Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The embodiment of the present invention directly realizes packet domain terminal mutual visit at mobile communication packet field network to when UE dynamic IP address allocation, do not need application server or other between UE, first exchange the method that IP address communicates again.
The embodiment of the present invention can be, but not limited to for various mobile communication packet field network: Long Term Evolution (LongTermEvolution, LTE), high-speed downlink packet access (HighSpeedDownlinkPacketAccess, HSPA), enhanced high-speed downlink packets access (HSPAEvolution, HSPA+), universal mobile telecommunications system (UniversalMobileTelecommunicationsSystem, UMTS), claim code division multiple access access (CodeDivisionMultipleAccess, CDMA), TD SDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess, TD-SCDMA), general packet radio service (GeneralPacketRadioService, GPRS), enhanced data rates for gsm evolution (EnhancedDataRateforGSMEvolution, EDGE), worldwide interoperability for microwave access (WorldwideInteroperabilityforMicrowaveAccess, WiMAX).
The embodiment of the present invention is in the existing network address, and on IP address assignment mechanism, a newly-increased home address, namely identifies IP(IdentityIP) address.
This mark IP fixes each terminal and unique, and form can be IPv6 or IPv4, and completely independent with the IP address format of network allocation, identify in addition IP not participation network communication IP address assignment, do not take the IP address real resource of network service.
Fig. 1 is the flow chart of the transmission method of embodiment of the present invention packet, and as shown in the figure, the present embodiment is the concrete processing procedure of UE side, comprises the steps:
Step 101, first mobile terminal UE 1 arranges the initial data packets treating to send to the second mobile terminal UE 2, the first source address (a Src address) the first home address I-IP-1 corresponding to the first mobile terminal in initial data packets, first object address (a Dest address) the second home address I-IP-2 corresponding to UE2;
When UE1 arranges initial data packets to UE2, the live network address of UE2 is not also known in UE1 side, i.e. IP-2, and only know the home address of UE2, i.e. I-IP-2, and the home address of UE2 is unique corresponding and constant with UE, UE1 so just can be facilitated to be that UE2 sends packet, such as IP packet.
And UE1 knows network address IP-1 and the home address I-IP-1 of local terminal, so the Src address in the initial data packets arranged to UE2 extends this as I-IP-1, I-IP-2 is extended this as in one Dest address, concrete, can be filled in by the application program of UE1.
Step 102, carry out tunnel encapsulation to initial data packets obtain the first encapsulated data packet and send, the first network address ip-1 that the first packaged source address (the first encapsulation Src address) in first encapsulated data packet is UE1, first encapsulation destination address (the first encapsulation Dest address) is the second home address I-IP-2, so that the second home address is mapped as the second network address ip-2 of UE2 by gateway.
UE1 has IP tunnel function, IP initial data packets is encapsulated, first encapsulation Src address of the first encapsulated data packet after encapsulation is IP-1, first encapsulation Dest address is I-IP-2, and gateway safeguards the network address IP-1 and the home address I-IP-1 that there are UE1, also safeguard the network address IP-2 and the home address I-IP-2 that there are UE2 simultaneously; When receiving the first encapsulated data packet that UE1 sends, obtain the first encapsulation Dest address I-IP-2 of this encapsulated data packet, gateway utilizes IP mapping function that the first encapsulation Dest address I-IP-2 is mapped as the network address IP-2 of UE2.
Again as shown in Figure 1, the present embodiment also comprises the steps:
Step 103, UE2 receives the first encapsulated data packet;
Step 104, carries out tunnel decapsulation to the first encapsulated data packet, obtains first network address ip-1.
After UE2 receives the first encapsulated data packet, decapsulation is carried out to the first encapsulated data packet, after decapsulation, obtain initial IP packet, and obtain the network address IP-1 that the first encapsulation Src address is UE1.Now UE2 has obtained the network address IP-1 of UE1 by the first encapsulated data packet that this receives UE1 transmission, and itself also preserves the fixing unique identification address I-IP-1 of UE1.
Step 105, UE2 arranges the reply packet treating to send to UE1, and second source address (the 2nd Src address) of replying in packet is the second home address I-IP-2, and the second destination address (the 2nd Dest address) is the first home address I-IP-1; Replying packet can be IP packet;
Because UE2 is aware of the network address IP-1 of UE1, also know the home address I-IP-1 of UE1, so I-IP-2 is filled in the 2nd Src address that UE2 is replying packet, I-IP-1 is filled in the 2nd Dest address, concrete, can be filled in by the application program of UE1.
Step 106, carry out tunnel encapsulation to reply packet obtain the second encapsulated data packet and send, the second packaged source address (the second encapsulation Src address) in second encapsulated data packet is second network address ip-2, second encapsulation destination address (the second encapsulation Dest address) is first network address ip-1, so that the second encapsulated data packet is sent to UE1 according to first network address by gateway.
