Problems solved by technology

Such a long delay leads to a sharp deterioration of service QoS, seriously affecting service quality and network performance
[0014] In addition, in the wireless network, in order to ensure the quality of service, it is sometimes required that during the handover process, when the new communication parties have not completed the communication establishment, the old communication link should not be removed, because the original service node is always in reach during this process. state, so step 105 may never be completed, that is, the L3 switchover may not be completed

Embodiment Construction

[0025] In the embodiment of the present invention, in a communication system such as a mobile communication system, in order to effectively utilize wireless resources and improve network performance, the network side generally acts as a controller, and the network side controls the communication process and the behavior of most terminals in the network. Generally speaking, the network side can determine whether the terminal communicating with it needs to undergo L3 handover or whether L3 handover is taking place. With this feature, the network side can proactively notify the terminal that an L3 handover has occurred, without the terminal checking whether the new IP address is available or whether the original service node is reachable through a timeout method such as DAD. In addition, the switching of network side control can realize the transfer of context information about terminals and links between the original service node and the target service node. Using this informatio...

Abstract

The embodiment of the invention provides a processing method, a terminal and a destination service node for 3-layer switching. The method includes: sending information producing or requiring 3-layer switching towards the network side; allowing the network side informing or assisting 3-layer switching. The embodiment of the invention also provides the terminal and the destination service node, reduces time delay of the 3-layer switching and wireless wattless flow rate, accelerates the process of the terminal determining the 3-layer switching. Therefore, interrupt time delay of the services is greatly reduced, the network performance and the service quality are improved.

Description

[0001] This application is a divisional application for the application file with the application number 200610104036.X, the application date is July 31, 2006, and the title is "the processing method and system for Layer 3 switching". technical field [0002] The present invention relates to a communication method and its system, in particular to a layer-3 handover processing method and its system. Background technique [0003] In response to the rapidly increasing demand for IP addresses due to the rapid development of mobile and broadband technologies, the IETF proposed the next-generation Internet protocol-IPv6 in the 1990s. The most essential improvement of IPv6 is to increase the address length of the original IPv4 from 32 bits to 128 bits, thereby bringing almost unlimited IP address space. In addition, IPv6 also adopts many technologies such as the stateless automatic configuration of the host address. [0004] Mobile IPv6 includes three functional entities: mobile n...
