EMM Registered EMM Deregistered: Successful Attach and Tracking Area Update(TAU) procedures lead to transition to EMM-REGISTERED




24

MME load balancing: Since TA can belong to more than one MME, if oneMME is loaded then it is possible to send the paging message through other

MMEs

NetAct Optimizer supervises all registered cell relations between neighbouring LTE cells if they are stillvalid and reliable candidates to be a hand over destination. When the outcome results in an inefficient

neighbour relation the according cell relation may be blacklisted for handover (RL20)

SCTP: Stream Control Transmission Protocol

The resolution of PCI to IP-connectivity information is done by means of a PCI/RF/IP@ look-up tablestored at the eNB, provided by O&M-configuration (NetAct Optimizer, NetAct Configurator).

NetAct just provides in advance the mapping of IP@ to Physical Cell Ids.

•For UTRAN side, RU20 supports broadcasting LTE RF carriers information (as individual neighbour

information is not needed) in SIB19 to enable 3G4G cell reselection,, .
