Description

Technical Field

Background

The 3rd generation partnership project (3 gpp) protocol provides that a terminal can regain service by a method such as disaster roaming when a network enters a disaster situation such that the network cannot provide service to the terminal. The indication message of network entry disaster situation can be issued by an authority and broadcast by a Public Warning System (PWS), and in order to minimize the network service interruption time of the terminal, the terminal should know the resident information of network entry disaster situation as soon as possible.

However, when the network enters a disaster due to a core network failure in the network, the failed core network cannot issue an indication message of the network entering the disaster to the base station, so that the base station cannot broadcast the indication message in a broadcast channel of the disaster network, and a terminal residing in the disaster network cannot know that the network has entered the disaster, and because the disaster network still generates radio waves, the terminal is likely to be mistakenly the network as normal, thereby causing long-time network service interruption of the terminal.

Therefore, how to timely notify a terminal residing in a disaster network when the network enters the disaster, so as to reduce the network service interruption time of the terminal is a problem to be solved.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations identical to the present application. Rather, they are merely examples of apparatus and methods that are identical to some aspects of the present application as detailed in the appended claims.

The flow diagrams depicted in the figures are exemplary only, and do not necessarily include all of the elements and operations/steps, nor must they be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations.

In the present application, the term "plurality" means two or more. "and/or" describes an association relationship of an association object, meaning that there may be three relationships, e.g., a and/or B may represent: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

As mobile communication services become an indispensable service in people's daily lives, various attempts are being made by various mobile service providers to prevent service interruption. For example, a mobile service provider uses or installs multiple wired networks such as mobility management function network elements (access and mobility management function, AMF), mobility management entities (mobility management entity, MME) during the core network duration of a wireless network, so that communication service interruption can be prevented by performing backups in other network nodes even if there is a problem in one network node. However, in the event of a disaster such as a fire or an earthquake, all communication cables connected to the outside from one node of the wireless network may be lost, and thus, it is highly likely that service interruption is caused regardless of whether a plurality of AMFs, MMEs are implemented.

Thus, the terminal can be re-served by disaster roaming, i.e., if the terminal cannot receive the communication service due to a problem with the network of the mobile service provider to which it subscribes, the terminal can roam to other surrounding mobile service providers and receive the communication service.

In the related art, when power supply to the wireless network is interrupted, the wireless network does not generate any radio waves, and thus, the terminal can identify a problem of subscribing to the network by detecting a radio wave reception failure; or, the core network of the wireless network entering the disaster sends an indication message of network entering the disaster to the base station so that the base station informs the terminal residing in the disaster network of the problem of subscribing the network.

However, when a network enters a disaster due to a failure of a core network in the network, if a wired communication line between a wireless network and the core network is cut off, the core network cannot issue an indication message indicating that the network enters the disaster to a base station, and a terminal residing in the disaster network cannot know that the network has entered the disaster, and the wireless network still generates radio waves, so that the terminal cannot quickly identify a problem of communication service, thereby causing a long-time interruption of network service for the terminal.

Therefore, the application provides a fault alarm method, so that the terminal can quickly identify the problem of communication service, and the network service interruption time of the terminal is reduced.

The following describes a fault alarm method provided by an embodiment of the present application, where fig. 1 is a schematic diagram of a network architecture related to the fault alarm method in the present application. As shown in fig. 1, the network architecture includes a network detection end 110, a plurality of public land mobile networks (public land mobile network, PLMNs) 120, a shared base station 130, and a terminal 140.

In this network architecture, the network detection end 110 is communicatively connected to each PLMN. For example, the network detection end 110 may be a cell broadcast entity (Cell Broadcast Entity, CBE) that collects, sorts, schedules, etc. the original broadcast information of the content provider (Internet Content Provider, ICP).

PLMN120 is a network established and operated by a government or government-approved network operator for the purpose of providing land mobile services to the public. The PLMNs 120 in fig. 1 (e.g., the PLMNs 120-1 and 120-2 in fig. 1) may be PLMNs provided by one or more different operators, or may be PLMNs corresponding to different wireless communication systems, for example: global system for mobile communications (global system for mobile communications, GSM), general packet radio service (general packet radio service, GPRS), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), time division code division multiple access (time-division code division multiple access, TD-SCDMA), long term evolution (long term evolution, LTE), new air interface for fifth generation mobile communication technology (5th generation mobile networks new radio,5G NR), and future other technical standard architecture.

