一种基于长期演进的语音呼叫业务处理方法、设备及系统A voice call service processing method, device and system based on long-term evolution

技术领域technical field

本发明涉及移动通信技术领域，尤其涉及一种VoLTE(Voice over Long Term Evolution，基于长期演进的语音呼叫)业务处理方法、设备及系统。The present invention relates to the technical field of mobile communication, in particular to a VoLTE (Voice over Long Term Evolution, voice call based on long-term evolution) service processing method, device and system.

背景技术Background technique

随着通信技术的发展，尤其是4G技术的进步，带动了高清语音通话、视频通话的蓬勃发展。其中，在LTE(Long Term Evolution，长期演进)时代，将以VoLTE作为语音技术的主要目标方案，以实现相应的高清语音通话、视频通话。With the development of communication technology, especially the advancement of 4G technology, it has driven the vigorous development of high-definition voice calls and video calls. Among them, in the era of LTE (Long Term Evolution, long-term evolution), VoLTE will be used as the main target solution of voice technology to realize corresponding high-definition voice calls and video calls.

具体地，目前，VoLTE技术仅能够在VoLTE终端上插卡使用，即在VoLTE终端上插入数据卡，如SIM(Subscriber Identity Module，客户识别模块)卡/USIM(Universal Subscriber Identity Module，全球用户识别模块)卡等，以通过数据卡实现与LTE核心网的通信链接，进而实现VoLTE音视频通话，从而导致存在所支持的终端类型及应用场景单一的缺陷，限制了VoLTE技术的拓展。Specifically, at present, VoLTE technology can only be used by inserting a card on a VoLTE terminal, that is, inserting a data card on a VoLTE terminal, such as a SIM (Subscriber Identity Module, customer identification module) card/USIM (Universal Subscriber Identity Module, global subscriber identity module ) card, etc., to realize the communication link with the LTE core network through the data card, and then realize the VoLTE audio and video call, which leads to the defects of single supported terminal types and application scenarios, which limits the expansion of VoLTE technology.

例如，对于平板电脑、笔记本电脑等无卡终端来说，虽然其目前可通过WiFi(Wireless-Fidelity，无线保真)等网络接入方式接入能够通过插卡方式(如插入相应的SIM卡/USIM卡等)接入相应LTE核心网的LTE接入网关，以实现无卡终端的即连即用，但是，由于其自身无法通过插卡方式实现相应的VoLTE音视频通话，因此，其若想实现相应的VoLTE音视频通话，则仅能通过实时多媒体通信技术向LTE接入网关发起相应呼叫请求的方式来实现。但是，由于现有的LTE接入网关无法识别无卡终端通过实时多媒体通信技术发送的呼叫请求、无法将其转换成LTE网络可以识别的呼叫建立信令并触发相应的呼叫建立流程，从而导致呼叫失败，即无法在无卡终端上实现相应的电信级 VoLTE通话。For example, for non-card terminals such as tablet computers and notebook computers, although they can be accessed through network access methods such as WiFi (Wireless-Fidelity, wireless fidelity) at present, they can be accessed by inserting a card (such as inserting a corresponding SIM card/ USIM card, etc.) is connected to the LTE access gateway of the corresponding LTE core network to realize instant connection and use of the terminal without a card. Realizing the corresponding VoLTE audio and video call can only be realized by initiating a corresponding call request to the LTE access gateway through the real-time multimedia communication technology. However, because the existing LTE access gateway cannot recognize the call request sent by the cardless terminal through real-time multimedia communication technology, and cannot convert it into call establishment signaling that the LTE network can recognize and trigger the corresponding call establishment process, resulting in call Failed, that is, the corresponding carrier-grade VoLTE call cannot be realized on the cardless terminal.

因此，亟需提供一种新的VoLTE业务处理方法，以解决现有技术中存在的无法在无卡终端上实现相应的电信级VoLTE通话、使得VoLTE技术所支持的终端类型及应用场景较为单一的问题。Therefore, there is an urgent need to provide a new VoLTE service processing method to solve the problems in the prior art that corresponding carrier-class VoLTE calls cannot be realized on cardless terminals, and the terminal types and application scenarios supported by VoLTE technology are relatively single. question.

