All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.

Fig. 1 is a schematic diagram of a remote disaster recovery networking scenario in the prior art, and as shown in fig. 1, a broadband Trunking Core Network TCN1 (traversing Core Network) and a broadband Trunking Core Network TCN2 are provided, where one of the broadband Trunking Core Network TCN1 and the broadband Trunking Core Network TCN2 serves as a main Core Network, and the other serves as a standby Core Network. The main core network and the standby core network are the existing states of the core networks, the main core network can be switched to the standby core network in some scenes, and the standby core network can be switched to the main core network. Under normal conditions, the main core network is used for processing the service request of the cluster terminal. In addition, the base station T-eNB is connected with TCN1 and TCN2 in an S1-T mode. The broadband cluster core network comprises equipment such as a subscription data management authentication center (eHSS), a data gateway xGW, a cluster control functional entity (TCF), a cluster media functional entity (TMF), a mobile management entity (eMMC) and the like; the eHSS comprises a subscription data management HSS and a cluster subscription data management THSS; said xGW comprises a serving gateway SGW and a PDN gateway PGW.
Fig. 2 is a schematic diagram of a failure weakening scenario in a single subnet in the prior art, where the scenario includes a network management platform, a cluster core network, a base station 1 and a base station 2, where the base station 1 and the base station 2 respectively include a plurality of cluster terminals, the base station 1 and the base station 2 respectively communicate with the cluster core network, and the gateway platform is used to manage the cluster core network. When the S1 link between the base station 1 and the cluster core network is normally connected, the cluster terminal may access the cluster core network to normally perform the cluster service, and when the S1 link between the base station 1 and the cluster core network is disconnected, the base station may enter a failure weakening mode and instruct the cluster terminal to re-access the failed single station to perform the cluster service. The failure single station refers to the name of the base station when the base station is disconnected with the core network and is in an isolated state.
Fig. 3 is a schematic diagram of a networking scenario of remote disaster recovery and failure weakening in the prior art, and as shown in fig. 3, in the networking scenario of remote disaster recovery and failure weakening, since the B-TrunC standard only defines the implementation of failure weakening in a single subnet scenario, and failure weakening is not separately defined for the networking scenario of remote disaster recovery and failure weakening, when all S1 links of a base station are broken, the base station can enter a failure weakening mode, that is, when an S1 link between the base station and a primary core network is broken and an S1 link between the base station and a standby core network is also broken, the base station enters the failure weakening mode.
However, when the S1 link between the base station and the main core network is broken and the S1 link between the base station and the standby core network is normal, the trunking terminal will access the standby core network, and the standby core network does not work, and the trunking terminal will fail to register, and thus the trunking service cannot be performed on the standby core network. For example, in rail transit, the requirement on the reliability of the cluster terminal service processing is high, and if the base station does not enter the failure weakening mode and the standby core network is not in a working state, the cluster terminal cannot perform the cluster service.
Based on the technical problem, the method and the device add a judgment condition for entering the fault weakening to the base station, that is, when an S1 link between the base station and the main core network is interrupted and an S1 link between the base station and the standby core network is normal, the base station enters the fault weakening mode, the cluster service of the cluster terminal is processed through the single fault station, and the problem that the cluster service of the cluster terminal cannot be processed in the scene is solved.
Fig. 4 is a schematic flowchart of a processing method for failure weakening according to an embodiment of the present invention, as shown in fig. 4, where the method is applied to a base station, and the method includes:
s401, if the communication link between the master core network and the slave core network is detected to be interrupted and the communication link between the master core network and the slave core network is detected to be normal, determining to enter a fail-soft mode.
In this embodiment, the base station is configured to communicate with a core network, where the core network includes a main core network and a standby core network.
Detecting communication link interruption between main core networks, wherein the communication link interruption comprises link interruption caused by port looseness between the base station and main core network equipment; or link interruption caused by network cable looseness between the base station and the main core network equipment; or other link outages due to human causes, etc.
