Session Records and Usage⚓︎

Session history and usage records in xControl are complete, accurate to the byte, attributed to the right Site and System, produced for sessions that end abnormally, and delivered even when the site was out of contact while the session ran.

EXP-REC-001 — Session record completeness⚓︎

Attribute	Value
Status	Accepted
Category	Functional
Components	xControl, xCore
Applies to	4G, 5G · Local radio, Public radio · Single node, HA cluster, Geo-redundant
Duration	About 20 min
Prerequisite procedures	EXP-SES-001 — UE-initiated attach EXP-SES-002 — UE-initiated detach
Included in	Installation and Upgrade Verification

Objective. The record of a completed session carries every field an MNO needs to account for it, and the values agree with the signalling capture of the same session.

Preconditions

Tooling and access
- Log in to xControl with an account that holds the ADMIN role.
- An API token for the Customer.
Procedures executed first
- EXP-SES-001 — UE-initiated attach
- EXP-SES-002 — UE-initiated detach

Procedure

#	Where	Action	Expected result
1	—	Execute EXP-SES-001 — UE-initiated attach as a prerequisite procedure.	As defined in EXP-SES-001.
2	—	Execute EXP-SES-002 — UE-initiated detach as a prerequisite procedure.	As defined in EXP-SES-002.
3	xControl	Open the Mobile Asset's Event Log, select Session, and use the Column Chooser to show every column.	The closed session shows the Site and System names, the IMSI and IMEI, start and end time, the IP address and state Closed.
4	xControl API	Retrieve the session report for the IMSI through the API.	The record carries the IMEI, start and stop time, MCC, MNC, tracking area, radio identifier, bearer identifier, IP address, APN name, radio access technology, state, cause code, upload and download bytes, and links to the Site, System and subscriber.
5	Capture	Compare the record with the capture of EXP-SES-001 and EXP-SES-002.	The IP address equals the PDN or PDU address assigned; MCC, MNC and tracking area equal the tracking area identity in the attach; the radio identifier equals the cell identity in the attach; the start time is within one minute of the Attach Complete and the end time within one minute of the detach.

Pass criteria

Every field listed is present and consistent with the capture.
Start and end times are within 5 seconds of the corresponding signalling messages.

Evidence collected: xControl screenshot; 3GPP signalling capture (pcap).

EXP-REC-002 — Usage accounting accuracy⚓︎

Attribute	Value
Status	Accepted
Category	Functional
Components	xControl, xCore
Applies to	4G, 5G · Local radio, Public radio · Single node, HA cluster, Geo-redundant
Duration	About 30 min
Prerequisite procedures	EXP-SES-001 — UE-initiated attach EXP-SES-002 — UE-initiated detach

Objective. The upload and download byte counts recorded for a session equal the bytes the UE actually sent and received, as counted on the enterprise side of the user plane.

Preconditions

Device
- Background traffic on the UE is disabled (see Devices and SIMs in Test environment and tooling).
Tooling and access
- A host on the enterprise LAN serving a file of known size over HTTP and running an iperf3 server.
- A capture on the enterprise side of the user plane (SGi / N6) filtered to the UE's address.
- Log in to xControl with an account that holds the ADMIN role.
Procedures executed first
- EXP-SES-001 — UE-initiated attach
- EXP-SES-002 — UE-initiated detach

Procedure

#	Where	Action	Expected result
1	—	Execute EXP-SES-001 — UE-initiated attach as a prerequisite procedure.	As defined in EXP-SES-001.
2	Capture	Start the SGi / N6 capture filtered to the UE's address.	The capture is running.
3	UE	Download the known-size file from the LAN host, then upload a fixed amount with iperf3 (for example 20 MB).	Both transfers complete.
4	—	Execute EXP-SES-002 — UE-initiated detach as a prerequisite procedure.	As defined in EXP-SES-002.
5	Capture	Stop the capture and read the byte totals of the UE's conversation in each direction (IP layer).	Upload and download totals are recorded.
6	xControl	Open the closed session's record.	Upload and download bytes are shown.
7	Tester	Compare the record with the capture totals.	The record equals the capture totals.

