Feature Description

The APN, QCI and ARP-based DSCP Mapping for WPS Sessions feature enables P-GW and S-GW to support DSCP marking based on APN, QCI and ARP functionality for Wireless Priority Service subscribers.

Prioritization of Control Plane Traffic: WPS user’s control plane traffic is prioritized over other subscribers between different Network Functions in the LTE Core.

Priority Levels: P1, P2, and P3 are the three priority levels available for WPS users:

  • P1 and P2 users are identified in HSS/PCRF and GW uses their priority (APN, QCI, and ARP) during default and dedicated bearer creation, modification, update, or deletion.

  • P1 and P2 WPS users are always treated as High Priority.

  • DSCP markings for prioritized user’s control plane IP packets is marked with DSCP=47 while all other users control packets IP packets is marked with DSCP=32.

  • Non-WPS users and P3 WPS users (for example, with QCI=5 and ARP PL =5) are given high priority dynamically based on a call being placed. Example: WPS-P1 user calling non-WPS user.

  • For the LTE Core, the indication of higher priority for a user comes over Rx based on the presence of MPS-Identifier-AVP and value of Service-Info-Status-AVP in the Rx-AAR. PCRF takes appropriate actions and then propagates appropriate QCI, ARP values over to P-GW on Gx session.

Diameter Interfaces:

  • P-GW, Policy Change Rule Function (PCRF), and Diameter Routing Agent (DRA) uses the configuration of Diameter interfaces such as Gx and Rx interfaces to support policy and charging control for subscribers.

Non-Diameter Interfaces: P-GW and S-GW uses non-diameter interfaces such as S5, S8, S11, or S1U with its peer respectively.

Characteristics of Low and High Priority Channels for Diameter based Interfaces

Low Priority channels are used for non-WPS user sessions and High Priority channels are used for WPS user sessions. These channels are identified by different Differentiated Services Code Point (DSCP) markings. The peer connections towards DRA for PGW (Gx) isshown in the figure.

How it Works

The following is a high-level overview of how this feature works.

The P-GW/S-GW selects either High Priority or Low Priority channels based on the wps profile. The following table describes the DSCP marking rules based on the configured APN name, QCI values, and ARP PL in the default or any of the dedicated bearer of a session. WPS session detection is based on the configured APN name, QCI and ARP PL values in the default or dedicated bearer of a session. The S5, S8 and S11 interface contain IP packets marked with DSCP=47 IP based on APN, QCI, and ARP PL parameters as shown in the table. Other IP packets are marked with DSCP=32.

Table 4. Procedure

Process

Description

Identifying WPS and Non-WPS users

  • Use the CLI command priority-select at diameter end point to enable or disable WPS users. This CLI command is at policy-control configuration in IMS-authorization service.

  • P-GW receives Create session request with every WPS session is tagged with the APN name, QCI, and ARP PL values.

  • P-GW verifies whether that APN name, QCI, and ARP PL value is matching the WPS.

  • Session Manager checks whether the received ARP PL value matches the WPS session or not.

  • If the above criteria of matching WPS session and enabling of priority select is met then, the user is called as WPS user. Else, the user is called as Normal user.

Prioritizing Session

At Policy Change Rule Function (PCRF) you can define two priority levels such as Low Priority session for non-WPS users and high priority session for WPS users.

  • Always-On WPS Sessions: GTPv2-S5, GTPv2-S11, GTPv2-S8, and Gx sessions, which belongs to WPS users are always treated as high priority.

  • On-Demand WPS Sessions: GTPv2-S5, GTPv2-S11, GTPv2-S8, and Gx sessions, which belong to Non-WPS users can be uplifted to higher priority (lower ARP PL value) dynamically. The most common example of this is when a WPS user makes a WPS call (that is initiated by dialing a call starting with *272) to non-WPS user. These types of sessions are called On-Demand WPS sessions.

  • Control plane Gx messages belonging to high priority sessions shall use High Priority channels.

  • Control plane Gx messages belonging to non-high priority sessions shall use low priority channels.

Differentiating paths between normal users and WPS users

On Gx interface, different connections are made to form the second path at the CLI level:

  • P-GW creates two sets of DRA peer connections. One set for higher priority and other for normal priority messages.

  • P-GW sends CCR-Initial and CCR-Update Gx messages on specific pair of connections based on type of session (WPS session or non WPS session).