Each PLMN 120 includes a Core Network (CN) device 121. The core network device 122 may be a mobility management entity (mobile management entity, MME), a gateway (gateway), a Network Function (NF) of a Control Plane (CP) and a network function of a User Plane (UP) in the 5G network, for example, a common control plane network function (common CP NF, CCNF), a session management network function (session management NF, SMF), and the like.

The shared base station 130 exists in the user terminal and provides a connection of the terminal to the core network, the shared base station 130 may be a next generation radio access network (Next Generation Radio Access Network, NG-RAN), the NG-RAN may be a base station in GSM or CDMA (base transceiver station, BTS), a base station in WCDMA (NodeB, NB), an evolved base station in LTE (evolutional node b, eNB or eNodeB), or a relay station, an access point, network equipment in future PLMNs, etc.

The terminal 140 is communicatively connected to the shared base station 130, which may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc. The terminal 140 may refer broadly to one of a plurality of terminals, the present embodiment being illustrated only by the terminal 140. Those skilled in the art will recognize that the number of terminals may be greater or lesser. Such as the above-mentioned terminals may be only one, or the above-mentioned terminals may be several tens or hundreds, or more. The embodiment of the application does not limit the number of terminals and the equipment type.

Referring to fig. 2, fig. 2 is a flowchart illustrating a fault alerting method according to an exemplary embodiment of the present application. The fault alerting method may be applied to the network architecture shown in fig. 1 and specifically performed by the shared base station 130 in the network architecture. As shown in fig. 2, the method at least includes steps S210 to S230, and is described in detail as follows:

step S210, receiving network fault information forwarded by PLMN; the network fault information is information sent to a plurality of PLMNs when the network detection end detects that the PLMNs have faults, and the network fault information carries the identification of the faulty PLMNs.

The shared base station refers to a base station shared by a radio access network, where the radio access network shared refers to a physical cell that can be shared by a plurality of networks, and a common expression is that one physical cell is shared by a plurality of logical cells, different logical cells may belong to different PLMNs, and a physical cell that is shared by a plurality of logical cells is also referred to as a shared cell, and the plurality of logical cells may be referred to as a plurality of logical cells of the shared cell. The physical cell may be understood as a cell corresponding to the physical resource, for example, may be identified by a frequency point and a physical cell identifier (physical cell identifier, PCI). The logical cell may be identified by a cell global identity (cell global identifier, CGI), i.e. the logical cell may refer to a cell identified by a CGI consisting of a PLMN identity and a cell identity (cell ID).

By way of example, the network failure information may be public warning system (Public Warning System, PWS) information, which is a system for warning disasters and other emergency situations, and the PWS defined in 3GPP may be applied to different communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS) and long term evolution (Long Term Evolution, LTE). The PWS includes an earthquake tsunami warning system (Earthquake and Tsunami Warning System, ETWS), a commercial mobile warning system (Commercial Mobile Alert System, CMAS), and an emergency notification system (Emergency Alert System, EAS).

The network fault information carries the identification of the faulty PLMN, and the identification of the faulty PLMN is used for identifying the faulty PLMN.

Optionally, the network failure information may further include information such as network quality information of the failed PLMN, and network failure cause, which is not particularly limited in the present application.

Step S220, judging whether network fault information forwarded by the fault PLMN is received or not according to the identification of the fault PLMN.

If the shared network receives the network fault information forwarded by the faulty PLMN, it indicates that the core network of the faulty PLMN can normally communicate, and it can send the network fault information to the registered terminal; if the shared network does not receive the network fault information forwarded by the faulty PLMN, the core network of the faulty PLMN cannot normally communicate, and the core network cannot send the network fault information to the registered terminal.

In some embodiments, the process of determining whether network failure information forwarded by the failed PLMN is received according to the identity of the failed PLMN includes: according to the identification of the failed PLMN, the historical network failure information of the failed PLMN is confirmed; judging whether the historical network fault information is matched with the network fault information forwarded by the PLMN; if the historical network fault information is not matched with the network fault information forwarded by the PLMN, judging that the network fault information forwarded by the faulty PLMN is not received.

