Method and apparatus for switching a transmission route of data in wireless communication system

A node in a wireless communication system, the node comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• configuring the node with a first radio link and a second radio link;
• receiving, from a network, information including a first threshold for switching a transmission route from the first radio link to the second radio link;
• and
• based on a number of random access channel (RACH) preambles transmitted to the first radio link being equal to or exceeding the first threshold, transmitting a RACH preamble to the second radio link.

An apparatus for a node, the apparatus comprising:

• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• configuring the node with a first radio link and a second radio link;
• receiving, from a network, information including a first threshold for switching a transmission route from the first radio link to the second radio link;
• and
• based on a number of random access channel (RACH) preambles transmitted to the first radio link being equal to or exceeding the first threshold, transmitting a RACH preamble to the second radio link.

A computer readable storage medium storing at least one computer program comprising instructions that, when executed by at least one processor, cause the at least one processor to perform operations for a node, the operations comprising:

• configuring the node with a first radio link and a second radio link;
• receiving, from a network, information including a first threshold for switching a transmission route from the first radio link to the second radio link;
• and
• based on a number of random access channel (RACH) preambles transmitted to the first radio link being equal to or exceeding the first threshold, transmitting a RACH preamble to the second radio link.
