技术领域Technical field

本发明涉及通信领域，特别是涉及一种IMS终端自组网的方法及装置。The present invention relates to the field of communications, and in particular, to a method and apparatus for an IMS terminal ad hoc network.

背景技术Background technique

IP多媒体子***(IP Multimedia Subsystem，IMS)是一种全新的多媒体业务形式，它能够满足现在的终端客户更新颖、更多样化的多媒体业务的需求，已经被公认为3G后通信网络的核心关键技术，是实现固网、移动网和互联网融合的必选的网络架构，是目前网络技术研究的前沿和热点技术。IP Multimedia Subsystem (IMS) is a new form of multimedia service that meets the needs of today's end-users for newer and more diverse multimedia services. It has been recognized as the core of 3G post-communication networks. The key technology is the mandatory network architecture for the convergence of fixed network, mobile network and Internet. It is the forefront and hotspot technology of network technology research.

IMS终端在注册时需要设定代理会话控制功能(Proxy-Call Session Control Funtion，P-CSCF)发现点，并经过会话初始协议(Session Initiation Protocol，SIP)消息向IMS网络设备注册。The IMS terminal needs to set a Proxy-Call Session Control Fun (P-CSCF) discovery point when registering, and register with the IMS network device through a Session Initiation Protocol (SIP) message.

具体的，参阅图1所示，以IMS终端A的注册流程为例进行说明，IMS终端A在开机后，通过SIP信令向IMS网络发起注册流程，并经过IMS网络内部P-CSCF网元、查询会话控制功能(Interrogating-Call Session Control Funtion，I-CSCF)网元、服务会话控制功能(Serving-Call Session Control Funtion，S-CSCF)网元、归属用户服务器(Home Subscriber Server，HSS)、应用服务器(Application Server，AS)记录IMS终端A的信息，并为后续呼叫等业务做准备。此外，IMS终端B也需执行上述流程实现在IMS网络中的注册。Specifically, as shown in FIG. 1 , the registration process of the IMS terminal A is taken as an example. After the IMS terminal A is powered on, the registration process is initiated to the IMS network through the SIP signaling, and the internal P-CSCF network element of the IMS network is used. Interrogating-Call Session Control Funnel (I-CSCF) network element, Serving-Call Session Control Funtion (S-CSCF) network element, Home Subscriber Server (HSS), application The Application Server (AS) records the information of the IMS terminal A and prepares for services such as subsequent calls. In addition, the IMS terminal B also needs to perform the above process to implement registration in the IMS network.

在呼叫流程中，当IMS终端A需要向IMS终端B发起呼叫时，主叫IMS终端A需要发起SIP呼叫(INVITE)信令，也由IMS网络中的各个网元进行路由转发，此外，IMS终端之间传输的媒体包也需要由IMS网络设备中的各个网元进行转发。因此，IMS终端必须接入到IMS网络的环境中才能进行呼叫等业务，如果IMS终端接入到IMS网络失败，则此时IMS终端无法正常工作，在一定程度上限制了IMS终端的应用场景。In the call flow, when the IMS terminal A needs to initiate a call to the IMS terminal B, the calling IMS terminal A needs to initiate SIP call (INVITE) signaling, and is also routed and forwarded by each network element in the IMS network. In addition, the IMS terminal The media packets transmitted between them also need to be forwarded by each network element in the IMS network device. Therefore, the IMS terminal must be connected to the IMS network environment to perform services such as calling. If the IMS terminal fails to access the IMS network, the IMS terminal cannot work normally, which limits the application scenario of the IMS terminal to a certain extent.

现有技术下，IMS终端之间在进行视频、音频、短信等基础业务时，还会经常出现IMS网络内部网元丢包等情况，导致业务进程异常。In the prior art, when the basic services such as video, audio, and short message are performed between the IMS terminals, the internal network element of the IMS network is often lost, which causes the service process to be abnormal.

