Description

A kind of method of transfer of data, system and equipment

Technical field

The present invention relates to the communications field, relate in particular to a kind of method, system and equipment of transfer of data.

Background technology

In present mobile data services implementation, the data interaction between mobile terminal side and the application server side has Pull mode and Push mode.

The Pull mode is meant: when the application program in being installed in portable terminal need be obtained business datum from the application corresponding server, portable terminal initiatively connected with server, and server is carried out data access, obtains the corresponding business data.The Pull mode is portable terminal initiatively obtains data from server a mode; Only be applicable to real-time is required lower data service reciprocal process, this be because, if the data that need be pushed to portable terminal are arranged in the server but portable terminal in time is not connected with server; Will cause data to push untimely problem; If the Pull mode is applied in the data service reciprocal process that real-time is had relatively high expectations, data delay will appear in mutual like data services such as mail, instant messagings.

The Push mode is meant: initiatively business datum is pushed to the mode of portable terminal by server, because it is the Push mode can push business datum to portable terminal in real time, therefore, better for the real-time effect that business datum pushes.The implementation of Push mode has multiple, comprising: short message Push mode (SMS Push), Multimedia Message Push mode (MMS Push), wireless application Push mode (WAP Push), the Internet Push mode (IP Push) and the Internet short message Push mode (EMN Push).

The implementation particular content of above-mentioned each Push mode is:

SMS Push and MMS Push are meant: server passes through the Push mode of the mode of short message or Multimedia Message to portable terminal propelling movement business datum, and the user can directly check the business datum in short message or the Multimedia Message through portable terminal.In the scheme of SMS Push and MMS Push; Server can receive network quality influence just to short message or the Multimedia Message that portable terminal pushes; When network quality was low, time delay can appear in the transmission of short message and Multimedia Message, influenced the real-time effect that business datum pushes; And the business datum that short message and Multimedia Message carry is the plaintext form, and also there is hidden danger in the fail safe of business datum; In addition; The user can only read business datum through portable terminal; And can not realize the information interaction with server through modes such as short message answers; And have only the software and hardware ability to support the portable terminal of Multimedia Message could support MMS Push, the hardware capabilities of portable terminal is had relatively high expectations, portable terminal is had restriction.

WAP Push is meant: server pushes the information that comprises link to portable terminal, and the corresponding business data are visited and obtained to portable terminal through the URL in the information (URL).In WAP Push scheme; Comprise server and send link and portable terminal through twice operation (in fact portable terminal is exactly the Pull operation through the operation of links and accesses business datum) of links and accesses business datum, the real-time of business datum propelling movement is had harmful effect to portable terminal.

EMN Push is meant: when server need be in the mailer propelling movement business datum of resting state in portable terminal; Send the proprietary short message that wakes up to portable terminal; Make mailer convert starting state into by resting state; After treating that mailer starts, set up long the connection, obtain business datum with mail server.In EMN Push scheme; Portable terminal does not break off long the connection after from mail server, obtaining business datum; But never just break off during the transmission of business datum in one section duration by mail server, in the duration that mail server is waited for, the not transmission of business datum between portable terminal and the mail server; But portable terminal and existing long the connection still between the mail server cause the system resource overhead of portable terminal big.

IP Push is meant: to an application program in the portable terminal; Provide the application server of business datum to keep an IP length to be connected with portable terminal for this application program; Because this long existence that connects; The application server said application program in portable terminal in real time pushes business datum, has overcome the delay problem of SMS Push, MMS Push and WAP Push, and mutual problem between SMS Push and MMS Push potential safety hazard, portable terminal and the server.

But; In IP Push scheme; If application program does not have operation or application program need not carry out under the situation of data interaction with application server; Portable terminal still continued to exist with long connection of the IP between the application server, had increased the resource overhead of portable terminal, caused portable terminal power consumption big; For solving the long resource overhead that brings that connects of IP; IP Push scheme has been done change, required to connect when IP is long to be connected the application program operation, when the application program off-duty, broken off; This change can make long connection of IP connect continually, break off again, still can increase the system resource overhead of portable terminal.

