<p>The invention relates to a method of optimizing a radio link monitoring window parameter in a user equipment of a radio heterogeneous communication network, the radio heterogeneous communication network including a macro cell and a small cell, the method including the steps of: receiving a first radio link monitoring window parameter and a second radio link monitoring window parameter from an e NB of the macro cell; using the first parameter below the second parameter as the radio link monitoring window parameter; determining whether the user equipment is close to the small cell; and if a determination result is negative, then continuing the use of the first parameter as the radio link monitoring window parameter, or if the determination result is positive, then using the second parameter as the radio link monitoring window parameter. The user equipment uses a third parameter obtained from an e NB of the small cell as the radio link monitoring window parameter after being handed over to the small cell. All these three parameters are related to the motion speed. With the solution of the invention, different time values of radio link invalidation can be set for different scenarios in a heterogeneous network to thereby improve mobility performance.</p> |
