Feature Description


Important

5G NSA feature is license controlled from release 21.8 onwards. Contact your Cisco account representative for detailed information on specific licensing requirements.

The 5G NSA solution for SAEGW supports the following functionalists:

  • High Throughput

    5G NR offers downlink data throughput up to 20 Gbps and uplink data throughput up to 10 Gbps. Some interfaces in EPC have the support to handle (encode/decode) 5G throughput. For example, NAS supports up to 65.2 Gbps (APN-AMBR) and S5/S8/S10/S3 (GTP-v2 interfaces) support up to 4.2 Tbps. The diameter interfaces S6a and Gx support only up to 4.2Gbps throughput, S1-AP supports only up to 10 Gbps and NAS supports up to 10 Gbps (MBR, GBR). New AVP/IE have been introduced in S6a, Gx , S1-AP, and NAS interfaces to support 5G throughput. See the How It Works section for more information.

  • DCNR Support on P-GW:

    Supports configuration of DCNR feature at the P-GW-service, by configuring “Extended-BW-NR” feature in IMSA service. Advertises the DCNR feature support by sending “Extended-BW-NR” feature bit in “Feature-List-ID-2” towards PCRF. Forwards AVP "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" in CCR messages when it receives APN-AMBR values greater than 4.2Gbps from MME/S-GW. Decodes the extended AVP "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" when it is received from PCRF.

  • Sends AVP "Extended-Max-Requested-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL" and "Extended-GBR-DL" when it receives MBR and GBR values greater than 4.2Gbps from MME/S-GW. Decodes the AVP "Extended-Max-Requested-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL" and "Extended-GBR-DL" when received from PCRF. Supports dedicated bearer establishment with extended QoS. Sends AVP Extended-Max-Requested-BW-UL and "Extended-Max-Requested-BW-DL" in Gy records.

  • Ultra Low Latency Support:

    Supports 5G requirements of Ultra-Reliable and Low Latency Communications (URLLC). 3GPP introduced URLCC QCI 80 (Non-GBR resource type), QCI 82 and 83 (GBR resource type). P-GW establishes default bearers with URLLC QCI 80, which is typically used by low latency eMBB applications. P-GW establishes dedicated bearers with URLLC QCI 82 and 83 (also with QCI 80 if dedicated bearers of Non-GBR type to be established), which is typically used by discrete automation services (industrial automation).

  • ICSR Support

    With release 21.10 onwards ICSR for 5G NSA on SAEGW is supported.

  • Dynamic S-GW and P-GW selection by MME for DCNR capable UE

    When DCNR capable UE attempts to register in MME and when all DCNR validations are successful (for example DCNR feature configuration on MME, HSS not sending access-restriction for NR, and son on), the MME sets “UP Function Selection Indication Flags” IE with DCNR flag set to 1 in “Create Session Request” message. This feature is relevant for CUPS architecture to help SGW-C and PGW-C to select SGW-U and PGW-U which supports dual connectivity with NR. When S-GW receives this IE over S11, it sends this IE over S5 to P-GW. S-GW ignores IE if it receives it in Non-CUPS deployment.

  • P-GW Secondary RAT Usage Data Report Handling:

    P-GW supports custom24 and custom44 for Gz and aaa-custom3, aaa-custom4 and aaa-custom6 dictionaries for Rf to support Secondary RAT Data Usage Report in CDRs.

Support for Secondary RAT Usage During GnGp Handover

This feature supports the Secondary RAT usage reported in change notification request during 4G to 3G handover. The support is for handling the change notification with Secondary RAT Usage during the GnGp handover. Step 13 is added in the following diagram in support of this feature. The usage must be reported in next CDR generation.

IMSI Not Known

If there’s no context found for IMSI specified in Secondary RAT Usage IE of change notification request Message, it returns the change notification response with cause value "IMSI/IMEI not known".

Limitations

Following are the known limitations for this feature:

  • This feature only supports the handling of the secondary RAT usage IE.

  • During the 4G to 3G handover, dedicated bearers are retained and Secondary RAT usage is reported for both Default and Dedicated bearers.

How It Works

Architecture

This section describes the architecture for Gx (PCRF), Gy (OCS), Gz (P-GW), and Rf (P-GW) interfaces with respect to 5G NSA for SEAEGW feature.

