Unique local identifier for the access point on the GGSN.
Status of a row in the access point table. This object is used to create or delete a conceptual row in this table.
To create a row, set this object to createAndGo. There are no mandatory objects in a create request.
To delete a row, set this object to destroy.
Access Point Name. The name consists of two parts:
The APN Network Identifier is mandatory and is a fully qualified domain name that conforms to the DNS naming conventions. An example of an APN Network Identifier would be: company.com.
The APN Operator Identifier is optional. It is a fully qualified domain name that conforms to the DNS naming convention and consists of three labels, the last of which must be .gprs. An example of an APN Operator Identifier would be: mncyyyy.mcczzzz.gprs.
An example of a full APN name with both the network and operator identifiers would be: company.com.mncyyyy.mcczzzz.gprs'.
This object would be a null string, if the name is not specified.
Type of access allowed to the PDN, through the access point. Access type can be:
Value |
Description |
transparent |
Users can access the PDN without authentication |
nontransparent |
Users must be authenticated by the GGSN |
Method by which a dynamic address is allocated for the access point. Allocation method can be:
Value |
Description |
global |
No method defined specifically for the access point. The DHCP or radius server that is globally configured for the GGSN is used to allocate the dynamic IP address for the user |
dhcp |
DHCP server is used to allocate the dynamic address to the user |
radius |
Radius server is used to allocate the dynamic address to the user |
disable |
Allocation of dynamic addresses is disabled |
IP address of the primary DHCP server from which a mobile subscriber can request for an IP address assignment to access the APN. In case the primary DHCP server is not available, the secondary DHCP server is used.
IP address of the secondary DHCP server. The secondary DHCP server is used if the primary DHCP server is not available.
DHCP gateway address that is used in the giaddr field of the DHCP request. The gateway address is used by DHCP to determine from the pool from which the IP address is allocated. If no DHCP gateway is specified, the IP address associated with the Gn interface is used.
Access list (ACL) that the GGSN uses to compare the packets received at the access point from the PDN for forwarding to an MS.
ACLs are used at the access point level to control access for packets between the APN and MS. Access violations by a packet, cause the packet to be either dropped or its PDP session terminated. The action to be taken is determined by the value of cgprsAccPtAccessViolation.
Access list (ACL) that the GGSN uses to compare packets that were originated by an MS and that were received at the access point for forwarding to the PDN.
ACLs are used at the access point level to control access for packets between the APN and MS. Access violations by a packet, cause the packet to be either dropped or its PDP session terminated. The action to be taken is determined by the value of cgprsAccPtAccessViolation.
Specifies how an access violation should be treated.
An access violation occurs if the IP packets violates any rules in the access list as specified by either cgprsAccPtIPAccListGroupIn or cgprsAccPtIPAccListGroupOut.
Access violations by packets are dealt with in one of two ways:
Value |
Action |
discardPacket |
Packets are discarded |
terminateSession |
User session is terminated |
Indicates if a user needs to subscribe to the access point before accessing it.
Indicates if network (PDN) initiated PDP sessions are allowed for the access point. If the value of the object is false, the PDP is initiated by the MS.
Dial-on-demand interface used to tunnel end-to-end PPP sessions from MS to external dial-up network.
Maximum number of consecutive seconds that the PDP context is allowed to have idle connection before the GTP session is terminated. A value of 0 means the session idle timer is not used.
Indicates if access to a roaming MS needs to be blocked for the APN.
Anonymous user name that is used by the GGSN when an MS tries to access a non-transparent APN without supplying user name and password.
Password corresponding to cgprsAccPtAnonymousUserName. For security reasons, retrieving this object returns a zero-length string.
Specifies if the ISDN id, used by the MS, needs to be suppressed when authenticating with a radius server.
This object can be set only if radius server is configured on the access point.
Value that is transmitted to the radius server in place of the mobile station's ISDN id. This object can be set only if cgprsAccPtMsIsdnIdSuppressed is true.
Valid characters for the object are 0 to 9, a, b, c, * and #. If no value is set for this object, then no MS-ISDN id is sent to the radius server.
AAA radius server group that is used for authentication by the APN.
AAA radius server group that is used for accounting by the APN. If no group is specified for accounting, cgprsAccPtAaaAuthServerGroup is used.
Used to enable accounting when the APN is in transparent mode. When the object is set to true, cgprsAccPtAaaAccountServerGroup is used for accounting. If cgprsAccPtAaaAccountServerGroup is not specified, cgprsAccPtAaaAuthServerGroup is used.
When the APN is in non-transparent mode, accounting is always enabled, that is, the object is true by default.
Type of APN. APN type can be:
Value |
Description |
virtual |
APN type that is not associated with any specific physical target network on the GGSN. When the object is set to virtual, all other APN parameters are ignored. |
real |
APN type that corresponds to a physical interface on a network that is external to the GGSN |
Name of the VRF with which the APN is associated.
Address space used by the dhcp server. This object can be set only if cgprsAccPtDHCPServerPri is set.
Enables GGSN to regenerate a PPP session for each IP PDP context on the APN.
Maximum number of regenerated PPP sessions allowed for the access-point. This object can be set only if cgprsAccPtPppRegenEnable is set to true.
Maximum tolerance time, in seconds, within which a regenerated PPP session has to fully come up. This object can be set only if cgprsAccPtPppRegenEnable is set to true.
Enables auto aggregation on the APN. When a user tries to configure entries in cgprsAccPtAggregTable, this object is automatically set to false. When the object is set to true, the entries in cgprsAccPtAggregTable, if any, are deleted.
