Description
Technical field
The application relates to the technical field of IMS (IP Multimedia Subsystem, IP Multimedia System), particularly relates to a kind of sending method of instant message; A kind of dispensing device of instant message; A kind of method of reseptance of instant message, and, a kind of receiving system of instant message.
Background technology
Instant message is a kind of service that the non-storage of information ground that the sender is sent is transmitted to the recipient, is direct mutual between receiving terminal and transmitting terminal with the different instant messages that are of email message.
IMS (IP Multimedia Subsystem, IP Multimedia System) framework based on SIP (Session Initiation Protocol, conversation initialized protocol) is that instant message has made up a kind of good realization environment.In the IMS environment; The realization of instant message has two kinds of methods basically; A kind of MESSAGE (message) method that is based on SIP, another kind are based on the method that the IMS conversation mechanism is realized, they all are under the IMS ability framework of 3GPP TS22.228 definition, to realize.Under the MESSAGE of IMS method mechanism, the recipient can be in real time or is quasi real time received message.And under conversation-based mechanism, the message that the user receives generally is quasi real time, at first sets up session connection between recipient and the sender, can carry out the transmission of message then, and the content that transmits information can be text, image, audio or video.As shown in Figure 1, can message (messaging) be divided into two types according to the difference of the mode of sending: a kind of be instant message (instant messaging, IM), promptly message is sent the back and is passed to the recipient immediately, approaches real-time transmission; A kind of in addition then also insensitive to the delivery time of message, message is preserved by network and is sent in certain time subsequently, can be referred to as mailbox type messaging service (mailbox messaging).The application is primarily aimed at instant message and discusses.
Instant message can further be divided into two seed categories, and the instant message of non-conversation modes (Page-mode and Large Message-mode) and the instant message of conversation modes (Session-Mode) are as shown in Figure 2.The instant message of non-conversation modes adopts different patterns according to the size of sending message, and a kind of is the Page-mode pattern, and message is directly sent with the MESSAGE method of SIP; Another kind is a Large Message-mode pattern, and under this pattern, message size surpasses preset size, as surpassing 1300 bytes, carries out the transmission of message through MSRP (Message Session Relay Protocol, message session trunk protocol).The instant message of conversation modes then at first will be set up a session before transmitting message, use MSRP to carry out the transmission of message then.
In existing implementation, the method that a kind of instant message transmits is the indirect referencing method.The realization thought of indirect referencing method is when instant message that the terminal needs to comprise basic text message, accessory information and other extended field sends to one or more recipient; Use HTTP (hypertext transport protocol; HTTP) or other be stored on the station server based on transportation protocol of congestion control mechanism content topic request, this server is generally http server.And in request, insert a link, this link can be linked on the request content address of being stored, rather than puts into whole contents in the instant message.Send a message to receiving terminal then, adopt suitable mode to download content after the receiving terminal request of receiving from server.
Because http protocol is a stateless protocol, if subsequent treatment needs the information of front, then it must retransmit, and possibly cause each data volume that transmits that connects to increase like this, causes network congestion.On the other hand; Http protocol is connectionless agreement, and each connection needs client to send request earlier, receives response; Break off then and connecting; And a new TCP (Transmission Control Protocol, transmission control protocol) connection is all opened in http session at every turn, and this is to system and waste of network resources.

Embodiment
For above-mentioned purpose, the feature and advantage that make the application can be more obviously understandable, the application is done further detailed explanation below in conjunction with accompanying drawing and embodiment.
One of core concept of the application is, in instant message-sending method, constructs the generation of the similar one tree of process of message body.At first construct the leaf of tree, a plurality of leaves form one trees; This tree that generates then remakes the leaf into new tree, till all message are all encapsulated completion.In the method for reseptance of instant message, resolve the traversal of the similar one tree of process of message object.At first the root node from tree begins, and whole tree of the traversal of recurrence accomplished the parsing to instant message up to all nodes that traveled through tree successively.
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 may further comprise the steps:
Step 101 is obtained the instant message information that the user sends, and said instant message information comprises: message content body and message content types, and, recipient's information.
In reality, said message content body can comprise text message content, and/or, the annex message content.Said message content types can comprise audio types, and video type is sent the message report type, picture/mb-type, common Session Description Protocol type of message and text etc.Furthermore, said message content types can comprise the type that RFC2045, RFC2046 and RFC3862 agreement are supported.
