Method for indicating switch-over successful or not in switching course

A handover process, a successful technology, applied in the direction of communication, electrical components, radio/inductive link selection arrangement between multiple stations, etc., can solve problems such as bad business impact, bad user experience, long-term interruption of business connections, etc.

Problems solved by technology

[0005] It can be seen that in the above-mentioned handover process, the AT cannot know whether the handover is successful in time. For the case of handover failure, the AT must not receive the resource assignment from the AN after the timer expires, or when it receives a return from the AN. Only when the Connection Open Response message is received, can we know that the handover failed, and then re-establish the connection with the source cell or switch to another cell, which will inevitably cause a large delay, resulting in a long-term interruption of the service connection, which will affect the ongoing AT The business has a bad impact and brings bad feelings to users

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] Referring to Fig. 2, the basic idea of ​​the present invention is: in the handover process of AT, after AN receives the Access Probe message that AT sends, returns Access Grant message to AT, and carries the information of switching success in AccessGrant message .

[0030] Wherein, a field may be added in the Access Grant message to indicate whether the handover is successful.

[0031] AT not only initiates pointers when switching, but also initiates probes for ordinary random access ATs. The contents of the probes are modulated with mutually orthogonal code groups. Orthogonal code resources used by ordinary random access probes are the same as The orthogonal code resources used by the handover access probe are different. When the AN receives t...

Abstract

This invention discloses a method for indicating if a switch is successful during switch including: after AN receives a message of an access probe sent by AT, it feeds back the access grant information to the AT and carries the information if the switch is successful in the access grant message and AT can get to know if a switch is successful timely.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for indicating whether the handover is successful during the handover process. Background technique [0002] Air interface evolution (Air interface evolution, AIE) is a wireless access technology proposed by the 3rd Generation Partnership Project 2 (3GPP2). Carrier Enhanced-High-speed Data (Evolution-Data Only, EV-DO) technology, the goal is to increase the peak rate and maintain backward compatibility; the second stage introduces more advanced technologies, such as Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) technology, etc., can greatly improve the spectrum efficiency and peak rate of the wireless access system, and is a long-term evolution plan of the 3GPP2 standard. In the Loosely Backward Compatible (LBC) mode of the AIE second-stage technology, the forward and reverse data multiplexing adopts the access scheme (...