具体的，可能有以下至少两种情况导致丢包现象：Specifically, there may be at least two cases that result in packet loss:

其一，为了保证数据包传输实时性，IMS媒体数据包的发送通常采用用户数据报协议(User Datagram Protocol，UDP)传输IMS网络中的数据包，而UDP传输是不可靠的传输，丢包是数据包传输过程中的正常现象。因此，在数据包的传输过程中，每增加一个中间节点，丢包的可能性都会增加。而针对IMS终端之间的呼叫过程，需要IMS网络中的多个设备进行转发，因此可能导致较高的丢包率。First, in order to ensure the real-time transmission of data packets, the IMS media data packet is usually sent using the User Datagram Protocol (User). Datagram Protocol (UDP) transmits data packets in an IMS network, while UDP transmission is an unreliable transmission. Packet loss is a normal phenomenon during data packet transmission. Therefore, in the process of data packet transmission, the probability of packet loss increases every time an intermediate node is added. For the call process between IMS terminals, multiple devices in the IMS network need to be forwarded, which may result in a high packet loss rate.

其二，由于所有IMS终端发起业务时都需要使用一整套IMS网络设备，而当IMS设备需要对大量数据包进行处理时，由于IMS网络设备的处理能力有限，因此也会造成一定的丢包现象。例如，大量音视频数据包的解码和编码过程需要占用IMS设备的大量资源，对IMS设备的负荷构成极大的挑战，因此也可能出现丢包现象。Second, since all IMS terminals need to use a complete set of IMS network devices when initiating services, when the IMS devices need to process a large number of data packets, due to the limited processing capability of the IMS network devices, a certain packet loss phenomenon may also occur. . For example, the decoding and encoding process of a large number of audio and video data packets requires a large amount of resources of the IMS device, which poses a great challenge to the load of the IMS device, and thus packet loss may occur.

由上可知，IMS终端在注册和发起业务的过程中，均需要部署一整套IMS网络设备提供为其提供服务，极大地限制了IMS终端的应用场景，且业务进程中较高的丢包率可能导致业务进程出现异常。It can be seen that the IMS terminal needs to deploy a complete set of IMS network devices to provide services for the IMS terminal in the process of registering and initiating services, which greatly limits the application scenarios of the IMS terminal, and the high packet loss rate in the service process may be Causes an abnormality in the business process.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

为了解决现有技术中IMS终端应用场景受限以及网络丢包率较高的问题，本发明提出了一种IMS终端自组网的方法及装置，该方法为：第一IMS终端经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端，注册广播消息携带第一IMS终端的标识和地址；第一IMS终端接收所在互通集群网络中至少一个IMS终端回复的注册广播确认消息，并记录接收到的每一条注册广播确认消息中携带的相应的IMS终端的标识与地址；第一IMS终端确定第一IMS终端与接收到的每一条注册广播确认消息对应的IMS终端共同构成IMS自适应网络。In order to solve the problem that the IMS terminal application scenario is limited and the network packet loss rate is high in the prior art, the present invention provides a method and device for an IMS terminal ad hoc network, where the first IMS terminal is sent by the switching device. Registered widely Broadcasting the message to the other IMS terminal in the interworking cluster network, the registration broadcast message carries the identifier and address of the first IMS terminal; the first IMS terminal receives the registration broadcast acknowledgement message replied by at least one IMS terminal in the interworking cluster network, and records The identifier and address of the corresponding IMS terminal carried in each of the received registration broadcast acknowledgement messages; the first IMS terminal determines that the first IMS terminal and the received IMS terminal corresponding to each registered broadcast acknowledgement message together constitute an IMS adaptive network .

