The following describes in detail the triggering scheme of the network access provided in the embodiment of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 2 shows a flow diagram of a method for triggering network access in an embodiment of the present application, and 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, determining that the target terminal needs to be accessed to a second network in the process of receiving the service from the first network by the target terminal.
In the embodiment of the application, when the target terminal is in normal service of the first network, the first network determines that the target terminal needs to access the second network when the second network is found to be available.
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 start to have a disaster, and the second network can normally provide services. For example, when the UE is in a connected state, the first network discovers that the first network starts to generate a disaster, and may not provide normal service, while the second network can provide the service normally. For example, some network elements of a portion of the first network may be involved in a disaster, but other network elements may still be 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 the connected state in the second network, the second network is in a disaster, the UE tries and accesses the first network, after the second network is restored to be normal, the first network determines that the second network is restored, and all UEs in the second network in the disaster state previously should perform network reselection, that is, all UEs in the second network in the disaster state previously need to access the second network.
S212, starting a first timer corresponding to the target terminal, wherein the duration of the first timers corresponding to the different terminals is not identical.
In this embodiment of the present application, each of the plurality of terminals corresponds to one first timer, and durations of the first timers corresponding to some of the plurality of first timers are different, or durations of the first timers corresponding to all of the plurality of terminals are different from each other.
And S214, triggering the target terminal to attempt to access the second network under the condition that the first timer is overtime.
In the embodiment of the application, in the process that a target terminal receives a service from a first network, the first network determines that the target terminal needs to be accessed to a second network, and then first network equipment starts a first timer, wherein for a plurality of different target terminals, the duration of the first timer is not identical; and then triggering the target terminal to attempt to access the second network when the first timer expires. Thus, the problem that a large number of target terminals attempt to access the second network at the same time, resulting in 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 duration 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 from a random value. By this possible implementation, it may be ensured that the target terminal accesses the second network randomly within a predetermined range, instead of accessing the second network simultaneously.
In one possible implementation, 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 the following:
(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) Subscription information of the target terminal. For example, subscription information such as priority or the like of the target terminal may be used as calculation reference information.
Optionally, the subscription information of the target terminal may include the 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 the option to calculate a longer timer to access the second network later and 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 determining the principle of 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 smaller than that 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 preferentially guaranteed that the home terminal of the first network changes to the second network, so that for the target terminal belonging to the first network, the duration of the corresponding first timer is smaller 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 or not and whether the target terminal is a home terminal of the first network or not can be determined according to the identification of the first network, the identification 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 determining the principle of the duration of the first timer may include: the duration of the first timer corresponding to a first terminal is smaller than the duration of the first timer corresponding to a second terminal, wherein 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 being the forbidden network of the second terminal means that the second terminal refuses to access the second terminal for reasons such as "PLMN non allowed" when the second terminal attempts to access the second network. For example, if the second network does not sign up for normal service with the first network, and if the UE is attempting to access the second network in the absence of a disaster, the second network is rejected by the cause "PLMN non allowed", i.e. the second network is a forbidden network for the UE. In this possible implementation, since the second network is a forbidden network of the second terminal, the second terminal may also be denied that it has attempted to access the second network earlier, and thus may leave the first network later and enter the second network later.
In practical application, whether the second network is the forbidden network of the target terminal or not can be determined according to the identification 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 can be determined.
In the foregoing possible implementation manner, optionally, when determining the duration of the first timer according to the target parameter information, the determining the principle of the duration of the first timer may include: if the second network and the first network are equivalent networks, the time length of the first timer corresponding to the first terminal is longer than the time length 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 a disaster occurs in the second network, the equivalent network of the second network (i.e., the first network) is changed, and when the second network is restored, since the first network is the equivalent network of the second network, the first network can provide normal service for the UE, and the UE can leave the first network later, so that the duration of the first timer corresponding to the UE can be longer. In this possible implementation, therefore, for a target terminal belonging to the second network, the corresponding first timer has a duration greater than that of a 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 determining the principle of the duration of the first timer may include: the time length of the first timer corresponding to the first terminal is longer than that of the first timer corresponding to the 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 and the first network do not sign up for normal service, and if a UE is attempting to access the first network in the absence of a disaster, and will be rejected by the reason "PLMN non allowed", 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 as soon as possible.
Fig. 3 shows another flow diagram of a method for triggering network access in an embodiment of the present application, and 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 discovers that the target network is available.
The original network discovery target network may be the same as that in the method 200 for determining that the target terminal needs to access the second network by the first network, and specifically, reference may be made to the related description in the method 200, which is not repeated herein.
