116 - maximum gateway addresses (GGSN addresses) that can be defined in a single APN profile.
IMEI-Profile (SGSN only)
The IMEI is a unique international mobile equipment identity number assigned by the manufacturer that is used by the
network to identify valid devices. The IMEI has no relationship to the subscriber.
network to identify valid devices. The IMEI has no relationship to the subscriber.
An IMEI profile group is a set of device-specific parameters that control SGSN behavior when one of various types of
Requests is received from a UE within a specified IMEI range. These parameters control:
Requests is received from a UE within a specified IMEI range. These parameters control:
Blacklisting devices
Identifying a particular GGSN to be used for connections for specified devices
Enabling/disabling direct tunnels to be used by devices
IMEI profiles are configured with commands in the IMEI Profile configuration mode. A single IMEI profile can be
associated with multiple operator policies.
associated with multiple operator policies.
For planning purposes, based on the system configuration, type of packet processing cards, type of network (2G, 3G,
4G, LTE), and/or application configuration (single, combo, dual access), the following IMEI profile configuration rules
should be considered:

should be considered:
10 - maximum number of IMEI ranges that can be associated with an operator policy.
1000 - maximum number of IMEI profiles per system (such as an SGSN).
APN Remap Table
APN remap tables allow an operator to override an APN specified by a user, or the APN selected during the normal
APN selection procedure, as specified by 3GPP TS 23.060. This atypical level of control enables operators to deal with
situations such as:
APN selection procedure, as specified by 3GPP TS 23.060. This atypical level of control enables operators to deal with
situations such as:
An APN is provided in the Activation Request that does not match with any of the subscribed APNs; either a
different APN was entered or the APN could have been misspelled. In such situations, the SGSN would reject
the Activation Request. It is possible to correct the APN, creating a valid name so that the Activation Request
is not rejected.
the Activation Request. It is possible to correct the APN, creating a valid name so that the Activation Request
is not rejected.
In some cases, an operator might want to force certain devices/users to use a specific APN. For example, all
iPhone4 users may need to be directed to a specific APN. In such situations, the operator needs to be able to
override the selected APN.
override the selected APN.
An APN remap table group is a set of APN-handling configurations that may be applicable to one or more subscribers.
When a subscriber requests an APN that has been identified in a selected operator policy, the parameter values
configured in the associated APN remap table will be applied. For example, an APN remap table allows configuration
of the following:
When a subscriber requests an APN that has been identified in a selected operator policy, the parameter values
configured in the associated APN remap table will be applied. For example, an APN remap table allows configuration
of the following:
APN aliasing - maps incoming APN to a different APN based on partial string match (MME and SGSN) or
matching charging characteristic (MME and SGSN).
Wildcard APN - allows APN to be provided by the SGSN when wildcard subscription is present and the user has
not requested an APN.
Default APN - allows a configured default APN to be used when the requested APN cannot be used – for
example, the APN is not part of the HLR subscription.
