Condition<br />

Explanation<br />

This IE is mandatory present if the IE "Protocol error<br />

indicator" is included and has the value TRUE.<br />

Otherwise it is not needed.<br />

NOTE1: To facilitate that network nodes can transparently forward the RRC information received, the INTER<br />

RAT HANDOVER INFO WITH INTER RAT CAPABILITIES should include the entire INTER RAT<br />

HANDOVER INFO message. The network node, which may not be able to decode the information<br />

received, may only append some information to what was received.<br />

NOTE2: The above table does not need to reflect the order of the information elemen<strong>ts</strong> in the actual encoded<br />

message. The order, that is reflected in the ASN.1, should be chosen in a manner that avoids that network<br />

nodes need to perform reordering of information elemen<strong>ts</strong>.<br />

14.12.4.2 SRNS RELOCATION INFO<br />

This RRC message is sent between network nodes when preparing for an SRNS relocation or a handover/cell<br />

reselection from GERAN Iu mode.<br />

With the presence or absence of the IE "RB identity for Hard Handover message" the source RNC indicates to the target<br />

SRNC whether the source RNC expec<strong>ts</strong> to receive the choice "DL DCCH message" in the IE "RRC information, target<br />

RNC to source RNC" in case the SRNS relocation is of type "UE involved". Furthermore the target RNC uses this<br />

information for the calculation of the MAC-I.<br />
