Perform multimedia data transmission.

图2为本发明实施例提供的一种多媒体数据传输的方法的通信示意图。本发明实施例中涉及第一终端和第二终端，且可以在第一终端和第二终端上安装客户识别模块(Subscriber Identification Module，SIM)、全球用户识别卡(Universal Subscriber Identity Module，USIM)、通用集成电路卡(Universal Integrated Circuit Card，UICC)、嵌入式SIM(eSIM)卡或嵌入式UICC(eUICC)卡等。插卡后的第一终端和第二终端可以支持第二代手机通信技术(2-Generation wireless telephone technology，2G)、第三代移动通信技术(3rd-Generation mobile communication technology，3G)或***移动通信技术(4rd-Generation mobile communication technology，4G)，但无法获取与终端绑定的号码。例如，第一终端和第二终端中安装有支持2G或3G的SIM卡。因运营商并未在SIM卡中写入该SIM卡的号码，即移动台国际用户地址号码(Mobile Station International Subscriber Directory Number，MSISDN)，所以装入该SIM卡的终端，无法读取SIM卡的号码。需要说明的是，对于第一终端或第二终端，已经获取与终端绑定的号码的情况，也可以采用本实施例提供的多媒体数据传输的方法。如图2所示，该实施例可以包括：FIG. 2 is a schematic diagram of communication of a method for transmitting multimedia data according to an embodiment of the present invention. In the embodiment of the present invention, the first terminal and the second terminal are involved, and a Subscriber Identification Module (SIM), a Universal Subscriber Identity Module (USIM), and a Universal Subscriber Identity Module (USIM) may be installed on the first terminal and the second terminal. Universal Integrated Circuit Card (UICC), embedded SIM (eSIM) card or embedded UICC (eUICC) card. The first terminal and the second terminal after the card can support the second generation mobile telephone communication technology (2G), the third generation mobile communication technology (3G) or the fourth generation 4rd-Generation mobile communication technology (4G), but the number bound to the terminal cannot be obtained. For example, a SIM card supporting 2G or 3G is installed in the first terminal and the second terminal. Since the operator does not write the SIM card number in the SIM card, that is, the Mobile Station International Subscriber Directory Number (MSISDN), the terminal loaded in the SIM card cannot read the SIM card. number. It should be noted that, for the case that the first terminal or the second terminal has obtained the number bound to the terminal, the method for transmitting multimedia data provided by this embodiment may also be used. As shown in FIG. 2, this embodiment may include:

步骤201，第一终端向第二终端发送推送请求消息，该消息用于请求服务器生成令牌并建立令牌与第一终端的对应关系。Step 201: The first terminal sends a push request message to the second terminal, where the message is used to request the server to generate a token. And establishing a correspondence between the token and the first terminal.

需要说明的是，令牌可以用于唯一标识本次第一终端和第二终端之间的多媒体会话。例如，第一终端与服务器之间，以及第二终端与服务器之间的通信交互都需要携带该令牌，当本次呼叫业务结束后，令牌失效。结束本次呼叫后，第一终端向第二终端再次发起呼叫时，需要向服务器发送推送请求消息，用于请求服务器生成令牌，以唯一标识再次发起的呼叫业务。通过生成令牌唯一标识每次呼叫业务，可以限制第一终端和第二终端只能在当前的通话过程中进行做媒体数据传输业务，以提高终端之间多媒体通信的安全性。同时，因服务器在第一终端和第二终端首次建立呼叫业务的过程中，已经记录第一终端和第二终端的多媒体能力，所以，第一终端和第二终端在后续建立呼叫业务的过程中，可以不再向服务器发送各自的多媒体能力信息。示例性的，当第一终端向第二终端发起呼叫时，第一终端与服务器建立第一连接(例如，HTTP连接)，并通过第一连接向第二终端发送推送请求消息。It should be noted that the token may be used to uniquely identify the multimedia session between the first terminal and the second terminal. For example, the communication between the first terminal and the server, and the communication between the second terminal and the server need to carry the token. When the call service ends, the token is invalid. After the call is terminated, the first terminal sends a push request message to the server to request the server to generate a token to uniquely identify the re-initiated call service. By generating a token to uniquely identify each call service, the first terminal and the second terminal can be restricted to perform media data transmission services only during the current call process, so as to improve the security of multimedia communication between the terminals. At the same time, the first terminal and the second terminal have recorded the multimedia capability of the first terminal and the second terminal in the process of the first terminal and the second terminal establishing the call service for the first time. You can no longer send their own multimedia capability information to the server. Exemplarily, when the first terminal initiates a call to the second terminal, the first terminal establishes a first connection (eg, an HTTP connection) with the server, and sends a push request message to the second terminal through the first connection.

示例性的，推送请求消息包括第一终端的识别码。其中，第一终端的识别码用于标识第一连接，以防止持有第一终端的用户存在一个号码同时在多个终端使用的情况。例如，某用户持有安装有SIM卡A的终端A、安装有SIM卡B的终端B和安装有SIM卡C的终端C，且SIM卡A、SIM卡B和SIM卡C共享一个号码。当用户使用终端A(第一终端)向第二终端发起呼叫业务时，终端A与服务器建立第一连接，当服务器从第二终端接收终端A的号码，并根据终端A的号码向终端A发送信息，但因终端B和终端C的号码与终端A相同，将无法确定应该向哪一个终端发送。又例如，某用户的平板电脑和车载电话，通过网络服务与该用户的手机共享一个手机号，即该平板电脑和车载电话均通过网络服务绑定该用户的手机号，当该用户的手机向第二终端发起呼叫业务时，该用户的手机与服务器建立第一连接，并通过第一连接向服务器发送手机的识别码，当服务器从第二终端接收手机的号码，并根据该手机的号码向手机发送信息时，虽然平板电脑和车载装置也共享该手机号，但服务器可以根据已接收的识别码确定向手机发送信息。Exemplarily, the push request message includes an identification code of the first terminal. The identifier of the first terminal is used to identify the first connection, so as to prevent the user holding the first terminal from having one number at the same time and using it in multiple terminals. For example, a user holds a terminal A on which a SIM card A is installed, a terminal B on which a SIM card B is installed, and a terminal C on which a SIM card C is installed, and the SIM card A, the SIM card B, and the SIM card C share a single number. When the user initiates a call service to the second terminal by using the terminal A (the first terminal), the terminal A establishes a first connection with the server, and when the server receives the number of the terminal A from the second terminal, and sends the terminal A to the terminal A according to the number of the terminal A. Information, but since the numbers of Terminal B and Terminal C are the same as those of Terminal A, it will not be possible to determine which terminal should be sent. For another example, a user's tablet computer and a car phone share a mobile phone number with the user's mobile phone through a network service, that is, the tablet computer and the car phone phone both bind the user's mobile phone number through a network service, when the user's mobile phone is directed to When the second terminal initiates the call service, the mobile phone of the user establishes a first connection with the server, and sends the identification code of the mobile phone to the server through the first connection, when the server receives the number of the mobile phone from the second terminal, and according to the number of the mobile phone When the mobile phone sends the information, although the tablet computer and the in-vehicle device share the mobile phone number, the server can determine to send the information to the mobile phone according to the received identification code.

