Cell switching control method, user equipment and radio network controller

Abstract

The invention provides a cell switching control method. An RNC (radio network controller) distributes a first cofrequency event report threshold and/or a second cofrequency event report threshold. UE (user equipment) sends a first measurement report message to the RNC according to RSCP of a cofrequency adjacent cell of a present cell, the first cofrequency event report threshold and a first cofrequency event retardation parameter. The UE sends a second measurement report message to the RNC according to the RSCP of the cofrequency adjacent cell of the present cell, the second cofrequency event report threshold and a second cofrequency event retardation parameter. The RNC controls switching between cells according to the first measurement report message and/or the second measurement report message. The invention also provides the UE and the RNC. By employing the cell switching control method, the UE and the RNC provided by the invention, only when the communication quality of the cofrequency adjacent cell of the present cell is higher than an absolute threshold, reporting is triggered, that the communication quality of a switched cell is in accordance with a communication requirement is ensured, and cell switching success rate is raised.

Description

Technical field [0001] The embodiment of the present invention relates to a mobile communication technology, in particular to a cell handover control method, a user equipment (User Equipment, U E) and a radio network controller (Radio Network Controller, RNC). Background technique [0002] In the mobile communication network system, various handover procedures are triggered according to the measurement report. In the 3rd Generation Partnership Project (3GPP) communication system, the measurement of the downlink physical channel of the same frequency in the current cell is called co-frequency measurement. In the process of co-frequency measurement, one measurement object corresponds to A community. [0003] At present, the reported events of the same frequency measurement are 1G events. The trigger condition for reporting 1G event is: 10·LogM i +O i -H 1g >10·LogM previous_best +O previous_best , Where M i To measure the received signal code power (Received Signal Code Power, R...

Problems solved by technology

With this method, the communication quality of the cell after switching is better than that of the cell before switching. However, as long as the communication quality of the cell after switching is higher than that of the cell before switching by a certain value, a 1G event will be reported. Therefore, it is possible that the cell after switching Although the communication quality of the cell is better than a certai
