APN                                                 Enter the APN.

APN Mode                                      Select an APN mode as one or more of

• Mobile Station provied
• Network provided
• Subscription provied

 

Mobile Station provided

This field is only available when an APN has been entered.

MS-provided PAN, subscription not verified, indicates that the mobile sta- tion (MS) provided the APN and that the HLR did not verify the user’s subscription to the network.

 

Network provided            Network-provided APN, subscription not verified, indicates that the net- work provided a default APN because the MS did not specify one, and that the HLR did no verify the user’s subscription to the network.

 

Subscription verified

MS or Network-provided APN, subscription verified, indicates that the

MS or the network provided the APN and that the HLR verified the user’s subscription to the network.

 

APN Restriction                             Select the type of restriction that you want. You can choose all of the types, or one of the types. You cannot choose multiple types. Types include:

Adding an advanced filtering rule

When adding a rule, use the following formats:

• Prefix, for example, range 31* for MCC matches MCC from 310 to 319.
• Range, for example, range 310-319 for MCC matches MCC from 310 to 319.
• Mobile Country Code (MCC) consists of three digits. The MCC identifies the country of domicile of the mobile subscriber.
• Mobile Network Code (MNC) consists of two or three digits for GSM/UMTS applications. The MNC identifies the home PLMN of the mobile subscriber. The length of the MNC (two or three digits) depends on the value of the MCC. Best practices dictate not to mix two and three digit MNC codes within a single MCC area.
• Location Area Code (LAC) is a fixed length code (of 2 octets) identifying a location area within a PLMN. This part of the location area identification can be coded using a full hexadecimal representation except for the following reserved hexadecimal values: 0000 and FFFE. These reserved values are used in some special cases when no valid LAI exists in the MS (see 3GPP TS 24.008, 3GPP TS 31.102 and 3GPP TS 51.011).
• Routing Area Code (RAC) of a fixed length code (of 1 octet) identifies a routing area within a location.
• CI or SAC of a fixed length of 2 octets can be coded using a full hexadecimal expression.
• Type Allocation Code (TAC) has a length of 8 digits.
• Serial Number (SNR) is an individual serial number identifying each equipment within each TAC. SNR has a length of 6 digits.
• Software Version Number (SVN) identifies the software version number of the mobile equipment. SVN has a length of 2 digits.

You cannot add an advanced filtering rule when creating a new profile. You must add it after the profile has been created and you are editing the profile.
