Cell access method, apparatus, and system

A user equipment comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory to execute the instructions to:
• receive a first signal offset of a first cell and a random access failure threshold of the first cell when the user equipment camps on the first cell;
• attempt to perform random access to the first cell, and count a quantity of random access failures;
• perform cell reselection by using the first signal offset for the first cell if the quantity of random access failures reaches the random access failure threshold;
• and
• perform cell reselection by using the first signal offset for the first cell when camping on a second cell if the second cell is selected to camp on in the cell reselection when camping on the first cell.

A communication system comprising:

• a base station, configured to send a first signal offset of a first cell and a random access failure threshold of the first cell to a user equipment;
• the user equipment is configured to:
• receive the first signal offset of the first cell and a random access failure threshold of the first cell when the user equipment camps on the first cell;
• attempt to perform random access to the first cell, and count a quantity of random access failures;
• perform cell reselection by using the first signal offset for the first cell if the quantity of random access failures reaches the random access failure threshold;
• and
• perform cell reselection by using the first signal offset for the first cell when camping on a second cell if the second cell is selected to camp on in the cell reselection when camping on the first cell.

An electronic hardware set in a user equipment, the electronic hardware comprising:

• a processor, and a memory coupled with the processor;
• wherein the memory is configured to store instructions which, when executed by the processor, cause the user equipment to:
• receive the first signal offset of the first cell and a random access failure threshold of the first cell when the user equipment camps on the first cell;
• attempt to perform random access to the first cell, and count a quantity of random access failures;
• perform cell reselection by using the first signal offset for the first cell if the quantity of random access failures reaches the random access failure threshold;
• and
• perform cell reselection by using the first signal offset for the first cell when camping on a second cell if the second cell is selected to camp on in the cell reselection when camping on the first cell.
