Parameter updating method and device for TD-LTE (Time Division Long Term Evolution) system

Abstract

The invention provides a parameter updating method and device for a TD-LTE (Time Division Long Term Evolution) system. The parameter updating method includes the steps of: obtaining cell determination identifiers and the scene distinguishing parameter of each cell; determining the cell scene type of each cell according to the scene distinguishing parameter of each cell; generating first correspondence between the cell determination identifiers and the cell scene types according to the cell determination identifiers and the cell scene types; generating third correspondence among the cell determination identifiers, parameters to be updated and parameter values according to the first correspondence and preset second correspondence among the parameters to be updated, the parameter values and the cell scene types; generating a parameter configuration file of eNBs (Evolved Node Base station) to be updated according to the third correspondence; and sending the parameter configuration file to the eNBs to be updated to allow each eNB to be updated to resolve the third correspondence from the parameter configuration file, and updating the parameter value corresponding to each parameter to be updated according to the respective cell determination identifier and the third correspondence. According to the parameter updating method and device, the maintenance cost of network can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for aligning parameters of a TD-LTE system. Background technique [0002] With the continuous development of TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution), a large number of base stations in the TD-LTE system need to be opened and maintained. -Activated base stations in the LTE system need frequent upgrades and update of parameter information. The upgrade of the base station is relatively mature for TD-LTE network or TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) network, but how to update the base station parameters in time is different; in TD- In the SCDMA system, each time the parameter information is updated, it is necessary to manually extract the original configuration data of the RNC (Radio Network Controller, wireless network controller), update the parameters offline, and then manua...

Problems solved by technology

Because in the TD-LTE network, the parameters of the eNB include not only all the parameters of the TD-SCDMA RNC but also the relevant parameters of the NB (Node B, base station) it manages, and because the number of eNBs in a city will be very large (at least there are Hundreds to thousands of units), if you still rely on professional technicians to update the parameter information, the time required will increase exponentially, which in turn will greatly increase the operation and maintenance cost of the TD-LTE network
