该CSCF接收到上述第二指示消息后，根据接收到的用户标识信息，在归属用户服务器(HSS，Home Subscriber Server)中存储的用户的标识信息与用户签约的业务信息的对应关系中，查询与该用户的标识信息对应的该用户签约的业务信息，根据查询到的用户签约的业务信息，确定处理与查询到的业务信息对应的业务的设备，并将该用户的用户标识信息路由至确定的设备，以及通知确定的设备为该用户标识信息对应的用户提供对应的业务。After the CSCF receives the above-mentioned second indication message, according to the received user identification information, in the corresponding relationship between the user identification information stored in the Home Subscriber Server (HSS, Home Subscriber Server) and the service information signed by the user, query and According to the service information signed by the user corresponding to the user's identification information, according to the queried service information signed by the user, determine the equipment that processes the service corresponding to the queried service information, and route the user identification information of the user to the determined The device, and the device determined by the notification provides the corresponding service for the user corresponding to the user identification information.

在上述处理过程中，该用户的用户标识信息可以但不限于通过一个业务处理过程进行路由，例如，通过一个呼叫过程将用户的标识信息从第一通信网络路由至第二通信网络，此时，上述设备在为该用户提供对应的业务后，还需进一步将此业务处理过程路由至第一通信网络，具体为：该设备将此业务处理过程路由至CSCF，CSCF将此业务处理过程路由至上述MGCF，并向该MGCF发送用于指示MGCF将此业务处理过程路由至第一通信网络的第三指示消息，该MGCF根据接收到的第三指示消息，将此业务处理过程路由至第一通信网络中的SCP。In the above processing process, the user identification information of the user may be routed through a service processing process, for example, the user identification information is routed from the first communication network to the second communication network through a call process, at this time, After the above device provides the corresponding service for the user, it needs to further route the service processing process to the first communication network, specifically: the device routes the service processing process to the CSCF, and the CSCF routes the service processing process to the above-mentioned MGCF, and sending to the MGCF a third instruction message for instructing the MGCF to route the service processing procedure to the first communication network, and the MGCF routes the service processing procedure to the first communication network according to the received third instruction message SCP in.

其中，上述过程中的第一通信网络可以但不限于为CS域网络，第二通信网络可以但不限于为IMS网络。Wherein, the first communication network in the above process may be but not limited to a CS domain network, and the second communication network may be but not limited to an IMS network.

本发明实施例中的第一通信网络在判断出第一通信网络中用户已在第二通信网络中签约了业务时，指示第二通信网络根据该用户在第二通信网络中签约的业务信息，为该用户提供对应的业务，这就避免了CS域网络用户只能使用CS域网络为处于该网络内的用户提供的业务，实现了CS域网络用户能够使用IMS网络提供的业务。In the embodiment of the present invention, when the first communication network determines that the user in the first communication network has signed up for a service in the second communication network, it instructs the second communication network to, according to the service information signed by the user in the second communication network, Provide corresponding services for the user, which prevents the CS domain network users from only using the services provided by the CS domain network for users in the network, and enables the CS domain network users to use the services provided by the IMS network.

步骤49，MSC将此次呼叫路由至CS域网络和IMS网络之间的MGCF，即向MGCF发送IAM消息，IAM消息中的“被叫用户号码”参数为“toIMSBB”；Step 49, the MSC routes the call to the MGCF between the CS domain network and the IMS network, that is, sends an IAM message to the MGCF, and the "called user number" parameter in the IAM message is "toIMSBB";

步骤410，MGCF接收到MSC发送的IAM消息后，对消息中的“被叫用户号码”参数进行分析，根据“toIMS”确定此次呼叫的被叫用户为CS域网络用户并在IMS网络中签约了业务；Step 410: After receiving the IAM message sent by the MSC, the MGCF analyzes the "called user number" parameter in the message, and determines according to "toIMS" that the called user of this call is a CS domain network user and subscribed in the IMS network business;

步骤411，MGCF删除“toIMS”，得到用户B的真实号码BB；Step 411, MGCF deletes "toIMS", and obtains user B's real number BB;