下面结合附图对本发明优选的实施方式进行详细说明。Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

参阅图2所示，本发明实施例中IMS终端自组网的具体流程如下：Referring to FIG. 2, the specific process of the IMS terminal ad hoc network in the embodiment of the present invention is as follows:

首先，在第一IMS终端的注册过程中，在以下至少两种情况下，触发第一IMS终端经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端：First, in the registration process of the first IMS terminal, in at least two cases, the first IMS terminal is triggered to send the registration broadcast message to other IMS terminals in the interworking cluster network via the switching device:

其一，第一IMS终端每次确定自身开机时，经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端。First, each time the first IMS terminal determines that it is powered on, the switching device sends a registration broadcast message to other IMS terminals in the interworking cluster network.

其二，第一IMS终端每次确定到达预设的重注册周期时，经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端。Second, each time the first IMS terminal determines to reach the preset re-registration period, the switching device sends a registration broadcast message to other IMS terminals in the interworking cluster network.

具体的，可以设置重注册周期为5秒。设置重注册周期，可以保证IMS终端在某次注册流程未完成时，在下次继续执行注册流程，并可以及时发现更多的其他IMS终端。Specifically, the re-registration period can be set to 5 seconds. By setting the re-registration period, the IMS terminal can continue to perform the registration process next time when a registration process is not completed, and can discover more other IMS terminals in time.

步骤200：第一IMS终端经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端，注册广播消息携带第一IMS终端的标识和地址。Step 200: The first IMS terminal sends the registration broadcast message to other IMS terminals in the interworking cluster network by the switching device, and the registration broadcast message carries the identifier and address of the first IMS terminal.

具体的，第一IMS终端将注册广播消息发送至交换设备，例如，交换机等，再由交换设备转发至互通集群网络中的各个其他IMS终端，这里的互通集群网络可以是指第一IMS终端所在的局域网，也可以是与第一IMS终端所在局域网能够实现互通、支持路由转发的几个网络。Specifically, the first IMS terminal sends the registration broadcast message to the switching device, for example, the switch, and the like, and then the switching device forwards to each other IMS terminal in the interworking cluster network, where the interworking cluster network may refer to the first IMS terminal. The local area network may also be a network that can communicate with the local area network where the first IMS terminal is located and supports routing and forwarding.

其中，第一IMS网络发送的注册广播消中息携带第一IMS终端的标识和地址，这里的地址可以为IP地址。The registered broadcast mediation sent by the first IMS network carries the identifier and address of the first IMS terminal, where the address may be an IP address.

例如，以图3为例，IMS终端X经交换设备发送注册广播消息至自身所在局域网中的IMS终端A至IMS终端E。For example, taking FIG. 3 as an example, the IMS terminal X sends a registration broadcast message to the IMS terminal A to the IMS terminal E in the local area network through the switching device.

此外，在第一IMS终端经交换设备发送注册广播消息至自身所在互通集群网络中的其他IMS终端时，进一步包括：In addition, when the first IMS terminal sends the registration broadcast message to the other IMS terminal in the interworking cluster network by the switching device, the method further includes:

第一IMS终端经交换设备发送注册消息至IMS网络中的代理会话控制功能网元P-CSCF，在IMS网络中进行注册。The first IMS terminal sends a registration message to the proxy session control function network element P-CSCF in the IMS network via the switching device, and registers in the IMS network.

须知第一IMS终端同时将注册消息和注册广播消息发送至交换设备，并由交换设备将注册消息转发至P-CSCF，进行标准的IMS网络注册流程，而将注册广播消息转发至第一IMS终端所在互通集群网络中的其他IMS终端。It should be noted that the first IMS terminal simultaneously sends the registration message and the registration broadcast message to the switching device, and the switching device forwards the registration message to the P-CSCF, performs a standard IMS network registration procedure, and forwards the registration broadcast message to the first IMS terminal. Other IMS terminals in the interworking cluster network.

步骤210：第一IMS终端接收所在互通集群网络中至少一个IMS终端回复的注册广播确认消息，并记录接收到的每一条注册广播确认消息中携带的相应的IMS终端的标识与地址。Step 210: The first IMS terminal receives a registration broadcast replied by at least one IMS terminal in the interworking cluster network. The acknowledgement message is recorded, and the identifier and address of the corresponding IMS terminal carried in each of the received registration broadcast acknowledgement messages are recorded.

