However, the UE needs to perform system information acquisition upon cell re-selection. Commercial Mobile Alert System: The further details are specified in TS The RRC states can further be characterised as follows: Neither integrity protection nor ciphering applies for SRB0.
This specification 3gpl organised as follows: In addition sub-clause 5.

Additionally, the UE considers stored 3631 information to be invalid after 3 hours from 3ypp moment it was successfully confirmed as valid, unless specified otherwise. NAS dedicated information transfer, UE capability transfer, sub-clause 5. The integrity and ciphering algorithms can only be changed upon handover.
However, the UE only accepts a handover message when security has been activated. The UE acquires the detailed time-domain scheduling and other information, e. The Organizational Partners accept no liability for any use of this Specification. The segmentation is fixed for transmission of a given secondary notification within a cell i. Before sending the handover message to the UE, the source eNB prepares one or more target cells.
The additional information 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 present document has not been subject to any approval process by the 3GPP Organizational Partners and shall not be implemented.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document. The paging information is provided to upper layers, which in response may initiate RRC connection establishment, e.
Unless explicitly stated otherwise in the procedural specification, the system information acquisition procedure overwrites any stored system information, i. In order to avoid such re-use, the eNB may e.
More specifically, the following three SRBs are defined: The PCell is used to provide the security inputs and upper layer system information i.

Segmentation can be applied for the delivery of a CMAS notification. A structural element containing a single or multiple fields is referred as information element. Radio configuration is not just the resource configuration but includes other configurations like MeasConfig and OtherConfig. The modification period is configured by system information. The services provided by physical layer e.
The SI messages are transmitted within periodically occurring time domain windows referred to as SI-windows using dynamic scheduling.
References are either specific identified by date of publication, edition number, version number, etc. However, it is possible to switch to a ‘NULL’ ciphering algorithm eea0. The UE continues using the previously received system information until the new system information has been acquired. When the network changes some of the system information, it first notifies the UEs about this change, i.
The source eNB transparently i. Only in exceptional cases, as specified within this specification, TS For RNs configured with an RN subframe configuration, the system information contained in this dedicated signalling replaces any corresponding stored system information and takes precedence over any corresponding system information acquired through the system information acquisition procedure.