步骤412，MGCF向IMS网络中的CSCF发送Invite消息，消息中携带有用户B的号码BB；Step 412, the MGCF sends an Invite message to the CSCF in the IMS network, and the message carries the number BB of user B;

步骤413，CSCF接收到Invite消息后，根据Invite消息中携带的用户B的号码BB，在HSS中存储的用户的号码信息与用户签约的业务信息的对应关系中，查询与用户B的号码信息对应的用户B签约的业务信息，确定用户B在IMS网络中签约的业务为业务2；Step 413, after CSCF receives the Invite message, according to the number BB of user B carried in the Invite message, in the corresponding relationship between the user's number information stored in the HSS and the service information signed by the user, query the correspondence between the number information of user B The service information signed by user B in the IMS network is determined as service 2;

步骤414，CSCF根据用户B的签约的业务信息，确定为用户B提供业务2的设备为设备2；Step 414, CSCF determines that the device providing service 2 for user B is device 2 according to the service information signed by user B;

步骤415，CSCF向设备2发送Invite消息，消息中携带用户B的号码BB；Step 415, CSCF sends an Invite message to device 2, and the message carries user B's number BB;

步骤416，设备2接收到Invite消息后，为用户B提供业务2。In step 416, device 2 provides service 2 for user B after receiving the Invite message.

在上述处理过程中，由于用户B为CS域网络用户，IMS网络在为用户B提供完业务2后，需要将呼叫路由至用户B所在的网络，即CS域网络，具体的方法流程如图5所示，其具体处理过程如下：In the above process, since user B is a CS domain network user, after the IMS network provides service 2 for user B, the call needs to be routed to the network where user B is located, that is, the CS domain network. The specific method flow is shown in Figure 5 As shown, the specific process is as follows:

步骤51，设备2在用户B的号码前插入前缀码“X”，并将“XBB”携带在Invite消息中的“被叫用户号码”参数中，用以指示CSCF将此次呼叫路由至CS网络；Step 51, device 2 inserts a prefix code "X" before user B's number, and carries "XBB" in the "called user number" parameter in the Invite message to instruct CSCF to route the call to the CS network ;

步骤52，设备2将此Invite消息发送给CSCF；Step 52, device 2 sends the Invite message to CSCF;

步骤53，CSCF接收到Invite消息后，根据“被叫用户号码”进行路由，即在电子编码服务器(ENUM，Electronic Numbering Server)中，查询“XBB”；Step 53, after the CSCF receives the Invite message, it performs routing according to the "called user number", that is, inquires "XBB" in the electronic numbering server (ENUM, Electronic Numbering Server);

步骤54，CSCF接收ENUM反馈的查询失败的结果信息；Step 54, CSCF receives the query failure result information fed back by ENUM;

步骤55，CSCF确定用户B为CS域网络用户，将呼叫路由至MGCF，即向MGCF发送上述Invite消息；Step 55, CSCF determines that user B is a CS domain network user, routes the call to MGCF, and sends the above-mentioned Invite message to MGCF;

步骤56，MGCF接收到Invite消息后，删除前缀码“X”，得到用户B的真实号码BB，并在IAM消息中增加“toCS”参数；Step 56: After receiving the Invite message, the MGCF deletes the prefix code "X", obtains the real number BB of user B, and adds the "toCS" parameter in the IAM message;

步骤57，MGCF将IAM消息发送给CS域网络的MSC；Step 57, the MGCF sends the IAM message to the MSC of the CS domain network;

步骤58，MSC根据IAM消息中的“toCS”参数，将呼叫路由至为用户B服务的SCP2，即向SCP2发送IDP消息，消息中携带有“toCS”参数；Step 58, MSC routes the call to SCP2 serving user B according to the "toCS" parameter in the IAM message, that is, sends an IDP message to SCP2, and the message carries the "toCS" parameter;

步骤59，SCP2根据IDP消息中携带的“toCS”参数，确定用户B在IMS网络中签约了业务，且已由IMS网络提供了对应的业务，因此将消息中的“toCS”参数删除；Step 59, SCP2 determines that user B has subscribed to a service in the IMS network according to the "toCS" parameter carried in the IDP message, and the corresponding service has been provided by the IMS network, so the "toCS" parameter in the message is deleted;

步骤510，SCP2向MSC发送Connect消息，消息中携带有用户A的号码AA和用户B的号码BB；Step 510, SCP2 sends a Connect message to the MSC, and the message carries the number AA of user A and the number BB of user B;

步骤511，MSC根据Connect消息，将此次呼叫路由至用户B。In step 511, the MSC routes the call to user B according to the Connect message.

