，带上主叫用户的CUG群码和CUG出群能力信息；When the call is connected, the originating MSC sends an IAM message to the receiving MSC, carrying the calling user's CUG group code and CUG outgoing group capability information;
收端MSC在收到IAM消息后，记录下主叫用户的CUG群码，以便最终产生MTC时，记录在MTC的CallerCUGInterlockCode字段中；另一方面，接续过程中获取被叫用户数据的同时，收端MSC会得到被叫用户的CUG群码，最终会记录在MTC话单的CalledCUGInterlockCode中；After receiving the IAM message, the MSC at the receiving end records the CUG group code of the calling user, so that when the MTC is finally generated, it is recorded in the CallerCUGInterlockCode field of the MTC; The terminal MSC will get the CUG group code of the called user, which will eventually be recorded in the CalledCUGInterlockCode of the MTC bill;
计费中心在收到发端MSC的MOC话单后，比较CallerCUGInterlockCode字段和CalledCUGInterlockCode字段的信息，不一致，则认为主、被叫用户为非CUG同群用户，但可以根据不同集团用户间的呼叫优惠政策给予主叫用户相应的资费优惠。相应的，计费中心在收到收端MSC的MTC话单后，比较CallerCUGInterlockCode字段和CalledCUGInterlockCode字段的信息，不一致，则认为主、被叫用户非CUG同群用户，但可以根据不同集团用户间的呼叫优惠政策给予被叫用户相应的资费优惠。After receiving the MOC bill of the originating MSC, the billing center compares the information in the CallerCUGInterlockCode field with the CalledCUGInterlockCode field. If they are inconsistent, the calling user and the called user are considered to be non-CUG group users. Give the calling user a corresponding tariff discount. Correspondingly, after receiving the MTC bill from the MSC at the receiving end, the billing center compares the information in the CallerCUGInterlockCode field with the CalledCUGInterlockCode field. The call preferential policy gives the called user the corresponding preferential tariff.
实施例3，移动主叫用户-移动被叫用户-无条件前转到另一移动用户，CUG群内呼叫流程及其详单填写的过程如下：Embodiment 3, mobile calling user-mobile called user-forwarding to another mobile user unconditionally, the call flow in the CUG group and the process of filling in the detailed form are as follows:
以第一移动用户(CUG群1用户)呼叫第二移动用户(CUG群1用户)无条件前转到第三移动用户(CUG群1用户)为例，以下说明了前转情况下CUG群内呼叫的呼叫过程：Taking the first mobile user (CUG group 1 user) to call the second mobile user (CUG group 1 user) unconditionally forwarded to the third mobile user (CUG group 1 user) as an example, the following describes the call in the CUG group in the case of forwarding The calling process:
第一移动用户只签约了一个CUG群，且该CUG群的CUGInterlock＝1，对应该CUG群的用户CUGIndex＝11；The first mobile user only subscribes to one CUG group, and the CUGInterlock of the CUG group=1, corresponding to the user CUGIndex of the CUG group=11;
第二移动用户：只签约了一个CUG群，且该CUG群的CUGInterlock＝1，对应该CUG群的用户CUGIndex＝22；The second mobile user: only subscribed to one CUG group, and the CUGInterlock of the CUG group=1, corresponding to the user CUGIndex of the CUG group=22;
第三移动用户：只签约了一个CUG群，且该CUG群的CUGInterlock＝1，对应该CUG群的用户CUGIndex＝33；The third mobile user: only subscribed to one CUG group, and the CUGInterlock of the CUG group=1, corresponding to the user CUGIndex of the CUG group=33;
流程说明：Flow Description:
如果第一移动用户是CUG用户，手机在发送呼叫建立setup消息时，可以带上该第一移动用户的用户索引；If the first mobile user is a CUG user, the mobile phone may carry the user index of the first mobile user when sending the call setup setup message;
发端MSC/VLR根据第一移动用户的签约数据向HLR发送路由信息，带上第一移动用户的CUG群码以及该第一移动用户的CUG出群能力信息；The originating MSC/VLR sends routing information to the HLR according to the subscription data of the first mobile user, and carries the CUG group code of the first mobile user and the CUG group outgoing capability information of the first mobile user;
