3G/4G Policy Session APIs
The SubMan APIs include session query, session validation, and session delete APIs for charging and policy sessions.
Query Sessions
- For a policy session, the
information returned in the MtxPolicySessionInfo MDC includes the following:
- SessionId
- UpdateTime
- SessionStartTime
- SourceHost
- SourceRealm
- SessionType (1 = Sy, 2 = Gx,)
- PolicyProfileName
- Any private, session MDC fields (MtxChargingSessionExtension and MtxPolicySessionExtension)
Validate Sessions
The MtxRequestDeviceValidateSession SubMan API validates sessions.
When a session is validated, a Gy RAR, Sy SNR, or Gx RAR message is sent. The
API input can include the
SessionId
and the
SessionType
.
- Gy = 1
- Sy = 2
- Gx = 3
If neither the
SessionId
or the
SessionType
is specified, all open sessions for the
specified device are validated. If the device has no open sessions, no errors
are returned. If a
SessionId
is specified, only the specified session is
validated. If the specified session is not found, an error is returned. If a
SessionId
is not specified, but a
SessionType
is specified, only sessions of the
specified type are validated. If the device does not have sessions of the
specified type, no errors are returned.
If the session to be validated is a charging session, a Gy RAR message is sent for every context in the session.
If the session to be validated is an Sy policy session, an Sy SNR message is sent regardless of whether the applicable Sy policy counters have changed.
For more information about policy and charging APIs, see Subscriber Management (SubMan) API.
Delete Sessions
Specify the individual session IDs to delete by using the MtxRequestDeviceDeleteSession API. If
the SessionIdList
is not populated, all sessions of the type
specified by SessionType
are deleted. If neither of these
parameters are populated, all sessions for this device will be deleted.
- Gy = 1
- Sy = 2
- Gx = 3
