In the embodiment of the present invention, the method of the utilization rate of air interface resource that the statistics any community of current time, base station is corresponding is: take current time as starting point, the Physical Resource Block number that in Preset Time length before the statistics current time of base station, above-mentioned any community has been used, and above-mentioned any community available physical resources piece total number in this Preset Time length; Calculate the Physical Resource Block number that any community of above-mentioned statistics used and the ratio of this available physical resources piece total number, utilization rate of air interface resource corresponding to above-mentioned any community using this ratio as current time.Wherein, above-mentioned available physical resources piece total number comprises the above-mentioned Physical Resource Block number used.

The utilization rate of air interface resource of any community of this that will obtain in said process and default threshold value compare, when above-mentioned utilization rate of air interface resource is greater than default threshold value, according to the channel quality parameter of at least one carrying to be accessed, obtain the Service Quality Metrics of at least one carrying to be accessed; Otherwise, be Service Quality Metrics weighted factor assignment, and obtain the Service Quality Metrics of at least one carrying to be accessed according to formula one.Wherein, above-mentioned default threshold value can set in advance according to concrete network application situation, and preferably, this default threshold value is 70%～90%.

In the embodiment of the present invention, channel quality parameter according at least one carrying to be accessed, the process of obtaining the Service Quality Metrics of at least one carrying to be accessed is: base station, according to the channel quality parameter of above-mentioned at least one carrying to be accessed, obtains the Service Quality Metrics weighted factor of this at least one carrying to be accessed; Obtain the rate requirement information of carrying in above-mentioned access request message, based on this rate requirement information, obtain the load factor increment of this at least one carrying to be accessed; Obtain respectively the rate requirement information of the access bearer that each accessed user's equipment corresponding to the above-mentioned any community of current time is corresponding, each rate requirement information of access bearer based on this, determine the total load rate of all access bearers; According to the Service Quality Metrics weighted factor of at least one carrying to be accessed, the load factor increment of at least one carrying to be accessed, and total load rate, obtain the Service Quality Metrics of at least one carrying to be accessed.

Further, the Service Quality Metrics of at least one carrying to be accessed adopts following formula to obtain:

Q=ρ+v _m' Δ ρ (formula two)

Wherein, the Service Quality Metrics that Q is at least one carrying to be accessed; The total load rate that ρ is all access bearers; Δ ρ is the load factor increment behind at least one carrying access to be accessed community, and its value is estimated value; v _m' be the Service Quality Metrics weighted factor.

In said process, the process of obtaining the Service Quality Metrics weighted factor of at least one carrying to be accessed is: each channel quality parameter of access bearer is added up respectively in base station, and according to this each channel quality parameter of access bearer, obtain the average channel quality parameter of all access bearers; According to the channel quality parameter of above-mentioned at least one carrying to be accessed, the average channel quality parameter of access bearer, obtain the Service Quality Metrics weighted factor of at least one carrying to be accessed.Wherein, the average channel quality parameter of all access bearers can adopt filtering algorithm to obtain, special, when each channel quality parameter changing value of access bearer within the specific limits the time, the average channel quality parameter of above-mentioned access bearer can adopt the channel quality parameter sum of all access bearers and the ratio of the number of access bearer, is about to this ratio as the average channel quality parameter of access bearer.

When channel quality parameter is signal to noise ratio, adopt following formula, obtain the Service Quality Metrics weighted factor of at least one carrying to be accessed:

${v_m}^{\&prime;}=\left\{\begin{array}{c}1-a\log \left(\frac{{\mathrm{SINR}}_{\mathrm{new}}+\left|k\right|}{\stackrel{\&OverBar;}{\mathrm{SINR}}+\left|k\right|}\right),{\mathrm{SINR}}_{\mathrm{new}}<\stackrel{\&OverBar;}{\mathrm{SINR}}\\ 1,{\mathrm{SINR}}_{\mathrm{new}}\&GreaterEqual;\stackrel{\&OverBar;}{\mathrm{SINR}}\end{array}\right.$ (formula three)

