Problems solved by technology

[0005] If the terminal cannot be effectively controlled to perform the initial access operation as quickly as possible, the network may reserve resources for a long time, resulting in serious waste of resources, which in turn will reduce cell throughput and affect system performance, especially for those requiring LTE system characterized by high data rate, low response time and optimal packet access

Embodiment Construction

[0031] The core of the present invention is aimed at the requirements of the LTE system for reduced response time, higher user data rate and system capacity. During the connection re-establishment process after the wireless link is lost, a reasonable Connection re-establishment delay time, the control terminal completes the connection re-establishment process within a certain delay time.

[0032] The connection reestablishment delay time is determined by part or all of the time required to search for cells, the time required to search for sectors, the time required to obtain system information, and the delay caused by initial access operations. Specifically, if the target cell to be searched in the neighbor cell list maintained by the terminal is located on the same frequency layer, the connection reestablishment delay time is determined by the time required to search for the cell, the time required to read system information, and the delay caused by the initial access process....

Abstract

This invention discloses a method for controlling re-setting up connections in a long-term evolution system including: a terminal tests failure of a radio link and begins initial access operation on an initial access channel in the delay time of re-set up. This invention also discloses a terminal including a unit for setting delay time of re-setting up connection used in determining delay time according to the kind of target local area searched, a test unit connected with the set unit and used in testing if the executing time of the re-set up of the terminal exceeds the confirmed time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and a terminal for controlling connection reestablishment in a long term evolution system. Background technique [0002] In order to make the wireless access technology of 3GPP (The 3rd Generation Partnership Project, third-generation mobile communication standardization partner project) in a favorable position in the environment of fierce competition in future mobile communication technology, it is necessary to consider the long-term evolution of the 3GPP wireless access technology ( LTE, Long Term Evolution). The goal of Long-Term Evolution is to develop a framework for radio access technologies characterized by high data rates, low response times, and optimal packet access. Therefore, important aspects of LTE include reduced response time, higher user data rates, improved system capacity and coverage, and reduced operator expense. [0003] Due to the ...
