AI Technical Summary
In existing technologies, the success rate of disaster recovery and emergency switching methods is low, especially when all devices in the same resource pool fail, existing technologies cannot effectively achieve disaster recovery and emergency switching.
Disaster recovery and emergency handover are performed on the base station side by switching the base station to different equipment connections on the core network side through cross-resource pools. Specifically, this includes modifying communication parameters and sending gateway parsing data to ensure that the base station connects to the new equipment and avoids affecting the normal operating equipment on the core network side.
It improves the success rate of disaster recovery and emergency handover, ensuring that base stations can still connect normally to core network side equipment when all equipment in the same resource pool fails, and reduces the impact on core network connection equipment.

Therefore, when facing a failure of all equipment in the same resource pool, compared with handover within the same resource pool, it can still ensure that the base station can normally connect to the core network equipment, realize disaster recovery emergency, and make the disaster recovery emergency handover success rate higher.

[0044] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.
[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.
[0046] Disaster recovery and emergency response sometimes face the following scenario: all devices in the same resource pool fail. Due to the limitations of the existing device resource pool configuration during disaster recovery, existing disaster recovery and emergency switching methods will fail in this scenario, resulting in a low success rate.
[0047] To address the problems of existing technologies, this application provides a disaster recovery and emergency handover method, apparatus, device, and storage medium. In the event of a failure of the first device on the core network side currently connected to the base station, this application performs a disaster recovery and emergency handover on the base station side. Compared to performing a disaster recovery and emergency handover on the core network side, where a failure on the core network affects the entire system, impacting normally functioning equipment connected to the core network, the operation on the base station side only affects the base station itself. Specifically, this application switches the base station to a second device on the core network side. The first and second devices belong to different resource pools; that is, this application actually employs a cross-resource pool base station connection to core network side equipment handover. Therefore, even when all devices in the same resource pool fail, compared to handover within the same resource pool, it still ensures that the base station can normally connect to the core network equipment, achieving disaster recovery and emergency handover with a higher success rate. The disaster recovery and emergency handover method provided in this application will be described below.
[0048] Figure 1 This illustration shows a flowchart of a disaster recovery and emergency handover method provided in one embodiment of this application. The method is applied to a base station, such as... Figure 1 As shown, the method may include the following steps:
[0049] S110: When the first device on the core network side currently connected to the base station fails, the base station will be switched to the second device on the core network side for connection.
[0050] The first device and the second device belong to different resource pools.
[0051] In the current network, the provincial backbone packet transport network PTN layer has fully connected the transmission between equipment rooms, enabling cross-resource pool (POOL) disaster recovery. Before disaster recovery switching, the core network's ability to count users based on tracking area codes (TACs) is used to assess the number of users that need to be migrated during cross-pool switchover. Then, the service load of each POOL is assessed, such as: number of users... tens of thousands, capacity utilization...%, peak traffic... Gbps, bandwidth utilization...%. Based on the service load, the current POOL's capacity to support disaster recovery switching can be evaluated. A switching mapping relationship between the first and second devices during disaster recovery switching is constructed based on the disaster recovery switching capacity of each POOL. Taking Wuhan as an example, the service load of different POOLs is shown in Table 1:
[0052] Table 1
[0053] POOL name Device operator Carrying business city POOL3 Operator A Wuhan (Wuchang), Huangshi, Ezhou POOL4 Operator A Wuhan (Wuchang), Xianning POOL7 Operator B Wuhan (Hanyang), Xiaogan POOL8 Operator C Wuhan (Hankou), Huanggang
[0054] As can be seen from Table 1, if operator A's equipment experiences a complete outage for some reason, disaster recovery from pool POOL3 to pool POOL4 is meaningless. Therefore, considering factors such as different operators and geographical location, the final determined disaster recovery handover mapping relationship between the first and second devices can be:
[0055] 1) When the first device in operator A pool POOL3 fails, disaster recovery is performed on the second device in operator C pool POOL8;
[0056] 2) When the first device in operator A pool POOL4 fails, disaster recovery is performed on the second device in operator B pool POOL7;
[0057] 3) When the first device in operator C pool POOL8 fails, disaster recovery is performed on the second device in operator B pool POOL7;
[0058] 4) When the first device in operator B pool POOL7 fails, disaster recovery is performed on the second device in operator C pool POOL8.
[0059] In this embodiment, when the first device on the core network side currently connected to the base station fails, a disaster recovery handover is performed on the base station side. Compared to a disaster recovery handover on the core network side, where a failure on the core network affects the entire system, this approach only impacts the base station itself. Specifically, this embodiment switches the base station to a second device on the core network side. The first and second devices belong to different resource pools. In other words, this embodiment actually uses a cross-resource pool base station handover to the core network side device. Therefore, when all devices in the same resource pool fail, compared to handover within the same resource pool, it still ensures that the base station can normally connect to the core network device, achieving disaster recovery and resulting in a higher success rate for disaster recovery handover.