  • After the peer is configured with priority-select flag, all CCR messages for WPS session is initiated over High Priority peer. if P-GW identifies the users as a WPS user it will bind to the high priority peer with DSCP marking as 47. However, non WPS subscriber’s Diameter message is initiated over Low Priority peer and the DSCP is set to 32.

Note 
If the DSCP configuration for peer is not specified, then global dscp value configured under diameter endpoint is used. If global dscp value under diameter endpoint is not configured, then dscp value "0" is used.

The following actions are performed before triggering CCR-I message with respect to WPS users:

  • Selection of High Priority peer.

  • If an existing AVP string is configured in peer configuration, Origin Host ID is appended with a string. If string is not configured, default -wps string is appended to Origin Host ID.

  • DRA/PCRF responds with CCA-I over high priority channel upon reception of the CCR-I. The subsequent messages follow the high priority channel.

Call Flow

The key call flow for this feature include transitioning from non-WPS to WPS Session and PCRF initiated Bearer Deletion.

If CSR (Creation Session Request) has one bearer and ARP PL, QCI does not match with ARP PL, QCI defined in WPS profile for corresponding APN, the Session is treated as Non-WPS Session. All Gx messages follow low priority channel to PCRF. However, if any dedicated bearer triggered by Mobile has ARP PL, QCI matched with ARP PL, QCI in WPS profile for corresponding APN , low priority session is transitioned to WPS session.


Note
"Green peer" is "Low priority channel". "Red peer" is "High priority channel"
Figure 2. Transitioning from Non-WPS to WPS Session and Vice Versa
Table 5. Procedure

Step

Description

1 through 6

Low Priority channels are used for a non-WPS session.

7 through 14

P-GW receives dedicated bearer with APN, ARP PL, QCI matched with ARP PL in WPS APN profile, the following operations are performed, and CCR-U is sent to DRA/PCRF.

  • Non-WPS session is transitioned to WPS session. CLP is updated as WPS session.

  • P-GW Identifies high priority peer.

  • Appends the String “-wps” or configured origin-host-suffix string to Origin host ID.

The subsequent outgoing messages on Gx, S5, S11, or S8 will follow the high priority channel until the session is downgraded again.

15 through 22

P-GW receives RAR with QCI or ARP PL that are not defined in WPS APN profile, the session is downgraded from WPS session to non-WPS.

Configuring IMS Authorization Service for WPS

Use the following sample configuration to configure IMSA service at context level for IMS subscribers: 

configure 
   context context_name 
      ims-auth-service imsa_service_name 
         policy-control 
            diameter origin endpoint endpoint_name priority-select 
            diameter dictionary dictionary 
            no event-report-indication 
            custom-reauth-trigger  qos-change default-bearer-qos-change  ue-ip-addr-allocate resource-modification-request  ue-ip-addr-release apn-ambr-mod-failure default-bearer-qos-mod-failure 
            diameter host-select table { 1 | 2 } algorithm round-robin 
            diameter host-select row-precedence  precedence_value  table { 1 | 2 } host  primary_host_name  [ realm  primary_realm_id  ] [ secondary host  secondary_host_name  [ realm  secondary_realm_id  ] ] priority-host [ -noconfirm ] 
            exit 
         exit

NOTES:

  • context_name must be the name of the context where you want to enable IMSA service.

  • imsa_service_name must be the name of the IMSA service to be configured for Rel. 8 Gx interface authentication.

  • To enable Rel. 8 Gx interface support, pertinent Diameter dictionary must be configured. For information on the specific Diameter dictionary to use, contact your Cisco account representative.

  • The Round Robin algorithm for PCRF selection is effective only over a large number of PCRF selections, and not at a granular level.

  • priority-select: Enables Wireless Priority Services (WPS) for subscribers. This is a mandatory parameter to define peer as Red peer.


    Note
    priority-select keyword is used under IMSA as well as under 'diameter endpoint' configuration. Both must be enabled for current feature to work.

  • priority-host : Configures host as red host. If priority-host keyword configured in a row, both primary and secondary peers are treated as red host .


    Note
    To remove this keyword, configure no-priority-host .

Configuring DSCP Mapping

This section describes how to configure the DSCP mapping:

  • Configuring a WPS APN Profile.

