RRC (Radio Resource Control) state machine realization method and device

Abstract

The invention discloses a RRC (Radio Resource Control) state machine realization method and a device. According to complexity of a RRC layer protocol stack and a mutual relationship between related processes, for each function process possibly causing changes of four basic states, each trigger sub state executed by the process is added, processing and judgment on a received corresponding message during each process is thus controlled, operation of the protocol stack is managed via a single thread, and the protocol stack can be ensured to operate high efficiently and stably. Correspondingly, corresponding to the above realization method, the invention also provides a RRC state machine realization device, which comprises a recording unit, a receiving unit, a callback unit and an execution unit. Problems of much resource consumption, complicated operation and maintenance when the protocol stack operates and is developed can be solved, complexity of the state machine is simplified, and high efficiency and stability of system operation can be ensured.

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...
