Device and method for realizing non access stratum in wireless communication system

Abstract

The invention provides a method and a device for realizing a non access stratum in a wireless communication system. The device comprises an event controller, an event handler, an event manager, a data manager, a timer manager, a message constructing and resolving device, and a safety manager, wherein the control center of the whole system event managing device of the event manager triggers the event controller, initializes the data manager and the timer manager and manages the non access stratum event; the event controller controls the event handler; the specific handling processes of the event handler on different events of the non access stratum are mainly divided into mobility management, conversion management and connection control management; the message constructing and resolving device resolves or constructs the non access stratum message, and the information is supplied for the event controller to be handled; the safety manager encrypts and deciphers the message, and protects and verifies the integrity of the message; the timer manager is used for providing and maintaining the management of the timer; and the data manager is used for maintaining the data manager of the overall situation information in the non access stratum system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the third generation and the non-access layer of the LTE mobile communication system. Background technique [0002] The future mobile communication network will develop in the direction of broadband, packetization, and flattening. While meeting diversified communication requirements, it is necessary to greatly increase the capacity of the mobile communication system and reduce network costs. LTE (Long Term Evolution, long-term evolution plan) is a technical standard formulation plan implemented by the 3GPP standardization organization since 2004. Its goal is to form a wireless access technology with high data rate, low delay and optimized packet transmission capability , referred to as E-UTRAN or LTE. The physical layer of the LTE system realized according to the LTE standard adopts OFDMA technology and MIMO technology based on OFDM, so that the downlink data transmission ...

AI Technical Summary

Problems solved by technology

[0004] In view of the technical difference between the LTE standard and the existing communication standard, the non-access stratum implementation method in the existing communication standard cannot be directly applied to the LTE standard

The LTE standard itself is a new thing, so there is no implementation method for the non-access stratum in LTE in the prior art.
