The embodiment of the present invention one provides a kind of resource seizing method, described resource seizing method is applicable to LTE, LTE Frequency Division Duplexing (FDD) (Frequency Division Duplex, abbreviation " FDD "), LTE time division duplex (Time Division Duplex, be called for short " TDD ") etc. in system, the embodiment of the present invention is not limited in any way this.

Particularly, as shown in Figure 1, its schematic flow sheet that is resource seizing method described in the embodiment of the present invention one, described resource seizing method can comprise the following steps:

Step 101: for arbitrary community, determine in described community wait the stock number of seizing carrying required release in described community while seizing successfully, wherein, described wait to seize be carried as the request access and because of the limited carrying that success accesses of local resource.

Particularly, in embodiment of the present invention, determine in order to improve the accuracy that takies resource, in order to reach the effect of the stability of a system when improving resource and seizing, in determining described community when seizing the stock number of carrying required release in described community while seizing successfully, load factor that usually can carrying described to be seized and the initial remaining load rate of described community are foundation; Certainly, it should be noted that, can also be according to other parameters, as described in the information such as ABR of community determine as described in community wait seize carrying while seizing successfully as described in the stock number of the required release in community, the embodiment of the present invention is not limited in any way this.

Particularly, for arbitrary carrying, as access bearer or carrying to be accessed (i.e. the carrying of request access community, comprise and wait to seize carrying), can, according to the information such as rate requirement, channel quality and system bandwidth of described carrying, estimate the load factor of this carrying; Particularly, in embodiment of the present invention, load factor of each carrying can be expressed as: the ratio of the Physical Resource Block of required distribution and total available physical resources piece of described community while meeting the rate requirement of described carrying.

Further, for arbitrary carrying to be accessed, when described carrying does not successfully access because local resource is limited, as the load factor of carrying as described in estimation be greater than as described in during the initial remaining load rate of community, can think the described carrying to be seized that is carried as to be accessed.

Further, in embodiment of the present invention, after the load factor of the carrying to be seized in obtaining described community, can determine the described stock number wait seizing carrying required release in described community while seizing successfully by following formula:

The load factor of described stock number wait seizing carrying required release in described community while seizing successfully=carrying described to be seized-(the access control load factor higher limit of described community-described community in respectively the load factor sum of access bearer).

That is to say, described wait seize carrying while seizing successfully the stock number of the required release in described community equal initial remaining load rate poor of the load factor of carrying described to be seized and described community; Wherein, each in the access control load factor higher limit that the initial remaining load rate of described community is described community and described community be the difference of the load factor sum of access bearer.

It should be noted that, in embodiment of the present invention, the access control load factor higher limit of described community can be adjusted setting according to actual conditions, and the embodiment of the present invention is not limited in any way this.

It should be noted that in addition, in embodiment of the present invention, determined described wait seize carrying while seizing successfully the stock number of the required release in described community normally described wait seizing carrying required stock number lower limit while seizing successfully, in follow-up resource is seized implementation, for the resource that guarantees carrying described to be seized is seized success rate, can be according to actual needs, on the determined described basis wait seizing carrying stock number lower limit of the required release in described community while seizing successfully, suitably raise, in order to discharge relatively sufficient local resource, the embodiment of the present invention is not limited in any way this.

Step 102: determine the changeable user terminal in described community.

Particularly, described user terminal can be mobile terminal, as mobile phone (or being called " honeycomb " phone) with there is the computer of mobile terminal, for example, can be portable, pocket, hand-hold type, mobile device built-in computer or vehicle-mounted etc., the embodiment of the present invention be limited in any way this.

Further, in embodiment of the present invention, for the arbitrary user terminal in described community, when determine described user terminal be 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 when seizing the preempting priority of carrying, can determine that described user terminal is changeable user terminal;

Wherein, for arbitrary user terminal, the preempting priority value of described user terminal is higher, and the preempting priority of described user terminal is lower;

The preempting priority value of described user terminal can calculate by following formula:

$P_j=\underset{i}{\overset{n}{\mathrm{\Σ}}}\frac{{\mathrm{\ρ}}_{\mathrm{ji}}}{\underset{i}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\ρ}}_{\mathrm{ji}}}\×P_{\mathrm{ji}};$

Wherein, P _jpreempting priority value for user terminal j; P _jiaRP preempting priority value (being generally the arbitrary numerical value in 1～14) for the corresponding access bearer of user terminal j i; ρ _jifor the load factor of the corresponding access bearer of user terminal j i, described i, j, n are more than or equal to 1 positive integer, and i is less than or equal to the number sum that the described n of n(is the corresponding access bearer of user terminal j).

