Embodiment Construction

[0108] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0109] see figure 1 , figure 1It is a flow chart of the mobile robustness optimization method provided by the embodiment of the present invention. In this embodiment, the mobile robustness optimization process performed by the Femtocell controller may specifically include:

[0110] Step A1. Obtain the current moving speed and moving direction of the mobile UE.

[0111] Specifically, the femto base station controller may query the UE measurement state information table to obtain the current moving speed and moving direction of the mobile UE. In the example of the present invention, the change of the moving state of the mobile UE within the measurement report period is ignored, and the current moving speed and moving direction of the mobile UE are calculated according to the measurement position and time information of the last two measure...

Abstract

The invention discloses a mobile robustness optimization method and device based on mobile state information and adjacent region proximity and belongs to the technical field of wireless communication. In the method, a micro base station controller estimates real-time mobile state information of mobile UE according to cyclic measuring reports obtained from the mobile UE; then the mobile UE is subjected to switching control according to an adjacent region deploying environment, and frequent switching between a macrocell and a microcell of the mobile UE is avoided; and finally, during a switching process, switching preparing operation to a preparing target cell is brought forward, and according to the moving speed of the mobile UE and the PDCCH interruption point of the service microcell, the switching condition for avoiding ping-pong switching is computed. Compared with the prior art, the prediction success rate of the preparing target cell is improved, frequency spectrum resource using rate is improved, frequent switching between the macrocell and the microcell of the mobile UE is lowered, then network signaling expenditure is reduced, SToS rate is not increased, meanwhile, the switching success rate of the mobile UE can be improved, and then user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a mobile robustness optimization method and device based on mobile state information and neighboring cell proximity. Background technique [0002] With the wide-scale application of LTE technology, users have higher and higher requirements for data traffic. Traditional macro base stations have encountered bottlenecks in network construction and coverage. LTE-A heterogeneous small cell networks have emerged as the times require. The heterogeneous small cell network deploys low-power nodes in the coverage area of ​​the macro base station to absorb the hotspot area of ​​the macro network or cover its blind spot area, thus forming a heterogeneous system of different node types with the same coverage. Typical low-power nodes include pico base stations (Pico), home base stations (Femto), and relay base stations (Relay). According to the simulation results in 3GPP TR36.814...
