Embodiment 1

[0071] Make the indoor cell for indoor coverage work at two frequency points, among which only the indoor cell adjacent to the outdoor cell (for the convenience of description, hereinafter referred to as "transition cell") has the same operating frequency as the outdoor cell, and the other indoor cells The working frequency of the outdoor cell is different from the working frequency of the outdoor cell.

[0072] The schematic diagram of the working frequency of the cell is as follows: Figure 5 shown. The outdoor cell number is Cell0, and its operating frequency is f1. Figure 5 It is represented by Cell0-f1; the transitional cell number is Cell1, and its operating frequency is also f1, which is the same as the operating frequency of the outdoor cell base station. Figure 5 It is represented by Cell1-f1; the cell number of the indoor low-rise floor is Cell2, and its working frequency is f2, which is different from the working frequency of the outdoor cell. Figure 5 Indicat...

Embodiment 2

[0108] The indoor cells for indoor coverage adopt the same coverage mode of different frequency cells, and the working frequency of one of the cells covered by the same coverage is the same as that of the outdoor cell; the working frequency of the other cell covered by the same coverage is the same as that of the outdoor cell different.

[0109] The schematic diagram of the working frequency of the cell is as follows: Image 6 with Figure 7 shown. Image 6 Indicates the indoor coverage scheme when the building has fewer floors, where: the outdoor cell number is Cell0, and its working frequency is f1. Image 6 It is represented by Cell0-f1; the indoor cell number is Cell1, and its working frequency is f1. Image 6 Cell1-f1 is represented in it; another indoor cell with different frequency and same coverage is numbered Cell2, and its working frequency is f2. Image 6 Indicated by Cell2-f2.

[0110] Figure 7 Indicates the indoor coverage scheme when there are many floors ...

Abstract

The disclosed implementation method to cover in door for wireless signal in WCDMA system comprises: applying two work frequency points for target subzone with one same and another different as the outside subzone; when moving in the subzone of a terminal from outside subzone with different frequency point to current subzone, taking hard switch to one subzone in door. This invention can reduce interference, and increases switch success rate.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing indoor coverage of wireless signals in a Wide-band Code Division Multiple Address (WCDMA) access system. Background technique [0002] WCDMA technology is the most widely used technology in the third generation mobile communication technology. The WCDMA system is generally divided into three relatively independent equipment units: [0003] Radio Access Network (RAN), in which the Global Mobile Communication Terrestrial Radio Access Network is UTRAN; [0004] Core Network (CN); [0005] User equipment (User Equipment, UE). [0006] Among them, the radio access network is responsible for all wireless-related functions, the core network is responsible for switching or routing voice calls and data services to the external network, and the user equipment provides an operating platform for information exchange between users and network equipment. The int...
