TD-SCDMA mobile communication method and TD-SCDMA wireless indoor base station

Abstract

The invention discloses a TD-SCDMA mobile communication method and a TD-SCDMA wireless indoor base station. The TD-SCDMA mobile communication method is as follows: a TD-SCDMA wireless indoor base station is arranged indoors; the TD-SCDMA wireless indoor base station is accessed to a mobile wireless network controller or a core network through wired network transmission medium. By realizing indoorcoverage for TD-SCDMA wireless signals through the TD-SCDMA wireless indoor base station, communication with a TD-SCDMA mobile terminal is realized. The method integrates the wired communication technology and the wireless communication technology and adopts the TD-SCDMA wireless indoor base station to provide a good signal coverage and sufficient frequency resource for a subscriber, and to support the high speed and broadband wireless access of the subscriber; the method also supports the transmission of the high speed or broadband data through the wired communication technology.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a TD-SCDMA mobile communication method, and also relates to a mobile communication base station, especially a TD-SCDMA wireless indoor base station for TD-SCDMA mobile communication. Background technique [0002] According to the regulations of the ITU (International Telecommunication Union), the third generation mobile communication system (3G) works at a frequency of 2000MHz or above. Due to the higher operating frequency and shorter wavelength than the second generation mobile communication system (2G), the radio wave Therefore, how to effectively achieve the effective signal coverage of the third-generation mobile communication system has brought challenges to users to provide third-generation mobile communication services anytime and anywhere; secondly, The third generation of mobile communication requires to provide users with high-speed, broadband wireless m...

AI Technical Summary

Problems solved by technology

[0005] 1. The construction cost is very expensive: adding base stations, adding trunk lines, and choosing a suitable site and renting the site for the base station;

[0006] 2. Difficulty in actual engineering installation: E1 or E1 combined trunk lines need to be laid

[0007] 3. The addition of base stations brings challenges to frequency planning and effective suppression of system interference, especially when the TD-SCDMA system supports high-speed downlink packet access (HSDPA) services, due to the possible use of asymmetric time slots, adjacent cells and cells, or sector Saturation, congestion and interference between zones and sectors will seriously affect system performance

[0008] 4. Simultaneously increasing the transmit power of the base station will bring hidden dangers to the health of users

[0009] 5. Wireless resources are still the bottleneck when the public base station supports multiple high-speed data service users;

Instead of providing spectrum resources other than the wireless resources of the original mobile communication network

Therefore, the current mobile communication indoor distribution system only solves the coverage problem, but does not solve the problem of wireless resources and capacity, and cannot meet the needs of users for wireless high-speed and broadband data services.