It should be noted that in addition, in embodiment of the present invention, can be according to the RSRP(Reference Signal Receive Power of user terminal feedback, Reference Signal Received Power) value waits reference signal value, judge whether described user terminal is positioned at cell edge, as, when the RSRP value of described user terminal feedback is less than set point, can think that described user terminal is positioned at cell edge; Certainly, also can adopt other judgment modes of the prior art to determine whether described user terminal is positioned at cell edge, and the embodiment of the present invention is not limited in any way this.

Step 103: to determine that stock number sum that each changeable user terminal can discharge is not less than described when seizing the stock number of carrying the required release in described community while seizing successfully, according to preempting priority, order from low to high switches to other communities by each changeable user terminal successively, until after switching, resulting total releasing resource amount is not less than the described stock number wait seizing carrying required release in described community while seizing successfully.

Particularly, in embodiment of the present invention, for arbitrary changeable user terminal, due to when this changeable user terminal is carried out to handover operation, this changeable user terminal can be switched to other from the current service cell at this changeable user terminal place the Serving cell of service can be provided for this changeable user terminal, therefore, this changeable user terminal is carried out to the current business that handover operation can't interrupt this changeable user terminal, thereby can avoid the employing existed in prior art to force delivery mode to carry out when resource is seized the higher phenomenon of business cutting off rate caused, improve user's business experience.

Further, can adopt various handoff technique of the prior art to complete the handover operation of each changeable user terminal, the embodiment of the present invention is no longer repeated this.

Further, in embodiment of the present invention, when according to preempting priority, order from low to high is switched to other communities by each changeable user terminal successively, because the handover operation of each changeable user terminal needs the regular hour just can complete usually, and there is certain failed probability in handover operation, therefore, when carrying out the handover operation of each changeable user terminal, under the prerequisite that meets the delay requirement of setting, can carry out the trial switching of set point number, the embodiment of the present invention is not limited in any way this.

Further, (schematic flow sheet two that Fig. 2 is resource seizing method described in the embodiment of the present invention one) as shown in Figure 2, in embodiment of the present invention, seize success rate for the resource that guarantees carrying described to be seized, described method can also comprise the following steps:

Step 104: to determine that stock number sum that each changeable user terminal can discharge is less than described when seizing the stock number of carrying the required release in described community while seizing successfully, in the order from low to high after changeable user terminal switches to other communities by each successively according to preempting priority, determining describedly described community still needs the stock number discharged wait seizing carrying while seizing successfully.

Particularly, in this step 104, determinedly describedly wait seizing carrying, still need the stock number that discharges=described wait the stock number sum that stock number-each changeable user terminal can discharge of seizing carrying required release in described community while seizing successfully in described community while seizing successfully.

It should be noted that, in embodiment of the present invention, determinedly describedly wait seizing carrying, still need that the stock number that discharges is normally described still needs wait seizing when carrying is seized successfully the stock number lower limit discharged in described community while seizing successfully, the embodiment of the present invention is no longer repeated this.

Step 105: determine the access bearer that discharges in described community.

Particularly, for the arbitrary access bearer in described community, when determine described access bearer for the carrying that can be preempted (particularly, can determine according to the ARP parameter), and the preempting priority of definite described access bearer when seizing the preempting priority of carrying, determines that described access bearer is for can discharge access bearer lower than described.

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

Step 106: determining that each can discharge access bearer can discharge stock number sum and be not less than described when seizing carrying described community still needs the stock number of release while seizing successfully, according to preempting priority, order from low to high discharges successively each and can discharge access bearer, until carrying discharge after resulting total releasing resource amount be not less than the described stock number wait seizing carrying required release in described community while seizing successfully.

Particularly, after carrying described in this step 106 discharges, resulting total releasing resource amount refers to through the handover operation of changeable user terminal and after can discharging the releasing operation of access bearer, total releasing resource amount of resulting described community.

