Embodiment 1

[0108] Such as image 3 As shown, the session management method of the embodiment of the present invention includes:

[0109] Step 31, during the service request process, receiving a session establishment failure message fed back when the network side fails to successfully establish a protocol data unit PDU session requested by the terminal, the session establishment failure message including session identification information;

[0110] It should be noted that the network side can be the core network side or the access network side; when the SMF entity on the core network side cannot establish a user plane connection for the PDU session, it will cause session establishment failure, or When the network access rejects the PDU session, the session establishment will also fail. In particular, it should be noted that, in order for the terminal to know which specific PDU sessions fail to be established, the session establishment failure message should include session identification...

Embodiment 2

[0149] Such as Image 6 As shown, the terminal 60 in the embodiment of the present invention includes:

[0150] The first receiving module 61 is configured to receive a session establishment failure message fed back when the network side fails to successfully establish a protocol data unit PDU session requested by the terminal during the service request process, and the session establishment failure message includes session identification information;

[0151] The processing module 62 is configured to deactivate the session corresponding to the session identification information.

[0152] It should be noted that the session establishment failure message is a non-access stratum NAS message.

[0153] Optionally, the first receiving module 61 is used for:

[0154] When the PDU session requested by the terminal is not successfully established on the network side, the session establishment failure message sent by the access and mobility management function AMF entity is received....

Embodiment 3

[0161] Such as Figure 7 As shown, the embodiment of the present invention provides a terminal, including:

[0162] Processor 71; and a memory 73 connected to the processor 71 through a bus interface 72, the memory 73 is used to store programs and data used by the processor 71 when performing operations, when the processor 71 calls and When executing the programs and data stored in the memory 73, the following processes are performed:

[0163] During the service request process, the session establishment failure message fed back when the network side fails to successfully establish the protocol data unit PDU session requested by the terminal is received by the transceiver 74, and the session establishment failure message includes session identification information;

[0164] Deactivate the session corresponding to the session identification information.

[0165] Wherein, the transceiver 74 is connected to the bus interface 72 and is used for receiving a session establishment ...

Abstract

The invention provides a session management method, a terminal, a management functional entity and an access network node, and relates to the technical field of communication. The session management method comprises the following steps: in a service request process, receiving a session establishment failure message fed back when a protocol data unit (PDU) session requested by the terminal is not established successfully on a network side, wherein the session establishment failure message includes session identification information; and performing deactivation of a session corresponding to thesession identification information. Through the scheme, the session establishment failure message is fed back to the terminal timely when the PDU session requested by the terminal is not established successfully on the network side, thereby solving the problem concerned with how to notify the terminal when a network refuses connection establishment of certain PDU sessions in a 5G service request process, ensuring synchronization of PDU sessions between the terminal and a core network side, and ensuring the reliability of network communication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a session management method, a terminal, a management function entity and an access network node. Background technique [0002] In the long term evolution (Long Term Evolution, LTE) system, the user equipment (User Equipment, UE, also referred to as terminal) initiates a service request process, if there is bearer information successfully established on the network side, through radio resource control (Radio Resource Control) , RRC) implicitly informs the UE of the bearer establishment process, and the RRC of the UE will inform the Non-Access Stratum (Non-Access Stratum, NAS) of the UE of the bearer information established by the air interface. For these bearers that are not established for the UE, the UE will Delete locally. However, in the 5G system, due to the separation of the control plane and the user plane, different protocol data unit (Protocol Data Unit, P...
