Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The updating method, the reconstruction request processing method, the terminal and the network equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (LTE) system, a subsequent Evolution communication system, or the like.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a User Equipment (UE) or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited. The network device 12 may be a 4G base station, or a 5G base station, or a later-version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), or an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station and the 4G base station are taken as examples, but the specific type of the network device is not limited.

Referring to fig. 2a, fig. 2a is a flowchart of an updating method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2a, the method includes the following steps:

step 201, initiating an updating process under the condition that the cell reselected by the terminal belongs to ePLMN and belongs to the current registration area of the terminal.

The reselected cell may be a cell for which the terminal performs RRC reestablishment (RRC reestablishment) reselection.

The ePLMN may be an ePLMN of a PLMN currently registered by the terminal, for example: and the terminal reselects the ePLMN of the PLMN to which the serving cell before the cell belongs.

The current registration area may be a registration area allocated to the terminal by the PLMN currently registered by the terminal, and the registration area may include a plurality of Tracking Areas (TAs).

Wherein, in the updating process, the network side may be informed that the PLMN to be registered by the terminal is the ePLMN, for example: when forwarding an Update message sent by a terminal to a core network by a base station in an Update process, the Update message carries an identifier of the ePLMN, wherein the Update message is a registration request message in a mobility and periodic registration Update process of 5G, and the Update message is a TAU request message in a Tracking Area Update (TAU) process of 4G.

The initiating update process may be an update process initiated to a network side to inform the network side that a terminal selects the epdmn through the process, so as to implement PLMN matching between the terminal and the network, that is, PLMNs registered by the terminal in the context of the terminal and the network are synchronous, so that the terminal and the network use the same PLMN ID in a subsequent authentication process, and thus the authentication is successful.

In this embodiment of the present invention, the update process may be an update process that can notify the network side terminal to select the ePLMN, for example: a location update procedure. Further, the Update procedure may be a registration Update (registration Update) procedure, or a Tracking Area Update (TAU) procedure, where the registration Update procedure may be a mobility and periodic registration Update procedure in a 5G system, or a registration Update procedure in a subsequent evolved communication system, and the TAU procedure may be a TAU procedure in a 4G system.

As an optional implementation, the cell is:

a non-shared network cell or a shared network cell.

The non-shared network cell may be a core network node to which a base station to which the cell belongs is connected to only one PLMN, and the shared network cell may be a core network node to which a base station to which the cell belongs is connected to two or more PLMNs. In the 5G system, the core network node may be an Access Mobility management function (AMF), and in the 4G system, the core node may be a Mobility Management Entity (MME).

In addition, in this embodiment of the present invention, the cell reselected by the terminal may refer to that the terminal reselects the cell in a connected state. Taking a 5G network as an example, the cell may be a cell reselected by the terminal in a 5G Mobility Management (5G Mobility Management5GMM) connection state, that is, a cell reselected by the terminal in a 5GMM-CONNECTED mode. Taking a 4G network as an example, the cell may be a cell reselected by the terminal in an EPS Mobility Management (EMM) connection state, that is, a cell reselected by the terminal in an EMM-CONNECTED mode.

Therefore, when the cell is the non-shared network cell, the terminal initiates an update process when reselecting to the non-shared network cell belonging to the ePLMN and the current registration area in the connected state.

Further, in a case that the cell is the shared network cell, the initiating an update procedure includes:

and entering an idle state and initiating an updating process.

Thus, it can be realized that, in the case that the cell is a shared network cell, the terminal enters an idle state and initiates an update process, for example: and when the terminal reselects the unshared network cell which belongs to the ePLMN and belongs to the current registration area in the connection state, the terminal enters an idle state and initiates an updating process.

Wherein, the entering into the idle state may include:

a Non-access stratum (NAS) receives a fallback indication (fallback indication) of an Access Stratum (AS) and enters an idle state.

For example: the updating method as shown in fig. 2b comprises the following steps:

2011. when the cell reselected by the terminal belongs to ePLMN and belongs to the current registration area of the terminal, the NAS receives a backspacing instruction of an AS and enters an idle state;

2012. an update process is initiated.

The backoff instruction may be a backoff instruction sent by the AS of the terminal to the NAS after the AS of the terminal receives an RRC setup message sent by the network side, and the NAS receives the backoff instruction, and then the terminal enters an idle state.

In this embodiment, when the terminal reselects the shared network cell belonging to the ePLMN and the current registration area in the connected state, the NAS of the terminal receives the fallback indication of the AS, enters the idle state, and initiates the update process. Therefore, the synchronization of the terminal and the PLMN selected by the network can be realized by the least change of the NAS and the AS of the terminal, and the condition that the terminal and the PLMN registered by the network are out of synchronization is avoided.

In one implementation, before the NAS receives a fallback indication of an AS and enters an idle state, the method may further include:

transmitting an RRC Reestablishment Request (RRC Request) message;

receiving an RRC Setup (RRC Setup) message;

wherein the updating process comprises: and sending an RRC Connection setup complete (RRC Connection setup complete) message, wherein the RRC Connection setup complete message carries an update message and the ePLMN identifier.

