Paging Procedure
Paging is initiated when there is data to be sent to an idle UE to trigger a service request from the UE. Once the UE
reaches connected state, the data is forwarded to it.
Paging retransmission can be controlled by configuring a paging-timer and retransmission attempts on system.
Subscriber Session Processing
This section provides information on how LTE/SAE subscriber data sessions are processed by the system MME. The
following procedures are provided:
User-initiated Transparent IP:
An IP EPS Bearer context request is received by the MME from the UE for a
PDN. The subscriber is provided basic access to a PDN without the MME authenticating the subscriber. Either
a static or dynamic IP address can be assigned to the MS in this scenario.
User-initiated Non-transparent IP:
An IP EPS Bearer context request is received by the MME from the UE for
a PDN. The MME provides subscriber authentication services for the data session. Either a static or dynamic IP
address can be assigned to the MS in this scenario.
Network-initiated:
An IP EPS Bearer context request is received by the MME from the PDN for a specific
subscriber. If configured to support network-initiated sessions, the MME, will initiate the process of paging the
MS and establishing a EPS Bearer context.
Subscriber Registration Setup Procedure
The following figure and the text that follows describe the message flow for a successful user-initiated subscriber
registration setup procedure.
