| 1. In a radio access network (RAN), a method comprising:
detecting a first threshold level of occupancy of a paging channel and responsively switching the RAN to a first state in
which the RAN (i) allows at least initial transmission of a first type of paging messages, (ii) blocks retransmission of the
first type of paging messages, and (iii) allows retransmission of a second type of paging messages; and
detecting a second threshold level of occupancy of the paging channel and responsively switching the RAN to a second state
in which the RAN (i) allows at least initial transmission of the first type of paging messages and the second type of paging
messages, and (ii) blocks retransmission of the first type of paging messages and the second type of paging messages,
wherein the first threshold level is different than the second threshold level,
wherein the first type of paging messages is selected from the group consisting of (i) direct paging messages, (ii) feature
notification paging messages, (iii) data burst paging messages, (iv) data burst paging messages to communicate short message
service (SMS) messages, (v) channel assignment paging messages, (vi) general paging messages, (vii) broadcast paging messages,
(viii) broadcast paging messages comprising a system parameter message, and (ix) broadcast paging messages comprising a neighbor
list message,
wherein the second type of paging messages is selected from the group consisting of (i) direct paging messages, (ii) feature
notification paging messages, (iii) data burst paging messages, (iv) data burst paging messages to communicate short message
service (SMS) messages, (v) channel assignment paging messages, (vi) general paging messages, (vii) broadcast paging messages,
(viii) broadcast paging messages comprising a system parameter message, and (ix) broadcast paging messages comprising a neighbor
list message, and
wherein the selected first type of paging messages is different than the selected second type of paging messages.
