Further, the embodiment of the present invention two based in above-described embodiment one introduce based between heterogeneous networkDifferent links carry out the system of transfer of data, to insert two physics of TD-SCDMA and WLAN in terminalNetwork interface card is example, elaborates the method for carrying out transfer of data based on heterogeneous networks link between heterogeneous network, asShown in Fig. 2, detailed process is as follows:
Based on the system architecture in above-described embodiment one, in up-link:
Step 201, link management equipment receiving terminal is based on Microsoft Loopback Adapter address, to the report of network side transmissionLiterary composition. For example, terminal is based on Microsoft Loopback Adapter address, and access from a certain webpage to network side transmission that need to access pleaseAsk message.
Step 202, link management equipment terminal insert two network interface cards (TD-SCDMA network interface card andWLAN network interface card) distinguish in corresponding communication network link, select one or more of communication network links to useWith message transmission. Wherein, to can be, but not limited to according to load balancing principle be waiting for transmission to link management equipmentMessage is selected a communication network link. Or according to the size of the message waiting for transmission receiving, comprehensively examineThe load condition of considering communication network link is that message waiting for transmission is selected a communication network link.
Further, to message waiting for transmission, if the Capacity Ratio of this message is larger, using terminal managementEquipment is initially communication network link that this message waiting for transmission selects while transmitting, transmission a period of time withAfter, if this selecteed communication network link load is larger, can not continue again to transmit this message time,Now, link management equipment can be selected another communication network link for remaining message, treats by remainderThe message of transmission is switched to and on another communication network link of selection, continues transmission. For example, receive terminalThe message capacity of sending based on Microsoft Loopback Adapter address is 50M, is the communication network chain that this message is selected when beginningRoad is the communication network link that TD-SCDMA network interface card is corresponding, and using, TD-SCDMA network interface card is correspondingCommunication network link by this message transmissions after 20M, due to communication network corresponding to TD-SCDMA network interface cardNetwork link load is larger, and now link management equipment, by remaining 30M message, is switched to WLAN netBlocking corresponding communication network link trunking resumes defeated. Like this, can realize in message transmission procedure, needWhile communicating network link switching, terminal does not need to regain the communication network link correspondence that will be switched toAddress information and re-establish access route, then message transmission again, can realize at isomerization networkBetween different transmission links on carry out seamless switching, and, in handoff procedure, there will not be message to loseThe problems such as bag, network delay.
Further, to message waiting for transmission, if the Capacity Ratio of this message is larger, using terminal managementEquipment is initially communication network link that this message waiting for transmission selects while transmitting, can also be according to messageCapacity, and consider the performance of the communication network link that multiple network interface cards of being inserted in terminal are corresponding, willThe message processing that splits, then selects suitable communication network link for the message after splitting, and then uses choosingThe communication network link transmission message of selecting out. For example, receive the report that terminal is sent based on Microsoft Loopback Adapter addressLiterary composition capacity is 50M, now, has two network interface cards in terminal, TD-SCDMA network interface card and WLAN network interface card,Communication network link corresponding to two network interface cards, can be according to two communications that network interface card is corresponding all in upstateThe actual loading situation of network link, splits message, as used communication corresponding to TD-SCDMA network interface cardNetwork link transmits the 20M capacity of this message, uses communication network link transmission corresponding to WLAN network interface cardThe 30M capacity of this message remainder. Like this, can improve preferably in the transmitting procedure of message, to insertingEnter the efficiency of transmission of the communication network link that network interface card in terminal is corresponding, improve network quality and promote userPerceptibility.
Step 203, link management equipment is changed the Microsoft Loopback Adapter address as source address in message,Be converted to the NIC address of the network interface card that the communication network link of selection is corresponding. Wherein, NIC address can but notBe limited to the MAC Address for this network interface card. For example, the MAC Address of supposing TD-SCDMA network interface card isMAC1, the MAC Address of WLAN network interface card is MAC2, as the Microsoft Loopback Adapter address of source address isMAC99, if link management equipment is message waiting for transmission, what select is the communication that WLAN network interface card is correspondingNetwork link, now needs the Microsoft Loopback Adapter address MAC99 in message waiting for transmission to be converted toThe address MAC2 that WLAN network interface card is corresponding.
