If the subscription information includes that the device user has contracted with the DC or is authorized to use DC capacity, DC services, or DC operations, then after receiving the first message from the first device, the first network device determines, based on the contract information, that the device user of the first device has contracted with the DC or is authorized to use DC capacity, DC services, or DC operations, thereby indicating that the subscription conditions are met. If the subscription information includes the identifier of the first device and / or the identifier of the second device, the first network device, after receiving the first message from the first device, determines whether the identifier of the first device matches the identifier of the first device in the subscription information, or whether the identifier of the other device (the identifier of the second device) that the first message requests matches the identifier of the second device in the subscription information, thereby indicating that the subscription conditions are met.

[0135] For example, if the configuration information includes at least some of the information of the first DC information, for instance, if a designated DC has been set up locally or the operator has authorized the establishment of a designated DC, then when the first DC information includes the designated DC, the system determines that the subscription conditions are met and sends the second message to the first network function. If the configuration information includes whether a device user has contracted with a DC or is authorized to use DC capacity, DC services, or DC operations, then after receiving the first message from the first device, the first network device determines, based on the contract information, that the device user of the first device has contracted with a DC or is authorized to use DC capacity, DC services, or DC operations, thereby indicating a match with the configuration information. If the configuration information includes the identifier of the first device and / or the identifier of the second device, then after receiving the first message from the first device, the first network device determines that the identifier of the first device matches the identifier of the first device in the configuration information, or that the identifier of the other device that the first message is trying to call (the identifier of the second device) matches the identifier of the second device in the configuration information, thereby indicating a match with the configuration information.

If network 1 obtains user contract information as needed, network 1 DC messages must include user information (e.g., identifier of device 1) so that network 1 can obtain user contract information corresponding to device 1. Capability and / or service information of a counterpart device (e.g., device 2) and / or a counterpart network (e.g., network 2) can be obtained based on a reporting or subscription mechanism (establishing reporting of NNI information).
