Problems solved by technology

[0019] In practical application, the above scheme has the following problems: in some application environments, such as remote mountainous areas with steep terrain, closed building spaces, etc., due to the difficulty of laying lines, it is difficult to implement the distributed architecture of the entire base station system, or It takes a lot of manpower and material resources to set up, which seriously hinders the improvement of mobile communication network coverage
[0020] The main reason for this situation is that the connection links between the various functional entities of the base station subsystem are all wired links, which can only be realized by physical laying, and in order to cover the entire cell range, it is necessary to make each The functional entity parts are separated from each other, which leads to difficulties in the laying of wired links and the realization of base station subsystems

Embodiment Construction

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The basic idea of ​​the present invention is to improve the wireless communication based on the existing service carrier frequency into the transmission carrier frequency, establish a wireless link to replace the current wired link, avoid problems such as line laying, and conveniently realize the formation and assembly of the GSM base station system. network. The base station subsystem includes two transmission carrier frequencies and related equipment. The transmission carrier frequencies are two ends of a wireless link, which belong to two functional entities of the BSS, and the link realizes wireless communication between the two functional entities. The "carrier frequency" in this article refers to the functional modules or devices related to data tr...

Abstract

This invention discloses a sub-system of a mobile communication base station and a method for transmitting data to realize quick and flexible networking, in which, the communication links among functional entities of the base station system are realized by the radio links among transmission carrier frequencies which are realized by simple improvement on the basis of original service carrier communication links.

Description

technical field [0001] The present invention relates to a mobile communication base station subsystem, in particular to a mobile communication base station subsystem implemented based on wireless transmission. Background technique [0002] The Global System for Mobile Communications ("GSM" for short) is the second-generation cellular mobile communication system, and the world's first digital cellular mobile communication system that standardizes digital modulation methods, network structures and service types. The services provided by GSM are divided into voice services, bearer services, supplementary services and short message services. The GSM system adopts a Subscriber Identify Module ("SIM" for short). A SIM card is a memory in which user-related information such as a user identification code, authentication and encryption information, and a 4-digit personal identification code is stored. The user can obtain the system service on any GSM terminal through the SIM card. ...
