Embodiment Construction

[0035] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] The basic idea of ​​the present invention is: the UE side analyzes the specific cause of RLF or handover failure and reports it to the eNB, so that the eNB can adjust the handover parameters.

[0037] The RLF is a radio link failure, and if the RLF occurs or the handover fails, the RRC connection re-establishment process will be further performed. At the same time, the occurrence of RLF in the handover process will also lead to handover failure, and then the RRC connection re-establishment process will occur. The RRC connection re-establishment process in this case is regarded as being caused by RLF in the present invention, and it can certainly be regarded as being caused by handover. The specific reasons for the RRC connection reestablishment process caused...

Abstract

The invention provides a switching parameter adjusting method. The switching parameter adjusting method comprises the following steps that: a UE (User Equipment) determines the time relationship between an RLF or switching failure happened and a switching process when the RLF or the switching failure happen, the UE determines reasons for the RLF or switching failure according to the time relationship and reports the reasons to an eNB, and the eNB which have received the reasons adjusts a switching parameter according to the reasons. According to the switching parameter adjusting method provided by the invention, specific reasons are analyzed by the UE according to the time of the RLF or switching failure, and specific reason information is directly reported to the eNB, so that the eNB can acquire accurate reasons for an RRC reconnection caused by the RLF or the switching failure, and therefore the switching parameter can be adjusted more accurately according to the accurate reasons.

Description

technical field [0001] The invention relates to handover technology in a communication system, in particular to a handover parameter adjustment method. Background technique [0002] As data services are more and more widely used, and users' demand for data rates is increasing, the traditional network architecture based on cellular coverage can no longer meet the needs of service characteristics. In the LTE-Advanced system, research on heterogeneous networks has been carried out to more fully meet the requirements of various business characteristics. [0003] In an LTE-Advanced system, a network composed of cells with different transmission powers and different backhaul link types is called a heterogeneous network. Some cells are used to expand the coverage of cell edges or blind spots, some cells are used to increase the capacity of hot spots, and some cells are used to provide better service quality for home users. Different types of cells often have different transmit po...
