Embodiment 1

[0075] In this embodiment, the attached request sent by the UE to the MME carries an encrypted PCO transmission flag. The main process of this embodiment is as Figure 5 As shown, it mainly includes the following processing:

[0076] Step S502: The UE sends an attach request message to the MME, which includes all security capabilities of the UE, and also carries an encrypted PCO transmission flag, which is used to inform the MME that the PCO needs to be transmitted encrypted.

[0077] Step S504: After receiving the attach request message from the UE, the MME performs authentication and key negotiation with the UE.

[0078] Step S506: After the MME performs integrity protection on the NAS security mode command message, it sends the NAS security mode command message to the UE, and the message carries the NAS security algorithm, KSI and PCO request flag selected by the MME, wherein the PCO request flag uses It is used to instruct the UE to carry the PCO information in the subse...

Embodiment 2

[0085] In this embodiment, the attached request sent by the UE to the MME does not carry the encrypted PCO transmission flag. The main process of this embodiment is as Image 6 As shown, it mainly includes the following processing:

[0086] Step S602: the UE sends an attach request message to the MME, and the message includes all security capabilities of the UE.

[0087] Step S604: After receiving the attach request message from the UE, the MME performs authentication and key negotiation with the UE.

[0088] Step S606: The MME sends a NAS security mode command message to the UE, and the message carries the NAS security algorithm and KSI selected by the MME.

[0089] Step S608: After receiving the NAS security mode command message from the MME, the UE uses the NAS security algorithm, KSI and other information carried by the MME in the NAS security mode command message to establish a NAS security association with the MME.

[0090] Step S610: The UE carries PCO information in...

Abstract

The invention provides a protocol arrangement option transmitting method, a system and a user terminal, wherein, after the user terminal receives non-access layer security mode command information transmitted by a mobile managing entity, the user terminal transmits non-access layer security mode completion information to the mobile managing entity. The non-access layer security mode completion information is carried with the protocol arrangement option. The mobile managing entity obtains the protocol arrangement option from the non-access layer security mode completion information. According to the technical scheme provided in the invention, signalling alternation between the user terminal and the mobile managing entity is reduced, and waste of network resource is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a protocol configuration option transmission method and system, and a user terminal. Background technique [0002] System Architecture Evolution (SAE for short) is the next generation mobile wireless network of the 3rd Generation Partnership Project (3GPP for short). In the SAE system, the Mobility Management Entity (Mobility Management Entity, short for Functions such as mobility management and session management are implemented between the MME) and the user equipment (User Equipment, UE for short) through Non-Access Stratum (Non-Access Stratum, NAS for short) messages. [0003] In order to ensure the safe transmission of NAS messages and increase the security function of NAS messages, the security function of NAS messages is added to the SAE system, that is, to encrypt and protect the integrity of NAS messages. The purpose of encryption is to prevent NAS messages f...
