Problems solved by technology

[0007] In the prior art, two non-access stratum processes are used at the same time: tracking area update and non-access stratum security mode command, which causes unnecessary signaling load to the communication system and unnecessary delay to the communication process. reduced system performance

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] figure 1 The flow chart of enabling the local security context after switching between systems for the present invention includes:

[0031] Step 102, the UE sends a tracking area update request message to the MME, and uses the mapped security context to protect the integrity of the message. If the UE has a local security context, the message contains the KSI corresponding to the local security context ASME (Key Set Identifier of Access Security Management Entity, access security management entity key identifier).

[0032]The message also carries the UE's GUTI (Globally Unique Temporary Identity, Globally Unique Temporary Identity), GUTI is the UE's unique t...

Abstract

The invention provides a method for enabling a local security context, which comprises the following steps that user equipment (UE) sends a tracking area updating request information to a mobility management entity (MME), and when the MME knows that the MME and the UE share the local security context which corresponds to the key switch-in access security management entity (KSIASME) and the global unique temporary identification (GUTI), the MME enables the local security context which corresponds to the KSIASME and the GUTI. The invention improves the tracking area updating process, has the function of enabling the local security context so as to be in a non-access stratum from switch flow among systems and remove the security mode command procedure of the non-access stratum, thereby achieving the effects of alleviating signaling traffic of systems, reducing communication delay and optimizing the communication process.

Description

technical field [0001] The invention relates to the technique of enabling a security context in the communication field, in particular to a method for enabling a local security context when switching between different systems. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3GPP) is composed of the Evolved UMTS Terrestrial Radio Access Network (EUTRAN) and the EPS Evolved Packet core network (Evolved Packet Core, EPC for short). EPC can support users from Global System for Mobile Communication Enhanced Data Rate for GSMEvolution radio access network (GERAN for short) and Universal Terrestrial Radio Access Network (Universal Terrestrial Radio Access Network) Network, referred to as UTRAN) access. [0003] The EPC packet core network includes a Mobility Management Entity (MME for short), and the MME is responsible for mobility management, non-access stratum signaling processing, and user security mode management and ot...
