If the mobile station receives a broadcast page containing a burst type and broadcast address for a Data Burst Message that the mobile station has been configured to receive (see 2.6.2.3), the mobile station should monitor the slot in which the corresponding broadcast Paging Channel message will be sent, determined as follows:

• The mobile station shall consider a broadcast page to have been received in the paging slot in which the General Page Message containing the broadcast page began.

• If BCAST_INDEX_s is not equal to ‘000’, the paging slot containing the broadcast page is defined as the reference slot.

• Let n represent the ordinal number of the broadcast page relative to other broadcast pages that are contained in the same General Page Message (n = 1, 2, 3,…). The mobile station should monitor the Paging Channel slot that occurs n  3 paging slots after the reference slot.

After receiving a broadcast message or a broadcast page for a Data Burst Message and a corresponding broadcast Paging Channel message when BCAST_INDEX_s is not equal to ‘000’, the mobile station should discard all further broadcast pages and all further broadcast Paging Channel messages containing the same BURST_TYPE and BC_ADDR fields that are received within 4  (B + 3) paging slots of the first paging slot in the broadcast paging cycle in which the broadcast page or broadcast message was first received. (B + 3 is the duration of the broadcast paging cycle as defined in 2.6.2.1.1.3.3).

After receiving a broadcast message or a broadcast page for a Data Burst Message and a corresponding broadcast Paging Channel message when BCAST_INDEX_s is equal to ‘000’, the mobile station should discard all further broadcast pages and all further broadcast Paging Channel messages containing the same BURST_TYPE and BC_ADDR fields that are received within 16  2^{MAX_SLOT_CYLCE_INDEXs} slots of the paging slot in which the broadcast page or broadcast message was first received.
