ent-gsmmap-scrn

Use this command to assign the GSM (Global System for Mobile Telecommunication) MAP (Mobile Application Part) screening entries that filter or allow TCAP messages for certain MAP operation codes. The messages are filtered or allowed based on CgPA GTA+NPV+NAIV, CdPA GTA+NPV+NAIV, and forbidden (forbid) parameters. Each CgPA entry is associated with one or more CdPA entries and one or more CgPA entries are associated with a MAP Opcode. This command provisions both CgPA and CdPA entries into the database.

Parameters

Note:

See Point Code Formats and Conversion for a detailed description of point code formats, rules for specification, and examples.

cgsr (mandatory)

CGPA screening reference. This parameter specifies a CGPA entry for an OPNAME.

Range:: ayyy
1 alphabetic character and up to 3 optional alphanumeric characters

opname (mandatory)

Operation code name. This parameter references the operation code (opcode) defined with the ent-gsms-opcode command. GSM Map Screening is performed on the specified address or addresses for the referenced operation code.

Range:: ayyyyyyy
Up to 8 alphanumeric characters

action (optional)

The screening action to take if a message is forbidden as defined by the forbid parameter.

Range:

atierr: Generate an ATI reject message. This option is only valid for ATI MAP operation codes.
discard: Discard the MSU
dupdisc: Route the original message to the duplicate node. The original message will not be sent to the original node. If, however, the duplicate node is not available for routing, the MSU is discarded.
duplicate: Route the message as normal to the original destination and route a copy of the original message to the duplicate node. If the MSU fails to route to the duplicate node, a UIM is generated indicating the duplicate routing failure.
forward: Route the original message to the forward node. The original message will not be sent to the original node. If, however, the forward node is not available for routing, the MSU is routed to the original node.
pass: Route the message as normal to the destination.
route: Route the message as normal to the original destination node; no UIM will be generated. The original destination is the node to which normal GTT would be sent if no GSM MAP actions are taken.

Default:

discard

cdsr (optional)

CDPA screening reference. A CDPA entry for a combination of CGSR and OPNAME.

Range:: ayyy
1 alphabetic character and up to 3 optional alphanumeric characters

Range:: 1-15 digits
Valid digits are 0–9, a-f, A-F

forbid (optional)

Forbidden parameter value. A forbidden parameter for the entered address. If a forbidden parameter is detected, then the message is rejected by the action defined by the action parameter.

Range:

all: All parameters are forbidden. Take the specified screening action defined by the action parameter for messages arriving at the system.
none: None of the parameters are forbidden. Route the message to its destination.
state: Take the specified screening action defined by the naction parameter for messages arriving at the system that contain state as the forbidden parameter for the entered address/operation code combination.

Note:
The state parameter is valid only for GSM ATI messages.
location: Take the specified screening action defined by the naction parameter for messages arriving at the system that contain location as the forbidden parameter for the entered address/operation code combination.

Note:
The location parameter is valid only for GSM ATI messages.

Example

The following example adds a MAP OPNAME of ATI with a range of allowed addresses, defines a forbidden parameter for that range of addresses and an action to take if the forbidden parameter is detected, and sets the NPV and NAIV values. This example is wrapped to the next line for readability:

ent-gsmmap-scrn:saddr=919461:eaddr=919462:opname=ati:action=discard:forbid=state :npv=1:naiv=4:cgsr=fela

The following example adds a MAP OPNAME of ATI of with a range of allowed addresses, defines a forbidden parameter for that range of addresses and an action to take if the forbidden parameter is detected, and sets the NPV and NAIV values. The command also defines an ITU International Point Code with Subsystem Number 5, and forbids by location messages that have an action of forward. This example is wrapped to the next line for readability:

ent-gsmmap-scrn:saddr=919461:eaddr=919462:opname=ati:action=forward:pci=1-1-1 :ssn=5:force=yes:forbid=location:cgsr=fela

The following example adds a MAP OPNAME of XYZ with an allowed hexadecimal address of abcdefabcdefabc, defines the action discard to take if a forbidden parameter is detected, and sets the NPV and NAIV values. The command also defines a CGSR of FELA. This example is wrapped to the next line for readability:

ent-gsmmap-scrn:opname=xyz:saddr=abcdefabcdefabc:npv=10:naiv=10:cgsr=fela :action=discard

Notes

GSM screening entries are handled differently from other screening entries such as GWS (gateway screening) in the system database. The following differences apply to provisioning GSM screening entries:

GSM screening entries can be either single entries or range entries.
Single entries have precedence in screening over range entries. Thus the single entries are searched first and if a match is found, the range entries are never searched.
Range entries can overlap single entries.

In this command, only ITU-international and ITU national point codes support the spare point code subtype prefix (s-).
