2. Introduction In current D4:
The AMS shall not perform HO to a cell with Cell Bar bit=1 in its S-SFH.
The “Cell Bar” bit, when set, indicates that an AMS should not perform network entry or re-entry to this cell.

3. Problem Statement To clean up the text in the current D4.
The AAI-HO_CMD message should not include an ABS with cell bar information =1.
If the AMS reads cell_bar=1 in SFH, this means this cell does not allow access of new AMS and the AMS shall select a different cell to restart network entry procedure.
The AMS shall not perform HO, network entry or re-entry to a cell with Cell Bar bit=1 in its S-SFH.

4. Proposed Text
[Modify the following text in section “HO decision and initiation”]
The AMS shall not perform HO, network entry or re-entry to a cell with Cell Bar bit=1 in its S-SFH. The “Cell Bar” bit, when set, indicates that an AMS should not perform network entry or re-entry to this cell.
