Fig. 1 is an implementation environment diagram of a synchronization method according to an embodiment of the present invention. As shown in the figure, the schematic diagram of the LTE network is a hierarchical structure, in which each level is provided with a plurality of nodes, the first level is node 100, the second level is node 200-. In this embodiment, the synchronization method is applied to each node, where each node may be Core network equipment, such as EPC (Evolved Packet Core) equipment, and each node may be used for terminal access in a certain area. As shown in the figure, the node 300 and the node 302 are located in different areas, and when a terminal belonging to the node 300 roams to an area covered by the node 302, since data information of the terminal is stored in the node 300, data of the node 300 needs to be synchronized in the node 302 in time to support terminal roaming. In this embodiment, the node 300 first sends the relevant data to the upper node 201, the upper node 201 further sends the data to the upper node 100, and the upper node 100 issues the data to the node 203, and the node 203 issues the data to the node 302, so that the data is unified and consistent, and the terminal roaming is supported.
Fig. 2 is a signal flow diagram of a synchronization method according to an embodiment of the present invention. The signal flow between the current node 300 and the upper node 201 is schematically shown, and it is understood that the present invention is also applicable to the signal flow between the node 201 and the upper node 100. As shown in the figure, when the node 300 is started, the address information of the upper node 201 is obtained by reading a preset adjacency list; the node 300 sends heartbeat request information to the upper node 201; after receiving the heartbeat request message, the upper node 201 replies a corresponding heartbeat response message; after receiving the heartbeat response message, the node 300 sends all cache messages on the node 300; when a cross-regional terminal requests to access the node 300, the node 300 sends a user subscription information request to the upper node 201 according to the request of the terminal; the superior node 201 receives the request and issues the user subscription information belonging to the node according to the request; the node 300 updates data according to the subscription information of the user, thereby realizing data consistency and unification in the network and realizing roaming support for the cross-regional terminal.
Fig. 3 is a flowchart of a synchronization method according to a first embodiment of the present invention. In this embodiment, the synchronization method is applied to a node device, which may be an EPC device, and network elements such as an MME (Mobile management entity), an SGW (Serving GateWay), a PGW (Packet data network GateWay), and an HSS (Home Subscriber Server) are integrated on the node device, and the network elements are presented in a form of being concentrated on one Server or in one small-sized machine frame device. The synchronization method in this embodiment is applied to information synchronization between a node device and an upper node, for example, the synchronization method may be applied to information synchronization between the node 300 and the upper node 201 shown in fig. 1, and may also be applied to information synchronization between the node 201 and the upper node 100 shown in fig. 1. The synchronization method comprises steps S101-S105.
In step S101, an adjacency information table preset by the current node is read, where the adjacency information table includes address information of a higher node.
Specifically, when a small LTE network is established, an adjacency information table of each node device is configured, where the adjacency information table includes address information of a higher node, and optionally, the address information refers to address information of a HSS of the higher node. In addition, each node device is also provided with corresponding user subscription data in an initial state, so as to provide services for terminals in a preset area. When the node device is started or replies from a disconnected state, the node device obtains the address information of the superior node by reading a preset adjacent information table.
In step S102, heartbeat request information is transmitted to address information of the upper node.
Specifically, the current node sends heartbeat request information to the superior node, and the heartbeat request information can be used for judging whether the connection with the superior node is normal or not.
In step S103, if heartbeat response information based on the heartbeat request information is received, cache information is sent to the upper node, where the cache information includes data information within a preset time period.
Specifically, when receiving heartbeat response information based on the heartbeat request information replied by the upper node, the connection with the upper node is normal at this time, and at this time, the cache information is sent to the upper node. When the node is in a disconnection state at a certain time period, the data information in the time period is stored as the cache information and is sent again after the connection is established, so that the reliability of the data can be enhanced.
In step S104, a user subscription information request is sent to the upper node.
Specifically, if a connection request of the cross-region terminal is received or a preset synchronization time point is reached, the current node may send a user subscription information request to the upper node.
In step S105, the user subscription data information belonging to the current node and sent by the upper node is received, and data updating is performed according to the user subscription data information of the current node.
Specifically, after receiving the user subscription information request, the superior node issues user subscription data information belonging to the current node, and the current node receives the user subscription data information and performs data update according to the user subscription data information of the current node. Wherein, the data updating comprises the data updating of covering the user subscription data information to the local and triggering the memory and the network management.
