Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] figure 2 It is a flow chart of the method for locating the cause of UE random access failure provided by the present invention.

[0045] like figure 2 As shown, the method includes:

[0046] In step 201, the UE reports to the network side the random access parameters adopted by the UE during the failed random access process.

[0047] Step 202, the network side locates the cause of the random access failure of the UE according to the random access parameters reported by the UE.

[0048] see figure 1 As shown in the UE random access flow chart, it can be known that the UE fails in random access during the random access process, including: in step 104, the UE does not receive the FPACH sent by the network side and the retransmission counter value of the UE is already 0; In step 108, the UE does not receive the FACH message sent by the network side.

Abstract

The invention provides a method and a system for locating a random access failure reason of User Equipment (UE). The method comprises the following steps that: the UE reports a random access parameter employed by the UE in a failed random access process to the network side; and the network side locates the reason of the random access failure of the UE according to the random access parameter reported by the UE. The system comprises the User Equipment (UE) and a network side apparatus, wherein the UE is used for reporting a random access parameter employed by the UE in a failed random access process to the network side apparatus; and the network side apparatus is used for locating the reason of the random access failure of the UE according to the random access parameter reported by the UE. By employing the method and the system provided by the invention, the reason of the random access failure of the UE can be located conveniently, so that the network performance can be effectively and quickly optimized by the network side.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and system for locating the cause of random access failure of user equipment. Background technique [0002] In the TD-SCDMA system, if the user equipment (UE) wants to access the network, the UE must first establish downlink synchronization with the network. After the UE establishes downlink synchronization with the network, since the UE cannot determine the distance between the UE and the network, The UE needs to obtain proper uplink transmission time and power through the uplink random access procedure. [0003] figure 1 is a UE random access flow chart in the prior art. [0004] like figure 1 As shown, the process includes: [0005] Step 101, the UE sets the initial value M of the maximum retransmission counter of the uplink synchronization (SYNC_UL) signature sequence. [0006] The initial value M in this step is configured by the network s...