  • Associating an WPS profile with P-GW and S-GW service

  • Enabling Gx Prioritization for WPS Sessions

  • Differentiating Low Priority and High Priority Peers

Configuring WPS APN Profile

Use the following commands to configure WPS APN profile, which is used to identify a bearer or session as an WPS bearer or session. 

configure 
      wps-apn-profile  wps_apn_name 
      [ no ] wps-apn-row row_number qci qci_value earp arp_pl_value dscp dscp_value 
end

NOTES:

  • wps-apn-profile wps_apn_name : Configures WPS profile for an APN. This APN name is used for wps session detection. wps-apn-profile all is used when this WPS APN Profile is to be applied for all APNs.


    Important
    Different wps-apn-profile must be defined for different APNs.

  • wps-apn-row : This configuration is used for marking a bearer/PDN as an WPS. QCI and eARP PL are used for wps session detection. You can configure maximum of 16 rows and an integer value from 1 to16.

    For the qci and earp , all is the wild card match.

  • dscp: This configuration is used at S-GW or P-GW, to mark various outgoing GTP-C and Gx messages associated with an WPS PDN with configured DSCP marking. The dscp value is an integer between 1..63.

Associating WPS APN Profiles with P-GW and S-GW Services

This section describes how to associate a WPS APN profile with P-GW and S-GW services.

configure 
   context  context_name 
      [ no ] pgw-service service_name 
         [ no ] associate wps-apn   
         end

Notes:

  • no : Disables WPS APN profile association with P-GW service.

  • associate wps-apn : Associates WPS APN profile with P-GW service. 

configure 
   context context_name 
      [ no ] sgw-service  service_name 
         [ no ] associate wps-apn  
         end

Notes:

  • no : Disables WPS APN profile association with S-GW service.

  • associate wps-apn : Associates WPS APN profile with S-GW service.

Enabling Gx Prioritization for WPS Sessions

This section describes how to enable Gx prioritization levels for WPS sessions

configure 
   context context_name 
      [ no ]ims-auth-service service_name 
         [ no ] policy control  
             [ no ] diameter origin endpoint  endpoint_name  priority-select 
             [ no ] diameter session-prioritization 
             diameter host-select row-precedence precedence_value table { 1 | 2 } host primary_host_name [ realm primary_realm_id ] [ secondary host secondary_host_name [ realm secondary_realm_id   ] ]  priority-host [ -noconfirm ] 
         end

Notes:

  • priority-select : Enables Wireless Priority Services (WPS) for the selected IMS authorization service.


    Note
    The priority-select keyword is mandatory for WPS feature.

  • no diameter session-prioritization : Enables or disables Gx signalling prioritization for WPS sessions:

    • By default, the diameter session-prioritization CLI command is disabled and Gx messages does not get prioritized based on WPS value.

    • If previously configured, use the no diameter session-prioritization CLI command to set the default behavior

    • The diameter session-prioritization CLI takes effect when Gx, along with WPS APN profile, is enabled in the configuration.

    • The diameter session-prioritization configuration attaches DRMP-0 AVP to Diameter Messages going over the High Priority channel. DRA/PCRF takes appropriate actions based on DRMP-0, incase of fallback from High Priority to Low Priority channel takes place on P-GW to DRA or DRA to PCRF Gx links.


      Note
      Diameter session-prioritization is an existing CLI and it is not mandatory for configuring WPS feature.

    • priority-host : Configures host as red host. If priority-host keyword configured in a row, both primary and secondary peers are treated as red host.

Differentiating Low Priority and High Priority Peers

This section describes how to differentiate between low and priority peers. Priority-endpoint configuration under policy-control ensures WPS feature is only applicable to IMS auth service under policy control area. It is applicable for Gx interface 

configure 
   context context_name 
      [ no ] diameter endpoint pgw-gx  
         peer  primary_peer_name [ realm primary_realm_name ] address ip_address [ port port_number ] 
            peer  secondary_peer_name [ realm secondary_realm_name ] address ip_address [ port port_number ] priority-select dscp dscp_value origin-host-suffix suffix_name 
            end

NOTES:

  • priority-select : Defines peer as high priority wps peer. It is optional to configure to both parameters. Following conditions apply during peer configuration:

    • If priority-select is not configured, peer will not be treated as high priority WPS peer.

    • If no DSCP at peer is configured, endpoint level DSCP is filled in IP packets towards DRA/PCRF. Otherwise, configured DSCP is filled in IP packet.

    • If Priority-select is set and origin-host-suffix is configured in peer, configured string is added to Origin Host ID. Otherwise, default “-wps” string is added to origin host id (for example, pgw-gx-wps).

    • dscp : DSCP can also be configured on low priority peer. The dscp value is a integer between 1..63.
