It should be noted that, when the first condition is satisfied, the disaster condition of the network may or may not change. That is to say, in the embodiment of the present application, the terminal may execute the first operation as long as it obtains that the first condition is satisfied, regardless of whether the disaster condition of the network changes.
In the implementation of the present application, the terminal executes the first operation to improve the probability that the terminal can acquire a service, such as a Normal service (Normal service) or an emergency service, so as to improve the reliability of the terminal in acquiring the service. In particular implementations, the first operation may include, but is not limited to, at least one of:

Therefore, the probability of the terminal acquiring the service can be improved, and the reliability of the terminal acquiring the service can be improved.
The contents involved in the satisfaction of the first condition will be further described below.
1. For the first information in the aforementioned 1).
Optionally, the first information indicates at least one of:
i) a disaster condition applies to (applicable to) the first object;
ii) the object for which the disaster situation applies changes;
iii) the disaster situation does not apply to the second object;
iv) the third object can provide disaster roaming services;
v) the fourth object cannot provide disaster roaming service;
wherein the object comprises at least one of: a network; a tracking area; a cell; a geographic location.
In i), the first information indicates that the disaster condition is applicable to the object or objects, i.e. indicates that the disaster condition occurs in the object or objects and the service cannot be provided. The first object may comprise one or more (at least two) objects.
In ii), the first information indicates that the object to which the disaster condition applies has changed, i.e. that the extent to which the disaster condition has occurred has changed. In this case, further, the first indication information may also indicate an object to which the post-change disaster situation is applicable.
In iii) the first information indicates that the disaster situation does not apply to the object or objects. The first object may include one or more objects. Optionally, the second object may comprise at least one of: objects for which the disaster situation has been applicable; objects for which a disaster situation has not been applicable.
For an object for which the disaster condition was applicable, the first information may indicate that the disaster condition is no longer applicable to the object, i.e., the disaster condition stops or disappears at the object. In this case, further, the first information may also indicate a time when the disaster situation is no longer applicable to the object, i.e. a time when the disaster situation stops or disappears at the object.
For an object for which a disaster condition has not been applicable, the first information may indicate that the disaster condition has not been applicable to the object, i.e., that the disaster condition has not occurred at the object. Such as: assuming that the terminal location is unchanged, the terminal detects the object 1 after the signal strength of the object 1 is strengthened, and acquires that the disaster situation is not applicable to the object 1, then the terminal may perform a first operation to automatically change the network selected by the terminal to the object 1.
In iv), the first information indicates an object or objects that can provide disaster roaming service. The third object may include one or more objects. The third object may provide normal service and emergency service to the terminal in the object in which the disaster occurred.
In v), the first information indicates an object or objects that cannot provide the disaster roaming service. The fourth object may not provide a normal service to the terminal in the object in which the disaster occurred, but may provide an emergency service to the terminal in the object in which the disaster occurred. The fourth object may include one or more objects. Optionally, the fourth object comprises at least one of: objects that once were able to provide disaster roaming services; objects that fail to provide disaster roaming services.
For an object that once provided disaster roaming service, the first information may indicate that the object is no longer able to provide disaster roaming service, i.e., the object's ability to provide disaster roaming service disappears, deactivates, or stops.
For an object that is unable to provide disaster roaming services, the first information may indicate that the object is not capable of providing disaster roaming services, or that the object's ability to provide disaster roaming services is not activated or initiated. Such as: if the terminal detects the object b and the acquired object b cannot provide disaster roaming service, the selected object can be changed from the object a to the object b, so that compared with the case that the selected object a terminal cannot completely acquire service, the selected object b terminal can at least acquire emergency service, and the reliability of acquiring service by the terminal can be improved.
2. With respect to the aforementioned 2), that is, the first condition satisfies a condition including a change in the position of the terminal.

