Description
Technical field
The present invention relates to moving communicating field and internet arena more particularly to a kind of address resolution method, device and letters
Cease transmission method.
Background technology
Mobile Internet is the developing direction of Future Internet, but mobile management is the disaster that mobile Internet faces
Topic.It is well known that terminal will access IP internets, it just must be from one effective IP address of network application.The IP address has
Double attribute had not only represented the identity of user but also had represented the network topological location residing for user.When user certain topology location (such as
Under certain access gateway) acquired an IP address after, the IP address can only the topology location use (e.g., can only be one
It is used in the compass of competency of a couple in router).For fixed terminal, no doubt there is no problem for this, but for mobile terminal, when
Terminal is after range that a couple in router is administered is moved to the range of another couple in router administration, above-mentioned IP
Location can become an invalid address.At this point, terminal must obtain a new IP address from new topology location again.In this way
It can not just ensure the continuity of IP-based upper-layer service, for example, terminal user is playing IP phone, then the call can be broken.
In order to solve this problem, industry begin one's study identity-based position separation technology, the technology attempt solve terminal
Must redistribute IP address after couple in router the problem of, basic principle is to assign an identity for terminal, together
When again assign a station location marker.
As shown in Figure 1, it is the framework of a kind of identity information and location information separated network, the system is by access server
(Access Service Router, ASR), user equipment (User Equipment, UE), identity position register
(Identification ＆ Location Register, ILR) and authentication center (Authentication Center, AC)
Deng composition, wherein, access server ASR identifies to access user equipment for user equipment dispensing position；ILR is protecting
The current location information of user is deposited, and the function that current location information is inquired according to the identity information of user is outwardly provided；AC
Then undertake access authentication of user work(；DHCP undertakes the distribution of unique identity symbol (Access Identification, AID)
Function, and the AID distributed must belong to same subnet.
User equipment (or host) is gathered around there are one unique identity (AID), no matter how to be moved in a network, even
Which it is connected under ASR, the AID of user equipment remains constant；After user equipment is linked into network, it can also be assigned one
Station location marker (RID), it is generally current by user equipment to represent topology location (characterization routing iinformation) that terminal is presently in
The ASR distribution of connection.
In the network of identity position separation, when two users' terminal needs communication, both sides are using respective AID as communication
Source/destination address, by taking Fig. 1 as an example, it is assumed that UE1 is source (transmitting terminal), holds (receiving terminal) for the purpose of UE2, UE1 and UE2 into
The step of row communication, includes：
(1), IP packet is sent to the ASR1 of source connection by source；
(2), ASR1 inquires to obtain the current RID of destination, and the data packet that source is sent according to the AID of destination
Tunnel encapsulation (e.g., IP in IP tunnels) is carried out, and packaged message is sent to the ASR2 of destination connection, wherein, tunnel
The source/destination address in road is respectively the RID of source and the RID of destination；
(3) ASR2 disassembles tunnel, takes out the message sent out by source wherein carried, and be sent to destination.
ARP (address resolution protocol) is that network layer carries out address of cache and the technology namely IP of conversion to data link layer
Address to MAC address of cache and conversion, ARP data packets can only be propagated in a broadcast domain, and router does not forward ARP messages.
As shown in Figure 1, the AID2 of the AID1 and UE2 of UE1 belongs to same subnet, but UE1 and UE2 is not in same broadcast domain
In, therefore when UE1 and UE2 are into row data communication, UE1 can not find UE2.
The process of UE1 and UE2 into row data communication is as follows：
UE1 check UE2 and oneself whether in same subnet, if it is, UE1 directly transmits ARP broadcast requests,
The MAC Address of UE2 is inquired, since router does not forward ARP broadcast requests, and UE2 and UE1 is not in same broadcast domain
In, therefore UE1 can not find UE2, communication failure.