And the sharing base station carries out association storage on the received network fault information and the identification of the PLMN for forwarding the network fault information so as to obtain a historical network fault information list corresponding to each PLMN.

And then, obtaining a historical network fault information list corresponding to the fault PLMN through the identification of the fault PLMN, wherein the historical network fault information list comprises all historical network fault information forwarded by the fault PLMN to the shared base station in a historical time period, and the historical time period can be 1 hour, 1 day or 1 week before the current moment, so that the application is not limited to the historical time period.

Further, whether the historical network fault information list of the faulty PLMN contains network fault information forwarded by the PLMN received by the sharing base station is queried. For example, the information identification of each historical network fault information in the historical network fault information list is obtained and is matched with the information identification of the network fault information forwarded by the PLMN received by the sharing base station, if the matching is successful, the fact that the corresponding network fault information is forwarded by the faulty PLMN to the sharing network is indicated; if the matching fails, the failure PLMN is indicated to not forward the corresponding network failure information to the shared network.

For example, the information identity identifier message identifier and the information serial number serial number fields of the historical network fault information received by the PLMN are stored in the historical network fault information list of each PLMN, whether the historical network fault information with the information identity identifier corresponding to the historical network fault information and the information serial number consistent with the information identity identifier corresponding to the network fault information forwarded by the PLMN exists in the faulty PLMN is detected, if so, the historical network fault information and the network fault information forwarded by the PLMN are the same information, and the faulty PLMN is indicated to forward the corresponding network fault information to the shared network; if the information is not present, the information which is the same as the network fault information forwarded by the PLMN is not present in the historical network fault information list of the faulty PLMN, and the fact that the faulty PLMN does not forward the corresponding network fault information to the shared network is indicated.

Step S230, if the network failure information forwarded by the failed PLMN is not received, broadcasting the network failure information forwarded by the PLMN in a broadcast channel corresponding to the failed PLMN.

The shared base station broadcasts the network fault information indicating that the fault PLMN enters the disaster in a broadcast channel corresponding to the fault PLMN, so that a terminal corresponding to the fault PLMN receives the network fault information. Optionally, the shared base station updates the status information of each PLMN according to the received network failure information. For example, the shared base station stores a PLMN state information list, and when a PLMN can provide network services for a terminal, state information of the PLMN in the PLMN state information list is in a normal state; when the PLMN can not provide network service for the terminal, if the network fault information received by the sharing base station indicates that the PLMN enters a disaster, the state information of the PLMN in the PLMN state information list is updated to be in an abnormal state. When the shared base station broadcasts network fault information of the fault PLMN entering the disaster in a broadcast channel corresponding to the fault PLMN, the PLMN state information list can be broadcast simultaneously, so that the terminal selects a target PLMN capable of providing network service according to the PLMN state information list, and the terminal accesses the target PLMN to acquire network service again.

For example, referring to fig. 3, the shared base station shares the network failure information to the terminals corresponding to the failed PLMN, where the PLMN120-1 and the PLMN 120-2 are shown by the shared base station, the logical cell in the PLMN120-1 is the logical cell 1, and the logical cell in the PLMN 120-2 is the logical cell 2: as shown in fig. 3, the shared base station manages the logical cell 1 and the logical cell 2, where the logical cell 1 and the logical cell 2 respectively include terminals, and if the identifier of the faulty PLMN carried in the network fault information received by the shared base station is PLMN120-1, and if the historical network fault information matched with the network fault information is not found in the historical network fault information of PLMN120-1, it is determined that the network fault information forwarded by PLMN120-1 is not received, so that the network fault information is broadcasted in the logical cell 1 to notify the terminal PLMN120-1 in the logical cell 1 that the disaster has been entered.