例如，这里的注册广播确认消息可以为SIP 200 OK，并在该注册广播确认消息中携带发送该注册广播确认消息的IMS终端的标识和地址。以图3为例，IMS终端B回复SIP 200 OK至IMS终端X，该SIP 200 OK消息中携带IMS终端B的标识和IP地址。For example, the registration broadcast acknowledgement message here may be a SIP 200 OK, and the identifier and address of the IMS terminal that sends the registration broadcast acknowledgement message are carried in the registration broadcast acknowledgement message. Taking FIG. 3 as an example, the IMS terminal B replies to the SIP 200 OK to the IMS terminal X, and the SIP 200 OK message carries the identifier and IP address of the IMS terminal B.

第一IMS终端根据接收到的每一条注册广播确认消息，记录对应每一条注册广播确认消息的IMS终端的标识与地址，建立IMS终端与其对应地址的关系表。The first IMS terminal records the identifier and address of the IMS terminal corresponding to each registered broadcast acknowledgement message according to each received registration broadcast acknowledgement message, and establishes a relationship table between the IMS terminal and its corresponding address.

又例如，仍以图3为例，IMS终端A至IMS终端E分别回复SIP 200 OK至IMS终端X。IMS根据接收到的每一条注册广播确认消息，记录对应每一条注册广播确认消息的IMS终端的标识与地址，如下表1所示。For another example, still taking FIG. 3 as an example, the IMS terminal A to the IMS terminal E respectively reply to the SIP 200 OK to the IMS terminal X. The IMS records the identifier and address of the IMS terminal corresponding to each registered broadcast acknowledgement message according to each received broadcast acknowledgement message, as shown in Table 1 below.

表1Table 1

IMS终端标识IMS terminal identification	IMS终端地址IMS terminal address
AA	192.168.1.2192.168.1.2
BB	192.168.1.9192.168.1.9
CC	192.168.1.70192.168.1.70
DD	192.168.1.24192.168.1.24
EE	192.168.1.18192.168.1.18

进一步地，在第一IMS终端发起呼叫业务时，当第一IMS终端需要与任一IMS终端建立呼叫关系时，以IMS终端A为例，第一IMS终端首先根据接收到的每一条注册广播确认消息中携带的相应的IMS终端的标识与地址，查询IMS终端A的标识与地址的对应关系。Further, when the first IMS terminal initiates a call service, when the first IMS terminal needs to establish a call relationship with any IMS terminal, taking the IMS terminal A as an example, the first IMS terminal first confirms according to each received registration broadcast. The identifier and address of the corresponding IMS terminal carried in the message are used to query the correspondence between the identifier and the address of the IMS terminal A.

当第一IMS终端确定记录有IMS终端A的标识与地址时，第一IMS终端直接向IMS终端A对应的地址发送呼叫消息。When the first IMS terminal determines that the identifier and address of the IMS terminal A are recorded, the first IMS terminal directly sends a call message to the address corresponding to the IMS terminal A.

这里的呼叫消息为INVITE消息，第一IMS终端确定记录IMS有终端A的标识与地址，表明第一IMS终端与IMS终端A同在一个互通集群网络中，在双方的注册过程中，彼此记录有对方的标识和地址，因此，此时无需再经过IMS网络中的各个网元进行转发，直接进行旁路处理，即可完成两个IMS终端之间的呼叫流程，摆脱了对IMS网络的依赖，实现了IMS终端点对点的通信。The call message here is an INVITE message, and the first IMS terminal determines that the record IMS has the identifier and address of the terminal A, indicating that the first IMS terminal and the IMS terminal A are in the same inter-cluster network, and during the registration process of the two parties, The identity and address of the other party. Therefore, at this time, it is no longer necessary to go through the forwarding of each network element in the IMS network, and the bypass processing can be directly performed to complete the call flow between the two IMS terminals, and get rid of the dependence on the IMS network. The point-to-point communication of the IMS terminal is realized.

此外，当第一IMS终端确定没有记录IMS终端A的标识与地址时，第一IMS终端进一步判断自身是否在IMS网络注册成功。In addition, when the first IMS terminal determines that the identity and address of the IMS terminal A are not recorded, the first IMS terminal further determines whether it is successfully registered in the IMS network.

其中，第一IMS终端确定没有记录IMS终端A的标识与地址，表明第一IMS终端与IMS终端A不在同在一个互通集群网络中，在双方的注册过程中，没有互相通信。由于在第一IMS终端的注册过程中，第一IMS终端同时向IMS网络进行注册，该IMS网络注册过程为现有的标准流程，因此，若第一IMS终端确定自身在IMS网络注册成功，则经交换设备将呼叫消息发送至P-CSCF，并通过IMS网络中的各个网元转发至IMS终端A，此处执行的是现有的流程。The first IMS terminal determines that the identifier and address of the IMS terminal A are not recorded, indicating that the first IMS terminal and the IMS terminal A are not in the same inter-cluster network, and do not communicate with each other during the registration process of the two parties. Due to During the registration process of the first IMS terminal, the first IMS terminal simultaneously registers with the IMS network, and the IMS network registration process is an existing standard process. Therefore, if the first IMS terminal determines that it is successfully registered in the IMS network, it is exchanged. The device sends a call message to the P-CSCF and forwards it to the IMS terminal A through each network element in the IMS network, where the existing process is performed.

因此，当第一IMS终端在IMS网络注册成功时，由于第一IMS终端同时发送了注册广播消息，所以当其在呼叫同一互通集群网络中的其他终端时，进行旁路处理，直接向对方地址发送INVITE消息，减轻了IMS网络的负担，扩展了IMS终端的应用场景，而当第一IMS终端呼叫其他外网的IMS终端时，通过IMS网络中各个网元转发INVITE消息至对应的IMS终端。Therefore, when the first IMS terminal successfully registers in the IMS network, since the first IMS terminal simultaneously sends the registration broadcast message, when it calls other terminals in the same interworking cluster network, the bypass processing is performed, and the address is directly addressed to the other party. The INVITE message is sent to reduce the burden on the IMS network, and the application scenario of the IMS terminal is extended. When the first IMS terminal calls the IMS terminal of the other external network, the INVITE message is forwarded to the corresponding IMS terminal by each network element in the IMS network.

若第一IMS终端确定自身在IMS网络注册失败，且呼叫的IMS终端A为外网的IMS终端时，将会导致呼叫失败，第一IMS终端终止与IMS终端A建立呼叫关系。If the first IMS terminal determines that the registration of the IMS network fails, and the IMS terminal A of the call is the IMS terminal of the external network, the call will fail, and the first IMS terminal terminates the establishment of the call relationship with the IMS terminal A.

步骤220：第一IMS终端确定第一IMS终端与接收到的每一条注册广播确认消息对应的IMS终端共同构成IMS自适应网络。Step 220: The first IMS terminal determines that the first IMS terminal and the received IMS terminal corresponding to each registration broadcast acknowledgement message jointly form an IMS adaptive network.

参阅图4所示，本发明实施例中IMS终端自组网的具体流程如下：Referring to FIG. 4, the specific process of the IMS terminal ad hoc network in the embodiment of the present invention is as follows:

步骤400：第二IMS终端接收自身所在互通集群网络中第一IMS终端经交换设备转发的注册广播消息，并记录注册广播消息中携带的第一IMS终端的标识与地址。Step 400: The second IMS terminal receives the registration broadcast message forwarded by the first IMS terminal in the interworking cluster network by the switching device, and records the identifier and address of the first IMS terminal carried in the registration broadcast message.