Gx (PCRF)

The Gx interface supports new AVPs to handle 5G throughput for default bearers and dedicated bearers. Gx interface introduced new "AVP Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" in grouped "AVP QoS-Information" and "Conditional-APN-Aggregate-Max-Bitrate" to handle 5G throughput for default bearers. New AVPs "Extended-GBR-UL", "Extended-GBR-DL", "Extended-Max-Requested-BW-UL" and "Extended-Max-Requested-BW-DL" are added in grouped AVP "QoS-Information" for dedicated bearers.

When the maximum bandwidth value set for UL or DL traffic is higher than 4294967295 bits per second, the "Max-Requested-Bandwidth-UL" or DL, AVP must be present, and set to its upper limit 4294967295 along with the "Extended-Max-Requested-BW-UL" or DL must be present, and set to the requested bandwidth value in kilobits per second. The same principal applies for "Extended-GBR-UL/DL" and "Extended-APN-AMBR-UL/DL".

The following new AVPs are introduced in the grouped AVP QoS-Information:

  • Extended-Max-Requested-BW-UL

  • Extended-Max-Requested-BW-DL

  • Extended-GBR-UL

  • Extended-GBR-DL

  • Extended-APN-AMBR-UL

  • Extended-APN-AMBR-DL

the following new AVPs are introduced in the grouped AVP Conditional-APN-Aggregate-Max-Bitrate.

  • Extended-APN-AMBR-UL

  • Extended-APN-AMBR-DL

Gy (OCS)

New AVPs "Extended-Max-Request-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL", "Extended-GBR-DL", "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" in grouped AVP “QoS-Information” are introduced Gy interface to handle 5G throughput for dedicated bearers.

When the maximum bandwidth value set for UL/DL traffic is higher than 4294967295 bits per second, P-GW sets the "Max-Requested-Bandwidth-UL/DL" AVP to its upper limit 4294967295 and sets the "Extended-Max-Requested-BW-UL/DL" to the required bandwidth value in kilobits per second in CCR-I/CCR-U messages. The same principal applies for "Extended-GBR-UL/DL" and "Extended-APN-AMBR-UL/DL".

5G NSA feature supports Gy dcca-custom1, dcca-custom7, dcca-custom8, standard dcca-custom13 and dcca-custom26 dictionaries.

Gz (P-GW)

c

New sequence of container in PGWRecord for PGW-CDR to support RAN secondary RAT usage data report is introduced in Gz interface. AVPs "listOfRANSecondaryRATUsageReports" and "RANSecondaryRATUsageReport" are introduced.

New AVPs "Extended-Max-Requested-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL", "Extended-GBR-DL", "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" are introduced over Gz interface as part of existing "EPCQoSInformation" AVP to handle 5G throughput for default and dedicated bearers.

Rf (P-GW)

New AVPs "RAN-Secondary-RAT-Usage-Report" which is grouped type to support secondary RAT usage data report values is introduced in Rf interface. This contains the volume count as reported by the RAN for the secondary RAT(separated for uplink and downlink) including the time of the report.

AVPs "Extended-Max-Requested-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL", "Extended-GBR-DL", "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" are introduced over Rf interface to handle 5G throughput for default and dedicated bearers.

Gz(S-GW)

New sequence of container in SGWRecord for SGW-CDR to support RAN secondary RAT usage data report is introduced in Gz interface. AVPs "listOfRANSecondaryRATUsageReports" and "RANSecondaryRATUsageReport" are introduced.

New AVPs "Extended-Max-Requested-BW-UL", "Extended-Max-Requested-BW-DL", "Extended-GBR-UL", "Extended-GBR-DL", "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL" are introduced over Gz interface as part of existing "EPCQoSInformation" AVP to handle 5G throughput for default and dedicated bearers.

Limitations

This section describes the known limitations for 5G NSA feature

  • 5G NSA supports Gx standard dictionary (r8-gx-standard), dpca-custom11, dpca-custom15, dpca-custom17, dpca-custom19, and dpca-custom23.

  • 5G NSA has been implemented for Gy dictionaries—dcca-custom1, dcca-custom7, dcca-custom8, standard dcca-custom13 and dcca-custom26 . In order to support NSA for other Gx and Gy dictionaries, dynamic dictionary must be built. Contact your Cisco Account representative for more details.

  • Secondary RAT usage data report will not carry start or end time values prior to “00:00:00 UTC, Thursday, 1 January 1970".

