The following describes in detail a network access triggering scheme provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 2 shows a flowchart of a method for triggering network access in an embodiment of the present application, where the method 200 may be performed by a first network. In other words, the method may be performed by software or hardware installed on a network side device (e.g., a base station) of the first network. As shown in fig. 2, the method may include the following steps.
S210, in the process that the target terminal receives the service from the first network, the target terminal is determined to need to be accessed to a second network.
In the embodiment of the application, when the target terminal is normally served by the first network, and the first network finds that the second network is available, the target terminal is determined to need to access the second network.
In one possible implementation, the determining, by the first network, that the target terminal needs to access the second network may include: the first network is found to begin to disaster and the second network can provide services normally. For example, when the UE is in the connected state, the first network finds that the first network is beginning to suffer a disaster, and may not be able to provide normal services, while the second network is able to provide normal services. For example, some network elements of the first network may have a disaster, but other network elements are still available, and the available network elements may send a disaster notification to the UE.
In another possible implementation manner, the determining, by the first network, that the target terminal needs to access the second network may include: and determining that the second network is recovered to be normal, wherein the target terminal receives service from the second network before the second network is in disaster, and accesses the first network after the second network is in disaster. For example, when the UE is in a connected state in the second network, the second network has a disaster, the UE attempts and accesses the first network, and after the second network recovers to normal, the first network determines that the second network recovers, and all UEs in the second network that were previously in the disaster state should perform network reselection, that is, all UEs in the second network that were previously in the disaster state need to access the second network.
S212, starting a first timer corresponding to the target terminal, wherein the time lengths of the first timers corresponding to a plurality of different terminals are not completely the same.
In this embodiment, each of the terminals corresponds to a first timer, and the durations of the first timers corresponding to some terminals in the durations of the first timers are different, or the durations of the first timers corresponding to all terminals in the durations of the first timers are different from each other.
S214, triggering the target terminal to attempt to access the second network when the first timer is over time.
In the embodiment of the application, in the process that a target terminal receives a service from a first network, if the first network determines that the target terminal needs to access a second network, a first network device starts a first timer, wherein for a plurality of different target terminals, the durations of the first timer are not completely the same; and then triggering the target terminal to try to access the second network when the first timer is timed out. Therefore, the problem that a large number of target terminals simultaneously try to access the second network to cause congestion of the second network can be avoided.
In one possible implementation, the duration of the first timer may be determined according to a random value within a predetermined range. That is, in this possible implementation, before starting the first timer, the method further includes: and taking a random value in a preset range, and determining the time length of the first timer corresponding to the target terminal according to the random value. For example, the duration of the first timer may be a random value within a predetermined range, or a duration calculated according to the random value. By this possible implementation, it can be ensured that the target terminal randomly accesses the second network within a predetermined range, rather than simultaneously accessing the second network.
In a possible implementation manner, the first network may also determine the duration of the first timer according to the target parameter information. That is, in this possible implementation, before starting the first timer, the method further includes: and determining the duration of the first timer according to the target parameter information.
In the foregoing possible implementation manner, optionally, the target parameter information may include at least one of:
(1) identification information of the target terminal; for example, the duration of the first timer corresponding to the target terminal may be calculated according to the identification information of the target terminal.
(2) Identification information of the first network. For example, the ID of the first network.
(3) And the subscription information of the target terminal. For example, subscription information of the target terminal, such as priority, etc., may be used as the calculation reference information.
Optionally, the subscription information of the target terminal may include a priority of the target terminal, and when determining the duration of the first timer, the duration of the first timer corresponding to the terminal with the higher priority is shorter. For example, in the event of a disaster in the first network, a UE with a lower priority may be given a timer that is calculated to be longer to allow the UE to access the second network later and to provide normal service to the UE later.
(4) Identification information of the second network. For example, the ID of the second network.
In the foregoing possible implementation manner, optionally, when determining the duration of the first timer according to the target parameter information, the principle of determining the duration of the first timer may include: if the second network and the first network are equivalent networks, the duration of the first timer corresponding to the first terminal is less than the duration of the first timer corresponding to the second terminal, wherein the first network is a home network of the first terminal, and the first network is not the home network of the second terminal. For example, when a disaster occurs in the first network, it may be guaranteed that the home terminal of the first network is preferentially changed to the second network, and therefore, for the target terminal belonging to the first network, the duration of the corresponding first timer is less than that of the target terminal not belonging to the first network.
In practical application, whether the first network and the second network are equivalent networks and whether the target terminal is a home terminal of the first network may be determined according to the identifier of the first network, the identifier of the second network and the subscription information of the target terminal.
