Description
Technical field
The present invention relates to moving communicating field, espespecially a kind of method, access service router (ASR) and system realizing dynamically increasing terminal available port.
Background technology
As everyone knows, in internet, applications, terminal needs effective network (IP) address just can carry out access to netwoks.An effective IP address represents the identity of user and residing network topological location.Effective IP address often GC group connector only to use on corresponding network topological location.No doubt no problem for fixed terminal, but, for mobile terminal, when equipment shifts out network topological location, can lose efficacy in IP address, although can by regaining IP to continue access to netwoks, some need the access to netwoks carried out continuously to be interrupted, such as IP phone, have impact on terminal communication like this.
In order to solve the mobile management problem of terminal, Mobile IP, proxy-mobile IP, universal tunnel tunneling etc. have made corresponding design.The mobile management to mobile node is realized by introducing fixed anchor point.Although adopt the method for fixed anchor point can solve IP Problem of Failure, even if but existence communication terminal and opposite end are apart from very near, when terminal and anchor point distant, the transceiving data message between terminal and opposite end still needs around to fixed anchor point, could realize the communication with Correspondent Node.Therefore, there is route detour problem.
In order to solve route detour problem, the mobile management of terminal have employed the technology be separated with position based on user identity.Fig. 1 is the existing network architecture schematic diagram be separated with position based on user identity, as shown in Figure 1, is divided into by network and does not have overlapping Access Network and backbone network in topology; Access Network is positioned at the edge of backbone network, is responsible for the access of all terminals; Backbone network is responsible for route and the forwarding of the inter-terminal data message accessed.The identify label of terminal use uses access mark (AID) of not moving because of on-position and the position of network and changing to represent.The station location marker used at backbone network is represented by the Route Distinguisher (RID) of network allocation.Visible, the method still needs a part of IP address assignment to use as identify label to terminal use.And in the IPv4 environment of Address Run Short, adopt the method to exacerbate the problem of Address Run Short.Based on this, the method for superposition port numbers in access service router (ASR) distributing IP address as AID is suggested.If using 1000 port numbers under ASR IP address and this IP address as the new AID of user.Each IP address comprises 65536 ports, then the codomain of original AID can at least expand 40 times (some ports are the port of stationary applications, as 80 ports, are not easy to be used as identifying user).After terminal is linked into access service router (ASR), first, the private network IP address (such as, 10.1.1.1) ASR territory is obtained from ASR.ASR obtains the AID of this terminal from the identity server of disposing in a network by suitable authorizing procedure, the AID now obtained is the form (example that IP address adds port numbers, 202.1.2.3@(2000-2999), home address 202.1.2.3 are the AID of this terminal from port 2000-2999).When peer node in terminal access network, terminal uses its private network IP address as source address, and random port, as destination address (such as, 10.1.1.1@34567), sends out packet to opposite end.After message is sent to ASR, (usually uses NAT method) within the 2000-2999 port that ASR is mapped to 202.1.2.3, as 202.1.2.3@2100, message is sent.By this method, terminal is made the AID of oneself in fact can be used as the source address of communication and then communicate with peer node.
Adopt the method for this distribution AID, when the port numbers distributing to terminal is fewer, the valued space of AID is larger.But when terminal carries out application access, adopt the method for AID to there is the not enough problem of application available port possibility, the port numbers GC group connector distributing to terminal carries out the operable port number of application access.The application of terminal, all based on transmission control protocol/User Datagram Protoco (UDP) (TCP/UPD) agreement, all needs the available port on occupied terminal, and when in terminal, available port is fully occupied, terminal cannot initiate new business.And apply P2P application more widely at present, often take thousands of ports, for when only distributing to the terminal of less port numbers as its AID, this type of business is often difficult to carry out, and the phenomenon of available port deficiency is more obvious.The application that cannot obtain available port GC group connector can not accesses network, and this has had a strong impact on the Consumer's Experience of mobile terminal, is also unfavorable for carrying out of Operator Specific Service.
In sum, the method for AID is adopted can to realize the mobile management of terminal.But there is the problem of terminal available port deficiency, along with the ports such as P2P take the increase of larger application, the situation of available port deficiency is more serious.Have impact on user to the use of application and the carrying out of Operator Specific Service.
