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] Embodiments of the present invention relate to mobile communication technologies, and in particular to a cell handover control method, a user equipment (User Equipment, UE for short), and a radio network controller (Radio Network Controller, RNC for short). Background technique [0002] In a mobile communication network system, various handover procedures are triggered according to measurement reports. In the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 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, a measurement object corresponds to a community. [0003] Currently, the reported events for co-frequency measurement are 1G events. The trigger condition for reporting 1G events is: 10 LogM i +O i -H 1g >10·LogM previous_best +O previous_best , where M i ...

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 certain value of the cell before the handover, the communication quality of the cell still cannot realize normal communication, which will lead to multiple consecutive handovers of the same frequency, resulting in a low handover success rate of the same-frequency handover cell, thus giving the receiving Negative impact on key performance indicators of the communication system such as incoming success rate and call drop rate