In addition, it should be noted that each terminal connected to the LTE access gateway through the preset network access technology, including the POS phone, can be equivalent to the extended screen of the LTE access gateway. This is also not repeated.

步骤102：根据自身具备的与所述实时多媒体通信技术相对应的实时多媒体通信服务功能识别所述VoLTE呼叫请求，并将所述VoLTE呼叫请求转换为LTE核心网能够识别的呼叫建立信令。Step 102: Identify the VoLTE call request according to its own real-time multimedia communication service function corresponding to the real-time multimedia communication technology, and convert the VoLTE call request into call establishment signaling that can be recognized by the LTE core network.

也就是说，在本发明所述实施例中，可在现有LTE接入网关所具备的各功能的基础上，为其增设与相应的实时多媒体通信技术相对应的实时多媒体通信服务功能，以使其能够识别并转换终端通过实时多媒体通信技术发送的VoLTE呼叫请求。That is to say, in the embodiment of the present invention, on the basis of each function possessed by the existing LTE access gateway, a real-time multimedia communication service function corresponding to the corresponding real-time multimedia communication technology can be added for it, so as to It enables it to identify and convert the VoLTE call request sent by the terminal through real-time multimedia communication technology.

需要说明的是，本发明实施例中所述的增设有与相应的实时多媒体通信技术相对应的实时多媒体通信服务功能的LTE接入网关还可被称为VoLTE接入网关，本发明实施例对此不作赘述。It should be noted that the LTE access gateway described in the embodiment of the present invention with the added real-time multimedia communication service function corresponding to the corresponding real-time multimedia communication technology can also be called a VoLTE access gateway. This will not be repeated.

步骤103：将所述呼叫建立信令发送给所述LTE核心网，以触发VoLTE呼叫建立流程。Step 103: Send the call establishment signaling to the LTE core network to trigger a VoLTE call establishment process.

也就是说，在本发明实施例所述技术方案中，LTE接入网关能够识别所述终端通过实时多媒体通信技术发送的VoLTE呼叫请求，并且能将所述VoLTE呼叫请求转换为LTE核心网能够识别的呼叫建立信令并发送给所述LTE核心网，以触发VoLTE呼叫建立流程，从而实现了无需插卡即可在终端设备，如无卡终端设备上实现相应的电信级VoLTE通话的效果，克服了VoLTE技术所支持的终端类型及应用场景较为单一的缺陷，拓展了VoLTE技术的应用终端类型以及应用场景，提升了用户体验。That is to say, in the technical solution described in the embodiment of the present invention, the LTE access gateway can identify the VoLTE call request sent by the terminal through the real-time multimedia communication technology, and can convert the VoLTE call request into a VoLTE call request that can be identified by the LTE core network. The call establishment signaling is sent to the LTE core network to trigger the VoLTE call establishment process, thereby achieving the effect of corresponding carrier-grade VoLTE calls on terminal equipment without inserting a card, such as no-card terminal equipment, and overcoming It overcomes the shortcomings of relatively single terminal types and application scenarios supported by VoLTE technology, expands the application terminal types and application scenarios of VoLTE technology, and improves user experience.

进一步地，为了更清楚的说明本发明实施例所述技术方案，下面分别以无卡终端和有卡终端为例来简要说明本发明实施例所述的VoLTE业务处理过程。Further, in order to illustrate the technical solutions described in the embodiments of the present invention more clearly, the following uses a terminal without a card and a terminal with a card as examples to briefly describe the VoLTE service processing process described in the embodiments of the present invention.

