[equation 2]: SLOT_CYCLE_INDEXs=

MAX[MIN_SLOT_CYCLE_INDEX _s，MIN(SLOT_CYCLE_INDEX _p，MAX_SLOT_CYCLE_INDEX _s)]。

This preferred slot cycle index (SLOT_CYCLE_INDEX _p) be the value of in portable terminal, storing, and have-4 to 7 preferred value.(SLOT_CYCLE_INDEX SIGN_SLOT_CYCLE_INDEX) should preferred slot cycle index (SLOT_CYCLE_INDEX by one or two field in registration message (RGM), originating information (ORM), page-response message (PRM) or end message message _p) value send to the base station.

Minimum slot cycle index (MIN_SLOT_CYCLE_INDEX _s) have a preferred value of-4 to 0.Maximum slot cycle index (MAX_SLOT_CYCLE_INDEX _s) have a preferred value of 0 to 7.Should maximum slot cycle index (MAX_SLOT_CYCLE_INDEX from the base station by system parameters message (SPM) or MC-RR parameter message (MCRRPM) _s) value send to portable terminal.

Utilize the hashing (Hashing) of the telephone number of portable terminal to obtain this paging time-slot (PGSLOT).Select a respective value from comprising 0 to the group of (C-1), wherein ' C ' is the paging time-slot periodic quantity of calculating by equation 1.Fig. 3 has illustrated preferred slot cycle index (SLOT_CYCLE_INDEX _p), maximum slot cycle index (MAX_SLOT_CYCLE_INDEX _s) and minimum slot cycle index (MIN_SLOT_CYCLE_INDEX _s) and paging time-slot (PGSLOT) be respectively 2 ,-1,3 and 6 situation.

Based on equation 2, selected slot cycle index (SLOT_CYCLE_INDEX _s) be ' 2 '.That is selected slot cycle index (SLOT_CYCLE_INDEX, _s) value be max[-1, min (2,3)], it equals ' 2 '.And based on equation 1, this paging time-slot cycle becomes 16 * 2 ², (that is slot cycle index (SLOT_CYCLE_INDEX, by calculating _s) value be applied as ' i ' ' 64 ').

Timeslot number from 0 to 2047 repeats.Therefore, as shown in Figure 3, because this paging time-slot cycle is 64, and this paging time-slot (PGSLOT) is 6, this portable terminal sequential monitoring timeslot number 6,70,134 and 198.

In the prior art of Xie Shiing, if portable terminal had before had data call, this data call is released in the above, then attempts to call out the time that this portable terminal must wait the whole cycle of inserting.Be necessary to set up parameter value separately, to reduce to receive the time delay of the paging that is used to call out access for specific portable terminal.This is to call out because the d/d portable terminal of setting up of calling is probably set up once more.

At present, use identical maximum slot cycle index (MAX_SLOT_CYCLE_INDEX with all portable terminals that same base is communicated by letter _s) and minimum slot cycle index (MIN_SLOT_CYCLE_INDEX _s).Therefore, attempt to set up when being connected, be used to receive from the shared time delay of the paging of this base station with the calling of base station when specific portable terminal.Therefore, need fast call establishing method and system.