示例性的，第一终端为移动电话，在一种可能的实施方式中，识别码为国际移动设备识别码(International Mobile station Equipment Identity，IMEI)。IMEI由15位数字组成，存储在移动电话的电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，EEPROM)中，每台移动电话在组装完成后都将被赋予全球唯一的IMEI，且该IMEI从移动电话生产到交付使用都将被制造生产的厂商所记录。在另一种可能的实施方式中，识别码为国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)。IMSI存储在SIM卡或USIM卡中，每一张SIM卡或USIM卡都具有唯一的IMSI，IMSI是区别移动用户的有效标志。在又一种可能的实施方式中，识别码为公民网络电子身份标识(Electronic Identity，eID)，eID存储在嵌入式UICC卡中，用于唯一标识每一张UICC卡。示例性的，推送请求消息包括第二终端的号码。需要说明的是，在后续步骤中，第二终端可以从服务器接收第二终端的号码。第二终端在获取与第二终端绑定的号码之后，可以采用本发明实施例中如图5-7和图9中任一附图示出的方法与第一终端或第三终端传输多媒体数据。Exemplarily, the first terminal is a mobile phone. In a possible implementation manner, the identifier is an International Mobile Station Equipment Identity (IMEI). The IMEI consists of 15 digits and is stored in the Electrically Erasable Programmable Read-Only Memory (EEPROM). Each mobile phone will be given the world's only IMEI after assembly. And the IMEI will be recorded by the manufacturer of the manufacturing from the production of the mobile phone to the delivery. In another possible implementation manner, the identifier is an International Mobile Subscriber Identification Number (IMSI). The IMSI is stored in a SIM card or a USIM card. Each SIM card or USIM card has a unique IMSI, which is a valid identifier for distinguishing mobile users. In another possible implementation manner, the identifier is a citizen network electronic identity (eID), and the eID is stored in the embedded UICC card for uniquely identifying each UICC card. Illustratively, the push request message includes the number of the second terminal. It should be noted that, in a subsequent step, the second terminal may receive the number of the second terminal from the server. After acquiring the number bound to the second terminal, the second terminal may transmit the multimedia data to the first terminal or the third terminal by using the method shown in any of FIG. 5-7 and FIG. 9 in the embodiment of the present invention. .

示例性的，推送请求消息包括第一终端的能力集。需要说明的是，在后续步骤中，服务器可以向第二终端发送第一终端的能力集，以使第二终端可以根据第一终端的能力集或第二终端的能力集与第一终端的能力集的交集向第一终端发送多媒体数据。其中，能力集是终端支持的多媒体能力的集合。例如，第一终端支持的多媒体能力的数据结构为：Exemplarily, the push request message includes a capability set of the first terminal. It should be noted that, in a subsequent step, the server may send the capability set of the first terminal to the second terminal, so that the second terminal may be based on the capability set of the first terminal or The intersection of the capability set of the second terminal and the capability set of the first terminal sends multimedia data to the first terminal. Among them, the capability set is a collection of multimedia capabilities supported by the terminal. For example, the data structure of the multimedia capability supported by the first terminal is:

MultiMediaCapability::＝MultiMediaCapability::=

{{

VideoConferenceSupported,VideoConferenceSupported,

LocationShareSupported,LocationShareSupported,

PictureSendSupportedPictureSendSupported

}}

其中，MultiMediaCapability表示多媒体能力；VideoConferenceSupported表示视频通话能力，如果其值为0则表示支持视频通话，如果其值为1则表示不支持视频通话；LocationShareSupported表示位置共享能力，如果其值为0则表示支持位置共享，如果其值为1则表示不支持位置共享；PictureSendSupported表示图片发送能力，如果其值为0则表示支持位置共享发送图片，如果其值为1则表示不支持发送图片。Among them, MultiMediaCapability represents multimedia capability; VideoConferenceSupported represents video call capability, if its value is 0, it means support for video call, if its value is 1, it means that video call is not supported; LocationShareSupported means location sharing capability, if its value is 0, it means support Location sharing. If the value is 1, it means that location sharing is not supported. PictureSendSupported indicates the image sending capability. If the value is 0, it means that the location sharing sending picture is supported. If the value is 1, it means that the picture is not supported.

步骤202，服务器生成令牌，并建立令牌与第一终端的对应关系，以及向第一终端发送该令牌。Step 202: The server generates a token, establishes a correspondence between the token and the first terminal, and sends the token to the first terminal.

示例性的，服务器根据第二终端的号码生成令牌，并建立令牌与第一连接的对应关系，以及向第一终端发送推送响应消息，该消息中携带该令牌。Exemplarily, the server generates a token according to the number of the second terminal, and establishes a correspondence between the token and the first connection, and sends a push response message to the first terminal, where the message carries the token.

示例性的，推送响应消息中还携带首次推送(Beckon)标识。该标识用于指示第一终端在向第二终端发送的呼叫信令中携带令牌。Exemplarily, the push response message also carries a first push (Beckon) logo. The identifier is used to indicate that the first terminal carries the token in the call signaling sent to the second terminal.

步骤203，第一终端向第二终端发送呼叫信令，呼叫信令包括该令牌。Step 203: The first terminal sends call signaling to the second terminal, where the call signaling includes the token.

