Description
Technical field
The application relates to IMS(IPMultimediaSubsystem, IP Multimedia System) technical field, particularly relate to a kind of sending method of instant message, a kind of dispensing device of instant message, a method of reseptance for instant message, and, a kind of receiving system of instant message.
Background technology
Instant message be the information non-memory that sender is sent be transmitted to the one service of recipient, be that instant message is directly mutual between receiving terminal and transmitting terminal from the different of email message.
Based on SIP(SessionInitiationProtocol, conversation initialized protocol) IMS(IPMultimediaSubsystem, IP Multimedia System) framework is that instant message constructs one and well realizes environment.In the ims environment, the realization of instant message has two kinds of methods substantially, the MESSAGE(message based on SIP) method, another kind is the method realized based on IMS conversation mechanism, and they are all realize under the IMS ability framework of 3GPPTS22.228 definition.Under the MESSAGE method mechanism of IMS, recipient can receive message in real time or quasi real time.And under conversation-based mechanism, the message that user receives is generally quasi real time, first set up session connection between recipient and sender, then can carry out the transmission of message, the content transmitting information can be text, image, audio or video.As shown in Figure 1, message (messaging) can be divided into two types by the difference according to the mode of sending: one is instant message (instantmessaging, IM), and namely message is immediately passed to recipient, close to real-time transmission after sending; Another is then insensitive to delivery time of message, and message is preserved by network and sent in certain time subsequently, can be referred to as mailbox type messaging service (mailboxmessaging).The application discusses mainly for instant message.
Instant message can be further divided into two seed categories, the instant message of non-session pattern (Page-mode and LargeMessage-mode) and the instant message of conversation modes (Session-Mode), as shown in Figure 2.The instant message of non-session pattern adopts different patterns according to the size sending message, and one is Page-mode pattern, and message directly sends with the MESSAGE method of SIP; Another kind is LargeMessage-mode pattern, and in this mode, message size exceedes default size, as more than 1300 bytes, by MSRP(MessageSessionRelayProtocol, message session trunk protocol) carry out the transmission of message.First the instant message of conversation modes then will set up a session before transmission message, then used MSRP to carry out the transmission of message.
In existing implementation, a kind of method that instant message transmits is indirect referencing method.The thought that realizes of indirect referencing method is when terminal needs the instant message comprising basic text message, accessory information and other extended field to be sent to one or more recipient, use HTTP(hypertexttransportprotocol, HTTP) or other transportation protocol based on congestion control mechanism the content topic of request is stored on a station server, this server is generally http server.And insert a link in the request, this link can be linked on stored request content address, instead of whole content is put in instant message.Then send a message to receiving terminal, receiving terminal adopts appropriate ways from downloading contents server after receiving request.
Because http protocol is stateless protocol, if subsequent treatment needs information above, then it must retransmit, and each data volume transmitted that connects may be caused like this to increase, cause network congestion.On the other hand, http protocol is connectionless agreement, each connection needs client first to send request, receive response, then disconnect, and a new TCP(TransmissionControlProtocol is all opened in each http session, transmission control protocol) connect, this is the waste to System and Network resource.
The technical problem needing those skilled in the art urgently to solve at present is exactly: when the instant message comprising basic text message, accessory information and other extended field is sent to one or more recipient, how to reduce network congestion, save the transmission that System and Network resource realizes instant message.

One of core concept of the application is, in the sending method of instant message, and the generation of the similar one tree of process of structure message body.First construct the leaf of tree, multiple leaf forms one tree; Then this tree generated is re-used as the leaf of new tree, until all message all encapsulated.In the method for reseptance of instant message, resolve the traversal of the similar one tree of process of message object.First, from the root node of tree, whole of the traversal of recurrence tree successively, until all nodes having traveled through tree complete the parsing to instant message.
With reference to Fig. 3, show the flow chart of steps of the sending method embodiment 1 of a kind of instant message of the application, specifically can comprise the following steps:
Step 101, obtain the instant message information that user sends, described instant message information comprises: message content body and message content types, and, recipient's information.
In practice, described message content body can comprise text message content, and/or, annex message content.Described message content types can comprise audio types, video type, sends message report type, picture/mb-type, common Session Description Protocol type of message and text type etc.Furthermore, described message content types can comprise the type that RFC2045, RFC2046 and RFC3862 agreement is supported.
As a kind of embody rule of the embodiment of the present application, in the ims network, IMS terminal can use SIPMESSAGE to receive/transfer immediate news, message content mainly comprises: sip message head, recipient's list, operation expanding field, message body text and message body annex.In message content, except sip message head, other part is selectable items, is the part of message body.Due to the needs of instant messaging, as terminal simultaneously give multiple user send out message time, can with message sink list in message body, and the need of business information such as delivery reports, can carry a part of service related information in message body, this part information is referred to as " operation expanding field ".The standard instant message that instant messaging platform, client send except supporting IMS terminal, can also support to expand rear instant message.The form that the difference of two kinds of message is mainly reflected in message body portion is different, and the instant message form of standard as shown in Figure 4.The instant message form of expansion then as shown in Figure 5.
