RNC Configuration Mode Commands

The RNC (radio network controller) configuration mode defines the parameters related to the SGSN connection with an RNC.

This mode is accessed from the IuPS Service configuration mode and the command prompt for this mode will appear similar to:
[<context_name>]hostname(config-ctx-iups-service-rnc)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

rab-asymmetry-indicator

Configures the SGSN to force “Asymmetric-Bidirecitonal” as the RAB Asymmetry Indicator when uplink/downlink bitrates are equal.

ASR 5000

Product:

SGSN


Privilege:

Security Administrator, Administrator


Syntax 
rab-asymmetry-indicator
symmetric-bidirectional force-asymmetric-bidirectionalno rab-asymmetry-indicator
symmetric-bidirectional force-asymmetric-bidirectionaldefault rab-asymmetry-indicator
default | no

Disables the override and sets the indicator based on the symmetry of the bitrates as described for the Default Functionality below.


Usage:

This command defines an override that uses “Asymmetric-Bidirecitonal” as the RAB Asymmetry Indicator when uplink/downlink bitrates are equal (default functionality item #1). This overrides the default functionality (see below) for the RAB indicator in the RAB Assignment Request.

As a result of using this override command, two sets of bitrates, one for downlink and one for uplink, will be included in RAB Assignment Requests for establish or modify per 3GPP TS 25.413.

Default Functionality: The SGSN sets the value of the RAB Asymmetry Indicator based on symmetry of negotiated maximum bitrates in the following manner:

  • If the uplink and downlink bitrates are equal, then it is set to “Symmetric-Bidirectional”.
  • If uplink bitrate is set to 0 kbps, then it is set to “Asymmetric-Unidirectional-Downlink”.
  • If downlink bitrate is set to 0 kbps, then it is set to “Asymmetric-Unidirectional-Uplink”.
  • If the uplink and downlink bitrates are non-zero and different, then it is set to “Asymmetric-Bidirectional”.

Example

Example
Override the use of the “Symmetric-Bidirectional” RAB Asymmetry Indicator for equal up/downlink bitrates with the following command:
rab-asymmetry-indicator
symmetric-bidirectional force-asymmetric-bidirectional
Disable the override with the following command:
no rab-asymmetry-indicator

This command enables/disables the inclusion of the Signaling Indication IE in either or both the RAB Assignment Request and/or the Relocation Request RANAP messages.

Platform:

ASR 5000

Product:

SGSN


Privilege:

Security Administrator, Administrator


Syntax 
ranap signalling-indication-ie { rab-assignment-request [ relocation-request ] | relocation-request [ rab-assignment-request ] }

no ranap signalling-indication-ie 

default ranap signalling-indication-ie
no

Sets the configuration so that the SGSN never includes the IE.

default

Resets the configuration to the default - the SGSN includes the IE in the messages if preconditions are met (see Usage section).

rab-assignment-request | relocation-request

Including one or both of these keywords configures what type of RANAP message will include the IE.


Usage:

The command enables the operator to determine whether the signalling indication information element is included in either or both the RAB Assignment Request and Relocation Request messages during the PDP context setup procedure.

For this command configuration to work so that the IE is included, two preconditions must be met:
  • Received QoS traffic class for the context must be interactive
  • Received QoS has a signalling indication value as optimized

When an RNC receives this IE, the RNC assumes that the customer is using IMS signaling and allocates massive amounts of bandwidth, potentially causing cell congestion. This command enables the operator to determine the usage of this IE which provides the operator with additional session management control.

Example

Example
Use the following command to include the signalling indication IE in the RAB Assignment Request:
ranap signalling-indication-ie rab-assignment-request

Usage:

Use this command to match the 3GPP release support by the RNC. As the 3GPP releases each support differing data rate options - R6 supports HSPA and R7 supports HSPA+ - then selecting the compliance is a method of preforming data rate management on a per RNC basis.

Also use this command to set QoS capping overrides for each RNC separately. Default caps for Release 7 RNC will vary depending upon which overrides are set.

IMPORTANT:

Once caps are set for an RNC, if the RNC release level changes the capping remains the same until the QoS override values are changed for that RNC. Values do not automatically change to the default values appropriate for that release .