In the foregoing possible implementation manner, optionally, when determining the duration of the first timer according to the target parameter information, the principle of determining the duration of the first timer may include: the duration of the first timer corresponding to a first terminal is less than the duration of the first timer corresponding to a second terminal, where the second network is a forbidden (forbidden) network of the second terminal, and the second network is a non-forbidden network of the first terminal. The second network is a prohibited network of the second terminal, which means that when the second terminal attempts to access the second network, the second network rejects the access of the second terminal for reasons such as "PLMN nothing allowed" and the like. For example, the second network does not have a subscription with the first network for normal service, and if the UE attempts to access the second network in the absence of a disaster, the UE will be rejected by the reason "PLMN not allowed", that is, the second network is a forbidden network of the UE. In this possible implementation, since the second network is a prohibited network of the second terminal, an earlier attempt by the second terminal to access the second network may also be rejected, and thus may leave the first network later and enter the second network later.
In practical application, whether the second network is a forbidden network of the target terminal may be determined according to the identifier of the second network and the subscription information of the target terminal, so that the duration of the first timer corresponding to the target terminal may be determined.
In the foregoing possible implementation manner, optionally, when determining the duration of the first timer according to the target parameter information, the principle of determining the duration of the first timer may include: if the second network and the first network are equivalent networks, the duration of the first timer corresponding to the first terminal is greater than the duration of the second timer corresponding to the second terminal, wherein the second network is a home network of the first terminal, and the second network is not the home network of the second terminal. For example, for a UE belonging to the second network, when the second network is in a disaster, the UE changes to an equivalent network of the second network (i.e., the first network), and when the second network recovers, because the first network is the equivalent network of the second network, the first network may provide normal service for the UE, and the UE may leave the first network later, so that the duration of the first timer corresponding to the UE may be longer. Therefore, in this possible implementation manner, for the target terminal belonging to the second network, the duration of the corresponding first timer is greater than that of the target terminal not belonging to the second network.
In the foregoing possible implementation manner, optionally, when determining the duration of the first timer according to the target parameter information, the principle of determining the duration of the first timer may include: the duration of the first timer corresponding to a first terminal is greater than the duration of the first timer corresponding to a second terminal, wherein the first network is a forbidden network of the second terminal, and the first network is a non-forbidden network of the first terminal. In this possible implementation, since the first network is a forbidden network of the second terminal, such UEs require to leave the first network as soon as possible, and the duration of the first timer corresponding to such UEs is small. For example, the second network does not subscribe to the first network for normal service, and if the UE attempts to access the first network and is to be rejected by the cause "PLMN nothing allowed" in the absence of a disaster, it is required for such UE to leave the first network as soon as possible so that the first network stops serving it. If the second network is the home network of the UE, the UE is returned to its home network as soon as possible, so that the forbidden network (i.e. the first network) of the UE stops serving the UE as soon as possible.
Fig. 3 shows another flowchart of a method for triggering network access in the embodiment of the present application, where the method 300 may be performed by a terminal, a target network, and an original network. In other words, the method may be performed by software or hardware installed on the terminal, the network-side device of the target network, and the network-side device of the original network. As shown in fig. 3, the method may include the following steps.
S301. the UE currently receives service in the original network.
S302, the original network finds that the target network is available.
The method 200 may be used for discovering that the target network is the same as that for determining that the target terminal needs to access the second network by the first network, which may specifically refer to the related description in the method 200 and is not described herein again.
S303, the original network starts a target timer corresponding to the UE.
Wherein, the durations of the target timers corresponding to different UEs are not completely the same. The original network may determine the duration of the target timer in a manner that the first network determines the duration of the first timer corresponding to the target terminal in the method 200, which is specifically referred to the related description in the method 200 and is not described herein again.
S304, the target timer is overtime.
S305. the original network informs the UE that the target network is available, which may inform the terminal through signaling, such as a release message, or a registration reject message.
And S306, after receiving the information which is sent by the original network and is available by the target network, the UE tries to access the target network.
In the embodiment of the application, in the process that the UE receives the service from the original network, if the original network finds that the target network is available, the original network equipment starts a target timer corresponding to the UE; then, when a target timer expires, the UE is triggered to attempt to access the target network. Therefore, the problem that a large number of UEs attempt to access the target network at the same time to cause the congestion of the target network can be avoided.
Fig. 4 shows a further flowchart of a method for triggering network access in the embodiment of the present application, where the method 400 may be performed by a terminal, a first network, and a second network. In other words, the method may be performed by software or hardware installed on the terminal, the network-side device of the first network, and the network-side device of the second network. As shown in fig. 4, the method may include the following steps.
And S401, the UE normally serves in the first network.
S402, the first network is in disaster, and the second network is in normal service.
And S403, the first network starts a first timer corresponding to the UE.
