Embodiment Construction

[0082] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0083] In 5G NR mobile communication technology, the connection between a terminal device and a data network (data network, DN) for data transmission is called a PDU session. According to the different requirements of applications for sessions, a terminal device can establish multiple PDU sessions at the same time to transmit data of different app...

Abstract

The embodiment of the invention provides a protocol data unit session management method and a communication device. A core network device generates an NAS message containing an indication domain and sends the NAS message to a terminal device, the indication domain is used for indicating whether the number of PDU sessions of the terminal device is limited, and the terminal device determines whethera new PDU session can be established according to the indication domain. By adopting the scheme, the technical scheme is adopted, the terminal equipment in a normal service state can determine whether the number of PDU sessions is limited or not through the NAS message; the limitation of Maximum number over stablished PDU session is broken through without turning on or turning off the terminal equipment or plugging in or pulling out an SIM card, the process is simple, and the normal service of the terminal equipment can be prevented from being interrupted.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communication, and in particular relates to a protocol data unit session management method and a communication device. Background technique [0002] Currently, the Third Generation Partnership Project (3GPP) has set up a research project (study item, SI) on the fifth generation (5th-Generation, 5G) communication technology: enhanced wireless broadband (enhanced mobile broadband, eMBB), ultra-reliable low-latency communications (URLLC) and massive machine type communications (mMTC). [0003] A session (session) is a connection between a user equipment (User Equipment, UE) and a data network (datanetwork, DN), and is used to transmit data between the UE and the data network. In 5G new air interface (new radio, NR), A session is collectively referred to as a protocol data unit (Protocol Data Unit, PDU) session. According to different requirements of applications (applications, A...
