Description
Technical Field

Background
In the event of a disaster (e.g., fire), the mobile network may not be able to provide service. For this purpose, the related art specifies that the 3GPP system should be able to enable a terminal of a given public land mobile network (public land mobile network, PLMN) to obtain connection services (e.g. voice calls, mobile data services) from another PLMN for areas where disaster conditions (Disaster Condition, DC) apply. If the disaster condition is applicable and no other PLMNs other than the Forbidden PLMN (FPLMN) list are available, the 3GPP system should be able to provide a method for enabling the terminal to access the PLMNs in the forbidden PLMN list. In a non-disaster scenario, the terminal cannot access the FPLMN.
When the UE selects one FPLMN access to obtain DC service, but because the PLMN selected by the UE is not already an FPLMN in some scenarios, such as updating of roaming agreements, the network may send "Not registered for disaster roaming service" (unregistered disaster roaming service), resulting in the terminal not having access to the PLMN.

Fig. 2 is a schematic flow chart of a disaster condition roaming processing method according to an embodiment of the present application. As shown in fig. 2, the method includes step 200 and step 201.
The information carried by the first message is used for indicating that the first network is a non-forbidden public land mobile network PLMN of the terminal.
Wherein the first network is a network providing disaster-condition DC roaming service for the terminal.
It will be appreciated that if the first network providing DC roaming service (disaster condition roaming service) to the terminal detects that the first network is a non-barred PLMN for the terminal, in other words, the first network is not in the barred PLMN list for the terminal, then the first network may provide normal service to the terminal instead of DC roaming service. Then the first network sends a first message to the terminal, the first message carrying information indicating that the first network is a non-barred PLMN for the terminal.
After receiving the first message, the terminal acquires that the first network is a non-forbidden PLMN of the terminal according to the first message, and then executes a first operation, wherein the first operation comprises at least one of the following:
updating a forbidden PLMN list of the terminal;
deregistering from the first network;
normal registration is performed at the first network.
It will be appreciated that after knowing that the first network becomes a non-forbidden PLMN, the terminal may initiate a normal registration procedure with the first network, so that in the case that the first network becomes a non-forbidden PLMN for the terminal, the first network can provide normal services for the terminal, instead of DC services.
Optionally, before initiating the normal registration procedure, the terminal de-registers from the first network.
Optionally, after the terminal knows that the first network becomes a non-forbidden PLMN, the forbidden PLMN list of the terminal may be updated.
Optionally, the updating the forbidden PLMN list of the terminal includes:
and deleting the first network from the forbidden PLMN list of the terminal.
Note that, in the embodiment of the present application, normal registration includes: initial registration, mobility registration update or periodic registration update.
In the embodiment of the application, under the condition that the terminal knows that the first network becomes a non-forbidden PLMN, the first operation is executed, so that the first network can provide normal service for the terminal, thereby avoiding service interruption and meeting the service requirement of the terminal.
In some embodiments, the information carried by the first message includes at least one of: first information; first indication information; and second indication information.
1) First information for indicating that the first network is a non-forbidden PLMN of the terminal;
in other words, the first network is not in the forbidden PLMN list of the terminal.
Optionally, the first information includes at least one of: an indicator for indicating that the first network is a non-forbidden PLMN of the terminal; and PLMN identification of the first network.
Alternatively, the indicator may be a new parameter or a registration result.
The new parameter means that the indicator is a newly defined parameter, and the parameter is used to indicate that the first network is a non-forbidden PLMN of the terminal.
Alternatively, the indicator may be a registration result, where the registration result is used to indicate that the first network is a non-forbidden PLMN of the terminal. For example, the terminal initiates a DC registration with the first network, where the first network is a forbidden PLMN of the terminal, but in some cases, for example, where a roaming policy between the first network and a home network of the terminal changes, the first network becomes a non-forbidden PLMN of the terminal, where a registration result returned by the first network is "unregistered disaster roaming service" or "normal registration", and according to the registration result, the terminal can learn that the first network becomes a non-forbidden PLMN of the terminal.
2) The first indication information is used for indicating re-registration requirement information;
wherein, the re-registration requirement information refers to "re-registration required".
The first indication information may also be referred to as re-registration need indication information.
3) The second indication information is used for indicating the terminal to update the context and changing the registration type into normal registration.
The second indication information may also be referred to as normal registration indication information.
In some embodiments, the first message includes at least one of:
a deregistration request message for instructing a terminal to deregister from the first network;
configuring an update command;
a parameter update command;
downlink non-access stratum NAS messages.
In one embodiment, the first message is a deregistration request message, and the information carried by the deregistration request message includes at least one of the following: first information; first indication information; and second indication information.
For example, the terminal receives a deregistration request message sent by the first network, where the deregistration request message carries re-registration requirement information and normal registration indication information. And the terminal deletes the first network from the forbidden PLMN list of the terminal according to the deregistration request message, deregisters from the first network, and executes normal registration on the first network.
In one embodiment, the first message is a configuration update command, and the information carried by the configuration update command includes at least one of the following: first information; first indication information; and second indication information.
For example, the terminal receives a configuration update command sent by the first network, where the configuration update command carries normal registration indication information. And the terminal deletes the first network from the forbidden PLMN list of the terminal according to the configuration updating command, de-registers the first network, and executes normal registration on the first network.
In one embodiment, the first message is a parameter update command, and the information carried by the parameter update command includes at least one of the following: first information; first indication information; and second indication information.