具体地，现有技术中，对于无卡终端来说，由于无卡终端无数据卡(即SIM卡/USIM卡)，也就没有IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)，因此，若无卡终端希望进行VoLTE音视频通话，则会由于没有IMSI而无法实现LTE核心网的附着和注册，进而不能被LTE核心网识别，相应的就无法进行电信级VoLTE音视频通话。而在本发明实施例所述技术方案中，由于LTE接入网关具备与相应的实时多媒体通信技术相对应的实时多媒体通信服务功能，能够识别并转换终端通过实时多媒体通信技术发送的VoLTE呼叫请求，因而，无卡终端若希望进行VoLTE音视频通话，则可在通过WIFI等网络接入技术与LTE接入网关建立通信链接之后，通过实时多媒体通信技术，如Web RTC技术，向LTE接入网关发送相应的VoLTE呼叫请求，以由LTE接入网关根据自身具备的与所述实时多媒体通信技术相对应的实时多媒体通信服务功能识别所述VoLTE呼叫请求，并将所述VoLTE呼叫请求转换为LTE核心网能够识别的呼叫建立信令并发送给所述LTE核心网，以触发VoLTE呼叫建立流程，进而实现了无卡终端的电信级VoLTE通话，扩展了VoLTE技术的的应用终端类型以及应用场景，提升了用户体验。Specifically, in the prior art, for a cardless terminal, since the cardless terminal has no data card (ie SIM card/USIM card), there is no IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number), so , If the cardless terminal wants to make VoLTE audio and video calls, it will not be able to attach and register with the LTE core network because there is no IMSI, and thus cannot be recognized by the LTE core network, and correspondingly cannot make carrier-grade VoLTE audio and video calls. In the technical solution described in the embodiment of the present invention, since the LTE access gateway has a real-time multimedia communication service function corresponding to the corresponding real-time multimedia communication technology, it can identify and convert the VoLTE call request sent by the terminal through the real-time multimedia communication technology, Therefore, if a cardless terminal wants to make a VoLTE audio and video call, it can send a message to the LTE access gateway through a real-time multimedia communication technology, such as Web RTC technology, after establishing a communication link with the LTE access gateway through a network access technology such as WIFI. Corresponding VoLTE call request, to identify the VoLTE call request by the LTE access gateway according to its own real-time multimedia communication service function corresponding to the real-time multimedia communication technology, and convert the VoLTE call request to the LTE core network The call establishment signaling that can be identified is sent to the LTE core network to trigger the VoLTE call establishment process, thereby realizing carrier-grade VoLTE calls for cardless terminals, expanding the application terminal types and application scenarios of VoLTE technology, and improving the user experience.

对于有卡终端来说，在现有技术中，若其为VoLTE终端，则其可通过插入数据卡(如SIM卡/USIM卡等)的方式实现与LTE核心网的通信链接，进而实现VoLTE音视频通话，但是，存在所支持的终端类型及应用场景单一的缺陷，限制了VoLTE技术的拓展。而在本发明实施例所述技术方案中，无论该有卡终端是否为VoLTE终端都可以通过实时多媒体通信技术，如Web RTC技术，向LTE接入网关发送VoLTE呼叫请求，以由LTE接入网关根据自身具备的与所述实时多媒体通信技术相对应的实时多媒体通信服务功能识别该VoLTE呼叫请求，并将所述VoLTE呼叫请求转换为LTE核心网能够识别的呼叫建立信令并发送给所述LTE核心网，以触发VoLTE呼叫建立流程，进而实现终端的电信级VoLTE通话。也就是说，在本发明实施例所述技术方案中，对于有卡终端来说，除了可通过传统方式实现VoLTE音视频通话外，还可以通过实时多媒体通信技术向LTE接入网关发送VoLTE呼叫请求的方式，实现VoLTE音视频通话，从而极大地扩展了VoLTE技术的应用终端类型以及应用场景，提升了用户体验。For a terminal with a card, in the prior art, if it is a VoLTE terminal, it can realize a communication link with the LTE core network by inserting a data card (such as a SIM card/USIM card, etc.), thereby realizing VoLTE voice Video calls, however, have the disadvantage of single supported terminal types and application scenarios, which limits the expansion of VoLTE technology. In the technical solution described in the embodiment of the present invention, no matter whether the terminal with the card is a VoLTE terminal, it can send a VoLTE call request to the LTE access gateway through real-time multimedia communication technology, such as Web RTC technology, so that the LTE access gateway can Identify the VoLTE call request according to its own real-time multimedia communication service function corresponding to the real-time multimedia communication technology, and convert the VoLTE call request into a call establishment signaling that can be recognized by the LTE core network and send it to the LTE The core network can trigger the VoLTE call establishment process, and then realize the carrier-grade VoLTE call of the terminal. That is to say, in the technical solution described in the embodiment of the present invention, for a terminal with a card, in addition to realizing VoLTE audio and video calls in the traditional way, it can also send a VoLTE call request to the LTE access gateway through real-time multimedia communication technology In this way, VoLTE audio and video calls are realized, which greatly expands the application terminal types and application scenarios of VoLTE technology, and improves user experience.