Fig. 5 is a schematic diagram of entering a failure weakening mode in a remote disaster recovery and failure weakening networking scenario according to an embodiment of the present invention. As shown in fig. 5, when it is detected that the communication link between the primary core network and the standby core network is broken and the communication link between the primary core network and the standby core network is normal, the base station enters a fail-soft mode.
If the mobile terminal does not enter the fail-soft mode, because the link between the base station and the standby core network is normal, the base station will access the trunking terminal originally accessed to the main core network to the standby core network, but because the standby core network is in the standby state, the service request of the trunking terminal will not be processed, and therefore, the service request of the trunking terminal will not be responded in this scenario.
In the above scenario, after entering the failure weakening mode, the service request of the cluster terminal may be processed.
S402, sending a first notification message to a cluster terminal in a failure weakening mode, wherein the first notification message is used for indicating the cluster terminal to access a local core network module in a base station; the local core network module is used for receiving a service request sent by the cluster terminal after accessing the local core network module and processing the service request.
Specifically, in the failure weakening mode, the base station may send a first notification message to the trunking terminal, and when receiving the first notification message, the trunking terminal may perceive that the base station is in the failure weakening mode, and then the trunking terminal may send an access request to the base station again, and at this time, the base station may access the trunking terminal to a local core network module inside the base station.
The local core network module is arranged in the base station, the local core network is composed of an integrated EPC (evolved Packet core) module, and when the local core network is in a failure weakening mode, the integrated EPC module replaces a main core network to process a service request of a cluster terminal. The integrated EPC module is also used for processing the registration request of the cluster terminal instead of the main core network. The local core network can realize services including single call, group call, full broadcast call and the like.
In the processing method for failure weakening provided in this embodiment, when it is detected that a communication link with the primary core network is interrupted and a communication link with the standby core network is normal, it is determined that a failure weakening mode is entered; sending a first notification message to a cluster terminal in a failure weakening mode, wherein the first notification message is used for indicating the cluster terminal to access a local core network module in a base station; the local core network module is used for receiving a service request sent by the cluster terminal after accessing the local core network module and processing the service request.
In one embodiment, the method further comprises: if the communication link between the main core network and the main core network is detected to be recovered to be normal, determining to exit the failure weakening mode; and when the fault weakening mode exits, closing a local core network module in the base station, and sending a second notification message to the cluster terminal, wherein the second notification message is used for indicating the cluster terminal to access the main core network, so that the main core network processes a service request of the cluster terminal.
Fig. 6 is a schematic diagram of a remote disaster recovery and graceful degradation networking scenario exiting a graceful degradation mode according to an embodiment of the present invention. In this embodiment, when the communication link between the main core network and the base station returns to normal, the service request of the trunking terminal is processed continuously through the main core network. Specifically, when the base station detects that the link with the primary core network is restored to normal, the base station exits the fail-soft mode.
After exiting the failure weakening mode, on one hand, the base station closes the internal local core network module, and prevents the local core network module from continuously processing the service request of the trunking terminal. On the other hand, the base station sends a second notification message to the trunking terminal, and when the trunking terminal receives the second notification message, the trunking terminal senses that the base station exits the failure weakening mode, and at this time, the trunking terminal accesses the main core network, and the main core network processes the service request of the trunking terminal.
After a communication link between the base station and the main core network is recovered to be normal, the main core network processes the service request of the trunking terminal, so that the service request of the trunking terminal can be ensured to be normally carried out.
In one embodiment, if it is detected that the communication link with the primary core network is interrupted and the communication link with the standby core network is normal, determining to enter a failure-weakened mode includes:
receiving a master/standby notification message sent by a core network; if the received master/slave notification message contains a first identifier, determining a core network which sends the master/slave notification message containing the first identifier as a master core network; if the received master/slave notification message contains a second identifier, determining that the core network which sends the master/slave notification message containing the second identifier is a slave core network; if the S1 message sent by the main core network is not received within the preset time and the S1 message sent by the standby core network is received, determining that the communication link between the main core network and the standby core network is interrupted and the communication link between the standby core network and the standby core network is normal; and when the communication link between the main core network and the standby core network is detected to be interrupted and the communication link between the standby core network and the standby core network is normal, entering a failure weakening mode.
