Particularly, in this step 104, described in determined in time seizing carrying and seize successfully described community still need the stock number that discharges=described in stock number-each changeable user terminal of the required release in described community in time seizing carrying and seize successfully stock number sum that can discharge.

It should be noted that, in embodiment of the present invention, described in determined wait seize carrying seize successfully time described community still need discharge stock number normally described in wait seize carrying seize successfully time still need discharge stock number lower limit, the embodiment of the present invention no longer repeats this.

Step 105: determine to discharge access bearer in described community.

Particularly, for the arbitrary access bearer in described community, described in determine access bearer be the carrying that can be preempted (particularly, can determine according to ARP parameter), and described in determining the preempting priority of access bearer lower than described in time seizing the preempting priority of carrying, described in determining access bearer for access bearer can be discharged.

Wherein, described in determine the ARP preempting priority value of access bearer higher than the ARP preempting priority value of carrying described to be seized, or, when described in determining the ARP preempting priority value of access bearer equal described in wait described in the load factor of the ARP preempting priority value and described access bearer of seizing carrying is greater than in time seizing the load factor of carrying, described in can determining the preempting priority of access bearer lower than the preempting priority of carrying described to be seized.

Step 106: determine respectively can to discharge stock number sum that access bearer can discharge be not less than described in time seizing carrying and seize successfully, described community still needs the stock number discharged time, discharge successively according to preempting priority order from low to high and respectively can discharge access bearer, until after carrying release total releasing resource amount of obtaining be not less than described in the stock number of the required release in described community in time seizing carrying and seize successfully.

Particularly, the total releasing resource amount obtained after carrying described in this step 106 release refer to through changeable user terminal handover operation and can discharge access bearer releasing operation after, total releasing resource amount of the described community obtained.

That is, when carrying out resource and seizing, pay the utmost attention to user terminal switchover policy, and when switching the inadequate resource of release, enough resources are provided, thus, under the prerequisite of current business of not interrupting user terminal to greatest extent for waiting to seize to carry again in conjunction with forcible aborting strategy, preferably resource preempt-mode can be provided for user, thus further increase satisfaction and the application experience of user.

Further, in embodiment of the present invention, described method can also comprise the following steps:

Determine respectively can to discharge stock number sum that access bearer can discharge be less than described in time seizing carrying and seize successfully, described community still needs the stock number discharged time, do not discharge and respectively can discharge access bearer, and terminate this resource and seize operation.

In the case, due to not to respectively carrying out the releasing operation of resource by releasing resource, thus can avoid problem in prior art further, the problem includes: discharged in resource but seized the higher problem of the cutting off rate that causes under user does not seize the situation such as successfully, the satisfaction further increasing user is experienced with application.

The embodiment of the present invention one provides a kind of resource seizing method, described method comprises: for arbitrary community, the stock number determining the required release in described community in time seizing carrying and seize successfully in described community and the changeable user terminal determining in described community, and determine stock number sum that each changeable user terminal can discharge be not less than described in discharge needed for described community in time seizing carrying and seize successfully stock number time, successively each changeable user terminal is switched to other communities according to preempting priority order from low to high, until after switching total releasing resource amount of obtaining be not less than described in the stock number of the required release in described community in time seizing carrying and seize successfully, wherein, described wait to seize be carried as request access and because of the carrying of the limited unsuccessful access of local resource.

Embodiment two:

Below in conjunction with specific embodiment, resource seizing method described in the embodiment of the present invention one is described further.

Suppose that each accessed user's terminal in community/essential information of access bearer is as shown in table 1 (wherein, each accessed user's terminal is numbered with A ~ G respectively, each access bearer is respectively by 1 ~ 10 numbering, and accessed user terminal B, C, D comprise two access bearers respectively), and the access control load factor higher limit of hypothesis community is 0.9, the load factor demand of carrying to be seized is 0.18, and the ARP preempting priority value of carrying to be seized is 5.