进一步地，由于在VoLTE呼叫建立过程中或者VoLTE呼叫建立完成后的通话过程中，LTE接入网关需与LTE核心网以及终端等进行相应的信令交互，包括资源预留、媒体协商等；且，由于LTE核心网与LTE接入网关之间通常通过SIP协议进行信令交互，而LTE接入网关和终端之间可能是通过HTTP协议进行信令交互，因此，若在信令交互过程中，LTE接入网关直接将LTE核心网的信令转发给终端，则终端是无法识别的，因此，在本发明所述实施例中，LTE接入网关中可融合相应的协议转换逻辑功能，以对其两侧(即LTE核心网侧以及终端侧)的信令面协议、媒体面协议进行相应转换，以使得LTE接入网关向上能够识别和发送LTE核心网侧的信令和媒体指令，向下能够识别和发送终端侧的信令和媒体指令。Further, during the VoLTE call establishment process or the call process after the VoLTE call establishment is completed, the LTE access gateway needs to perform corresponding signaling interactions with the LTE core network and the terminal, including resource reservation, media negotiation, etc.; and , because the signaling interaction between the LTE core network and the LTE access gateway is usually through the SIP protocol, and the signaling interaction between the LTE access gateway and the terminal may be through the HTTP protocol, so if during the signaling interaction process, The LTE access gateway directly forwards the signaling of the LTE core network to the terminal, and the terminal cannot be identified. Therefore, in the embodiment of the present invention, the corresponding protocol conversion logic function can be integrated in the LTE access gateway to The signaling plane protocol and media plane protocol on both sides (ie, the LTE core network side and the terminal side) are converted accordingly, so that the LTE access gateway can identify and send the signaling and media instructions on the LTE core network side upwards, and downwards Capable of identifying and sending terminal-side signaling and media instructions.

也就是说，在本发明所述实施例中，所述方法还可包括：That is to say, in the embodiment of the present invention, the method may further include:

例如，在VoLTE呼叫建立过程中(如，LTE接入网关向LTE核心网发送呼叫建立信令以触发VoLTE呼叫建立流程，但尚未完成VoLTE呼叫建立前)，终端、LTE接入网关以及LTE核心网之间需进行信令交互，包括建立承载等，此时，由于LTE核心网与LTE接入网关之间通常通过SIP协议进行信令交互，而LTE接入网关和终端之间可能是通过HTTP协议进行信令交互，即，LTE接入网关两侧的信令协议不一致，导致无法成功建议承载，因此，在本发明所述实施例中，为了避免上述问题，所述LTE接入网关可通过其所具备的协议转换逻辑功能，对所述LTE接入网关的两侧的信令面协议进行转换，以将所述终端发送的信令转换成所述LTE核心网能够识别的信令，或者，将所述LTE核心网发送的信令转换成所述终端能够识别的信令，以实现VoLTE音视频的信令交互。For example, during the VoLTE call establishment process (for example, the LTE access gateway sends a call establishment signaling to the LTE core network to trigger the VoLTE call establishment process, but before the VoLTE call establishment is completed), the terminal, the LTE access gateway, and the LTE core network Signaling interaction is required between them, including bearer establishment, etc. At this time, because the signaling interaction between the LTE core network and the LTE access gateway is usually through the SIP protocol, and the LTE access gateway and the terminal may be through the HTTP protocol Signaling interaction, that is, the signaling protocols on both sides of the LTE access gateway are inconsistent, resulting in the failure to successfully propose a bearer. Therefore, in the embodiment of the present invention, in order to avoid the above problems, the LTE access gateway can use its The provided protocol conversion logic function converts the signaling plane protocols on both sides of the LTE access gateway, so as to convert the signaling sent by the terminal into signaling that can be recognized by the LTE core network, or, The signaling sent by the LTE core network is converted into signaling recognizable by the terminal, so as to realize signaling interaction of VoLTE audio and video.