For example, the terminal receives a parameter update command sent by the first network, where the parameter update command carries normal registration indication information. And the terminal deletes the first network from the forbidden PLMN list of the terminal according to the parameter updating command, de-registers the first network, and executes normal registration on the first network.
In one embodiment, the first message is a downlink non-access stratum (NAS) message, where information carried by the downlink NAS message includes at least one of the following: first information; first indication information; and second indication information.
For example, the terminal receives a downlink NAS message sent by the first network, where the downlink NAS message carries normal registration indication information. And the terminal deletes the first network from the forbidden PLMN list of the terminal according to the downlink NAS message, de-registers the first network, and executes normal registration in the first network.
The first information, the first indication information, and the second indication information are described in the foregoing embodiments, and are not described herein.
Optionally, the performing normal registration in the first network includes:
and sending a second message to the first network, wherein the second message is used for requesting normal registration to the first network.
In some embodiments, the second message may be an initial registration request message, or a mobility and periodic registration update request message.
The second message may also be referred to as a normal registration request message or a registration request message.
The terminal transmits the second message to the first network so that normal registration can be performed in the first network.
Optionally, in the case that the first message is the configuration update command, the parameter update command, or the downlink NAS message, the deregistering from the first network includes at least one of:
a) Deregistering from the first network within a certain time threshold;
the specific time threshold may be indicated by the first network or preset.
In one embodiment, the terminal may immediately perform a de-registration procedure when the specific time threshold is 0, or a value near zero.
b) Registering from the first network in case the terminal enters an idle state;
c) Registering from the first network in case the first service of the terminal ends;
wherein the first service includes at least one of: a multimedia telephony (Multimedia telephone, MMTEL) voice call; MMTEL video call; a short message service (SMS over NAS, SMSoNAS) transmitted through the NAS layer or a short message service (SMS over IP, SMSoIP) transmitted through the IP layer.
It can be understood that the first service is a high-priority task of the terminal, and after the high-priority task of the terminal is finished, the deregistration process is executed, so that the terminal can execute the deregistration process under the condition of meeting the service requirement.
After the deregistration process is performed, the terminal performs a normal registration process.
Optionally, the first message is delivered through at least one of the following procedures: UE configuration update (UE configuration update, UCU) procedure, UE parameter update (UE parameter update, UPU) procedure, roaming bootstrap (steering of roaming, soR) procedure.
It is understood that in the case where the first message is a configuration update command, the first message is delivered in the UCU flow.
In the case that the first message is a parameter update command, the first message is passed in the UPU flow.
And when the first message is a downlink non-access stratum (NAS) message, the first message is transmitted in a SoR flow.
In the embodiment of the application, the terminal receives the first message, knows that the first network becomes a non-forbidden PLMN, and executes the first operation, so that the first network can provide normal service for the terminal, thereby avoiding service interruption and meeting the service requirement of the terminal.
FIG. 3 is a second flowchart of a disaster-condition roaming processing method according to an embodiment of the present application. As shown in fig. 3, the method includes step 300.
The information carried by the first message is used for indicating that the first network is a non-forbidden public land mobile network PLMN of the terminal, wherein the first network is a network for providing disaster condition DC roaming service for the terminal.
It will be appreciated that if the first network detects that it is a non-barred PLMN for the terminal, in other words, the first network is not in the barred PLMN list for the terminal, then the first network may provide normal services for the terminal instead of DC roaming services. And then, the first network sends a first message to the terminal, wherein the first message carries information for indicating that the first network is a non-forbidden PLMN of the terminal, so that the terminal receives the first message, and executes a first operation according to the first message.
It should be noted that the first network may be a network side device, for example, may be an access network device or a core network device, and the embodiment is not limited specifically.
Wherein the first operation comprises at least one of: updating a forbidden PLMN list of the terminal; deregistering from the first network; normal registration is performed at the first network.
In some embodiments, the information carried by the first message includes at least one of: first information; first indication information; and second indication information.
1) First information for indicating that the first network is a non-forbidden PLMN of the terminal;
in other words, the first network is not in the forbidden PLMN list of the terminal.
Optionally, the first information includes at least one of: an indicator for indicating that the first network is a non-forbidden PLMN of the terminal; and PLMN identification of the first network.
Alternatively, the indicator may be a new parameter or a registration result.
The new parameter means that the indicator is a newly defined parameter, and the parameter is used to indicate that the first network is a non-forbidden PLMN of the terminal.
Alternatively, the indicator may be a registration result, where the registration result is used to indicate that the first network is a non-forbidden PLMN of the terminal. For example, the terminal initiates a DC registration with the first network, where the first network is a forbidden PLMN of the terminal, but in some cases, for example, where a roaming policy between the first network and a home network of the terminal changes, the first network becomes a non-forbidden PLMN of the terminal, where a registration result returned by the first network is "unregistered disaster roaming service" or "normal registration", and according to the registration result, the terminal can learn that the first network becomes a non-forbidden PLMN of the terminal.
2) The first indication information is used for indicating re-registration requirement information;
wherein, the re-registration requirement information refers to "re-registration required".
The first indication information may also be referred to as re-registration need indication information.

wherein the first condition includes at least one of:
a roaming policy between the first network and a home network of the terminal changes;
the first network detects that the first network is not in the forbidden PLMN list for the terminal.
It will be appreciated that in the first network detecting that the first network is not in the forbidden PLMN list for the terminal, the first network sends a first message to the terminal.