Simultaneously, to application server, towards portable terminal quantity very big, if application server respectively with each portable terminal in a corresponding application program set up a long connection, then the resource overhead of application server also can be very big.

Above-mentioned is to a kind of application program of installing in the portable terminal as far as IP Push scheme; The application program of a greater number has been installed in the present intelligent mobile terminal mostly; If all application programs in the portable terminal are all carried out IP Push scheme; When a plurality of application program promptly was installed in portable terminal, this portable terminal need be set up long the connection respectively with a plurality of application servers, and then portable terminal need be these long a large amount of system resources of distribution that connect; Cause the overhead of portable terminal excessive, even influence other professional normal operations of portable terminal.

Embodiment

Set up the resource that length takies when being connected in order to reduce portable terminal between local multiple application program of installing and the number of applications server; Obtain in the IP Push scheme transfer of data of high real-time between the portable terminal and application server simultaneously; The embodiment of the invention proposes a kind of new data transmission scheme; (Always Online Infrastructure AOI), is provided with gateway between portable terminal and application server to adopt always online mechanism; Set up long a connection between portable terminal and the gateway; Set up long a connection respectively between gateway and each application server, in up process, the upstream data message that the arbitrary application program in the portable terminal is sent all through with gateway between long a connection carry out uplink; In descending process, the downlink data message that application server sends to arbitrary portable terminal also through with gateway between long a connection carry out downlink transfer.For mobile terminal side, no matter the number of applications of installing in the portable terminal how, portable terminal only need for gateway between a long Resources allocation that is connected just can reach reception to the data high real-time; For the application server side, no matter the portable terminal quantity that this application server is served how, application server also only need for gateway between a long Resources allocation that is connected just can be in real time to the portable terminal propelling data.That is to say,, in data transmission procedure, both reduced, guaranteed the high real-time transfer of data between portable terminal and the application server again the resource occupation between portable terminal and the application server through the scheme of the embodiment of the invention.

The gateway that relates in the various embodiments of the present invention is meant always online gateway (the Always Online Gateway under the AOI mechanism; AOG); AOG can provide unified access point for using based on the long connection of mobile Internet, on the one hand, and as transfer of data between portable terminal and the network side and synchronous passage; On the other hand, as transfer of data between application server and the mobile terminal side and synchronous passage.

The portable terminal that relates in the various embodiments of the present invention is meant the portable terminal under the AOI mechanism, promptly have to be installed in each application program in the portable terminal carry out orderly management and and gateway between functions such as long connection management.Portable terminal under the AOI mechanism can be an installation and operation has the portable terminal of the AOI middleware of above-mentioned functions.

The application server that relates in the various embodiments of the present invention be meant with portable terminal in the application program of installing carry out the webserver of service data interaction.As: the instant messaging application program has been installed in the portable terminal, then, has carried out effective service data interaction between instant messaging application program needs and the instant communication server in order to guarantee the normal operation of instant messaging service.

The long connection of setting up in the various embodiments of the present invention is meant in a connection can send a plurality of packets continuously; During connecting maintenance; If there is not packet to send, need both sides to send out the connected mode of link keep-alive bag, as connecting to socket (Socket) long etc.

First long connection the between terminal and the gateway, can carry out uplink for the upstream data message that arbitrary application program in the portable terminal generates, and reception sends to the downlink data message of arbitrary application program in this terminal.

Second long connection the between application server and the gateway, can receive the upstream data message of arbitrary terminal transmission for application server, and transmit the upstream data message that this application server sends to arbitrary terminal.

Below in conjunction with Figure of description various embodiments of the present invention are elaborated.

Embodiment one:

As shown in Figure 1, up for carrying out in the embodiment of the invention one (Mobile Original, MO) the method step sketch map of transfer of data may further comprise the steps:

Step 101: portable terminal through with gateway between first long connection of setting up, to gateway transmission upstream data message.

The sign of carrying application server in the said upstream data message is represented the sign corresponding application server of the purpose recipient of this upstream data message for this application server.For example; After the mail applications generation of in portable terminal, installing sends to the upstream data message of mail server; Portable terminal is carried at the sign of mail server in this upstream data message, and through with gateway between first long the connection upstream data message was sent to gateway.Need to prove that no matter the upstream data message which kind of application program of installing in the portable terminal generates, portable terminal all is sent to gateway through said first long the connection.