Wherein, the update message is a registration request message in the mobility and periodic registration update process of 5G, and the update message is a TAU request message in the TAU process of 4G.

Specifically, as shown in fig. 3, the network in fig. 3 may represent a network device that performs message interaction with the terminal, for example: and a base station.

The RRC setup message may be understood AS a response of the network to the RRC reestablishment request, that is, the terminal sends the RRC reestablishment request, but since the current network belongs to the shared network, the network cannot determine that the terminal selects a PLMN to be registered, and therefore the network does not perform RRC reestablishment, but responds to the RRC reestablishment request through the RRC setup message, so that the AS of the terminal sends the fallback indication to the NAS to enter an idle state. The RRC connection setup complete message may be understood as that the terminal sends the update message to the network through the RRC message, where the update message includes the ePLMNID of the terminal reselection. It should be noted that, in the embodiment of the present invention, it is not limited to send the ePLMN ID through the RRC connection setup complete message, and the ePLMN ID may also be sent to the network through another message in the update process.

Therefore, when the cell reselected by the terminal is the shared cell, the RRC establishment message is fed back to the terminal through the network to serve as the response of the RRC reestablishment request, the terminal is triggered to enter an idle state, and the updating process is initiated.

Taking 5G as an example, when a terminal in 5G mobility management connection mode enters a shared network cell, the cell is located in the current registration area, and the cell belongs to the equivalent PLMN of the current registered PLMN but not to the current registered PLMN (when the ue is in 5GMM-CONNECTED mode entries a shared network cell in the current registration area associating area assigning to an equivalent PLMN of the registered PLMN), the network device responds to the RRC reestablishment request through the RRC Setup message, i.e. the network device behavior may be that the base station responds with an RRC Setup (the nb locations with an RRC Setup). For example: when the RRC connection is reestablished and the network cannot retrieve or verify the context of the terminal (When the UE is idle-idle an RRC connection and the network is not able to retrieve the UE context), since the network device (e.g., the base station) belongs to the shared network and cannot determine to which core network node of the network the message of the terminal is forwarded, the network device (e.g., the base station) selects to trigger the terminal to go back to establish a new RRC connection (fallback-idle a new RRC connection).

In the foregoing embodiment, after entering the idle state, the NAS of the terminal initiates an update process, and notifies the terminal of the selected AS PLMN ID, that is, the identifier of the ePLMN, and carries the selected AS PLMN ID in an RRC Connection setup complete (RRC Connection setup complete) message, so that the network side can be notified in the shared cell that the terminal selects a new PLMN, and the terminal and the PLMN selected by the network are matched.

As an optional implementation manner, the update procedure is a mobility and periodic registration update procedure, or the update procedure is a TAU procedure.

The mobility and periodic registration update procedure may be a registration update procedure in a 5G system, or a mobility and periodic registration update procedure in a subsequent evolved communication system, and the TAU procedure may be a TAU procedure in a 4G system.

It should be noted that, in the case that the cell is a shared network cell or an unshared network cell, the update procedure may be a mobility and periodic registration update procedure or a TAU procedure.

In addition, in this embodiment, the REGISTRATION REQUEST message (REGISTRATION REQUEST) in the mobility and periodic REGISTRATION update procedure is used to indicate: and the user plane resource of the terminal is in an activated Protocol Data Unit (PDU) session.

The indication of the PDU session by the registration request message may be that the PDU session is indicated by an Uplink data status IE in the registration request message, so as to reduce the change to the registration request message. Of course, this is not limited, for example: an indication field may be added to the registration request message to indicate the PDU session.

Wherein, the PDU session may include: before the terminal enters an IDLE state (IDLE state), the user plane resources are in the PDU session of the active state. Therefore, the PDU conversation that all the user plane resources are in the active state before entering the idle state can be indicated to the network side.

Due to the PDU session indicating that the user plane resources are in the activated state, the transmission of the PDU session can be quickly recovered between the terminal and the network side, so that the transmission efficiency of the PDU session is improved.

Taking 5G as an example, when a non-shared cell of a terminal in 5G mobility management connection mode entering a current registration area belongs to an equivalent PLMN of a currently registered PLMN but does not belong to the currently registered PLMN (when the UE in 5GMM-connected modes entries a cell in the current registration area is having a routing area to an equivalent PLMN of the registered PLMN), the terminal initiates a mobility and periodic registration update procedure, and an Uplink data IE in the registration request message indicates that the user plane resources are in an active PDU session before entering an IDLE state.

Taking 5G as an example, when a terminal in 5G mobility management connected mode accessed through 3GPP receives a fallback indication from an access stratum, if the terminal enters a shared network cell, the cell is in a current registration area and the cell belongs to an equivalent PLMN of the current registration PLMN, but not the current registered PLMN (When the UE is in 5GMM-CONNECTED mode 3GPP access users a failure indication from low levels, and if the UE entries a shared network cell in the current registration area associating PLMN of the registered PLMN and not associating to the registered PLMN), the terminal enters 5G mobile management IDLE mode (entry 5GMM-IDLE mode), and initiating mobility and periodic registration update procedures, and indicating the PDU session with the user plane resources in an active state before entering an IDLE state by an Uplink data status IE in the registration request message.
