Abstract

This Network Impact Report describes how the current release of the SAPC 1 affects the previous release of the SAPC 16B FD03 and the operators overall network, including all affected functions.

1 Introduction

This Network Impact Report describes how the current release of the SAPC 1 affects the previous release of the SAPC 16B FD03 and the operators overall network, including all affected functions.

Unless it is stated, this NIR covers both SAPC 16B FD03 to SAPC 1.0 (PNF), and SAPC 16B FD03 to SAPC 1.0 (VNF).

Note:: The adoption of Ericsson SW Model is a requirement before upgrading to SAPC 1.0.

1.1 Purpose

The purpose of this document is to provide information at an early stage to Ericsson system operators to help them plan the introduction of the SAPC 1.0 and upgrade their networks.

This document is a living document and is subject to change during the development of the new release. Therefore, part of the information may be incomplete or unavailable until General Availability (GA) of the SAPC 1.0 release.

2 General Impact

Next sections give information about the SAPC characteristics and describes the differences between SAPC 1.0 deployed as PNF and SAPC 16B FD03 in terms of subscriber capacity, network performance, and memory consumption. Figures given along this document are based on preliminary characteristics measurements on SAPC 1.0.

Information is provided for the network scenarios, traffic models, and configurations detailed in SAPC 1 Network Impact Report.

2.1 Capacity and Performance

2.1.1 PNF Subscriber Capacity and Network Performance

The following tables show the maximum Subscriber Capacity and the maximum Transactions Per Second of SAPC 1.0 per each network scenario. The number of TPS supported for all releases of the Gx interface when executing similar functions is about the same.

The concept of Transaction in this document means a service request and the corresponding reply. The related capacity term is Transactions Per Second (TPS).

External Database Access

The impact of storing subscriber profiles in an external database is determined by the performance of the external database, the parts of the subscriber profile externally stored and the operator data model. According to estimations, the impact in performance using LDAP interface is as follows:

14% reduction in the number of TPS supported, when both subscriber profile and usage accumulators are stored in external database, which needs a write operation to external database.
10% reduction in the number of TPS supported, when no accumulators are stored in the external database.

Mobility Based Policy for Overlay Deployments

The Sx interface, which offers this feature, has been renamed to Smp.

This feature has no impact in the performance for those scenarios where the Smp interface is not used.

The performance of the Smp operation is similar to the performance of Gx operations with similar controls.

The impact on the performance of the feature mostly depends on:

Subscribers that are using the Smp interface.
Smp operations have similar performance demands as Gx operations
Traffic model, that is actual frequencies of the Smp operations. The frequencies of some operations can become high especially those related to location change.

2.1.2 PNF Memory

No information is available for this document release.

2.1.3 VNF Subscriber Capacity, Network Performance, and Memory

For performance information of the SAPC 1.0 deployed as VNF, refer to SAPC 1 Network Impact Report.

2.2 Implementation

2.2.1 PNF Implementation

The SAPC 1.0 introduces new provisioning and configuration databases available through new interfaces. As a consequence, it is not possible to provide a direct upgrade from SAPC 16B FD03 to SAPC 1.0 PNF. The SAPC 16B to SAPC 1.0 upgrade implies a SW reinstallation. The procedure also includes data migration.

The overall reinstallation time and out-of-service impact depends on the execution time of the project.

2.2.2 VNF Implementation

The SAPC 1.0 VNF deployments are considered new network deployments. No upgrade alternative is available in such case.

2.3 Platform

The SAPC 1.0 platform capabilities are provided by a set of Ericsson Component Based Architecture (CBA) common components. This CBA-based platform replaces Telecom Server Platform (TSP) functions offered under SAPC 16B FD03.

To review the list of the common components provided with SAPC 1.0 refer to the Technical Product Description.

SAPC 1.0 provides a merged SW upgrade, meaning that application and common components can be upgraded at the same time.

2.4 PNF Architecture

The SAPC PNF architecture is based on the following function elements:

System Controllers (SCs): Virtual Machines (VMs) executed on top of a virtualized environment based on KVM providing the SAPC OAM and provisioning services.
Traffic Payloads (PLs): Native Physical processors providing the SAPC traffic interface and traffic processing capabilities.

For more information, refer to Availability and Scalability.