同理，在通话过程中，终端、LTE接入网关以及LTE核心网之间进行信令、以及媒体信令的交互时，若LTE接入网关两侧的信令面协议及媒体面协议不一致，也会导致通话失败，因此，在本发明所述实施例中，为了避免上述问题，所述LTE接入网关可通过其所具备的协议转换逻辑功能，对所述LTE接入网关的两侧的信令面协议以及媒体面协议进行转换，以将所述终端发送的信令、媒体信令分别转换成所述LTE核心网可识别的信令及媒体信令并发送给所述LTE核心网，以及，将所述LTE核心网发送的信令、媒体信令分别转换成所述终端可识别的信令及媒体信令并发送给所述终端，进而实现正常的电信级VoLTE音视频通话。Similarly, during a call, when signaling and media signaling are interacted between the terminal, the LTE access gateway, and the LTE core network, if the signaling plane protocol and the media plane protocol on both sides of the LTE access gateway are inconsistent, It will also lead to call failure. Therefore, in the embodiment of the present invention, in order to avoid the above-mentioned problems, the LTE access gateway can use the protocol conversion logic function it possesses to control both sides of the LTE access gateway. converting the signaling plane protocol and the media plane protocol, so as to convert the signaling and media signaling sent by the terminal into signaling and media signaling recognizable by the LTE core network and send them to the LTE core network, And, the signaling and media signaling sent by the LTE core network are respectively converted into signaling and media signaling recognizable by the terminal and sent to the terminal, thereby realizing normal carrier-grade VoLTE audio and video calls.

另外，在VoLTE呼叫建立完成后的通话过程中，若确定所述LTE接入网关的上下行的音视频编解码方式不一致，则所述方法还可包括：In addition, during the call process after the VoLTE call is established, if it is determined that the uplink and downlink audio and video encoding and decoding methods of the LTE access gateway are inconsistent, the method may also include:

对所述LTE接入网关的两侧的音视频编解码方式进行转换，以将所述LTE接入网关与所述终端之间采用的音视频编解码方式转换成所述LTE接入网关与所述LTE核心网之间采用的音视频编解码方式，或者，将所述LTE接入网关与所述LTE核心网之间采用的音视频编解码方式转换成所述LTE接入网关与所述终端之间采用的音视频编解码方式。converting the audio and video codec modes on both sides of the LTE access gateway, so as to convert the audio and video codec mode adopted between the LTE access gateway and the terminal into the LTE access gateway and the The audio and video codec method used between the LTE core network, or convert the audio and video codec method used between the LTE access gateway and the LTE core network into the LTE access gateway and the terminal The audio and video codec methods used in between.

也就是说，在本发明所述实施例中，所述LTE接入网关还可具备相应的音视频编解码转换逻辑功能，以达到向上能够识别LTE核心网侧音视频编解码方式，向下能够识别终端侧音视频编解码方式，并在两侧音视频编解码不同时完成编解码方式的转换的效果。That is to say, in the embodiment of the present invention, the LTE access gateway can also have a corresponding audio and video codec conversion logic function, so as to achieve upward recognition of the LTE core network side audio and video codec mode, and downward ability to Identify the audio and video encoding and decoding methods on the terminal side, and complete the conversion of the encoding and decoding methods when the audio and video encoding and decoding methods on both sides are different.