示例性的，在步骤203之前，还可以包括：第一终端从服务器接收首次推送(Beckon)标识。该标识用于指示第一终端在向第二终端发送的呼叫信令中携带令牌。Exemplarily, before step 203, the method may further include: receiving, by the first terminal, a first push (Beckon) identifier from the server. The identifier is used to indicate that the first terminal carries the token in the call signaling sent to the second terminal.

示例性的，第一终端向第二终端发送呼叫信令，根据首次推送标识，在呼叫信令中携带用户到用户(User to User Signaling，UUS)信元，并通过UUS信元传送令牌。例如，第一终端向第二终端发送呼叫建立消息(SETUP)，呼叫建立消息中携带UUS信元，UUS信元承载有令牌。Exemplarily, the first terminal sends the call signaling to the second terminal, and carries the User to User Signaling (UUS) cell in the call signaling according to the first push identifier, and transmits the token through the UUS cell. For example, the first terminal sends a call setup message (SETUP) to the second terminal, where the call setup message carries the UUS cell, and the UUS cell carries the token.

可选的，步骤204，第一终端从第二终端接收呼叫建立响应消息(SETUP_ACK)，该消息用于告知第一终端：第二终端已收到呼叫建立消息。需要说明的是，可以在执行下述步骤(步骤205-步骤214)中的任一步骤的同时，之前，或者之后执行步骤204，本发明实施例对此不作限定。Optionally, in step 204, the first terminal receives a call setup response message (SETUP_ACK) from the second terminal, where the message is used to notify the first terminal that the second terminal has received the call setup message. It should be noted that the step 204 is performed before, before, or after any of the following steps (step 205-step 214), which is not limited by the embodiment of the present invention.

示例性的，呼叫信令中可以包括第一终端的号码。例如，第二终端已开通了来电显示业务或加装了来电显示器，当第二终端接收第一终端发送的呼叫信令后，第二终端可以显示第一终端的号码。Exemplarily, the number of the first terminal may be included in the call signaling. For example, the second terminal has opened the caller ID service or installed the caller ID display. After the second terminal receives the call signaling sent by the first terminal, the second terminal can display the number of the first terminal.

步骤205，服务器从第二终端接收第二终端的能力集和令牌，并建立令牌与第二终端的对应关系。Step 205: The server receives the capability set and the token of the second terminal from the second terminal, and establishes a correspondence between the token and the second terminal.

示例性的，第二终端与服务器建立第二连接(例如，HTTP连接)，并通过第二连接向服务器发送令牌和第二终端的能力集。示例性的，第二终端向服务器发送匹配业务请求消息(MatchReq)，匹配业务请求消息包括令牌和第二终端的能力集。匹配业务请求消息用于请求与第一终端进行多媒体能力信息匹配。其中，多媒体能力信息匹配包括：获取第一终端的能力集与第二终端的能力集的交集，或获取第一终端支持的会话描述协议(Session Description Protocol，SDP)的参数等。Exemplarily, the second terminal establishes a second connection (eg, an HTTP connection) with the server, and sends the token and the capability set of the second terminal to the server through the second connection. Exemplarily, the second terminal sends a matching service request message (MatchReq) to the server, where the matching service request message includes the token and the capability set of the second terminal. The matching service request message is used to request matching of the multimedia capability information with the first terminal. The multimedia capability information matching includes: acquiring the first The intersection of the capability set of the terminal and the capability set of the second terminal, or the parameters of the Session Description Protocol (SDP) supported by the first terminal.

SDP用于两个会话实体之间的媒体协商，并两个会话实体之间的SDP的参数达成一致。协商的SDP的参数包括IP地址、端口，媒体编码格式和媒体类型(如音频、视频)等。The SDP is used for media negotiation between two session entities, and the parameters of the SDP between the two session entities are agreed.

示例性的，服务器建立令牌、第二终端的识别码与第二终端的对应关系。其中，第二终端的识别码用于标识第二连接，以防止持有第二终端的用户存在一个号码同时在多个终端使用的情况。Exemplarily, the server establishes a token, a correspondence between the identifier of the second terminal, and the second terminal. The identification code of the second terminal is used to identify the second connection, so as to prevent the user holding the second terminal from having one number at the same time and using it in multiple terminals.

示例性的，在步骤205中还可以包括步骤2051：服务器建立第一终端的识别码与第一终端的号码的对应关系，以及第二终端的识别码与第二终端的号码的对应关系。当第一终端的用户通过服务器根据第二终端的号码发送多媒体数据时，服务器可以根据第二终端的号码向第二终端发送多媒体数据。Exemplarily, in step 205, the method may further include a step 2051: the server establishes a correspondence between the identifier of the first terminal and the number of the first terminal, and a correspondence between the identifier of the second terminal and the number of the second terminal. When the user of the first terminal sends the multimedia data according to the number of the second terminal by the server, the server may send the multimedia data to the second terminal according to the number of the second terminal.

步骤206，服务器向第一终端发送第二终端的能力集。Step 206: The server sends the capability set of the second terminal to the first terminal.

示例性的，服务器向第一终端发送创建指令消息(Create Command)，该消息包括令牌和第二终端的能力集，该消息用于指示第一终端可以创建多媒体业务。其中，创建多媒体业务包括：向第二终端发送第一终端支持的SDP的参数和多媒体数据，以及从第二终端接收多媒体数据等。Exemplarily, the server sends a Create Command message to the first terminal, where the message includes a token and a capability set of the second terminal, the message is used to indicate that the first terminal can create a multimedia service.

步骤208，第一终端向服务器发送第一转发请求消息，该消息携带第一终端的能力集与第二终端的能力集的交集以及第一终端的SDP文本信息(SDPa)。其中，SDPa包括第一终端可以使用的多个IP地址和多个端口信息，以及媒体编码格式和媒体类型等。服务器确定与SDPa相应的SDP文本信息(SDPy)。其中，SDP文本信息包括会话名称和意图、会话持续时间、构成会话的媒体和有关接收媒体的信息(如，地址)等。Step 208: The first terminal sends a first forwarding request message to the server, where the message carries the intersection of the capability set of the first terminal and the capability set of the second terminal, and the SDP text information (SDPa) of the first terminal. The SDPa includes a plurality of IP addresses and a plurality of port information that the first terminal can use, a media encoding format, a media type, and the like. The server determines the SDP text information (SDPy) corresponding to the SDPa. The SDP text information includes a session name and an intent, a session duration, a media constituting the session, and information (eg, an address) related to the received media.

