SCells are used to provide additional downlink and optionally uplink radio resources.

The network triggers the handover procedure e. Upon initiation of the procedure, the UE shall: That is, the response to the message used to activate security is not ciphered, while the subsequent messages e.

The PCell is 3631 to provide the security inputs and upper layer system information i. This Specification is provided for future development work within 3GPP only.

Normal measurement and mobility procedures are used to support handover to cells broadcasting a CSG identity. The source eNB should, for some time, maintain a context to enable the UE to return in case of handover failure. The UE applies the system information acquisition and change monitoring procedures for the PCell only. The segmentation is fixed for transmission of a given secondary notification within a cell i.

However, the UE only accepts a handover message when security has been activated. Following T expiry any dedicated preamble, if provided within the rach-ConfigDedicated, is not available for use by the UE anymore. Such RN-specific aspects are not applicable 33631 the UE.

In the case 3gppp a reference to a 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. The source eNB selects the target PCell. The handling of the radio bearers after the successful completion of the PDCP re-establishment, e. Upon receiving a change notification, the UE acquires the new system information immediately from the start of the next modification period.


The UE continues using the previously received system information until the new system information has been acquired. The source eNB transparently i. RRC integrity and ciphering are always activated together, i. The RRC states can further be 363331 as follows: Correspondingly, the UE initially considers lists to be empty e. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 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 segmentation is fixed for transmission of a given CMAS notification within a cell i. Lower layers discard RRC messages for which the integrity check has failed and indicate the integrity verification check failure to RRC.

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 target eNB decides which SCells are configured for use after handover, which may include cells other than the ones indicated by the source eNB.

The network may also initiate handover blindly, i. RRC handles the configuration of the security parameters which are part of the AS configuration: The individual contents of an information element are referred as fields. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR References are either specific identified by date of publication, edition number, version number, etc.

These general principles are illustrated in figure 3gop. One UE behaviour to be performed upon handover is specified, i.


The paging information is provided to upper layers, which in response may initiate RRC connection establishment, e. UEs may use systemInfoValueTag, e.

An RN 3ggpp with an RN subframe configuration does not need to apply the system information acquisition and change monitoring procedures. In addition to the state transitions shown in Figure 4. If the UE receives a Paging message including the systemInfoModification, it knows that the system information will change at the next modification period boundary. The AS applies three different security keys: The additional 3gpl is used to verify whether or not the UE is authorised to access the target PCell and may also be needed to identify handover candidate cell PCI confusion i.

The measurements are based on the time domain measurement resource restriction, if configured.

For further details see TS In this case, the target eNB should use the full configuration option to reconfigure the UE for Handover and Re-establishment. When DCI format 1C is used the maximum allowed by the physical layer is bits bytes while for format 366331 the limit is bits bytessee TS The number of warning messages that a UE can re-assemble simultaneously is a function of UE implementation. Blacklisted cells are not required to be reported.

Mathematical function used to ’round down’ i. The SI messages are transmitted within periodically 3pgp time domain windows referred to as SI-windows using dynamic scheduling.

Security mode command, failure The purpose of this procedure is to activate AS security upon RRC connection establishment.