Can safeguard a group key jointly between portable terminal and the gateway; When portable terminal when gateway sends upstream data message; Can utilize this key that upstream data message is encrypted; Simultaneously, (Transport Layer Sec TLS) encrypts the transmission course of upstream data message all right transport layer protocol safe in utilization of portable terminal.

Step 102: gateway is confirmed corresponding application server according to the sign that receives said application server.

Gateway can basis be deciphered the upstream data message that receives with the common key of safeguarding of portable terminal.

Step 103: gateway confirm with said application server between when setting up for second long the connection, grow through said second and to connect, upstream data message is sent to said application server.

Since gateway maybe with many application servers between set up for second long the connection respectively; Then gateway is when a certain application server sends upstream data message; At first check with this application server between whether available second long the connection was arranged; When having second available long the connection, through this second long connection sending upstream data message to application server.

Gateway also can be encrypted upstream data message when application server sends upstream data message, by application server the upstream data message that receives is deciphered.

In addition; Owing to can reduce the shared transfer resource of upstream data message through the data content in the upstream data message is compressed, be reduced in the data volume of transmitted over wireless networks, save the network bandwidth and reduce network delay; Therefore; In the upstream data message through first long the connection when transmitting, and through second long the connection when transmitting, can be according to the resource different (voice data, video data, text data etc.) of data content; Adopt rational compression algorithm to compress back transmission, the equipment (like gateway, application server) that receives the upstream data message after the compression can be separated press operation.

In addition; Since gateway towards the portable terminal One's name is legion; When a plurality of portable terminals send upstream data message to gateway simultaneously; Or same portable terminal is that different application programs is when sending a plurality of upstream data message, if the scarce capacity of gateway to handle all upstream data message simultaneously, is handled after then need sorting to these upstream data message successively.In the scheme of present embodiment, the mode that gateway sorts includes but not limited to following two kinds:

First kind of sortord: gateway just sorts according to the priority of business.Because the sign of all having carried application server in each upstream data message; Can confirm the pairing business of this upstream data message; Therefore, gateway can sort according to the height of service priority, the upstream data message that the priority treatment service priority is high.For example: also higher for the demanding professional corresponding priorities of real-time, require low professional corresponding priorities also lower for real-time.

Second kind of sortord: gateway just sorts according to the priority of portable terminal.Gateway can be set the priority height of portable terminal according to portable terminal present located wireless network environment.The portable terminal corresponding priorities is higher preferably for wireless network environment of living in, for the relatively poor portable terminal of wireless network environment of living in, makes wireless network environment poorer for fear of sending upstream data message, and is can corresponding priorities lower.

Technical scheme through above step 101～step 103 description; Gateway becomes the intermediary of real-time Transmission process between portable terminal and the application server; Demand side is not to the extensive application server of network side to make portable terminal, and only demand side carries out uplink to a gateway, also make simultaneously application server not demand side to a large amount of portable terminals; Demand side receives upstream data message to a gateway; Can effectively reduce portable terminal and application server and be the long resource overhead that distributes that is connected, simultaneously, according to the network architecture that first between portable terminal and the gateway longly is connected, gateway is connected with second length between the application server; Can realize business data transmission real-time between portable terminal and the application server, effectively improve real time of data transmission.

Concrete implementation in the face of above-mentioned steps 101～step 103 is elaborated down.

Before the uplink process of present embodiment one was carried out, portable terminal need be managed each application program that install this locality, therefore, before step 101, also had portable terminal internal control process, specifically comprised:

At first, the sign of the application program that mobile terminal records is installed in this locality, and gather the state information of each application program in real time, comprise that application program is in the information of running status, resting state or exit status.

Then, portable terminal also writes down the sign of each application program corresponding application server, is used for confirming upstream data message purpose recipient in the uplink process.