Pass criteria

Recorded upload and download bytes equal the IP-layer bytes counted on the enterprise side of the user plane for the session.

Evidence collected: 3GPP signalling capture (pcap); xControl screenshot.

EXP-REC-003 — Record of a session that ended abnormally⚓︎

Attribute	Value
Status	Accepted
Category	Functional
Components	xControl, xCore
Applies to	4G, 5G · Local radio · Single node, HA cluster, Geo-redundant
Duration	About 30 min
Prerequisite procedures	EXP-SES-010 — Implicit detach after loss of the device

Objective. A session that ends without a detach, because the device disappeared, is closed with a cause that says so, and its byte counts reflect the traffic exchanged before the loss.

Preconditions

Tooling and access
- Log in to xControl with an account that holds the ADMIN role.
Procedures executed first
- EXP-SES-010 — Implicit detach after loss of the device

Procedure

#	Where	Action	Expected result
1	UE	Before the loss step of EXP-SES-010, download a known-size file from the LAN host.	The transfer completes.
2	—	Execute EXP-SES-010 — Implicit detach after loss of the device as a prerequisite procedure.	As defined in EXP-SES-010.
3	xControl	Open the closed session's record.	The end time corresponds to the implicit detach, the cause code differs from a normal detach, and the download bytes cover the file transferred before the loss.

Pass criteria

The record is closed with a cause that identifies the abnormal end.
The byte counts include the traffic exchanged before the loss.

Evidence collected: xControl screenshot.

2	—	Execute EXP-SES-001 — UE-initiated attach as a prerequisite procedure.	As defined in EXP-SES-001.
3	UE	Download the known-size file, then detach (EXP-SES-002).	The session completes while the Site is out of contact.
4	xControl	Open the Mobile Asset's Event Log.	The session run during the outage is not yet visible.
5	Infrastructure	Remove the block. Note the time.	The Site returns to online.

Attribute	Value
Status	Accepted
Category	Functional
Components	xControl
Applies to	4G, 5G · Local radio, Public radio · Single node, HA cluster, Geo-redundant
Duration	About 20 min
Prerequisite procedures	EXP-REC-001 — Session record completeness

Objective. Detailed and summary usage reports generated in xControl contain the sessions of the period, their totals agree with the session records, and a configured SFTP delivery receives the file.

Preconditions

Platform
- Optionally, an SFTP connection is configured for the Customer.
Tooling and access

2	xControl	Open Reports, generate a Detailed Usage Report for the Customer and a period covering the session, and wait for its status.	The status changes from Pending to Success.
3	xControl	Download the report and open it.	A row for the session exists with Site, System, IMSI, MCC, MNC, IP address, start and end time and bytes equal to the session record.
4	xControl	Generate a Summary Usage Report by IMSI for the same period and download it.	The IMSI's totals equal the sum of its session records in the period.
5	Test host	If SFTP delivery is configured, list the SFTP destination.	The report file is present.

Prerequisite procedures	EXP-MOB-005 — Transition from the public radio network to the private radio EXP-MOB-006 — Transition from the private radio to the public radio network

Objective. Each session a Mobile Asset had while moving between the public radio network and the private radio is recorded against the Site that served it, with that network's identifiers, and no record spans the transition.

Preconditions

Tooling and access
- Log in to xControl with an account that holds the ADMIN role.
Procedures executed first

2	—	Execute EXP-MOB-006 — Transition from the private radio to the public radio network as a prerequisite procedure.	As defined in EXP-MOB-006.
3	xControl	Open the Mobile Asset's Event Log after the implicit detach times of both Sites have elapsed.	Two closed records and one open record exist for the three sessions.
4	xControl	Compare the records.	The public sessions name the xRouter site and carry the operator's MCC and MNC; the private session names the private Site and carries the private network's MCC and MNC and its radio identifier. No record has a start time before, and an end time after, a transition.
