Method, Apparatus, and System for Accessing LTE Network by Mobile Terminal

A method comprising:

• determining, by a mobile terminal, that a quantity of attach failures or tracking area update (TAU) failures of the mobile terminal in accessing a long term evolution (LTE) network reaches a threshold;
• starting, by the mobile terminal, a T3402 timer and disabling, by the mobile terminal, an evolved universal terrestrial radio access (E-UTRA) capability in response to the quantity of attach failures or TAU failures of the mobile terminal reaching the threshold, wherein duration of the T3402 timer is based on a moving speed of the mobile terminal, and when the moving speed reaches a first value, the duration of the T3402 timer is less than first default duration;
• and
• after the T3402 timer expires, searching for, by the mobile terminal, the LTE network again, and sending, by the mobile terminal, an attach request to a first network device of the LTE network.

A mobile terminal, wherein the mobile terminal comprises a non-transitory memory and one or more processors;

• the memory is coupled to the one or more processors;
• the memory is configured to store computer program code;
• the computer program code comprises computer instructions;
• and the one or more processors are configured to invoke the computer instructions to cause the mobile terminal to perform:
• determining that a quantity of attach failures or tracking area update (TAU) failures of the mobile terminal reaches a threshold in accessing a long term evolution (LTE) network;
• starting a T3402 timer and disabling an E-UTRA capability in response to the quantity of attach failures or TAU failures of the mobile terminal reaching the threshold, wherein duration of the T3402 timer is based on a moving speed of the mobile terminal, and when the moving speed reaches a first value, the duration of the T3402 timer is less than first default duration;
• and
• after the T3402 timer expires, searching for the LTE network again, and sending an attach request to a first network device of the LTE network.
