27-177 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Viewing Operator Policies, APN Remaps, and APN Profiles governing the services, facilities, and privileges available to subscribers. These policies can override standard behaviors and provide mechanisms for an operator to get around the limitations of other infrastructure elements, such as DNS servers and HSSs. NoteOperator policies and APN profiles are applicable only for the ‘local’ context in the logical inventory. The following topics explain how to view operator policies, APN remaps, and APN profiles in the Vision client: Viewing Operator Policies, page 27-177 Viewing APN Remaps, page 27-179 Viewing APN Profiles, page 27-181 Viewing Operator Policies Operator policies provide an operator with a range of control to manage the services, facilities, and privileges available to subscribers. By configuring the various components of an operator policy, the operator fine tunes any desired restrictions or limitations needed to control call handling and this can be done for a group of callers within a defined IMSI range or per subscriber. Besides enhancing operator control through configuration, the operator policy feature minimizes configuration by drastically reducing the number of configuration 4.3.2 needed. Operator policy maximizes configurations by breaking them into the following reusable components that can be shared across IMSI ranges or subscribers: Call-control profiles IMEI profiles (SGSN only) APN profiles APN remap tables Operator policies IMSI ranges To view operator policies in logical inventory: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory >local> Mobile > Policy > Operator Policies The Vision client displays the list of operator policies configured under the container. You can view the individual policy details from the table on the right pane or by choosing Logical Inventory > local> Mobile > Policy > Operator Policies > Po l i c y. Table 27-118 describes the details available for each operator policy. If an operator policy is configured with IMEI ranges and APN entries, the details are displayed in the respective tabs IMEI Ranges and APN Entries on the content pane.

27-179 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Viewing Operator Policies, APN Remaps, and APN Profiles Viewing APN Remaps An 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 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 rejects 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 or users to use a specific APN. For example, a set of mobile users may need to be directed to a specific APN. In such situations, the operator needs to 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 are 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 (SGSN only). 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. APN remap tables are configured with commands in the APN Remap Table configuration mode. A single APN remap table can be associated with multiple operator policies, but an operator policy can only be associated with a single APN remap table. To view APN remap properties in logical inventory: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory > local> Mobile > Profile > APN Remaps The Vision client displays the list of APN remaps configured under the container. You can view the individual APN remap details from the table on the right pane or by choosing Logical Inventory > local> Mobile > Profile > APN Remaps > APN Remap. Table 27-119 describes the details available for each APN remap. If an APN remap is configured with charging characteristics and NI and OI entries, the details are displayed in the respective tabs Charging Characteristics, Network And Operator Identifier Entries, and Default APN Entries on the content pane.

27-181 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Viewing Operator Policies, APN Remaps, and APN Profiles NoteIf a default APN is configured for the remap, click the Default APN tab to view the APN details. In the APN remap table you can configure four default APNs. Viewing APN Profiles APN Profile defines a set of parameters controlling the SGSN or MME behavior, when a specific APN is received or no APN is received in a request. An APN profile is a key element in the Operator Policy feature. An APN profile is not used or valid unless it is associated with an APN and this association is specified in an operator policy. Essentially, an APN profile is a template which groups a set of APN-specific commands that may be applicable to one or more APNs. When a subscriber requests an APN that has been identified in a selected operator policy, then the set of commands in the associated APN profile will be applied. The same APN profile can be associated with multiple APNs and multiple operator policies. An APN profile groups a set of APN-specific parameters that may be applicable to one or more APNs. When a subscriber requests an APN that has been identified in a selected operator policy, the parameter values configured in the associated APN profile are applied. For example: Enable or disable a direct tunnel (DT) per APN (SGSN). Define charging characters for calls associated with a specific APN. Identify a specific GGSN to be used for calls associated with a specific APN (SGSN). Define various quality of service (QoS) parameters to be applied to calls associated with a specific APN. Restrict or allow PDP context activation on the basis of access type for calls associated with a specific APN. A single APN profile can be associated with multiple operator policies. To view APN profile properties in logical inventory: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory >local> Mobile > Profile > APN Profiles. The Vision client displays the list of APN profiles configured under the container. You can view the individual APN profile details from the table on the right pane or by choosing Logical Inventory > local> Mobile > Profile > APN Profiles > APN Profile.

The following list of characteristics configured for the APN profile are displayed: –PDP Inactivity Actions—Attributes related to PDP data inactivity. Once a data communication is in progress there are cases where this data communication can be inactive after some time, for example, when the user has locked the phone after browsing the internet or when the battery suddenly drains out. In such a case, the SGSN can take a configured action based on this inactivity. The inactivity timeout and the actions that can be taken based on certain conditions are modeled in this configuration. –QoS to DSCP Mapping (Downlink) / Qos to DSCP Mapping (Uplink)—Mapping of QoS parameters to DSCP. Configuration of the local values for the traffic class (TC) parameters for QoS configured for the APN. –PDP Restrictions (UMTS) / PDP Restrictions (GPRS)—Activation restrictions on PDP. Step 4Click each of one of these characteristics to view its properties on the right pane. See Table 27-121 for more details on the properties of each characteristics configured for the APN profile.
