Problems solved by technology

[0003] However, with the aforementioned method, if the registration message sent by the mobile device is too frequent, the system may cause Service Disruption; and the registration message itself is a flood message on the third layer , Therefore, in the case of network congestion or rapid movement, the information may be inverted (disorder), which will cause handover (Handover) is not smooth or the risk of data delay / drop; In some cases, it will affect the quality of the service (such as Ping-Pong registration), and even cause the service to be interrupted. In addition, legal / illegal users may also have malicious attacks, such as continuously sending registration messages to paralyze the system

Embodiment Construction

[0024] For a preferred embodiment of the method for improving smooth handover in mobile communication of the present invention, please refer to image 3 As shown in the processing flow of the mobile device, first, when the mobile device detects the registration request message sent by the proxy server at the time point Tr0 (step S31), it will record this time point Tr0 in the base station controller Compared with the time point Trn (step S32) of the last request registration of (BSC), the distance between the two time points is generally a preset value Trv (step S33), indicating that the time required for this registration is too long with the time of last registration. Close, so ignore this new registration request and do not perform the registration procedure (step S34), the aforementioned preset value Trm can be the average registration time; otherwise, if the distance between the two time points is greater than the preset value Trv, then carry out general Registration prog...

Abstract

A method to improve connection smooth-going of operative communication works in equipment of operative end as the new register request will be ignored or other wise to carry on normal registering program if the point distance of time for last time of registering request is less than a preset figure at the point of this time when message of registering request emitted by agent servor is detected at a point of time; in the agent servor as the cold registering request will be deleted and only new registering request will be processed if the state of former registering request is in confirmation, channel production or agent ARP, or the cold registering request will be processed continuously and normally if the state of former registering request is in roll back of exiting when a new registering request is received.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for improving smooth handover in mobile communication. Background technique [0002] In the implementation of the current mobile IP (Mobile IP) communication protocol, such as figure 1 As shown, when a mobile device 11 (such as a mobile phone, a notebook computer) moves from a local network (Home network) to a foreign network (Foreign network), a registration (Registration) message needs to be sent to inform the system of its location Where, its message flow is as follows figure 2 As shown, the foreign agent server 12 (Foreignagent) continues to broadcast to notify mobile devices entering its range to register, and when receiving a registration message with a new IP address sent by a mobile device, it will This message is forwarded to the local proxy server 13 (Home agent), and when the foreign proxy server 12 receives the reply from the local proxy serve...
