Example Embodiment

[0023] The basic idea of ​​the present invention is to improve the related process of the terminal on the basis of not affecting the current network implementation. When a random access is initiated to establish an RRC connection for the second time, the response message from the network side cannot be received, so that the RRC connection cannot be established normally. By determining whether the current cell is still a suitable cell, if not, the terminal will actively reselect to another cell. , and re-initiate the random access process after successfully camping in the new cell to achieve the purpose of improving the success rate of random access of the terminal, and at the same time ensure that the location registration and terminal services can be performed normally.

[0024] Among them, it should be noted that the "suitable cell" mentioned in the embodiment of the present invention refers to a cell that can successfully establish an RRC connection. For example, if it is de...

Abstract

The invention relates to a method, a device and a system for improving random access success rate. The method comprises the following steps of: sending radio resource control (RRC) connection requests to a network side; recording the frequency of sending the RRC connection requests; starting a first timer; judging whether a current cell is an appropriate cell according to the recorded frequency of sending the RRC connection requests if a response message returned by the network side is not received after the first timer is overtime; and choosing to dwell in a new cell and initiating a new random access process if the current cell is not the appropriate cell. By adopting the method, the device and the system provided by the embodiment of the invention, the problems that position registration and a terminal service cannot be performed normally because random access fails due to incapability of normally establishing RRC connection by initiating random access for many times when a terminal dwells in a certain cell can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for improving the success rate of random access. Background technique [0002] In the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system of the third generation mobile communication system, when the terminal resides in a suitable (suitable) cell for location registration or when the user is in the cell When initiating a service, it first needs to access the network. At this time, the NAS (Non-Access-Stratum, non-access stratum) entity will notify the RRC (Radio Resource Control, radio resource control) layer entity to establish an RRC connection with the network side; when the RRC layer entity When sending the uplink UU port signaling RRC Connection Request (RRC Connection Request) to the network side, if the current cell has poor signal quality, strong interference, etc., the terminal will not be able to receive t...
