Problems solved by technology

However, because the life cycle of GSM is much longer than expected, the breakthrough of Software Defined Radio (SDR) technology is slow, and the multi-mode base station based on SDR technology is far from meeting the needs of operators.

Embodiment Construction

[0016] The radio base station equipment may be divided into a radio equipment controller (Radio Equipment Controller, REC for short) and a radio equipment (Radio Equipment, RE for short). The interface connecting the REC and the RE may be referred to as a REC-RE interface.

[0017] The Common Public Radio Interface (CPRI for short) standard is an interface standard between RECs and REs formulated by communication equipment manufacturers. In this standard, the REC-RE interface connecting REC and RE is called CPRI interface.

[0018] The Open Base Station Architecture Initiative (OBSAI for short) standard is another interface standard between the REC and the RE developed by a communication equipment manufacturer. In this standard, the REC-RE interface connecting REC and RE is called OBSAI interface.

[0019] RECs of different standards may include: main control clock module, baseband processing module, baseband radio frequency interface module, etc. These functional modules o...

Abstract

The invention discloses a radio communication system, which comprises radio communication equipment. The radio communication equipment comprises radio equipment (RE) supporting at least two communication modes and a radio equipment controller (REC) supporting at least two communication modes; the RE comprises at least two REC-RE interfaces; at least two REC-RE interfaces transmit different communication modes of datum, and the number of the REC-RE interfaces corresponds to the number of supporting communication modes; REC comprises at least two REC-RE interfaces which correspond to the at least two REC-RE interfaces of the RE; and at least two REC-RE interfaces of the RE are connected with the REC-RE interfaces corresponding to the identical communication modes of the REC by a wire cable. In the embodiment of the invention, the REC-RE interfaces are relatively independent, and the realization of the clock synchronization processing in the communication system can be omitted, so that an effect of realizing multi-mode solving proposal easily and at low cost is achieved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication system, a wireless device controller and a wireless device. Background technique [0002] With the rapid development of wireless network technology, in order to protect the investment of operators and reduce the risks brought by market changes, the industry has proposed the concept of multi-mode base stations. An expression of the concept of a multi-mode base station is: a base station that simultaneously supports two or more communication standard applications in one cabinet. [0003] The main advantages of multi-mode base stations are: [0004] (1) The base station equipment can be reused, including the reuse of hardware platform and software architecture; [0005] (2) It can reduce repeated installation of equipment and reduce site space; [0006] For example, the concept of GSM / UMTS dual-mode base station emerged in the late 1990s with the gra...