上述处理过程中，设备2通过在被叫号码前插入特定的前缀码来使CSCF将呼叫路由至被叫用户所在的网络，此时CS域网络根据用户B的签约信息，确定用户B已在IMS网络中签约了业务，则根据图4所示的流程继续将此次呼叫路由至IMS网络，但是IMS网络已经为用户B提供了对应的业务，因此这就形成了业务的重复触发，本发明技术方案提出，MGCF在将呼叫路由至CS域网络的过程中，指示CS域网络不需要将呼叫重新路由至IMS网络，从而避免了重复触发业务的情况。During the above processing, device 2 inserts a specific prefix code before the called number to make the CSCF route the call to the network where the called user is located. At this time, the CS domain network determines that user B has registered in the IMS according to the subscription information of user B. If the service is signed in the network, the call will continue to be routed to the IMS network according to the flow shown in Figure 4, but the IMS network has provided the corresponding service for user B, so this has formed repeated triggering of the service, the technology of the present invention The solution proposes that, during the process of routing the call to the CS domain network, the MGCF instructs the CS domain network not to reroute the call to the IMS network, thereby avoiding repeated triggering of services.

其中，设备1和设备2可以为现有的应用服务器(AS，Application Server)，也可以为新增的只用来处理IMS网络为其他网络用户提供的业务的业务控制设备。Wherein, equipment 1 and equipment 2 can be existing application server (AS, Application Server), also can be newly-added service control equipment that is only used for processing the business that IMS network provides for other network users.

此外，本发明实施例中的前缀码不限于为上述“origtoIMS”、“toIMS”或“X”，在消息中增加的参数也不限于为“origto”或“toCS”。In addition, the prefix code in the embodiment of the present invention is not limited to the above "origtoIMS", "toIMS" or "X", and the parameters added in the message are not limited to "origto" or "toCS".

本发明实施例技术方案中，第一通信网络获取第一通信网络中用户的签约信息，在根据获取的签约信息，判断出该用户已在第二通信网络中签约了业务后，指示第二通信网络根据该用户在第二通信网络中签约的业务信息，为该用户提供对应的业务，这就避免了CS域网络用户只能使用CS域网络为处于该网络内的用户提供的业务，实现了CS域网络用户能够使用IMS网络提供的业务，例如CS域网络用户可以使用通过短号码互拨来实现通话等虚拟交换总机(Centrex，Centralized Exchange)业务，或CS域网络用户在拥有多个终端，并在呼叫过程中做主叫时对外显示统一的来电显示号码，在呼叫过程中做被叫时能够同时振铃或顺序振铃，由此可见，采用本发明实施例技术方案能够有效的提高两个相互独立的通信网络之间的业务融合性，使两个通信网络中的用户能够共享相同的业务所提供的便利。In the technical solution of the embodiment of the present invention, the first communication network obtains the subscription information of the user in the first communication network, and after judging that the user has signed a service in the second communication network according to the obtained subscription information, instructs the second communication network to The network provides corresponding services for the user according to the service information signed by the user in the second communication network, which prevents the CS domain network users from only using the services provided by the CS domain network for users in the network, and realizes CS domain network users can use the services provided by the IMS network. For example, CS domain network users can use virtual switchboard (Centrex, Centralized Exchange) services such as calls through short number mutual dialing, or CS domain network users have multiple terminals. And when the caller is called during the calling process, a unified caller ID number is displayed externally, and when the called party is called during the calling process, it can ring simultaneously or sequentially. It can be seen that the technical solution of the embodiment of the present invention can effectively improve the two The service convergence between mutually independent communication networks enables users in two communication networks to share the convenience provided by the same service.