S303, the original network starts a target timer corresponding to the UE.
The duration of the target timers corresponding to different UEs is not identical. The original network may determine the duration of the target timer by adopting a manner of determining the duration of the first timer corresponding to the target terminal by the first network in the method 200, which is specifically referred to the related description in the method 200 and will not be repeated herein.
S304, the target timer times out.
S305. the original network informs the UE that the target network is available, which may be signaled to the terminal, for example, a release message, or a registration reject message.
S306, after receiving the information available to the target network from the original network, the UE attempts to access the target network.
In the embodiment of the application, in the process that the UE receives the service from the original network, the original network discovers that the target network is available, and then the original network equipment starts a target timer corresponding to the UE; and then triggering the UE to attempt to access the target network when the target timer expires. Therefore, the problem that a large number of UE try to access the target network at the same time, so that the target network is congested can be avoided.
Fig. 4 shows a further flow diagram of a method for triggering network access in an embodiment of the present application, which 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.
S401. the ue is normally served in the first network.
S402, disaster occurs in the first network, and the second network serves normally.
S403, the first network starts a first timer corresponding to the UE.
For example, a partial network element disaster of the first network, but still a partial network element is available, the available network element may send a disaster notification to the UE, wherein the UE may be currently in, but is not limited to, a connected state.
The duration of the first timers corresponding to different UEs is not identical. The first network may determine the duration of the first timer by using a manner of determining the duration of the first timer corresponding to the target terminal by using the first network in the method 200.
For example, the first network may take on a random value for different UEs. 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), etc. as 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 lower priority UE may be given the longer timer calculated to require the UE to access the second network later and to provide normal service to the UE later.
(2) The second network is a network Equivalent to the first network, for example, the UE belongs to the first network, the second network is a peer Home network (EHPLMNE) of the Home network of the UE, and for the UE belonging to the first network, it is required to leave the first network as soon as possible to enter the second network to acquire the normal service as soon as possible, so that 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 network of the forbidden of the UE, for example, the second network does not sign up with the home network (i.e. the first network), when no disaster occurs, if the UE is attempting to access the second network and will be rejected by the reason "PLMN non allowed", the second network is a first timer corresponding to the UE of the forbidden network longer than a first timer corresponding to the UE of the second network is a non-forbidden network, i.e. the UE of the second network is forbidden to leave the first network later and enter the second network later.
S404, the first timer times out.
S405, the first network informs UE that a disaster occurs in the first network, and triggers the terminal to attempt to access the second network;
s406. After receiving the notification message in S405, the UE attempts to access in the second network.
Fig. 5 shows a further flowchart of a method for triggering network access in an embodiment of the present application, where the method 500 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 a normal service in the first network, the first network disasters, and the UE accesses to 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 access the second network by using other methods, which are not limited in the embodiments of the present application.
S502, the first network is restored to be normal.
S503, after the second network finds that the first network with the original disaster is recovered to be normal, the second network starts a second timer corresponding to the UE.
The duration of the second timers corresponding to different UEs is not identical. The first network may determine the duration of the second timer by using a manner of determining the duration of the first timer corresponding to the target terminal by the first network in the method 200.
For example, the second network may take on 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), etc. as calculation reference information.
Wherein the second network determining the duration of the second timer may comprise at least one of:
(1) A lower priority UE may be given the longer timer to calculate later requests for access to the first network.
(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 a duration of the second timer corresponding to the UE belonging to the first network is longer than a duration of the second timer corresponding to the UE not belonging to the first network.
(3) The second network is a forbidden network of the UE, for example, the second network and the first network do not sign up for normal service, i.e. if the UE is attempting to access the second network when no disaster occurs, if the UE is to be rejected by the cause "PLMN not allowed", 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, and the UE returns to its home network as soon as possible, so that the second network stops serving. Therefore, the duration of the second timer corresponding to the UE of the second network being the forbidden network is smaller than the duration of the second timer corresponding to the UE of the second network being the non-forbidden network.
S504, the second timer times out;
s505, the second network informs the UE that the first network is recovered to be normal through signaling, for example, through connection release signaling, registration rejection signaling and the like, and triggers the terminal to try to access the first network;
s506, after receiving the information of the first network restoring to normal sent by the second network, the UE tries to access the first network.
It should be noted that, in the triggering method of network access provided in the embodiment of the present application, the execution body may be a triggering device of network access, or a control module for executing the triggering method of network access in the triggering device of network access. In the embodiment of the present application, a triggering method for executing network access by a triggering device for network access is taken as an example, and the triggering device for network access provided in the embodiment of the present application is described.