At last; After each item information record of the application program that portable terminal is installed this locality is accomplished; Whether there is application program need carry out up data interaction monitoring in real time; After having arbitrary application program to generate upstream data message, portable terminal is carried at the sign of this application program corresponding application server in the upstream data message of generation, and execution in step 101 then.

Through of the management of above-mentioned portable terminal to the application program of this locality installation, can effectively manage for the operation of local each application program, it is chaotic to avoid occurring the application program operation, even the problem of process collision.

Particularly; Local at portable terminal; An AOI middleware is arranged in the portable terminal, be used for each application program carry out orderly management and and gateway between functions such as long connection management, the local application program of installing of portable terminal can be directly connected in the AOI middleware through the long ways of connecting of Socket when running status; To the AOI middleware upstream data message waiting for transmission is provided, requires the AOI middleware to carry out real-time Transmission through first long the connection.

After portable terminal is accomplished the management to local application, can before step 101, in gateway, register and connect first and grow connection.The first long detailed process that connects is registered and set up to portable terminal in gateway as shown in Figure 2, comprises the steps:

Step 201: (Domain Name System DNS) initiates the gateway query requests to portable terminal, wherein carries first sign and second sign of portable terminal to domain name system.

First sign and second of portable terminal identify all be can unique expression portable terminal sign; Different is; First sign of portable terminal is the sign that portable terminal uses when in application server, register, and second to identify be the sign of mobile terminal registers in gateway.

For example, if said portable terminal is a mobile phone, then said first is designated phone number, and second is designated international mobile subscriber identity (IMSI).At this moment; Portable terminal with short message way when DNS initiates the gateway query requests; In short message, carry IMSI; Then the information that can from short message, carry of DNS is obtained second sign (IMSI) of portable terminal, through confirm first sign (phone number) of portable terminal through the source client information of short message.

Step 202:DNS stores first sign and second sign of said portable terminal.

Step 203:DNS returns the routing iinformation of this portable terminal home gateway to portable terminal.

In the scheme of present embodiment, can dispose many gateways in the network system, every gateway provides service for the portable terminal in certain zone.For example, every province disposes a gateway in the whole nation, for the provincial mobile terminal provides a Connection Service.Can be through manual type in the routing iinformation of each gateway of DNS storage inside and the coverage of each gateway service; When DNS receives the gateway query requests of a portable terminal initiation; Confirm the ownership place of this portable terminal according to the sign (first sign and second sign) of this portable terminal; And then inquire about the coverage of each gateway service, be the gateway that portable terminal is selected ownership.

The routing iinformation of the home gateway that DNS returns to portable terminal includes but not limited to the IP address of gateway.

Step 204: portable terminal is initiated register requirement according to the routing iinformation of the home gateway that receives to home gateway, and in this register requirement, carries second sign.

In this register requirement, can also carry the sign of the application program of installing in the portable terminal simultaneously.

Step 205: gateway is a mobile terminal registers.

Gateway is accomplished the registration to portable terminal, and is returned the message that succeeds in registration to portable terminal in the sign of the application program of log-on message of local memory mobile terminal (comprising the hour of log-on, second sign of portable terminal etc.) and mobile terminal administration.

In this step, after portable terminal was registered in gateway, gateway need be managed the registration portable terminal, comprises the management of following two aspects:

First aspect: to the management of information of mobile terminal, like management to hardware informations such as second sign of portable terminal, version number, operating system, producer, model, screen sizes.

Second aspect: to the management of mobile terminal service, like management of information such as class of business that portable terminal is supported, Business Names.

Step 206: portable terminal set up with gateway between first long the connection.

After this, when having arbitrary application program to initiate upstream data message in the portable terminal, portable terminal is through this first long gateway that upstream data message is sent to ownership that connects.

Gateway wants execution in step 103 that this upstream data message is sent to application server after the upstream data message that receives from portable terminal.But because application server and a large amount of portable terminal of behavior provide professional, therefore, portable terminal carries second sign in upstream data message, hopes that application server can know the portable terminal that sends this upstream data message.But what use when portable terminal is registered in application server is first sign; And when registration uses in gateway is second sign; Therefore, issue application server if gateway directly is carried at second sign in the upstream data message, then application server possibly can't be discerned; In order to overcome this problem; The step 103 of this enforcement is when operation, and gateway is according to second sign of portable terminal, and first of this portable terminal of Directory Enquiries identifies from DNS; And first sign of this portable terminal is carried in the upstream data message and sends to application server, make application server can obtain the transmission portable terminal of this upstream data message according to first sign of upstream data message.