That is to say, carrying out resource while seizing, pay the utmost attention to the user terminal switchover policy, and when the inadequate resource discharged when switching, discharge strategy for waiting that seizing carrying provides enough resources in conjunction with forcing again, thereby, under the prerequisite of the current business of not interrupting to greatest extent user terminal, can be for the user provides preferably resource preempt-mode, thus the satisfaction and the application that have further improved the user are experienced.

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

Determining that each can discharge access bearer can discharge stock number sum and be less than describedly when seizing the carrying stock number that described community still needs to discharge while seizing successfully, does not discharge respectively and can discharge access bearer, and finish this resource and seize operation.

In the case, owing to but each releasing resource not being carried out the releasing operation of resource, thereby can further avoid problem in prior art, the problem includes: discharged but seized the user and do not seize and successfully wait the higher problem of cutting off rate caused in situation in resource, further improved user's satisfaction and experienced with application.

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

In the described technical scheme of the embodiment of the present invention one, owing to carrying out resource while seizing, pay the utmost attention to the user terminal switchover policy, and when carrying out the handover operation of changeable user terminal, can't interrupt the current business of user terminal, thereby can greatly reduce the cutting off rate of business, the satisfaction that improves the user and application and experience; And, owing to carrying out resource while seizing, the foundation that the load factor of usining is seized as resource, thereby can also improve and determine the accuracy that takies resource, and then reach the effect of the stability of a system when improving resource and seizing.

Have again, when the inadequate resource discharged when switching, discharge strategy for waiting that seizing carrying provides enough resources in conjunction with forcing again, thereby, under the prerequisite of the current business of not interrupting to greatest extent user terminal, for the user provides preferably resource preempt-mode, thereby further improved user's satisfaction and applied and experience.

Embodiment bis-:

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 respectively with A～G numbering, respectively access bearer is numbered with 1～10 respectively, and accessed user's terminal B, C, D comprise two access bearers respectively), and the access control load factor higher limit of supposing 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, each the precedence information of access bearer or carrying to be seized (comprise ARP preempting priority value and whether can be preempted etc.) can determine in advance by the ARP parameter, respectively the load factor of access bearer or carrying to be seized can be determined in advance according to the parameters such as rate requirement, average spectral efficiency (ase) (relevant with channel quality) and system bandwidth of each carrying, the RSRP value whether each accessed user's terminal can be fed back according to user terminal in cell edge is and definite in advance, and the embodiment of the present invention is no longer repeated this.

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

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

Step 201: determine in described community wait the stock number of seizing carrying required release in described community while seizing successfully.

Particularly, according to table 1 can calculate in described community each the load factor sum of access bearer be 0.88, and, because the access control load factor higher limit of pre-determined described community is 0.9, the load factor of carrying to be seized is 0.18, therefore, according to above condition can calculate described wait seize carrying while seizing successfully the stock number Reqld of the required release in described community be:

Reqld=0.18-（0.9-0.88）=0.16。

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

Particularly, can calculate the preempting priority value of each user terminal A～G by the formula in embodiment mono-(1), correspondingly, the preempting priority value of each the 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 (the preempting priority value is larger, and its corresponding preempting priority 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 definite 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 when seizing the preempting priority of carrying, can determine that described user terminal is changeable user terminal, therefore, determine that according to the preempting priority value of above-mentioned each user terminal A～G each parameter in result and table 1 is known, changeable user terminal in described community is user terminal B, C and E.

Correspondingly, according to preempting priority, (the 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, the preempting priority of the changeable user terminal that in table 2, position more keeps left is lower:

Table 2: changeable user terminal list

Changeable user terminal	B	E	C
				The 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 be switched.

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

Step 204: whether the judgement switching is successful, if, perform step 2051, otherwise, perform step 2052.

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

Particularly, after the user terminal handover success, can discharge corresponding local resource, therefore, can, after each handover success, upgrade the stock number of the required release in described community according to following formula:

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

Step 2052: judge whether to arrive and set time delay or whether switched set point number, if arbitrary result is yes, jump to step 207, otherwise,, after the switching of the user terminal that re-executes described not handover success, continue execution step 204.

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

Step 207: judge whether also to exist other changeable user terminals of not yet carrying out handover operation, if, perform step 208, otherwise, perform step 209.
