Embodiment Construction

[0032] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0033] In the related art, based on the description in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) agreement, the user equipment (User Equipment, UE) needs to initiate the PDN in the Mobility Management (EPS Mobility Management, EMM) registered state (REGISTERED) connection, but there is no detailed description for other states of the EMM, so that ...

Abstract

The invention relates to a packet data network connection method and device and a storage medium. The packet data network connection method comprises the following steps: responding to a packet data network PDN connection request which needs to be sent by user equipment in a tracking area update TAU process; and delaying sending of the PDN connection request. According to the method and the device, the EMM state when the PDN connection request is sent in the TAU process is determined, and the PDN connection request is subjected to delayed sending processing, so that the success rate of PDN connection in the TAU process is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a packet data network (Packet Data Network, PDN) connection method, device and storage medium. Background technique [0002] Based on the description in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) agreement, the user equipment communicates through a PDN connection. [0003] In related technologies, a user equipment may initiate a PDN connection during a tracking area update (Tracking Area Update, TAU) process. However, the PDN connection request sent during the TAU process may be rejected, and the PDN connection fails. Contents of the invention [0004] In order to overcome the problems existing in related technologies, the present disclosure provides a packet data network connection method, device and storage medium. [0005] According to a first aspect of an embodiment of the present disclosure, a packet data netwo...