Consider and in network system, disposed many gateways; Portable terminal can transmit according to long connection of first between portable terminal and the home gateway to the upstream data message of the gateway transmission of its ownership; But the application server of the destination of this upstream data transmission of messages not necessarily set up for second long the connection with the gateway of portable terminal ownership; Therefore; In the time of need between gateway and each application server, setting up for second long the connection, in DNS storage gateway with set up second with this gateway respectively and grow first corresponding relation of the application server that is connected so that inquire about the gateway that application server belonged to.

Be applied in the step 103 of present embodiment, there are following two kinds of situation in gateway to the process that application server sends uplink message:

First kind of situation: gateway is through the inquiry to long connectivity port; Confirm with upstream data message in the sign corresponding application server of application server set up second and grow and be connected; The source end (portable terminal) that is upstream data message is all set up long the connection with same gateway with destination (application server), and this upstream data message can directly be transmitted.

Second kind of situation: gateway confirm not with upstream data message in the sign corresponding application server of application server set up for second long the connection; Promptly this gateway is not the gateway of this application server ownership; Then gateway is inquired about DNS; Find other gateways that this application server belongs to (distinguish for the gateway of the upstream data message of sending with mobile terminal receive, the gateway with the application server ownership is referred to as other gateways) here, and after said upstream data message sent to said other gateways; Because said other gateways are destination application server home gateways; Be connected with second length is arranged between this application server, therefore, said other gateways send to application server with upstream data message through second long the connection.

In addition, after step 103 was carried out, gateway can also write down this transmitting uplink data process log information, and produced ticket.Here the ticket that produces also is different from conventional ticket, this be because: in the uplink process of portable terminal, can use the scheme of the embodiment of the invention one; Also can use existing other schemes; In order to reduce change, in the scheme of present embodiment one, the CP that adopts present embodiment one scheme, the flow of SP are settled accounts by the ticket that gateway produces to the ticket generating mode of present routine; Be used with conventional ticket, confirm the expense that in each uplink process, produces.

Embodiment two:

The scheme of the embodiment of the invention one; Can between portable terminal and application server, be connected the transmission of controlling signaling and data through being connected with second length with first length of gateway; Distinguishingly, if the data volume of data to be transmitted very big (like the annex of the big quantity of carrying in the mail), with mass data with control signaling and a spot of data simultaneously through long a connection when transmitting; May influence the correct transmission of control signaling; Therefore, present embodiment two is set up interim long the connection for the data of big data quantity and is carried out data penetration transmission on the basis of embodiment one.

The scheme of present embodiment two is following:

The first step: set up for first long the connection between portable terminal and the home gateway, set up second between application server and the home gateway and grow and be connected.

Second step: portable terminal is through the first long uplink upstream data message that connects, and gateway sends to application server with this upstream data message through second long the connection.

In the scheme of present embodiment two, portable terminal is identical with embodiment one to the mode of application server uplink upstream data message.

The 3rd step: portable terminal sends proxy requests to gateway, carries the sign of application server and the data volume of data to be transmitted in the said proxy requests.

In the scheme of present embodiment, gateway has the ability of support from agency (Proxy) request of portable terminal.

The 4th step: gateway judges whether said data volume reaches threshold value, if then carried out for the 5th step; Otherwise, require portable terminal that data to be transmitted was transmitted through first long the connection.

The 5th step: gateway judges whether to set up for second long the connection with corresponding application server according to the sign of the application server that carries in the proxy requests:

If; Gateway is set up interim long the connection respectively with between said portable terminal and the corresponding application server; Through with portable terminal between the interim long said data to be transmitted that receives from portable terminal that is connected, and discharge after the end of transmission with portable terminal between interim length be connected, and; With said data to be transmitted through with application server between interim longly is connected transparent transmission to application server, and discharge after the end of transmission with application server between interim length be connected.