2.4.1 PNF Supported HW

2.4.1.1 Supported HW When Upgrading from SAPC 16B FD03

To facilitate SAPC 1.0 adoption by current SAPC 16B FD03 customers, existing installed base HW is supported:

NSP 6.1
BSP 8100

2.4.1.2 Additional PNF Supported HW

The SAPC 1.0 can be deployed in any COTS HW fulfilling at least the minimum HW requirements listed in Technical Product Description.

2.4.1.3 PNF HW Not Supported

NSP 6.0

2.5 VNF Architecture

The SAPC 1.0 VNF architecture consists of several Virtual Machines (VMs) taking different function roles:

System Controllers (SCs): Virtual Machines (VMs) executed on top of a virtualized environment based on KVM providing the SAPC OAM and provisioning services.
Traffic Payloads (PLs): VMs providing the SAPC traffic interface and traffic processing capabilities.
Virtual Router (VR): VMs providing the Virtual Routing Service.

For more information, refer to SAPC VNF Network Configuration Guide and Availability and Scalability.

2.5.1 VNF Infrastructure

The SAPC 1.0 can be deployed as VNF on top of either OpenStack or VMware based NFVI.

2.6 Upgrade

Upgrade procedure in SAPC 1.0 improved providing:

Merged SW upgrade, meaning that application and common components are upgraded at the same time and for all scenarios.
Automatic update of configuration files.
Automatic update of Diameter dictionary files.
Automatic update of PM (counters and threshold alarms).
Automatic update of preconfigured entities.
Upgrade traces for troubleshooting purposes.

2.7 Interface

This section describes interface changes between SAPC 16B FD03 and SAPC 1.0 common functions. Specific impacts on functions detailed as not available or phased-out in Section 4, are not covered in this section.

2.7.1 Traffic Interfaces

The impacts on traffic interfaces are summarized for in Table 9 and Table 10.

Table 9 Impacts on Traffic Interfaces
Interface	Nodes	Impact
ESy	SAPC<->Ericsson Charging System	Minor: The overload protection function is not applied on the ESy interface.
Gx	SAPC<->PCEF	Major: Impacts detailed below.
Gx+	SAPC<->Ericsson PCEF	Major: Gx+ Rel7 and Gx+ Rel8 support is phased-out.
LDAP	SAPC<->External Database	Minor: If the External Database reports LDAP Error Code 51 as response to an LDAP query, DIAMETER_TOO_BUSY (3004) is returned over the Gx interface. The SAPC can use the especial unknown subscriber, and then returns DIAMETER_SUCCESS (2001). The unknown subscriber must be provisioned in the SAPC as explained in Database Access
Rx	SAPC<->AF	Major: Impacts detailed below.
SMPP	SAPC<->SMS Center	No Impact
SOAP Incoming Notification Web Services	SAPC<->External Database	Minor
SOAP	SAPC<->SOAP Notification Server SAPC<->BBSC	No Impact
Sy	SAPC<->OCS	Minor: The overload protection function is not applied on the Sy interface.
Sx	SAPC<-> SGSN-MME	Major: This interface has been renamed to Smp. See Smp impacts detailed below.

Diameter Base Protocol Impacts

SAPC Diameter Base Protocol Errors not supported: DIAMETER_LIMITED_SUCCESS (2002), DIAMETER_UNABLE_TO_DELIVER (3002), DIAMETER_REALM_NOT_SERVED (3003).

SCTP Impacts

SCTP bundling is disabled (default value at installation time). So, the SAPC sends Diameter outgoing messages over SCTP faster.

Gx Impacts

The 3GPP Gx interface has the following impacts on SAPC 1.0:

SAPC supports Gx Rel9 version 9.7.0 or higher versions.
Gx Rel7 and Gx Rel8 support is phased-out. If the PCEF requests session establishment with Gx interface Release 8 or previous, the SAPC returns the error code DIAMETER_INVALID_AVP_VALUE (5004).
Gx Diameter Redirection Agent (DRA) functionality is not available.
The overload protection function does not reject any Gx message other than the Gx session establishment messages, except for emergency session establishments that are not rejected.
Credit-Control-Request (CCR):
- Event-Trigger value not supported: CHARGING_CORRELATION_EXCHANGE.
- 3GPP2-BSID AVP not supported.
- IP-CAN-Type AVP adds support for FBA value.
- Access-Network-Charging-Identifier-Gx AVP not supported.
- AN-Trusted AVP not supported.
Charging-Rule-Install AVP
- Charging-Correlation-Indicator AVP not supported.
Charging-Rule-Definition AVP
- Monitoring-Key AVP not supported.
- Flow-Description AVP uplink (direction 'in') inside Flow-Information AVP not supported.
Charging-Rule-Report AVP
- Rule-Failure-Code AVP adds support of the following values: RATING_GROUP_ERROR (2), SERVICE_IDENTIFIER_ERROR (3), GWPCEF_MALFUNCTION (4), RESOURCES_LIMITATION (5), MAX_NR_BEARERS_REACHED (6), UNKNOWN_BEARER_ID (7), MISSING_BEARER_ID (8), MISSING_FLOW_INFORMATION (9), UNSUCCESSFUL_QOS_VALIDATION (11), INCORRECT_FLOW_INFORMATION (12), and NO_BEARER_BOUND (15).
Application Detection and Control (ADC) error handling:
- When a CCR-U is received with APPLICATION_START or APPLICATION_STOP event trigger, but not Application-Detection-Information AVP or with Application-Detection-Information AVP but not TDF-Application-Identifier AVP inside, the SAPC returns a CCA with error code DIAMETER_MISSING_AVP (5005).
- When a CCR-U is received with APPLICATION_START or APPLICATION_STOP event trigger, with Application-Detection-Information AVP including a Flow-Information AVP, but no corresponding TDF-Application-Instance-Identifier AVP, the SAPC returns a CCA with error code DIAMETER_MISSING_AVP (5005).
Emergency services error handling:
- When the SAPC receives an initial CCR for an emergency session and the emergency subscriber is not provisioned, the SAPC processes the request (does not return DIAMETER_USER_UNKNOWN 5030).

Rx Impacts

The Rx interface has the following impacts on SAPC 1.0:

Rx Rel7 and Rx Rel8 support is phased-out.
- If the AF only supports Rx Rel7 standard, and therefore the Supported-Features AVP is absent from the AAR command, the SAPC returns DIAMETER_MISSING_AVP (5005).
- If the AF requests session establishment with Rx interface Rel 8 standard, the SAPC returns DIAMETER_INVALID_AVP_VALUE (5004).
The overload protection function does not reject any Rx message other than the Rx session establishment messages, except for emergency session establishments that are not rejected.
AA-Request (AAR):
- If there are no policies defined in the SAPC to match the information received in the AA-Request command and classify the relevant dynamic services, then the SAPC responds to the AF with an AA-Answer command including the Experimental-Result-Code AVP set to the value REQUESTED_SERVICE_NOT_AUTHORIZED (5063).
- Specific-Action AVP values CHARGING_CORRELATION_EXCHANGE (1) and IP-CAN_CHANGE (6) not supported.
- If an IMS emergency call binds to a non-emergency IP-CAN session, the SAPC does not ignore the value of Service-URN AVP.
AN-Trusted AVP not supported.
Re-Auth-Request (RAR):
- Access-Network-Charging-Identifier AVP not supported.
- Specific-Action AVP value IP-CAN_CHANGE (6) not supported.
- AN-Trusted AVP not supported.

Smp Impacts

The Smp interface has the following impacts on SAPC 1.0:

CCR not supported AVPs:
- Event-Trigger
- Presence-Reporting-Area-Information
- Session-Linking-Indicator.
CCA not supported AVPs:
- Event-Trigger
- Presence-Reporting-Area-Information
CCA modified AVPs
- MIP6-Agent-Info: multiple AVPs are supported
RARs are not supported
When a CCR-U or CCR-T is received, the SAPC does not perform any control. In case there is no error in the request it returns a CCA with result code DIAMETER_SUCCESS (2001)
Unsupported result codes:
- DIAMETER_LIMITED_SUCCESS (2002)
- DIAMETER_UNABLE_TO_DELIVER (3002)
- DIAMETER_REALM_NOT_SERVED (3003)
- DIAMETER_AUTHORIZATION_REJECTED (5003)
New result codes:
- DIAMETER_CREDIT_CONTROL_NOT_APPLICABLE (4011)

2.8 Operation

2.8.1 Provisioning and Node Configuration

The SAPC 16B FD03 LDAP provisioning and configuration interface is deprecated. As a consequence, all LDAP-based operator provisioning configurations and node configurations must be adapted to support the SAPC 1.0 available provisioning and configuration data models through the new available interfaces.