For example, a part of network elements of the first network are in a disaster, but a part of the network elements are still available, and the available network elements may send a disaster notification to the UE, where the UE may be currently in, but is not limited to, a connected state.
The durations of the first timers corresponding to different UEs are not completely the same. The first network may determine the duration of the first timer in a manner that the first network determines the duration of the first timer corresponding to the target terminal in the method 200.
For example, the first network may take a random value for a different UE. Alternatively, the first network may use information of the UE (e.g., UE ID), information of the second network (i.e., target network) (e.g., second network ID), subscription information of the UE (e.g., priority), and the like as the calculation reference information.
The principle that the first network determines the duration of the first timer may include at least one of the following:
(1) a UE with a lower priority may be given a timer that is calculated to be longer to require the UE to access the second network later and to provide normal service to the UE later.
(2) The second network is Equivalent to the first network, for example, the UE belongs to the first network, and the second network is a peer-to-peer Home network (ehplmn) of the Home network of the UE, and for the UE belonging to the first network, it is required to leave the first network and enter the second network as soon as possible to obtain normal service as soon as possible, and therefore, the first timer corresponding to the UE belonging to the first network is shorter than the first timer corresponding to the UE not belonging to the first network.
(3) If the second network is a forbidden network of the UE, for example, the second network does not have a subscription with a home network (i.e., the first network) for normal service, when a disaster does not occur, if the UE attempts to access the second network and is to be rejected by the reason "PLMN not allowed", the duration of the first timer corresponding to the UE of the second network as a forbidden network is longer than the duration of the first timer corresponding to the UE of the second network as a non-forbidden network, that is, the UE of the second network as a forbidden network may leave the first network later and enter the second network.
S404, the first timer is overtime.
S405, the first network informs the UE that the first network has a disaster, and the terminal is triggered to try to access the second network;
s406. after receiving the notification message in S405, the ue attempts access at the second network.
Fig. 5 shows a further flowchart of a method 500 for triggering network access in the embodiment of the present application, where the method may be performed by a terminal, a first network, and a second network. In other words, the method may be performed by software or hardware installed on the terminal, the network-side device of the first network, and the network-side device of the second network. As shown in fig. 5, the method may include the following steps.
S501. the ue receives normal service in the second network.
In the embodiment of the present application, before S501, when the UE receives normal service in the first network, the first network has a disaster, and the UE accesses the second network.
In a specific application, the UE may access the second network by using the method described in the method 400, which is not limited to this, and the UE may also access the second network by using other methods, which is not limited in this embodiment of the present application.
S502, the first network recovers to be normal.
S503, after the second network finds that the first network which originally has the disaster recovers to be normal, the second network starts a second timer corresponding to the UE.
And the duration of the second timers corresponding to different UEs is not completely the same. The first network may determine the duration of the second timer in a manner that the first network determines the duration of the first timer corresponding to the target terminal in the method 200.
For example, the second network may take a random value for a different UE. Alternatively, the second network may use information of the UE (e.g., UE ID), information of the second network (i.e., target network) (e.g., second network ID), subscription information of the UE (e.g., priority), and the like as the calculation reference information.
Wherein the principle that the second network determines the duration of the second timer may include at least one of:
(1) the UE with lower priority may be given a longer timer to request the UE to access the first network later.
(2) If the first network is an equivalent network to the second network, for example, the second network is a home network of the UE, and the first network is an EHPLMN network of the home network of the UE, the UE belonging to the first network (for example, the first network is an HPLMN of the UE) may leave the second network later, so that the duration of the second timer corresponding to the UE belonging to the first network is longer than the duration of the second timer corresponding to the UE not belonging to the first network.
(3) The second network is the forbidden network of the UE, for example, the second network does not sign normal service with the first network, that is, if the UE is trying to access the second network and is rejected by the reason "PLMN not allowed" in case of no disaster, for such UE, for example, the first network is the HPLMN of the UE, it is required to leave the second network as soon as possible to return the UE to its home network as soon as possible so that the second network stops serving it. Therefore, the duration of the second timer corresponding to the UE in which the second network is the prohibited network is less than the duration of the second timer corresponding to the UE in which the second network is the non-prohibited network.
S504, the second timer is overtime;
s505, the second network informs the UE that the first network recovers to normal through signaling, for example, the terminal is triggered to try to access the first network through connection release signaling, registration rejection signaling and the like;
s506, after receiving the information that the first network recovers from the second network, the UE tries to access the first network.
It should be noted that, in the network access triggering method provided in the embodiment of the present application, the execution subject may be a network access triggering device, or a control module in the network access triggering device, configured to execute the network access triggering method. In the embodiment of the present application, a method for a triggering device of a network access to execute a network access is taken as an example, and a triggering device of a network access provided in the embodiment of the present application is described.
