Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Be illustrated in figure 1 the workflow diagram of the information push method of a kind of intelligent mobile terminal of the present invention, comprise:
Step S101, comprising: push management server and receive the content server registration request of content server, records and preserves the information of content server, setting up logical session with content server;
Step S102, comprise: client sends to propelling movement management server and sets up logical session request, push management server according to the loading condition of each carrying server, one is selected to carry server and client associate, and the information of carrying server is returned client, client, according to the information of received carrying server, sends to carrying server and sets up logical session request, carrying server is that client sets up public network address and port numbers, sets up logical session with client;
Step S103, comprise: the PUSH message that the content server that propelling movement management server receives built vertical logical session sends, described PUSH message comprises targets of messages recipient characteristic sum and pushes content, and propelling movement content is forwarded to the carrying server associated by the client meeting targets of messages recipient feature by propelling movement management server;
Step S104, comprising: propelling movement content is sent to client by carrying server.
Content server is registered in step S101 in propelling movement management server, and client then carries out twice registration.The present invention adopts the mode of twice registration, and client only needs to know the address information pushing management server, is then that it distributes suitable carrying server by propelling movement management server, and re-starts registration to set up final logical session.After establishing logical session, then in step S104, the propelling movement content forwarded by propelling movement management server in step S103 is pushed in client by carrying server.
Client of the present invention has carried out twice registration, namely first after the registration of propelling movement management server, then registers to carrying server.Owing to adopting twice registration, therefore pushing management server can carry out load balancing distribution well, and the propelling movement improving client is experienced.
Wherein in an embodiment, described step S102, specifically comprises:
Client to push management server send comprise session label information set up logical session request, push management server to verify client, if the verification passes, then push management server according to the loading condition of each carrying server, the information of a carrying server is returned client, and the logical session that recording conversation identification information identifies is legitimate conversation, if checking is not passed through, return mistake and respond;
Client, according to the information of received current carrying server, sends to current carrying server and sets up logical session request;
Receive the carrying server comprising the logical session request of setting up of session label information that client sends, whether legal about the logical session of session label information to the inquiry of propelling movement management server, after to confirm about the logical session of session label information from management server be legitimate conversation, for client sets up public network address and port numbers, set up logical session with client;
Client to push that management server sends to set up session label information included by logical session request and client consistent to carrying the session label information set up included by logical session request that server sends.
In the present embodiment, be responsible for verifying client by propelling movement management server, as long as be verified, then the logical session of correspondence can be designated legitimate conversation.Due to client to push that management server sends to set up session label information included by logical session request and client consistent to carrying the session label information set up included by logical session request that server sends, therefore whether it only needs inquiry propelling movement management server legal about the logical session of session label information to carry server, namely carry server without the need to verifying client, thus decrease the communication overhead between client and carrying server.
Wherein in an embodiment, client is TCP bag to the logical session request of setting up pushing management server transmission, and client is UDP bag to the logical session request of setting up that carrying server sends.
TCP (TransmissionControlProtocol) bag and transmission control protocol bag, UDP (UserDatagramProtocol) bag and User Datagram Protoco (UDP) bag.
Client is only set up once to the logical session request of setting up pushing management server transmission, therefore adopts TCP bag to carry out connecting to guarantee quality.And client needs long-term foundation to the logical session request of setting up that carrying server sends, and need to continue to send message, in order to reduce the expense that message sends, and process disconnection test problems more flexibly, therefore the present embodiment adopts UDP to it, reduces the communication overhead between client and carrying server further.
Wherein in an embodiment, also comprise: heartbeat maintains step, described heartbeat maintains step, comprising:
Client sends heartbeat packet to carrying server according to the heartbeat time interval preset, described heartbeat packet is binary system bag, comprise: the logical session for identifying the logical session that client is set up with carrying server identifies, and next heartbeat maximum duration interval;
After carrying server receives the heartbeat packet of client, logical session mark and next heartbeat maximum duration interval are associated and preserves, check whether public network address and the port numbers of client there occurs change, if the public network address of client or port numbers change, then the public network address changed or the port numbers changed being attached to client responds in bag, if exist between the double heartbeat packet receiving client transmission and push failed bag, then in client response bag, arrange propelling movement unsuccessfully to identify, after having built client response bag, client is responded bag and sends to client,
Client, after receiving client response bag, makes the following judgment: if public network address there occurs change, then client readjusts heartbeat time interval to the maximum preset; If public network address does not change, and port there occurs change or pushes unsuccessfully to identify and is set up number of times continuously and exceedes default failed read-around ratio threshold value, if then now eartbeat interval not yet reaches default eartbeat interval time threshold values, then client shortens eartbeat interval, if now eartbeat interval reaches default eartbeat interval time threshold values, then no longer shorten eartbeat interval;
When behind the maximum duration interval of next heartbeat arriving the association of logical session mark, carrying server does not receive the heartbeat packet that the client corresponding to identifying with logical session is sent, then record corresponding logical session and lose heartbeat, if the number of times that logical session loses heartbeat continuously exceedes preset times, then stop corresponding logical session.
Wherein, client is after receiving client response bag, and the judgement carried out, is specially:
If public network address there occurs change, then represent that user access network may have occurred change, client readjusts heartbeat time interval to default maximum, starts a new eartbeat interval adjustment cycle;
If just port there occurs change or pushes unsuccessfully mark and is set up number of times and continues to exceed threshold value, then represent that the eartbeat interval of user is possible excessive.If now eartbeat interval not yet reaches pre-set threshold value, then client shortens eartbeat interval, otherwise no longer shortens eartbeat interval, and it is a quasi real time model by poll acquisition message that this Communication Model is changed in quality.
Therefore, when network condition worsens, server by message real time propelling movement to client, but when client sends heartbeat packet at every turn, can not be responded by heartbeat, notice client cancels breath, so, message model has been degenerated to polling mode, and the present embodiment can be in this case, shorten polling interval, approximate completes message real time propelling movement.
The heartbeat packet of the present embodiment adopts binary system bag, thus reduces communication overhead further.Meanwhile, by heartbeat mechanism, maintain the logical session between client and carrying server.
Wherein in an embodiment, described step S104, specifically comprises:
Carrying server is that each propelling movement content sets up affairs;
Affairs enter into init state after setting up, and the transport layer submitting to carrying server adopts UDP bag to send to client, and affairs enter into transmission state;
If transport layer completes transmission transaction, then affairs enter the state of being sent completely, if transport layer sends affairs failure, then affairs are moved to final state;
Under affairs enter the state of being sent completely, start timer, before timing terminates, receive client respond, then affairs are moved to committed state, respond if timing confiscates client before terminating, and sending times does not reach the upper limit, then affairs resubmited and adopt UDP bag to send to transport layer to client, affairs return state in transmission, respond if timing confiscates client before terminating, and sending times reaches the upper limit, then affairs enter halted state;
Under affairs enter halted state, if the life cycle pushing content arrives, then affairs move to final state, and the life cycle pushing content is carried in the PUSH message of propelling movement management server transmission by content server, and is forwarded to carrying server by propelling movement management server;
Under affairs enter halted state, if having received heartbeat packet, be 0 with regard to reset sending times, affairs resubmited and adopt UDP bag to send to transport layer to client, affairs return state in transmission.
