Problems solved by technology

[0005] However, in the future 3G network deployment, the method of directly increasing network capacity by building more macro base stations is very costly: including site selection, equipment procurement, installation, commissioning and maintenance will consume a lot of manpower, financial resources, material resources and time
Therefore, it is obviously not a wise choice to simply use the macro cellular network to take into account both indoor and outdoor coverage.
For these residential areas, small and medium-sized office spaces, restaurants and coffee shops, etc., according to existing experience, if a dedicated indoor distribution system is used, it will bring problems in network design planning, installation and maintenance, and cost

Abstract

The invention relates to the technical field of wireless communication, in particular to a mobile communication base station based on IP self-adaptive TD-SCDMA (Time Division-Synchronization Code Division Multiple Access). The mobile communication base station is characterized by comprising a digital subsystem, a radio frequency subsystem, an antenna feeder subsystem, a clock subsystem and a power subsystem. The digital subsystem comprises an Iub interface and main control unit, a baseband processing unit, a clock unit and a zero intermediate frequency converting unit, wherein the Iub interface and main control unit is interconnected with a RAN (Radio Access Network) through an Iub interface and the antenna feeder subsystem is communicated with a user terminal through a Uu interface. The base station is not only beneficial to improving the indoor signal coverage quality of the TD-SCDMA network but also has low installing cost, convenient maintenance and good use effect.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an IP-based adaptive TD-SCDMA mobile communication base station. Background technique [0002] The development speed of mobile communication is astonishing. According to data from market research firm Informa at the end of 2007, there are 3.3 billion mobile users worldwide. Statistics from the former Ministry of Information Industry show that as of December 2007, the number of mobile phone users in China has reached 550 million. At present, the main commercial technologies of mobile communication are transitioning from 2G and 2.5G to 3G and HSPA. With the continuous improvement of the wireless access rate, the types of services are gradually evolving from pure voice and short message services to rich data services, and the ratio of mobile data services to the total number of services is also getting higher and higher. [0003] At the same time, the actual deploy...