Step 204, by the message behind conversion source address, by network interface card corresponding to communication network link of selectingTransfer to the Access Network corresponding with this network interface card, then transfer to core net via Access Network, transmit by core netTo terminal links queue management equipment.
Step 205, when terminal links queue management equipment receives the message that terminal sends, according to sending reportThe mark of the terminal of carrying in literary composition finds the link queue corresponding with this terminal iidentification.
Wherein, terminal links queue management equipment can, in advance respectively for each terminal, insert this terminalAt least two network interface cards respectively corresponding communication network link are safeguarded as link queue, by the end of this terminalEnd mark is configured to the mark of this link queue, and distributes unique queue address for this link queue. Follow-upIn the time E-Packeting to data gateway, the source address in message is all used the queue address of this link queue, alsoIn other words, be sent to the message of data gateway, no matter by any bar communication network link transmission, nowAll use unique queue address. And corresponding each terminal, owing to all safeguarding unique one for each terminalTerminal links queue, and each link queue has unique queue address, therefore, is equivalent to each endBring in, being equivalent to, for this terminal provides a unique public network address information, can't affect on userThe use of network service.
Wherein, distribute unique queue address for this link queue, can be, but not limited to be set in advance oneIndividual address information, can be also that two network interface cards are distinguished one of them in corresponding network interface card information, for example, asThe MAC Address of two network interface cards of fruit is respectively MAC1 and MAC2, so, and for this link queue is distributedQueue address can be MAC1 or MAC2, can be also the MAC3 setting in advance, preferably,The embodiment of the present invention two adopts here selects network interface card information corresponding to one of them communication network link as thisThe queue address of link queue.
Particularly, under system initial state, the link queue corresponding with each terminal is non-existent, andIn the time inserting at least two network interface cards in terminal, before message transmission, terminal links queue management equipment needsSet up and safeguard a link queue for each terminal in advance, as shown in Figure 3, set up and maintenance link queueProcess can realize by following step:
Step 301, terminal links queue management equipment is distinguished at least two that receiving terminal inserts by selfThe first link management message that the communication network link that network interface card is corresponding is sent, takes in this first link management messageThe information of the terminal iidentification with this terminal and the network interface card that passes through respectively.
Wherein, in the first link management message, carry the unique identification information corresponding with this terminal, for example canBut being not limited to is the terminal identifier information arranging for each terminal in advance, or move the world of this terminalEIC equipment identification code (IMEI, InternationalMobileEquipmentIdentityNumber) information etc.
Step 302, terminal links queue management equipment obtains the terminal mark carrying in the first link management messageKnow.
Step 303, terminal links queue management equipment is using the terminal iidentification of acquisition as distributing to as this terminalThe mark of the link queue of safeguarding, and by the net carrying respectively in each the first link management message receivingDifferent link maintenances corresponding to card information are to being in the link queue of this terminal maintenance.
At a time follow-up, if communication network link corresponding to network interface card that terminal self is inserted changesTime, also comprise step 304:
Step 304, when the network interface card that terminal is inserted at self changes, for example, increases or has reduced one and insertThe network interface card entering, its corresponding communication network link also can change, and now, terminal sends the second link pipeReason message, terminal links queue management equipment is by the network interface card letter carrying in the second link management message receivingCease in the link queue that terminal iidentification that corresponding link maintenance carries to this second link management message is corresponding.
Alternatively, if in terminal, increased again one different from the communication standard of the existing network interface card having insertedNetwork interface card, for example increased a WCDMA network interface card, now, terminal can be adopted in two ways and to be sentThe second link management message:
First kind of way: only send the by communication network link corresponding to WCDMA network interface card newly increasingTwo link management messages.
