Problems solved by technology

[0011] However, with the introduction of relay stations and the improvement of people's requirements for existing networks, the existing air interface protocol architecture can no longer support the developing mobile communication network well, and many technical functions that cannot be supported appear, such as:
[0012] 1. Cannot support the function of the relay station;
[0013] 2. It cannot support the function of direct communication of data between users without passing through the

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] The core of the present invention is that, by modifying the protocol stack of the mobile communication system, functions related to relay are added in the MAC layer and the RRC layer respectively, so that the mobile communication system can use the relay station to realize the communication between the terminal and the terminal and between the terminal and the base station. communication between. In addition, a cooperative radio resource management (Cooperative Radio Resource Management, "CRRM") layer, an encryption sublayer, etc. are added to further improve various functions for the mobile communication system.

[0059] The system mentioned in the present invention refers to a wireless communication system, such as a 3G system, a post-3G (Beyond 3G, "B3G"...

Abstract

The invention relates to mobile communication field, discloses a mobile communication system and a mobile communication method, in condition of a mobile communication system comprising a relay station, the communication between terminals, a termial and a base station is normal. A Relay MAC function is added for the MAC layer, a simple relay can be realized; a Relay RRC function is increased in the RRC layer, a complex relay can be realized cooperating with Relay MAC. A physical layer supports various modes, such as FDD and TDD, a function of supporting various modes is added for the MAC layer, thereby the MAC layer can support access of terminals with various modes. The MAC layer supports point-to-point communication. A safe sublayer is added between the RRC layer and the MAC to improve communication safety. A cooperative radio resource management layer is also added on the RRC layer for coordinating and managing radio resources of different systems.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile communication system and a related communication method. Background technique [0002] With the development of human society, the requirements for mobile communication technology continue to increase and diversify, so the first to third generation mobile communication have appeared one after another. [0003] This leads to the existence of different wireless access technologies in the current mobile communication field, and thus the existence of wireless networks based on different technologies. Wireless networks based on different technologies include the Global System for Mobile Communication (GSM for short), Code Division Multiple Access (CDMA for short) in the second generation of mobile communications, and the third generation of mobile communications. Wideband Code Division Multiple Access (WCDMA for short), Time Division Synchronous Code Division Multiple Acce...