需要说明的是，SDP是一种会话描述格式，它不属于传输协议，且它只能使用适当的不同的传输协议。所述传输协议包括会话通知协议(Session Announcement Protocol，SAP)、会话初始协议(Session Initiation Protocol，SIP)、实时流协议(Real Time Streaming Protocol，RTSP)、多用途互联网邮件扩展((Multipurpose Internet Mail Extensions，MIME)协议的电子邮件以及超文本传输协议(HyperText Transfer Protocol，HTTP)。例如，在因特网的组播骨干网(multicast backbone，Mbone)中，会话目录工具被用于通告多媒体会议，并为参与者传送会议地址和参与者所需的会议特定工具信息，这由SDP完成。SDP连接好会话后，传送足够的信息给会话参与者。SDP信息的发送利用了SAP，SAP周期性地组播通知数据包到已知组播地址和端口处。其中的数据包是用户数据报协议(User Datagram Protocol，UDP)数据包，数据包中包含SAP协议头和文本有效载荷(text payload)，此处的文本有效载荷即为SDP文本信息。It should be noted that SDP is a session description format, which is not a transport protocol, and it can only use a different and different transport protocol. The transmission protocol includes a Session Announcement Protocol (SAP), a Session Initiation Protocol (SIP), a Real Time Streaming Protocol (RTSP), and a Multipurpose Internet Mail Extensions. , MIME) protocol email and HyperText Transfer Protocol (HTTP). For example, in the Internet's multicast backbone (Mbone), the session directory tool is used to advertise multimedia conferences and participate The conference address and the conference-specific tool information required by the participant are transmitted, which is completed by the SDP. After the SDP connects the session, sufficient information is transmitted to the session participants. The SDP information is transmitted using SAP, and the SAP periodically multicasts the notification. The data packet is sent to a known multicast address and port. The data packet is a User Datagram Protocol (UDP) data packet, and the data packet includes an SAP protocol header and a text payload. The text payload is the SDP text message.

示例性的，在步骤208之前，还可以包括：第一终端确定第一终端的能力集与第二终端的能力集的交集。此时，第一终端的可以根据该交集改变第一终端的多媒体通信标识的状态。例如，如图3(a)和(b)所示，当第一终端未确定交集时，“视频通话”按钮、“语音通话”按钮、“图片发送”按钮、“视频发送”按钮，“文件发送”按钮，“位置共享”按钮均显示为灰色，即禁止状态，此时点击按钮无效。当第一终端接收第二终端的能力集后，因确定的交集指示只支持语音通话、图片发送、位置共享业务，且不支持其他业务，第一终端显示屏上与所支持业务相对应的“语音通话”按钮、“图片发送”按钮和“位置共享”按钮显示为可点击状态，即可以通过点击按钮进行相应业务。Exemplarily, before step 208, the method may further include: determining, by the first terminal, a capability set and a second terminal of the first terminal The intersection of the set of capabilities of the end. At this time, the state of the multimedia communication identifier of the first terminal may be changed according to the intersection of the first terminal. For example, as shown in FIGS. 3(a) and (b), when the first terminal does not determine the intersection, the "video call" button, the "voice call" button, the "picture send" button, the "video send" button, "file" The Send button and the Location Sharing button are all displayed in gray, that is, the disabled state, and the click button is invalid. After the first terminal receives the capability set of the second terminal, the determined intersection indication only supports the voice call, the picture sending, the location sharing service, and does not support other services, and the first terminal display screen corresponds to the supported service. The Voice Call button, the Picture Send button, and the Location Sharing button are displayed in a clickable state, that is, the corresponding service can be performed by clicking a button.

步骤209，服务器向第二终端发送匹配业务响应消息(MatchAck)，该消息中携带第一终端的能力集与第二终端的能力集的交集以及SDPy。Step 209: The server sends a matching service response message (MatchAck) to the second terminal, where the message carries the intersection of the capability set of the first terminal and the capability set of the second terminal, and SDPy.

示例性的，匹配业务相应消息中携带第二终端的号码。Exemplarily, the corresponding message of the matching service carries the number of the second terminal.

示例性的，在步骤209之后，还可以包括步骤2091：第二终端记录第二终端的号码。第二终端在获取与第二终端绑定的号码之后，可以采用本发明实施例中的如图4-图9中任一附图其他示出的方法与第一终端或第三终端传输多媒体数据。Exemplarily, after step 209, step 2091 may be further included: the second terminal records the number of the second terminal.

示例性的，在步骤211之前，还可以包括：服务器确定SDPx。Exemplarily, before step 211, the method may further include: determining, by the server, SDPx.

需要说明的是，1)在第一终端与服务器，以及第二终端与服务器之间交互的信息中，可以均携带有令牌，用于服务器根据令牌对第一终端和第二终端之间的信息进行中转。It should be noted that: 1) the information exchanged between the first terminal and the server, and the second terminal and the server may carry a token for the server to use between the first terminal and the second terminal according to the token. The information is relayed.

2)当本实施例中的服务器仅作为交换第一终端和第二终端的多媒体能力的服务器时，上述服务器的SDP文本信息需要通过其他服务器(即用于交换第一终端和第二终端的多媒体数据的服务器)进行分配。而当本实施例中的服务器同时作为第一终端和第二终端之间交换多媒体能力和多媒体数据的服务器时，服务器的SDP文本信息可以由该服务器自己进行分配。2) When the server in this embodiment is only used as a server for exchanging multimedia capabilities of the first terminal and the second terminal, the SDP text information of the server needs to pass through other servers (ie, multimedia for exchanging the first terminal and the second terminal) The server of the data is allocated. When the server in this embodiment simultaneously serves as a server for exchanging multimedia capabilities and multimedia data between the first terminal and the second terminal, the SDP text information of the server can be allocated by the server itself.

