Section: 4.5.1.6 Call re-establishment
Content: The re-establishment procedure allows a MS to resume a connection in progress after a radio link failure, possibly in a new cell and possibly in a new location area. The conditions in which to attempt call re-establishment or not depend on the call control state, see subclause 5.5.4 and, whether or not a cell allowing call re-establishment has been found (as described in 3GPP TS 45.008[ None ]  [34]). MM connections are identified by their protocol discriminators and transaction identifiers: these shall not be changed during call re-establishment. The re-establishment takes place when a lower layer failure occurs and at least one MM connection is active (i.e. the mobile station's MM sublayer is either in state 6 "MM CONNECTION ACTIVE" or state 20 "WAIT FOR ADDITIONAL OUTGOING MM CONNECTION"). NOTE: During a re-establishment attempt the mobile station does not return to the MM IDLE state; thus no location updating is performed even if the mobile is not updated in the location area of the selected cell. No call re-establishment shall be performed for voice group and broadcast calls.