[0060] In one embodiment, S110 may include:
[0061] When the first device on the core network side currently connected to multiple base stations fails, the geographical area to which the multiple base stations belong is determined; according to the preset correspondence between geographical areas and handover order, the multiple base stations are sequentially switched to the second device on the core network side for connection.
[0062] Considering the limited capacity of the POOL, there may be situations where the disaster recovery POOL cannot support all the base stations that need to be switched. Therefore, according to the preset correspondence between geographical areas and switching order, multiple base stations are switched to the second device connection on the core network side in sequence, thereby ensuring that base stations in important geographical areas can be switched first. The preset geographical areas and switching order are that important geographical areas come first. Important geographical areas may include: key business districts, transportation hubs, and other corresponding geographical areas.
[0063] In one embodiment, S110 may include:
[0064] S1101, when the first device on the core network side currently connected to the base station fails, the communication parameters of the first device currently configured by the base station are modified to the communication parameters of the second device.
[0065] S1102, Connect the base station to the second device according to the communication parameters of the second device.
[0066] The communication parameters can include the Tracking Area Code (TAC) and the S1 interface IP address, or the Tracking Area Identifier (TAI) and the S1 interface IP address. After joint evaluation with wireless professionals, it was found that all modifications to the base station configuration on the wireless side are issued through the OMC. Modifications to the S1 interface IP address and TAC configuration can be done through batch command issuance. The above operations can be completed in just one minute, and the disaster recovery switchover time is extremely short.
[0067] In one embodiment, when the first device on the core network side currently connected to the base station fails, the S1 interface IP address of the first device currently configured by the base station can be changed to the S1 interface IP address of the second device. However, this will cause the second device to generate a large amount of TAC data. According to wireless testing and evaluation, it takes more than one hour, and the disaster recovery switching time is relatively long.
[0068] In one embodiment, the first device belongs to a first Mobility Management Node Function (MLM) resource pool, and the second device belongs to a second MLM resource pool; or, the first device belongs to a first SAE-GW resource pool, and the second device belongs to a second SAE-GW resource pool. S1101 may include:
[0069] Modify the current tracking area code and S1 interface IP address of the base station to the tracking area code and S1 interface IP address of the second device.
[0070] In one embodiment, the first device belongs to the SAE-GW resource pool, and the second device belongs to the Mobility Management Node Function resource pool. S1101 may include:
[0071] Send the PDN gateway resolution data and service gateway resolution data of the first device to the second device, so that the second device can connect to the base station based on the PDN gateway resolution data and service gateway resolution data of the first device; modify the tracking area code and S1 interface IP address currently configured by the base station to the tracking area code and S1 interface IP address of the second device.
[0072] In the current network, the Serving Gateway (SGW) and the PDN Gateway (PGW) are co-located and referred to as SAE-GW. Currently, the routing from the Mobility Management Node (MME) network element to the SAE-GW network element is interconnected through a dedicated Gn interconnection link. The transmission between different equipment rooms is fully connected, and cross-pool disaster recovery is possible. However, due to the configuration differences between the SAE-GW resource pool and the MME resource pool, directly modifying the current tracking area code and S1 interface IP address of the base station to the tracking area code and S1 interface IP address of the second device is insufficient to connect the base station and the second device based solely on the communication parameters of the second device. Gateway configuration for the second device is required first. Therefore, when the base station performs disaster recovery from the first device in the SAE-GW resource pool to the second device in the MME resource pool, it needs to send the PDN Gateway (PDGWay, PGW) resolution data and Serving Gateway (SGW) resolution data of the first device to the second device. This allows the second device to perform gateway configuration based on the PDN Gateway resolution data and Serving Gateway resolution data of the first device. Then, by modifying the current tracking area code and S1 interface IP address of the base station to the tracking area code and S1 interface IP address of the second device, the disaster recovery handover can be successfully ensured.
[0073] In one embodiment, the first device and the second device belong to different operators.
[0074] As can be seen from Table 1, if the operator equipment of operator A experiences a complete shutdown for some reason, disaster recovery from operator A's POOL3 to operator A's POOL4 is meaningless. Therefore, the first and second equipment in this application belong to different operators, thus avoiding disaster recovery failure.
[0075] In this embodiment, when the first device on the core network side currently connected to the base station fails, a disaster recovery handover is performed on the base station side. Compared to a disaster recovery handover on the core network side, where a failure on the core network affects the entire system, this approach only impacts the base station itself. Specifically, this embodiment switches the base station to a second device on the core network side. The first and second devices belong to different resource pools. In other words, this embodiment actually uses a cross-resource pool base station handover to the core network side device. Therefore, when all devices in the same resource pool fail, compared to handover within the same resource pool, it still ensures that the base station can normally connect to the core network device, achieving disaster recovery and resulting in a higher success rate for disaster recovery handover.