iv) said fifth object and said sixth object are both objects that are unable to provide disaster roaming services;
v) one of the fifth object and the sixth object is an object capable of providing disaster roaming service, and the other is not capable of providing disaster roaming service;
the fifth object is an object where the terminal is located before the position of the terminal is changed, namely, an object where the terminal is located before moving; the sixth object is an object where the terminal is located after the position of the terminal is changed, that is, the object where the terminal is located after moving; the object comprises at least one of: a network; a tracking area; a cell; a geographic location.
In i), the fifth object and the sixth object may both be objects for which a disaster situation applies or both may not apply.
In ii), one of the fifth object and the sixth object is an object for which a disaster is applicable, and the other object is an object for which a disaster is not applicable. Such as: the fifth object is an object suitable for disaster situations, and the sixth object is an object not suitable for disaster situations; or, the fifth object is an object for which the disaster condition is not applicable, and the sixth object is an object for which the disaster condition is applicable.
In v), it may be: the fifth object is an object capable of providing disaster roaming service, and the sixth object is an object incapable of providing disaster roaming service; or, the fifth object is an object which cannot provide the disaster roaming service, and the sixth object is an object which can provide the disaster roaming service.
The following explains contents related to the first operation.
1. For the first sub-operation.
Optionally, the first sub-operation comprises at least one of:
i) automatically leaving a first network selection mode where the terminal is currently located;
ii) automatically entering a second network selection mode;
iii) automatically changing the network selection mode of the terminal;
iv) determining the network selection mode after the terminal is changed;
v) determining a network selection mode before the terminal is changed;
vi) determining whether to change the network selection mode of the terminal;
in this alternative embodiment, in i), ii) and iii), the first sub-operation is an operation of directly changing a network selection mode of the terminal. In iv), v), and vi), the first sub-operation is an operation for determining whether to change a network mode of the terminal, where the terminal may or may not change the network selection mode, and may be determined according to actual requirements, which is not limited in this embodiment of the present application.
Further, the first network selection mode (i.e. the network selection mode before the terminal changes the network selection mode) and the second network selection mode (i.e. the network selection mode after the terminal changes the network selection mode) may satisfy at least one of the following:
(1) One of the first network selection mode and the second network selection mode is a manual network selection mode, and the other one is an automatic network selection mode; or both the first network selection mode and the second network selection mode are an automatic network selection mode or a manual network selection mode;
(2) One of the first network selection mode and the second network selection mode supports (may also be referred to as allowing or being able to) automatically selecting a non-equivalent network, and the other does not support automatically selecting a non-equivalent network;
(3) One of the first network selection mode and the second network selection mode supports a forbidden (forbidden) object for automatic selection, and the other does not support a forbidden object for automatic selection, the object including at least one of: a network; a tracking area; a cell; a geographic location.
In a specific implementation manner, in a first implementation manner, the first network selection mode and the second network selection mode may satisfy: (1) One of the first network selection mode and the second network selection mode is a manual network selection mode, and the other one is an automatic network selection mode. In this implementation, the first network selection mode and the second network selection mode may further satisfy at least one of (2) and (3). That is, in this implementation manner, the first network selection mode before the terminal changes the network selection mode and the second network selection mode after the terminal changes the network selection mode belong to different network selection mode types, and further, the capabilities of the first network selection mode and the second network selection mode, such as whether the capability of automatically selecting the non-equivalent network is supported and/or whether the capability of automatically selecting the prohibited object is supported, may be the same or different.
In a second implementation manner, the first network selection mode and the second network selection mode may satisfy: the first network selection mode and the second network selection mode in (1) are both an automatic network selection mode or a manual network selection mode, and at least one of (2) and (3). That is, in this implementation, the first network selection mode before the terminal changes the network selection mode and the second network selection mode after the terminal changes the network selection mode may be of the same type of network selection mode, but the capabilities of the first network selection mode and the second network selection mode, such as whether the capability of automatically selecting an unequivalent network is supported and/or whether the capability of automatically selecting a prohibited object is supported, are different.
For ease of understanding, the examples are illustrated below:
assume that the terminal automatically changes from network selection mode 1 to network selection mode 2.
Such as: for the first implementation manner, the network selection mode 2 may be a manual network selection mode when the network selection mode 1 is the automatic network selection mode; in the case where the network selection mode 1 is the manual network selection mode, the network selection mode 2 may be the automatic network selection mode. Further, the network selection mode 1 and the network selection mode 2 may both support automatic selection of the nonequivalent network and/or the prohibited object, or one of the network selection mode 1 and the network selection mode 2 supports automatic selection of the nonequivalent network and/or the prohibited object, and the other does not support automatic selection of the nonequivalent network and/or the prohibited object.
For the second implementation manner, the network selection mode 1 and the network selection mode 2 may both belong to an automatic network selection mode or an automatic network selection mode, and one of the network selection mode 1 and the network selection mode 2 supports automatic selection of a non-equivalent network and/or a prohibited object, and the other does not support automatic selection of a non-equivalent network and/or a prohibited object.
2. For the second sub-operation.
Optionally, the second sub-operation may include at least one of:
i) not selecting the first network;
ii) automatically selecting a second network;
iii) automatically changing the network selected by the terminal;
iv) determining the network selected by the terminal before changing;
v) determining the selected network after the terminal is changed;
vi) determining whether to change the selected network.
In i), the first network may be any one of: a network currently selected by the terminal; a network for which the disaster situation applies; networks that do not provide disaster roaming services.
When the first network is a network currently selected by the terminal, the specifically that the terminal does not select the first network may be: the terminal gives up selecting the first network, and the second sub-operation is an operation of directly changing the network selected by the terminal. In this case, the reason why the terminal does not select the first network may be: the disaster situation applies to the first network or the first network being unable to provide disaster roaming services, etc.
In ii), the second network may be any one of: networks for which disaster situations are inapplicable; a network capable of providing disaster roaming services. Further, the second network may satisfy at least one of:
the second network and the target network are not equivalent networks, and the target network is any one of the following networks: a home network of the terminal; the terminal selects a network before executing the first operation;
the second network is a forbidden network.
Further, the second network is a prohibited network, and may be specifically expressed as: the second network is a forbidden network corresponding to the target network.
Such as: assuming that the home network of the terminal is the network 1 and the network selected before the first operation is performed is the network 2, however, the network 2 has a disaster situation and cannot provide the service, the terminal may automatically select the network 3, and the network 3 may be a network for which the disaster is not applicable or a network capable of providing the disaster roaming service.
In one implementation, assuming that the target network is the home network of the terminal, the network 3 may not be an equivalent network of the network 1, i.e. the network 3 is a non-equivalent network of the network 1. Of course, the network 3 may also be an equivalent network of the network 1.
In another implementation, assuming that the target network is the network selected by the terminal before performing the first operation, the network 3 may not be an equivalent network of the network 2, that is, the network 3 is a non-equivalent network of the network 2. Of course, the network 3 may also be an equivalent network of the network 2.
In yet another implementation, the network 3 may be a prohibited network. Further, the network 3 may be a prohibited network corresponding to the network 1, or a prohibited network corresponding to the network 2.
In iii), the second sub-operation is an operation of directly changing a network selected by the terminal. The changed network may satisfy one of: disaster situations are not applicable; disaster roaming service can be provided.
In iv), v), and vi), the second sub-operation is an operation for determining whether to change the network selected by the terminal, where the terminal may change the selected network or may not change the selected network, and the second sub-operation may be determined according to actual requirements, which is not limited in this embodiment of the present application.
In the embodiment of the present application, optionally, the first operation may further include at least one of:
providing the first information to an upper layer of the terminal and/or a user;
providing location change information of the terminal to an upper layer (upper layer) of the terminal and/or a user (user);
providing operation information of the first sub-operation to an upper layer and/or a user of the terminal;
and providing the operation information of the second sub-operation to an upper layer and/or a user of the terminal.
In a specific implementation, the providing manner may include at least one of the following: display (display); notification (info or notify); forward or send; indication (indicator); the present disclosure may be determined according to actual situations, and is not limited in this application.
The location change information of the terminal may include at least one of: the relation between the object where the terminal is located before moving and the disaster situation, namely whether the disaster situation is suitable for the object where the terminal is located before moving; the relation between the object where the terminal is located after moving and the disaster condition; the relation between the object where the terminal is located before moving and the disaster roaming service, namely whether the object where the terminal is located before moving can provide the disaster roaming service or not; and the object where the terminal is located after moving is in relation with the disaster roaming service.
The operational information may include at least one of: an operation process; the operation result; the reason for the operation.
The network selection method according to the embodiment of the present application is described below with reference to specific scenarios.
1. Optionally, when the first information indicates that the disaster condition obtained by the terminal is applicable to a third network, if the terminal is in a manual network selection mode, the first operation may include at least one of the following:
automatically selecting a fourth network, the fourth network capable of providing disaster roaming services to the terminal;
and automatically leaving the manual network selection mode.
Further, the fourth network may not be an equivalent network of the third network. Of course, in some cases, the fourth network may be an equivalent network to the third network.
The third network may be a network selected before the terminal performs the first operation, that is, the third network is a network manually selected by the terminal through a manual network selection mode. Of course, in some cases, the third network may be the home network of the terminal.
It should be noted that, in the case that the first terminal includes the automatic selection fourth network, the terminal may still be maintained in the manual network selection mode, or may be changed to the automatic network selection mode.

