Problems solved by technology

[0011] In the prior art, the wireless link failure of Pscell is not regarded as the MDT scenario, and the measurement data at this moment is not defined to be reported to the network back-end TCE (TraceCollection Entity) for MDT data collection, thus losing the network optimization data

Embodiment 1

[0038] When a radio link failure or SCG change failure occurs in the PSCell, the trigger for the radio link failure may be T313 timeout, random access failure, RLC reaching the maximum number of retransmissions, and SCG change failure. When a failure occurs, the UE records the type of failure, records the signal quality RSRP and RSRQ of the serving cell and its neighboring cells at this time, as well as the location information of the UE at this time, Pcell cell information, and starts a timer at the same time, from the measurement start to the measurement Report the stop timing and report the measurement time, which can be counted in seconds. For the wireless link failure scenario, record the cell information of the Pscell at the time of the failure. For the failure of the SCG change, record the cell information of the original cell and the target cell of the SCG change. The cell information here can be PCI and cell frequency point information, or global Cell identifier E-CGI...

Abstract

The present invention provides a method of optimizing network mobility. The method comprises the steps of measuring and recording the failure types, the signal quality of the service cell and adjacent cell signal quality, the position information, the time stamp information, the cell information and the Pcell information of an MeNB when a UE generates the wireless link failure or SCG change failure in a Pscell, then reporting to a network side to be used as the input data of the network side optimization. By utilizing the method of the present invention, the network optimization data under a DC scene can be collected by a commercial terminal, thereby perfecting the problems, such as the network optimization processing, the problem positioning, etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for network mobility optimization. Background technique [0002] With the development of wireless mobile communication technology, people put forward higher and higher requirements for high speed, low delay and low cost. The LTE (Long Term Evolution) project was born under such a background, pursuing higher peak rates and shorter transmission delays. [0003] The main performance goals of the LTE project include: providing a peak rate of 100 Mbps downlink and 50 Mbps uplink in a 20MHz spectrum bandwidth, improving the performance of cell edge users and increasing cell capacity; reducing system delay, and the one-way transmission delay within the user plane is less than 5ms. The transition time of the control plane from the sleep state to the active state is less than 50ms, and the transition time from the resident state to the active state is less than 100ms; it su...
