Description
Technical field
The present invention relates to communication technical field, relate in particular to method for communicating and network equipment between a kind of realization main process equipment.
Background technology
In the traditional GSM that uses the IP address, the IP address is not only as user's station location marker but also as user's identify label.Along with development of internet technology; It is more and more to participate in the mutual number of users of internet information; Being used for for ambulant demand also more and more obviously, not only also came out as user's station location marker but also as the problem of user's aspects such as route autgmentability, mobility and fail safe that identify label caused gradually in the IP address.
At first, under the overall background that mobile subscriber number rapidly increases and IPv6 progressively disposes, the growth rate of routing table " superlinearity " may be brought serious consequence, and the route scalability problem is needed solution badly.Moreover the user has determined its IP address to change to ambulant requirement, with the variation of the Network Access Point of representing this user.And the transmission of ICP/IP protocol connection is based on the IP address, and when the IP address of mobile node changed, its original communication service still was bundled on the old IP address, and this will cause communication service interruption, be difficult to satisfy the needs of user to real-time service.At last; The semantic overload in IP address has also caused some safety problems: do not have accurate corresponding relation between IP address and the user; The true identity that can not accurately reflect the user; This has strengthened the complexity and the difficulty of access control, and has influenced the usefulness of various Security Assurance Mechanisms to a certain extent.
To the problems referred to above; Proposed the thought that location tags separates in the prior art, be about to IP address of host identify label function and station location marker functional separation, for each main frame is provided with identify label and station location marker respectively; Identify label wherein only is used to identify the identity of main frame; The IP address only is used to identify the current present position of main frame, thereby realizes that at the main frame place location identifier and the thorough of identification identifier separate, and then has solved the problems referred to above.
Yet; In the canonical system of position-based label separating thought; Usually exist the main frame of station location marker, promptly adopt the legacy hosts of unified sign (for example IP address), and the main frame that the guarantee station location marker separates with identify label is to the visit of traditional services as identify label and station location marker as identify label; Ensureing that promptly main frame that station location marker separates with identify label can initiate and the communicating by letter of legacy hosts, is one of current problem demanding prompt solution.
At present, how the main frame that separates with identify label about station location marker initiates and the communicating by letter of legacy hosts, and does not also have the corresponding techniques scheme.The scheme that the main frame that only exists legacy hosts initiation and station location marker to separate with identify label in the prior art communicates, the HIP that promptly in the HIP agreement, proposes acts on behalf of (HIP-Proxy) solution, introduces in detail below:
In system based on the HIP agreement, station location marker is called the non-HIP main frame as the legacy hosts of identify label, the main frame that identify label separates with station location marker is called the HIP main frame.In order to realize that the non-HIP main frame can visit the HIP main frame, the output of non-HIP main frame (outgoing traffic) routed path is provided with HIP-Proxy, and this HIP-Proxy represents all HIP signalings of non-HIP host process as intermediate node.
Wherein, Mapping relations between non-HIP main frame and the HIP-Proxy are static; Be that each non-HIP main frame is through predetermined HIP-Proxy visit HIP main frame, the predetermined all HIP signalings of one or more non-HIP host process of each HIP-Proxy representative.
It is thus clear that; The main frame that HIP-Proxy solution of the prior art can't realize being separated with station location marker by identify label is initiated and the communicating by letter of legacy hosts, and, in the HIP-Proxy solution; Because the mapping relations between non-HIP main frame and the HIP-Proxy are static; Therefore, each non-HIP main frame can only communicate through fixing HIP-Proxy and HIP main frame, and flexibility is relatively poor.
Summary of the invention
In view of this, the invention provides method for communicating and network equipment between a kind of realization main process equipment, so that the main frame that the realization station location marker separates with identify label is to the visit of legacy hosts.
The technical scheme that the present invention adopts specifically is achieved in that
Method for communicating between a kind of realization main process equipment, this method comprises:
Network equipment receives the request of communicating by letter with second main process equipment that first main process equipment sends, and wherein, the station location marker of first main process equipment separates with identify label, second main process equipment with station location marker as identify label;
Network equipment is that the session between this second main process equipment and first main process equipment distributes temporary mark ID and the interim port of transmitting, through said temporary mark ID with transmit port and between first main process equipment and second main process equipment, transmit communication data packet temporarily.
A kind of network equipment of communicating by letter between main process equipment realized, this network equipment comprises:
Receiving element is used to receive the request of communicating by letter with second main process equipment that first main process equipment sends, and wherein, the station location marker of first main process equipment separates with identify label, second main process equipment with station location marker as identify label;