具体的，以图3中的IMS终端B为例，此时，IMS终端B接收到自身所在互通集群网络中IMS终端X发送的注册广播消息，该注册广播消息携带IMS终端X的标识和地址，记录IMS终端X的标识和地址。Specifically, the IMS terminal B in FIG. 3 is taken as an example. At this time, the IMS terminal B receives the registration broadcast message sent by the IMS terminal X in the interworking cluster network, and the registration broadcast message carries the identifier and address of the IMS terminal X. Record the identity and address of the IMS terminal X.

步骤410：第二IMS终端向第一IMS终端回复注册广播确认消息，其中，注册广播确认消息携带第二IMS终端的标识和地址。Step 410: The second IMS terminal replies to the first IMS terminal with a registration broadcast acknowledgement message, where the registration broadcast acknowledgement message carries the identifier and address of the second IMS terminal.

具体的，以图3中的IMS终端B为例，IMS终端B回复SIP 200 OK至IMS终端X，并在该SIP 200 OK消息中携带IMS终端B的标识和IP地址。Specifically, taking the IMS terminal B in FIG. 3 as an example, the IMS terminal B replies to the SIP 200 OK to the IMS terminal X, and carries the identifier and IP address of the IMS terminal B in the SIP 200 OK message.

步骤420：第二IMS终端确定第二IMS终端与第一IMS终端共同构成IMS自适应网络。Step 420: The second IMS terminal determines that the second IMS terminal and the first IMS terminal jointly form an IMS adaptive network.

因此，对于一个IMS终端而言，当其在注册流程中，IMS终端发送注册广播消息至所在互通集群网络中的其他IMS终端，并根据接收到的注册广播确认消息，记录每一条注册广播确认消息对应的IMS终端的标识和地址，与此同时，该IMS终端也接收同在一个互通集群网络中其他终端发送的注册广播消息，并回复注册广播确认消息至对应的终端，以及记录接收到的注册广播消息对应的IMS终端的标识和地址。因此，同在一个互通集群网络中的IMS终端构成IMS自适应网络。Therefore, for an IMS terminal, when it is in the registration process, the IMS terminal sends a registration broadcast message to other IMS terminals in the inter-cluster network, and records each registration broadcast acknowledgement message according to the received registration broadcast acknowledgement message. The identifier and address of the corresponding IMS terminal, meanwhile, the IMS terminal also receives the registration broadcast message sent by other terminals in an interworking cluster network, and replies to the registration broadcast confirmation message to the corresponding terminal, and records the received registration. The identifier and address of the IMS terminal corresponding to the broadcast message. Therefore, the IMS terminal in the same interworking cluster network constitutes an IMS adaptive network.

实施例1：Example 1:

图5所示，为IMS终端A在开机时的注册流程： Figure 5 shows the registration process of IMS terminal A at boot time:

其中，交换设备以交换机为例，图5中的IMS网络中网元除P-CSCF外，均省略未画出。The switching device takes a switch as an example. The network elements in the IMS network in FIG. 5 are omitted except for the P-CSCF.

步骤501：IMS终端A向交换机同时发送注册消息和注册广播消息。Step 501: The IMS terminal A simultaneously sends a registration message and a registration broadcast message to the switch.

步骤502：交换机将注册广播消息发送至与IMS终端A同在一个局域网的IMS终端B和IMS终端C。Step 502: The switch sends the registration broadcast message to the IMS terminal B and the IMS terminal C in the same local area network as the IMS terminal A.

步骤503：交换机将注册消息发送至P-CSCF，发起IMS终端A在IMS网络的注册流程。Step 503: The switch sends a registration message to the P-CSCF, and initiates a registration process of the IMS terminal A in the IMS network.