UE2 also has IP tunnel function, reply packet to IP to encapsulate, second encapsulation Src address of the second encapsulated data packet after encapsulation is IP-2, second encapsulation Dest address is IP-1, and when gateway is when receiving the second encapsulated data packet that UE1 sends, obtain the first encapsulation Dest address ip-1 of this encapsulated data packet.
Step 107, UE1 receives the second encapsulated data packet;
Step 108, carries out tunnel decapsulation to the second encapsulated data packet, obtains second network address ip 2.
After UE1 receives the second encapsulated data packet, decapsulation is carried out to the second encapsulated data packet, obtain IP after decapsulation and reply packet, and obtain the network address IP-2 that the second encapsulation Src address is UE2.Now UE1 has obtained the network address IP-2 of UE2 by the second encapsulated data packet that this receives UE2 transmission, and itself also preserves the fixing unique identification address I-IP-2 of UE2.
Like this, after this UE1 just can to send the second encapsulated data packet to UE1 as UE2 and send follow-up encapsulated data packet to UE2, because obtained the network address IP-2 of UE2, IP-2 just directly can be filled in the encapsulation Dest address of follow-up like this encapsulated data packet, and can only fill in I-IP-2 during non-sent the first encapsulated data packet.Just directly can forward according to encapsulation Dset address ip-2 after gateway receives follow-up encapsulated data packet, and not need to carry out IP mapping, the second home address is mapped as second network address.
Now UE1 and UE2 is had to network address IP and the home address I-IP of the other side, if need the process being all similar to step 105 and 106 when sending encapsulated data packet to opposite end like this, the Dest address that directly network address IP can be filled in encapsulated data packet has suffered, mapping process with regard to not needing gateway to carry out IP more like this, directly according to Dest address, encapsulated data packet being sent.
Fig. 2 is another flow chart of the transmission method of embodiment of the present invention packet, and as shown in the figure, the present embodiment is the concrete processing procedure of gateway side corresponding to a upper embodiment, comprises the steps:
Step 201, gateway receives the first encapsulated data packet that UE1 sends, the first network address ip-1, the first that the first packaged source address (the first encapsulation Src address) in first encapsulated data packet is UE1 encapsulates destination address (the first encapsulation Dest address) the second home address I-IP-2 corresponding to UE2;
Step 202, is mapped as the second network address of UE2 by the second home address;
Gateway safeguards the network address IP-1 and the home address I-IP-1 that there are UE1, also safeguards the network address IP-2 and the home address I-IP-2 that there are UE2 simultaneously; When receiving the first encapsulated data packet that UE1 sends, obtain the first encapsulation Dest address I-IP-2 of this encapsulated data packet, gateway utilizes IP mapping function that the first encapsulation Dest address I-IP-2 is mapped as the network address IP-2 of UE2.
Step 203, is sent to UE2 according to second network address ip-2 by the first encapsulated data packet, so that the first encapsulated data packet decapsulation is obtained first network address ip-1 by UE2.
Again as shown in Figure 2, the present embodiment also comprises the steps:
Step 204, gateway receives the second encapsulated data packet that UE2 sends, it is first network address ip-1 that the second network address ip-2, the second that the second packaged source address (the second encapsulation Src address) in second encapsulated data packet is UE2 encapsulates destination address (the second encapsulation Dest address);
Step 205, is sent to UE1 according to first network address by the second encapsulated data packet, so that the second encapsulated data packet decapsulation is obtained second network address ip-2 by UE1.
Because UE2 is when the first encapsulated data packet receiving UE1, just obtain the first network address ip-1 of UE1, so when encapsulation second encapsulated data packet, second encapsulation Dest address is extended this as IP-1, time such gateway receives the second encapsulated data packet, second encapsulation Dest address is IP-1, just directly according to IP-1, the second encapsulated data packet can be sent to UE1.Second encapsulated data packet decapsulation is just obtained the second network address ip-2 of UE2 by UE1.Time follow-up UE1 sends formality encapsulated data packet to UE2, IP-2 directly can be filled in the encapsulation Dest address of follow-up encapsulated data packet, and follow-up encapsulated data packet just directly can be sent to UE2 according to IP-2 by such gateway, and maps without the need to re-using IP.
The transmission method of embodiment of the present invention packet carries out the encapsulation of initial data packets in UE side, again and when not knowing the destination address of the network address, be encapsulated into the destination address of home address, IP mapping can be carried out at the gateway of network layer, home address is mapped as the network address, and do not need the network address of end side understand target terminal, the problem of UE initial ip address change can be solved, the UE of application layer only needs to know the mark IP of oneself and object UE, the change of IP address is completely transparent to it, do not need application server or miscellaneous equipment first to exchange between UE communication that IP address carries out UE again, processing method is simple.