Can see from Fig. 4 and Fig. 5, the message header of the instant message form of standard and the instant message form of expansion is all SIPMESSAGE standard message head, unlike the form of message body in MESSAGE message.Carry basic information in the instant message of standard, message header and message body are not all expanded; Instant message after expansion is then expanded message physique formula.Its form adopts MIME(MultipurposeInternetMailExtensions, multipurpose internet mail is expanded) nested CPIM(CommonPresenceandInstantMessaging, publicly to attend and instant message specification) form, the formation of the instant message namely expanded is: sip message head+MIME message body (namely message format adopts the message body of MIME form).
Step 102, generating messages head.
The instant message that user is sent by terminal, can be an object by instant message total abstract, be called MESSAGE message object, this message object can comprise message header and message body.In the preferred a kind of embodiment of the application, message header can be the message header of standard, also can be the message header of expansion.Such as, based under the IMS environment of SIP, what instant messaging platform generated for the instant message of standard is the sip message head of standard, and what generate for the instant message after expansion is the sip message head of expansion.
Step 103, according to different message content types, constructs basic messae body BODY objects using the message content body of correspondence and message content types as two leaf nodes respectively.
In specific implementation, a basic messae body BODY object can comprise two leaves, and one is message content, and one is message content types.According to different message content types, i.e. audio types, video type, send message report type, picture/mb-type, common Session Description Protocol type of message and text type etc., construct basic messae body BODY objects using the message content body of often kind of message content types in message and correspondence thereof as two leaf nodes respectively.
Basic messae body BODY object can be used for representing a complete message body, can be complete MIME message body, also can be a complete CPIM message body (i.e. the message body of message format employing CPIM form).Each message object comprises a message body BODY object as member, and each basic messae body BODY object can comprise two members, message content types and message content body, and wherein each member can be all empty.
Specifically:
Message content types (Content-typeHeader): the type that may be used for the message body defined described by message body BODY object.Message content types value is generally discrete type, the i.e. message content types of basic messae body BODY object, as audio types (audio), video type (video), sends message report type, picture/mb-type (image), common Session Description Protocol type of message (sdp) and text type (text) etc.
Message content body (BodyString): may be used for preserving the message content string variable in message body BODY object corresponding to message content types, can be text or binary message.
Step 104, according to described basic messae body BODY object formation complex message body BODY object, it is the leaf node of null value that described complex message body BODY object comprises sign message content body.
In a preferred embodiment of the present application, described instant message information can also comprise operation expanding information, such as, the need of the business information of delivery report; Can comprise message content properties information in described message header, described message content properties information may be used for defining the message body type described by complex message body BODY object; In this case, described step 104 can comprise following sub-step:
Sub-step S11, by the operation expanding information of described basic messae body BODY object and correspondence, message header information is as three leaf nodes structure message body key element BODYPART objects;
Sub-step S12, by described message body key element BODYPART object and message content properties information structuring complex message body BODY object, and interpolation sign message content body is the leaf node of null value in described complex message body BODY object.
In specific implementation, a complex message body BODY object can comprise three leaves: message content body, message content properties information and the list of message body key element, and wherein each member can be all empty.
Specifically:
Message content properties information: the type that may be used for the message body defined described by complex message body BODY object.The message content types value of complex message body BODY object can be compound, as information type (message), and multicomponent type (multipart) etc.
Message content body (BodyString): for preserving the string variable of message content in message body BODY object, can be text or binary message.And for complex message body BODY object, the value of its message content body is empty.
Message body key element list (BodyPartList): the list that can be used for representing message body key element BODYPART object, its value can be empty, also can be the list that multiple message body key element BODYPART object forms.
Wherein, described message body key element BODYPART object can be used for the combination of describing message body BODY object and message header information, wherein message header information (Header) can be standard message head, also can be the message header of expansion, described message body key element BODYPART object can comprise three members, message header information, operation expanding information and message body BODY object (can be basic messae body BODY object or complex message body BODY object), wherein each member can be all empty.
Message header information (OtherHeader): for describing the information of the message header of all kinds of expansion.
Operation expanding information (Content-dispositionHeader): for being described message body, can indicate message body and whether be presented to user, and recipient can not identification message body type time processing mode.
Message body BODY object (BodyObj): each message body key element BODYPART object can have a message body BODY object as member.
Described message header and complex message body BODY object encapsulation are message object by step 105.