Wherein, v _m' be the Service Quality Metrics weighted factor of at least one carrying to be accessed; SINR _newsignal to noise ratio at least one carrying to be accessed;

for the average signal-to-noise ratio of access bearer; The channel quality parameter of value minimum in the channel quality parameter that k is all described access bearers, guarantee the validity of logarithmic function, preferably, when | when k| is non-integer, right | the k| processing that rounded up; A is the first corrected parameter, can get the positive count value, and preferably, a value is 0.8,1,1.5,2,3.

In addition, when channel quality parameter is signal to noise ratio, can also adopt following formula, obtain the Service Quality Metrics weighted factor of at least one carrying to be accessed:

${v_m}^{\&prime;}=\left\{\begin{array}{c}{b}^{(\frac{{\mathrm{SINR}}_{\mathrm{new}}}{\stackrel{\&OverBar;}{\mathrm{SINR}}}-1)},{\mathrm{SINR}}_{\mathrm{new}}<\stackrel{\&OverBar;}{\mathrm{SINR}}\\ 1,{\mathrm{SINR}}_{\mathrm{new}}\&GreaterEqual;\stackrel{\&OverBar;}{\mathrm{SINR}}\end{array}\right.$ (formula four)

Wherein, v _m' be the Service Quality Metrics weighted factor of at least one carrying to be accessed; SINR _newchannel quality parameter at least one carrying to be accessed;

for the average channel quality parameter of access bearer; B is the second corrected parameter, and its span is (0,1), take and guarantees that function is as subtraction function, any community of easy access user equipment request access while making channel quality better, this any community of more difficult access when channel quality is poor.

In formula three and formula four, work as SINR _newbe less than

the time, the formula that obtains the service quality weighted factor of at least one carrying to be accessed is subtraction function; All there is the parameter that guarantees function validity in above-mentioned subtraction function; And, work as SINR _newbe more than or equal to

the time, the service quality weighted factor value of at least one of acquisition carrying to be accessed is 1.In the embodiment of the present invention, when channel quality parameter is other parameters as CQI etc., the formula that obtains the service quality weighted factor of above-mentioned at least one carrying to be accessed all meets above-mentioned a plurality of condition simultaneously.

In said process, the process of the total load rate of all access bearers is: according to each rate requirement information of access bearer, the Physical Resource Block number that while obtaining the rate requirement that meets all access bearers, needs distribute, calculate the ratio of total number of the available physical resources piece of the above-mentioned Physical Resource Block number need distributed and above-mentioned any community, using this ratio as the total load rate of access bearer.Wherein, for arbitrary carrying, as access bearer or at least one carrying to be accessed, can calculate the load factor of this carrying according to the rate requirement information of this carrying, for different subframes, this carries also difference of corresponding load factor; Wherein, for GBR type carrying, due in related protocol regulation the type to carry corresponding load factor be fixed value, therefore can directly obtain; And for the carrying of non-GBR type, in related protocol and its load factor of no standard, therefore, the estimated value that the load factor of non-GBR type carrying obtains for the rate requirement information according to this subscriber equipment.Further, 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 the total number of the available physical resources piece of above-mentioned any community while meeting the rate requirement of this carrying.

