A method and device for implementing an rrc state machine

Abstract

The invention discloses a method and device for realizing an RRC state machine. According to the complexity of the RRC layer protocol stack and the interrelationships of the processes involved, for each functional process that may cause four basic state changes, the process execution is added. The various trigger sub-states of each process are used to control the processing and judgment of the corresponding messages received in each process, and the operation of the protocol stack is managed through a single thread to ensure the efficient and stable operation of the protocol stack; correspondingly, corresponding to the above implementation method , the present invention also proposes an RRC state machine implementation device, which includes a recording unit, a receiving unit, a callback unit and an executing unit. The invention solves the problems of high resource consumption and complicated operation and maintenance during the development and operation of the protocol stack, simplifies the complexity of the state machine, and ensures the high efficiency and stability of the system operation.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a method and a device for realizing an RRC state machine. Background technique [0002] RRC (Radio Resource Control, Radio Resource Control) is a layer 3 control plane protocol, which is the actual carrier of the control plane functions of the air interface part of the protocol stack in the GMR-1 3G system, and is responsible for the execution of the air interface radio link process. Mainly responsible for radio resource allocation and management, system message broadcast, paging, RRC connection establishment and release, RRC connection mobility management (cell update, GRA update), RB management, NAS layer message delivery, measurement control, encryption, etc. [0003] The RRC layer is mainly divided into an idle state and a connected state, and the connected state is subdivided into three states: RRC-Cell_Shared, RRC-Cell_Dedicated and RRC-GRA_PCH. In the RRC...