2.8.1.1 Provisioning Impacts

The SAPC 1.0 provisioning (subscribers, groups, services, profiles, and policy-related data) is managed by a provisioning REST API. This document does not provide the mapping between the SAPC 16B FD03 provisioning LDAP objects and parameters and the SAPC 1.0 REST resources and JSON objects.

The SAPC 1.0 does not provide different levels of administrator profiles to handle provisioning data.

2.8.1.2 Node Configuration Impacts

The SAPC 1.0 node configuration is managed by the COM component which implements a manager-agent architecture. A detailed description for object and attributes can be found in Managed Object Model (MOM). The SAPC 1.0 node configuration data is accessed through the NETCONF interface or the ECLI.

This document does not provide the mapping between the SAPC 16B FD03 LDAP node configuration objects and parameters and the SAPC 1.0 MOM.

2.8.2 Performance Management

The SAPC 1.0 measures report file is based on 3GPP TS 32.435 v10.0.0, XSD type XML file format definition.

The main differences with SAPC 16B FD03 TSP nPMF XSD type XML (3GPP TS 32.435 v6.0.0) are the following:

Newly supported XML elements and attributes: elementType, userLabel, swVersion, job, jobId, repPeriod, suspect, p, r, and measInfoId.
XML element not supported: measResults.

DTD type XML file format support is phased-out in SAPC 1.0. XSD type XML must be used instead.

SAPC 1.0 does not push to an external system, the PM files. OSS/BSS has to pull the PM files, For more information refer to SAPC Measurements.

2.8.2.1 Gx Protocol Measures

The SAPC 1.0 Gx protocol measures impacts are listed below. Compatible measures are listed in Table 13 and new measures are listed in Table 14

For PCEFs configured as clustered Diameter systems, the PCEF peer identifier reported as Measured Object Instance is the Origin-Host received from the PCEF, not the cluster pattern.

2.8.6 Security Management

SAPC 1.0 does not support:

LDAP authentication
New users creation for restricted access to certain resources through Local authentication
Administrator Authorization in the COM NBI

2.8.7 Backup and Restore

The SAPC 1.0 backup and restore functions are provided by the Backup and Restore Management (BRM) Component. For details on the backup and restore operation procedures, refer to Backup and Restore.

The SAPC 1.0 backup has been improved to remove dynamic information that is considered obsolete if restored. The database backup does not store the following information:

IP-CAN sessions.
Time Trigger events.

Only one URI is possible to be used by backup scheduler when automatically exporting a scheduled backup.

2.8.8 License Management

The SAPC 1.0 controls the activation of the purchased functionality by license keys using License Manager (LM) Common Component.

2.8.9 Geographical Redundancy

The SAPC 1.0 geographical redundancy function is based on the replication capability provided by the Database Service (DBS). Any data not stored in the DBS is not replicated. The following data is not stored in DBS and not replicated:

The node configuration data that is provided through COM. Therefore, the configuration data must be provided to each SAPC node individually.
The licensing information. Therefore license information must be managed in each SAPC individually.

The geographical redundancy function is managed using NETCONF or the ECLI. For additional details on the operation of geographical redundancy function, refer to Geographical Redundancy folder.

2.8.10 Graphical User Interface

The SAPC 1.0 introduces the following impacts on the graphical user interface:

The Policy Studio replaces the Business Studio and SAPC GUI. For information, see Policy Studio.
The Ericsson NETCONF browser (ENB) presents configuration data graphically, allowing users to navigate the configuration structure and perform add, modify, and delete operations on configuration elements. The ENB is an Ericsson separate product not directly provided with the SAPC. For more information, refer to Ericsson NETCONF Browser documentation.
The Provisioning Tools document provides an introduction to the Postman Chrome plug-in to interact graphically with the REST API.
TSP-based Node Management Toolbox (and all its associated services including TelORB Manager, Alarm Viewer, Notification Viewer, Redundancy GUI, License Manager, and so on), Load Viewer tool, and Signaling Manager are not available.

2.9 Other Network Elements

For information on SAPC 1.0 compatibility with other Ericsson products, refer to Compatible Network Elements.

3 Additional Information

3.1 Subscription Management

The SAPC 1.0 impacts affecting Subscription management are the following:

"Unknown" subscriber changed to "unknown".
Special "Global" and "Autoprovisioned" dataplans (groups) changed to "global" and "auto" respectively.