Flows

Initial Registration by DCNR Capable UE

This section describes the following call flows related to the DCNR feature.

Step

Description

1

The DCNR capable UE sets the "DCNR bit" in the NAS message "Attach Request" of "UE Network Capability" IE.

2

MME successfully authenticates the UE.

3

As part of the authorization process, while sending ULR to HSS, MME advertises the DCNR support by sending “NR as Secondary RAT" feature bit in “Feature-List-ID-2".

4

HSS sends ULA by advertising the DCNR by sending "NR as Secondary RAT" feature bit in “Feature-List-ID-2" and sends Max-Requested-Bandwidth-UL as 4294967295 bps, Max-Requested-Bandwidth-DL as 4294967295 bps and the extended bandwidth values in new AVPs "Extended-Max-Requested-BW-UL" and "Extended-Max-Requested-BW-DL".

If HSS determines that the UE is not authorized for DCNR services, HSS sends Subscription-Data with “Access-Restriction" carrying “NR as Secondary RAT Not Allowed".

5

MME sends Create Session Request with the extended APN-AMBR values in existing AMBR IE. As the APN-AMBR values in GTP-v2 interface are encoded in kbps, the existing AMBR IE handles the 5G NSA bit rates.

6

P-W sends CCR-I to PCRF advertising the DCNR by sending “Extended-BW-NR" feature bit in “Feature-List-ID-2". P-GW also sends "APN-Aggregate-Max-Bitrate-UL" as 4294967295 bps, "APN-Aggregate-Max-Bitrate-DL" as 4294967295 bps and the extended bandwidth values in new AVPs "Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL".

7

PCRF sends CCA-I advertising the DCNR by sending the “Extended-BW-NR" feature bit in “Feature-List-ID-2". PCRF also sends "APN-Aggregate-Max-Bitrate-UL" as 4294967295 bps and "APN-Aggregate-Max-Bitrate-DL" as 4294967295 bps and the extended bandwidth values in new "AVPs Extended-APN-AMBR-UL" and "Extended-APN-AMBR-DL". PCRF offers the same extended APN-AMBR values requested by PCEF or modify the extended APN-AMBR values. P-GW enforces the APN-AMBR values accordingly.

8

P-GW honors the APN-AMBR values as offered by PCRF and sends the extended APN-AMBR values in existing IE APN-AMBR in the Create Session Response message.

9

MME computes the UE-AMBR values and sends the extended UE-AMBR values in new IEs “Extended UE Aggregate Maximum Bit Rate Downlink" and “Extended UE Aggregate Maximum Bit Rate Uplink" by setting the legacy “UE AMBR Uplink" and “UE AMBR Downlink" values to the maximum allowed value 10000000000 bps(10 Gbps) in Initial Context Setup Request.

MME sends the APN-AMBR values up to 65.2 Gbps in existing IE APN-AMBR in NAS Activate Default EPS Bearer Context Request – Attach Accept. If the APN-AMBR values are beyond 65.2 Gbps, MME sends the extended APN-AMBR values in new IE “Extended APN aggregate maximum bit rate.

If ULA is received with “Access-Restriction" carrying “NR as Secondary RAT Not Allowed", MME sends the “Initial Context Setup Request" with “NR Restriction" bit set in “Handover Restriction List" IE. Also MME sets the "RestrictDCNR" bit to "Use of dual connectivity with NR is restricted" in the EPS network feature support IE of the Attach Accept message. Accordingly, UE provides the indication that DCNR is restricted to the upper layers.

If DCNR is not configured at MME service or call control profile level, MME sets the RestrictDCNR bit to "Use of dual connectivity with NR is restricted" in the EPS network feature support IE of the Attach Accept message. Accordingly, UE provides the indication that DCNR is restricted to the upper layers.

10

eNodeB sends the Initial Context Setup Response message. If master eNodeB determines to establish the bearer on secondary eNodeB, F-TEID of secondary eNodeB may be sent in this step (Transport layer address and TEID of secondary eNodeB). It is transparent to MME if the bearer is established on master eNodeB or secondary eNodeB.

11

eNodeB sends Uplink NAS Transport with NAS message Attach Complete - Activate Default EPS Bearer Context Accept.

12

MME sends Modify Bearer Request to S-GW with S1-U FTEID details as received in the Initial Context Setup Response message.

13

MME receives the Modify Bearer Response message from S-GW.
