The further details are specified in TS System information may be transmitted a number of times with the same content within a modification period, as defined by its scheduling.
Although the UE may be informed about changes in system information, no further details are provided e. This Specification is provided for future development work within 3GPP only.
The cell in which the re-establishment procedure succeeds becomes the PCell while SCells, if configured, are released. In this case, the target eNB should use the full configuration option to reconfigure the UE for Handover and Re-establishment. Performs logging of available measurements together with location and time for logged measurement configured UEs. The RRC states can further be characterised as follows: In downlink piggybacking of NAS messages is used only for one dependant i.
However, the UE needs to perform system information acquisition upon cell re-selection. The SI messages are transmitted within periodically occurring time domain windows referred to as SI-windows using dynamic scheduling. Additionally, the UE considers stored system information to be invalid after 3 hours from the moment it was successfully confirmed as valid, unless specified otherwise.
A term defined in the present document takes precedence over the definition of the same term, if any, in TR The source eNB transparently i. Unless explicitly stated otherwise in 36331 procedural specification, the system information acquisition procedure overwrites any stored system information, i.
Before sending the handover message to 3g;p UE, the source eNB prepares one or more target cells. 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 3gpo through the system information acquisition procedure.
The ciphering algorithm is common for all radio bearers i. Further details about the services provided by Medium Access Control layer e. Commercial Mobile Alert System: NAS dedicated information transfer, UE capability transfer, sub-clause 5.
Radio configuration 63331 not just the resource configuration but includes other configurations like MeasConfig and OtherConfig. 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.
Mathematical function used to ’round down’ i.
RRC integrity and ciphering are never de-activated. One UE behaviour to be performed upon handover is specified, i. Neither integrity protection nor ciphering applies for SRB0. A structural element containing a single or multiple fields is referred as information element.
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.
No AS-parameters are exchanged to serve as inputs for the derivation of the new AS keys at connection establishment.
The UE applies the system information acquisition and change monitoring procedures for the PCell only. Such RN-specific aspects are not applicable to the UE. Upon initiation of the procedure, the UE shall: Segmentation can be applied for the delivery of a secondary notification. 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.
More specifically, the following three SRBs are defined: If the UE is unable to comply with part of the configuration, it does not apply any part of the configuration, i. The copyright and the foregoing restriction extend to reproduction in all media. An RN configured with an RN subframe configuration does not need to apply the system information acquisition and change monitoring procedures.
The handling of the radio bearers after the successful completion of the PDCP re-establishment, e. If the conditions for cell re-selection are fulfilled, the UE shall perform cell re-selection as specified in 5.
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. Upon successful completion of the handover, the UE sends a message used to confirm the handover.