3.2 Fair Usage Management

The SAPC 1.0 impacts affecting Fair Usage Management are the following:

Special predefined value “_ReportingGroup_” is renamed “reporting-group”.

3.3 QoS Profile Management

The QoS profile has been subdivided in SAPC 1.0 to differentiate bearer QoS profile (ip-can-session-qos) and service QoS profile (content-qos).

3.4 Database Access Management

The Entity Data Sources are configured inside the SAPC 1.0 internal database, using COM class EDSource MOC. The list of preconfigured Entity Data Sources and its values are simplified in the SAPC 1.0 compared to the SAPC 16B FD03. The SAPC 16B FD03 Entity Data Sources extended by the operator, if any, have to be mapped to the SAPC 1.0 Entity Data Sources definition in the data migration service of the upgrade.

3.5 Policy Management

3.5.1 Policy Types

The SAPC 1.0 impacts affecting Policy Types are the following:

The Policy Locator 'Action' concept is removed.
Policy Locator 'Contexts', Policy Locator 'Resources' and Policy Locator 'Output Attributes' are modeled differently in REST provisioning API. The Policy Locator naming equivalences between SAPC 16B FD03 and SAPC 1.0 are summarized in Table 41, Table 43, and Table 44. Refer to Configuration Guide for Subscription and Policies.
Rule combining algorithms equivalences are summarized in Table 45.

4 Impact on Value Packages

4.1 Base Package

4.1.1 3GPP Gx

The 3GPP Gx function has the following impacts on SAPC 1.0:

Dispersion on reauthorization: The dispersion range mechanism for reauthorization owing to time of day conditions and related configuration variables, are no longer applicable. The reauthorizations are sent as soon as possible limited by a throttling mechanism that can be configured based on network traffic model, and the SAPC capacity.
Subscriber basic session clean up mechanism: When the SAPC receives an IP-CAN session activation request for a subscriber including an APN and an IPv4 or IPv6 prefix address, the SAPC does not check if an IP-CAN session exists for the same subscriber identifier, the same APN, different IP address value of the same type (IPv4 or IPv6 prefix) and same traffic identifier as the received in the activation request. In such a case, both sessions coexist.

For 3GPP Gx interface impacts, refer to tt-gxImpacts.

4.1.2 Basic Policy Control

The Basic Policy Control function has the following impacts on SAPC 1.0:

Session Information Publication not available.
Clustered diameter systems are defined based on a common pattern associated to the received origin host, not a logical node identifier.
Subscriber Group Management default priority at subscriber group level not available.
Temporarily inactive PCC rule status not available.
Subscription removal handling for mobile access: When a UE's subscription is removed, the SAPC does not trigger a RAR to terminate associated sessions.

4.1.3 Dedicated Bearer QoS Control

Mission Critical user plane Push To Talk (MCPTT) not supported. If the QCI allocated to the dynamic service is QCI 65 or 66, the Guaranteed-Bitrate-DL and Guaranteed-Bitrate-UL AVPs are not sent in the PCC rule information.

4.1.4 Default QoS Control

No impacts.

4.1.5 Multiple PCEF Support

No impacts.

4.1.6 Policy Studio

The SAPC Policy Studio replaces SAPC 16B FD03 Business Studio. The SAPC Policy Studio is deployed in an external Linux server. For additional details, refer to Policy Studio.

4.1.7 Restful API for Provisioning

This is a new provisioning interface. The SAPC provisioning is executed through REST operations, defined in the Provisioning REST API. For additional information on the description of the configuration and provisioning data model, refer to Managed Object Model (MOM).

4.1.8 Usage Reporting for Gx

The Usage Reporting function has the following impacts on SAPC 1.0:

Association between preconfigured or dynamic services and their monitoring key is not supported. As a consequence, the monitoring key policy type is not available.
Interaction with external database: Collisions Detection Counter (CDC) mechanism, based on a CDC attribute, not available.
The fair usage validity time dispersion logic is reworked. The configuration variable to add a random number of seconds to the calculated validity time is no longer applicable.
Accumulated usage information is now accessed through REST API.

4.1.9 Flexible Output Protocol

The Flexible Output Protocol function has the following impacts on SAPC 1.0:

Transformations are applied at command level and at service level.
Flexible Output Protocol language syntax has been modified.
Transformations are now provided by Entity Data Targets.
Only Gx protocol is supported.