HLR查询第二移动用户的信息，根据第二移动用户的CUG群码进行CUG原则匹配，发现第一、二移动用户是同群用户，因此接受呼叫，再查第二移动用户数据，发现该第二移动用户无条件前转到第三移动用户，就向发端MSC/VLR发送被第三移动用户FTN(第三移动用户的号码)的同时，带上第二移动用户的CUG群码和CUG出群能力信息；HLR queries the information of the second mobile user, performs CUG principle matching according to the CUG group code of the second mobile user, and finds that the first and second mobile users are users in the same group, so accepts the call, and then checks the data of the second mobile user, and finds that the first mobile user is in the same group. The second mobile user forwards to the third mobile user unconditionally, and sends the third mobile user's FTN (the third mobile user's number) to the originating MSC/VLR while carrying the second mobile user's CUG group code and CUG out of the group capability information;
发端MSC/VLR收到路由信息响应，发现SRI-ACK中带有CUG群码和CUG出群能力信息，就直接记录下来。最终出计费详单MOC时，将第一移动用户的CUG群码记录在MOC的CallerCUGInterlockCode字段、第二移动用户CUG群码记录在CalledCUGInterlockCode中；The originating MSC/VLR receives the routing information response, finds that the SRI-ACK contains the CUG group code and the CUG outgoing capability information, and records it directly. When MOC is finally issued, record the CUG group code of the first mobile user in the CallerCUGInterlockCode field of the MOC, and record the CUG group code of the second mobile user in CalledCUGInterlockCode;
发端MSC/VLR发现取回的是FTN号码，再次向HLR查询第三移动用户的信息，此时，将第二移动用户的CUG群码和CUG出群能力信息当作第一移动用户侧CUG信息发给HLR；The originating MSC/VLR finds that the retrieved FTN number is retrieved, and inquires the information of the third mobile user to the HLR again. At this time, the CUG group code and CUG group-out ability information of the second mobile user are regarded as the CUG information of the first mobile user side Send to HLR;
HLR查询第三移动用户的信息，根据第三移动用户的CUG群码进行CUG原则匹配，发现第二、三移动用户是同群用户，因此接受呼叫，查到第三移动用户的MSRN后就向发端MSC/VLR发送第二移动用户MSRN(移动台漫游号码)的同时，带上第二移动用户的CUG群码和CUG出群能力信息；HLR queries the information of the third mobile user, performs CUG principle matching according to the CUG group code of the third mobile user, finds that the second and third mobile users are users in the same group, therefore accepts the call, and sends the call after finding the MSRN of the third mobile user When the originating MSC/VLR sends the MSRN (mobile station roaming number) of the second mobile user, it also carries the CUG group code and CUG group-out ability information of the second mobile user;
发端MSC/VLR收到第二次路由信息响应，发现SRI-ACK中带有CUG群码和CUG出群能力信息，就直接记录下来。最终出计费详单CFW时，将第二移动用户的CUG群码记录在CFW的CallerCUGInterlockCode字段、第三移动用户的CUG群码记录在CalledCUGInterlockCode中；When the originating MSC/VLR receives the second routing information response, it finds that the SRI-ACK contains CUG group code and CUG outgoing group capability information, and records it directly.

计费中心在收到发端MSCA的MOC话单后，比较CallerCUGInterlockCode字段和CalledCUGInterlockCode字段的信息，一致(都为1)，则认为主、被叫用户为CUG同群用户，就给予主叫用户该群相应的资费优惠。相应的，计费中心在收到收端MSC B的MTC话单后，由于是智能网用户做被叫，被叫用户的资费已由SCP实时优惠，计费中心就不再处理(通过呼叫参考号关联删除)。另外，由于MSC主叫用户是被叫用户的触发局，有可能产生智能MTC话单，该话单计费中心也不作处理，此话单只作为跟SCP对帐的依据。After receiving the MOC bill of the originating MSCA, the billing center compares the information in the CallerCUGInterlockCode field and the CalledCUGInterlockCode field, and if they are consistent (both are 1), then the calling user and the called user are considered to be CUG users in the same group, and the calling user is given the group Corresponding tariff concessions. Correspondingly, after the billing center receives the MTC bill of the receiving end MSC B, because the intelligent network user is called, the tariff of the called user has been discounted by the SCP in real time, and the billing center will no longer process it (by calling the reference number association delete). In addition, since the MSC calling user is the triggering office of the called user, it is possible to generate an intelligent MTC bill, which will not be processed by the billing center, and this bill is only used as a basis for reconciliation with the SCP.