If the shared base station does not receive the network fault information forwarded by the faulty PLMN, the terminal corresponding to the faulty PLMN cannot know that the faulty PLMN has entered the disaster, so that the shared base station receives the network fault information indicating that the faulty PLMN has entered the disaster from other PLMNs, and broadcasts the network fault information to the terminal corresponding to the faulty PLMN after detecting that the faulty PLMN cannot issue a message, so that the terminals can quickly identify the problem of communication service, the network service interruption time of the terminal is reduced, and the user experience is improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating a fault alerting method according to an exemplary embodiment of the present application. The fault alerting method may be applied to the network architecture shown in fig. 1 and specifically performed by the PLMN120 in the network architecture. As shown in fig. 4, the method at least includes steps S410 to S420, and is described in detail as follows:

step S410, receiving network fault information sent by a network detection end; the network fault information is sent to the PLMN when the network detection end detects that the PLMN has the fault, and the network fault information carries the identification of the PLMN.

And receiving network fault information sent by a network detection end, wherein the network fault information carries the identification of a fault PLMN, and the identification of the fault PLMN is used for identifying the fault PLMN.

It can be understood that the identifier of the faulty PLMN carried in the network fault information may be consistent with the identifier of the PLMN that receives the network fault information, that is, the PLMN that receives the network fault information is the faulty PLMN indicated by the network fault information; the identity of the faulty PLMN carried in the network fault information may not be consistent with the identity of the PLMN receiving the network fault information, i.e. the PLMN receiving the network fault information is not the faulty PLMN indicated by the network fault information.

Step S420, the network fault information is forwarded to the shared base station, so that when the shared base station judges that the network fault information forwarded by the faulty PLMN is not received according to the identification of the faulty PLMN, the network fault information forwarded by the PLMN is broadcasted in a broadcast channel corresponding to the faulty PLMN.

And the PLMN receiving the network fault information forwards the network fault information to a corresponding shared base station, so that when the shared base station determines that the network fault information forwarded by the fault PLMN is not received, the network fault information indicating that the fault PLMN enters a disaster situation is broadcasted in a broadcast channel corresponding to the fault PLMN, and a terminal corresponding to the fault PLMN receives the network fault information.

The PLMN can broadcast network fault information to all base stations or shared base stations which have connection relation with the PLMN; only the network failure information may be forwarded to the base station or the shared base station that matches the identity of the failed PLMN; the network failure information may also carry information of the base station to be broadcasted, and the PLMN may broadcast the network failure information to all base stations or shared base stations corresponding to the information of the base station to be broadcasted, which is not particularly limited in the present application.

In some embodiments, the network failure information carries the base station information to be broadcasted, and the process of forwarding the network failure information to the shared base station in step S420 may include the following steps: acquiring a shared base station set of a PLMN, wherein the shared base station set comprises shared base stations with connection relation with the PLMN; taking a sharing base station matched with the base station information to be broadcasted in the sharing base station set as a target sharing base station; and sending the network fault information to the target sharing base station.

It should be noted that, the shared base station set of each PLMN is used for storing the shared base stations having a connection relationship with the corresponding PLMN, and the number of the shared base stations in the shared base station set may be one or more, which is not particularly limited in the present application. The target shared base station matched with the base station information to be broadcasted in the shared base station set refers to a base station contained in the base station information to be broadcasted.

For example, referring to fig. 5, the PLMNs include PLMN 120-1, PLMN 120-2 and PLMN 120-3, the shared base station 130-1 is shared to PLMN 120-1 and PLMN 120-2, the shared base station 130-2 is shared to PLMN 120-2 and PLMN 120-3, and the PLMN is described for forwarding network failure information to the shared base station: as shown in fig. 5, PLMNs 120-1, 120-2, and 120-3 each receive network failure information, and the identity of the failed PLMN carried in the network failure information is PLMN 120-1. Wherein, the PLMN 120-1 fails to issue the indication information.

Therefore, the PLMN 120-2 obtains the sharing base stations having the connection relationship, including the sharing base station 130-1 and the sharing base station 130-2, and the PLMN 120-2 uses the sharing base station matched with the base station information to be broadcasted in the sharing base station set as the target sharing base station. For example, the base station to be broadcasted in the base station information to be broadcasted is the shared base station 130-1, and the shared base station set of the PLMN 120-2 includes the shared base station 130-1, the network failure information is sent to the shared base station 130-1.