3)SDP文本信息由许多文本行组成，文本行的格式为<类型>＝<值>，<类型>是一个字母，<值>是结构化的文本串，其格式依<类型>而定。SDP文本信息中包括会话信息和媒体信息。其中，会话信息包括会话名和目的，以及会话活动时间。由于参与会话的资源是受限制的，因此包括会话使用的带宽信息和会话负责人的联系信息等附加信息是非常有用的。而媒体信息包括媒体类型，例如视频和音频；传输协议，例如UDP/IP和H.320；媒体格式，例如H.261视频和MPEG视频；多播地址和媒体传输端口(IP多播会话)；用于联系地址的媒体和传输端口的远端地址(IP单播会话)。因SDP文本信息中可以包括对应终端的IP地址信息。第二终端在获取第一终端的能力集和第二终端的能力集的交集，以及通过SDPy获取第一终端的IP地址后，可以直接根据该交集和第一终端的IP地址与第一终端进行通信，包括发送和接收多媒体数据。同样的，第一终端在确定第一终端的能力集和第二终端的能力集的交集，以及通过SDPx获取第二终端的IP地址后，可以直接根据第二终端的IP地址与第二终端进行通信，包括发送和接收多媒体数据。例如，第一终端和第二终端之间是公网，第一终端可以根据第二终端的IP地址直接向第二终端发送图片或语音消息。又例如，第一终端和第二终端上网使用的接入点均为电信网络的***互联网(China Mobile Network，CMNET)接入点。第一终端根据第二终端的IP地址向第二终端发送能力集、第一终端的IP地址以及第一终端的端口号。3) SDP text information consists of many lines of text. The format of the text line is <type>=<value>, <type> is a letter, and <value> is a structured text string whose format depends on <type>. The SDP text information includes session information and media information. The session information includes the session name and purpose, and the session activity time. Since the resources participating in the session are restricted, additional information such as the bandwidth information used by the session and the contact information of the session leader is very useful. Media information includes media types such as video and audio; transport protocols such as UDP/IP and H.320; media formats such as H.261 video and MPEG video; multicast address and media transport port (IP multicast session); The remote address (IP unicast session) of the media and transport port used to contact the address. The IP address information of the corresponding terminal may be included in the SDP text information. After acquiring the intersection of the capability set of the first terminal and the capability set of the second terminal, and acquiring the IP address of the first terminal by using the SDPy, the second terminal may directly perform the first terminal according to the intersection and the IP address of the first terminal. Communication, including sending and receiving multimedia data.

Communication, including sending and receiving multimedia data. For example, a public network is between the first terminal and the second terminal, and the first terminal may directly send a picture or a picture to the second terminal according to the IP address of the second terminal. Voice messages. For another example, the access points used by the first terminal and the second terminal to access the Internet are all China Mobile Network (CMNET) access points of the telecommunication network. The first terminal sends the capability set, the IP address of the first terminal, and the port number of the first terminal to the second terminal according to the IP address of the second terminal.

步骤213，第一终端向服务器发送多媒体数据。Step 213: The first terminal sends multimedia data to the server.

示例性的，在执行步骤213的同时，或之前，或之后，还可以包括：第二终端向服务器发送多媒体数据，第一终端从服务器接收多媒体数据。例如，第二终端根据从服务器接收的第一终端的能力集与第二终端的能力集的交集以及SDPb，向服务器发送多媒体数据，第一终端从服务器接收多媒体数据。Exemplarily, at the same time as, before, or after the step 213, the second terminal may further include: the second terminal sends the multimedia data to the server, and the first terminal receives the multimedia data from the server. For example, the second terminal transmits multimedia data to the server according to the intersection of the capability set of the first terminal received from the server and the capability set of the second terminal and the SDPb, and the first terminal receives the multimedia data from the server.

步骤214，第二终端从服务器接收多媒体数据。Step 214: The second terminal receives multimedia data from the server.

After that, the first terminal and the second terminal can be associated according to the token, thereby implementing multimedia capability data transmission of the first terminal and the second terminal. Therefore, the first terminal and the second terminal can perform multimedia data transmission through the server during the call and after the call ends.

图4为本发明实施例提供的另一种多媒体数据传输的方法的通信示意图。本发明实施例中涉及的第一终端和第二终端，无法获取与终端绑定的号码。需要说明的是，对于第一终端或第二终端，已经获取与终端绑定的号码的情况，也可以采用本实施例提供的多媒体数据传输的方法。FIG. 4 is a schematic diagram of communication of another method for transmitting multimedia data according to an embodiment of the present invention. The first terminal and the second terminal involved in the embodiment of the present invention cannot obtain the number bound to the terminal. It should be noted that, for the case that the first terminal or the second terminal has obtained the number bound to the terminal, the method for transmitting multimedia data provided by this embodiment may also be used.

本发明实施例包括步骤401-步骤404，对步骤401-404的描述，请参见上述实施例中对步骤201-204的描述，在此不作赘述。The embodiment of the present invention includes the steps 401 to 404. For the description of the steps 401-404, refer to the description of the steps 201-204 in the foregoing embodiment, and details are not described herein.

步骤405，第二终端向服务器发送令牌和第二终端的IP地址。Step 405: The second terminal sends the token and the IP address of the second terminal to the server.

示例性的，第一终端通过内网接入公网，将第一终端内网的IP地址转换为公网的IP地址后，发送给服务器。需要说明的是，公网是指普通电路交换网，即现在的网通，电信，铁通等架设的骨干及分支网络，公网是相对于内网而言的。通过内网上网的终端得到的IP地址是因特网上的保留地址，而通过公网上网的终端得到的IP地址是因特网的公用地址，是非保留的地址。通过公网上网的终端和因特网上的其他终端可随意互相访问，但通过内网上网的终端可能因设置有防火墙保护等原因，无法直接使用内网的IP地址与因特网上的其他终端进行通信。Exemplarily, the first terminal accesses the public network through the internal network, converts the IP address of the intranet of the first terminal into the IP address of the public network, and sends the IP address to the server. It should be noted that the public network refers to the common circuit-switched network, that is, the backbone and branch network of the current network communication, telecommunications, and railway, and the public network is relative to the internal network. The IP address obtained through the terminal of the intranet is the reserved address on the Internet, and the IP address obtained through the terminal of the public network is the public address of the Internet, which is a non-reserved address. The terminal on the public network and other terminals on the Internet can access each other at will, but the terminal through the intranet may not be able to directly communicate with other terminals on the Internet by using the IP address of the intranet due to the protection of the firewall.

