9.4.19.1 Full name for network
This IE may be sent by the network. If this IE is sent, the contents of this IE indicate the "full length name of the network" that the network wishes the mobile station to associate with the MCC and MNC contained in the routing area identification of the current cell.
9.4.19.2 Short name for network
This IE may be sent by the network. If this IE is sent, the contents of this IE indicate the "abbreviated name of the network" that the network wishes the mobile station to associate with the MCC and MNC contained in the routing area identification of the cell the MS is currently in.
9.4.19.3 Network time zone
This IE may be sent by the network. The mobile station should assume that this time zone applies to the routing area of the cell the MS is currently in.
9.4.19.4 Universal time and time zone
This IE may be sent by the network. The mobile station should assume that this time zone applies to the routing area the MS is currently in. The mobile station shall not assume that the time information is accurate.
9.4.19.5 LSA Identity
This IE may be sent by the network. The contents of this IE indicate the LSA identity of the serving cell.
