It should be understood that the above-mentioned service network elements are only exemplary, and the present invention does not impose any restrictions on the service network elements.

S120: Deploy backup service network elements corresponding to multiple service network elements to different communication service areas.

In one embodiment of the present invention, the core network includes multiple communication service areas, and each communication service area includes multiple service network elements. A certain communication service area in the core network is used as a target communication service area, and backup service network elements corresponding to multiple service network elements included in the target communication service area are respectively deployed to multiple other different communication service areas.

As an example, if the core network includes: A communication service area, B communication service area and C communication service area.

First, take communication service area A as the target communication service area, and assume that the service network elements included in communication service area A are: IMS network element and EPC network element. At this time, the backup service network elements corresponding to the A communication service area are: IMS backup service network element and EPC backup service network element. At this time, the optional deployment methods for backup service network elements in communication service area A are as follows:

The first deployment method is: deploy the IMS backup service network elements of the A communication service area in the B communication service area, and deploy the EPC backup service network elements of the A communication service area in the C communication service area.

The second deployment method is: deploy the IMS backup service network elements of the A communication service area in the C communication service area, and deploy the EPC backup service network elements of the A communication service area in the B communication service area.

Secondly, after deploying communication service area A, you can continue to use communication service area B as the target communication service area. It is assumed that the service network elements included in the B communication service area are: IMS network element and EPC network element. At this time, the backup service network elements corresponding to the B communication service area are: IMS backup service network element and EPC backup service network element. At this time, the optional deployment methods for backup service network elements in B communication service area are as follows:

The first deployment method: deploy the IMS backup service network elements of B communication service area in A communication service area, and deploy the EPC backup service network elements of B communication service area in C communication service area.

The second deployment method is: deploy the IMS backup service network elements of B communication service area in C communication service area, and deploy the EPC backup service network elements of B communication service area in A communication service area.

Finally, after deploying the B communication service area, you can continue to use the C communication service area as the target communication service area. It is assumed that the service network elements included in the C communication service area are: IMS network element and EPC network element. At this time, the backup service network elements corresponding to the C communication service area are: IMS backup service network element and EPC backup service network element. At this time, the optional deployment methods for backup service network elements in C communication service area are as follows:

The first deployment method: deploy the IMS backup service network elements of C communication service area in A communication service area, and deploy the EPC backup service network elements of C communication service area in B communication service area.

At this time, the service capacity of the IMS backup service network element is 200 users, and the service capacity of the EPC backup service network element is 300 users. Since the IMS backup service network element and the EPC backup service network element share resources, And the shared resource capacity should be the maximum service capacity among the services carried by the IMS backup service network element and the EPC backup service network element. Therefore, at this time, the shared resource capacity of the IMS backup service network element and the EPC backup service network element should be 300 user services.

S140. If the target communication service area fails, allocate the services carried by the target communication service area to the communication service area deployed with backup service network elements, so that the communication service area deployed with backup service network elements can bear the services carried by the target communication service area. Business.

In an embodiment of the present invention, if the target communication service area fails, the service network elements in the target communication service area cannot continue to carry corresponding services.

The business carried by the area.

In the embodiment of the present invention, backup service network elements corresponding to multiple service network elements in the same communication service area are respectively deployed to different communication service areas, and multiple backup service network elements in each communication service area Shared resources can improve the utilization of resource capacity in the communication service area.

In another embodiment of the present invention, the business disaster recovery method further includes:

According to the priority and/or service bearing weight of each communication service area, services are allocated to each communication service area, so that each communication service area carries its assigned services.

When allocating services to each communication service area, the services will be allocated to communication service areas with high priority first, and based on the service bearing weight, it will be decided to allocate corresponding capacity services to each communication service area.

As an example, if services are allocated to each communication service area based on priority, then when the priority of A communication service area is higher than that of B communication service area, services will be allocated to A communication service area first. When A communication service area carries When the business reaches the maximum business volume it carries, the business will be allocated to the B communication service area.

As an example, if services are allocated to each communication service area based on service bearer weights, when the service bearer weight ratio between A communication service area and B communication service area is 1:4, 1/5 of the services will be allocated To the A communication service area, allocate 4/5 of the business to the B communication service area. Assume that there are services for 200 users, then allocate the services of 40 users to the A communication service area, and allocate the services of the remaining 160 users to the B communication service area.

As an example, if services are allocated based on priority and service bearer weight, then when the priority of A communication service area is higher than that of B communication service area, and the business bearer weight ratio between A communication service area and B communication service area is When 4:1, 4/5 of the business will be allocated to the A communication service area first, and then 1/5 of the business will be allocated to the B communication service area.

Assume that the service capacity of the EPC backup service network element in Region A is 100 users, and the service capacity of the SMSC backup service network element in Region C is 50 users. Since the EPC backup service network element in Region A shares resources with the SMSC backup service network element in Region C, and the shared resource capacity is the services carried by the EPC backup service network element in Region A and the SMSC backup service network element in Region C Therefore, the backup service network element capacity of area B should be the service of 100 users.

Among them, the service capacity of SMSC network element and EPC network element is 100 users. Moreover, Region C includes: the IMS backup service network element of Region A and the EPC backup service network element of Region B. Assume that the service capacity of the IMS backup service network element in Region A is 50 users, and the service capacity of the EPC backup service network element in Region B is 100 users. Since the IMS backup service network element of Region A and the EPC backup service network element of Region B share resources, and the shared resource capacity is the services carried by the IMS backup service network element of Region A and the EPC backup service network element of Region B, Therefore, the backup service network element capacity of Region C should be the service of 100 users. The business carrying capacity of Region C is 200 user services.

In summary, it can be obtained that the total service carrying capacity of the three regions is 600 users, and the total service capacity of the three regions is 900 users. Then, for area A, area B and area C, the resource capacity utilization rate is 600/900, which is higher than the 50% resource capacity utilization rate of the communication service area in the prior art.
