HeNB Gateway in Wireless LTE Network
Additionally, if archiving of the collected statistics is desired, the Bulk Statistics server writes the files to an alternative
directory on the server. A specific directory can be configured by the administrative user or the default directory can be
used. Regardless, the directory can be on a local file system or on an NFS-mounted file system on the Web Element
Manager server.

DSCP Marking on S1-U Relay

Cisco supports the DSCP marking of S1-U traffic traversing the HeNB-GW. This functionality on HeNB-GW is
supported through command line interface (CLI). CLI configuration capability has been enabled for DSCP marking for
both Access and Network service.
CLIs are used for the dscp marking configuration for IP packets sent out on the S1-U interface, from the HeNB-GW to
the Access/Network side. Default value used for dscp marking is the dscp value for the incoming packet.
Important:

Fault Reporting Support

SNMP traps are used for faults and fault reporting in the system for network side S1-MME and S1-U interfaces. For
these traps on the network side, some other mechanism is required, as the SCTP/S1-MME associations do not generate
SNMP traps.

Location Reporting Support

Cisco HeNB-GW supports the location reporting feature for the subscribers/UE movements.
Location Reporting is the procedure by which the serving MME keeps in the track of the UE change in location within
the allowed tracking area list of the eNodeB.
With the HeNBGW deployed in the Femtocell LTE network, MME does not direct connect to HeNBs, and therefore
any location report message is forwarded by the HeNB-GW to and fro. When HeNB-GW receives location reporting
control message with local eNodeB ID and remote MMEUE S1AP id, HeNB-GW forwards the same to the appropriate
HeNB by replacing it with remove ENB ID and local MME UE s1AP ID.

QoS Support

Cisco HeNB-GW along with the SeGW supports QoS handling based on the DSCP mapping configuration.
QoS support provides a foundation for contributing towards improved Quality of User Experience (QoE) by enabling
deterministic end-to-end forwarding and scheduling treatments for different services or classes of applications pursuant
to their requirements for committed bandwidth resources, jitter and delay. In this way, each application receives the
service treatment that users expect.

Redundancy Support

To support redundancy, the HeNB-GW tasks should be started based on the following guidelines:
