Introduction In current D4 page 207 line 21: 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.

Motivate In page 207 line 28 states that The AAI-HO_CMD message should not include an ABS with cell bar information =1. In page 294 line 48 states that 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. In page 317 line 30 states that If the preferred ABS has Cell Bar bit=1 in its S-SFH, the AMS should re-select other ABS for network re-entry. In page 450 line 47 states that If Cell Bar bit = 1, this cell is not allowed for network entry or re-entry

Problem Statement To clean up the texts in the current D4. The AMS shall not perform HO, network entry or re-entry to a cell with Cell Bar bit=1 in its S-SFH.

Proposed Text [Modify the following text in section 16.2.6.3.2 “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.