示例性的，第二终端向服务器发送匹配业务请求消息，匹配业务请求消息包括令牌、第二终端的IP地址和第二终端的能力集。匹配业务请求消息用于请求与第一终端进行的多媒体能力信息匹配。其中，多媒体能力信息匹配包括：获取第一终端的能力集与第二终端的能力集的交集，或获取第一终端支持的SDP的参数等。Exemplarily, the second terminal sends a matching service request message to the server, where the matching service request message includes a token, an IP address of the second terminal, and a capability set of the second terminal. The matching service request message is used to request matching of the multimedia capability information performed by the first terminal.

The creating the multimedia service includes: sending, to the second terminal, parameters and multimedia data of the SDP supported by the first terminal, and receiving multimedia data from the second terminal.

示例性的，创建指令消息还包括第一终端的号码。Exemplarily, the create instruction message further includes the number of the first terminal.

步骤407，第一终端根据第二终端的IP地址向第二终端发送多媒体数据。Step 407: The first terminal sends the multimedia data to the second terminal according to the IP address of the second terminal.

需要说明的是，第二终端可以设置为允许接收未知IP地址发送的多媒体数据。在此种情况下，第二终端未接收第一终端的IP地址时，也可以接收第一终端发送的多媒体数据。同时，为了对终端进行安全防护，第二终端也可以设置为不允许接收未知IP地址发送的多媒体数据。在此种情况下，第二终端只有在已知第一终端的IP地址(如从服务器接收第一终端的IP地址)后，才能接收第一终端发送的多媒体数据，否则，将对自未知IP地址的第一终端发送的多媒体数据进行拦截，并执行丢弃处理。It should be noted that the second terminal may be set to allow receiving multimedia data transmitted by an unknown IP address. In this case, when the second terminal does not receive the IP address of the first terminal, the multimedia data sent by the first terminal may also be received. At the same time, in order to protect the terminal, the second terminal may also be set to not allow receiving multimedia data transmitted by an unknown IP address. In this case, the second terminal can receive the multimedia data sent by the first terminal only after knowing the IP address of the first terminal (such as receiving the IP address of the first terminal from the server), otherwise, the self-unknown IP will be The multimedia data sent by the first terminal of the address is intercepted, and the discarding process is performed.

示例性的，在步骤407之前，还可以包括：第一终端根据第二终端的IP地址向第二终端发送能力集查询请求，第二终端向第一终端发送第二终端的能力集。第一终端确定第一终端的能力集和第二终端的能力集的交集。For example, before the step 407, the method may further include: the first terminal sends a capability set query request to the second terminal according to the IP address of the second terminal, and the second terminal sends the capability set of the second terminal to the first terminal. The first terminal determines an intersection of the capability set of the first terminal and the capability set of the second terminal.

示例性的，在步骤407之前，还可以包括：第一终端根据第二终端的IP地址向第二终端发送SDP的参数查询请求，第二终端向第一终端发送第二终端支持的SDP的参数。第一终端确定第一终端支持的SDP的参数和第二终端支持的SDP的参数的交集。Exemplarily, before step 407, the method may further include: the first terminal sends a parameter query request of the SDP to the second terminal according to the IP address of the second terminal, and the second terminal sends the parameter of the SDP supported by the second terminal to the first terminal. . The first terminal determines an intersection of parameters of the SDP supported by the first terminal and parameters of the SDP supported by the second terminal.

示例性的，在步骤407中，还可以包括：第一终端根据第一终端的能力集和第二终端能力集的交集，以及第一终端支持的SDP的参数和第二终端支持的SDP的参数的交集，向第二终端发送多媒体数据。Exemplarily, in step 407, the method further includes: the first terminal according to the intersection of the capability set of the first terminal and the second terminal capability set, and the parameter of the SDP supported by the first terminal and the parameter of the SDP supported by the second terminal The intersection of the multimedia data is sent to the second terminal.

示例性的，在执行步骤407的同时，或之前，或之后，还可以包括：第二终端根据第一终端的IP地址向第一终端发送多媒体数据。Exemplarily, at the same time as, before, or after performing step 407, the method may further include: the second terminal transmitting the multimedia data to the first terminal according to the IP address of the first terminal.

当第一终端根据第二终端的IP地址，发送多媒体数据失败时，第一终端可以执行步骤408-414通过服务器中转，向第二终端发送多媒体数据。对步骤408-414的介绍可以参见上述对步骤208-214的描述，在此不作赘述。When the first terminal fails to send the multimedia data according to the IP address of the second terminal, the first terminal may perform the steps 408-414 to transfer the multimedia data to the second terminal by using the server. For a description of the steps 408-414, reference may be made to the description of the steps 208-214, which are not described herein.

需要说明的是，第二终端的IP地址可能是虚假的IP地址，例如，第二终端处于内网中，因内网和公网之间设置有具有安全保护作用的防火墙，当第二终端向服务器发送第二终端的IP地址时，防火墙对第二终端的IP地址进行处理，转化为虚假的IP地址，再发送给服务器，导致第一终端无法根据从服务器接收的第二终端的IP地址，将多媒体数据发送至第二终端。It should be noted that the IP address of the second terminal may be a fake IP address. For example, the second terminal is in the internal network, because a firewall with security protection is provided between the internal network and the public network, when the second terminal When the server sends the IP address of the second terminal, the firewall processes the IP address of the second terminal, converts it into a fake IP address, and sends it to the server, so that the first terminal cannot obtain the IP address of the second terminal received from the server. The multimedia data is transmitted to the second terminal.

本发明实施例提供的多媒体数据传输的方法，通过第一终端向第二终端发起呼叫时，从服务器取得令牌，并向第二终端发送该令牌，使服务器从第二终端接收该令牌后，能够根据该令牌关联第一终端和第二终端，并将第二终端的IP地址发送至第一终端，使第一终端和第二终端可以通过服务器中转，也可以不通过服务器中转，而直接进行多媒体数据的传输。因此，第一终端和第二终端可以在呼叫过程中和呼叫结束后，直接建立多媒体连接并进行多媒体业务。The method for transmitting multimedia data provided by the embodiment of the present invention, when the first terminal initiates a call to the second terminal, obtains a token from the server, and sends the token to the second terminal, so that the server receives the token from the second terminal. After the first terminal and the second terminal are associated with the token, the IP address of the second terminal is sent to the first terminal, so that the first terminal and the second terminal can be transited through the server, or can be transited through the server. Directly transfer multimedia data. Therefore, the first terminal and the second terminal can directly establish a multimedia connection and perform multimedia services during the call and after the call ends.