The second way: the communication network link corresponding to whole network interface cards that can insert by self sends secondLink management message.
Preferably, the embodiment of the present invention two adopts first kind of way here, only by the network interface card correspondence newly increasingCommunication network link send the second link management message, like this, can save preferably network transmission resource.
Continue the process shown in above-mentioned Fig. 2, step 206, terminal links queue management equipment will receiveThe source address of message is converted to the queue address of the link queue finding. For example,, if the message receivingDuring by communication network link transmission corresponding to TD-SCDMA network interface card, the source address of the message receivingBe this TD-SCDMA NIC address, this TD-SCDMA NIC address is converted to as this terminal maintenanceThe queue address of link queue.
Step 207, by the message behind conversion source address, is transmitted to data gateway, is sent to by data gatewayEthernet.
In downlink:
Step 208, the message that terminal links queue management equipment receiving data gateway is sent. For example, canIt is the response message of terminal request being accessed to a certain webpage.
Step 209 is extracted the destination address that this message carries in the message receiving, and then will extractDestination address as the identification information of searching link queue, at the link of safeguarding respectively for different terminals in advanceIn queue, find corresponding link queue. Wherein, the destination address carrying in message can be, but not limited toBe two kinds of forms, a kind of is that this destination address is exactly the link queue mark corresponding with this link queue, anotherKind be to index according to this destination address the mark of corresponding link queue, thereby can find correspondingLink queue, for example destination address can be the queue address of this link queue. Preferably, the invention processWhat example two adopted here is first kind of way, and the destination address carrying in message is the mark of link queue,So just do not need to go again to carry out index process, can save preferably the processing resource of system.
Step 210, in each communication network link comprising in the link queue finding, according to different chainsThe loading condition that road is current, selects a communication network link according to load balancing principle.
Wherein, in many communication network links, select the wherein specific implementation of according to load balancing principleMode elaborates in above-mentioned steps 202, repeats no more here.
Step 211, terminal links queue management equipment is the destination address obtaining from the message receiving,Be converted to and select the NIC address that communication network link is corresponding. For example, suppose TD-SCDMA network interface cardMAC Address is MAC1, and the MAC Address of WLAN network interface card is MAC2, from the message receivingThe destination address obtaining is MAC3, if terminal links queue management equipment is this, message waiting for transmission is selectedBe the communication network link that WLAN network interface card is corresponding, now need the object in message waiting for transmissionAddress MAC3 is converted to the address MAC2 that WLAN network interface card is corresponding.
Step 212, the message by conversion after destination address, by the communication network link selected via coreNet and the Access Network corresponding with this communication network link, send on the corresponding network interface card of end side insertion. ?Be the message waiting for transmission that has been converted to MAC2 by destination address, by the WLAN communication of selectingNetwork service network link message transmission.
Step 213, when the network interface card inserting in terminal receives the message of network side transmitted, conversion receivesDestination address in message is Microsoft Loopback Adapter address.
Particularly, the WLAN network interface card being inserted in terminal receives by the communication network corresponding with this network interface cardWhen the message of network link transmission, obtain the destination address carrying in this message, i.e. MAC2, by this destinationLocation MAC2 is converted to Microsoft Loopback Adapter address MAC99.
Step 214, by the message after conversion destination address, is transmitted to terminal by Microsoft Loopback Adapter address.
What the use embodiment of the present invention two proposed here carries out data biography based on different links between heterogeneous networkDefeated method, to the message transmitting by heterogeneous network, can utilize the heterogeneous network resource coexisting, based onThe principle of load balancing, the communication network link that the multiple different network interface card of self reusing is corresponding, realizes heterogeneous networkSeamless switching between network link, has avoided the problem of Network Packet Loss and data delay in handoff procedure, betterGround has improved the efficiency of heterogeneous network link switching, and data transmission efficiency is improved.
