Embodiment Construction

[0059] Embodiments of the present invention provide a protocol stack architecture of a wireless communication system and an information interaction method thereof.

[0060] The schematic structural diagram of the protocol stack of the wireless communication system described in the embodiment of the present invention is as follows figure 2 shown. The structure of the protocol stack includes in order from top to bottom: CCM (Converged Control Management, Convergence Convergence Control Management) layer, abstraction layer, CLL (Convergence Link-layer, Convergence Link Layer) layer, access technology-specific L3 ( Layer 3), L2 (Layer 2) and PHY (Physical Layer, physical layer).

[0061] The detailed description of the functions of each layer of the above protocol stack is as follows:

[0062] CCM layer: Located at the top layer of the protocol stack, it is used to perform common control functions related to multiple access technologies. The control function at least includes:...

Abstract

The invention provides a method for protocol stack architecture and information interaction of a mobile communication system. The architecture consists essentially of a CCM (Common Control Management) layer, which is disposed on the uppermost layer of the protocol stack and used for implementing a plurality of common controls related to RAT (Radio Access Technology); generating a decision result according to the types of received general event type or of the information and sending the result to a lower layer; and an abstract layer which is used for shielding the difference between various RATs of the lower layer, transforming various types of required RAT information into a general event type or an information type for reporting to an upper layer, and sending the received decision result to the lower layer corresponding to various RATs. The invention solves the problem that the architecture of the protocol stack is not definite in an environment where a plurality of access technologies coexist.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a structure of a protocol stack of a wireless communication system and an information interaction method thereof. Background technique [0002] With the rapid development of high-speed network technology and multimedia technology, the development of wireless network is very fast. Wireless network gradually evolves from circuit switching to packet switching, and various wireless broadband access technologies emerge in endlessly. At present, the main wireless networks are GSM (Global System for Mobile, Global System for Mobile Communications), GPRS (General Packet Radio Service, General Packet Radio Service), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), CDMA ( code division multiple access, code division multiple access) 2000, WiMAX (Worldwide Interoperability Microwave Access, global interoperability of microwave access), B3G...
