NAS dedicated information transfer, UE capability transfer, sub-clause 5. In order to avoid such re-use, the eNB may e. There may be multiple SI messages transmitted with the same periodicity. The number of warning messages that a UE can re-assemble simultaneously is a function of UE implementation. The SI messages are transmitted within periodically occurring time domain windows referred to as SI-windows using dynamic scheduling.
Commercial Mobile Alert System: The MIB includes a limited number of most essential and most frequently transmitted parameters that are needed to acquire other information from the cell, and is transmitted on BCH.
In addition to the state transitions shown in Figure 4. The PCell is used to provide the security inputs and upper layer system information i. Upon receiving a change notification, the UE acquires the new system information immediately from the start of the next modification period.
Normal measurement and mobility procedures are used to support handover to cells broadcasting a CSG identity. The UE may apply above failure handling also in case the RRCConnectionReconfiguration message causes a protocol error for which the generic error handling as defined in 5.
No AS-parameters are exchanged to serve as inputs for the derivation of the new AS keys at connection establishment.
Performs logging of available measurements together with location and time for logged measurement configured UEs. The present document has not been subject to any approval process by the 3GPP Organizational Partners and shall not be implemented. The scope of the present document also includes: The network may also initiate handover blindly, i. The AS applies three different security keys: When DCI format 1C is used the maximum allowed by the physical layer is bits bytes while for format 1A the limit is bits bytessee TS One UE behaviour to be performed upon handover is specified, i.
In downlink piggybacking of NAS messages is used only for one dependant i. The segmentation is fixed for transmission of a given CMAS notification within a cell i. The individual contents of an information element are referred as fields. These general principles are illustrated in figure 5. System information may be transmitted a number of times with the same content within a modification period, as defined by its scheduling.
The integrity and ciphering of the RRC message used to perform handover is based on the security configuration used prior to the handover and is performed by the source eNB.
This connection resumption succeeds only if the accessed cell is prepared, i. Security mode command, failure The purpose of this procedure is to activate AS security upon RRC connection establishment. The details of the CDMA state models are out of the scope of this specification.

In the case of a reference to 363331 3GPP document including a GSM documenta non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
In addition sub-clause 5. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval.
Such RN-specific aspects are not applicable to the UE. If no paging message is received by the UE during a modification period, the UE may assume that no change of system information will occur at the next modification period boundary.
The source eNB should, for some time, maintain a context to enable the UE to return in case of handover failure. Further details about the services provided by Packet Data Convergence Protocol layer e. However, the UE only accepts a handover message when security has been activated. This specification is organised as follows: If the UE receives a Paging message including the systemInfoModification, it knows that the system information will change at the next modification period boundary.
At each point in time, the UE keeps a single value for each field except for during handover when the UE temporarily stores the previous configuration so it can revert back upon handover failure.
The RRC states can further be characterised as follows: For further details see TS The services provided by Radio Link Control layer e. More specifically, the following three SRBs are defined: Further details about the services provided by Medium Access Control layer e.
The RRC messages to activate security 336331 and successful response are integrity protected, while ciphering is started only after completion of the procedure. The source eNB selects the target PCell.
The source eNB transparently i. The physical layer imposes a limit to the maximum size a SIB can take. The measurements are based on the time domain measurement resource restriction, if configured. Full configuration option includes an initialization of the radio configuration, which makes the procedure independent of the configuration used in the source cell s with the exception that the security algorithms are continued for the RRC re-establishment.
The UE shall continue cell re-selection related 3ypp as well as cell re-selection evaluation. The UE acquires the detailed time-domain scheduling and other information, e.