Otherwise; Gateway is inquired about from DNS with said corresponding application server and is set up second long other gateways that are connected; And set up interim long the connection with said portable terminal and said other gateways respectively; Through with portable terminal between the interim long said data to be transmitted that receives from portable terminal that is connected, and discharge after the end of transmission with portable terminal between interim length be connected, and; With said data to be transmitted through with said other gateways between interim longly is connected transparent transmission to other gateways, and discharge after the end of transmission with said other gateways between interim length be connected.

Scheme through the embodiment of the invention two; Set up interim long the connection separately to the data of big data quantity between portable terminal, gateway and the application server, gateway is given application server or other gateways with the data penetration transmission of the big data quantity that portable terminal sends, and data is not carried out the protocol encapsulation and the control of AOP layer; At this moment; Gateway is equivalent to the Transparent Proxy between portable terminal and the application server, has avoided the transmission of big data quantity that other transmission of controlling signalings are impacted, simultaneously; Will be released after being connected the end of transmission temporarily, farthest practice thrift the resource of portable terminal and application server.In addition, because interim long connection of Proxy form do not have heartbeat detection, in particular cases (cut off the power supply) like portable terminal at some; Gateway will not receive the chain rupture message; At this moment, gateway will safeguard always with portable terminal between interim long the connection, cause the wasting of resources of gateway.Therefore, gateway can be periodically to portable terminal between interim long the connection carry out this and can detect, whether inquiry has transfer of data, if in one continuous period, not interim long the connection do not have transfer of data, then discharging should interim long connection.Gateway is similar with portable terminal with the interim long dispose procedure that is connected between the application server.

Embodiment three:

The embodiment of the invention three also provides a kind of downlink data transmitting method, and is as shown in Figure 3, said method comprising the steps of:

Step 301: application server through with gateway between second long connection of setting up to gateway transmission downlink data message.

In the scheme of present embodiment; Having set up one second length between the gateway of each application server and ownership is connected; When application server need be when any portable terminal of being served pushes downlink data message, through this second long connection downlink data message being sent to gateway.

The sign of in said downlink data message, having carried portable terminal; Description according to embodiment one and embodiment two; What the sign of portable terminal involved in the present invention had comprised when portable terminal is registered that first sign used and portable terminal use when in gateway, register in application server second identifies; Therefore; The mobile terminal identification of application server for storage is first sign (like phone number) of portable terminal, and then application server is carried at downlink data message with first sign of portable terminal, is used to indicate gateway to send this downlink data message to the corresponding mobile terminal.

Further; Because this step is application server initiatively pushes a process from downlink data message to portable terminal; At this moment, portable terminal possibly set up first long connection the, the downlink data receiving message in real time with gateway; Possibly not set up first long connection the, the downlink data receiving message in real time with gateway yet; Simultaneously; The application program that needs in the portable terminal to receive this downlink data message possibly started from operation, dormancy or withdraw from this three kinds of states; Therefore; Even portable terminal receives this downlink data message, the application program that is in dormancy or exit status can not in time receive and handle downlink data message.Therefore; Application server is provided with a flag bit in sending to the downlink data message of gateway; If the mark position is 1, represent that the real-time of this downlink data message is high, application server hopes that this downlink data message is in time received by corresponding application; If this application program is in dormancy or exit status, then require portable terminal to wake this application program up; If the mark position is 0, represent that the real-time of this downlink data message is low, if this application program is in dormancy or exit status, then portable terminal is redispatched to this application program after can waiting for the corresponding application operation.

Step 302: gateway is confirmed corresponding mobile terminal according to first sign of the portable terminal that carries in the downlink data message.

Similar with embodiment one; Portable terminal in the present embodiment is also registered in gateway; First of the memory mobile terminal sign and second sign among the DNS; Also stored gateway and first corresponding relation of setting up the second long application server that is connected respectively with this gateway simultaneously, and second corresponding relation between second sign and this portable terminal home gateway sign.DNS can to user and gateway provide friendly graphical interfaces with support to canned data increase, deletion, modification and query manipulation, and canned data in time comes into force and can use.
