> IuPS Service Configuration Mode Commands
> The IuPS Service configuration mode is used to define properties for the IuPS service which controls the Iu-PS interface connections to Radio Network Controllers (RNCs) of the UMTS Terrestrial Radio Access Network (UTRAN).
> In this mode, the prompt will appear similar to:
> [<context_name>]hostname(config-ctx-iups-service)#
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

> This keyword resets the configuration to the default cause ID number.
> ranap-cause cause_number
> This number identifies the reason the SGSN has detected, from Iu Release messages, for the loss of radio coverage (LORC). This value is included in the IE messages the SGSN sends to either the GGSN or the GGSN and the peer SGSN to indicate LORC state. The range of reasons is a part of the set defined by 3GPP 25413.
> cause_number : Must be an integer from 1 to 512.
> Default: 46 (MS/UE radio connection lost)
> Usage
> By defining a cause code, the SGSN knows to detect the LORC state of the mobile from Iu Release messages it receives for the subscriber. This configuration also instructs the SGSN to include the defined cause code for the LORC state in the IE portion of various messages sent to the GGSN and optionally the peer SGSN.
> This command is one of the two commands required to enable the SGSN to work with the GGSN and, optionally the peer SGSN, to implement the Overcharging Protection feature (see the SGSN Overview in the SGSN Administration Guide for feature details. The other command needed to implement the Overcharging Protection feature is the gtp private extension command explained in the SGSN APN Policy Configuration Mode chapter of the Command Line Interface Reference.
> Example
> Use the following command to set the cause code to indicate that there are no radio resources available in the target cell, cause 53.
> loss-or-radio-coverage ranap-cause 53

> plmn id mcc mcc_num mnc mnc_num [ network-sharing common-plmn mcc mcc_num mnc mnc_num [ plmn-list mcc mcc_num mnc mnc_num [ mcc mcc_num mnc mnc_num+ ] ] ]
> no plmn id
> no
> Removes the PLMN ID from the configuration.
> id
> Creates a PLMN configuration instance based on the PLMN ID (comprised of the MCC and MNC). In accordance with TS 25.413, the SGSN supports up to 32 PLMN configurations for shared networks.
> mcc mcc_num
> Specifies the mobile country code (MCC) portion of the PLMN’s identifier.
> mcc_num: The PLMN MCC identifier and can be configured to any integer value between 100 and 999.
> mnc mnc_num
> Specifies the mobile network code (MNC) portion of the PLMN’s identifier.
> mnc_num: The PLMN MNC identifier and can be configured to any 2-digit or 3-digit value between 00 and 999.
> network-sharing common-plmn mcc mcc_num mnc mnc_num
> When network sharing is employed, this set of keywords is required to define the PLMN ID of the common PLMN. The common PLMN is usually not the same as the local PLMN.
> plmn-list mcc mcc_num mnc mnc_num
> When network sharing is employed and more than two PLMNs are available, then use the plmn-list keyword to begin a list of all additional PLMNs.
> Usage
> Use this command to configure the PLMN associated with the SGSN. There can only be one PLMN associated with an SGSN unless one of the following features is enabled and configured: network sharing or multiple PLMN.
> For network sharing, use of the network-sharing keywords make it possible to identify more than one PLMN. Including the PLMN identified initially. None have precedence. They are all treated equally but they must each be unique. In a MOCN configuration, the PLMN list will not be used as there would only be one local PLMN.
> For multiple PLMN support, the SGSN can support up to 8 Iu-PS configurations for PLMNs. These Iu-PS service configurations must be associated with the SGSN via the ran-protocol command in the SGSN Service configuration mode.
> Example
> Use the following command to identify a PLMN and instruct the SGSN to perform network sharing with a single PLMN:
> plmn id mcc 313 mnc 23 network-sharing common-plmn mcc 404 mnc 123
