Problems solved by technology

However, when the mobile terminal needs to re-register to the PLMN in Shenzhen, the interference will be particularly large if there are BAND3 co-frequency base station cells of China Unicom and China Telecom around the gateway.
At this time, the mobile terminal needs to establish a connection with the network to do Internet access services, etc., and switch from the idle state to the connected state. At this time, the mobile terminal needs to initiate a random access process. Failed, this puts the mobile terminal in a very embarrassing situation, and it shows that there is a service, but it cannot do business

[0035] figure 2 It is a flow chart of the processing method after multiple random access failures provided by the first embodiment of the present invention. This embodiment is a processing method after multiple random access failures performed by the processing device after multiple random access failures. Specifically, the processing method after multiple random access failures provided in this embodiment can be applied to a mobile terminal, so as to control the mobile terminal to perform a random access process. Such as figure 2 As shown, the processing method after multiple random access failures in this embodiment may include the following steps:

[0036] Step S11, establishing a connection request.

[0037] Specifically, the NAS layer of the mobile terminal triggers a service request signal (SERVICEREQUEST) through the underlying access layer, and when the mobility management layer (MM layer) receives the service request signal, it triggers sending a connection estab...

Abstract

The invention provides a processing method after multiple failures in random access. The method comprises that a connection request is established, and a random access process is initiated according to the connection request; if the random access process fails, one is added to the failure times; and when the failure times reach preset failure times and a signal to noise ratio (SNR) is beyond a preset SNR range, a base station cell corresponding to a present position is added to a base station cell forbidden list, and reselection of another base station cell is initiated to search a proper basestation cell for residence again. The invention also provides a processing device after multiple failures in random access. The processing method and device can avoid a mobile terminal, implementingservices, from residing certain base station cell for random access when random access fails due to interference, the mobile terminal can be rapidly switched to the other base station cell for the random access process, and thus, the mobile terminal can obtain normal services rapidly.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a processing method and device for multiple random access failures. Background technique [0002] At present, in the actual wireless network environment, the signal coverage of a cell at the boundary of a certain operator's base station cell coverage is already very weak, and at this time another operator's cell has a strong signal and is a cell of the same frequency signal, there will be strong co-channel interference, so random access process failures often occur on the boundary of the cell coverage of the base station. The random access process is the first process for the mobile terminal to access the cell of the base station to obtain resources allocated by the network. [0003] However, in the prior art, after multiple times of random access failures, the cell of the base station that can be found will be continuously accessed. For example, from Hong ...
