Method, apparatus and system and storage medium for re-establishing radio resource
First Claim
1. A method for re-establishing radio resource(s), comprising:
- when a terminal triggers re-establishing of the radio resource(s), sending a request indication message, wherein the request indication message is arranged to request for acquiring a first Packet Data Unit (PDU) number, which is recorded by a target evolved Node B until the request indication message is received, of PDUs which have been transmitted between the terminal and the target evolved Node B;
receiving, by the terminal, a response message sent by the target evolved Node B, wherein the response message carries the first PDU number;
comparing, by the terminal, a second PDU number, which is locally maintained, with the first PDU number to acquire a difference value between the second PDU number and the first PDU number; and
when the difference value does not exceed a preset threshold value, determining, by the terminal, that the target evolved Node B is a legal evolved Node B, and implementing, by the terminal, re-establishing of the radio resource(s) between the terminal and the target evolved Node B, wherein the second PDU number is a second PDU number, which is recorded by the terminal until the response message is received, of PDUs which have been transmitted between the terminal and the target evolved Node B.

Abstract
The embodiments of the disclosure disclose a method, apparatus and system, and a storage medium for re-establishing radio resource(s). The method may include: when a terminal triggers re-establishing of the radio resource(s), a request indication message is sent by the terminal; the terminal receives a response message sent by a target evolved Node B; the terminal compares a second Packet Data Unit (PDU) number which is locally maintained with a first PDU number to acquire a difference value between the second PDU number and the first PDU number; and when the difference value does not exceed a preset threshold value, the terminal determines that the target evolved Node B is a legal evolved Node B, and the terminal implements re-establishing of the radio resource(s) between the terminal and the target evolved Node B.