As a kind of concrete application of the application embodiment, in the IMS network, the IMS terminal can use SIP MESSAGE to receive/transfer immediate news; Message content mainly comprises: the sip message head; Recipient's tabulation, professional extended field, message body text and message body annex.In the message content, except the sip message head, other part is a selectable items, is the part of message body.Because the needs of instant messaging; When sending out message for simultaneously a plurality of users like the terminal; Can have the message sink list in the message body; And whether need business information such as delivery report, and can in message body, carry a part of service related information, this part information is referred to as " professional extended field ".Instant messaging platform, the standard instant message of client except supporting that the IMS terminal is sent, instant message after all right support expanded.It is different that the difference of two kinds of message is mainly reflected in message body form partly, and the instant message form of standard is as shown in Figure 4.The instant message form of expansion is then as shown in Figure 5.
Can see that from Fig. 4 and Fig. 5 the message header of the instant message form of standard and the instant message form of expansion all is a SIP MESSAGE standard message head, different is the form of message body in the MESSAGE message.Carry basic information in the instant message of standard, message header and message body are not all had expansion; Instant message after the expansion is then expanded message physique formula.Its form adopts MIME (Multipurpose Internet Mail Extensions; The multipurpose internet mail expansion) nested CPIM (Common Presence and Instant Messaging; Public attending and the instant message standard) form, i.e. constituting of the instant message of expansion: sip message head+MIME message body (being the message body that message format adopts the MIME form).
Step 102 generates message header.
The instant message that the user sends through the terminal can be an object with the instant message total abstract, is called the MESSAGE message object, and 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.For example, under the IMS environment based on SIP, what the 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 the expansion is the sip message head of expansion.
Step 103 according to different message content types, is constructed basic messae body BODY objects with the message content body and the message content types of correspondence as two leaf nodes respectively.
In concrete the realization, 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; It is audio types; Video type is sent the message report type, picture/mb-type; Common Session Description Protocol type of message and text etc. are constructed basic messae body BODY objects with every kind in message message content types and corresponding message content body 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 (being the message body that message format adopts the CPIM form).Each message object comprises a message body BODY object as the member, and each basic messae body BODY object can comprise two members, message content types and message content body, and wherein each member all can be sky.
Particularly:
Message content types (Content-typeHeader): the type that can be used to define the described message body of message body BODY object.The message content types value is generally discrete type; Be the message content types of basic messae body BODY object, like audio types (audio), video type (video), send message report type, picture/mb-type (image), common Session Description Protocol type of message (sdp) and text (text) etc.
Message content body (BodyString): can be used for preserving the pairing message content string variable of message body BODY object message content types, can be text or binary message.
Step 104 according to said basic messae body BODY object complex structure message body BODY object, comprises in the said complex message body BODY object that characterizing the message content body is the leaf node of null value.
In a kind of preferred embodiment of the application, said instant message information can also comprise professional extend information, for example whether needs the business information of delivery report; Can comprise the message content attribute information in the said message header, said message content attribute information can be used to define the described message body type of complex message body BODY object; In this case, said step 104 can comprise following substep:
Substep S11, with said basic messae body BODY object and corresponding service extend information, message header information is as three leaf node structure message body key element BODYPART objects;
Substep S12, with said message body key element BODYPART object and message content attribute information complex structure message body BODY object, and interpolation sign message content body is the leaf node of null value in said complex message body BODY object.
In concrete the realization, a complex message body BODY object can comprise three leaves: the message content body, and message content attribute information and the tabulation of message body key element, wherein each member all can be sky.
Particularly:
Message content attribute information: the type that can be used to define the described message body of complex message body BODY object.The message content types value of complex message body BODY object can be for compound, like information type (message), and multicomponent type (multipart) etc.
Message content body (BodyString): being used for preserving the string variable of message body BODY object message content, 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 tabulation (BodyPartList): can be used for representing the tabulation of message body key element BODYPART object, its value can be sky, also can be the tabulation of a plurality of message body key element BODYPART objects compositions.
Wherein, Said message body key element BODYPART object can be used for the combination of describing message body BODY object and message header information, and wherein message header information (Header) can be the standard message head, also can be the message header of expansion; Said message body key element BODYPART object can comprise three members; Message header information, professional extend information and message body BODY object (can be basic messae body BODY object or complex message body BODY object), wherein each member all can be sky.
Message header information (OtherHeader): the information that is used to describe the message header of all kinds of expansions.
Professional extend information (Content-dispositionHeader): be used for message body is described, can indicate message body and whether represent to the user, and the processing mode of recipient can not identification message body type the time.
Message body BODY object (BodyObj): each message body key element BODYPART object can have a message body BODY object as the member.
