Random access method, terminal, and network device

A terminal, comprising:

• a processor;
• a memory;
• and
• a computer program stored in the memory and capable of running on the processor, wherein the computer program, when executed by the processor, causes the processor to implement a random access method comprising:
• receiving first resource configuration information sent by a network device, wherein the first resource configuration information is used to indicate M first frequency resources and N second frequency resources, and M and N are positive integers greater than or equal to 1;
• sending a random access request on a target first frequency resource to the network device;
• and
• receiving a random access response sent by the network device on a target second frequency resource, wherein the target first frequency resource is a free frequency resource in the M first frequency resources, and the target second frequency resource is a free frequency resource in the N second frequency resources,
• wherein before sending the random access request on the target first frequency resource to the network device, the method further comprises:
• monitoring some or all first frequency resources in the M first frequency resources;
• and
• when the terminal detects that Y first frequency resources in the some or all first frequency resources are free, using at least one of the Y first frequency resources as the target first frequency resource, wherein Y is less than or equal to a quantity of the some or all first frequency resources, and Y is a positive integer greater than or equal to 1,
• wherein monitoring some or all first frequency resources in the M first frequency resources comprises:
• monitoring the some or all first frequency resources in the M first frequency resources according to a first predetermined rule;
• and
• using at least one of the Y first frequency resources as the target first frequency resource comprises:
• selecting at least one of the Y first frequency resources as the target first frequency resource according to a second predetermined rule, wherein
• the first predetermined rule comprises at least one of the following:
• first frequency resources satisfying a first condition are monitored, and a quantity of monitored first frequency resources is less than or equal to a first threshold;
• and
• the second predetermined rule comprises at least one of the following:
• first frequency resources satisfying the first condition are selected, or a quantity of selected first frequency resources is less than or equal to a third threshold;
• wherein the first condition is that a frequency measurement value corresponding to the first frequency resource is greater than or equal to a second threshold, the first threshold is less than or equal to M, and the third threshold is less than or equal to Y.

A non-transitory computer-readable storage medium, storing a computer program that, when executed by a processor, causes the processor to implement a random access method, and the random access method comprises:

• sending a random access request on a target first frequency resource to the network device;
• and
• receiving a random access response sent by the network device on a target second frequency resource, wherein the target first frequency resource is a free frequency resource in the M first frequency resources, and the target second frequency resource is a free frequency resource in the N second frequency resources,
• wherein before sending the random access request on the target first frequency resource to the network device, the method further comprises:
• monitoring some or all first frequency resources in the M first frequency resources;
• and
• when the terminal detects that Y first frequency resources in the some or all first frequency resources are free, using at least one of the Y first frequency resources as the target first frequency resource, wherein Y is less than or equal to a quantity of the some or all first frequency resources, and Y is a positive integer greater than or equal to 1,
• wherein monitoring some or all first frequency resources in the M first frequency resources comprises:
• monitoring the some or all first frequency resources in the M first frequency resources according to a first predetermined rule;
• and
• using at least one of the Y first frequency resources as the target first frequency resource comprises:
• selecting at least one of the Y first frequency resources as the target first frequency resource according to a second predetermined rule, wherein
• the first predetermined rule comprises at least one of the following:
• first frequency resources satisfying a first condition are monitored, and a quantity of monitored first frequency resources is less than or equal to a first threshold;
• and
• the second predetermined rule comprises at least one of the following:
• first frequency resources satisfying the first condition are selected, or a quantity of selected first frequency resources is less than or equal to a third threshold;