Specifically, when determining to enter the failure-weakening mode, it is necessary to determine a communication link state between the base station and the core network and a main/standby state of the core network corresponding to the link state. The process adopts two mechanisms, one is a link detection mechanism, and the other is a master/standby notification mechanism.
Specifically, the master/slave notification mechanism is that the master core network and the slave core network send master/slave notification messages to the base station every a first preset time, where the master/slave notification messages that the master core network and the slave core network send to the base station respectively are messages including different identifiers, and are respectively a first identifier and a second identifier. For example, the master/slave notification message sent by the master core network to the base station is 0, and the master/slave notification message sent by the master core network to the base station is not 0. When receiving the master/standby notification message, the base station determines the master/standby state of the core network that sends the master/standby notification message according to the identification information. For example, when the received active/standby notification message is 0, the core network that sends the active/standby notification message may be determined as the standby core network, and when the received active/standby notification message is not 0, the core network that sends the active/standby notification message may be determined as the main core network.
Specifically, the link detection mechanism is to receive an S1 message sent by the core network at intervals of a second preset time, and when the S1 message is not received, it may indicate that the communication link is interrupted; when the S1 message is detected, it may indicate that the communication link is normal. The base station and the core network perform signaling interaction through an S1 interface, where the signaling information is represented as an S1 message.
The interval of the first preset time for the main core network and the standby core network to send the main/standby notification message is smaller than the interval of the second preset time for the S1 message received by the base station, so that it can be ensured that the base station can determine whether the core network is the main core network or the standby core network when determining whether the communication link with the core network is interrupted.
And finally, when the communication link between the master core network and the standby core network is determined to be interrupted and the communication link between the master core network and the standby core network is normal, determining to enter a failure weakening mode. Then, in a networking scenario where disaster recovery from different places is accompanied by failure weakening, when communication links between the base station and the primary core network and the standby core network are all interrupted, or when a communication link between the base station and the primary core network is interrupted and a communication link between the base station and the standby core network is normal, the base station enters a failure weakening mode.
Through a link detection mechanism and a master-slave notification mechanism, the base station can determine the state of the core network and whether a communication link between the base station and the core network is normal.
In an embodiment, the master/standby notification message is determined according to heartbeat information between the master core network and the standby core network; and when the heartbeat information between the main core network and the standby core network is abnormal, the standby core network is switched to be the main core network.
In this embodiment, the determination of the active/standby notification message is determined based on heartbeat information. The standby core network monitors heartbeat information sent by the main core network and determines whether the main core network is in an abnormal state according to a monitoring result. When the heartbeat information monitored by the standby core network is normal, the main core network is indicated to be in normal operation, and the switching of the core networks cannot be carried out. When the heartbeat information monitored by the standby core network is abnormal, which indicates that the main core network is abnormal, the standby core network and the main core network are switched. When equipment in the main core network fails, the heartbeat information sent to the standby core network is stopped, or the sent heartbeat information is in an abnormal state.
The heartbeat messages between the main core network and the standby core network can be used for determining the state of the main core network, and further determining whether to switch the state of the core network.
In one embodiment, after the standby core network and the main core network are switched, the cluster terminal processed by the main core network after switching is the same as the cluster terminal processed by the main core network before switching.
In this embodiment, when the standby core network is switched to the main core network, the cluster terminal to which the processed service request belongs is the same as the cluster terminal to which the service request processed by the original main core network belongs. When the main core network is in an abnormal state, the standby core network can be switched to the main core network and replaces the main core network to process the service request of the corresponding cluster terminal. The main core network is in an abnormal state, which means that the main core network is in a power-off state or needs to be upgraded.
