EDSG Service Activation and Deactivation
EDSG services can be activated by binding a service policy group to a domain or through RADIUS or Diameter.
RADIUS supports both static and dynamic activation. Static activation means that an EDSG service policy is delivered during user login through user authentication response packets carrying the HW-Account-Info(26-184) or HW-Policy-Name(26-95) attribute. Dynamic activation means that the EDSG service is activated during user login through dynamic authorization messages, such as the CoA messages carrying the HW-Command-Mode(26-34) or HW-Policy-Name(26-95) attribute.
- The HW-Account-Info(26-184) attribute is in the format of A<service-name>[;authen-name;password] if services automatically take effect after delivery and in the format of N<service-name> if services do not automatically take effect after delivery.
- The HW-Policy-Name(26-95) attribute is in the format of <service-name>[;authen-name;password] after delivery. You can perform configuration to allow this attribute to support the EDSG service policy. This attribute can carry multiple EDSG service names.
The HW-Command-Mode(26-34) attribute is used to activate the EDSG service when the first byte is 0x0B followed by a service name.
Diameter supports service activation through CCR-I messages during user login as well as dynamic service activation through RAR messages after users go online.
The EDSG service activation process is as follows:
- (Optional) Perform service authentication.
- (Optional) Download the content of a service policy template.
- Install service forwarding entries.
- After service installation is completed, trigger to start service accounting (You can set the accounting mode to non-accounting.)
The EDSG service deactivation process is as follows:
- Service deactivation when a user goes offline: All EDSG services of a user are automatically stopped when the user goes offline.
- Dynamic service deactivation: During user login, protocols (such as CoA and DM) are used to delete the user's EDSG service.
- Service deactivation after service quotas are exhausted: The service is automatically deleted by default after the duration or volume quota of the service is exhausted.
- Service deactivation after replacement: The original EDSG service in a service group is automatically deactivated after a new EDSG service in the service group is activated. (For details, see EDSG Service Replacement and Restoration.)
The EDSG service deactivation process is as follows:
- Delete service forwarding entries.
- After service forwarding entries are deleted, trigger accounting-stop requests (The accounting mode can be set to non-accounting.)
- Uninstall all contents of the service.
