Embodiment 1

[0194] image 3 Showing the method of the present application SSC determining a mode according to an embodiment corresponding to such image 3 As shown, the method includes:

[0195] Step 301, the terminal apparatus determines that the requested mode of SSC.

[0196] Step 302, the terminal apparatus transmits a first core network element to the first request message, the first request message used to request establishing a first session PDU, in the first request message includes a session and a request for the first type of PDU session the SSC model.

[0197] Here, the first core network element NE may be a SMF, it is noted that, the terminal equipment may be, for example, AMF network element, sending a first request message to the first core network element through other devices, the present application is for the terminal or indirectly sending a first request message is not limited directly to the first core network element. The first request message may further comprise a first ...

Embodiment 2

[0217] Figure 4 SSC is a schematic flow chart to determine the application mode according to a second embodiment of a method corresponding to such Figure 4 As shown, the method includes:

[0218] Step 401, the terminal device transmits the capability information of the terminal device to the network element AMF.

[0219] Here, the terminal capability information of the terminal apparatus for indicating whether the device supports the Non-IP session SSC pattern 3, wherein, Non-IP session may include an Ethernet particular session and / or unstructured session.

[0220] Specifically, the terminal device may send a registration request message (registration request) to the network element AMF, the registration request message includes capability information may include the terminal device and the terminal device identification.

[0221] After step 402, AMF network element receives capability information of the terminal device sends a request message to the network element UDM (Nudm_...

[0262] Figure 5 Showing the method of the present application to determine SSC mode according to a third embodiment corresponding to such Figure 5 As shown, the method includes:

[0263] Step 501, the terminal device transmits terminal capability information of the device to the network element AMF.

[0264] Here, the terminal capability information of the terminal apparatus for indicating whether the device supports the Non-IP session SSC mode 3.

[0265] After step 502, AMF network element receives capability information of the terminal device sends a request message to the network element UDM, acquiring a terminal device for requesting subscription information.

[0266] Step 503, UDM NE sends a response message to the network element AMF.

[0267] Here, the response message may include a subscription information of the terminal device, and the subscription information associated with the session type for the terminal equipment session PDU allowed SSC pattern.

Abstract

The present application discloses a method and device for determining the SSC mode. The method includes: a terminal device determines the requested SSC mode, and sends a first request message to a first core network element, and the first request message is used to request establishment The first PDU session, the first request message includes the session type of the first PDU session, the requested SSC mode, and the first indication information; since the first request message sent by the terminal device to the first core network element It can carry the first indication information, which is used to indicate that the SSC mode requested by the terminal device is not allowed to be modified, so as to avoid wrong decisions made by subsequent network elements on the network side, such as modifying the requested SSC mode to other SSC modes not supported by the terminal device .

Description

Technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a method and apparatus for determining an SSC mode. Background technique [0002] Service and Session Continuity (SSC) Mode (MODE) is one of the properties of the Protocol Data Unit (PDU) session in the wireless communication system. The SSC mode usually has three values, respectively, SSC mode 1, SSC mode 2, SSC mode 3; wherein the session of SSC mode 1, PDU session anchor, PSA) does not change during session For the session of SSC mode 2, the PSA can be switched by first release the old session, and then create a new session; for the session of SSC mode 3, its PSA can create a new session first, and then delete the old session. The old session will have a total of a total of a total. [0003] In standard R15 (Release 15), for SSC mode 3 for Ethernet sessions and non-structural sessions 3, terminal devices cannot choose new session transfer or old session transmissi...
