Implementation method, system and device for allocating target forward address of user device

Abstract

The invention discloses a realizing method, a system and a device for user equipment (UE) distributing target-conversion access (T-CoA). A target-access router (T-AR) which is used as a proxy server requests a dynamic host computer protocol server (DHCP Server) to distribute T-CoA for the switched UE; and the DHCP Server distributes T-CoA for the UE. The inventive method ensures that the T-AR can be used as a proxy server to request the DHCP Server to distribute T-CoA for the switched UE, and the DHCP Server distributes T-CoA for the UE to support continuous communication. Obviously, this ensures that the UE can be performed to normal communication after being switched to a T-AR, therefore user satisfaction can be greatly improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, system and device for allocating a target care-of address (T-CoA) for a user equipment (UE). Background technique [0002] With the development of communication technology, the sixth version of Mobile Internet Protocol (MIPv6) technology is gradually getting people's attention. [0003] Currently, when a UE such as a mobile station (MS) supporting MIPv6 communicates with an external network through a home agent (HA) or an access router (AR), local network entities such as the home agent (HA) will assign a home address (HoA) to the UE. , AR and other communication entities will assign a care-of address (CoA) to the UE, and the HA will save the binding information between the HoA and CoA; in this way, the UE can carry the assigned HoA and CoA in the communication information sent during communication. , and the HA forwards the communication information correctly accordi...

Problems solved by technology

[0030] However, in the current practical application, there is no protocol content or specific operation to explain how to assign a new available T-CoA to the UE

It can be seen that when the UE is handed over from S-AR to T-AR, even if it is determined that the T-CoA corresponding to the T-AR configured by the UE itself is unavailable, it cannot effectively provide any method to allocate a new available T-CoA for the UE; this will As a result, UE cannot communicate normally after switching to T-AR, which seriously reduces user satisfaction