进一步地，所述方法还可包括：Further, the method may also include:

也就是说，本发明所述实施例除了可实现VoLTE呼叫建立之外，还可实现VoLTE切换、VoLTE挂断等基于VoLTE的一系列会话请求操作，本发明对此不作限定。另外需要说明的是，本发明实施例中所述的VoLTE呼叫建立不仅局限于一路音视频会话的建立，还包括多方音视频会话的建立，本发明实施例对此不作赘述。That is to say, in addition to implementing VoLTE call establishment, the embodiments of the present invention can also implement a series of VoLTE-based session request operations such as VoLTE switching and VoLTE hanging up, which are not limited in the present invention. In addition, it should be noted that the establishment of a VoLTE call in the embodiment of the present invention is not limited to the establishment of one audio and video session, but also includes the establishment of a multi-party audio and video session, which will not be described in this embodiment of the present invention.

下面，将以一具体实例为例对本申请实施例一中所述的VoLTE业务处理方法进行详细说明。In the following, a specific example will be taken as an example to describe the VoLTE service processing method described in Embodiment 1 of the present application in detail.

假设，所述终端为无卡终端，如个人电脑，所述终端接入LTE接入网关的方式为WIFI接入方式，所述终端所采用的实时多媒体通信技术为Web RTC技术，则所述VoLTE业务处理方法可包括以下步骤：Assuming that the terminal is a non-card terminal, such as a personal computer, the way the terminal accesses the LTE access gateway is WIFI access, and the real-time multimedia communication technology adopted by the terminal is Web RTC technology, then the VoLTE The business processing method may include the following steps:

步骤S1：个人电脑通过WIFI接入LTE接入网关。Step S1: The personal computer accesses the LTE access gateway through WIFI.

具体地，与现有技术类似，本发明实施例中所述的LTE接入网关可通过插入USIM卡等，上行通过LTE无线接入LTE核心网，下行利用WIFI信号等接入用户侧终端设备，如平板电脑、智能终端、个人电脑等，实现无卡多媒体终端的即连即用，以为终端提供数据、互联网等融合业务，并且，其还具有网点离散、安全性高、开通便利等特点。Specifically, similar to the prior art, the LTE access gateway described in the embodiments of the present invention can access the LTE core network through LTE wireless uplink by inserting a USIM card, etc., and access the user-side terminal equipment through WIFI signals in the downlink, Such as tablet PCs, smart terminals, personal computers, etc., realize the instant connection and use of cardless multimedia terminals, and provide data, Internet and other integrated services for the terminals. Moreover, it also has the characteristics of discrete outlets, high security, and convenient activation.

步骤S2：个人电脑打开支持多媒体实时通信能力的浏览器，并在该浏览器的地址栏中输入LTE接入网关推送的拨号页面地址以打开相应的拨号页面，以及，在该拨号页面内打开LTE接入网关推送的拨号界面。Step S2: the personal computer opens a browser supporting multimedia real-time communication capability, and enters the dial-up page address pushed by the LTE access gateway in the address bar of the browser to open the corresponding dial-up page, and opens the LTE in the dial-up page Access the dial interface pushed by the gateway.

步骤S3：个人电脑基于该拨号页面向LTE接入网关发起基于Web RTC的VoLTE呼叫请求，即，在拨号界面内进行拨号操作，比如拨打10086。Step S3: The personal computer initiates a Web RTC-based VoLTE call request to the LTE access gateway based on the dialing page, that is, performs a dialing operation in the dialing interface, such as dialing 10086.

也就是说，当个人电脑等无卡终端希望进行VoLTE音视频通话时，因终端内无SIM卡，无法实现运营商核心网的附着和注册，因此不被运营商核心网识别，无法进行电信级的VoLTE音视频通话，因此，需通过相应的Web RTC等多媒体实时通信技术向LTE接入网关发起相应的VoLTE呼叫请求。That is to say, when a terminal without a card such as a personal computer wants to make a VoLTE audio and video call, because there is no SIM card in the terminal, the attachment and registration of the operator's core network cannot be achieved, so it is not recognized by the operator's core network and cannot be used for carrier-grade communication. Therefore, it is necessary to initiate a corresponding VoLTE call request to the LTE access gateway through the corresponding multimedia real-time communication technology such as Web RTC.

