Embodiment Construction
[0081] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0082] In the prior art, the source base station only sets the handover cell information according to the measurement data reported by the UE. If the UE cannot successfully access the target cell and performs re-establishment, re-establishment failure may occur.
[0083] In addition to setting the handover cell information according to the measurement data reported by the UE measurement, the present application can also obtain the neighbor cells of the first handover cell from the neighbor cell relationship table, and can add more cells to the cell set of the base station. Therefore, when the user equipment fails to successfully access the target cell and performs re-establishment, the problem of re-estab...

The invention provides a preprocessing method and a preprocessing device for cell handover in a long term evolution (LTE) system, and aims to solve the problems of failures in the reestablishment process of the cell handover. The method comprises the following steps of: receiving measurement data from user equipment, wherein the measurement data comprises first handover cells; acquiring base stations of the first handover cells to form a base station set, and dividing the first handover cells according to the base stations to form base station cell sets, wherein one base station at least comprises one first handover cell; acquiring neighbor cells of the first handover cells in the measurement data in a neighbor cell relationship table, and adding the neighbor cells into corresponding base station cell sets as second handover cells, wherein the neighbor cell relationship table comprises the first handover cells and the neighbor cells of the first handover cells; and transmitting a handover request to the base stations in the base station set, wherein the handover request comprises the context information of the user equipment. The problems of reestablishment failures can be effectively reduced.
Description
technical field [0001] The present application relates to the technical field, in particular to a preprocessing method and device for cell handover in an LTE system. Background technique [0002] In a mobile communication system, when a UE (User Equipment) in a communication state moves from one cell to another, or the link quality of the serving cell deteriorates, in order to ensure the continuity of communication, the network needs The UE is handed over to another cell, and the other cell continues to provide services for the UE. [0003] When performing cell handover, the source base station sets the information of the handover cell according to the measurement data reported by the UE measurement, and the handover cell can be composed of several base station cell sets according to the base stations to which it belongs, wherein the source base station is the cell to which the UE is located before handover base station. [0004] In order to improve the handover success ra...