Further, the network fault information is forwarded to the target shared base station matched with the identifier of the faulty PLMN, so that the target shared base station receives the network fault information indicating that the faulty PLMN enters the disaster condition from other PLMNs, and after detecting that the faulty PLMN cannot send a message, the network fault information is broadcasted to the terminal corresponding to the faulty PLMN, so that the terminal can quickly identify the problem of communication service, the network service interruption time of the terminal is reduced, and the user experience is improved.

Referring to fig. 6, fig. 6 is a flowchart illustrating a fault alerting method according to an exemplary embodiment of the present application. The fault alerting method may be applied to the network architecture shown in fig. 1, and is specifically executed by the network detection end 110 in the network architecture. As shown in the figure, the method at least includes steps S610 to S620, and is described in detail as follows:

in step S610, if a faulty PLMN is detected, network fault information is generated according to the identity of the faulty PLMN.

The network detection end may periodically detect whether each PLMN has a fault, for example, each PLMN sends a heartbeat data packet to the network detection end, so that the network detection end obtains the operation condition of each PLMN through the heartbeat data packet, and when detecting that the PLMN has a fault, generates network fault information according to the identifier of the PLMN.

The network detection end receives the fault PLMN notification information sent by the third party platform, obtains that the fault PLMN exists according to the identifier of the fault PLMN contained in the fault PLMN notification information, and generates network fault information according to the identifier of the fault PLMN. Wherein the third party platform may be an operator.

Step S620, network fault information is sent to a plurality of PLMNs, so that the PLMNs forward the received network fault information to the shared base station, and when the shared base station detects that the network fault information forwarded by the faulty PLMN is not received according to the identification of the faulty PLMN, the network fault information forwarded by the PLMN is broadcasted in a broadcast channel corresponding to the faulty PLMN.

The network detection end sends network fault information to the PLMN, so that the PLMN forwards the received network fault information to the shared base station, and when the shared base station determines that the network fault information forwarded by the fault PLMN is not received, the network fault information indicating that the fault PLMN enters a disaster situation is broadcasted in a broadcast channel corresponding to the fault PLMN, so that a terminal corresponding to the fault PLMN receives the network fault information.

The network detection end can broadcast network fault information to all PLMNs which have connection relation with the network detection end; only the network failure information may be sent to PLMNs that match the identity of the failed PLMN; other platforms may also inform the network detection end of the PLMN to be transmitted, so that the network detection end may transmit network fault information, which is not particularly limited in the present application.

In some embodiments, the process of transmitting the network failure information to the plurality of PLMNs in step S620 may include the steps of: acquiring a shared base station set of each PLMN, wherein the shared base stations in the shared base station set have a connection relationship with the corresponding PLMN; taking a shared base station in a shared base station set of the fault PLMN as a reference shared base station, and taking a PLMN corresponding to the shared base station set containing the reference shared base station as a target PLMN; and sending the network fault information to the target PLMN.

For example, referring to fig. 7, the network detection end is connected to the PLMN 120-1, the PLMN 120-2 and the PLMN 120-3, the shared base station 130-1 is shared to the PLMN 120-1 and the PLMN 120-2, the shared base station 130-2 is shared to the PLMN 120-2 and the PLMN 120-3, and the description is given that the network detection end sends the network failure information to the PLMN: the network detection end stores a connection relation table between each PLMN and each shared base station, and confirms the PLMN to be transmitted by inquiring the connection relation between each PLMN and each shared base station so as to transmit network fault information to the PLMN to be transmitted. If the connection relationship between the PLMN and the shared base station indicates that the PLMN 120-1 has a connection relationship with the shared base station 130-1, the PLMN 120-2 has a connection relationship with the shared base station 130-1 and the shared base station 130-2, and if the identity of the faulty PLMN is PLMN 120-1, referring to the shared base station as shared base station 130-1, querying the connection relationship table to obtain that the PLMN to be transmitted having a connection relationship with the shared base station 130-1 is PLMN 120-2, and transmitting network fault information to PLMN 120-2.

In some embodiments, the number of target PLMNs is at least one; the process of transmitting the network failure information to the target PLMN may include: confirming the network fault information sending priority of the target PLMN according to the number of the reference shared base stations contained in the shared base station set of the target PLMN; and according to the network fault information sending priority, sending the network fault information to the target PLMN.