It should be noted that, the precedence information (comprise ARP preempting priority value and whether can be preempted) of each access bearer or carrying to be seized is determined in advance by ARP parameter, the load factor of each access bearer or carrying to be seized can be determined in advance according to parameters such as the rate requirement of each carrying, average spectral efficiency (ase) (relevant with channel quality) and system bandwidths, whether each accessed user's terminal is in cell edge can be determined in advance according to the RSRP value of user terminal feedback, and the embodiment of the present invention no longer repeats this.

Table 1: community accessed user's terminal/access bearer basic condition

Correspondingly, as shown in Figure 3 (Fig. 3 is the schematic flow sheet of resource seizing method described in the embodiment of the present invention two), described resource seizing method can comprise the following steps:

Step 201: the stock number determining the required release in described community in time seizing carrying and seize successfully in described community.

Particularly, the load factor sum of each access bearer that can calculate in described community according to table 1 is 0.88, and, due to the access control load factor higher limit of pre-determined described community be 0.9, the load factor of carrying to be seized is 0.18, therefore, can calculate according to above condition described in time seizing carrying and seize successfully the stock number Reqld that discharges needed for described community be:

Reqld=0.18-（0.9-0.88）=0.16。

Step 202: determine the changeable user terminal in described community, and according to preempting priority order from low to high, each changeable user terminal is sorted.

Particularly, calculate the preempting priority value of each user terminal A ~ G by the formula (1) in embodiment one, correspondingly, the preempting priority value of each user terminal A ~ G calculated is respectively 8,7.4,6.6,8.7,7,10 and 3; And, because the ARP preempting priority value of carrying described to be seized is 5, therefore known, the preempting priority of user terminal A, B, C, D, E and F is all lower than the priority (preempting priority value is larger, and the preempting priority corresponding to it is lower) of carrying described to be seized.

Further, due in embodiment of the present invention, for the arbitrary user terminal in described community, when determining that described user terminal is positioned at described cell edge, and determine preempting priority that described user terminal comprises at least one access bearer that can be preempted and described user terminal lower than described in time seizing the preempting priority of carrying, can determine that described user terminal is changeable user terminal, therefore, according to each parameter in the preempting priority value determination result of above-mentioned each user terminal A ~ G and table 1, changeable user terminal in described community is user terminal B, C and E.

Correspondingly, according to preempting priority, (preemptive priority value of series is larger from low to high, preempting priority is lower) tactic each changeable user terminal list can be as shown in table 2, wherein, in table 2, the preempting priority of the changeable user terminal that position more keeps left is lower:

Table 2: changeable user terminal list

Changeable user terminal	B	E	C
				Preempting priority value	7.4	7	6.6
Load factor	0.15	0.04	0.14

Step 203: select the minimum changeable user terminal of preempting priority to switch.

Particularly, in embodiment of the present invention, according to the determination result of step 202 or table 2 known, the preempting priority of user terminal B is minimum, therefore, can preferentially switch user terminal B.

Step 204: judge that whether switching is successful, if so, then perform step 2051, otherwise, perform step 2052.

Step 2051: the stock number upgrading the required release in described community, and perform step 206.

Particularly, after user terminal handover success, corresponding local resource can be discharged, therefore, after each handover success, the stock number discharged needed for described community can be upgraded according to following formula:

The stock number of the required release in the described community after renewal=described in the changeable user terminal of the stock number-handover success of the required release in described community discharges in time seizing carrying and seize successfully stock number sum.

Step 2052: judge whether arrive setting time delay or whether switch set point number, if arbitrary result is yes, then jump to step 207, otherwise, then after the switching of the user terminal of handover success non-described in re-executing, continue to perform step 204.

Step 206: judge whether to discharge enough local resources, if so, then terminates this resource and seizes operation (resource is seized successfully), otherwise, perform step 207.

Step 207: judge whether also to exist other the changeable user terminals not yet performing handover operation, if so, then performs step 208, otherwise, perform step 209.