Adopt technical solution of the present invention, the channel quality parameter of at least one carrying to be accessed that base station is corresponding according to subscriber equipment is obtained the Service Quality Metrics weighted factor of this at least one carrying to be accessed, wherein, the channel quality condition of at least one carrying to be accessed is better, the Service Quality Metrics weighted factor of this at least one carrying to be accessed is less, the channel quality condition of this at least one carrying to be accessed is poorer, and the Service Quality Metrics weighted factor of this at least one carrying to be accessed is larger.For example, when channel quality parameter is signal to noise ratio, the channel quality parameter of at least one carrying to be accessed is larger, and the Service Quality Metrics weighted factor of this at least one carrying to be accessed is less; The channel quality parameter of at least one carrying to be accessed is less, and the Service Quality Metrics weighted factor of this at least one carrying to be accessed is larger.As can be seen here, technical solution of the present invention takes into full account the channel quality condition of at least one carrying to be accessed that subscriber equipment is corresponding, when the rate requirement information of a plurality of at least one carrying to be accessed is identical, preferentially make the best subscriber equipment access community of channel quality condition, thereby avoided channel quality condition poor, and the network congestion that the very large subscriber equipment of rate requirement access community causes, and the high problem of reject rate during to the user equipment requests access community of other request accesses.

Step 220: after the Service Quality Metrics of judging above-mentioned at least one carrying to be accessed is less than or equal to default Service Quality Metrics threshold value, allow above-mentioned subscriber equipment to access this any community.

In the embodiment of the present invention, when the Service Quality Metrics of judging above-mentioned at least one carrying to be accessed is less than or equal to default Service Quality Metrics threshold value, allow the above-mentioned any community of above-mentioned subscriber equipment access; When the Service Quality Metrics of judging above-mentioned at least one carrying to be accessed is greater than default Service Quality Metrics threshold value, refuse the above-mentioned any community of above-mentioned subscriber equipment access.

Concrete, when the base station judgement meets following formula, allow the above-mentioned any community of subscriber equipment access:

$Q\&le;{\mathrm{\&rho;}}_{m,c}^{\left(\mathrm{th}\right)}$ (formula five)

Wherein, the Service Quality Metrics that Q is at least one carrying to be accessed;

for the Service Quality Metrics threshold value.The value of this Service Quality Metrics threshold value can be set in advance according to the difference of bearer types, for example, for the carrying of GBR type and the carrying of non-GBR type, different service quality threshold values is set respectively.

Special, when base station judges that the utilization rate of air interface resource of current time is less than or equal to default threshold value, by the Service Quality Metrics weighted factor assignment of at least one carrying to be accessed, be 1, and according to the load factor increment of at least one carrying to be accessed, the total load rate, obtain the Service Quality Metrics of at least one carrying to be accessed; After the Service Quality Metrics of judging above-mentioned at least one carrying to be accessed is less than or equal to default Service Quality Metrics threshold value, allow this above-mentioned any community of subscriber equipment access.

Consult shown in Fig. 3, below in conjunction with concrete application scenarios, with subscriber equipment access community A, this subscriber equipment is a corresponding example that is carried as to be accessed only, introduces in detail the process that subscriber equipment is carried out to access control:

Step 300: base station receives the access request message that subscriber equipment sends.

Step 310: the utilization rate of air interface resource of current time community A is detected in base station, judges whether this utilization rate of air interface resource is greater than default threshold value, if perform step 320; Otherwise, perform step 330.

Step 320: base station, based on above-mentioned access request message, obtains the Service Quality Metrics weighted factor of the carrying to be accessed that above-mentioned subscriber equipment is corresponding.

Step 330: the Service Quality Metrics weighted factor assignment that base station is above-mentioned carrying to be accessed is 1.

Step 340: the total load rate of access bearer is calculated in base station, and, based on above-mentioned access request message, calculates the load factor increment of carrying to be accessed.

Step 350: base station is according to the Service Quality Metrics weighted factor of above-mentioned carrying to be accessed, the total load rate of access bearer, and the load factor increment of carrying to be accessed, obtain the Service Quality Metrics of carrying to be accessed.

Step 360: base station judges whether the Service Quality Metrics of above-mentioned carrying to be accessed meets formula five, if perform step 370; Otherwise, perform step 380.

Step 370: allow above-mentioned subscriber equipment access community A.

Step 380: refuse above-mentioned subscriber equipment access community A.