Illustratively, the faulty PLMN is PLMN 120-1, the target PLMN comprises PLMN 120-1, PLMN 120-2 and PLMN 120-3, the shared base station set of PLMN 120-1 comprises shared base station 130-1, shared base station 130-2 and shared base station 130-3, the shared base station set of PLMN 120-2 comprises shared base station 130-1 and shared base station 130-2, the shared base station set of PLMN 120-3 comprises shared base station 130-1 and shared base station 130-2, and the PLMN is described as forwarding network fault information to the shared base stations. Since the faulty PLMN is PLMN 120-1, the reference shared base stations include shared base station 130-1, shared base station 130-2 and shared base station 130-3, and the number of reference shared base stations included in PLMN 120-1 is 3, the number of reference shared base stations included in PLMN 120-2 is 2, and the number of reference shared base stations included in PLMN 120-3 is 1. Further, according to the number of reference shared base stations included in the shared base station set of the target PLMN, confirming that the network failure information transmission priority order of each target PLMN is PLMN 120-1 over PLMN 120-2, and PLMN 120-2 over PLMN 120-3. Then, the network failure information is transmitted to the PLMN 120-1 according to the priority of each target PLMN, and then to the PLMN 120-2, and then to the PLMN 120-3.

It can be understood that, the greater the number of reference shared base stations included in the shared base station set corresponding to the PLMN, the greater the terminal duty ratio of the network fault information to be sent, which is matched with the PLMN, is indicated, so that in order to ensure that the terminal corresponding to the faster term of the network fault PLMN sends the network fault information, according to the number of reference shared base stations included in the shared base station set of the target PLMN, the network fault information sending priority of the target PLMN is confirmed, so as to send the network fault information to the target PLMN according to the network fault information sending priority, and further reduce the network service interruption time of the terminal.

Referring to fig. 8, fig. 8 is an interaction diagram of a fault alert method according to an exemplary embodiment of the present application, including a network detection end CBE, a cell broadcast center (cell broadcast center, CBC), a PLMNA in a normal operating state, a PLMND in a fault state, a shared base station NG-RAN, and a terminal UE, which are described in detail as follows:

in step S810, the UE registers in and obtains service from the PLMND.

In step S820, the CBE knows that the PLMND is in a fault state, and sends network fault information to the CBC, where the network fault information is used to instruct the PLMND to enter a disaster situation.

In step S830, the CBC selects target PLMNs in the broadcast area according to the identifier of the PLMND in the network failure information, and issues the network failure information and the broadcast parameter information to the target PLMNs through the Write-Replace Warning Request NG-RAN message.

The broadcast parameter information may include shared base station information (list of NG-RAN TAIs) that needs to be broadcast, among others.

In step S840, after receiving the network failure information and the broadcast parameter information, the target PLMN sends a reception acknowledgement to the CBC through the Write-Replace Warning Confirm NG-RAN message.

In step S850, after receiving the reception acknowledgement information of the target PLMN, the CBC feeds back a success notification to the CBE.

In step S860, the target PLMN selects NG-RANs to be broadcast according to list of NG-RANs TAIs in the broadcast parameter information, and forwards the network failure information to the NG-RANs.

In step S870, the NG-RAN checks to find that the network failure information is not received from the PLMND, and then the NG-RAN broadcasts the network failure information on the broadcast channels of the PLMNA and the PLMND according to the broadcast parameter information issued by the CBC.

In step S880, the UE residing in the PLMND listens to the network failure information broadcast, and knows that the PLMND enters the disaster, and the UE tries to access other PLMNs to obtain services.

In step S890, the NG-RAN sends a message broadcast success notification to the target PLMN.

For example, referring to fig. 9, in step S910, the CBC sends network failure information to the PLMN; step S920, PLMN forwards network failure information to NG-RAN; step S930, the NG-RAN judges whether the network failure information is received from the PLMND, if so, step S940 is executed to broadcast the network failure information on the broadcast channel of the PLMNA; if not, step S950 is performed, and the piece of network failure information is broadcast on the broadcast channels of the PLMNA and the PLMND.