Fig. 3 is the flow chart of the transmission method of another packet of the embodiment of the present invention, and as shown in the figure, the present embodiment is the concrete processing procedure of UE side, comprises the steps:
Step 301, UE1 arrange the initial data packets treating to send to UE2, and initial data packets comprises the first home address I-IP-1 of UE1; And the first network address ip-1 that the first source address (a Src address) in initial data packets is UE1, first object address (a Dest address) the second home address I-IP-2 corresponding to UE2; Initial data packets can be IP packet;
Send when initial data packets to UE2 at UE1, the live network address of UE2 is not also known, i.e. IP-2 in UE1 side, and only know the home address of UE2, i.e. I-IP-2, and the home address of UE2 is fixing unique and constant, and UE1 so just can be facilitated to be that UE2 sends IP packet.
And UE1 knows network address IP-1 and the home address I-IP-1 of local terminal, so a Src of UE1 extends this as the network address IP-1 of UE1 in the initial data packets sent to UE2, one Dest address extends this as the home address I-IP-2 of UE2, concrete, can be filled in by the application program of UE1.The first home address I-IP-1 of UE1 can be comprised in addition in the load of packet (Payload).
Step 302, to UE2 send initial data packets so that the second home address of initial data packets is mapped as the second network address of UE2 by gateway.
Gateway safeguards the network address IP-1 and the home address I-IP-1 that there are UE1, also safeguards the network address IP-2 and the home address I-IP-2 that there are UE2 simultaneously; When receiving the IP initial data packets that UE1 sends, obtain a Dest address I-IP-2 of this initial data packets, gateway utilizes IP mapping function that the one Dest address I-IP-2 is mapped as the network address IP-2 of UE2; Initial data packets is sent to UE2 according to the network address IP-2 of UE2 by gateway.
Again as shown in Figure 3, the present embodiment also comprises the steps:
Step 303, UE2 receive initial data packets;
Step 304, from initial data packets, obtain first network address ip-1.
After UE2 receives IP initial data packets, obtain the network address IP-2 of network address IP-1 that a Src address is a UE1 and Dest, and from the Payload of IP packet, obtain the home address I-IP-1 of UE1, learn that this packet is that UE1 sends to oneself.
Now UE2 has obtained the network address IP-1 of UE1 by the IP initial data packets that this receives UE1 transmission, and itself also preserves fixing and unique home address I-IP-1 of UE1.
Step 305, UE2 arrange the reply packet treating to send to UE1, and reply packet comprises the second home address I-IP-2 corresponding to UE2; Reply the second source address (the 2nd Src address) in packet for second network address ip-2, the second destination address (the 2nd Dest address) be first network address ip-1;
Because UE2 is aware of the network address IP-1 of UE1, so IP-2 is filled in the 2nd Src address that UE2 replys packet at IP, IP-1 is filled in 2nd Dest address, concrete, can be filled in by the application program of UE2. in the Payload of packet, comprise the home address information I-IP-2 of UE2 self in addition.
Step 306, send a reply packet to UE1, so that gateway will reply Packet Generation to UE1 according to first network address.
After gateway receives IP packet, because the 2nd Dest address is network address IP-1, so no longer need its IP mapping function process, directly IP Packet Generation will be encapsulated to UE1 according to Dest address ip-1.
Step 307, UE1 receive and reply packet, obtain second network address ip-2.
After UE1 receives IP reply packet, the 2nd Src address recognized is exactly network address IP-2,2nd Dest address is network address IP-1, can reply from IP the home address I-IP-2 obtaining UE2 the Payload of packet in addition, and itself also preserve the fixing unique identification address I-IP-2 of UE2.
Like this, after this UE1 just can to send a reply packet to UE1 as UE2 and send follow-up data bag to UE2, because obtained the network address IP-2 of UE2, IP-2 just directly can have been filled in the Dest address of such follow-up data bag, and can only fill in I-IP-2 during non-sent initial data packets.Just directly can forward according to Dset address after gateway receives follow-up data bag, and not need to carry out IP mapping, the second home address is mapped as second network address.
Now UE1 and UE2 is had to network address IP and the home address I-IP of the other side, if need the process being all similar to step 305 and 306 when sending IP packet to opposite end like this, the Dest address that directly network address IP can be filled in IP packet has suffered, so do not need gateway to carry out IP again and map process, directly according to Dest address by IP Packet Generation.
Fig. 4 is another flow chart of the transmission method of another packet of the embodiment of the present invention, and as shown in the figure, the present embodiment is the concrete processing procedure of gateway side corresponding to a upper embodiment, comprises the steps:
