Manual

•
Sends Full/Partial RESET messages with the list of UEs associate to the MME and forwards to the
corresponding HeNBs.
Full/Partial Reset messages generated towards MME
•
If one of the HeNB association goes down, deletes all the UEs corresponding to HeNB.
•
Sends Partial RESET messages with the list of UEs corresponding to the HeNB and forwards to the
associated MMEs.
X2 Proxy Gateway support
As part of E-UTRAN architecture a X2 Gateways are deployed to allow the indirect X2-C interface between
(H)eNBS
The X2 GW hosts the following functions:
•
Routing the X2AP X2 MESSAGE TRANSFER message to target eNB or HeNB based on the routing
information received in the X2AP X2 MESSAGE TRANSFER message.
•
Informing the relevant (H)eNBs upon detecting that the signalling (i.e. SCTP) connection to a (H)eNB
is unavailable. The relevant (H)eNBs are the ones which had an "X2AP association" with this (H)eNB
via the X2 GW when the signalling connection became unavailable.
•
Mapping the TNL address(es) of a (H)eNB to its corresponding Global (H)eNB ID and maintaining the
association.
X2GW is implemented to support aggregation of both only X2-C interface.Note