As can be seen from the above, in the synchronization method in the embodiment of the present invention, when the current node starts or re-accesses the network, the heartbeat request information is sent to the upper node, and when the heartbeat reply information is received, the cache information is sent to the upper node, so that it can be ensured that the information of the current node is synchronized to the upper node in time; meanwhile, the information of the superior node can be ensured to be synchronized to the current node by receiving the user subscription data information which is sent by the superior node and belongs to the current node and updating the data according to the user subscription data information; by synchronizing the data information among the nodes in time, the consistency of the data of the nodes in the network can be ensured, the problem of cross-region roaming in a miniaturized LTE network is effectively solved, the network erection cost is saved, and the network resources are saved.
Fig. 4 is a flowchart of a synchronization method according to a second embodiment of the present invention. Compared with the first embodiment shown in fig. 3, in this embodiment, the current node may also store information of other nodes by establishing a cache table, so as to facilitate network maintenance. The synchronization method comprises steps S201-S212.
In step S201, an adjacency information table preset by the current node is read, where the adjacency information table includes address information of a higher node.
In step S202, a cache table is established.
Specifically, in this embodiment, the node device establishes a cache table, where the cache table is used to store information of other node devices, where the cache table may be used not only to store information of a higher node but also to store information of a lower node when a heartbeat request of the lower node is received.
In step S203, information of the upper node is stored in the cache table, where the information of the upper node includes address information and status information of the upper node.
Specifically, information of a superior node is stored in a cache table, where the information includes address information and state information of the superior node. Optionally, the information may further include an IMSI (international mobile Subscriber identity) Number segment of the node and a counter. The initial value of the counter is 0, and the counter is used for counting to judge the connection state of the corresponding node. The status information includes a fault status and a normal status. Optionally, the initial state of the state information of the upper node is a fault state.
In step S204, heartbeat request information is sent to the address information of the upper node.
In step S205, it is determined whether heartbeat response information is received.
Specifically, it is determined whether heartbeat response information based on the heartbeat request information is received, and if so, the process proceeds to step S206; if not, the process proceeds to step S210.
In step S206, if heartbeat response information based on the heartbeat request information is received, the value of the counter is reset to 0, and the state information of the upper node is set to a normal state.
Specifically, when receiving the heartbeat response information, it indicates that the connection with the upper node is normal, and at this time, the state information of the upper node is set to be in a normal state.
In step S207, cache information is sent to the superordinate node, where the cache information includes data information within a preset time period.
In step S208, a user subscription information request is sent to the upper node.
In step S209, the user subscription data information belonging to the current node and sent by the upper node is received, and data updating is performed according to the user subscription data information of the current node.
In step S210, if the heartbeat response information based on the heartbeat request information is not received, the value of the counter is incremented by 1.
Specifically, if the heartbeat response message is not received, the value of the counter is incremented by 1, and the process goes to step S204 to send the heartbeat response message again. Optionally, a timer may be further set, and after the timer finishes timing, the step S204 is executed to perform the sending, where the time of the timer may be preset.
In step S211, it is determined whether the value of the counter is 5.
Specifically, in this step, before sending the heartbeat response information again, it is further necessary to determine whether the current counter value is 5. If the value of the counter is 5, it indicates that 5 heartbeat requests have been sent, and no heartbeat response has been received, and at this time, it can be considered that the connection with the upper node has been broken, and at this time, the process proceeds to step S212; if the value of the counter is not 5, the process proceeds to step S204, where it is transmitted.
It is understood that the step S211 is an optional step, that is, after the heartbeat response message is not received in the step S210, the step S204 may be directly entered for repeated transmission. The counter determination criterion value 5 in this step may also be other values, which is not limited in the embodiment of the present invention.
In step S212, the link disconnection between the current node and the upper node is confirmed.
Specifically, when the counter is 5, the link disconnection between the current node and the upper node is confirmed. At this time, it may be considered that a fault exists between the current node and the upper node, and related personnel may be notified to perform maintenance by sending a notification message.
As can be seen from the above, in the synchronization method in the embodiment of the present invention, when the current node starts or re-accesses the network, the heartbeat request information is sent to the upper node, and when the heartbeat reply information is received, the cache information is sent to the upper node, so that it can be ensured that the information of the current node is synchronized to the upper node in time; meanwhile, the information of the superior node can be ensured to be synchronized to the current node by receiving the user subscription data information which is sent by the superior node and belongs to the current node and updating the data according to the user subscription data information; in addition, the information of the corresponding nodes is stored by establishing the cache table, so that the subsequent management and maintenance are facilitated.

In this embodiment, the synchronization method is applied to a node device, which may be an EPC device, and network elements such as an MME (mobility Management Entity), an SGW (Serving GateWay), a PGW (Packet data network GateWay), and an HSS (Home Subscriber Server) are integrated on the node device, and the network elements are presented in a form of being concentrated on one Server or in one small-sized machine frame device. The synchronization method in this embodiment is applied to a node device receiving information of a subordinate node and performing information synchronization with the subordinate node. For example, the method may be applied to the node 100 receiving the information of the node 201, and may also be applied to the node 201 receiving the information of the node 300. The synchronization method comprises steps S301-S303.
In step S301, if heartbeat request information sent by a lower node is received, heartbeat response information is sent according to the heartbeat request information.
Specifically, when the current node device receives heartbeat request information sent by a lower node, the current node device replies heartbeat response information according to the heartbeat request information.
In step S302, cache information sent by the subordinate node is received, where the cache information includes user subscription data information within a preset time period.
Specifically, the lower node sends the cache information after receiving the heartbeat response information. At this time, the node device receives the cache information sent by the lower node. The cache information comprises user subscription data information in a preset time period.
In step S303, if a user subscription information request sent by the subordinate node is received, user subscription data information belonging to the subordinate node is sent to the subordinate node, so that the subordinate node performs data update according to the user subscription data information.
Specifically, if a user subscription information request sent by a subordinate node is received, user subscription data information belonging to the subordinate node is searched in a stored database, and the user subscription data information is sent to the subordinate node. And the subordinate node performs data updating according to the user subscription data information.
As can be seen from the above, in the synchronization method in the embodiment of the present invention, when a heartbeat request sent by a lower node is received, a heartbeat response message is replied, a cache message sent by the lower node is received, and a user subscription data message belonging to the lower node is issued according to the request of the lower node, so that information synchronization with the lower node can be completed, consistency of data of each node in a network is ensured, a problem of cross-region roaming in a small LTE network is effectively solved, network construction cost is saved, and network resources are saved.

Compared with the first embodiment shown in fig. 5, in this embodiment, the current node may also store information of other nodes by establishing a cache table, so as to facilitate network maintenance. The synchronization method comprises steps S401-S406.
In step S401, if heartbeat request information sent by a lower node is received, heartbeat response information is sent according to the heartbeat request information.
In step S402, a cache table is established.
Specifically, the node device establishes a cache table, where the cache table is used to store information of other node devices, and the cache table may be used to store information of a subordinate node when receiving a heartbeat request of the subordinate node, and may also be used to store information of a higher node.
In step S403, storing information of the lower node in the cache table, where the information of the lower node includes: address information and status information of the subordinate node.
Specifically, after receiving heartbeat request information of a subordinate node, the information of the subordinate node is stored in the cache table, where the information of the subordinate node includes: the address information and the state information of the lower node, optionally, the information may further include an IMSI (International Mobile subscriber identity) Number segment of the node. Wherein the status information includes a normal status and a fault status.
In step S404, the state information of the lower node is set to a normal state.
Specifically, since the heartbeat request information of the lower node is received, the heartbeat request information of the lower node is set to be in a normal state in the cache table.
In step S405, cache information sent by the subordinate node is received, where the cache information includes user subscription data information within a preset time period.
In step S406, if a user subscription information request sent by the subordinate node is received, user subscription data information belonging to the subordinate node is sent to the subordinate node, so that the subordinate node performs data update according to the user subscription data information.
As can be seen from the above, the synchronization method in the embodiment of the present invention replies heartbeat response information when receiving a heartbeat request sent by a subordinate node, receives cache information sent by the subordinate node, and issues user subscription data information belonging to the subordinate node according to the request of the subordinate node, so that information synchronization with the subordinate node can be completed, and consistency of data of each node in a network is ensured.
