Embodiment 1

[0077] In this embodiment, when the UE fails to access the random access, for example, the UE has not yet connected to the system after sending the sync_UL code for the maximum number of times, the UE records the process of random access failure, for example: at which step it fails, at each step The sync_UL code or PRACH and E-RUCCH are sent several times.

[0078] Specifically, the UE can record the failure event, including the following information when the event occurs, and of course one or several parameters can be selected for recording (the parameters are not in order):

[0079] 1. PRACH access process information:

[0080] At which step it failed and / or how many times sync_UL code or PRACH and E-RUCCH were sent at each step.

[0081] 2. Wireless environment measurement information:

[0082] During implementation, it may be the radio signal or / and channel quality information measured by the UE, such as pilot signal quality, reference symbol signal quality, and the like...

Embodiment 2

[0092] In this embodiment, the random access is successful only after the UE sends the Sync_UL code multiple times, and there is no corresponding PRACH or E-RUCCH failure. Finally, the UE successfully accesses the system. At this time, the UE can report the number of times it sends the Sync_UL code. And the adopted Sync_UL code, etc. At this time, the network side can also count the number of transmission times of which Sync_UL code group is the most, whether it is a common random access code group or an HSUPA random access code group. If the HSUPA random access code group sends more times, it can be judged that there may be a large number of code words in the code group. A large number of UEs perform HSUPA random access, causing conflicts in the transmission of Sync_UL codes, resulting in multiple Sync_UL codes. For transmission, more Sync_UL codes can be assigned to the random access code group of HSUPA.

[0093] The UE can record this event, including the following informa...

Embodiment 3

[0101] In this embodiment, when the UE succeeds in sending uplink information on the PRACH and E-RUCCH multiple times, the UE can record the success of sending the PRACH and E-RUCCH several times, or record whether it has passed multiple PRACH and E-RUCCH -RUCCH is sent successfully, and at the same time, it is recorded how many times the Sync_UL code is sent before and after the failure of sending PRACH and E-RUCCH.

[0102] At this time, the network side can count the number of times the UE sends uplink information on the PRACH and E-RUCCH, and use it to determine whether the parameter setting of the PRACH is unreasonable. For example, a large number of statistics show that the E-RUCCH always needs to be sent multiple times to be successful, so it is possible that the E-RUCCH channel configuration is relatively small. It may be necessary to increase the number of channels of the E-RUCCH.

[0103] At the same time, the number of transmissions of the sync_UL code can also be ...

Abstract

The invention discloses methods and equipment for reporting information generated in a random access process and determining parameters. The method for reporting the information generated in the random access process comprises the following steps: user equipment acquires information generated in the random access process; and the user equipment reports the acquired information to a network side. By adopting the methods and the equipment, access conditions such as access failures of corresponding user equipment and the like can be acquired by the network side under the conditions that the random access fails in the random access process and the like.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and equipment for reporting information generated in a random access process and determining parameters. Background technique [0002] figure 1 It is a schematic diagram of the random access process in the prior art, as shown in the figure, the random access process is as follows: [0003] Step 101, for a UE (User Equipment, user equipment) that does not support HSUPA (High Speed ​​Uplink Packet Access) capability, randomly select a sync_UL code from 8 sync_UL (uplink synchronization) codes in a cell , performing random access on an Up_PCH (Up_PilotChannel, uplink pilot channel) channel. If it is a UE that supports HSUPA, the UE will select the sync_UL code group according to whether to access HSUPA, because the network that supports HSUPA will group the sync_UL codes, a group of codes identifies random access of HSUPA, a group of codes Used to identify commo...
