As shown in figure 1, cell I and cell III are terrestrial cells, cell II is satellite cell, idea of the invention is that：It is false
If there is new calling access request in cell II, and there is no the available common signal channel of free time in cell II now, only specialized in and cut
Change the channel reservation for using.System can decide whether that channel reservation can be seized to receive this new calling according to the new strategy of this chapter
Access.Judging process is as follows, and shown in Fig. 2 is channel assignment procedures of the invention：
(1) when the new calling from terrestrial cells reaches satellite cell, satellite cell combines switching and arranges according to channel reservation
Team's strategy distribution channel, if be allocated successfully, the channel access for distributing is passed through to satellite cell by new calling, and new calling is accessed
Success, terminates this flow；Otherwise jump to step (2)；
(2) check in satellite cell whether there is available idle channel reservation, if it has, step (3) is then jumped to, otherwise
This new calling is rejected, and terminates this flow；
(3) calculate and to be switched to earliest in the pre-switch time of the user of satellite cell and satellite cell most in terrestrial cells
Early to be switched to the time difference of the pre-switch time of the user of terrestrial cells；
Position and velocity information according to user will be switched to the pre-cut of the user of satellite cell judging terrestrial cells
Change the time and satellite cell to be switched to terrestrial cells user the pre-switch time, respectively T11, T12, T13...T1mAnd T21,
T22, T23...T2m；
Calculate and to be switched to earliest in the pre-switch time of the user of satellite cell and satellite cell earliest in terrestrial cells
It is switched to the time difference of the pre-switch time of the user of terrestrial cells：Δ T=T1-T2；Wherein T1=min { T11, T12,
T13...T1m, T2=min { T21, T22, T23...T2m}；
(4) judge that whether the time difference Δ T in step (3), more than 0, if it is, jumping to step (8), otherwise, is redirected
To step (5)；As Δ T ＞ 0, before illustrating to have user to be switched in cell II in cell I, existing subscriber cuts in cell II
Change in cell III.So the channel reservation directly seized in cell II is given during this new calling access has no effect on cell I
The performance of handoffs of user；It is existing in cell I before illustrating to there is user to be switched in cell III in cell II when Δ T≤0
User is switched in cell II.The channel reservation that now can not directly seize in cell II, further be judged..
(5) available idle channel reservation number in statistics satellite cell；
(6) maximum pre-switch time and the satellite that the preceding n user of satellite cell is switched in calculating terrestrial cells are small
The time difference of the pre-switch time of the user of terrestrial cells is switched in area earliest；Wherein n is idle channel reservation number；
The preceding n user time respectively T ' that be switched in satellite cell in terrestrial cells11, T '12, T '13... T '1n；
Wherein n is idle channel reservation number；
Calculating will be switched in the maximum pre-switch time and satellite cell of the preceding n user of satellite cell in terrestrial cells
The time difference of the pre-switch time of the user of terrestrial cells is switched to earliest：Δ T '=T '1-T2, in formula, T '1=max { T '11,
T′12, T '13... T '1n, T2=min { T21, T22, T23...T2mFor the use of terrestrial cells is switched in satellite cell earliest
The pre-switch time at family；
(7) whether the time difference in step (6) is judged more than 0, if it is, step (8) is jumped to, otherwise, this calling
It is rejected；
(8) new calling is linked into satellite cell by idle channel reservation, new calling is successfully accessed.
Operation principle of the present invention：When a new calling be linked into up to when, system combines switching and arranges according to channel reservation first
Team's strategy calls distribution channel resource for this, if being allocated successfully, then this calling is accessed and starts communication using the resource got.But
It is, if failing to distribute channel for this access success according to channel reservation combination switching and queuing strategy, now to need confirmation small
Idle available channel reservation number in area, if without available channel reservation, this call congestion, if still available free
Channel reservation can be used, then the size according to Δ T judges whether this calling can seize reserved switching channel, if met by force
Condition is accounted for, then the channel that distribution is seized is called for this, access time calling；When have switching calling be linked into up to when, system is sentenced first
In disconnected Target cell whether available free available common signal channel, if it has, then switch for this calling distribute one it is available public
Channel, if it is not, judge whether available free available channel reservation, if it has, then switch calling distribution one for this can
Channel reservation, if it is not, continuing to judge, if there is converted channel reservation, if it has, then system can by force eventually
Only seize the communication most long of channel reservation time, the channel distribution that it is seized to time switching calling, if it is not, this time
Handover request will be rejected.
The available channel reservation that strategy seizes the free time using the pre-switch time is seized, a use for cell is not being influenceed
Alleviate new call blocking rate in the case of the switching of family.But because the user that channel reservation is seized in this cell is being switched to
During next cell, and existing user in this cell and indifference, so can go to compete same channel resource simultaneously, so meeting
Cause the performance of handoffs of this cell to decline, but influence very small, in tolerance interval.After strategy execution is seized, although sentence
Break and the calling of conversion channel reservation and do not interfere with a switching user for cell, but either new calling is accessed and still cut
It is all random to change calling and access, and just having can appear in before this community user is switched to next cell, and a upper cell is just
There is user to be switched to this cell, be at this moment accomplished by the communication that force termination seizes the user of channel reservation.Because this communication money
What is got inherently seized in source, but this is probability event, and this strategy still improves the new calling of system as a whole
Energy and resource utilization.