具体地，此时，用户通过个人电脑发起的拨号等操作指令可被LTE接入网关识别，等同于在LTE接入网关上直接进行拨号，即，此时，LTE接入网关相对于LTE核心网来说相当于一个普通的VoLTE终端，而通过WIFI等接入技术接入LTE接入网关的终端设备，如个人电脑等，其功能可仅相当于VoLTE接入网关的一个拨号屏幕，本发明实施例对此不作赘述。Specifically, at this time, the operation commands such as dialing initiated by the user through the personal computer can be recognized by the LTE access gateway, which is equivalent to directly dialing on the LTE access gateway. It is equivalent to an ordinary VoLTE terminal, and the terminal equipment that accesses the LTE access gateway through access technologies such as WIFI, such as a personal computer, etc., its function can only be equivalent to a dial screen of the VoLTE access gateway. Examples will not be described here.

步骤S4：LTE接入网关根据自身具备的与所述Web RTC相对应的实时多媒体通信服务功能，即Web RTC Server功能，识别所述VoLTE呼叫请求，并将所述VoLTE呼叫请求转换为LTE核心网能够识别的呼叫建立信令发送给LTE核心网，以触发VoLTE呼叫建立流程。Step S4: The LTE access gateway identifies the VoLTE call request according to its own real-time multimedia communication service function corresponding to the Web RTC, that is, the Web RTC Server function, and converts the VoLTE call request into an LTE core network The identifiable call setup signaling is sent to the LTE core network to trigger the VoLTE call setup process.

也就是说，由于LTE接入网关具备Web RTC Server功能，能够识别终端发起的基于Web RTC的VoLTE呼叫请求，即拨号请求，因此，可完成相应的拨号，并向核心网发送呼叫建立信令，如INVITE信令，以请求建立通话。That is to say, since the LTE access gateway has the function of Web RTC Server, it can identify the VoLTE call request based on Web RTC initiated by the terminal, that is, the dial request, so it can complete the corresponding dial and send the call establishment signaling to the core network. Such as INVITE signaling to request to establish a call.

具体地，在建立通话时，即在VoLTE呼叫建立过程中，LTE核心网和LTE接入网关等需先进行信令交互，包括资源预留、媒体协商等，此时存在一个问题：即LTE核心网与LTE接入网关之间通常通过SIP协议进行信令交互，而LTE接入网关和终端之间可能是通过HTTP协议进行信令交互，因此，若在信令交互过程中，LTE接入网关直接将LTE核心网的信令转发给终端，则终端是无法识别的，因此，在本发明所述实施例中，LTE接入网关中可融合相应的协议转换逻辑功能，以对其两侧的信令面协议、媒体面协议进行相应转换，以使得LTE接入网关向上能够识别和发送LTE核心网侧的信令和媒体指令，向下能够识别和发送终端侧的信令和媒体指令，本发明实施例对此不作赘述。Specifically, when establishing a call, that is, during the establishment of a VoLTE call, the LTE core network and the LTE access gateway need to perform signaling interaction first, including resource reservation, media negotiation, etc. At this time, there is a problem: the LTE core The SIP protocol is usually used for signaling interaction between the network and the LTE access gateway, and the HTTP protocol may be used for signaling interaction between the LTE access gateway and the terminal. Therefore, if the signaling interaction process is performed, the LTE access gateway If the signaling of the LTE core network is directly forwarded to the terminal, the terminal cannot be identified. Therefore, in the embodiment of the present invention, the corresponding protocol conversion logic function can be integrated in the LTE access gateway to control the The signaling plane protocol and the media plane protocol are converted accordingly, so that the LTE access gateway can identify and send the signaling and media instructions on the LTE core network side upwards, and can identify and send the signaling and media instructions on the terminal side downwards. The embodiment of the invention does not repeat this.

步骤S5：呼叫建立后，被叫终端开始振铃，当被叫接通电话时，双方可开始进行VoLTE音视频通话。Step S5: After the call is established, the called terminal starts ringing, and when the called terminal connects to the phone, both parties can start a VoLTE audio and video call.
