Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of realize communicating between main process equipment method and network equipment.
Background technology
In the conventional mobile communications system using IP address, IP the address not only station location marker as user but also the identify label as user.Along with the development of network technology, participate in the mutual number of users of internet information to get more and more, for also more and more obvious for ambulant demand, the IP address problem of the aspect such as Routing expansion, mobility and fail safe that not only station location marker as user but also the identify label as user had caused also comes out gradually.
First, under the overall background that mobile subscriber number rapidly increases and IPv6 progressively disposes, the growth rate of routing table " superlinearity " may bring serious consequence, and route scalability problem needs solution badly.Moreover user determines its IP address to ambulant requirement and must change, to represent the change of the Network Access Point of this user.And the transmission connection of ICP/IP protocol is IP address-based, when the IP address of mobile node changes, its original communication service is still bundled on old IP address, and this will cause communication service interruption, is difficult to meet the needs of user to real time service.Finally, IP address semanteme overload also results in some safety problems: do not have accurate corresponding relation between IP address and user, accurately can not reflect the true identity of user, which increase the complexity and difficulties of access control, and have impact on the usefulness of various Security Assurance Mechanism to a certain extent.
For the problems referred to above, the thought that location tags is separated is proposed in prior art, host identities identification function by IP address separates with station location marker function, for each main frame arranges identify label and station location marker respectively, identify label is wherein only for identifying the identity of main frame, IP address only for identifying the current present position of main frame, thus realizes location identifier at main frame place and is separated with the thorough of identification identifier, and then solves the problems referred to above.
But, in the canonical system of position-based label separating thought, usually exist the main frame of station location marker as identify label, namely adopt unifying identifier (such as IP address) as the legacy hosts of identify label and station location marker, and ensure that main frame that station location marker is separated with identify label is to the access of traditional services, namely ensureing that the main frame that station location marker is separated with identify label can initiate the communication with legacy hosts, is one of current problem demanding prompt solution.
At present, how the main frame be separated with identify label about station location marker initiates the communication with legacy hosts, does not also have corresponding technical scheme.Only there is the scheme that legacy hosts initiates to carry out with the main frame that station location marker is separated with identify label communicating in prior art, the HIP namely proposed in HIP agreement acts on behalf of (HIP-Proxy) solution, introduces in detail below:
In the system based on HIP agreement, station location marker is called non-HIP main frame as the legacy hosts of identify label, and the main frame that identify label is separated with station location marker is called HIP main frame.HIP main frame can be accessed to realize non-HIP main frame, output (outgoing traffic) routed path of non-HIP main frame is provided with HIP-Proxy, this HIP-Proxy, as intermediate node, represents the HIP signaling that non-HIP host process is all.
Wherein, mapping relations between non-HIP main frame and HIP-Proxy are static, namely each non-HIP main frame accesses HIP main frame by predetermined HIP-Proxy, and each HIP-Proxy represents all HIP signalings of predetermined one or more non-HIP host process.
Visible, the communication with legacy hosts initiated by the main frame that HIP-Proxy solution of the prior art cannot realize being separated with station location marker by identify label, and, in HIP-Proxy solution, because the mapping relations between non-HIP main frame and HIP-Proxy are static, therefore, each non-HIP main frame can only be communicated by fixing HIP-Proxy and HIP main frame, and flexibility is poor.
