Method for realizing communication between host devices and network side device

Abstract

The invention provides a method for realizing communication between host devices and a network side device. The method comprises the following steps: the network side device receives a request of communicating with a second host device sent by a first host device, wherein, position identification and identity identification of the first host device are separated, and the second host device takes position identification as identity identification; the network side device distributes a temporary identification ID and a temporary forwarding port for a session between the second host device and the first host device, and forwards a communication data packet between the first host device and the second host device through the temporary identification ID and the temporary forwarding port. By applying the method and the network side device in the invention, that a host device with separated position identification and identity identification visits a traditional host device can be realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for realizing communication between host devices and a network side device. Background technique [0002] In a traditional mobile communication system using IP addresses, the IP address is used not only as a user's location identifier but also as a user's identity identifier. With the development of network technology, the number of users participating in Internet information interaction is increasing, and the demand for mobility is becoming more and more obvious. The IP address is used as both the user's location identifier and the user's identity identifier. Problems in routing scalability, mobility, and security are also gradually exposed. [0003] First of all, under the background of the rapid growth of mobile users and the gradual deployment of IPv6, the "super-linear" growth rate of the routing table may bring serious consequences, and the problem o...

Problems solved by technology

However, the transmission connection of the TCP / IP protocol is based on the IP address. When the IP address of the mobile node changes, its original communication service is still bound to the old IP address, which will cause the interruption of the communication service and make it difficult to meet User needs for real-time services

Finally, the semantic overload of IP addresses also leads to some security problems: there is no precise correspondence between IP addresses and users, and it cannot accurately reflect the real identity of users, which increases the complexity and difficulty of access control, and to a certain extent affect the effectiveness of various security mechanisms

[0009] It can be seen that the HIP-Proxy solution in the prior art cannot realize the communication with the traditional host initiated by the host separated from the identity identifier and the location identifier, and, in the HIP-Proxy solution, due to the non-HIP host and the HIP-Proxy The mapping relationship between them is static, therefore, each non-HIP host can only communicate with the HIP host through a fixed HIP-Proxy, which is less flexible