For another example, the first terminal in the embodiment of the present invention once used as the called terminal, and has obtained the number of the first terminal through the server. For another example, the operator of the SIM card installed in the first terminal is China Unicom, and China Unicom writes the number of the SIM card in the SIM card. Therefore, after the SIM card is installed in the first terminal, the first terminal can directly access the SIM card. The number of the SIM card is read in the card. Also for example, the first terminal after installing the SIM card supports 4G. When the first terminal initiates a call flow through the number of the SIM card, the mobile phone number needs to be registered. After the registration is successful, the 4G network server returns the number of the SIM card to the first terminal, so the first terminal can learn the first The number of the terminal. It should be noted that, in the case that the first terminal and the second terminal have obtained the number bound to the terminal, the multimedia data transmission method in this embodiment may also be used. As shown in FIG. 5, this embodiment includes:

本发明实施例提供的多媒体数据传输的方法，通过第一终端向第二终端发起呼叫时，向服务器发送第二终端的号码，服务器从第二终端接收第二终端号码和第二终端的IP地址后，将第二终端的IP地址发送至第一终端，使第一终端和第二终端可以通过服务器中转，也可以不通过服务器中转，而直接进行多媒体数据的传输。因此，第一终端和第二终端可以在呼叫过程中和呼叫结束后，直接建立多媒体连接并进行多媒体业务。The method for transmitting multimedia data provided by the embodiment of the present invention, when the first terminal initiates a call to the second terminal, sends the number of the second terminal to the server, and the server receives the second terminal number and the IP address of the second terminal from the second terminal. Then, the IP address of the second terminal is sent to the first terminal, so that the first terminal and the second terminal can be transited through the server, or the multimedia data can be directly transmitted without transiting through the server. Therefore, the first terminal and the second terminal can directly establish a multimedia connection and perform multimedia services during the call and after the call ends.

图7为本发明实施例提供的还一种多媒体能力发现的方法的通信示意图。本发明实施例中涉及的第一终端和第二终端，已经获取与终端绑定的号码。如图7所示，该实施例可以包括：FIG. 7 is a schematic diagram of communication of a method for discovering multimedia capabilities according to an embodiment of the present invention. The first terminal and the second terminal involved in the embodiment of the present invention have acquired the number bound to the terminal. As shown in FIG. 7, this embodiment may include:

步骤701，第一终端向服务器发送第一登录请求消息，第一登录请求消息包括第一终端的状态信息。Step 701: The first terminal sends a first login request message to the server, where the first login request message includes status information of the first terminal.

示例性的，第一终端与服务器建立第一连接(例如，HTTP连接)，并通过第一连接向服务器发送第一登录请求消息。Exemplarily, the first terminal establishes a first connection (eg, an HTTP connection) with the server, and sends a first login request message to the server through the first connection.

示例性的，第一终端与服务器建立心跳。需要说明的是，网络中的接收和发送数据都是使用操作***中的一对套接字(SOCKET，用于描述IP地址和端口)实现的。但是如果此套接字已经断开，那发送数据和接收数据的时候就一定会有问题。创建心跳机制的目的是判断此套接字是否可以使用。其中，心跳机制是一端通过向另一端定时发送一个自定义的结构体(心跳包)，让另一个端知道此端的套接字仍在使用，以确保连接的有效性的机制。例如，当一端向另一端发送心跳包后，在5分钟之内没有收到另一端的回复，则可以视为另一端的套接字不可用，即另一端已于此端断开连接。Exemplarily, the first terminal establishes a heartbeat with the server. It should be noted that the receiving and sending data in the network is implemented by using a pair of sockets (SOCKET, which is used to describe the IP address and port) in the operating system. But if the socket is disconnected, there must be problems when sending data and receiving data. The purpose of creating a heartbeat mechanism is to determine if this socket is available. The heartbeat mechanism is a mechanism in which one end sends a custom structure (heartbeat packet) to the other end, and the other end knows that the socket of the other end is still in use to ensure the validity of the connection. For example, when one end sends a heartbeat packet to the other end and does not receive a reply from the other end within 5 minutes, it can be considered that the other end of the socket is unavailable, that is, the other end has been disconnected at this end.

示例性的，第一登录请求消息包括第一终端的识别码和/或第一终端的号码。Exemplarily, the first login request message includes an identification code of the first terminal and/or a number of the first terminal.

步骤702，第二终端向服务器发送第二登录请求消息，第二登录请求消息包括第二终端的状态信息。Step 702: The second terminal sends a second login request message to the server, where the second login request message includes status information of the second terminal.

示例性的，第二终端与服务器建立第二连接(例如，HTTP连接)，并通过第二连接向服务器发送第二登录请求消息。Exemplarily, the second terminal establishes a second connection (eg, an HTTP connection) with the server, and sends a second login request message to the server through the second connection.

示例性的，第二登录请求消息包括第二终端的识别码和/或第一终端的号码。Exemplarily, the second login request message includes an identification code of the second terminal and/or a number of the first terminal.