Alternatively, the UE may automatically change the network selection mode when the UE knows that the DC is no longer applicable to network D.
Alternatively, when the UE knows that DC is no longer applicable to network D, the UE may automatically change the network selection mode: the manual mode is exited, for example, from the manual mode to the Automatic mode.
Alternatively, when the UE knows that DC is no longer applicable to network D, the UE may automatically change the network selection mode: leaving the Automatic mode, for example, changing from the Automatic mode to the manual mode.

Example 2: discovering the DC not applicable to network D, the UE automatically changes the network selection Mode from automatic Mode to manual Mode.
For ease of understanding, please refer to fig. 4. As shown in fig. 4, the network selection method may include the following steps:
step 0, the UE manually selects the network D, and the UE finds that the network D has DC.
And step 1, the UE leaves the manual network selection Mode, enters an automatic network selection Mode and automatically selects a network A.
The network a can provide disaster roaming service for the UE, and the PLMN a is in a list of forbidden networks (list of forbidden PLMNs) of the terminal.

In some embodiments, the UE may also automatically select an available network B, which is not network D. For example: since the PLMN a is in the list of forbidden PLMNs of the terminal, after the DC not applicable to the network D, the PLMN a may no longer provide services for the UE, so that the UE may not obtain normal services.
The UE may perform a signaling procedure with the network D, as in step 3a.
Step 3a, interacting with the network D signaling, such as a registration process;
in step 3b, the UE notifies the Upper layer (or user) that the UE has left the manual network selection mode.
