Problems solved by technology

In addition to RAN area update, the UAC mechanism of 5G and eLTE may also support the ACB of the signaling generated by the terminal in the connected state, such as the establishment of the protocol data unit (PDU, Protocol Data Unit) session initiated by the connected state UE and the ACB of the modification signaling, And connected state UE may need to perform ACB on the user plane for different quality of service flows (QoS flow), access control triggered by the access layer (AS) is a problem that both NR and eLTE must solve
[0007] The problem of the existing technology is that for eLTE, MSG3 is difficult to expand. Compared with the traditional ACB mechanism, how to support the access control of the access attempt triggered by the emerging AS is a problem to be solved

Embodiment Construction

[0093] The current mechanism performs access control based on the access category and establishment cause provided by the NAS layer, and cannot solve the ACB of the access attempt triggered by the AS. This is because 1) NAS does not perceive events triggered by AS; 2) the size of MSG3 cannot meet the scalability requirements of UAC.

[0094] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with specific embodiments. The following schemes of the embodiments of the present invention include two cases of extending the length of MSG3 and not extending the length of MSG3. Therefore, the schemes of the embodiments of the present invention are applicable to both eLTE and 5G NR. In addition, for the case where the length of MSG3 is not extended, the solution in the embodiment of the present invention is not limited to eLTE, and can also be applied to other types of communication systems, such as LTE.

Abstract

The invention discloses an access control method and a device thereof and a computer storage medium. The method comprises the steps that an AS layer informs an NAS layer of access attempt triggered byan AS; the NAS layer determines an access core corresponding to the access attempt, and allocates a reason value to the access core corresponding to the access attempt; and the NAS layer informs theAS layer of the access control corresponding to the access attempt and the reason value of the access control corresponding to the access attempt.

Description

[0001] This application is a PCT international patent application PCT / CN2018 / 080546 with a filing date of March 26, 2018. The Chinese patent application number 201880066648.5 entered the Chinese national phase, and the title of the invention is "a method and device for access control, computer storage medium" Divisional application. Technical field [0002] The present invention relates to the field of wireless communication technology, in particular to an access control method and device, and a computer storage medium. Background technique [0003] Access control is the Long Term Evolution (LTE) system and the fifth generation (5G, 5 th The basic function of the Generation) system is mainly to control the number and frequency of connections initiated by the terminal according to the load of the network to avoid overloading the network. [0004] In the 5G New Radio (NR, New Radio) system and the enhanced Long Term Evolution (eLTE, enhanced Long Term Evolution) system, it is necessar...