4.2 Business Intelligence

4.2.1 SOAP Notifications

HTTPS support for SOAP notifications is not available.
A load balancing mechanism is introduced to distribute the delivery of notifications among the set of configured Notification Addresses, belonging to a Notification Server, using round robin algorithm. When the SAPC detects one of the configured Notification Addresses is not available, it stops sending further notifications towards that Notification Address. When the connection towards a Notification Address is restored, the SAPC starts again sending notifications towards this Notification Address.
Connection handling changes:
- The default maximum number of connections per process, between the SAPC and the SOAP notification server are doubled (50).
- The default maximum size of the SOAP notifications queue is doubled (2000).
- The default time period to check the SOAP connection status has doubled to (6000 ms)
- If a connection is not established after the connection reattempts, or the connection is established but the notification delivery fails (an error is received at protocol level), the SAPC inserts this notification in the notification queue at the last position if there is room for one more notification. For the list of specific HTTP supported errors refer to User Notifications.

4.2.2 Unavailable Functions

EBM Analytics for Gx
EBM Analytics for Rx

4.3 Convergence

4.3.1 Fixed Mobile Policy Control

Fixed and convergence policy control is provided through Gx interface. The SAPC supports all Subscription-Id-Type values, so it is possible to use END_USER_NAI or END-USER_PRIVATE traffic identity (for example with a MAC address) for fixed PCC. Radius interface support is phased-out.

4.4 High Availability and Pooling

4.4.1 IP Geographical Redundancy

The SAPC 1.0 provides a new geographical redundancy solution, following the "Primary / Standby" (1+1 redundancy) replication model available in SAPC 16B FD03. For additional details on the geographical redundancy function refer to the Geographical Redundancy Facility Description.

- Maximum of 20 outstanding LDAP requests per LDAP session.
SQL External Repositories not supported.
Collision Detection mechanism is not available.

4.8.2 Mobility-Based Policy for Overlay Deployments

The function managing Mobility-Based Policy has the following impacts on SAPC 1.0:

No controls are executed on session modification, subscriber profile update or ToD session reauthorization. This means:
- Smp RARs are not supported
- Smp CCR-Us are always answered with DIAMETER_SUCCESS (2001)
No Smp session is maintained on the SAPC.
Smp Session Access Control supports a new scenario, where SAPC 1.0 allows returning DIAMETER_CREDIT_CONTROL_NOT_APPLICABLE (4011) to notify the SGSN-MME to continue the IP-CAN session but drop the Smp session. Other Smp Session Access Control scenarios not supported.

Email message notifications are phased-out.
Connection handling changes:
- The default maximum number of connections per process, between the SAPC and the SMS notification server are doubled (50).
- The default maximum size of the SMS notifications queue is doubled (2000).
- If a connection is not established after the connection reattempts, or the connection is established but the notification delivery fails (an error is received at protocol level), the SAPC inserts this notification in the notification queue at the last position if there is room for one more notification. For the list of specific SMPP supported errors refer to User Notifications.
- The maximum waiting time for the acknowledgment of the SMPP connection attempt is not configurable.

4.9.8 Presence Reporting Area

The Presence Reporting Area function has the following impacts on SAPC 1.0:

4.10 Voice Optimization

4.10.1 Dynamic Policy Control

The Dynamic Policy Control function has the following impacts on SAPC 1.0:

The access network charging identifier per service data flow is not available.
On reception of SIP Forking, the SAPC updates the existing PCC rules with additional IP flows and bandwidth, as required. However if a forking leg contains additional media components, then new PCC rules are generated.
The support of ServiceId.MediaComponentId has been deprecated. The output of the Dynamic Service Classification is simply a ServiceId, a string that can have any characters such as ".", "_", and so on. Similarly, the input for the Dynamic Service Qualification (Resource) is simply a ServiceId (a string, not an entity).
The dynamic PCC rule random name generation is improved. It follows a specific format of four elements, delimited by the "@" character, with a maximum size of 63 characters. The PCC rule name begins with the service identifier that results from the dynamic service classification process, then continues with the Media-Component-Number and the Flow-Number, and finally includes a pseudo-random portion derived from the Rx diameter Session-Id.
The notification of IP-CAN Type Change is not supported.
The notification of Signaling Path Status is not supported
If an IMS emergency call binds to a non-emergency IP-CAN session, the SAPC does not ignore the value of Service-URN AVP.
