What's New in this Release

Features and Enhancements

This section covers a brief description of the features and enhancements introduced in this release.

Feature Description

NITZ Display

The Network Identity and Time Zone Display (NITZ) feature enables the AMF to deliver the network name and time zone information to the UE. This feature ensures that UE receives accurate network name and time zone data, crucial for network operations and user experience.

Command introduced:

network-name { short short_network_name | full full_network_name } — Used to configure short and full network name under TAI-group and TAI- list level.

Default Setting: Disabled – Configuration Required

UE Location Reporting

The event exposure functionality enables the AMF to provide specific event notifications to peer Network Functions (NFs) or external clients, such as the Gateway Mobile Location Center (GMLC). This functionality allows the AMF to expose certain events related to UE to subscribed clients, enabling them to receive updates about these events. This feature provides location information of the UE to GMLC using AMF event exposure mechanism. GMLC subscribes for one time location event report from AMF through UDM.

Command introduced:

enable ngran-location reporting — Used in AMF global configuration mode to enable UE location reporting.

Default Setting: Disabled – Configuration Required

3GPP LI

3GPP Lawful Interception (LI) enables legally sanctioned access to private communications by law enforcement agencies. For more information, contact your Cisco account representative.

Behavior Changes

There are no behavior changes in this release.

Installation and Upgrade Notes

This Release Note does not contain general installation and upgrade instructions. Refer to the existing installation documentation for specific installation and upgrade considerations.

Certificate Validation

AMF software images are signed via x509 certificates. Please view the .README file packaged with the software for information and instructions on how to validate the certificates.

Software Integrity Verification

To verify the integrity of the software image you have from Cisco, you can validate the SHA512 checksum information against the checksum identified by Cisco for the software.

Image checksum information is available through Cisco.com Software Download Details. To find the checksum, hover the mouse pointer over the software image you have downloaded.

At the bottom, you will find the SHA512 checksum. If you do not see the whole checksum, you can expand it by pressing "..." at the end.

To validate the information, calculate a SHA512 checksum using the information in Table 1 and verify that it matches either the one provided on the software download page.

To calculate a SHA512 checksum on your local desktop, refer to the table below.

Table 1. Checksum Calculations per Operating System

Operating System

SHA512 checksum calculation command examples

Microsoft Windows

Open a command line window and type the following command:

> certutil.exe -hashfile filename.extension SHA512

Apple MAC

Open a terminal window and type the following command:

$ shasum -a 512 filename.extension

Linux

Open a terminal window and type the following command:

$ sha512sum filename.extension

OR

$ shasum -a 512 filename.extension

Note

 

filename is the name of the file.

extension is the file extension (for example, .zip or .tgz).

If the SHA512 checksum matches, you can be sure that no one has tampered with the software image or the image has not been corrupted during download.

If the SHA512 checksum does not match, we advise you to not attempt upgrading any systems with the corrupted software image. Download the software again and verify the SHA512 checksum again. If there is a constant mismatch, please open a case with the Cisco Technical Assistance Center.

Operator Notes

Cloud Native Product Version Numbering System

The show helm list command displays detailed information about the version of the cloud native product currently deployed.

The appropriate version number field increments after a version has been released. The new version numbering format is a contiguous sequential number that represents incremental changes between releases. This format facilitates identifying the changes between releases when using Bug Search Tool to research software releases.