步骤504：IMS终端B根据IMS终端A发送的注册广播消息，记录IMS终端A的标识和地址，并发送注册广播确认消息200 OK至IMS终端A，该注册广播确认消息中携带IMS终端B的标识和地址。Step 504: The IMS terminal B records the identifier and address of the IMS terminal A according to the registration broadcast message sent by the IMS terminal A, and sends a registration broadcast acknowledge message 200 OK to the IMS terminal A, where the registration broadcast acknowledge message carries the identifier of the IMS terminal B. And address.

步骤505：IMS终端A根据IMS终端B回复的注册广播确认消息，记录IMS终端B的标识和地址。Step 505: The IMS terminal A records the identity and address of the IMS terminal B according to the registration broadcast acknowledgement message replied by the IMS terminal B.

步骤506：IMS终端C记录根据IMS终端A发送的注册广播消息，记录IMS终端A的标识和地址，并发送注册广播确认消息200 OK至IMS终端A，该注册广播确认消息中携带IMS终端C的标识和地址。Step 506: The IMS terminal C records the registration broadcast message sent by the IMS terminal A, records the identifier and address of the IMS terminal A, and sends a registration broadcast acknowledge message 200 OK to the IMS terminal A, where the registration broadcast acknowledge message carries the IMS terminal C. Identification and address.

步骤507：IMS终端A根据IMS终端C回复的注册广播确认消息，记录IMS终端C的标识和地址。Step 507: The IMS terminal A records the identifier and address of the IMS terminal C according to the registration broadcast acknowledgement message replied by the IMS terminal C.

因此，IMS终端A、IMS终端B、IMS终端C共同构成IMS自适应网络。Therefore, the IMS terminal A, the IMS terminal B, and the IMS terminal C together constitute an IMS adaptive network.

图6所示，为IMS终端A与IMS终端B的呼叫关系建立流程：FIG. 6 shows a call relationship establishment process between the IMS terminal A and the IMS terminal B:

这里假设IMS终端A和IMS终端B为同在一个局域网中的两个IMS终端，且在两个IMS终端的注册过程中，各自分别保存了对方的标识和地址。It is assumed here that the IMS terminal A and the IMS terminal B are two IMS terminals in the same local area network, and in the registration process of the two IMS terminals, the identity and address of the other party are respectively saved.

同在一个IMS自适应网络的IMS终端A和IMS终端B，当IMS终端A与IMS终端B建立呼叫关系时，包括：When the IMS terminal A and the IMS terminal B establish a call relationship with the IMS terminal A and the IMS terminal B, the IMS terminal A and the IMS terminal B include:

步骤601：IMS终端A查询有IMS终端B的标识和地址，确定记录有IMS终端B的标识和地址，直接发送INVITE消息至IMS终端B。Step 601: The IMS terminal A queries the identifier and address of the IMS terminal B, determines the identity and address of the IMS terminal B, and directly sends the INVITE message to the IMS terminal B.

步骤602：IMS终端B回复确认消息200 OK至IMS终端A。Step 602: The IMS terminal B replies with an acknowledgment message 200 OK to the IMS terminal A.

步骤603：IMS终端A回复确认消息ACK至IMS终端B，IMS终端A与IMS终端B的呼叫关系建立成功。Step 603: The IMS terminal A replies with an acknowledgment message ACK to the IMS terminal B, and the call relationship between the IMS terminal A and the IMS terminal B is successfully established.

上述过程中，IMS终端A和IMS终端B可直接进行点对点的通信，无需IMS网络转发，此外，在IMS终端A与IMS终端B的呼叫关系建立成功后，两者可以直接互传音视频媒体数据包，也无需再通过IMS网络进行转发。减轻了IMS网络数据包转发压力，降低丢包概率。In the above process, the IMS terminal A and the IMS terminal B can directly perform point-to-point communication without the IMS network forwarding. In addition, after the call relationship between the IMS terminal A and the IMS terminal B is successfully established, the two can directly transmit audio and video media data. Packets do not need to be forwarded through the IMS network. It reduces the packet forwarding pressure of the IMS network and reduces the probability of packet loss.
