Description

technical field

The present application belongs to the technical field of communications, and in particular relates to a roaming processing method under disaster conditions, a terminal and a network side device.

Background technique

In the event of a disaster, such as a fire, mobile networks may not be able to provide service. To this end, it is stipulated in the related art that the 3GPP system should be able to enable a terminal of a given public land mobile network (PLMN) to obtain connection services (such as voice calls, mobile data services) from another PLMN for disaster conditions ( DisasterCondition, DC) applicable area. If disaster conditions apply and no other PLMNs are available except those in the forbidden PLMN (forbidden PLMN, FPLMN) list, the 3GPP system shall be able to provide a method to enable the terminal to access the PLMNs in the forbidden PLMN list. In non-disaster scenarios, terminals cannot access the FPLMN.

When the UE selects an FPLMN to access to obtain DC services, but in some scenarios, such as the update of the roaming agreement, the PLMN selected by the UE is no longer FPLMN, then the network will send "Not registered for disasterroaming service" (not registered disaster roaming service), so that the terminal cannot access the PLMN.

FIG. 2 is one of the schematic flowcharts of the method for handling roaming under disaster conditions provided by the embodiment of the present application. As shown in FIG. 2 , the method includes step 200 and step 201 .

Step 200, the terminal receives the first message sent by the first network.

Wherein, the information carried in the first message is used to indicate that the first network is a non-prohibited public land mobile network (PLMN) of the terminal.

Wherein, the first network is a network that provides disaster condition DC roaming services for the terminal.

It can be understood that if the first network that provides DC roaming service (disaster condition roaming service) for the terminal detects that the first network becomes a non-forbidden PLMN of the terminal, in other words, the first network is not in the forbidden PLMN list of the terminal, then , the first network may provide the terminal with a normal service instead of a DC roaming service. Then, the first network sends a first message to the terminal, where the first message carries information for indicating that the first network is a non-prohibited PLMN for the terminal.

Step 201, the terminal performs a first operation according to the first message.

After receiving the first message, the terminal learns that the first network is a non-prohibited PLMN of the terminal according to the first message, and then performs a first operation, and the first operation includes at least one of the following:

updating the forbidden PLMN list of the terminal;

A normal registration is performed at said first network.

It can be understood that after the terminal learns that the first network has become a non-prohibited PLMN, it can initiate a normal registration process to the first network, so that when the first network becomes a non-prohibited PLMN of the terminal, the first network can provide the terminal with a normal registration process. service, not DC service.

Optionally, before initiating a normal registration process, the terminal de-registers from the first network.

Optionally, after learning that the first network becomes a non-forbidden PLMN, the terminal may update the forbidden PLMN list of the terminal.

Optionally, the indicator indicator may also be a registration result, where the registration result is used to indicate that the first network is a non-prohibited PLMN of the terminal. For example, the terminal initiates DC registration with the first network, and the first network is the forbidden PLMN of the terminal, but in some cases, for example, the roaming policy between the first network and the home network of the terminal changes, and the first network becomes a The non-prohibited PLMN of the terminal. At this time, the registration result returned by the first network is "unregistered disaster roaming service" or "normal registration". According to the registration result, the terminal can know that the first network has become the non-prohibited PLMN of the terminal .

2) The first indication information is used to indicate 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 requirement indication information.

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 called a normal registration request message or a registration request message.

The terminal sends the second message to the first network, so that normal registration can be performed on the first network.

Optionally, when the first message is the configuration update command, parameter update command, or downlink NAS message, the de-registering from the first network includes at least one of the following:

a) deregistering from the first network within a specific time threshold;

The specific time threshold may be indicated by the first network, or preset.

Wherein, the information carried in the first message is used to indicate that the first network is a non-prohibited public land mobile network PLMN of the terminal, where the first network provides disaster condition DC roaming services for the terminal network.

It can be understood that if the first network detects that it has become a non-prohibited PLMN for the terminal, in other words, the first network is not in the terminal's forbidden PLMN list, at this time, the first network can provide normal services for the terminal instead of the DC Roaming service. Then, the first network sends a first message to the terminal, and the first message carries information indicating that the first network is a non-prohibited PLMN for the terminal, so that the terminal receives the first message, and according to the first message, Perform the first action.
