Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for processing terminal attachment, a terminal, and a network device.
Background
Attach with PDN Connectivity is a feature added in release 13 by 3GPP (3rd Generation Partnership Project), before which the terminal must synchronously establish a default PDN (Packet Data Network) connection while attaching to the 4G Network, and after adding this new feature, the terminal is allowed to Attach to the 4G Network but not establish the default PDN connection, that is, the terminal may be in an EMM-REGISTERED state without PDN connection, where the EMM is EPS Mobility Management, and the EPS is Evolved Packet System.
According to the 24.301 protocol, when both the terminal and the network support the Attach _ out PDN capability, if the terminal is configured as an EPS Attach _ out PDN Connection, and according to the 3GPP protocol 24.301, the terminal initiates an Attach Request on 4G, where an ESM message container (where the ESM is EPS Session Management), carries an ESM duplex message, the terminal does not initiate an Attach Request (Attach Request) when initiating the Attach Request (Attach Request), and in an Attach Request/TAU Request (Tracking Area Update Request) message, the terminal carries the Attach _ out PDN capability, but whether the network supports the Attach _ out PDN capability, and the terminal is obtained from an Attach _ TAU _ Accept message sent from the network. Once the information about the Attach without PDN capability of the opposite party acquired by the terminal or the network is inconsistent with the real situation, or the capability changes but the opposite party is not known in time, the terminal enters a scenario where the protocol is undefined, which may cause a network-hosting failure and affect the user service, for example:
1. when the Attach without PDN capability of the network is changed from support to non-support, the terminal cannot be informed actively, and the capability information of the network can be synchronized to the terminal only when the subsequent terminal initiates an Attach/TAU flow actively. Therefore, the terminal and the network information are not synchronized, which may cause subsequent flow abnormality and result in service failure.
If the PDN connection in the activated state is not available at present, the network enters an EMM-DEREGISTERED state, and a subsequent terminal cannot receive the called service; the terminal initiates the calling service and is rejected by the network, which results in service failure. If there is a PDN connection in an active state currently, because the terminal considers that the network still supports the Attach _ out PDN capability, deactivation of the last PDN connection may fail, and the terminal may not update the Attach _ out PDN capability of the network in time.
2. If the current terminal and the network both support the Attach out PDN capability and No activated PDN connection exists, if the terminal initiates TAU Request/Service Request to be rejected by the network, the terminal carries cause #40No EPS bearer context activated, and the terminal continues to consider that the network supports the Attach out PDN capability after receiving the Request, and the subsequent attachment process may fail.
3. The terminal initiates an Attach Request carrying an ESM (enterprise management protocol) message, if the network does not support the Attach without PDN (public data network) capability, an Attach Request #19 is issued, and the terminal may set an Attach attribute counter to 5 according to a 24.301 protocol, thereby disabling E-UTRAN, and causing the network to be unable to camp on the 4G network.
In summary, in the prior art, the access with out PDN capability of the network and the terminal is not synchronized, which results in a network-resident failure of the terminal and affects the user service.

One or more PDN connections may be established between the terminal and the network.
(1) The Attach with PDN capability of the network changes from supported to unsupported:
scene 1: as shown in fig. 5, if there is a PDN connection currently in an active state, the network needs not to notify the terminal for a while, and waits for the terminal to initiate an Attach Request/TAU Request for another reason, and then synchronizes the latest capability information to the terminal through the Attach Accept/TAU Accept.
Scene 2: as shown in fig. 5, if there is no PDN connection in the active state, the network actively notifies the terminal through IMSI paging or network detach Request (type: re-Attach), or in other manners, and after receiving the notification, the terminal considers that the current network no longer supports Attach without PDN capability, and initiates an Attach Request carrying a PDN Connectivity Request for re-registration.
Scene 3: as shown in fig. 5, if the terminal initiates deactivation of the Last bearer, the network replies PDN Disconnect Reject, which carries a specific cause, such as cause #49Last PDN disconnection not allowed, and after receiving the specific cause, the terminal considers that the current network no longer supports the Attach without PDN capability.
(2) The Attach with PDN capability of the network changes from unsupported to supported:
the scene does not need to be synchronized to the terminal immediately, the follow-up terminal initiates an Attach/TAU flow, and the network synchronizes the latest information to the terminal.

Scene 2: as shown in fig. 6, if there is no PDN connection currently in an active state, the terminal locates itself, and then sends an Attach Request message carrying a PDN Connectivity Request to the network, and the network updates the Attach with PDN capability of the terminal as unsupported.
(2) The Attach with out PDN capability of the terminal changes from unsupported to supported
The terminal actively initiates a TAU Request to indicate that the Attach without PDN capability is supported, and the scene belongs to the protocol flow specified in 24.301.