需要说明的是，1)可以在执行步骤701的同时，之前或之后执行步骤702，本发明实施例对此不作限定。2)在执行步骤701和702之后，第一终端和第二终端之间可以订阅对方的状态信息。例如，第一终端向服务器发送查询第二终端状态信息的请求，服务器将查询到的第二终端的状态信息发送给第一终端。又例如，第一终端向服务器订阅第二终端的状态信息，服务器查询第二终端的状态信息，并通过短信等形式定期发送给第一终端。再例如，第一终端登录***应用，服务器自动查询第一终端和第二终端的状态信息，并通过***应用呈现给第一终端的用户。例如，第一终端登录***应用后，查看应用中的通讯录(如图8(a)所示)，可以实时查看其中某个用户支持的多媒体能力信息(如图8(b)所示，对于该用户支持的多媒体能力，相应的按钮显示为第一状态，如，白色；对于该用户不支持的多媒体能力，相应的按钮显示为第二状态，如，灰色。)。其中，终端的状态信息，包括终端是否开放了接收图片或语音的权限，是否支持视频通话等。需要说明的是，状态信息和多媒体能力集中的内容可以相同，也可以不同。均可以根据用户的偏好进行设置，同时也取决于终端和网络是否支持相应的多媒体能力。It should be noted that, the step 702 may be performed before or after the step 701 is performed, which is not limited by the embodiment of the present invention. 2) After performing steps 701 and 702, the first terminal and the second terminal can subscribe to the status information of the other party. For example, the first terminal sends a request for querying the second terminal status information to the server, and the server will The status information of the queried second terminal is sent to the first terminal. For another example, the first terminal subscribes to the server for status information of the second terminal, and the server queries the status information of the second terminal, and periodically sends the status information to the first terminal by using a short message or the like. For another example, the first terminal logs in to the system application, and the server automatically queries the status information of the first terminal and the second terminal, and presents the status information to the user of the first terminal by using the system application. For example, after the first terminal logs in to the system application, the address book in the application is viewed (as shown in FIG. 8(a)), and the multimedia capability information supported by one of the users can be viewed in real time (as shown in FIG. 8(b), The multimedia capability supported by the user, the corresponding button is displayed as a first state, such as white; for a multimedia capability that the user does not support, the corresponding button is displayed as a second state, such as gray. The status information of the terminal includes whether the terminal has the right to receive pictures or voices, whether to support video calls, and the like. It should be noted that the content of the status information and the multimedia capability set may be the same or different. They can all be set according to the user's preferences, and also depend on whether the terminal and the network support the corresponding multimedia capabilities.

可选的，步骤703，第一终端向服务器发送第一登录请求响应消息。Optionally, in step 703, the first terminal sends a first login request response message to the server.

可选的，步骤704，第二终端向服务器发送第二登录请求响应消息。示例性的，在步骤704之后，还可以包括，服务器建立第一终端的识别码与第一终端的对应关系，以及第二终端的识别码与第二终端的对应关系。Optionally, in step 704, the second terminal sends a second login request response message to the server. Exemplarily, after the step 704, the server may further include: the server establishes a correspondence between the identifier of the first terminal and the first terminal, and a correspondence between the identifier of the second terminal and the second terminal.

步骤705，第一终端向第二终端发送推送请求消息，该消息用于请求服务器生成令牌并建立令牌与第一终端的对应关系。需要说明的是，对步骤705的介绍可以参见上述实施例中对步骤201的描述，在此不作赘述。另外，推送请求消息中携带的能力集，可以与步骤701中第一终端的状态信息相同，也可以不同，具体可以根据用户设置、终端以及网络状态等进行调整。例如，第一终端的状态信息显示支持视频通话，当用户更换终端后，终端因无摄像头，所以不能支持视频通话，即第一终端的能力集中不包括支持视频通话。又例如，第一终端的状态信息显示支持位置共享，但因网络状态不稳定，第一终端无法读取用户位置信息，所以不支持位置共享，即第一终端的能力集中不包括支持位置共享。Step 705: The first terminal sends a push request message to the second terminal, where the message is used to request the server to generate a token and establish a correspondence between the token and the first terminal. It should be noted that the description of step 705 can be referred to the description of step 201 in the foregoing embodiment, and details are not described herein. In addition, the capability set carried in the push request message may be the same as or different from the state information of the first terminal in step 701, and may be adjusted according to user settings, terminals, and network status. For example, the status information of the first terminal is displayed to support the video call. When the user replaces the terminal, the terminal cannot support the video call because there is no camera, that is, the capability set of the first terminal does not include supporting the video call. For example, the status information of the first terminal is displayed to support the location sharing. However, because the network status is unstable, the first terminal cannot read the user location information, so the location sharing is not supported, that is, the capability aggregation of the first terminal does not include the support location sharing.

步骤706，服务器向第二终端发送唤醒消息，该消息包括令牌。Step 706: The server sends a wakeup message to the second terminal, where the message includes a token.

示例性的，服务器根据心跳机制向第二终端发送唤醒消息(例如，包括心跳包)，以判断服务器与第二终端是否仍处于连接状态。如果仍处于连接状态，则执行步骤707，如果连接已断开，则采用如图2所示的实施例中的方法，执行步骤202-步骤214。Exemplarily, the server sends a wake-up message (for example, including a heartbeat packet) to the second terminal according to the heartbeat mechanism to determine whether the server and the second terminal are still in a connected state. If it is still in the connected state, step 707 is performed, and if the connection has been disconnected, steps 202-214 are performed using the method in the embodiment shown in FIG. 2.

示例性的，唤醒消息包括第一终端的号码。Illustratively, the wake-up message includes the number of the first terminal.

步骤707，服务器从第二终端接收唤醒响应消息。Step 707: The server receives a wakeup response message from the second terminal.

步骤708，服务器向第一终端发送推送响应消息，该消息携带该令牌。Step 708: The server sends a push response message to the first terminal, where the message carries the token.

示例性的，推送响应消息携带后续推送(Massed)标识。后续推送标识用于指示第一终端在向第二终端发送的呼叫信令中，不需要传送令牌。Illustratively, the push response message carries a subsequent pushed identity. The subsequent push identifier is used to indicate that the first terminal does not need to transmit the token in the call signaling sent to the second terminal.

步骤709，第一终端向第二终端发送呼叫信令，呼叫信令包括改令牌。Step 709: The first terminal sends call signaling to the second terminal, where the call signaling includes changing the token.

示例性的，第一终端根据后续推送标识向第二终端发送呼叫信令。因呼叫信令中不需要传送令牌，所以也不需要使用UUS信元。UUS信元是运营商网络的信令中的信元，无需使用UUS信元可以使信令交互流程更加简洁。Exemplarily, the first terminal sends call signaling to the second terminal according to the subsequent push identifier. Since there is no need to transmit a token in call signaling, there is no need to use a UUS cell. The UUS cell is a cell in the signaling of the carrier network. The signaling interaction process can be simplified without using a UUS cell.

本发明实施里还包括步骤710-步骤720，对步骤710-步骤720的介绍可以如图2所示实施例中对步骤204-步骤214的介绍，在此不作赘述。The implementation of the present invention also includes the steps 710-step 720. The description of the steps 710-720 can be introduced in the embodiment shown in FIG. 2, and is not described here.
