Offload processing method, control unit, and system

A controller comprising at least one processor, a non-transitory computer readable memory, and a network interface, wherein the memory stores an execution instruction that when executed by the processor cause the processor to communicate with the network interface, and the network interface to communicate with a first-standard network and a second-standard network, wherein the at least one processor is configured to

• acquire, after a user equipment (UE) accesses the first-standard network, first resource status information describing resources of the first-standard network for providing data processing services and second resource status information describing resources of two or more second-standard network overlapping service areas;
• determine a residual capacity of a serving cell of the first-standard network for providing data processing services according to the first resource status information and residual capacities of overlapping serving cells of the two or more second-standard network for providing data processing services according to the second resource status information;
• acquiring service type information of a data processing service required by the UE, wherein the service type information includes information of different types of possible services required by the UE, including a browsing service;
• selecting one of the second-standard networks based on the acquired service type information;
• and
• offloading, by the controller, traffic of the UE to the selected one of the second-standard networks when (a) the residual capacity of the selected second-standard network is determined from the second resource status information to be greater than the residual capacity of the first-standard network and (b) the residual capacity of the first-standard network does not meet performance requirements for the data processing service required by the UE that is identified by the acquired service type information.

A non-transitory computer readable medium, comprising a computer execution instruction, wherein the computer execution instruction causes a controller to execute the following:

• after a user equipment (UE) accesses a first-standard network, acquiring, first resource status information describing resources of the first-standard network for providing data processing services and second resource status information describing resources of two or more second-standard networks for providing data processing services, where the first and second-standard networks have overlapping service areas;
• determine a residual capacity of a serving cell of the first-standard network for providing data processing services according to the first resource status information and residual capacities of overlapping serving cells of the two or more second-standard network for providing data processing services according to the second resource status information;
• acquiring service type information of a data processing service required by the UE, wherein the service type information includes information of different types of possible services required by the UE, including a browsing service;
• selecting one of the second-standard networks based on the acquired service type information;
• and
• offloading traffic of the UE to the selected one of the second-standard networks when (a) the residual capacity of the selected second-standard network is determined from the second resource status information to be greater than the residual capacity of the first-standard network and (b) the residual capacity of the first-standard network does not meet performance requirements for the data processing service required by the UE that is identified by the acquired service type information.

A system comprising a first controller having at least one processor, a non-transitory memory, and a network interface, wherein the memory stores an execution instruction that when executed by the processor configures the processor to:

• acquire, after a user equipment (UE) accesses a first-standard network, first resource status information describing resources of the first-standard network for providing data processing services and second resource status information describing resources of two or more second-standard network for providing data processing services overlapping service areas;
• determine a residual capacity of a serving call of the first-standard network for providing data processing services according to the first resource status information and residual capacities of overlapping serving cells of the two or more second-standard network for providing data processing services according to the second resource status information;
• acquiring service type information of a data processing service required by the UE, wherein the service type information includes information of different types of possible services required by the UE, including a browsing service;
• selecting one of the second-standard networks based on the acquired service type information;
• and
• offloading traffic of the UE to the selected one of the second-standard networks when (a) the residual capacity of the selected second-standard network is determined from the second resource status information to be greater than the residual capacity of the first-standard network and (b) the residual capacity of the first-standard network does not meet performance requirements for the data processing service required by the UE that is identified by the acquired service type information;
• other controllers of other networks, wherein each other controller communicates with the first controller through the network interface.
