The mobile station updates internally stored information from the received message’s data fields. Configuration parameters and access parameters are received in the configuration messages and the Access Parameters Message or the Enhanced Access Parameters Message. The configuration messages on the Primary Broadcast Control Channel are: • ANSI-41 System Parameters Message • MC-RR Parameters Message • Universal Neighbor List Message • User Zone Identification Message • Private Neighbor List Message • Extended Global Service Redirection Message • Extended CDMA Channel List Message • Access Point Identification Message • Access Point Identification Text Message • Access Point Pilot Information Message • General Overhead Information Message • Flex Duplex CDMA Channel List Message • Alternative Technologies Information Message The configuration messages on the Paging Channel are: • System Parameters Message • Neighbor List Message • CDMA Channel List Message • Extended System Parameters Message • Global Service Redirection Message • Extended Neighbor List Message • General Neighbor List Message • User Zone Identification Message • Private Neighbor List Message • Extended Global Service Redirection Message • Extended CDMA Channel List Message • Access Point Identification Message • Access Point Identification Text Message • Access Point Pilot Information Message • General Overhead Information Message • Flex Duplex CDMA Channel List Message • Alternative Technologies Information Message Associated with the set of configuration messages sent on each Paging Channel or Primary Broadcast Control Channel is a configuration message sequence number (CONFIG_MSG_SEQ). When the contents of one or more of the configuration messages change, the configuration message sequence number is incremented. For each of the configuration messages received, the mobile station stores the configuration message sequence number contained in the configuration message (A41_SYS_PAR_MSG_SEQs, MC_RR_PAR_MSG_SEQs, SYS_PAR_MSG_SEQs, NGHBR_LST_MSG_SEQs, AP_PILOT_INFO_MSG_SEQs, EXT_NGHBR_LST_MSG_SEQs, GEN_NGHBR_LST_MSG_SEQs, UNI_NGHBR_LST_MSG_SEQs, CHAN_LST_MSG_SEQs, EXT_SYS_PAR_MSG_SEQs, GLOB_SERV_REDIR_MSG_SEQs, USER_ZONE_ID_MSG_SEQs, EXT_CHAN_LST_MSG_SEQs, FD_CHAN_LST_MSG_SEQs, EXT_GLOB_SERV_REDIR_MSG_SEQs, PRI_NGHBR_LST_MSG_SEQs, AP_IDT_MSG_SEQs, AP_ID_TEXT_MSG_SEQs, GOI_MSG_SEQs or ATIM_MSG_SEQs). The mobile station also stores the most recently received configuration message sequence number (CONFIG_MSG_SEQs) contained in any message (see 2.6.2.2.1, 2.6.2.2.3, 2.6.2.2.4, 2.6.2.2.5, 2.6.2.2.6, 2.6.2.2.7, 2.6.2.2.8, 2.6.2.2.9, 2.6.2.2.10, 2.6.2.2.11, 2.6.2.2.12, 2.6.2.2.13, 2.6.2.2.14, 2.6.2.2.17, 2.6.2.2.19, 2.6.2.2.20, 2.6.2.2.21, 2.6.2.2.22, 2.6.2.2.23, 2.6.2.2.24 and 2.6.2.3). The mobile station examines the stored values of the configuration message sequence numbers to determine whether the configuration parameters stored by the mobile station are current. The field EXT_SYS_PARAMETER in the System Parameters Message, when set equal to ‘0’, indicates that the base station is not sending the Extended System Parameters Message.

The configuration message sequence number is also included in the General Page Message and the Universal Page Message. This allows the mobile station to determine whether the stored configuration parameters are current without waiting for a configuration message. Access Parameters Messages or Enhanced Access Parameters Messages are independently sequence-numbered by the ACC_MSG_SEQ field. The mobile station stores the most recently received Access Parameters Message or Enhanced Access Parameters Messages sequence number (ACC_MSG_SEQs). Paging Channels, Broadcast Control Channels, and Forward Common Control Channels shall be considered different if they are transmitted by different base stations, if they are transmitted on different code channels, or if they are transmitted on different CDMA Channels. Configuration and access parameters from one Paging Channel or Primary Broadcast Control Channel shall not be used while monitoring a different Paging Channel or Primary Broadcast Control Channel/Forward Common Control Channel except for registration and authentication parameters while the mobile station is performing an access probe handoff or access handoff. The mobile station shall ignore any overhead message whose PILOT_PNr field is not equal to the pilot offset index (PILOT_PNs) of the base station whose Paging Channel or Primary Broadcast Control Channel is being monitored. The mobile station may store the configuration parameters from Paging Channels or Primary Broadcast Control Channel it has recently monitored. When a mobile station starts monitoring a Paging Channel or a Primary Broadcast Control Channel/Forward Common Control Channel that it has recently monitored, the mobile station can determine whether the stored parameters are current by examining the CONFIG_MSG_SEQs in a configuration message or a page message. The mobile station shall use a special value, NULL, to be stored in place of sequence numbers for messages that have not been received or are marked as not current. The special value NULL shall be unequal to any valid message sequence number. The mobile station shall consider the stored configuration parameters to be current only if all of the following conditions are true: • If the mobile station is monitoring the Paging Channel, the following stored configuration message sequence numbers (SYS_PAR_MSG_SEQs, NGHBR_LST_MSG_SEQs, EXT_NGHBR_LST_MSG_SEQs, CHAN_LST_MSG_SEQs, EXT_SYS_PAR_MSG_SEQs, GEN_NGHBR_LST_MSG_SEQs, AP_IDT_MSG_SEQs, AP_ID_TEXT_MSG_SEQs, USER_ZONE_ID_MSG_SEQs, PRI_NGHBR_LST_MSG_SEQs, EXT_CHAN_LST_MSG_SEQs, EXT_GLOB_SERV_REDIR_MSG_SEQs and GLOB_SERV_REDIR_MSG_SEQs) are equal to CONFIG_MSG_SEQs; and • If the mobile station is monitoring the Forward Common Control Channel/ Primary Broadcast Control Channel, the following stored configuration message sequence numbers (A41_SYS_PAR_MSG_SEQs, MC_RR_PAR_MSG_SEQs, UNI_NGHBR_LST_MSG_SEQs, AP_IDT_MSG_SEQs, AP_ID_TEXT_MSG_SEQs, USER_ZONE_ID_MSG_SEQs, PRI_NGHBR_LST_MSG_SEQs, EXT_CHAN_LST_MSG_SEQs, FD_CHAN_LST_MSG_SEQs, and EXT_GLOB_SERV_REDIR_MSG_SEQs) are equal to CONFIG_MSG_SEQs; and • If the mobile station supports flexible spacing between forward and reverse channels, stored configuration message sequence number FD_CHAN_LST_MSG_SEQs is equal to CONFIG_MSG_SEQs; and • CONFIG_MSG_SEQs is not equal to NULL; and • No more than T31m seconds (see Annex D) have elapsed since the mobile station last received a valid message on the Paging Channel or the Primary Broadcast Control Channel/Forward Common Control Channel for which the parameters were stored. If the configuration parameters are not current, the mobile station shall process the stored parameters upon receipt of the configuration messages as described in 2.6.2.2.1, 2.6.2.2.3, 2.6.2.2.4, 2.6.2.2.5, 2.6.2.2.6, 2.6.2.2.7, 2.6.2.2.8, 2.6.2.2.9, 2.6.2.2.10, 2.6.2.2.11, 2.6.2.2.12, 2.6.2.2.13, 2.6.2.2.14, 2.6.2.2.17, 2.6.2.2.19, 2.6.2.2.20, 2.6.2.2.21, 2.6.2.2.22, 2.6.2.2.23 and 2.6.2.2.24.
